Hello! My name is Tom. David is my new pen pal. He is a heavy boy. He likes playing sports very much. He likes swimming. Swimming is an interesting sport. It helps him keep fit and relax himself(放松自己). He often goes swimming on Saturdays. He also likes playing basketball. He often goes to the gym and plays basketball with his friends. I like playing basketball, too. He sometimes invites(邀请)me to play basketball with him together.
