Dear headmaster,
Hello.This is Zhanghong,a student of Class xxx,Grade xxx.I am glad to hear that there will be a summer camp called Going in American Families in our school.I think it is a good chance for me to improve my English and know more about America,so I would like to join it.I am good at speaking English and can get on well with others.I hope I will stay at an American family who has a single child,for I am a the only child in my family too.
Regards
Yours
Zhanghong
