养宠物的建议
Dear Lily:
I think you had better feed a hamster,the trediest kind of pet these days is the small hamster. People like them because they are quiet and clean. I have a hamster named Tom,it’s very cute and easy to take care of,and it’s cheaper than rabbits or cats,so I bought it.
She’s my best company,because she reads books and litens to music with me every night.However,life with a hamster isn’t always perfect,she sometimes noisy at night ,she love sleep all day,too. So,sometimes she is very boring! How do you think?

Panda
Panda is one of the scarcest animals. People in the world like it very much. there used to be many pandas in China long ago. As the balance of nature was destroyed and the weather was getting warmer and warmer, pandas became less.
But at present, the number of pandas is increasing year by year. there are now so many pandas that some are being sent to other countries so that people there can enjoy them.
Nowadays, the biggest nature park for panda in China is in Sichuan. there is a research centre for nature and wild life there. Scientists hope that one day they will have enough pandas to be set free and let them live in the wild again.
