【教学过程】

Ⅰ. Pre-task preparations

1．出示不同物品的图片，让学生自由讨论，并用一句话作介绍。

The watch is a great invention. The watch is an invention.

2．学生两人一组，介绍各自认为对人类有很大帮助的发明。

S1: I think the plane is a great invention. People can go anywhere in it.

S2: I think the camera is a great invention. People can take photos with it.

Ⅱ. While-task procedures

1．让学生看Ask and answer栏目的内容，然后根据提示和学生讨论各种发明的功能。

T: Let's look at these inventions. How can these inventions change people's lives?

然后，让学生两人一组对话。学生可以根据自己的学力，用已学句型描述某个发明的功能。待学生充分操练后，全班一起交流。

S1: Is the camera a great invention?

S2: Yes, it is. People can take photos with it.

2．出示现代飞机的图片，引入Read a story的故事。播放课文故事的动画，让学生通过观看动画理解故事，然后，教师提问，检验学生对故事的理解程度。

T: What do the Wright brothers like to do?

S1: They like to invent things.

T: What do they want to do when they see birds flying?

S2: They want to fly too.

T: What do they invent?

S3: They invent a flying machine.

T: How do they invent it?

S4: First, they watch how the birds fly. Next, they draw a picture of their flying machine. Then they build it. Finally, they fly like birds.

教师可以根据学生的情况，多次播放动画，或者让学生在看动画之前先关注问题，带着问题去看动画。

3．学生阅读故事并完成课本的排序练习，然后全班一起核对答案。

4．播放故事录音，学生跟读对话，提醒学生注意语音语调。先全班一起朗读，然后，学生分角色朗读对话。

Ⅲ. Post-task activities

1．根据排序练习，让学生说说故事的梗概。如果学生在介绍中有困难，教师可以提问，启发学生根据问题答案连句成篇。

S1: The Wright brothers like to invent things. They see birds flying. They want to fly like those birds. They want to invent a flying machine. First, they watch how the birds fly. Next, they draw a picture of their flying machine. Then they build it. Finally, they can fly like birds.

让学生思考莱特兄弟发明飞机的经过，总结他们成功的原因，鼓励学生向他们学习，善于观察，敢于想象并动手实践。

2．学生三人一组，分角色表演对话。
