题目内容：

    I'm Sara. I'm a middle school student. At school, we have nine subjects — math, English, Chinese, science, geography, history, art, P.E. and music. My mother is a Chinese teacher and she says Chinese is beautiful and important (重要的). I like Chinese. I always read Chinese books before I go to bed. I also like history. It is my favorite subject. Mr. Brown is great fun. In his history class, I can learn many interesting stories.

Mr. Green is my math teacher. He says math is useful and interesting, but I think it is boring. My science teacher, Mrs. Smith, is nice. I listen to (听) her carefully (认真的) in class. But I can't do well in the science exam(考试). I don't know why. Although it’s difficult for me, I will try my best to solve it step by step.

We always have art, P.E. or music in the afternoon. For me, the classes in the afternoon are fun and relaxing. In P.E. class, I like to play ping-pong with my P.E. teacher Mrs. Miller. She plays very well.
