Step3 Speaking

Tell the students that we already have many different kinds of androids in our daily life. Show  some pictures of androids for different purposes---maid, adventure and work.

Then say to the students: Let’s design an android of our own! The following questions and expression_r_rs can help you:

*What would you like it to look like?

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

*Do you want it to be like a man or a woman, or neither?

*How much would it cost?......

Get the students to use the following sentences for discussion:

I think that…         What’s your reason?

In my opinion…    I have decided that…

Sample:

A: What would you like your android to look like?

B : In my opinion it should look like a bird.

A: That sounds interesting. What will it do for you?

B: I think it can sing beautiful songs for me day and night.

A : Oh, yes! That sounds good. How much is it?

B: It doesn’t cost much money because I will make it by myself.

A: Really?! Do you want it to be a man or woman, or neither?

B : I want it to be a beautiful girl named Kelly.

A: Please show it to us some day.

B: Oh, No money no talk.

Step4 Pre-writing

Say: Imagine what problems and delights this android might have to deal with while it is serving you. Try yourself in someone else’s shoes is an important way of understanding how other people feel.

Then discuss: You are an android. You work for a family with one child who is very spoiled. The parents want you to do everything for them. The parents are nice, but they often ask you to watch over their child. How do you feel? What would you do if the child asked you to do his/her homework for him/her? Would you ever tell the child “no”?

Step5 Writing

Say: Write a passage about the result of your discussion! It should contain:

What do you have to do?

What is the child like?

What is the parents’ requirement of the child?

What do the parents want you to do?

What does the child want you to do?

Then what will you do? How do you feel?

Sample writing:

Hello everybody, my name is Liu Yan.I am a 321 model android.I work for the Li family. Mr and Mrs Li work very hard too.Mr Li is an architect and designs great tall apartment blocks.Mrs Li is a doctor and has to look after many patients.I remember all the plans for Mr Li's projects and can tell Mrs Li which drugs are the best to give any particular patient. And I also look after their library. I store all the books that they borrow from their school or friends in my brain.Of course my brain is as large as a mountain, so work like that is no trouble to me.I really eat books just like people eat food.

The Lis have a child who is very spoiled. He needs me to remember all his school textbooks so that I can do his homework for him.He just gives me the information on the subject, what has to be done and the page numbers and I get on with it while he enjoys himself with his friends.Sometimes I don't think it is right to do his homework for him — it's somewhat cheating. However, his parents are very concerned at the pressure of work in school these days.The child has too much homework to do. They like him to go to the key school but they also want him to be able to have hobbies, learn to swim and keep fit! Poor child!

So they consider me the most important person in the family after themselves.I am always introduced to their friends and play with visiting children.I am the perfect family academic aid and, although I was not cheap to buy, Mr Li says I was worth every yuan!
