一只小鸟课件

一只小鸟课件收藏十二篇。

居安思危，思则有备，有备无患。在日常的学习工作中，幼儿园教师都会提前准备一些能用到的资料。资料的定义比较广，可以指生活学习资料。参考资料会让未来的学习或者工作做得更好！所以，你是否知晓幼师资料到底是怎样的形式呢？考虑到你的需要，小编特地编辑了“一只小鸟课件收藏十二篇”，欢迎大家参考阅读。

一只小鸟课件【篇1】

一、导入。

同学们，前几天我们写了一篇描写声音的作文，有许多同学在作文中都描写了同一种声音，是什么声音呢？听！（播放：鸟的叫声）对了，是鸟的叫声。请你再闭上眼睛仔细听听，想象一下这是一幅什么样的画面呢？（生答）

你说的真好，让我们大家有种身临其境的感觉。是啊，鸟儿的叫声多么清脆，多么好听，如果这世界上真的再也听不到鸟儿的叫声，再也看不到鸟儿在林间欢快飞翔的身影，那该是件多么遗憾的事情啊！可是，这样的事却真的发生了！

这节语文课，老师就和同学们一起来读读发生在一只小鸟身上的故事，好吗？（板书：一只小鸟；点课件）

二、初读课文，摸清脉络。

1、 翻开书，自己轻声的读读课文，看看自己是否把字音读准了，把句子读通顺了。

2、 那么文章写了这只小鸟的什么事呢？请同学们听老师来读遍课文，你画出自然段，并试着说说文章写了这只小鸟的什么事好吗？（一只小鸟的故事主要讲了：一只羽翼未丰的小鸟每天在树枝上歌唱，孩子们非常喜欢它，就用弹弓打伤了小鸟，两只老鸟接住小鸟把它带回了巢中。从此孩子们再也没有听到小鸟的歌声。）

3、 那么这是一篇叙事的文章，是按照事情的发展顺序来描写的。也就是说先写了事情的起因（板书），再写经过（板书），最后写结果（板书）。那么我们来看看这篇文章哪几个自然段写了1、这就是事情的起因，哪几个自然段写了2、这就是事情的经过，哪几个自然段写了3呢，这就是事情的结果？

三、品读细想，模仿想象。

1、弄清了课文的主要内容，我们也不得不接受了这样一个残酷的现实：那就是一只可爱的小鸟被人打伤了！是谁造成了这样的悲剧？原因又是什么呢？好心的同学们你们能在文中找到答案吗？（回答）你从哪看出来孩子们非常的喜爱这只小鸟呢？

2、让这么多的孩子都很喜爱的是一只什么样的小鸟呢？请大家在小组里读读第一和第二自然段，用笔画一画，再和同学说一说。一会再告诉大家行吗？

3、谁愿意读读第一和第二自然段呢？（生答）师：这真是一只快乐可爱的小鸟啊！

4、哪位同学能想象一下小鸟快乐的心情，到前面来表演一下这只可爱的小鸟呢？其他的同学和周老师都把自己当做自然中的一棵树或是一朵花，让我们用肢体来配合他一下，让我们含笑着倾听她美妙动听的歌声吧！

5、这么可爱的小鸟谁不喜欢呢？可是，不幸的事情还是发生了！一个弹子飞来，打伤了小鸟，当时的情况是怎么样的？谁能给大家读读？其他同学想想在这一部分你读明白了什么呢？

6、哪一位父母不爱自己的孩子，哪一位父母能眼睁睁的看着自己的孩子受到伤害？此时的他们心急如焚、此时的他们肝肠寸断。我们怎样才能读出老鸟当时的那种急切、悲伤的心情呢？同学们试试。

7、那么刚才还活蹦乱跳的小鸟呢？他怎么样了？你觉得这只小鸟怎么样？（太可怜了）我们看了心也会碎的！你能试着读读这一句吗？

8、这是一幅怎样的画面啊？一对悲伤焦急的父母含着眼泪望着自己受伤的孩子，孩子正痛苦的流着血。孩子们啊，我们怎么可以？怎么可以？让这么可爱无辜的小生命受到伤害呢？让我们齐读课文的最后两个自然段，边读边体会此时孩子们的心情。

四、拓展延伸、情感升华。

1、故事讲到这里你明白了什么？你想到了什么？能不能跟大家说说？如果让你跟那些打小鸟的孩子们说两句话，你会跟他们说什么？

2、光悔恨是没有用的，我们还必须用我们的实际行动去帮助小鸟，我们应该怎么做呢？请同学们看这个动画片，然后再说说。

3、教师激情结语，引出请爱护鸟类和人类共同的家园地球主题升华。

活动反思

本次微课我利用了最普遍最常用的手工折纸来进行教学，小鸟是幼儿在生活中最常见的动物，对于幼儿来说并不陌生。为了更好地呈现，我通过手机拍摄，制作步骤分解，并进行示范讲解，给幼儿一目了然的视觉效果。为了不让幼儿在观看时感到无聊生硬，我为视频加入了愉悦的背景音乐来给整个活动增添一丝生趣，微课录完后我觉得我有些地方只注重制作步骤，在活动导入部分过渡的有些仓促，在今后的微课教学中我会多加注意，注重每个细节。

一只小鸟课件【篇5】

一、说教材

《一只小鸟》是北师大版三年级上册《鸟儿》单元中的一篇主体课文，这篇课文，出自文学名匠冰心之手，语言清新流畅，是一篇非常优美的散文。文章主要讲了一只羽翼未丰的小鸟每天在树枝上唱歌，被孩子们打中后两只老鸟把它接住并带回巢中的事。文章以爱为主旋律，歌颂了亲情的伟大；批评了不成熟的儿童爱，因爱的方式不对，给鸟儿带来了伤害；告诉我们生命是平等的，人与自然之间应该是和谐的，我们人类应该爱护自然、保护自然，应该有一颗真诚的爱心。教育孩子们对于世间一切美好的事物，不仅要爱，而且要会爱，爱不是自私地占有，不是无情地伤害，而是欣赏、呵护和无私的奉献。

二、说教学目标、重难点、教学目标：

1、能够正确、流利、有感情地朗读课文。

2、通过学习课文使学生懂得应该爱护鸟类并理解亲情的伟大；

3、继续学习抓住重点词语，边读边想象，理解课文内容。

教学重点、难点：

1、能够正确、流利、有感情地朗读课文。

2、通过学习课文使学生懂得应该爱护鸟类并理解亲情的伟大；

3、继续学习抓住重点词语，边读边想象，理解课文内容。

三、说教学方法

学生升入三年级后，已经掌握了一定的观察想象、口头表达、交流合作、朗读等方面的能力，但是这些方面的能力都不强，比较薄弱，比如观察不细致，不能进行充分的合作交流，口头表达方面说话不够流利、完整、通顺，朗读水平不高等等这些能力都有待于老师在今后的教学中不断地培养，不断提高。针对学生的现状又结合教材的特点我设计了通过运用朗读法、小组合作交流法、图文结合法、理解重点词句法来进行本课的教学，并对学生各方面的能力进行进一步的培养和锻炼。

四、说教学过程

《小学语文教学法原理》告诉我们，语文教学中的阅读，是关系到培养读写能力和发展智力的一种发展性阅读。读一篇文章，先要让学生感知文字，从字词到句，从句子到段落，从段落到全篇，逐步读懂。结合《一只小鸟》一文的具体情况，在教学中的具体操作程序是这样安排的：

一、激趣导入

因本节课是第二课时的学习，一开始我便以昨天我们认识了一只小鸟朋友，今天它又来到了我们的课堂，大家还想继续了解它吗？导语导入，（通过小鸟朋友这样亲切的叫法，拉近学生与小鸟的距离，激发学生的学习兴趣）

复习，检查字词的掌握情况。

谁能说说课文主要讲了一件什么事？（检查学生对课文主要内容的掌握情况，锻炼学生的口头表达能力。）

二、细读课文，体会感悟

新课标要求，理解课文要以读为主，读中感悟，读中体会，俗话说读书百遍，其义自现。第一部分的学习我设计运用朗读、小组合作探究等教学方法突破重点。我设计围绕这是一只怎样的小鸟？你是从哪些地方看出来的？这个问题，从问题入手，让学生带着问题静心潜读课文，与鸟儿作心灵的吟唱，通过小组讨论学习，让学生充分发挥学习积极性，学会合作，学会探究，在愉快的交流过程中学会知识，再经过全班交流，学生对鸟儿的外形、活动、叫声应该已经有了一定的了解，鸟儿那机灵可爱的样子便会跃然纸上。如此可爱快乐的小鸟，我们应该怎样读才能体现出它的快乐呢？此时趁机指导学生有感情地朗读，让学生在读中感悟小鸟的可爱快乐，通过学生自由练读、指名读、生评读、老师适时的激发、导读，我想学生应该可以读得活、读出韵味。此时又我设计了同学们对第一部分的学生还有什么不懂或不明白的地方吗？这样一个质疑的环节，一方面可以训练学生提出问题、解决问题的能力，让学生学会质疑；另一方面可以点出重点，如啁啾是个生僻字（形容鸟儿的叫声）；有些学生可能不太理解，可以让学生帮助解答；再如自然在这里指大自然，不仅要让学生明白大自然除了有灿烂的阳光，葱绿的树木等等，还应该引导学生感受到因为有了小鸟清脆柔美的歌声，大自然的这种和谐的美才能够展现得更加淋漓尽致。这样一来，也就为解释鸟类是我们人类的朋友，我们应该爱护它们找到了依据。最后我又设计以学生用肢体语言表现小鸟快乐可爱的形象及欣赏关于小鸟的图片、叫声的环节把学生对小鸟的快乐、可爱的理解推向高潮。

第二部分（36）是文章的重点，这一部分的学习，我设计了抓住重点词句，理解课文内容学习方法突破重难点。如这句它正要发声，忽然啪的一声，一个弹子从下面射来，它一翻身从树上跌了下去忽然说明了什么？(意料之外)跌是什么意思为什么不用掉？（跌说明完全失去控制，很重的掉下来，说明鸟儿受伤很重）斜刺里两只老鸟箭也似的飞来，接住了它，衔上巢去。斜刺里不好理解，让学生通过观察画面，仔细观察图中两只老鸟的动作，通过适当的动作或手势从而理解斜刺里，加深学生对内容的理解，激发学生表达的欲望，有效地锻炼学生的观察能力和语言表达能力。箭也似的说明像箭一样速度飞快；另外通过飞来、接住、衔上一系列动词体现出老鸟救子的急切心情；它的血从树隙里一滴一滴地落到地上来。一滴一滴说明什么？（学生只要理解小鸟流血过多，受伤严重）刚才还活蹦乱跳的雏鸟就这样受伤，就这样失去了生机、清脆的叫声甚至也许是生命。此时孩子的情感从高峰跌入谷底，他们为小鸟的不幸而悲愤，自然而然地达到了共鸣：爱不能成为一种伤害，爱应该是欣赏、呵护和奉献。通过对斜刺里箭也似的一滴一滴等重点词语的理解，加之教师适时的指导朗读，学生自由练读、指名读等有效地、充分地朗读，我觉得学生应该能体会亲情的伟大。

三、想象拓展

三年级的学生已具有一定的观察想像、口头表达和交流合作的学习能力，因此我安排了让学生想象：（1）故事讲到这里，你想对谁说些什么呢？(对小鸟、对鸟爸爸、鸟妈妈、或对孩子们、对人类)这个环节的设计我让学生把肚子里的话都倒出来放心大胆地说出来，锻炼学生口头表达能力的同时考察学生对文章内容的感悟，使学生的情感得到升华。(2)消失的歌声又再次出现了，这是怎么回事？设计续编故事这样的环节，进一步的培养锻炼学生的想象能力以及口头表达能力。

五、作业设计

我本着让学生自由作业，快乐学习的目的设计了三项选作题：

1、续写故事：后来，消失的歌声又出现了，这是怎么回事呢？

2、登陆网站了解更多关于鸟类的知识；

3、设计并制作标语牌，写上你创作的保护鸟儿的标语。

六、板书设计

好的板书是一篇文章的袖珍版，是课文精华的体现；好的板书更应具有深刻的启发性。我的板书设计力求体现这些，设计时按照故事的发展顺序，体现了文章的思路，从板书中可以发现抓住重点、突破难点的途径，并能用较为清晰的思路引导学生复述课文内容。（出示板书设计图）

语文应该是广阔的，字词的积累，文章的品析，情感的升华都应是语文的内涵。而生活这片广阔的天地更应是语文的外延。教育的最高境界应该是达到三个和谐，即让孩子与自身和谐，与周围生命和谐，与大自然和谐。教学本文，除学习语文基础知识（写字、朗读、表达）之外，更多的应该让孩子懂得对生命的敬畏：真正的的喜爱是对鸟儿的疼惜、照顾和爱护、鸟儿只有是活的才是最可爱的。所以应该让孩子们学会真正的爱的方式。

一只小鸟课件【篇7】

学情分析：

本班学生共有60人，大部分来自农村或外来务工人员子女。三年级的学生，已初步形成了良好的学习习惯和学习方法，上课能专心听老师上课，认真做课堂笔记。有一部分学生还缺乏良好的学习习惯和正确的学习态度，对学习没有良好的认识，缺乏积极的学习态度，学习存在着惰性，喜欢依赖老师和家长，不是主动的去获取知识，靠的还是死记硬背。

教材分析：

本篇课文《一只小鸟》是北师大版小学语文三年级上册(五册)中第五单元的第二篇主体课文。本文的作者是冰心。文中主要讲了一只羽翼未丰的小鸟每天在树枝上唱歌、孩子们用弹弓大中了小鸟，两只老鸟接住了小鸟把它带回巢中。从此孩子们再也听不到小鸟的叫声。文章批评了不爱护鸟类的行为，歌颂了亲情的伟大。

3、生齐读课题。

二、学习课文1、2自然段。

1、通过上节课的学习，大家对课文有了大致的了解，相信文中的一只小鸟给大家留下了一定的印象，下面请同学们自学课文1、2自然段。

出示自学提示：

用自己喜欢的方式再读读课文1、2自然段，思考：这是一只（）的小鸟。

2、交流汇报

这是一只可爱的、幼小的、快乐的、幸福的、爱唱歌、歌声动听的、爱欣赏风景的小鸟。

你从哪些词句中看出来？

3、多美的景致，多可爱的小鸟，再加上小鸟清脆柔美的歌声，这是一副多么美丽、和谐的自然图画啊！让我们怀着美好的心情齐读课文1、2自然段。

三、学习课文3--6自然段。

鸟儿欢快的歌声吸引了树下玩乐的孩子，他们天天来听小鸟唱歌。可是有一天，一件令人心痛的事情发生了。

1、请同学们快速默读课文3至6自然段，画出自己感受最深的句子，并在旁边批注自己的体会或感受。

2、汇报交流。

（ 1）它正要发声，忽然"啪"的一声，一个弹子从下面射来，它一翻身从树上跌了下去。

从这句话看出小鸟的伤势很严重，"跌"是完全失去控制，很重地摔下来。抓住重点词指导朗读。

（ 2）斜刺里两老鸟箭也似的飞来，接住了它，衔上巢去。

从这句话能够看出老鸟对小鸟非常关爱，体会到亲情的伟大。"箭也似的"像箭一样快，说明它们此时此刻内心非常着急。抓住"箭也似的"指导朗读。

师：拿一位母亲不爱自己的孩子？哪一位母亲能眼睁睁地看着自己的孩子受到伤害？此时的它们心急如焚，此时的它们肝肠寸断，我们怎样才能读出老鸟当时那种急切、悲伤的心情呢？

自己试读，指名读，评议，齐读。

（3）它的血从树隙里一滴一滴落到地上来。

从这句话体会到小鸟的伤势很重可能有生命危险……

师：刚才还活蹦乱跳、高声鸣唱的小鸟转眼间正痛苦地流着血，正面临着死亡的威胁，你觉得此时是一只怎样的小鸟？（可怜的、不幸的、痛苦的、命运悲惨的……）

是啊！这是多么令人心痛的一幕啊！你能带着这种感受读好这句话吗？

试读，指名读，齐读。

五、学习课文7、8自然段。

1、此时此刻，假如你就是那些孩子中的一员，当你看见小的血从树隙里一滴一滴落到地上来，它的生命即将结束，你会怎么想？

指名说。

2、因为孩子的一时贪玩，让这么可爱无辜的小生命受到了伤害，让我们齐读最后两个自然段，边读边体会此时孩子们的心情。

3、文中的孩子们喜欢这只鸟吗？从什么地方可以看出？他们对小鸟的爱和老鸟对小鸟的爱有什么不同？

点生汇报。

师：小孩的爱是自私的，爱的方式不对，爱它就让它更加自由，爱它就应该让它更加快乐，爱它就让它更加美丽，爱不是占有。

六、拓展延伸，情感升华。

1、故事讲到这里，你明白了什么？如果让你对文中的孩子说几句话，你会说些什么？

2、师：听了你们这番话，相信那些调皮的孩子们会放下手中的弹弓，以一颗善心和爱心去对待鸟类。老师也想对文中的孩子们说几句话，可以吗？

出示白居易的《鸟》诗。

谁道群生性命微，一般骨肉一般皮。

劝君莫打枝头鸟，子在巢中望母归。

岂止是"子在巢中望母归",同样还有"母在巢中盼子归",古人尚且明白这个道理，何况我们今天的少年儿童呢？让我们一起读一读这首诗，向所有的人发出"莫打枝头鸟"呼声吧！

七、总结。

美丽鸟儿，美丽的生活，美丽的大自然，都需要我们用心去呵护，真正的喜爱不是占有，不是破坏，而是让美丽的事物更加美丽，让美丽的世界更加美丽。我们相信：只要人人都献出一点爱，世界将变成美好的人间

作业：每一只美丽的小鸟都对世界充满了幻想和希望，但文中的这只小鸟却怎么也没有想由于人类的贪婪使它惨遭不幸。小鸟的命运牵动着每个人的心，大家想像一下，那只小鸟后来怎么样了？续写一段话。

Prepare themselves for the coming examination

Summary after Class

The goals made before class have been reached quite well. The students took part in the games actively. They are quite pleased to accept this way of teaching.. However, the amount of knowledge they have really learnt by heart is a little less than we have anticipated beforehand . So we have to admit the fact that it is rather difficult to combine the communicative teaching ways with the current teaching conditions, in which we have such a large class including fifty-six students or so and the great pressure coming from the miscellaneous examinations.

