I'm Zheng Hui. I'm a pupil. My school is very beautiful. There is a big playground in it. We often play sports on it. There is a new library. We often read books in it. We also have a nice computer room. It's on the third floor. But three years ago, there was a small playground in my school. And the library was small and old. We didn't have a computer room, so I couldn't use computers.
