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”?
Step7 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?

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!

“good-looking” 特指外表容貌的美，多用于指男性。
辨析used to, be used to doing 与be used to do

此外，grow还可以作连系动词，作“逐渐变得”，后面跟表语。
She is growing healthy.她的身体逐渐变好了。
4．However, I find it hard. 然而我发现交朋友很难。
句中的it 指上句的making new friends（交新朋友）。全句相当于I find it hard to make new friends.由于it作形式宾语的用法还没有出现过，此处暂不宜向学生解释。
Find作“发现，觉得”，后面可以跟带形容词的复合宾语（宾语+宾补）
I found him very funny.我现他很滑稽可笑。
你觉得这个问题难吗？
5．This is secret, so please don’t tell anybody else.这是一个秘密，因此，请别告诉其它任何人。