Teaching procedure

Step 1 A competition for key phrases(10 minutes)

T: Good morning, boys and girls .Have you prepared well for the coming exam? Do you feel a little nervous about that ? Now let’s relax ourselves together. We will have a competition. We have four unknown slides. They are slide A, slide B, slide C, and slide D. Each slide has six phrases in Chinese on itself. In our class we have four groups. Every group can get a slide by drawing lots(抽签).In the end , we will see which group can translate all of these phrases into English correctly., Ok , now every group will send a student out to choose your slide.

Group 4 : (A)junk food, ought to , plenty of , keep up with , make a choice, now and then

Group 1: (B)dress up, in one’s opinion, play a joke on sb., take in, call on, bring back

Group 3: (C)pay off, at most, act out, a great deal of , a number of , pick out

Group 2: (D)around the corner, come to terms with, die down, day and night, take possession of, make up

T: Good job. You have finished it very well except for only one mistake. Group 3 have mixed up two phrases.

We should pay attention to the answer to NO.4 in the slide C, The right answer should be ”a number of”. And the answer to NO.5 in the slide C should be “a great deal of ”. Let’ look at another slide.

T: Group1, Group2, Group4 each have got 10 points. Congratulations! Group 3 has got 5 points. Try harder, guys.

Step 2 Design a form about those modal verbs which are used to express possibility.(18minutes)

T: Our competition will continue. We have learnt that “must , can/could, may/might “can be used to express possibility.

Can you try designing a form to make it clear how to use them in different sentence styles and different tenses. Group members should work together to get the best one in your group. Give you ten minutes to prepare for it.

T: Ok, the time is up. You can’t change it any more. Different groups can exchange your forms, and let’ s compare them with each other. Oh, which do you think is the best one?

Ss: We have agreed on the form made by group 3 .

T: Let’s have a look at it with the projector.

Modal verbs to Tenses

express guess or possibility Present

Or

Future

Present continuous Past

Or

perfect

Positive

sentences must:: very sure, certain

may

might perhaps, maybe

could possible

Modal

verb

+do/be

Modal verb

+be doing

Modal verb

+have done

Negative

sentences Can’t very sure

Couldn’t it is impossible

May not perhaps

Might not not

Question

sentences

Can/could

T: Well done. Your group deserve another ten points and the other three groups each have got five points

Pay attention to two points: (1)“mustn’t” means “You shouldn’t do it”, or “you are forbidden to do something.”. If you want to express you are sure that something is impossible, you should use “ can’t or couldn’t” to say that.(2)Look at the following examples.

a. He must be a student, isn’t he?

b. He must have finished it, hasn’t he?

c. He must have done it yesterday, didn’t he?

If we write the first part of each sentence without “must”, we’ll get three sentences like these.

a’. He is a student b’. He has finished it. c. He did it yesterday.

We got the second part of a, b, c from the sentences a’,b’,c’. Actually, we don’t try to guess any more in the second part of Sentence a, b, c.

Step 3 A game named “single or plural”(15mintues)

T: The following game is still played among groups. The knowledge you will use in this game is Subject-verb agreement.

T:(facing the group 1) Let’ s take Group 1 as an example. I have some phrases for your group members which can be used as subjects. As soon as I tell you one, you should tell me whether its predicate verb is single or plural. I will tell you my phrases one by one and you guys give me your answers one by one. You must do it as quickly as possible because you have only three minutes. Within three minutes, the group who has got the most correct answers is the winner Let’s have a try.

T: physics

S1: single

T: a library together with books

S2: single

T: not only the teacher but also the students

S: plural

… … …

… … …

T: Do you know the rule of the game , S10? Can you tell us something about it?

S10: Yes.I think every student has a chance to take part in the game. It’s very exciting.

T: Quite right. Remember only your first answer makes sense. Anyone can not answer it twice in the same round.

T: When one student is telling his answer, others should keep quiet. Let’ s start our game from group 4.

(maths, the number of students , a number of students, everything, both A and B, half of the food, half of the students, fifty percent of the population, ten pounds, works, every possible means , a clerk and secretary, every boy and every girl, more than one , many a , the pair of glasses, the glasses, bread and butter, the United States, cattle …)

高一英语课件 篇6

提问是阅读教学中使用得最频繁的教法之一。目前语文教学中已形成众多流派,不管哪一派都离不开设计 问题、提出问题、运用问题,开启学生心智,引导学生理解课文。那么究竟应该如何提问呢?本人认为,要研 究阅读教学如何提问,首先要探讨何以要提问。

作为一种教法,提问是师生课堂会话的方式。提问是一种言语行为,属“语用”范畴,提问时使用的问句 属“语形”范畴,而问句中包含的问题属“语义”范畴。

二十世纪科学哲学的一个重要成果,是发现智力活动的起点在发现和提出问题。英国科学家波普尔科学发 现的模式就是:“问题(1 )--假设(猜测)--验证--问题(2)”。因此, 问题也是教师启发学生, 打开思路,开发智力的钥匙。布鲁纳的“发现法”,第一步设卡,即让学生认识上产生矛盾,发现问题;第二 步设法,就是让学生运用已有知识框架或认识结构,在教师点拔下试作解答;第三步验证,如果解答正确,也 即动用旧框架同化了新信息,进一步丰富了已有的框架,如果错了则帮助学生调整或转换旧框架,形成新框架 ;第四步小结,即反馈、总结。认识心理学中的“SQ4R阅读方法”,首先是预习或概观,在此基础上即是“提 问”,然后精读(阅读、思考),最后是复述和复习,以加深记忆;其主要特征就在于提出问题、回答问题, 对教材进行细致、深化的加工。

阅读理解有不同层次。章熊先生分为:(1 )复述性理解(着眼于表层信息,侧重记忆);(2)解释性理 解(通过信息加工, 由表及里、由此及彼,转化为自己的认识);(3 )评价性理解(对文章价值作用评价) ;(4)创造性理解(超越本文,探索新问题,提出新见解)。按章先生的意见,四个层次由低到高排列,而中 学阶段的阅读理解应以一、二两项为本(注:《特级教师--专家学者之选》。)。理解的层次不同,问题的 层面和提问方法也会有所不同。例如,在低年级使用的谈话法适用于复述性理解,提出反常问题,克服学生思 维定势使用于创造性理解。本人认为,狭义的理解应指“解释性理解”,是实现阅读目标的关键,也是阅读智 力活动的核心,想象、欣赏、评价、记忆、创造、应用都以此为基础。

西方解释学是关于文本意义的解释和理解的一种理论与方法或哲学,有助于探讨“解释性理解”的本质。 解释学认为,阅读是读者和本文的对话、交流。伽达默尔说:“使留传下来的本文成为解释的对象,就意味着 它向解释者提出问题,……理解本文也就是理解这个问题”;而“问题的重建变成了我们自己的提问,这种重 建可以把本文意义理解为其回答”,“我们这些努力要求理解的人,必须通过自己让本文讲话”(注:《哲学 译丛》1986年第三期。)。作为接受者总是以提问者身份出现,而作为本文则以对答者身份出现,双方建立起 问答的伙伴关系;而理解就是通过对话、问答而达到“视界融合”的过程。所谓视界是一个从已有知识框架出 发所能理解的可能范围,读者不断从自己已有视界出发,进入本文的视界,形成一个既非自己也非本文的新视 界,具有新的可能性。达到理解的标准就是解释学家所说的“解释学循环”--整体只有通过理解它的部分才 能得到理解,而对部分的理解又只能通过对整体的理解。“解释学循环”有两层意思:

(一)古典解释学认为,作品自身作为整体包括意义、风格、结构等,作品的各部分诸如章节、词句等, 必须放在这个整体中才获得理解与意义;而作品相对于产生它的整个历史文化背景而言,又是这一文化背景的 部分,作品必须放在这一历史文化背景的整体关系中才能得到理解。对这一层次的“解释学循环”,钱钟书先 生表述得最为清楚:“乾嘉‘朴学’教人,必知字之诂,然后识句之意,而后通全篇之义,进而窥全书之指。 虽然,是特一边耳,亦祗初桄耳。复须解全篇之义乃至全书之指(“志”),庶得以定某句之意(“词”), 解全句之意,庶得以定某字之诂(“文”),或并须晓会作者立言之宗尚,当时流行之文风,以及修词异宜之 着述体裁,方概知全篇或全书之指归。积小以明大,而又举大以贯小,推末以至本,而又探本以穷末;交互往 复,庶几乎义解圆足而免于偏枯,所谓‘阐释之循环’者是矣。”(注:钱锺书《管锥篇》第一册,中华书局 出版。)

(二)当代解释学认为,更重要的是解释者的前理解(已有知识框架)形成的视野(整体)与作品(部分 )的关系。读者已有的知识框架是向本文敞开的倾向性,在已有框架引导下进行理解活动,同时也在理解活动 中受到检验、调整、修正,使本文的意义显现出来,因此理解决不是消极地复制本文,而是一种“生产性”、 “构成性”的努力。伽达默尔认为,理解永远是由整体(读者的前理解)运动到部分(作品),又回到整体( 读者所达到的新的理解)的理解。而所有部分与整体的和谐状态便是正确理解的标准。

根据当代认知科学研究成果,阅读理解同时存在两种信息加工方式:资料驱策加工和概念驱策加工(注: J.R.安德森《认知心理学》,吉林教育出版社出版。)。“资料驱策加工”是对来自本文的信息加工,本文从 低到高有如下分析平面:语音平面、书写平面、词汇语义平面、句法平面、语篇平面和语篇所指平面。对本文 各平面从高到低,从低到高的加工相当于“解释学循环”的第一层意思。可是读者的心智并不是一张“白纸” ,本文仅仅是信息的一个来源,其它信息还来源于读者头脑中已有的知识,一个人对有关本文的知识越多,理 解效果越好,就能以最短时间、最少努力,有选择地使用最有成效的线索探索文章语义和句法制约关系,从本 文中构造出意义,这种加工方式称为“概念驱策加工”。读者头脑中已有的知识相当于解释学家说的“前理解 ”,因此这种加工方式也相当于“解释学循环”的第二层意思。任何认识的发生、发展都是认识的外源因素和 认识的内源因素双向作用的结果,阅读也是双向建构,阅读理解要达到两个平衡:作为客观的本文的整体和部 分的协调,作为主体认知框架的平衡。

阅读教学中,教师的主导作用在于通过提问,引导学生达到“解释性理解”,起导读作用。这就要遵循“ 解释学循环”的原则,启发学生同时进行两种方式的信息加工,提高理解水平,培养迁移能力。

以上主要从解释学维度讨论了何以要提问,阅读教学中如何提问就有了根据。

课堂提问的组成是阶梯式的:最高层次是“课”,其次是“课段”,再次是“回合”(一次问和答),最 低层次是“话步”(教师的“问”和学生的“答”)。

我们先讨论“回合”。教师和学生的对话并没有信息沟,教师提问并不是要从学生那里获得信息,而是要 启发学生获得信息或检查学生是否已获得信息。一般会话结构是两话步:一种是A(问)--B(答),A(再问 )--B(再答);一种是A(问)--B(答),B(问)--A(答)。而课堂会话结构是三话步:T(教师问 )--S(学生答)--T(教师评价小结)。第三话步是信息的反馈, 即使有学生能作出正确回答,但不等于 所有学生都能回答,应重复学生的回答以面向全体学生。

由回合到课段,提问有一个开始到结束的框架,每次提问都有一个焦点,如何组织一个课段的提问呢?遵 循“解释学循环”的原则,大致有两种方式。

(一)由浅入深,由表及里。

1、由表层到深层,由具体到抽象。于漪老师《七根火柴》第21 节的提问设计是:(1)无名战士留给人间 的最后话语是什么?(2)无名战士留给人间的最后动作是什么?(这两个是表层问题。)(3 )这些言行显示 了他怎样的心灵、怎样的精神?(4)和一般人相比, 他的伟大之处是什么?(这两个是深层问题。)《截肢 和输血》第1 节提问:(1)白求恩同志是在怎样的气候下赶路的?(冷)(2)作者怎样描写冷?(这两个是 具体的问题)(3)作者着力描写气候寒冷的用意是什么?(这个问题较抽象。)

2、层层深入。如钱梦龙老师《捕蛇者说》第1节的提问:(1 )这种蛇特别,文中用了哪一个字?(“异 ”)(2)“异”在哪里? (归纳为:色、毒、用)(3)作者突出了哪一个?(“毒”)(4)为什么?(陪 衬赋敛之毒)(5)为什么永州人民还“争奔走焉”? (将捕蛇和纳税联在一起)后一问句的焦点以上一问句 提供的新信息为依托,层层递进。

(二)整体--部分--整体。

本人在教《白杨礼赞》第7节的提问设计是:(1)上一节从外形上写白杨树不平凡,本节从哪一方面赞美 白杨树的不平凡呢?(内在气质)(2)作者调动哪些手段赞美白杨树的内在气质?(排比、比喻、拟人、对比 、欲扬先抑)(3)“伟丈夫”和“好女子”对比, 这个“好”是什么含义?(美丽)(4)为什么要用这样的 对比和隐喻? (突出其壮美,并由赞美树过渡到赞美人)(5 )作者用什么手法进而揭示其象征意义?(反问 排比句)(6)这几个排比句之间有什么联系? (由外到内,层层深入)(7)四个反问句句式上有什么变化,

怎样逐步深化点出象征意义?(略)(8)这一节在全文起什么作用? (赞美的高潮所在,精华所在)。

在组织课段提问时,要防止孤立式的提问。一位新教师教读《挖荠菜》第2节提了三个问题:(1)“馋” 是什么意思?(2 )馋到什么程度? (3)饿到什么程度?关键要问:为什么要写馋(突出饿)和写“饿”反 映了什么,才能由表及里。

在课堂上,提问的展示由“回合”到“课段”,再到“课”;可是教师在设计提问时是从“课”到“课段

Disk Doctor

What can you if you lose the data from your disks? To find an expert, who would recover the lost information for you, is the easiest solution. Jack Olson is one of these experts, jack and a few of his friends set up a company called “jack’s disk doctor service” in 1984.They work from home and give all the money they earn to charity. The fees are always the same, no matter how precious the data on the disk is. Some people, however, are so grateful that they send extra money to jack or the charities his company supports. The fees are always the same, no matter how precious the data on the disk is. Some people, however, are so grateful that sent extra money to jack or to the charities his company supports, one oil company offered him ,000 for his help and an architect even sent him a blank check.

It would be difficult to put a value on the things rescued by the Disk Doctor. There have been disks containing medical research, television scripts, manuscripts of whole books, a lawyer’s papers for a court case and even Margaret Thatcher’s travel plan for a visit to eastern Europe. For this last case, jack had to go in person to Thatcher’s office “for security reasons”.

Disk is usually sent to the disk doctor by post, but some times people are in such a hurry that they can’t wait for the mail to come. For example, some radio scripts had to be rushed by taxi to jack’s house because they were needed for broadcasting the next day. When the material has been recovered, the disk is returned to the sender with a diagnosis and a prescription for avoiding the problem in the future, One grateful client, an author, put a “Thank you” to jack in the front of his book saved me from a heart attack,” he wrote.” but,”says jack “most people don’t take any notice of the doctor’s advice”

1. Role-play the dialogue in groups of five.

(Divide students into groups of five and one is the narrator and the others are the main characters. Role-play Act One and Act Two.)

There are three kinds of goals: short-term, medium-range and long-term goals.

Short-term goals are those that usually deal with current (当前的)activities, which we can apply on a daily basis. Such goals can be achieved in a week or less, or two weeks, or possibly months. It should be remembered that just as a building is no stronger than its foundation, our long-term goals cannot amount to very much without the achievement of solid short-term goals. Upon completing our short-term goals, we should date the occasion and then add new short-term goals that will build on those that have been completed.

The intermediate goals build on the foundation of the short-term goals. They might deal with just one term of school or the entire school year, or they could even extend for several years. Any time you move a step at a time, you should never allow yourself to become discouraged or overwhelmed. As you complete each step, you will enforce the belief in your ability to grow and succeed. And as your list of completion dates grow, your motivation （动力）and desire（欲望） will increase.

Long-term goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing. We should never allow a long-term goal to limit（限制） us or our course of action.

1. Our long-term goals mean a lot ________.

A. if we cannot reach solid short-term goals

B. if we complete the short-term goals。

C. if we have dreams of the future

2. New short-term goals are built upon________.

A. a daily basis B. your achievement in a week

C. current activities D. the goals that have been completed

3. When we complete each step of our goals, _____________.

A. we will win final success B. we are overwhelmed

C. we should build up confidence of success

D. we should have strong desire for setting new goals

4. What is the main idea of this passage? _____________

A. Life is dynamic thing. B. We should set up long-term goals.

C. Different kinds of goals in life. D. The limitation of long-term goals.

5. Which of the following statements is wrong according to the passage? _____________

A. The long-term goals cannot amount to very much without the achievement of solid short-term goals.

B. The intermediate goals build on the foundation of the short-term goals.

C. Life is a static thing, thus we should never allow a long-term goal to limit us or our course of action.

D. We should often add new short-term goals to those which have been completed.

1. PRESENTATION & REVISION

Talk about the teaching plan for this unit and at the same time tell the students the teaching aims and demands. During this period, do WARMING-UP, LISTENING, SPEAKING.

2. WARMING-UP

Introduction This activity provides a good opportunity to talk about creativity and to practise problem-solving skills.

Instruction When the students have solved the problems, ask them how they did it and compare different solutions. Ask the students what creativity is and if it is possible to learn how to be creative.

Answers:

Useful Things Various answers are possible. Encourage the students to think of as many uses as possible. It is not important if the new use is useful in the conventional sense, the emphasis here is on having students explain why / how it will be useful.

