My hobby is reading. I like reading novels, newspapers, magazines and so on. When I was 9 year old. I caught bad cold. I have to stay at home for several weeks. My mother bought to me some novels. Soon I was attracting by the stories. Since then I have made use of any time to read. And reading does give me many help. Recently, I have surfed the Internet at home, on that I’ve found that many students like read as I do. We exchange our reading experience online but we become good friends. Reading brings me all happiness and friendship.
