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爱好。让我们一起来看看照片上有哪些人，他们及现在相比有些什么变化。)
1.First , Now listen to the tape.让我们仔细听课文。
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.让我们仔细听并跟读仿照课文。
【设计意图】这个步骤重点培育学生的听力水平，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，培育学生主动的学习看法，良好的听力习惯。
Step5: Practice 2
多媒体出多组图片，学生通过视察完成句子（现在及过去对比的图片）。
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育了学生擅长视察的实力。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胜利的喜悦。