Talk box Various combinations are possible. Examples: 1st row left to right: stop, side, soot, stem. 2nd row left to right: coat, code, cram. 3rd row left to right: aide, atom. 4th row left to right: pram, poor. Students can also go right to left and diagonally - the more ways the better. Again, the emphasis is on having students explain their choices and solutions. The activity is not about getting the “right” answer.

True or False Answers: T-F-T. Ask the students how they came up with the answer and encourage them to think of more true or false questions.

Extension Ask the students to come up with more creativity tests.

3. LISTENING

Introduction The students will hear descriptions of everyday objects and are asked to try to guess what is being described. The exercise will be more useful and interesting if you encourage the students to move beyond the obvious uses of the objects described.

Instruction Tell the students to listen to the tape and try to guess what is being described. Before they listen to the tape, you can ask them to describe an everyday object (or you can bring two or three objects and describe them). When the students have listened to the tape and guessed what's being described, they can work in pairs or groups to discuss how the objects can be used. Encourage the students to think of new uses for the objects in addition to the “normal” uses.

Extension Ask the students to think about other objects that either fit the description or can be used for the same things.

LISTENING TEXT:

1 These are very simple. Two sticks, about 20 centimetres long. They are usually made of wood. You hold the two sticks in one hand. You put one stick between two of your fingers, and you hold the other one with your thumb. These things can be difficult to use at first, but you will soon learn how to pick up even small pieces of food.

2 This thing is very popular and useful. Almost everyone has one these days. You can see people using this thing on the bus, when they are walking, or at home. It is usually small, about the same size as your hand, and it comes in many colours. There are several buttons on it, some for numbers, others for other things. It can be put in your pocket or in a small bag. With it, you can talk to people far away.

3 This is a large box with a big door. If you open the door, a light comes on and you can see what's inside. You'd better not leave the door open for too long, because it is not good for the things inside. You might catch a cold, too, if you stand in front of the open door. There are several shelves inside, some in the box itself, some in the door. You usually find this large box. in the kitchen.

Various answers are possible.

4. SPEAKING

Introduction This group discussion is an opportunity for the students to practise their ability to express, support, and challenge an opinion. Jane wants to buy a cellphone, but before she buys one she wants to know what her parents and her friend think. The students will role-play the discussion.

Instruction Divide the students into groups and explain that they are going to prepare a role play and have a discussion. Each group member will play one of the roles and must prepare a role card. If necessary, you can use one of the role cards as an example. Explain the “rules” of the discussion to the students and remind them of the basic classroom rules.

1 Decide who will play which role. The student who plays Jane will be the group leader.

2 Give the group enough time to prepare the role cards.

3 Check that all group members are ready. Before the students begin the discussion, remind them that Jane should open the discussion and that they should take turns introducing themselves and stating their opinion as outlined in 4 and 5.

4 Jane opens the meeting by welcoming everybody. She also explains why they are meeting and asks everyone to help her make her decision.

5 Each group member introduces himself / herself and states his or her opinion and reasons.

6 When all the group members have introduced themselves and stated their opinions and reasons, the students can continue the discussion as they see fit. They can ask questions, give more examples and reasons, explain their opinions, and debate and challenge other views.

7 Remind the students that each group member must try to make the others agree with him or her.

Possible answers:

Jane

1 I can use a cellpho_e to call my parents if I am late.

2 I can use a cellphone to call for help.

3 I can use a cellphone to stay in touch with my friends. Jane's best friend

1 we don't really need cellphones.

2 we are not allowed to use cellphones in school.

3 it is better to use the money for something more important.

Jane's mother

1 cellphones are too expensive.

2 Jane should not spend too much time on the phone.

3 Jane is too young to have a cellphone. Jane's father

1 if Jane has a cellphone, I can always find out where she is.

2 a cellphone will help Jane feel safe.

3 Jane can use a cellphone send messages to her friends.

Sample discussion:

JANE: Thank you for taking the time to talk with me. Mum, Dad, you know I have told you before that I want to buy a cellphone. I would like to tell you why I want to buy one, and I would like your advice.

DAD: OK, why don't you start and then we will all tell you what we think.

JANE: Thanks, Dad. I think a cellphone is very useful, because I can use it to let you know where I am and when I will be back home. For example, if I have to stay late at school, you might get worried and wonder where I am. If I have a cellphone, I can call you and tell you that I will be late. .

MUM: Well, that's true, but I don't think you should buy a cellphone. In my opinion, a cellphone is too expensive. Besides, if you have a cellphone I think you will spend too much time talking on the phone. You'd better use your time to study instead.

CINDY: I agree with Mrs Collins. Some of the other students in our class have cellphones and they talk on the phone all the time. I don't see how they ever have time for anything else. And it is expensive. One of my classmates said that she spent 110 yuan in one month!

DAD: Jane, I think you are right. I often worry about where you are and I never know when I will be home from work. I remember last year, when you were at the supermarket and I had promised to pick you up. I was late and couldn't find you when I got there. If you have a cellphone I can just call you.

JANE: Thank you for telling me what you think. I will take some time to think about what you have said. Now let's have some fun. How about playing some cards!

5. SUMMARY & HOMEWORK

1. Preview the reading text

2. Learn the new words and expressions by heart.

3. Get ready to be examined in the speaking activities.

Period 2

1. PRESENTATION & REVISION

1. Ask some pairs to act out the speaking activities.

2. During this period, do some reading.

2. PRE-READING

Introduction The questions are designed to get the students to think about the cellphone as an example of inventions that have changed our way of life.

Instruction Encourage answers and comments that help students think about the way technology affects our life and thinking. The second question will help: students are likely to mention what we do today and compare to what people did in the past. Big inventions would include cars, computers, electricity, etc. The third question will help the students reflect on why some inventions are more popular than others.

Extension Ask the students to think about what “big” inventions have in common. Encourage students to think more about question 3. What are the consequences of “popular” science - will it lead science in the wrong direction?

3. READING

LIFE ON THE GO

Introduction The reading discusses the increasing popularity of cellphones in Chinese society. Cellphones are everywhere and have positive and negative effects on our life. Encourage the students to take a critical view of the cellphone culture, or life on the go, and think about how trends and life-styles are related to science and technology. Note that Wang Mei (the girl in the text) says that cellphones are useful and repeats the reasons we encounter in ads and the media - but in the last paragraph we also learn that she (like most people) actually uses the cellphone for other, perhaps less grand purposes. .

Note Life on the go refers to a fast-paced lifestyle where people are always on the go-rushing from one place to another, doing many things at once, and using portable phones, computers, etc.

Instruction

1 Ask the students to read the rust paragraph quickly to get the main idea of the text.

2 Ask the students to do the following (without reading the text).

A Try to guess what the next paragraph will talk about.

Ask the students what they think and why they think so. Compare different answers.

B Try to guess what the whole text will talk about. Ask the students what they think and why they think so. Compare different answers.

3 Ask the students to use the answers from 2A and 2B to write a simple outline of the text. The students can work in pairs or groups to write the outline.

4 Let the students read the whole text. Ask them to compare their outline with the text and note any differences.

4. POST-READING

Answers to Exercise 1:

1 The title refers to the high pace of modem life and to the fact that portable devices, like cellphones and laptops, are becoming popular.

2 The text lists a couple of reasons: cellphones can distract students in class, cellphones may make students spend more time talking on the phone than doing homework.

3 The text lists two reasons: safety and the cool factor, i.e. the desire to be like others. Students may add other reasons.

4 Students are of course free to agree or disagree. Make sure that the students give reasons for their opinion.

Questions 2 and 3 can be answered by skimming or scanning. For question 1, students may use the pre-reading discussion and their own thinking. The text does include the phrase life on the go, so additional help is available. Question 4 is perhaps best answered after a pair or group discussion.

2 Sample Outline

1 Wang Mei is an example of Chinese teenagers who have cellphones.

2 Cellphones can be used for many things.

For example: talking to people, sending mes5ages and pictures, .playing games, listening to music, keeping appointments

3 Cellphones also cause problems.

1 In school, cellphones may disturb lessons.

3. INTEGRATING SKILLS

Instruction Writing this letter can be difficult as the students will have to struggle with the abstract concepts. Most of them will find it difficult to capture the essence of the abstract terms, but in the process of doing so they will discover useful techniques for conveying their ideas, e.g. giving examples. Acceptable essays should include a rough definition of the two terms (love and friendship), with examples, within the framework of a letter to Q12. Advanced essays should use the definitions / examples to show Q12 that love and friendship are necessary, i.e. advanced essays should use the expository parts to support a persuasive thesis. These are important criteria for assessment. Let the students read the story about Q12 and then write the letter. The students can work individually or in pairs or groups.

Sample writing:

April 3 2374

Dear Q 12,

My name is Xiao Hong and 1 am a middle school student in Dalian. I would like to tell you about two things that 1 think are very important. Please read what 1 have to say, because 1 think it may be helpful to you. 1 want to tell you about love and friendship.

Love is difficult to explain, but 1 will try. Love is a feeling between two people. It is a very happy and warm feeling. When two people love each other, they almost become one person. For example, if a father loves his child, he will feel sad when the child is sad and happy when the childis happy. There are many different kinds of love: you can love your parents or children, you can love your husband or your wife, or you can love someone outside your family.

Friendship is also a kind of love. When two people are friends, they try to understand and help each other. A good friend will be there for you even when you are having a difficult time. Friends do things together and share thoughts, feelings and ideas.

Love and friendship are necessary if we want a happy world. If there is love, people will not do bad things to each other; if we have friends, we won't have to feel lonely or afraid. When people feel lonely and afraid, they often get angry with others and do mean things. If we learn to love and be friends, we can live happily together and solve the problems and difficulties we must face in life.

Your friend,

Xiao Hong

The words “chelyabinsk” and “Irkutsk” may be new to us, but the sentence tells us that they are examples of large Russian cities.

2. LISTENING

Instruction Tell the students that they will hear about the International Space Station. Ask the students what they know about it and then let them listen to the tape I and complete the informati0n chart.

LISTENING TEXT:

The International Space Station

As you are listening to this, the International Space Station is moving around the Earth. The International Space Station is an international project to build a small city in space. Sixteen countries are working together to build a space station where scientists can conduct experiments and learn more about space and the earth. The sixteen international partners are the United States, Russia, Canada, Japan, Brazil, and the European Space Agency. The United States and Russia are leading the effort but every country is making an important contribution to the ISS.

The International Space Station is made up of several parts and will be about the size of two soccer fields when completed. The different parts will be added one by one. Some parts are laboratories, some are for power sources, and others are for people to live in. The parts will be put together in space. When the new parts have been put together, space station astronauts will perform space walks to connect the parts to the station. The space walks are very dangerous and astronauts must be very careful one small mistake could be deadly! A total of 46 flights

will be necessary to connect the more than 100 parts. If all goes well, the station will be completed in a few years.

Note: The Europen space Agency involves 11 countries: France, Germany, Italy, Switzerland, Spain, the Netherlands, Belgium, Denmark, Norway, Sweden and the UK.

Answers to the exercises:

1

What is the task of the ISS? It is an international project to build the Internationals Space Station, a small city in space.

How many countries are building the station? 16

How big will the ISS be when finished? About the size of two soccer fields.

How many parts are needed? What will they be used for? More than 100.

Some parts are laboratories, some are for power sources and others are for people to live in.

How is the ISS being built? First, the different parts will be put together in space. Then, the people who work at the space station will take space walks to connect the parts to the station.

How many flights are needed to connect the parts? 46.

When will the project be finished? In a few years.

2 Various answers are possible.

3. TALKING

Instruction Help the students prepare the lists of advantages and disadvantages. You can use one of the examples and let the whole class think of advantages and disadvantages and then write them on the blackboard. If necessary, you can also model one or two “turns” in the debate.

Technology Advantages Disadvantages

Cellphones ●Cellphones help us keep in touch withour friends and family.

●Cellphones help us send e-mails.

● Cellphones help us send photographs and messages.

. ● Cellphones help us… ●Using a cellphone is expensive.

●Overusing it may disturb our work.

●Spending too much time making phone calls. . Cellphones ...

Robots

●Robots can work in dirty and dangerous places.

●Robots can do boring things that humans do not want to do.

● Robots can work without sleep and food. ●Robots can't think or make decisions.

● People may become unemployed if robots are used instead of humans.

●Robots need electricity.

Computers

●Computers help us work faster.

●Computers can help us study and learn.

●Computers can help us solve difficult problems. ●Computers are expensive.

●Computers can't think or make decisions.

●Computers are sometimes difficult to use.

Sample Dialogue:

A: I think that cellphones have many advantages. They help us keep in touch with our friends and family and we can use them to get important information, like news and weather reports.

B: Well, maybe, but there are many disadvantages, too. Cellphones are expensive to buy and use, and people may use them where they shouldn't, like in the classroom. Many people call their friends just for fun and may end spending too much time on the phone.

A: That may be true for some people, but that's not really because of the phones. You could say the same about TV or computers. People shouldn't do too much of anything. Think about all the other advantages. For example, if I'm meeting my Mum at the bus station and she is late, she can call me and let me know so I won't have to worry or get lost. And if I do get lost, or if I'm in danger, I can call for help.

3. INTEGRATING SKILLS

Reading

FUTURE TRAVEL: TELEPORATION

Introduction The text states that the concept of transportation has remained the same despite advances in science and technology. However, recent discoveries suggest that we may be able to change the way we view transportation. The text defines and explains teleportation and reports advances. in science that have made teleportation seem possible. The discovery is an example of how something once believed to be science fiction (or impossible) is becoming science (or reality). It is important to note that while the discovery described in the text is significant, the teleportation of human beings does not seem possible.

Extension Encourage the students to think about what a concept is and how it changes - or, in other words, how the way we think about the world interacts with what we know about it. Use the Adventure Travel reading in the student's book as an example of another conceptual change.

Answers to the exercises:

1 1 Teleportation is a combination of sending information through telephones or the Internet and transportation.

2 With normal transportation, a person or thing is moved from point A to point B. With teleportation, a person or thing is taken apart at point A and put together again at point B.,

3 Teleporting a human being would be very difficult since there are so many parts in a human body.

4 Various answers are possible. The text does make it clear that it. is very unlikely that human teleportation will become possible.

2 The students are asked to match each new word with the correct strategy. Ask them to scan the text for the word and then decide which strategy they could use to guess the meaning of the word.

Teleportation

Strategy: Some words are made up of two parts. We can use the meaning of each part to guess the meaning of the word.

The text emphasizes the mix of telephone and transportation and the students can use this to conclude that tele has been added to -portation to make up teleportation, meaning a combination of regular transportation and telecommunication.

Photons

Strategy: Some words are explained in the sentence. The explanation is often between commas (,), dashes (-), or brackets ( ).

The explanation is given in brackets in the text (particles that carry light).

Apart

Strategy: We can use words we already know to guess the meaning of words that mean the same or that have the opposite meaning.

The students are already familiar with the phrase put together and can use this knowledge to conclude that apart means the opposite of together.

3 1 People used to think it was impossible to use machines to talk to each other, but it has become possible with the invention of the telephone. In the future, we may even be able to use machines to send our thoughts to other people.

2 People used to think it was impossible to make a copy of a living thing, but it has become possible with the invention of cloning. In the future, we may even be able to clone human beings.

3 People used to think that it was impossible to make a machine that could do math, but it has become possible with the invention of the abacus and the computer. In the future, we may even be able to use machines that can think.

4. WRITING

Instruction Ask the students to think of inventions that have changed the way we live, e.g. the steam engine, electricity, the telephone, the computer, the Internet etc. What will the next big invention be and how will it change our life? The students are free to come up with their own ideas. Remind the students that they should give the new invention a name, explain (roughly) how it works or what it is, how it will be used (or what it will be used for) and how it will change our life.

Sample writing:

The Thinkuter

I think that the next big thing, the next important invention, will be a computer that can actually think. I don't mean that this computer will be like a human being - it will not be able to come up with its own ideas

but it will be able to help us think. The computers we use today can only do very simple things, like adding and subtracting, or storing and recalling information. The new machine will be able to do things that we do when we think. Since it is a computer that can think, I will call it a thinkuter.

If we have thinkuters, we can do things that used to be impossible. For example, today, with normal computers, only a few very smart people can solve important problems. And even these experts can only solve the problems in the same way. With a thinkuter, we would be able to think in new ways and change the way we understand life, science, and nature. A thinkuter would give us more thinking power and we would be able to do more with our ideas. Everybody has lots of good ideas, even children do, but it is difficult to turn one's ideas into reality. If people had thinkuters, they could use their ideas better - no idea would be wasted.

With thinkuters, we would also need to spend less time in school. We could learn more and faster. School is good for us and we need it, but if we could learn more and faster, we would have more time to do other things that are also important.

阅读下列短文，从每题所给的'四个选项（A、B、C和D）中，选出最佳选项，并把答案写在答题卷上。 A．

A car needs gas to run and your body also needs food to work for you. Eating the right kind of food is very important. It can keep your body strong, so take care of what you eat.

There are four main food groups altogether. The dairy products group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all the four main groups. With all these food together you will be given enough energy during the day.

It is easy to get into bad eating habits. You may eat your breakfast in a hurry to get to school on time. Or you may not have time for a good lunch. It may seem easy to finish your supper with fish and chips all the time. But you will find yourself tired during these days and you can not think quickly.

Watching what you eat will help keep your body healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having a good eating habit with some exercise is the key to your health.

31. Which of the following diets do you think is the best one?

A. Eggs, tomatoes and chicken.B. Milk, bread, cabbages and beef.

C. Corn, fish, cream and pork. D. Rice, beancurd, apples, fish and chicken.

32. Which of the following is a good eating habit?

A. Going to school without any breakfast.B. Eating fish and chips for supper all the time.

C. Finishing your lunch in a very short time.

D. Having at least one food from all the four groups each meal.

33. In this passage the writer mainly tells us that ______.

A. every person needs food to grow wellB. taking exercise can keep your body strong

C. right kind of food with exercise will keep you healthy

D. enough energy helps people think more quickly

B.

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.

Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.

Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little a amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.

Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

34. According to the passage,_________.

B. if we were healthy, we could spend our days in doing things with less sleep

C. one can eat a lot to stay in good shape

D. one needn't take any exercise if he is healthy

35.In order to keep good health, ___________ .

A. we should eat a lot of sweets B. one needs a large amount of fat

C. people should eat according to the foods nutrition D. we must try to sleep now and then

36. Eating more and sleeping less________.

A. can keep healthy B. is no good for you

C. gets you more energy D. will keep your personality

37.The writer explains ________in this passage.

A. how to eat B. the importance of doing exercise

C. how to keep healthy D. what to eat

38.The title of the article should be___________ .

A. Eating and Exercising B. How Vitamins Work in Man's Body

C. Staying Healthy D. Sleeping Well

C.

Isn't it astonishing how much time we spend talking about food? “Have you ever eaten …?” “What did you have for lunch?” and so on. And yet when you travel from one country to another, you will find that people have quite different feelings about food. People often feel that what they eat is normal (正常) and that what other people eat is strange or silly. In most parts of Asia, for example, no meal is complete without rice. In England, people eat potatoes every day. In the Middle East, bread is the main part of every meal. Eating like so many things we do, becomes a habit which is difficult to change. Americans like to drink a lot of orange juice and coffee. The English drink tea four or five times every day. Australians drink a great deal of beer, and the French drink wine every day.

The sort of meat people like to eat also differs from one country to another. Horse meat is thought to be delicious in France. In Hong Kong, some people enjoy eating snakes. New Zealander eat sheep, but they never eat goat meat. The Japanese don't like to eat sheep meat be-cause of its smell, but they enjoy eating raw fish (生鱼).

So it seems that although eating is a topic we can talk about for hours, there is very little common sense in what we say it. People everywhere enjoy eating what they have always eaten, and there is very little we can do to change our eating habits.

39. Which of the following is true according to the article?

A. All people have the same feeling about food.

B. In most parts of Asia, people usually have rice for meals.

C. People often consider other people to be strange or silly.

D. The topic people spend time talking about is bread and meat.

40. People in different countries .

A. drink the same sort of wineB. have the same eating habit

C. eat different kinds of meatD. have the same tea at different time within a day

41. The Japanese don't like to eat sheep meat .

A. because they dislike its smellB. because it is too expensive

C. because it is easy to go badD. because they think it will do harm to their health

42. English people drink tea four or five times a day .

A. because they get thirsty easilyB. because there is plenty of tea in Britain

C. because of their drinking habitD. because they have enough time to do so

捉迷藏课件(收藏十二篇)

我们常说，机会是留给有准备的人。在幼儿园教师的工作中，经常会提前准备一些需要的资料。资料通常是指书籍、报刊、图表、图片等。参考相关资料会让我们的学习工作效率更高。只不过，你是否知道有哪些幼师资料种类呢？以下是小编收集整理的“捉迷藏课件(收藏十二篇)”，有需要的朋友就来看看吧！

捉迷藏课件【篇1】

活动目标：

⒈尝试将三种水果按一维特征（形状或颜色）进行对应匹配。

⒉体验参与操作以及在活动中发现的乐趣。

活动准备：⒈已有经验：幼儿对常见水果的名称、形状、颜色有初步的认识

⒉黑色手工纸和透明塑封纸做成的苹果、梨、香蕉人手一份，红、黄、绿颜色的底板纸

活动过程：

一、 水果宝宝捉迷藏进行导入

小朋友，你们玩过捉迷藏的游戏吗？怎么玩的？今天我们的水果朋友也想和我们“捉迷藏”的游戏你们高兴吗？

现在它们已经躲起来了，可是它们的影子留在我们的小椅子下面，快到你们的小椅子下把它们找出来吧。

二、匹配水果的形状

⒈找到了吗？你找到的影子是哪个水果朋友的？谁找到的和他一样？你找到了吗？我也找到了，你看我找到的影子是哪个水果朋友？（香蕉）谁找到的也是香蕉？让我们看一看。轻轻告诉你旁边的朋友，你找到的影子是谁的？（幼儿相互看看说说）

水果朋友有点累了，要到家里先休息一会，看，这里有几个家啊？我们一起数一数？我们要把苹果、梨、香蕉送到和它们形状一样的家里休息，想一想，你的水果朋友要住在哪个家里呢？（幼儿思考片刻），送水果朋友到自己的家里去休息吧。（幼儿操作）

⒉宝宝们真厉害，把我们的水果朋友都送去休息了。我们一起来看看它们吧。

（1）、什么水果在这个家里休息啊？它长是什么形状？这个家是什么形状？（圆圆的苹果在圆圆形状的家里休息）

如果发生错误：我们看看——的家里是不是都是——的——在休息

（2）、这是谁的家？（梨的家）它的形状和梨的形状是一样的，上面是小小的，下面是？（大大的）（一头小一头大的梨在一头小一头大的家里休息）

（3）、这个家是什么形状的？谁在弯弯的家里休息？香蕉也是（弯弯的）（弯弯的香蕉在弯弯的家里休息）

小结：原来我们的.水果朋友长得都不一样，苹果的是圆圆的，梨是一头小一头大的，香蕉是弯弯的。

三、发现水果的颜色

⒈水果朋友休息好了，它们又想和你们捉迷藏了，你们准备好了吗？赶快把小眼睛捂住，不许偷看哦！（拿出透明的）好了，它们躲好了！这次，水果朋友脱掉了身上的衣服，躲在你们的桌子上，快把它们找出来吧。

⒉找出一个水果朋友回到位子上。（幼儿每人找一个塑封纸做的透明水果图片）

这次水果朋友们脱掉了衣服，你们还认识它们吗？你认出他了吗？是谁？你的水果朋友是谁？虽然水果朋友脱掉了衣服，可是你们还是认出了它们，真棒！

⒊现在水果朋友觉得有点冷了，想请你们帮它们穿上衣服，看一看这里有几件衣服啊？是怎么颜色的？你平时看见的苹果、梨、香蕉是什么颜色的，（走进幼儿）想一想应该帮你的香蕉穿什么颜色的衣服？（幼儿说）帮你的梨穿什么颜色的衣服呢？（幼儿说）

现在去帮你的水果朋友穿上它们喜欢的衣服吧！

（幼儿操作）

⒋你们帮香蕉朋友穿上了什么颜色的衣服？看看香蕉朋友平时是不是穿这样颜色的衣服（出示ppt）它真的穿着你们帮他选的黄衣服！我们看看香蕉是不是都穿上了黄衣服啊？（纠错）

捉迷藏课件【篇2】

捉迷藏课件【篇4】

设计意图：

捉迷藏是很有趣的游戏，深受孩子的喜欢。《小黑捉迷藏》绘本就是以这个有趣的游戏为线索，贯穿整个故事。绘本故事中，小黑飞到天空中和小鸟做游戏，让孩子们感受到自由和快乐；小黑走在马路上，又让孩子们懂得了在马路上安全很重要。小黑就像我们的孩子一样，对世界充满了好奇，对生活充满了期待，每一个画面，每一个场景都带给小黑和我们无限的想象。在设计本活动时，根据小班幼儿的年龄特点，通过“藏一藏——看一看——说一说——找一找”，让幼儿观察、讲述“小黑”藏在什么地方，不仅培养了幼儿的观察和想象能力，同时通过学习空间方位词，增加词汇量从而构建短句，提高了幼儿语言表达能力。

活动目标：

1、观察绘本画面，尝试用“小黑藏在XX”的句式讲述自己的发现。

2、能在不同色彩、不同情境的图片画面中快速地找到小黑的位置。

3、在游戏中快乐地去寻找，感受发现的乐趣。

活动准备：

1、知识经验准备：初步掌握简单的空间方位词汇；会玩“捉迷藏”的游戏。

2、物质材料准备：《小黑捉迷藏》课件；“小黑”若干；盒子一个。

活动过程：

一、游戏“找小黑”，引发兴趣，了解小黑的基本特征。

1、今天我们班来了一位新朋友，我们请它出来好吗？（幼儿请出新朋友小黑）

2、出示小黑：看看它长什么样？（圆圆的，黑黑的）它的名字就叫小黑。（和小黑打招呼）

3、小黑最喜欢玩捉迷藏的游戏，它现在就藏在我们的教室里，请你们把它找出来，找到的孩子就回到座位上。

4、你在哪里找到的小黑？（幼儿讲述）

二、结合课件讲述故事，寻找小黑，感受猜想和发现小黑的乐趣。

1、P1（盒子）小黑的家住在一个方方的盒子里，它要出来玩捉迷藏的游戏了。2、2、P2（草丛、瓢虫）小黑开始捉迷藏了，它藏在哪里？（教师边点中小黑边拖动到瓢虫的小壳上）（幼儿一起说“小黑藏在了瓢虫的小壳里。”）

3、P3（蜻蜓）看看这是哪儿？小黑会藏在哪里呢？小黑藏在……（教师边点中小黑边拖动到蜻蜓的眼睛上）

4、P4（乌云、小鸟）这次小黑又会藏在哪里呢？为什么要藏在这朵云里？颜色一样吗？（一起说说“小黑藏在……”）

5、P5（汽车）如果你是小黑，你还会躲到哪里呢？我们来看看小黑和你们想的一样吗？（请幼儿上前来点击小黑拖到汽车轮子上。）

6、P6（西瓜）这次可以藏在哪里？为什么？（再请幼儿上前来操作）一起说说“小黑藏在哪里？（我藏在西瓜的瓜籽里）。”

7、P7（盒子，有很多小黑）小黑说每次都被小朋友找到了，这次它要找一个谁也找不到的地方，想想小黑会藏在哪里？（请幼儿自由结伴猜猜、说说）

（拉开遮挡部分）原来小黑和它的好朋友藏在了一起，为什么不知道哪个是小黑了呢？（因为它们长得一模一样。）

三、完整讲述故事，熟悉故事的主要内容。

1、师幼一起讲述故事“让我们一起看看小黑都躲到了哪些地方？”

2、讨论：“故事里的小黑藏在了那么多的地方，它藏在了哪里？”“如果你是小黑，还会躲到哪儿呢？”

四、游戏“藏小黑，再找找别人的小黑。”

1、请把你的小黑藏在一个不容易被人发现的地方，然后再去找找别人的小黑。

2、说说你是在哪里找到的小黑？（幼儿藏小黑，幼儿找别人的小黑，说是在哪里找到的。）

捉迷藏课件【篇5】

【设计思路】

“捉迷藏，一个捉来一个藏”，这是最简单的游戏，也是全世界的孩子都喜欢玩的游戏。《小黑捉迷藏》这本绘本，就是结合了孩子们最喜欢游戏的一本书，它是一本让孩子们翻开第一页就会迫不及待地往下翻到最后一页的书。这更是一场惬意的旅行，跟着小黑率性的步伐，孩子们去发现世界的丰富多彩。每一个画面，每一个场景都带给小黑和我们无限地想象，如：小黑和小鱼、泡泡、车轮、水果等做游戏的画面，让孩子们尽情发挥想象力，感受自由和快乐。小黑就像我们的孩子一样，对世界充满了好奇，对生活充满了期待。在设计这个活动时，我结合了小班的幼儿的阅读特点，比如喜欢颜色鲜艳的画面，喜欢特点鲜明的形象，而小班幼儿阅读往往又不注重观察图画细节，所以设计了师生共同阅读，引导幼儿仔细观察绘本画面，体验阅读、观察、发现的乐趣。同时在阅读的过程中学习句式完整表达，丰富经验，在阅读中感受语言的美好意境。最后以游戏的形式开展活动，培养孩子们的思维能力、观察能力，还寓教于乐，学会大胆表达自己藏在哪里。

活动设计分为四个课时完成，本次活动为第一课时，活动重点是仔细观察画面，在阅读的过程中享受发现的乐趣，难点是能用“小黑藏在XXX”的句式表达。

活动分为四个环节完成：

第一个环节：运用出示小黑策略，激起幼儿参与活动的兴趣，引出主题；

第二个环节：运用导读大书重点画面策略，观察、寻找小黑躲藏的地方。

第二个环节：运用自主阅读小书策略，培养幼儿自主阅读的能力和习惯，继续熟悉绘本内容。

第四个环节：运用游戏策略，利用场景，体验游戏的趣味性。

活动目标：

涉及核心经验

1、运用多种方式阅读，在观察画面细节的过程中享受发现的乐趣。（运用多种方式的阅读，会仔细观察画面细节。）

前阅读——阅读内容的理解与表达

文学想象——再造文学作品的想象

2、会用“小黑藏在XXX”的句式讲述自己的发现。

3、在游戏中体验“捉迷藏”的快乐。

活动准备：

教师材料：教学大书《小黑捉迷藏》

场景设置：三张桌子，若干道具草和树

幼儿经验准备：会玩“捉迷藏”的游戏

活动过程：

一、神秘地出示小黑，引发幼儿的兴趣。

出示小黑，引发幼儿兴趣。

师：今天请来了一个好朋友，一起来看看它是谁？在哪呢？不好意思出来，我们一起找找吧！（引出小黑）

激起幼儿参与活动的兴趣，引出图画书《小黑捉迷藏》

二、师生共同阅读绘本，享受在阅读中发现的乐趣。

1、出示大书，阅读封面：

师：小黑最喜欢玩捉迷藏的游戏，我们一起找找看它藏到哪里去了？（原来藏到一本大书里面了）我们一起去找找吧！

唤起儿童阅读封面、封底策略，猜测图画书内容的已有经验

2、重点介绍比较难理解的画面信息

师：公园里，草青青，小黑小黑在哪里？（小黑小黑藏在草丛里）仔细看看，还有谁和小黑在捉迷藏？淘气的小黑又躲到哪里去了？（小黑藏在泡泡里）天空中，谁和小黑一起捉迷藏啊？如果你是小黑，在天空中，感觉怎么样？小黑跑的太快了，一头扎进了哪里呀？（小黑藏在玻璃珠里）你们一眼就发现了，真厉害。小黑说它要藏在一个你们都找不到的地方。

师（小结）：（阅读封底）啊，原来小黑藏在这里，和许多颜色宝宝在一起。小黑真会捉迷藏，藏了好多地方，你都找到了，而且都用完整的句子讲出来了，真厉害！

观察与寻找的策略导读关键画面，帮助幼儿找出躲藏的小黑。

三、幼儿自主阅读，继续熟悉绘本内容。

幼儿自主进行阅读，能够边看书边小声讲述自己的发现。重点用“小黑藏在XXX”的句式完整讲述。师：小黑都藏在哪些地方了？来讲讲你们的发现！

自主阅读，培养良好的阅读习惯

2、小黑藏在那么多的地方都被你们找到了，如果你是小黑，一起来捉迷藏，你会藏在哪里呢？

大胆表达自己的看法

四、利用场景，一起玩”捉迷藏”的游戏，体验游戏的趣味性。

1、《小黑捉迷藏》真有意思，我们的小朋友也很厉害，一下就找到了小黑藏在哪里了。我们也一起玩玩捉迷藏的游戏吧！

体验游戏加深孩子的阅读理解

2、在游戏中，询问幼儿藏在哪里。引导幼儿用完整语言表达，如：我藏在桌子下。

迁移经验，激发幼儿的想象力

3、捉迷藏的游戏真好玩，我们一起再到外面操场去玩玩吧！

活动结束

活动反思：

这个活动是在小班下学期开展的，我们班的孩子活泼好动，思维活跃，语言表达能力也比较强，他们都喜欢新鲜有趣又神秘的事物，所以对此活动一直充满了兴趣。在整个活动的开展过程中，有如下亮点：

1、运用简短押韵、琅琅上口的语言引导幼儿。在师生共同阅读的过程中，重点引导幼儿仔细观察画面，运用已有的经验，完整地用“小黑藏在XXX”的句式说出“小黑”藏在什么地方。而在引导的过程中呢，我运用简短押韵、琅琅上口的语言来描述小黑捉迷藏的环境，如：花园里，草青青，小黑小黑在哪里？水果甜，水果香，小黑小黑在哪里幼儿根据老师的提问，一问一答，自然而然地完整说出“小黑藏在XXX”的句式。

2、语言的抑扬顿挫，语气的多变，吸引幼儿的注意，每个幼儿都热情地参与活动，一直保持着注意力集中。本次活动从开始到结束差不多有25分钟，幼儿全程积极参与，踊跃探讨。

3、情景化的游戏对幼儿的知识进行巩固和衔接，有动有静，抓住幼儿对捉迷藏的兴趣，亲身体验，并用完整句式来回答，促进目标的达成。整个活动轻松、愉悦、有趣，体现出学中玩，玩中学，从而获得有意义的学习价值。

当然在活动中，也有很多值得改进的地方。比如在观察有些画面的时候忽视了一些细节。在个别画面中我对幼儿的引导语言不够简炼，过于重复和啰嗦，提问方式缺乏有效性。在以后的绘本阅读中，教师还应引导幼儿通过多种方式对角色的心理产生兴趣，注意心理变化，会更加集中注意力的进行阅读活动，体验和享受阅读带来的乐趣。

捉迷藏课件【篇10】

大家好，今天我的说课是小班课程，题目《和小动物们捉迷藏》，下面我将从说教材、说教法和学法、说教学过程、教学延伸、说教学用具五个方面来对本课程进行说明。

一、说教材

《和小动物捉迷藏》是逻辑狗思维训练——我们的宠物下册第一课，该单元以“和小动物们做迷藏”为主题展开。

本课是以图片的形式展现给幼儿的，图片色彩艳丽、卡通动物造型，能激发幼儿的兴趣，特别是智力魔板，游戏性很强，适合幼儿的年龄特点，教材的主要理念是通过幼儿的观察、对魔板操作、思考而找出图片中的小动物并用用语言来表达出来，以此训练幼儿的语言表达和幼儿的思维能力。

