Step 1 Warming-up 1. 分角色朗读Let’s talk的对话。

2. 谈论学校的今昔对比。对话示例如下：

T: Tell us about your old school, please. S: There were no computers in my old school. T: How do you know that?

S: Our head teacher told us. Step 2 Presentation 1. 学习Let’s try

(1) 教师在课件上出示迈克和陈杰看老照片的图片，先让学生猜猜他们在干什么，引出对话背景：Mike and Chen Jie are looking at the old photos and talking about them. 请学生读出题目并尝试猜测答案，进行听前预测。

(2) 教师播放第一遍录音，学生根据听力内容选择答案。

(3) 教师播放第二遍录音，核对答案。

2. 学习重点单词和句型

(1) 教学different 出示自己小时候的照片，T: Who is she? Guess… It is me. At that time, I had short hair and I was fat. Now I am different. All of you are different now.板书different，请学生说出它的意思，并教读。

(2) 教学active 板书句子：Before, I was quiet. Now, I’m very active in class. 请学生说意思，然后齐读。

(3) 教师接着谈论自己的变化并板书句子：I was short, so I couldn’t ride my bike well. Now, I go cycling every day.请学生说句子的意思，然后齐读句子，最后请学生模仿该句子说自己的变化。如：

I was short, so I couldn’t play basketball well. Now, I play it every day. 3. 学习Let’s talk

(1) 小组合作预习对话。学生先自学，画出不理解的单词和句子，然后小组合作讨论，相互答疑解难。

(2) 教师播放动画，提问学生：How did Mike change? 要求学生在对话中把问题的答案画上波浪线。核对答案。

(3) 教师播放课文录音，学生跟读全文。

(4) 教师再次播放课文录音，学生逐句仿读。

(5) 学生小组读对话。

(6) 学生分角色朗读对话。
