教学过程:

Pre-task preparation

1、借助多媒体,播放listen and enjoy的动画,让学生跟着录音朗读儿歌。

2、通过儿歌引出本课时的话题:What do you want to invent?

T: There are some inventions in the song. What are they?

S1: A flying car.

S2: A special toy.

S3: A special hat.

T: If you have a chance to invent something. What will you invent?

While-task procedures

1、导入Culture corner, 帮助学生了解四大发明的英语名称。

T:We have talked a lot about inventions. Now let’s take a look at these photos. do you know the names of these inventions? Who invented them?

A long time ago, the ancient Chinese people invented these things. They are the compass, gunpowder, papermaking and printing.

鼓励学生说说他们对中国古代四大发明的认识,以及他们所知道的有相似功能的现代发明。

2、教师提问,启发学生思考自己的小发明,并提供以下我是小小发明家的设计图,学生根据设计图画一画并写一写自己的发明设想以及发明的作用。

T: Do you want to be an inventor?

Do you want to invent anything?

What do you want to invent?

Why do you want to invent it?

Please draw your invention and try to describe it in your own words.  学生完成个人的小发明创造后,先根据自己画的图片和所写文字简单介绍自己的发明。随后,两人一组开展调查,巩固复习句型。

S1: Hello, (S2s name) Can I ask you some questions?

S2: Yes, please.

S1: Do you want to invent anything?

S2: Yes.

S1: What are you going to invent?

S2: I am going to invent...

S1: Why?

S2: Because...

3、调查结束后,调查员可以整理调查信息,重新分组后向其他学生汇报,也可以向全班汇报。由于牵涉到第三人称转述,教师需提醒学生注意动词的用法。

 Post-task activities

让学生根据练习册中task第一部分的句型提示语同学问答,了解彼此心目中最伟大的发明,然后根据问答所得信息完成调查表。最后,作为回家作业,让学生完成Think and write,写一写自己心目中最伟大的发明。