结合本单元教学要求和本课的特点，依据《纲要》中为幼儿提供：敢想、敢说、敢做，我将本课的教学目标确定为：

1、学习以客体为中心，认识和区分前后、里外。

2、学习正确使用方位词：前后、里外，能用方位词正确完整的表述。

3、通过教学活动发展幼儿的观察力。

教学重点：“以客体为中心认识”前后、里外。

教学难点：能用方位词前后、里外完整表述。

二、说教法和学法

科学合理的教学方法能使教学效果事半功倍，达到教与学的和谐完美统一。基于此，我准备采用的教法是导入游戏法、游戏法可以调动幼儿积极参与的兴趣，目的是让幼儿在玩中学习，在操作的体验中感知。充分发挥幼儿的主体作用。

学法上：主导思想是以游戏的方法，调动幼儿积极主动、自主操作、探究。具体的学法是观察法、操作法、检验法。让幼儿养成自我操作、自我检查，认真做事的好习惯。

三、说教学过程

为了完成教学目标，解决教学重点突破难点，课堂教学我准备按开始部分、基本部分、结束部分三个环节展开。

一、开始部分

（一）游戏导入：“今天有许多小动物来到我们班，小朋友想看看它们是谁吗？可是小动物很调皮，跟我们玩起了捉迷藏，我们一起找找它们吧！ ”教师提出要求：找到动物的小朋友要记住你是从哪里找到它的，一会告诉老师和小朋友。（ 以游戏导入可以激发幼儿参与活动的兴趣）

（二）请幼儿说说你是从哪里找到小动物的

请找到XX的小朋友说一说，你是从哪里找到XX的，然后放回原处，让其他小朋友看。

二、基本部分（落实基础，整体感知）

（一）出示图片，引出主题

导语：安娜也和她的宠物在玩捉迷藏，老师把她们的照片带来了，小朋友想不想看？

安娜一共有6只小动物，她只找到了小乌龟。乌龟在萝卜的后面，在菜地里边。

（二）教师引导幼儿观察，并说出方位词

导语：我们帮安娜找找其他5只小动物藏在哪了吧！

（此环节是引导幼儿学习观察图片，引出方位词：前后、里外。教师说出图片中的乌龟在萝卜的后面，在菜地的里面，引导幼儿说出其它的动物在什么地方，调动幼儿自主观察和思考，锻炼幼儿的观察力和语言表达能力，以此解决教学重点。）

（三）教师总结

1 、一共有6只小动物，和小朋友一起数数是不是全部都找出来了。

2 、它们分别藏在什么地方。

三、结束部分

（一）教师示范操作

导语：安娜想考一考我们小班的小朋友，给我们准备了一份小作业，看看小朋友们自己能不能找到小动物。

教师：这是小白兔，小白兔藏在哪了呢？在笼子里面大树下面，它旁边圆片的颜色是绿色的，就从小篮子里拿一个绿色的圆片贴在小兔的旁边。（可再示范一遍）

幼儿积极主动的操作，使幼儿处在积极观察思考的思维体验中，并说出观察的结果，因而能使幼儿在体验中加深理解，进而解决了教学难点。

（二）幼儿操作，教师个别指导

（三）教师总结幼儿操作结果 教师给予肯定。

四、活动延伸

让幼儿思考自己现在坐在哪里呢？怎样用前后、里外表述呢？

让幼儿明白以自己为中心，自己所处的方位。加深以“客体为中心认识和区分前后、里外”的理解。

五、教学版面设计

好的版面设计，它形象直观，使幼儿易于幼儿理解教学内容，激发幼儿参与教学活动的兴趣，积极思考，教师的情感传递给幼儿使师生情感产生共鸣，进而使教学活动展开顺利。

以上，我从教材、教法学法、开始部分、基本部分、结束部分、活动延伸、教学版面等方面对本课进行了说明，我的说课到此结束，谢谢各位老师。

捉迷藏课件【篇12】

教学意图：

《捉迷藏》的结构简单，内容贴近幼儿生活，能激发孩子欣赏和学习的热情，很适合小班孩子欣赏、学习。

活动目标：

1、尝试从整体到局部观察常见的水果，提高观察能力。

2、乐于用语言表达自己的观察和发现。

活动准备：

1、已有经验：

幼儿对常见水果的名称、形状、颜色等有初浅的认识。

2、材料准备：

（1）教师用具：

①自制大图书。

②用纸盒做成“苹果的家”，里面装入红、黄、绿苹果。

③用多张大图书的页面遮挡苹果、梨、香蕉的图片，在遮挡的页面上挖洞，越往后洞越大，露出的水果面积越大。

（2）幼儿操作材料：

①用黑色手工纸做成苹果、梨、香蕉的影子，放于幼儿身边的桌子上。

②用透明塑封纸做成的苹果、梨、香蕉，藏于大图书内的信封里，多种颜色的底板纸。

③活动室一角布置成“水果乐园”。

活动过程：

寻找苹果、梨、香蕉的影子激趣导入

师：今天我们要一起来阅读一本大图书，书的名字叫《捉迷藏》。我们一起玩捉迷藏的游戏。（展示大图书中苹果、梨、香蕉的轮廓图。

师：小一班的宝宝们，我们是苹果、梨、香蕉。我们的影子已经在你们的桌子上了，快来找出我们的影子吧。

一、交代任务

师：原来是苹果、梨、香蕉要和我们一起玩捉迷藏的游戏。现在请你走到桌边，看一看、想一想桌子上的影子是谁的，然后把它送到苹果、梨、香蕉的家里。

1、幼儿操作，老师观察指导。

幼儿将影子贴到大图书相应轮廓图的下方。

教师观察指导要素：

（1）幼儿能否按照外形把水果影子送至相应的地方。

（2）当幼儿匹配正确时，教师宜用提问帮助幼儿提升：这是什么水果的影子？它的形状是怎么样的？

2、教师小结。

（1）重点提问：你怎么知道这是苹果、梨、香蕉的影子？它们的形状是怎么样的？

（2）同步出示实物水果并小结：苹果的形状是圆圆的，梨的形状是一头大一头小，香蕉的形状是长长的、弯弯的。我们是根据形状找到了苹果、梨、香蕉的影子。

寻找苹果、梨、香蕉的颜色再次激趣。

师（模拟水果宝宝的声音）：没想到你们这么厉害，一下子就找到了我们的影子。我们再来玩一次吧。你们准备好了吗？

二、交代任务

师（出示塑封纸做的透明的水果）：这次水果们把自己的颜色藏起来了。你们想一想苹果、梨、香蕉是什么颜色的？把它们送属于自己颜色的家里吧。

1、幼儿操作，教师观察指导。

教师观察指导要素：

（1）幼儿是否将透明的水果送至与其颜色相应的颜色底板纸上。

（2）当幼儿匹配正确时，教师用提问帮助幼儿提升：你为苹果、梨、香蕉穿上了什么颜色的衣服？

2、教师小结。

（1）当绿色没有幼儿使用时，重点提问：苹果宝宝有哪些颜色的衣服？你在哪里看见过不同颜色的苹果？

（2）有个别幼儿用到绿色时，重点提问：你在哪里用到绿色时，重点提问：你在哪里见过绿颜色的苹果？苹果宝宝还有什么颜色的衣服？

（3）出示“苹果的家”并小结：不同的水果有不同颜色。有些同种水果也会有不同的颜色。

寻找躲在门后的水果

第三次激趣。

师（模拟水果宝宝的声音）：你们一会儿就找到了我们的衣服颜色。我们还没有玩够呢，再躲起来。哈哈，这次有点难找哦。

三、交代任务

师：这次苹果、梨、香蕉躲在门背后，只露出一点点。我们来看看到底门后面躲着谁。

1、幼儿观察、判断，谁躲在门后。

（观察用多张大图书页面遮挡的苹果、梨、香蕉的图片。若幼儿看第一页就能判断出则最好，若不能判断出，就往后翻到第二页、第三页。越往后翻，露出的面积越大，判断难度越小。）

可能出现的情况：

（1）当幼儿猜出水果时，教师重点提问：你从哪里看出这是苹果、梨、香？

（2）当幼儿猜不出水果时，教师就再打开本一扇门，露出更大面积的水果局部，降低幼儿猜测的难度。

教师重点提问：你能根据颜色、形状猜出是什么水果吗？还有什么可帮助你猜出是什么水果？

教师小结：

看来要找出它们，我们要看得仔细一点、认真一点呢。

活动延伸：

师（模拟水果宝宝的声音）：你们的眼睛可真厉害，我们只露出一点点还是被你们认出来了。

师：活动室后面有一个“水果乐园”，现在我们去那里和更多的水果宝宝玩玩吧。

教学反思：

目标是让宝宝们在感受到游戏快乐的同时也学习很多知识。主要内容是我们的水果宝宝的影子和颜色藏起来了，启发我们的小朋友通过水果宝宝的不同形状找到自己的影子，同时也对于平时经验的积累找到水果的不同颜色。激发幼儿参与的积极性，给与了每位孩子的表述机会，真正体现了玩玩乐乐中学习了语言，在学习语言中体验快乐，在快乐的体验中增长知识。整个活动在欢快活跃的气氛中进行着，课后结束受到教师们的好评。

那只松鼠课件收藏九篇

教案课件是每个老师工作中上课需要准备的东西，每天老师要有责任写好每份教案课件。教案的编写应落实素质教育的要求和目标。想要深入了解“那只松鼠课件”以下是为你准备的相关资料，请将这篇文章添加到你的收藏夹随时查看！

那只松鼠课件 篇1

松鼠【学习目标】

1动情地读课文，感受生动的讲解和准确的语言

2了解松鼠的兴态特征和生活习性，激发学生关心和保护野生动物的兴趣。

【课前预习】

一、阅读说明文的步骤

1．抓住文题，弄清说明对象。

说明文的标题比记叙文的标题具有更强的提示性，往往直接交代说明对象，如《巍巍中山陵》《凡尔赛宫》等，从这些文章的题目上便可知说明对象。

2．抓住说明对象的特征，把握说明内容。

阅读说明文，只有把握文章中要说明的事物的特点，才能对作者的东西有一个清晰的认识。所谓“特征”，就是这一事物区别于其他事物的标志。如《人民英雄永垂不朽》一文开头用六个字概括了纪念碑的总体特征——“巍峨、雄伟、庄严”，然后围绕这一总体特征，说明了有关局部具体特征；而《巍巍中山陵》则扣住“巍巍”这个显著特征进行说明、描写。

3．弄清说明顺序。

事物的特点和本质是按照合理的顺序逐户表现出来的。说明文是根据对象本身的特点来安排描述顺序的，因此不同的对象使用不同的描述顺序。

4．掌握说明方法及其作用。

二、知识链接

【作者介绍】

布丰（1707-1788）是法国博物学家、作家和进化思想的先躯。他从小受教会教育，热爱自然科学。他用40年时间写成了36卷《自然史》。

这是一部博物志，包括《地球形成史》《生物史》《人类史》《鸟类史》《爬虫类史》《自然的分期》等部分，对自然界作了唯物主义的解释。

【科学小品文】

科学小品文也称知识小品或文艺性说明文。它运用散文的文体，即借助一些文学写作技巧，将科学内容生动生动地表达出来。

科技**是以文学的文体写作的，具有科学性、知识性、趣味性和娱乐性，使读者在文学欣赏中获得科学知识。

科技**一般短小精悍，通俗易懂，语言丰富多彩，形式生动。阅读这种文章可以激活思维，丰富知识，开阔视野，很受广大读这的欢迎。

【自主梳理】

一．给粗线字注音

驯良（ ） 矫健（ ） 帽缨榛子（ ）

橡栗（ ） 蛰伏（ ） 苔藓榉实（ ）

二．整体感知

松鼠有哪些特点？给人留下怎样的印象？（用文中句子回答）

【合作**】

1、从文中哪些地方具体可以看出松鼠的漂亮、驯良、乖巧，讨人喜欢？（找出并概括）

用了哪些说明方法说明的？（自己读课文，圈出大纲，分组交流，合作展示）

(齐读)表现松鼠某个特点的句子

（组员一）概括从哪个方面表现了这一特点

（组员二）运用了什么说明方法说明这个特点

2.本文以什么顺序显示人们逐渐喜欢松鼠？

3、比较下列两段文字，哪一段说明文字中的松鼠更“讨人喜欢”？为什么

a .《辞海》：松鼠亦称“灰鼠”，哺乳纲，松鼠科。体长20—　28厘米　。尾巴蓬松，16-24厘米长。体毛灰色，深棕色或红棕色，腹侧白色。

b . 玲珑的小面孔，衬上一条冒缨形的美丽尾巴，显得格外漂亮。尾巴总是翘起来，一直到头上，自己躲在尾巴下面凉快。

（从课文中找出相似的句子，阅读并欣赏，在书旁注释，分组交流，代人发言）

【学习感悟】

为什么作者能准确生动地描述松鼠的特征和生活习性？

作者笔下的松鼠为什么这么讨人喜欢？富有灵性之美？

这对我们有何启示？

【课后练习】

模仿课文，描述一个熟悉的小动物。仔细观察后，要用生动的语言解释。

【资料链接】

布丰在《自然史》一书中对马就有如下描述：“人类历来最了不起的征战，就是驯服了这种既傲气又烈性子的动物。它与人民一起分担战争的疲劳，分享胜利的荣耀；它容不得自己使性子，行事知所进退，不但听命于执缰者之手，似乎还可会其意，按感知来行事：

或奔突，或碎步。每一个动作，目的就是为了取悦——这动物全然忘我，只为别人的意志而活，甚至有**他人意愿的能耐，然后准确地落实在行动上。它善解人意，毫无保留地、全不拒绝地、全心全意地服务，鞠躬尽瘁，死而后已”。

《自然史》展示的艺术家的一种人生态度。他以异常平静，悠然自得的语言去歌颂大自然的一草一木，盈尺之内呈现着造物的尊严与灵性。

三、精读品悟

围绕“小松鼠那么可爱，你是从哪儿看出来的呢”展开谈话。随着学生的交流，教师相机从四个方面组织教学。

（一）外形的美丽

你觉得松鼠哪儿最美？引导学生抓住“玲珑”“美丽的尾巴”“毛茸茸”等词语体会松鼠的美丽。

采用个人读、赛读、齐读三种方法读出松鼠的美丽以及喜爱之情，之后出示课后填空题，学生填一填，读一读，积累语言，了解文章的写作顺序。

（二）动作的机敏

此段重点句是“只要有人稍微在树根上触动一下，它们就从窝里跑出来，躲在树枝底下，或者逃到别的树上去”，启发学生从“只要……就……”“触动”等词体会松鼠的机灵。

引导学生读出小松鼠的机灵劲儿。

（三）搭窝时的聪明

假如你就是一只小松鼠，你怎么向大家介绍搭窝的过程。

让学生上台展示，教师指导学生用上表示先后顺序的词语“先……再……然后……”。这样说，会让我们很清楚地了解松鼠搭窝的过程。

小结：看来，这些表示先后次序的词，作用还真不小呢。

集体读这部分，进一步认识连词的作用。

（四）吃食时的有趣

要知道吃什么？怎么吃？让学生模仿一下吃食的动作。然后围绕三个“它们”进行教学。

四、积累运用

创设情境，让学生扮成小松鼠，用第一人称的方法，创造性地介绍自己最可爱的一面。还可以把课外了解的知识融合进来。

教师引导：不光小松鼠可爱，其他小动物也非常可爱。前面大家用一句话说了说自己喜欢的小动物。现在你能像课文一样，写一段话来描绘这种小动物的一个特点吗？学生练笔，互相交流。

五、拓展延伸

课后大家可以办一张关于动物的手抄报，然后我们可以在学校宣传栏里办一次关于动物的专栏，让叔叔阿姨们都来看一看，他们一定会听到我们的心声——请保护动物。

那只松鼠课件 篇7

教学目标：

1、 品味文艺性说明文形象生动的语言。

2、 了解按照认识事物的客观规律进行说明的说明顺序。

3、培养学生热爱一切生命的情怀。

教学重点：

品味文艺性说明文形象生动的语言。

教学过程：

1、导入：同学们一定看过《人与自然》的节目吧，通过这个节目我们认识了不少动物。陈老师最喜欢的动物是熊猫，因为熊猫憨态可掬。所以我喜欢憨态可掬的大熊猫。你们最喜欢什么动物呢？你喜欢的动物最突出的特点是什么？请同学们用半分钟时间想想，然后采用“我喜欢 的 ”这样的句式把你喜欢的动物介绍给大家。（目的：激发学生的学习兴趣，同时训练学生运用形容词的能力）

看来同学们认识的动物还真不少。今天我们还要来认识一种动物——松鼠。

2、 过渡：松鼠是一种怎样的动物呢？为了了解松鼠，老师从辞典中查阅了一些资料。

通过幻灯片展示一段材料：

松鼠亦称灰鼠。体长20—28厘米；尾蓬松，长16—24厘米；体毛灰色、暗褐色或赤褐色，腹面白色。林栖。用树叶、草苔筑巢，或利用鸦、鹊的废巢。嗜食松子、胡桃等果实，有时食昆虫和鸟卵。年产1—4窝，每窝3—4仔。皮毛可制衣，尾毛可制笔。（说明：为了学习的目的，这段材料经过修改）

从以上这段文字中我们可以了解到松鼠的哪些知识？（明确：外形、生活环境、筑巢、吃的食物、生育情况、用途）

下面我们就对照着这段材料来学习课文《松鼠》。

（1）请学生大声散读课文《松鼠》，并谈体会：你喜欢材料中介绍的松鼠还是布丰写的松鼠？为什么？（目的：以学生的感受为主体，让学生自己去体会出课文的语言形象生动的特点。）

抓住文中的动词、形容词及修辞手法进行比较分析。重点分析课文的语言特点：拟人化的描写，生动形象，富有感情。）

学生边说我边板书，并通过板书总结松鼠的特点、简单地说明文章的说明顺序。

（明确：二者的目的是不一样的，并没有好坏之分。材料注重的是松鼠知识上的介绍，因此要求语言准确明了、简洁。而本文是一篇文艺性说明文，不仅让我们了解松鼠，还要让我们喜爱松鼠，和松鼠成为朋友，因此语言形象生动，极富情感。）

过渡：其实布丰不仅喜爱松鼠，他还喜欢自然界的很多动物，也写了很多的动物。（通过幻灯简介布丰）

组织学生阅读布丰写的其他动物的片段，进一步体会布丰的语言特点。

看一幅狼的图片，想一想说一说狼在人的眼中是怎样的形象？（明确：贪婪、狡诈、凶残等等。）联想有哪些和狼有关的成语？（狼狈为奸、狼心狗肺、狼子野心等）。通过幻灯片展示描写狼的片段，并请学生思考：片段中的狼是一幅怎样的形象？会让你联想到什么样的人？（孤独无助、象荒原上的流浪汉。这就是法国博物学家、作家布丰笔下的狼。布丰笔下的狼是可怜无助的，布丰让我们对狼现在的处境有了更深刻的了解。）

5、作业：阅读布丰其他写动物的文章，评一评它的语言好在哪里。

4、第六七自然段中的省略号，引发学生想像：假如你自己就是这只被俘虏的松鼠，那目光里饱含的是什么，脑子里会想些什么？

1、生读课文后三个自然段，思考：“我”为什么要“发誓回家后只字不提那只松鼠”？

2、“我”为什么“心里的一块石头落了地”？

3、如果你是文中的小女孩，听了“爸爸”放松鼠 你会想些什么，又会说些什么呢？

通过学习本课，你明白了什么?

