My favourite animal is the panda. I love pandas because they are nice and lovely. You can see them in many zoos in the world. They all come from China. They spend a lot of time eating and sleeping in a day. Pandas are white and black， and their eyes， ears and legs are black. They look very cute. Many people like them. Do you love pandas？

Dear Susan，
I have lots of rules at home. I have to get up at seven o’clock every morning. After school， I have to get home before six o’clock. I have much homework to do after school. I must finish my homework on time. Then I need to exercise for about an hour. I can’t watch TV or play computer games on school nights. On weekends， I have to clean my room， before that I can’t go out. My home rules are important to me.
Yours，
Jenny
