    My name is Tom Brown. I am an English boy. (1) I am twelve. I am a middle school student. From Monday to Friday I am very busy. We have six classes a day. At school, I like doing sports, (2) like playing basketball, tennis and soccer. So my favorite subject is P.E.. Mr. White is my P.E. teacher. He is very cool.