芦叶船课件 篇4

《芦叶船》 教学设计

教材分析：

玩是儿童的天性。但是玩什么却千差万别。在孩子的眼里，蓝天、大海、山、水、花、草，一草一木都可以成为孩子的玩具。然而，作者笔下的童年欢乐则来自于小小的芦叶船。写得形象鲜明，生动感人。描述了孩子们用芦叶做成一只只小小的芦叶船，这种快乐远离城市的喧嚣，是一种自然的从内心流露出来的朴素与真挚。作者那种对童年生活的眷恋，对芦叶船的喜爱，自然流露笔端，文章的结尾，则给人无尽的遐想，含蓄而深刻。

课前准备： 学生准备，：自制小船，搜集有关江南地理特点及河道、芦叶船的相关资料。

教师准备：课件。 课时安排：二课时 教学过程：

第一课时

课时任务：

正确认读并会写十一个要求会写的生字，并掌握相关的词语，联系上下文理解“桅杆、舢板”等词语的意思。正确、流利、有感情地朗读课文。

一、情境导入

在江南水乡，这里风景如画，河道纵横交错，一开春儿，便芦苇丛生。聪明的水乡孩子都爱玩一种自制的玩具，那就是——芦叶船。（板书：芦叶船）

二、预习检查

【设计意图：检测学生预习情况，逐步培养学生学习语文的习惯，提高自学能力；引导学生初步掌握生字新词；指导学生多层次地朗读，在朗读中感悟，为更好理解课文内容做铺垫。】

三自读自悟

1、默读课文，说一说课文课文讲了关于芦叶船的什么事？芦叶船给作者的童年生活带来了什么？

2、想一想，课文哪些地方给自己留下了深刻的印象？再把那部分语句画出来，多读几遍，

3、小小的芦叶船带给作者儿时许多快乐。下节课，让我们继续学习《芦叶船》。

【设计意图：熟读课文不仅有利于学生了解课文大意，而且为理解课文奠定了基础。】

（出示感悟题：默读课文，课文哪些地方给自己留下了深刻的印象？再把那部分语句画出来，结合重点词语把自己的感受写在词语旁边的空白处。再带着你的体会读一读。

2、小组交流读书体会。

3、全班交流，品词析句，指导朗读。 交流预设： 预设：

——玩的地方美。

1、大阔叶折成大篷船，小窄叶做成小舢板；有时还把三五片芦叶叠在一起，做成三桅杆、五桅杆的大船。我们把船做好后，在船底吐上一口唾沫，跑到小木桥上，把芦叶船往河中央轻轻地 一扔，保险翻不了船。 指名读，思考并回答：小小的芦叶能制作出这么多种的船，而且下到水里翻不了船，你感觉这是一群怎样的孩子？

2、船一下水，便顺着风儿开走了。我们就用芦叶卷成喇叭，“呜啦呜啦”地吹奏着，欢送他们远航。

展开自己的想象，用自己的语言描述一下“我”和我的小伙伴们当时心里会怎么想？他们彼此会说些什么呢？教师可引导学生一边理解一边有感情的朗读。

3、齐读这一自然段，感受孩子们制作芦叶船时的快乐。 ——玩的玩具制作得美。 第三自然段。

通过一系列具体生动的描写，详细回忆了作者和小伙伴们玩芦叶船时的情景。表现出孩子们通过自己的巧手创造出一只只各具特点的芦叶船，充满着个性与创造，更充满了智慧。

——玩儿的过程美。 第四自然段。

孩子放了芦叶船却还依然牵挂着它，总喜欢在第二天回来找寻。从孩子们的手艺不同，可以看出孩子们都非常地心灵手巧。他们还把找不到的芦叶船想象为“远航”，把能找到的称为“进港”，显得非常地有童真童趣。

第七自然段。

在这一段，让我们看到了小小的一个三桅杆的芦叶船竟然真的乘风破浪地开走了，真的是非常令人惊叹的。

这里，通过对表兄说话的语气和娴熟和动作的描写，使我们感受到了生活在江边的孩子的活泼、聪明与自信。

通过交流，通过感悟课文的内容，你现在最想说的是什么？ 实际，无论玩什么，在玩耍的过程中，都会遇到很多这样那样的问题，如芦叶船搞不好会漏水、重心不稳会翻、芦叶折压不当小船还会散„„要想在玩耍中玩得精彩、漂亮，是需要智慧与耐力，甚至运气的。

【设计意图：抓住词句引导学生理解课文内容，并认真品味精美的词句，学习描写的方法。培养学生自学习惯为终身学习奠定基础培养学生的口语表达能力及拓展知识面。】

二、拓展阅读。

1、课文把怎样做芦叶船、怎样玩芦叶船写得非常生动。你最喜欢玩什么？能用你的笔告诉大家吗？

2、课外阅读：故乡的芦苇

【设计意图：学生的阅读能力水平的提高不是一朝一夕的事情，必须天天坚持、课课坚持，天长日久，定会有效果，因此，我们老师一定要每一篇课文都安排两篇阅读材料，逐步提高学生的阅读能力与水平。】

三、选择练习 1照样子，写词语。

浩浩荡荡（ ）（ ）（ ） 又惊又喜（ ）（ ）（ ） 2完成下列填空。

作者的家乡在（ ），那里（ ）特别多，有横的、竖的，像（ ）。一开春，河边就冒出许多（ ）来，孩子们用它做成了（ ），给我们带来了无限的快乐。

【设计意图：此次练习以字词为主，检验学生对字词的掌握及运用情况。第2小题是三个非常明显的比喻句，句子描写得都很生动形象，要求学生能够体会这样写的好处，积累语句。】

（2）知道分子的大小，知道数量级的概念，记住分子大小的数量级．

（3）理解阿伏加德罗常数，记住它的数值和单位．

（4）会一些简单微观量的计算，如分子大小、直径等

（5）知道油膜法估测分子大小实验

教学建议

教材分析

分析一：本节简单介绍了分子动理论的第一个基本观点：物质是由大量分子组成的．要注意这里的分子与化学中提到的分子的含义是不完全相同的，这里把构成物体的分子、原子、离子等统称为分子．

分析二：油膜法估测分子大小实验是一个重要的实验，它巧妙地将微观的、不易测量的量转化为宏观的、可直接测量的量，能较好地培养学生解决问题能力，扩展学生分析问题的思路．在将解本实验时要注意实验原理的分析

分析三：阿弗加德罗常量是联系宏观和微观的重要桥梁，已知物质的体积和摩尔体积，就可以求出物质的分子数，；已知物质的质量和摩尔体积，就可以求出物质的分子数，；已知物质的摩尔体积，就可以求出该物质的单个分子体积；已知物质的摩尔质量，就可以求出该物质的单个分子质量．

教法建议

建议一：本节内容在初中已有相当好的基础，因此可以结合复习初中知识来讲解本节知识．另外还可以引入相关化学知识，使学生更易理解．

建议二：油膜法估测分子大小实验是一个重要的实验，有条件的学校最好能让学生自己动手做这个实验，以加深学生的分子大小的直观感觉．

建议三：围绕阿伏加德罗常数的计算，教师可以举几个例题，然后让学生自己动手计算几个相关题目．

教学设计方案

教学重点：分子大小的计算

教学难点：微观量与宏观量之间的联系

一、物质有大量分子构成

结合化学提出不同物体不同的分子组成，并且物理中此时提到的分子有别于化学中的分子，它包括分子、原子、离子等．

展示几个漂亮的分子模型，激发学生学习兴趣．

二、分子的大小

1、分子大小的测量方法

（1）显微镜观测

（2）实验油膜法估测分子大小

实验原理：将体积为的油滴到水面上，使其均匀地、尽可能地散开成很薄的一层，此时可以认为油分子一个挨一个紧密排成一单层油膜，油膜的厚度就是单个分子的直径，因此只需测出油膜的面积，就知道该油分子的近似直径

实验过程所用的酒精油酸溶液溶于水时，酒精溶于水，油酸形成单分子油膜．

例题：将1 cm3的油酸溶于酒精，制成200 cm3的油酸酒精溶液．已知1cm3溶液有50滴，一滴滴到水面上，酒精溶于水，油酸形成一单分子层，其面积为0.2 m2.由此可知油酸分子大约为多少？

解：一滴油酸酒精溶液含油酸体积

油酸分子直径约为：

三、阿伏加德罗常数

阿伏加德罗常数是联系微观和宏观的一个重要桥梁，其大小为每摩尔物质含有的微粒数（或12g炭12含有的炭原子数），即6.02×1023mol-1．

已知物质的体积和摩尔体积，就可以求出物质的分子数，；已知物质的质量和摩尔体积，就可以求出物质的分子数，；已知物质的摩尔体积，就可以求出该物质的单个分子体积；已知物质的摩尔质量，就可以求出该物质的单个分子质量

例题：已知地球到月球的距离是3.84×105km，铁的摩尔质量为56g，密度为7.9×103kg/m3，如果将铁原子一个一个地排列起来，从地球到月亮需要多少个铁原子？

Ａ、1.4×105个B、1.4×1010个

C、1.4×1018个D、1.4×1021个

答案：C

分析：本题可以先求出单个铁原子的直径：

所以需要的铁原子个数为：

另外，本题还可以从数量级上迅速判断出答案，由于地球到月亮的距离数量级为108m，而分子直径的数量级在10-10m左右，所以需要的铁原子个数在1018的数量级上，应选C选项．

四、作业

探究活动

题目：怎样测量阿伏加德罗常数

组织：分组

方案：查阅资料，设计原理，实际操作

评价：方案的可行性、科学性、可操作性

【教学方法】

讲授法、谈话法、演示法、实验法、讨论法

【教学过程】

（一）引入新课

教师活动：

创设情景 ：带一瓶香水到教室里面，打开盖子，让大家都闻到香味。

提问：大家想过没有“我们为什么会闻到香水的香味？”然后让学生进行讨论。总结：一切物质都是由分子构成的，而且分子在永不停息的无规则运动。

（二）进行新课

1、播放课件：通过油膜法实验估测分子的大小。

单分子油膜法粗测分子直径的原理，类似于取一定量的小米，测出它的体积V，然后把它平摊在桌面上，上下不重叠，一粒紧挨一粒，量出这些米粒占据桌面的面积S，从而计算出米粒的直径

d?VS?10注意：除一些有机物质的大分子外，一般分子的直径数量级为10说明，通常就以上面数值作为分子直径的数量级．

m，如果无特别

2、演示实验：

（1）把盛有二氧化氮的玻璃瓶与另一个玻璃瓶竖直方向对口相接触，看到二氧化氮气体从下面的瓶内逐渐扩散到上面瓶内。

（2）在两只装满不同温度净水的烧杯中，分别滴入一二滴红墨水后，红墨水在水中扩展的速度不同，热水快，冷水慢。提问:上述两个实验属于什么物理现象？这些现象说明什么问题？

总结：上述实验是气体、液体的扩散现象，扩散现象是一种热现象。说明分子在做永不停息的无规则运动。而且扩散现象的快慢直接与温度有关，温度高，扩散现象加快。

3、播放课件

1、介绍布朗运动现象的发现背景以及其定义

1827年英国植物学家布朗用显微镜观察悬浮在水中的花粉，发现花粉颗粒在水中不停地做无规则运动，后来把颗粒的这种无规则运动叫做布朗运。

2、介绍布朗运动的几个特点

（1）连续观察布朗运动，发现在多天甚至几个月时间内，这种运动一直在持续。所以说，这种布朗运动是永不停息的。

（2）换不同种类悬浮颗粒，如花粉、墨汁中的炭粒等都存在布朗运动，说明布朗运动不取决于颗粒本身。

（3）悬浮的颗粒越小，布朗运动越明显。颗粒大了，布朗运动不明显，甚至观察不到运动。（4）布朗运动随着温度的升高而愈加激烈。

3、分析、解释布朗运动的原因（结合课本中的图形进行解释）

布朗运动是悬浮在液体中的微小颗粒受到液体各个方向液体分子撞击作用不平衡造成的。但液体中许许多多做无规则运动的分子不断地撞击微小悬浮颗粒，当微小颗粒足够小时，它受到来自各个方向的液体分子的撞击作用是不平衡的。如教科书上的插图所示。

在某一瞬间，微小颗粒在某个方向受到撞击作用强，它就沿着这个方向运动。在下一瞬间，微小颗粒在另一方向受到的撞击作用强，它又向着另一个方向运动。任一时刻微小颗粒所受的撞击在某一方向上占优势只能是偶然的，这样就引起了微粒的无规则的布朗运动。

注意：

1、布朗运动是固体微粒的运动，而不是固体分子的运动，也不是液体分子的无规则运动。

2、固体微粒的运动是不规则的，课本图中并不是微粒运动的轨迹，而是每隔一段时间的位置的连线。

3、任何固体微粒悬浮于液体中，在任何温度下都会做布朗运动。

【总结点评】

教师活动：让学生概括总结本节的内容。请一个同学到黑板上总结，其他同学在笔记本上总结，然后请同学评价黑板上的小结内容。

学生活动：认真总结概括本节内容，并把自己这节课的体会写下来、比较黑板上的小结和自己的小结，看谁的更好，好在什么地方。

点评反思：总结课堂内容，培养学生概括总结能力。教师要放开，让学生自己总结所学内容，允许内容的顺序不同，从而构建他们自己的知识框架。其次教师还要在课后对这一节课的教学活动进行反思，以进一步改进教学。（体现新教改要求）

分子课件【篇3】

知道物体的运动和静止是相对的。

1.2过程与方法 ：

体验物体运动和静止的相对性;

能用实例解释机械运动及其相对性。

1.3 情感态度与价值观 ：

通过观察物体运动，培养学生观察、实验的兴趣和习惯，养成认真细心、实事求是的科学态度。

机械运动的定义，以及在研究机械运动时要选择合适的参照物。

运动和静止的相对性。

充分体会选择不同的参照物，物体运动情况是可以不同的。

【师】日常生活中，你都见过哪些物体是运动的，哪些物体是静止的?下面有几个运动的例子，想一想判断下他们是不是运动的根据是什么。说

①你从座位走到黑板前，这一过程中，你的什么发生了变化?

②有一辆汽车停在路边和在路上行使有什么不同?

③说天上飞的飞机是运动的，你根据什么?

【师】根据我们刚刚的几个例子，可以看出来，上述的几个运动的物体，他们的位置都发生了相应的改变，所以我们今天要学的机械运动，就是关于位置的改变。

①图中的那些物体是否在做机械运动?

②我们周围的树木，房屋以及教室里的桌椅是运动的吗?

【生】图中物体在做机械运动，树木和房屋不运动，依据是看物体的相对位置没有发生改变。

【师】整个银河系、喜马拉雅山、猎豹都在做机械运动，而树木、房屋以及桌椅也都跟地球自转，同时绕太阳公转，它们也在做机械运动。可见，机械运动是宇宙中最普遍的运动。

知识点：一个物体相对于另一个物体位置的改变叫机械运动。

A、松树苗一个月长高500px，属于生命活动，不是机械运动;

B、地球绕太阳公转，地球相对于太阳有位置的改变，是机械运动;

C、中日两国陆地距离平均每年靠近2.9m，陆地相对于原来的位置发生了改变，是机械运动;

D、成熟的苹果从树上掉下来，苹果相对于地面有位置的改变，是机械运动.

【师】刚刚说了机械运动是相对位置的改变，既然是相对的，就得找一个物体来比较比较。

把课本放在桌上，课本上放一把尺子，推动课本使课本沿桌面运动。

讨论回答：

选取课本作标准，尺子和课本是运动还是静止?

选择课本作标准，尺子和课桌是运动还是静止?

选择尺子作标准，课桌和课本是运动还是静止?

【师】刚刚的简单实验中，在同一个事物过程中，为什么选取的标准不同，得出的结论会有这么大的区别呢?

得出参照物的概念：

参照物：描述物体是运动还是静止，要看是以哪个物体做标准。这个被选作标准的物体叫参照物。

【师】有了参照物的概念后，我们再来看生活中几个常见的例子。如下图：

图中汽车和人的运动情况：选取地面做参照物，人是运动的;选取汽车做参照物，人是静止的。

从而我们可以得出：在讨论物体的运动和静止时，要看以哪个物体做标准，选择的标准不同，它的运动情况就可能不同。这就是运动和静止的相对性。

物体的运动是相对的。

C.物体是运动还是静止，与参照物的选择无关，对任何参照物而言结果都是相同的

从运动和静止的相对性和参照物及其选择的角度去分析，即可作出判断.运动是绝对的，静止是相对的，对运动状态的描述是相对的.研究同一物体的运动状态，如果选择不同的参照物，得出的结论可以不同，但都是正确的结论.

A.运动是宇宙中普遍的现象，地球及其它一切天体都在不断的运动和发展当中，该选项说法正确;

B.运动是绝对的，静止是相对的，是相对于不同的参照物来说的，该选项说法错误;

C.运动和静止都是相对参照物而言的，当选择的参照物发生变化时，对于物体运动状态的结论也可能发生变化，该选项说法错误.

