Step4: Learn text

T:Today ,we are going to learn Module 5 Unit 1 I was two then.（板书课题并读一读)Boys and girls, Amy went to Lingling’s house .She saw lots of photos. Amy was very interested in Lingling’s photos . What are they talking about? and what’s the changes . Let’s have a look. (Amy到Lingling家做客时，对Lingling家的几张老照片产生了兴趣。让我们一起来看看照片上有哪些人，他们与现在相比有些什么变化。)

1.First , Now listen to the tape.让我们认真听课文。

2.Now listen to the tape again and answer the questions:再次听录音，并回答问题。

(1).Who is that little girl?

(2).How old was she then ?

(3).Was Lingling’s hair short then?

T:Who can answer this questions ?

3.Now listen to the tape again and repeat.让我们认真听并跟读模仿课文。

【设计意图】这个步骤重点培养学生的听力水平，在学习课文之前，给学生以“任务”，让学生带着问题去听，通过听对话内容能回答简单的问题，培养学生积极的学习态度，良好的听力习惯。

Step5: Practice 2

多媒体出多组图片，学生通过观察完成句子（现在与过去对比的图片）。

Her hair was shor then.Her hair is long now.

He is short then.He is tall now.

They were small(thin) then. They were big(fat) now.

I was 4 then. I am 10 now.

We were young then. We are old now.

【设计意图】通过照片的对比及图片的操练，进一步让学生明确了过去到现在发生的变化，做到了学以致用又培养了学生善于观察的能力。考虑到学情，我设计了用was, is和were, are进行看图填空，这样降低了学生表达的难度，尽量让每一个孩子都体会到成功的喜悦。

Step5.Summmerise

1、学生代表总结本节课的知识点，教师加以补充。

2、就学生本节课的表现进行评价，鼓励进步。

T: Wonderful! A song for you! Listen to me carefully.
