教学过程：

(一)Warm- up 1.Greetings and revision some words. 2.板出“am”

“is”

“

are”，让学生认读后，和学生齐说出，I用am，you用are，is跟着he, she, it；所有复数人称都用are。

3.Revision some words T: Before our class，let's play a game (和老师唱反调)。I say “big”

and you say “little”. OK? Ss : OK. T: big Ss: small Big—little

fat—thin

clean —dirty

tall—short

young—old

long—short

(通过游戏的方式对所学过的形容词进行复习，既增加了学生的学习兴趣又为下面的学习做了铺垫。) 4.自编的chant Tall,tall, I am tall.

Short,short,You are short. Young,young,He is young.

Old,old,She is old. Short,short,It is short.

Long,long,They are long. (全班拍拍手一起chant) (二)Presetation 1.(出示一张小孩子照片，让学生猜一猜) T: who is that little girl? Can you guess?

Ss: It's …. Ss: It's you. T: Yes. You are right. It’s me. (让学生理解me的意思并教授) I was short then. Now I am tall. And my hair was short then. Now my air is long. 2.出示蝴蝶的图片，告诉学生蝴蝶的蜕变过程，呼吁学生要爱护小动物，保护环境。同时更要爱护家人。

3.（继续出示一对老夫妻的相片, 让学生猜一猜）T: Who are they? Ss: They are ...，T: They are my grandparents. Now they are old.接着出示一张他们以前的照片，引导学生说出They weren’t old then. They were young. 3.继续出示一些图片，对比前后变化，强化be动词的用法。

4.带领学生归纳出本部分的知识要点wasn’t,weren’t. (三) Learn the text. 1、Listen and say. 播放课文的录音前，向学生提出问题，让学生有针对性的听音。听完第一遍录音后，引导学生在文中找到答案。

（设计意图：问题的设计让听音变得有效，帮助学生提高对短文的理解力。）

2、播放第二遍录音，让学生画出be动词am,is,are以及它的过去式was, were,wasn’t,weren’t.以及划出then和now。对比观察它们的用法。

3、播放第二遍录音，让学生逐句跟读。

（设计意图：用纯正的语音语调影响学生的发音。）

(全班读，分组读，个别读) （设计意图：给学生开口讲英语的机会，使其感受成功的快乐。）

（四）Practice 1.Read and circle. 出示一些图片，对比他们的变化。引导学生圈出单词。
