复习：游戏：教师将几个动物单词卡片贴到黑板上，并在下面标上序号，请任意学生说出其中一个单词，其他学生说序号并模仿该动物的叫声或动作。

教师说谜语，引导学生用Are they…?来猜猜是什么蔬菜。

What are they?They are round, pink and white. What are they?They are brown. French fries are made of them.

教师和学生聊一聊每个人喜爱的蔬菜或动物。

I like .…Do you like …?(三) 新课呈现：教师请学生将装有蔬菜的盒子盖好放在桌子上，然后走到同学们中间，随意指着几个盒子问：Are these…?，并引导学生根据实际用Yes, they are. / No, they aren’t.回答。

如果学生回答的是No, they aren’t. 教师要继续问：What are these？并引导学生用They are …回答。

（教师在操作时应多问几名学生，以增加语言的输入量。

）教师适时板书句型框架。

教师将自己带来的蔬菜分别放在几个盒子里，请几个学生过来边摸边问：Are these …?或What are these？教师做出相应的回答。

学生两人一组运用黑板上的句型互相猜猜对方盒内的蔬菜。

教师打开自制课件，请学生看一遍顾客和服务员的问答。

然后提问：顾客为什么要用Are those cucumbers？问，而不用Are these cucumbers？问，两者有什么区别？教师根据学生的理解情况适当讲Are those …的功能。

教师指着另外一盒蔬菜用Are those ...?随意说一种蔬菜名，然后点击，启发学生根据看到的用Yes, they are. / No, they aren’t.回答。

教师进行板书。

教师分别指向其他三个盒子启发学生用Are those..?提问，然后点击印证，让全班一起回答。

教师再次分别指着课件中货架上的几个盒子问：What are those？点击后引导学生用They are …回答。

教师进行板书。
