My robot’s name is Yanyan. It is a

321 model android. It works for me and

looks after my library. Its job is to store

all the books that I borrow from the

library or from school. Of course

Yanyan’s brain is as large as mountain

so work like that is no trouble at all.

Sample writing

Yanyan really eats and remembers books

just like people eat food.

I need Yanyan to remember all these

books, so it can help me do my homework.

I want to go to a key university but finding

the information I need is hard work. So

Yanyan can help me.

This leaves me more free time to play

sports and talk to my friends. It is the

most important thing for me and my

family.

My father says my robot may not be

cheap but it really helps me with my

homework.

the reader will want to carry on and

read all of it ．3. The article itself is in the smallest

writing, but contains all the

information about the story ．

information they have gained from

their interview with Hua Fei to

write the article. It should be in the

third person.
