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 h**e a look.

amy到lingling家做客时,对lingling家的几张老**产生了兴趣。让我们一起来看看**上有哪些人,他们与现在相比有些什么变化。),now listen to the tape.

让我们认真听课文。

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 ?

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**出多**片,学生通过观察完成句子(现在与过去对比的**)。

her hair was shor hair is long now.

he is short 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**的对比及**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。

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.
