Step 2 Reading （1）

We’ve learned a lot about computers，but can you imagine that computers could be put into androids or robots.Think of the fun you could have!Now let’s first read the passage about a robot called Andy—what it looks like and what it can do on Page 22，and then we’ll have a designing competition to see who will design the best robots.

The students read the passage for several minutes.

T：A few simple questions for you.What does Andy look like?

What can it do?

S2：Andy looks like a human.It is designed to play football games and can move and think like a human.Andy is really smart.

T：I agree with you.Are you eager to design your smart robots?Now in small groups discuss how to design your own androids，draw a picture of your androids and write down your design.You may refer to the following questions：

1.What would you like it to look like?

2.What are some of the things you would like it to do?

3.Do you want it to be like a man or a woman or neither?

4.How much would it cost?

T：And don’t forget to use the following expressions in your discussion.

I think that

In my opinion...

What is your reason?

I have decided that...

After several minutes.

T：Now，I’ll check your work.One from each group will show your picture of the android you have designed and tell the class your design.And we’ll see which group has designed the best android.Who would like to try first?

S3：Look here.This is the picture of the robot we’ve designed.What does it look like?Yes，it looks like a dog.We all like dogs very much.Every morning it will wake us up so that we will not be late for school.Then it will company us to school and carry our heavy bags.You know how heavy our bags are!In the evening，after a whole day’s hard work，it will play beautiful music to help us relax.Maybe it will cost at least 2000 yuan，but we don’t think it is too expensive to have such a good friend.

S4：Well，we’d like to design our robot in this way.We would like it to look like the famous footballer Beckham who serves as a striker on the football team.It has the most advanced program，so it can move and think like Beckham，and of course can shoot good goals like him.We would like it to enter the next Electronic World Cup，and we are sure that it will win the cup!

T：Your designs are very unusual and smart.I really want to go on appreciating your designs，but time is limited.Will you put up your pictures of the robots you have designed with instructions on the back wall，and then decide which group has designed the best androids after comparison?
