Dear friend,
My name is Jack and I'm happy to be your new pen pal. Let me tell you something about my family. My father is a doctor. He works in a hospital. He likes playing chess. My mother is a teacher in our school. We go to school by car every day. I am a primary school student (小学生). I like playing football. I am good at it and I want to be a football player.
I love my family and we are happy together. Hope to see you soon.
Yours,
Jack
