    O. Henry was a pen name used by an American writer of short stories. His real name was William Sydney Porter. He was born in North Carolina in 1862. As a young boy he lived an exciting life. He did not go to school for very long, but he managed to teach himself everything he needed to know. When he was about 20 years old, O. Henry went to Texas, where he tried different jobs. He first worked on a newspaper, and then had a job in a bank. When some money went missing from the bank, O. Henry was believed to have stolen（偷）it. Because of that, he was sent to prison（监狱）. During the three years in prison, he learned to write short stories. After he got out of prison, he went to New York and continued writing. He wrote mostly about New York and the life of the poor there. People liked his stories, because simple as the tales（故事）were, they would finish with a sudden change at the end, to the reader's surprise.

    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 interesting and important (重要的). I like Chinese, I always read Chinese books before 1 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(故事).

    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. This subject is really difficult for me.

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