故选A。

【例题】观察图中的烟和小旗，关于甲、乙两车相对于房子的运动情况，下列说法中正确的是( )

知识点：研究物体的运动情况时，首先要选取一个物体作为标准，这个被选作标准的物体叫做参照物.研究对象的运动情况是怎样的，就看它与参照物的相对位置是否变化.由此来突破此题。

所以甲车运动状态有三种可能：1、向右运动;2、静止;3、向左运动，且速度小于风速.

因为乙车旗向右飘，所以乙车只能向左运动，且速度要大于风的速度.

故选D。

【师】通过学习，可以发现：

一个物体的运动状态的确定，关键取决于所选取的参照物.所选取的参照物不同，得到的结论也不一定相同.这就是运动和静止的相对性。

依据是看物体的相对位置没有发生改变。

参照物：描述物体是运动还是静止，要看是以哪个物体做标准。这个被选作标准的物体叫参照物。

在讨论物体的运动和静止时，要看以哪个物体做标准，选择的标准不同，它的运动情况就可能不同。这就是运动和静止的相对性。

1.知道参照物的概念.

重点 什么是机械运动以及在研究机械运动时要选择参照物。

难点 运动和静止的相对性。选择不同的参照物，物体运动情况可能不同。

阅读课本第16、17、18页内容，认识物体运动形式的判断，完成下列问题：

1.宇宙中一切物体都在运动，机械运动是宇宙中的普遍现象.

2.一位同学从自己的座位走到黑板前，他的位置发生了变化，物理学里把物体位置的变化叫做机械运动.

3.你们肯定见到过许多静止的和运动的物体，请各举3例.

运动的物体：空中飞行的小鸟、疾驰的汽车、河道中的流水.

1.如果你的一位同学和你一起并肩向前走，你认为他是静止的还是运动的?站在路边的人又认为他是运动的还是静止的?

2.可见描述同一物体的运动情况，选择的对象不同，结论一般不同.在描述物体的运动时，被选作标准的物体叫做参照物.

3.试着描述图1.2-3和1.2-4各种情形中物体的运动状况，总结一下选择参照物的方法技巧.

1.不要用物体本身作为参照物，参照物理论上可以任意选，但不是乱选，参照物选得恰当更容易判断物体的运动状态.

2.没提到参照物时，一般是以地面或地面上静止不动的物体为参照物，如桥梁、路边的树木、建筑物等.

3.运用参照物，判断物体的运动情况，具体方法如下：

①确定研究对象，即明确要判断哪个物体是否运动;

②选定参照物，即假定一个物体不动;

③看被研究的对象相对于参照物的位置是否变化，若位置有变化，则被研究的物体是运动的;若位置无变化，则被研究的物体是静止的.

1.下列说法中各是以什么作参照物的.

(1)坐在船上的乘客是静止的.

乘客是静止——参照物是 船.

(2)“小小竹排江中游，巍巍青山两岸走”.

竹排在江中游——以江岸(青山)作参照物;

青山在走——以竹排为参照物.

(3)月亮从云中钻了出来.

月亮钻了出来——参照物是 云 .

2.坐在汽车里的乘客、司机和路旁的孩子们有如图所示的对话，以下分析正确的是(C)

1.判断一个物体的运动，能选择的参照物不止一个，但选择不同的参照物，得出的物体的运动状态不一定相同，所以物体的运动和静止具有相对性.

2.航天飞机在太空与宇宙空间站对接时，两者在空中飞行的速度大小和方向必须相同，此时两物体间彼此处于相对静止状态.

1.在第一次世界大战的空战中，一名飞行员发现自己的机舱有一只“小虫”在飞来，于是一把抓住，一看才发现是一粒正在飞行的子弹!我们知道徒手抓住正在飞行的子弹一般是不可能的，那么这位飞行员为什么能抓住呢?

解：这颗子弹飞行的速度大小、方向与飞机飞行的速度、大小方向(飞行员)相同，子弹与飞机(飞行员)保持相对静止，所以飞行员能抓住这颗子弹.

2.观察图中的烟和小旗，分析甲、乙两车相对于房子的运动情况：

乙车相对于房子的运动情况：①可能静止;②可能向右运动;③可能向左运动，但运动速度小于风速.

运动具有速度和方向，围绕子弹和飞机运动的速度和方向进行分析.

1.我们通常所说的“太阳东升西落”，是以谁为参照物呢?地理学科中所说的“地球绕着太阳转”又是以谁为参照物呢?地球同步卫星与地球一起在做同步运动，如果以地球为参照物，地球同步卫星是运动还是静止?

2.“刻舟求剑”是人人皆知的典故.郑人之所以没有通过“刻舟”而求得剑，是由于他不懂得运动和静止的相对性的物理知识所致.

B.所谓参照物就是我们假设不动的物体，以它作为参考研究其他物体运动情况

C.选取不同的参照物来描述同一物体的运动状态，其结果可以是不同的

D.研究物体运动，选择地面做参照物最适宜，因为地面是真正不动的物体

4.空中有甲、乙两架直升机.甲机中的飞行员看到乙机向上运动;乙机中飞行员看到甲机向下运动，同时看到地面向上运动.则相对地面，甲直升机向 下 运动，乙直升机向 下 运动.甲直升机运动得快.

5.在我国古典小说《镜花缘》中有这样一句话：“吉岁一阵大风，把我院一口井，忽然吹到篱笆外去.”

说这句话的人和相信这句话的人，在刮大风前是以地面为参照物的，在刮大风后又是以篱笆为参照物的.

一般人不相信一口井会被大风刮到篱笆外去，因为他们是以地面为参照物的.

分子课件【篇4】

1. 知道一些常见的天然材料和人造材料。

2. 初步能区分常见物品中使用的天然材料和人造材料，知道生活离不开材料。

1. 主动搜集关于新材料的信息。

2. 懂得动手制作新材料的一些方法。

1. 乐于与人合作。

2. 意识到人类为了满足自身的需求，不断在发明新材料。

3. 增强对新事物的敏感性，激发创新意识。

二、重点难点：

使学生知道生活中各种各样的材料在总体上可分为天然材料和人造材料两类，并意识到人类为了满足自身的需求，不断地发明新材料。

教师：对身边具有代表性的材料进行收集，制作“塑料”的材料(酒精灯、烧杯、牛奶、醋、勺子等)。(课前每小组材料全组装好，放置在小组桌面中间，把纱布也是先扎在烧杯口，)

导入：波波等几位好友一起到妍妍家做客。波波说“真皮沙发真舒服”，彬彬说“难道还有假的皮沙发吗?”。谁说的对?你怎么来区别呢?真皮沙发的材料来自动物，仿皮沙发的材料来自人造皮革。这是存在的事实，今天我们来通过学习了解天然材料及人造材料的区别。

(目的：引入天然材料和人造材料概念，引领学生对身边材料的观察与思考，从而引入课题。)

描述：这是我们人类的远古时代，我们看看古人生活和劳作的情景：炉子用石头砌成，器皿是用黏土制成的陶土罐，锤子用石块、绳子、木条组合起来，捕鱼船来自粗大植物的树干，手里拿的武器用木棍等加工而成，衣服和帐篷则是来自动物皮毛，制作的生活、生产用品材料全部是存在于自然环境中的天然材料。

思考：古人用这些材料制作生活用品，这些材料来自哪里呢?

学生讨论汇报：

归纳：存在于自然环境种的材料是天然材料，如木材、岩石、粘土、动物皮毛、棉花、蚕丝、石油等。

学生观察：天然材料可以制成很多我们现代人的生活用品，看看用哪些天然材料制作了生产、生活用品?同时指导学生填好记录表。

目的：帮助学生初步建立起天然材料的概念，引导学生关注材料的发展情况。

归纳：古人用黏土、树木、骨头、毛皮以及岩石来建筑、制衣、炊厨、制造狩猎武器等，但还不知道如何去改变他们所发现的天然材料，许多世纪以后，人们发现了通过塑造或切削它们而改变这些材料的方法。后来，人们进而发现了通过加热或化学反应去处理天然材料，所以有些用品虽然都来自天然材料，但其技术含量是完全不同的，让学生意识到人类为了满足自身的需要而不断地创新，因此从某种意义上讲，人类文明发展史就是对材料占有、认识、制造、使用与发展的历史。

(出示课件 部分天然材料的'用途：木材——做木制家具;黏土——制成陶罐;石油——提炼出的物质能合成橡胶和塑料;蚕丝——编织成丝巾;棉花——编织成棉质衣服;岩石——用来建造房屋。)

材料：出示牛奶、食醋、勺子、烧杯(或小锅)、酒精灯、石棉网、塑料汤匙、纱布、碟子。

今天我们也来自己动手用做人造材料吧。请同学们按照提示一步步的操作。

实验步骤:

1、将盛着牛奶(约100毫升)的烧杯(或小锅)放在酒精灯上加热。

2、不停搅拌，在沸腾之前取下来。在这同时可以加入一些色素。

3、将一汤匙食醋倒入牛奶中，均匀搅拌后，等待冷却。

4、过一段时间，牛奶冷却到白胶状时，用旧长丝袜做筛子，盖住烧杯将牛奶混合物倾倒到碟子中，过滤冷却好的牛奶。

5、把过滤出来的物质用塑料汤匙弄平。

6、用过滤出来的物质放在小器皿里，制作你喜欢的小动物。

7、将制好小动物放置在阴凉的地方，几天后变成了硬硬的“塑料” (要放足够的时间)。

(目的：让学生经历天然材料被加工成新材料的过程。虽然学生并不理解其中所发生的化学反应，但通过制作过程，学生能认识到有些材料经过处理后会生成新材料，从而初步形成人造材料的概念。)

汇报交流调查结果：展示在大屏幕上。让学生把自己的调查结果与同学交流分享。

讨论：

1. 为什么人们要用人造材料代替天然材料?

2. 天然材料与人造材料各有什么优点?

(目的：通过调查活动，学生会发现生活离不开材料，人造材料的使用量大大超过天然材料。使学生意识到人们为了改善自己的生活，不断发明和制造新材料，人造材料具有许多天然材料不可替代的优良性能，并让学生学会辩证地看待事物。)

粉笔、放大镜、水、高锰酸钾、酒精、玻璃管、铅块、钩码、烧杯、实物投影仪、各种不同物质的分子结构模型图片、模拟分子间作用力的课件。

教学过程

一、导入新课

师：从这节课开始，我们将进入第七章的学习。请同学们将书翻到23页，请一位同学将导语朗读一遍。

从本节课开始我们将学习与微观粒子和宏观宇宙有关的一些现象、理论和方法。这节课我们首先来探究微观的世界，学习“

一、走进分子世界”。

二、学习探究微观世界的方法，了解分子模型的主要内容

1．介绍模型法。

师：从很多现象我们可以判断出物质都是由很小的微粒组成的，但是物体内部的微小结构肉眼无法直接看到，我们应该怎样进行研究呢？科学家们找到了一个方法：观察现象——建立模型、假说（相当于猜想）——收集证据或进行实验进行验证检验——确认或建立新的模型（假说）。

2．下面我们也借用科学家的方法一起来认识物质的结构。（1）观察现象。

观察1：用素描炭笔在纸上画一条线，直接展示，问：细线是连续的还是断开的？（连续的）

再用放大镜观察，通过摄像头投影，问：细线是连续的还是断开的？说明了什么？（断开的，甚至可以观察到细小的颗粒。说明细线是有很小的颗粒组成的。）

观察2：展示一杯染成红色的水，问：水时连续还是断开的？（连续的）再用吸管吸取少量的水，一滴滴的挤出，问：水滴是连续还是断开的？（断开的，水能够被细分，说明水

1是由很小的颗粒组成的。）

观察3：打开酒精桶的盖子，扇一扇，待学生闻到气味后问：每位同学都能闻到酒精的气味，说明酒精气体是否可以被细分？（能够被细分）再问：进入你鼻腔的酒精气体的微粒是很大还是很小？

（闻见酒精的味道，说明酒精气体已经进入了人的鼻腔，每一位同学都闻到了，并且肉眼看不见，说明酒精气体是由很小的微粒组成的。）

（2）建立模型。

师：刚才我们分别观察了固态的素描笔留下的细线、液态的水和气态的酒精气体，发现它们可以被无限细分，由此我们提出一个猜想、假说（模型）：物质是由很小的微粒组成的。

师：在把物质无限细分的过程中，物质的种类没有发生变化，即没有变成新的物质，也就是说物质的化学性质没有发生变化，在科学中，像这种保持物质化学性质不变的最小微粒叫做分子。有了分子的概念后，刚才的猜想、假说（模型）可以修改为：物质是由分子组成的。

关于对“保持化学性质不变的最小微粒”的理解，我们还可以再打一个比方：我们学校可分为三个年级，每个年级由十个班构成，每个班级由50个学生组成，到这里我们再划分下去对学校的构成就没有意义了，因此学生个体是构成学校组织的最小单位。同样，物质划分到一定程度，就无法再保持物质的化学性质，这种能保持物质化学性质的最小颗粒称为分子。一杯水分下去是小水滴，小水滴分下去是小水珠，一直分到水分子，如果再继续分下去，就不具备水的性质了。

（3）检验和验证。

师：“物质是由分子组成的”这一观点我们如何来验证呢？必须借助于工具。科学家不断改进观察物质的手段和设施，发明了光学显微镜，可以看见微小的细胞；但最多可以观察到0.2μm的尺度，后来发明了电子显微镜，能够使人观察到10nm的物质结构，可以拍到一些较大分子的照片，例如图7-3；再后来人们又发现了扫描隧道显微镜，将观察精度提高到0.1nm，使人们观察到较小的分子和更小的原子，发现较大分子的内部结构，甚至能操纵较小的原子组成新的图案。

（4）确认假说（模型、猜想）。

师：①通过观察手段的不断改进，现在大家都确信：物质是由分子组成的。②采用“观察——提出假说——验证——确认或否定”这种模型法，对于研究物质的微观结构来说是很有用的一种方法。

3．讨论分子的大小。

（1）请同学们用刻度尺测量一下课本图7-3中一个碳化硅分子的直径（即相邻两个黑点之间的距离）。（约4mm）

图下的说明告诉我们，这个显微镜可以放大1500万倍。那么，同学们估算一下，一个碳化硅分子大约有多大？（2.7×10-7mm=2.7×10-10m）

（2）课文中还告诉我们水分子的直径、氢气分子的直径，请同学们找一找，是多少？（水分子直径4×10-10m，氢气分子直径2.3×10-10m）

科学研究发现，分子很小，一般分子直径的数量级是10-10m。想象一下，如果让2500万个人手拉手站成一行，那么这个长度将绕地球赤道一圈，而如果让2500万个水分子一个挨一个排成一行，那么这个长度就只有1厘米。

（3）由于分子很小，所以宏观物体中包含的分子的数量非常庞大。例如，1标准大气压下，1cm3（比划一下，一个食指端的大小）的任何气体中约含有2.7×1019个气体分子，让这些气体分子从容器中跑出，如果1秒钟跑出1亿个，你们猜需要多长时间？（约需9000年才能跑完）

三、探究分子间是否有间隙。

1．提出问题：现在我们已经确信物质是由大量分子组成的，有人提出一个问题：这些分子是一个挨着一个排列的然后组成宏观的连续的物体呢？还是每两个分子之间都有间隙，然后再组成一个空心的物体呢？

2．猜想、提出模型、建立假说：组成物质的分子之间有间隙（或没有间隙）。3．验证、确认或否定假说。

A.实验1：将高锰酸钾颗粒放入水中，将会看到什么现象？ ①实验器材：一包高锰酸钾颗粒和一个盛水的烧杯。

②实验要求：烧杯就放在桌子上既不要拿起，也不要晃动。高锰酸钾颗粒倒入水中的瞬间，立即开始观察。分工观察，一部分同学从烧杯的上方向下观察，另一部分同学从侧面开始观察。

③动手操作，观察现象。④交流讨论：

一问：实验中所看到的现象是什么？（水慢慢变成紫色。）

再问：水怎么变成紫色的呢？能不能具体描述一下水变成紫色的过程。（高锰酸钾颗粒沉入杯底，把一部分水染成紫红色，然后这紫红色慢慢向四周扩散开来。）

三问：再过段时间，烧杯中的水会怎样？（整杯水都变成紫色。）

四问：这个现象支持了上述哪个猜想？（微粒之间是有空隙的。）

五问：现在大家认为分子之间是有间隙的，你能结合现象解释一下吗？（构成水的微粒之间是有空隙的，构成高锰酸钾的颗粒进入水的空隙，使水慢慢变成紫色。）

六问：这个现象还说明什么问题？（高锰酸钾是由微粒即分子组成的；高锰酸钾的分子可以运动；水是由微粒即水分子组成的。）

B.实验2：等体积的水和酒精混合，总体积变小了。

教师演示：向一端封闭的玻璃管中注水至一半位置，然后再注入酒精，并在液面最高处做一记号。封闭管口，将玻璃管反复翻转，使水和酒精充分混合，观察液面位置。

实验现象：混合后水和酒精的总体积小于混合前水和酒精的体积之和。4．分析讨论：这个现象能够说明哪些问题？

（①水是有分子组成的；②酒精是由分子组成的；③水分子之间有间隙；④酒精分子之间有间隙；⑤水分子和酒精分子都能够运动。）

四、探究分子的运动规律

1．提出问题。

从刚才的两个实验中，我们发现高锰酸钾的分子可以运动，水分子和酒精分子也可运动。那么分子的运动是普遍现象吗？是部分物体的分子在运动，还是所有物体的分子都在运动？分子是自发的主动的要运动，还是被动的从动的在运动？分子是做有规律的运动，还是在做无规则的运动？分子的运动是短暂的，还是长久的永不停息的？

