（1）教授单词"light"

T: I take a present to you. Close your eyes. （拿出一个红色的大气球）Look! What's this? What color is it? Can you talk something about it?

Ss: It's a balloon. It's red. It's...

T: Yes, it's big and light. 引出课题并板书，教授单词light.

让学生传递气球，亲身感受并说单词light.

[设计意图] 用漂亮的红气球吸引学生的注意，让学生伴随自身的感受学单词，激发学习兴趣。

（2）教授单词"broken"、" pocket"

T: Pass me the balloon, please. (教师故意把气球扎破)Oh，What's wrong? 引导学生说"it''s broken！" 顺势把破气球装在口袋里，问：Where is my broken balloon? 指着口袋教学单词"pocket"。

（3）教授单词"heavy"、"hard"及重点句型

T: (出示两个实物包)Look ,I have got two bags. （出示黑色的小包）Can you talk something about it with the sentences?板书重点句型：This black bag is.../It's...

Ss: (引导学生说)This black bag is small/light...It's...

T: Look, This black one is light. So it'll be easy for me.(板书重点句型)

This blue one is heavy. So it'll be hard for me.(板书hard) 分别传递两个包，操练以上两个句型。

[设计意图] 利用事物呈现新单词和重点句型，形象直观，TPR教学方法能给学生真实语境学习英语。
