二、Presentation

 1、教师请学生将装有蔬菜卡片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。

       2、教师将自己带来的蔬菜卡片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。