2．观察现象。

师：请同学们观察课本p.25图7-

4、7-

5、7-6所示的三个现象，你发现了什么？（红墨水的分子是运动的；香味分子是运动的，醋和酒精的分子是运动的。）

3．提出假说。

所有物体的分子都在自发的永不停息的做无规则运动。4．收集证据，验证假说的真伪。

（1）课件展示空气和二氧化氮气体的扩散现象。

强调：二氧化氮气体密度大，受重力作用应下沉，但事实上二氧化氮分子会向上运动；空气密度小，受重力作用应上浮，但事实上空气分子会向下运动。说明气体分子在自发的、无规则的运动。

（2）课件展示水和硫酸铜液体的扩散现象。

强调：硫酸铜液体密度大，受重力作用应下沉，但事实上会向上运动。水密度小，受重力作用应上浮，但事实上会向下运动。说明液体分子在自发的、无规则的运动。

（3）课件展示煤炭和墙角的扩散现象。

强调：时间越长。互相渗入越多，说明固体分子在自发的、无规则的运动，且永不停息。

（4）课件展示布朗运动。

强调：从花粉颗粒的永不停息的无规则运动我们可以间接推知水分子在永不停息地做无规则运动。

5．得出结论：一切物体的分子都在永不停息地做无规则运动。6．应用：列举日常生活中的其他的能够证明分子不停运动的事例。

水蒸发——潮湿的底面、衣服变干了，冰升华、樟脑丸升华，花香袭人等等。

五、小结：

（1）面对看不见也摸不着的微观世界，我们是利用什么方法探究的？（根据观察到的现象提出一种模型作为猜想，再搜集证据验证。）（2）利用这种探究方法我们了解到物质的微观构成是怎样的？（物质由大量分子构成）

（3）分子如何运动？一切物体的分子都在永不停息地做无规则运动。（4）有哪些证据能够说明分子在运动？（扩散现象、布朗运动。）

五、分子间的相互作用力

演示实验：把二个表面光滑的铅块相互紧压在一起

你观察到了什么现象？说明了什么？如果我继续用劲往里压，能不能把铅块压

短？ 这说明什么？生活中还有哪些现象说明分子间有相互作用的吸引力和排斥力？面对看不见也摸不着的微观世界，我们是利用：根据观察到的现象提出一种模型作为猜想，再搜集证据进行验证。利用这种探究方法我们了解到物质的微观构成是怎样的？

六、用分子模型解释固体、液体、气体的性质

知识梳理

1、用摩擦的方式使物体带电，叫做摩擦起电。

2、被丝绸摩擦过的玻璃棒所带的电荷称为正电荷（＋）；

被毛皮摩擦过的橡胶棒所带的电荷称为负电荷（－）。

3、同种电荷相互排斥，异种电荷相互吸引。

分子课件【篇6】

关注学生，营造宽松、民主、和谐的教学氛围。以学生为主体，师生互动为原则，精心创设问题情景，提供探索途径，引导学生思维、讨论，在讨论中探究获得知识，发现规律，掌握方法和发展能力。

“运动的描述”是“运动和力”的第一节，这一节看似简单，但它却深深影响运动、运动和力、机械能的学习，因而理解本节的内容对后面的学习起着重要的作用。

知道参照物的概念，知道物体的运动和静止是相对的。

体验物体运动和静止的相对性，能用实例解释机械运动及其相对性。

认识运动是宇宙的普遍现象，运动和静止是相对的，建立唯物主义世界观。

在课程标准的指导下，根据本节的内容及特点，采用讨论探究的方式进行。教师逐步深化提问，学生分析、论证、归纳得出结论，而后实例分析应用来使三维目标得到落实。

提问：生活中哪些物体是运动的？哪些物体是静止的？

这一问题与学生生活联系很紧，学生人人都能举出很多例子。教师选择几例记录。

这个问题激起学生的心里冲突而使学生主动思考，叙述各自的看法，讨论，而后明确：运动是宇宙中的普遍现象。

讨论探究②：你们刚才所举例子中说有的物体静止，有的物体运动，你是如何判断的？

由于物体的运动、静止是学生提出来的，问他们是如何得来，再次引起学生的思考、讨论，慢慢分析得出是通过看这个物体所处的位置是否改变的方法得来。

这样引起学生再次思考、讨论，得出结论：物体位置是否变化是相对于某个物体（标准）的，由此得出参照物的概念。

讨论探究④：行驶汽车中坐着一位乘客，请你们描述乘客是运动的还是静止的？

这里学生表述各自不同的看法，但经过讨论，分析得出：物体的运动和静止是相对的。

讨论探究⑤：刚上课时，大家所举的运动和静止的例子现在你怎样看？应如何完整的描述？

学生进一步的讨论分析，准确描述了物体的运动。

提问：这一节课你对“运动的描述”有了哪些认识？让学生归纳叙述本节的主要内容、判断方法，使学生对本节内容形成知识体系。

本节课由讨论探究的方式进行，学生人人参与，兴趣极高，不知不觉中完成了课程标准的三维目标。通过让学生观察身边熟悉的现象，探究物理规律，培养了学生的探究精神。活跃了课堂气氛，创造了一个良好的学习场所。在课堂中教师不再是一个主讲者，而是课堂教学的参与者和组织者，教师和学生一起去感觉、认识、探索、分析、概括，和学生建立起了良好的、平等民主的师生关系。重视了学生间的交流合作，加强了学生间友好相处的心态。充分体现了物理教学“从生活走向物理，从物理走向社会”“注重科学探究，提倡学习方式多样化”的教育理念。

教学过程：

引入新课

我们生活在物质世界中，我们的周围充满着物质：水、空气、石头、金属、动物、植物等都是物质。而对于物质是怎样构成的，这一古老课题，很早就有过种种猜测，有的主张万物之源是“气”，有的主张万物之源是“火”。公元前5世纪墨子提出的物质的最小单位是“端”，公元前4世纪古希腊的德漠克利特认为宇宙万物，是由大小和质量不同的，不可入的，运动不息的原子组成。此后经过近20xx年的探索，直到17世纪末，才科学地认识到物质是由分子组成的。

进行新课

（1）分子和分子运动

①物质是由分子组成的，分子是极小的微粒。如果把分子看做球形，它的直径约10—10米，这是一个极小的长度，不仅肉眼看不到，即使用现代的显微镜也看不清分子。由于分子极小，所以物体含分子数目大得惊人。通常情况下，1厘米3空气里大约有2。7×1019个分子，如果人数的速度能达到每秒数100亿个，要数完这个数，也得用80多年。

②构成物质的分子永不停息地运动着。由于分子太小，目前尚无法直接观察分子的行为，但我们可以从宏观的实验现象，来判断分子的行为。

演示实验：扩散现象

出示事先装有二氧化氮气体的广口瓶。说明瓶内红棕色的气体是二氧化氮。再出示一只空的广口瓶，其实瓶内装满了空气。将装有二氧化氮的瓶子向空瓶倾倒，这时看到红棕色气体流入空瓶，开始先沉到瓶底。此现象说明二氧化氮的密度大于空气的密度。

另取一只“空”瓶，按课本图16。1—2所示，将其倒扣在装有二氧化氮气体的瓶子上。这时要强调：装有密度较大的二氧化氮气体的瓶子在下，装有空气的瓶子在上，抽掉玻璃隔板，二氧化氮气体不会流进空气瓶内。现在我抽掉隔板，没有出现二氧化氮气体流动的现象，我们停一会儿再来观察瓶内出现的现象。

在等候期间，组织学生自己做墨水扩散实验：同学们课桌上的烧杯里盛有清水，大家不要振动桌子，保持清水平静。请大家向清水里慢慢的滴入一滴墨水，观察墨水的变化情况。滴入的墨水将下沉，在清水中留下了清晰的墨迹，过一段时间墨迹的轮廓变模糊，墨迹变淡，周围的水色变墨。

组织学生观察前面已做的气体扩散实验。此时空气瓶出现了红棕色，下面红棕色的二氧化氮瓶中颜色变淡。实验现象表明，二氧化氮气体进入了空气，空气进入了二氧化氮气体中。像这样，不同的物体在互相接触时，彼此进入对方的现象，叫做扩散。

扩散现象也可以发生在液体之间。请大家再观察一下刚才大家滴入清水的墨水，已经没有明显的墨迹了，整杯水都变黑些了，说明墨水和水也发生了扩散。为了说明液体的扩散现象，我们再来做个实验。（按照课本图16。2—3液体的扩散实验演示）现在我们看到无色的清水和蓝色的硫酸铜溶液之间有明显的界面，要观察到扩散现象需要较长的时间。为了节省课堂时间，几天前我就做了同样的实验，请大家看几天前的实验。（出示提前二天、四天、六天做的实验样本）这些实验告诉我们，静放的时间越长，界面变得越模糊不清，彼此进入对方越深。

固体之间也会发生扩散现象。有人用固体做过实验，将铅片和金片紧压在一起，放置5年后再将它们分开，可以看到它们相渗入约1毫米。其实在日常生活中，我们也观察到过固体的扩散。煤矸石有的原来就是石炭岩，由于长期地跟煤挤压在一起，它的内部也变黑了。

大量事实说明气体、液体、固体都有扩散现象，即使在日常生活中大家也能找到许多事例。例如，某同学擦点清凉油，周围同学就能闻到清凉油味。

扩散现象表明：一切物体的分子都在不停地做无规则的运动。只有分子不停地运动才能相互进入对方。同时也说明分子不是紧密地挤在一起，而是彼此间存有间隙。

（2）分子间的作用力

固体、液体的分子都在不停地做无规则运动，且分子间又有间隙，为什么分子不会飞散开，反而聚合在一起呢？引导学生猜想，这可能是分子间存在着吸引力，这个猜想是否正确呢？需要我们用实验来证实。

演示实验：分子引力实验

出示演示分子引力的两个铅圆柱。随意将它们对在一起，这时两铅块并没有表现出吸引力。实验似乎得到分子间没有引力的结果，但是我们不要轻易地放弃我们的猜想，应再进一步分析原因。大家都知道磁铁能够吸引铁钉，（边讲边演示）但把铁钉远离磁铁，这时磁铁不能吸起铁钉（演示），这是为什么？（距离太远）。刚才两铅块没有表现出吸引力，是不是也是因为分子间的距离不够近呢？那么我们想法让两铅块靠的更近些。（再做实验时，用小刀将两铅块表面刮光亮，然后用力将两铅块挤压在一起）

实验结果两铅块能吸引在一起，并能负重达500克以上。这表明分子之间的吸引力，这种吸引力只有在分子靠得很近时，才能表现出来。一般分子距离要小于10—9米时才能表现出引力。

在实际生产中，人们早就利用分子间有吸引力，来进行金属焊接了。一般焊接是靠溶化金属，从而使分子间的距离足够近，金属冷却后就焊接到一起。近代还有爆破焊接技术，它是将金属表面清洁后靠在一起，然后靠爆炸产生的巨大压力，将两金属压接在一起。

液体分子之间也存在吸引力。

实验证实了我们关于分子引力的猜想。我们再进一步思考，又会发现新的矛盾：分子之间有间隙，分子之间又有引力，这两者是矛盾的，分子想互吸引最终应该相互靠紧，而不应该有间隙。既然分子间有间隙，物体应该很容易压缩，但事实却是固体、液体极难压缩。我们只有根据事实，深化我们的认识，事实表明我们对分子的认识还不够全面，还有没认识到的方面。

原来分子之间还存在斥力。分子之间既有引力，又有斥力，会不会两种力总是相互抵消呢？当然不会，只有在特定的距离r时，分子间的引力不等于斥力，这个距离r就是通常的分子间隙的距离，大约是10—10米。当分子距离小于r时，斥力和引力都增大，但斥力增大得快，分子间表现为斥力。当分子间距离增大时，斥力和引力都减小，但斥力减小得更快、分子间表现为引力。当分子距离再增大，分子引力继续减小，当分子距离大于10r时，分子间的作用力将变得十分微弱，可以忽略了。

有了对分子间存在斥力的认识，前面所说的矛盾也就迎刃而解了。

小结：

通过实验和思考，我们已经对分子和分子的运动有了初步认识，现在我们共同回顾一下，看看我们已经有了哪些认识。

1、物质是由分子组成的，分子是构成物质的微粒，直径大约是10—10米。

2、分子永不停息地无规则运动着。

3、分子之间有间隙。

4、分子之间存在作用力，相互作用力有两种，即引力和斥力。

以上几点，就是分子动理论的基本要点，利用这些要点，能够解释很多热现象。

分子课件【篇10】

结构化学首先是一门直接应用多种近代实验手段测定分子静态、动态结构和静态、动态性能的实验科学。结构化学它要从各种已知的化学物质的分子构型和运动特征中归纳出物质结构的规律性，还要从理论上说明为什么原子会结合成为分子，为什么原子按一定的量的关系结合成为数目众多的形形色色的分子，以及在分子中原子相互结合的各种作用力方式和分子中原子相对位置的立体化学特征。结构化学还说明某种元素的原子或某种基团在不同的微观化学环境中的价态、电子组态、配位特点等结构特征。

另一方面，从结构化学的角度还能阐明物质的各种宏观化学性能（包括化学反应性能）和各种宏观非化学性能（包括各种物理性质和许多新技术应用中的技术性能等）与微观结构之间的关系及其规律性。在这个基础上就有可能不断地运用已知的规律性，设法合成出具有更新颖、结构特点更不寻常的新物质，在化学键理论和实验化学相结合的过程中创立新的结构化学理论。与此同时，还要不断地努力建立新的阐明物质微观结构的物理的和化学的实验方法。

与其他的化学分支一样，结构化学一般从宏观到微观、从静态到动态、从定性到定量按各种不同层次来认识客观的化学物质。演绎和归纳仍是结构化学研究的基本思维方法。早期的有关物质化学结构的知识可以说是来自对于物质的元素组成和化学性质的研究。当时人们对化学物质（包括各种单质和为数不多的几种化合物），只能从对物质组成的规律性认识，诸如定比定律、倍比定律等加以概括。随着化学反应当量的测定，人们提出了“化合价”的概念并用以说明物质组成的规律。那时，对于原子化合成分子的成因以及原子在分子中的排布方式可以说是一无所知。

结构化学的产生与有机物分子组成的`研究密切相关。有机化学发展的初期，人们总结出许多系列有机物分子中碳原子呈四面体化合价的规律。为解释有机物组成的多样性，人们提出了碳链结构及碳链的键饱和性理论。随后的有机物同分异构现象、有机官能团结构和旋光异构现象等研究，也为早期的结构化学研究提供有力的实验证据，促使化学家从立体构型的角度去理解物质的化学组成和化学性质，并从中总结出一些有关物质化学结构的规律性，为近代的结构化学的产生打下了基础。

近代实验物理方法的发展和应用，为结构化学提供了各种测定物质微观结构的实验方法；量子力学理论的建立和应用又为描述分子中电子和原子核运动状态提供了理论基础。有关原子结构特别是原子中电子壳层的结构以及内力、外力引起运动变化的理论，确立了原子间相互作用力的本质，也就从理论上阐明了化学键的本质，使人们对已提出的离子键、共价键和配位键加深了理解。有关杂化轨道的概念也为众多化合物的空间构型作出了合理的阐明甚至预测。原子中电子轨道空间取向的特征也为共轭体系（如苯环、丁二烯等）的结构以及它们的特殊化学性质作出了解释。

近代测定物质微观结构的实验物理方法的建立，对于结构化学的发展起了决定性的推动作用。X射线衍射结构化学方法和原理上相当类似的中子衍射、电子衍射等方法的发现与发展，大大地丰富了人们对物质分子(特别是在晶体中的分子)中原子空间排布的认识，并提供了数以十万种计的晶体和分子结构的可靠结构数据。基于对单质和简单的无机盐类（包括矿物）晶体的衍射测定，人们总结出并不断地精细化了有关原子和离子半径的数据。对于较为复杂的化合物晶体，也通过了衍射法测定了键长、键角等基本参数，还发现了原子之间键合方式的多样性和在不同聚集状态下分子间作用力方式的多样性，尤其是运用X射线晶体衍射方法测定了近三百种生物体中存在的蛋白质大分子结构，其中有些蛋白质的分子量达到十几万甚至几十万原子量单位。此外，通过晶体衍射的研究，使人们能够从分子和晶体结构的角度说明这些物质在晶态下的物理性质（如光学性质和电学性质）。

另一类测定结构的方法是谱学方法。谱学方法在提供关于分子能级和运动的信息，尤其是更精细的和动态的结构信息方面起着重要的作用。如分子振动光谱（红外和喇曼光谱）是鉴定物质分子的构成基团的迅速和有力的工具。因而被称为化学物质的“指纹”，与电子计算机高速信息处理功能结合起来，人们已能通过计算机的检索和识别很快地查明未知物样品的分子结构。红外喇曼光谱的理论处理，还能提供有关振动力常数等有关化学键特征的一些数据。其他谱学法有:核磁共振谱、顺磁共振谱、电子能谱（包括光电子能谱、X 射线光电子能谱、俄歇电子能谱）、质谱（见质谱法）、穆斯堡尔谱学、可见-紫外光谱、旋光谱、圆二色性谱(见圆二色性)以及扩展X射线吸收精细结构等。

物质的某些物理常数的测定，也能提供有关分子结构的某些整体信息，如磁化率、折射率和介电常数的测定等。此外，高放大率、高分辨率的电子显微镜还能提供有关物质表面的结构化学信息，甚至已能提供某些分子的结构形象。

2.重点、难点剖析

(1)电解质和非电解质均是指化合物而言，但认为除电解质之外的物质均是非电解质的说法是错误的，如单质不属于非电解质。

(2)电解质与电解质溶液区别：

电解质是纯净物，电解质溶液是混合物。

(3)电解质必须是在水分子的作用或受热熔化后，化合物本身直接电离出自由移动的离子的化合物，才是电解质，并不是溶于水能导电化合物都是电解质。如 等溶于水都能导电，但 是非电解质。它们导电的原因是：

这些自由移动的离子并非 直接电离出来的。

(4)电解质溶液导电能力是由溶液中自由移动的离子浓度决定的，离子浓度大，导电能力强;离子浓度小，导电能力弱。离子浓度大小受电解质的强弱和溶液浓度大小的决定。所以强电解质溶液导电能力不一定强，弱电解质溶液导电能力也不一定弱。
