Hello! My name is Mary. I am an girl. I am short with a round face, a small mouth and big black eyes. I am not too fat too thin. I am in in Wuhan Middle School. I am easygoing and like making friends other girls, but they must be good ones in many ways, such as study, obeying(遵守) school rules and so on. I like English very much. Now I can speak with my English teacher in class. I study very hard and do well exams. I want to be a teacher when I grow up. In my free time, I often watch TV or my favorite music and sometimes play games or chat with my friends on the line. I also help my parents a little housework. My parents both say I am a child. They like very much. This is me.
