Dear Sir/Madam,
　　I'm Zhang Fan from Grade Six. I hear our school will organize a summer camp called "Going into American Family". I want very much to take part in it.
　　I like all kinds of sports, and I like playing billiards best. I often watch billiards games on TV. I have learned a lot from it. If I get chance to America, I hope to live in a family with many children, and they have the same hobbies as me.
　　I'm waiting for your response.
Yours,
Zhang Fan
