分析

What故事内容

本语篇围绕刘涛、杨玲等学生在科技馆观察并讨论变色龙的变色过程展开。故事展现了变色龙的三次变色过程,以图文并茂的方式呈现变色龙变色的原因以及学生们的反应,展示了世界的多彩和奇妙。

Why主题意义

本语篇通过语篇标题"A little friend"引发学生的好奇心,借助线索人物﹣﹣饲养员向同学们介绍自己的动物朋友变色龙,自然引出"变色"话题,场景贴近学生生活,便于学生理解。文末的读后问题"What changes colour?"引导学生在第一课时学习的基础上对色彩产生更深的感受,鼓励学生发现和探究世界上更多会变色的事物,从而进一步了解周围事物和环境。

How文本结构和语言修辞

本语篇是比较典型的日常交际对话,在Cartoon time的基础上,呈现了更多的颜色词汇,如brownyellow and red;涉及谈论颜色的句型"What colour is it?""It's ";表达感受的语言"It's cool!" "How come?" "Wow!"。文本结构清晰,内容易于理解,贴近学生生活实际,能调动学生的学习热情,且有现实意义和教育意义。

What animal friend is it?  

It’s the chameleon.

2、Let’s know and read

Do you want to know about the chameleon?

Here are three steps for you. 

First, let’s know what colour is it, OK?

3、Let’s ask

Now look, what colour is the chameleon  

Is it green all the time?

4、Let’s watch

Let’s watch and finish Task 1 on your learning sheet. 

5、Let’s find and check

Let’s check. What colour does the chameleon have? Look at my fingers, OK?

Are you right?

6、Let’s find

Who can?

7、Let’s repeat

Now let’s repeat what questions does the narrator (解说员) ask

Nice.

Do you know what does it mean? How about now?

What do they mean?

It means the chameleon. Now means the colour is different. It changers its colour.

So we know what colour is it.

Next let’s find how and why does it change colour.

8、Let’s look and say

At first, how many times does the chameleon change colour?

How do you know?

Now look, at first, it’s green. Next, it changes the first time. Then it changes the second time. At last, it changes the third time. So it changes three time. Let’s read: at first, next, then, at last

9、Let’s read, write and say

How does the chameleon change? Now, let’s read Picture 2 to 4, finish your learning sheet. 

At first, P2, what colour is it now?  Why does the chameleon change its colour?

You can tell me in chinese.

It means dangerous.

The chameleon wants to protect itself. So it changes into brown.

10、Let’s imagine

If you are the chameleon, what can you say?如果你是变色龙,你会说什么? 

(Then, P3, what colour is it now?   Why does the chameleon change its colour?  

The chameleon is angry.

It wants to protect its place. So it changes into yellow and red.

If you are the chameleon, what can you say now? 

At last, P4, what colour is it now?  Why does the chameleon change its colour?  

He is safe. So it changes into green again.

If you are the chameleon, what can you say now?)
