Dear Sir or Madam,
I"m Li Hua, a middle school student from China. I read the announcement of the summer camp that you have posted on the Internet and I am interested in it.
I know that you welcome students from different countries and I"d like to take part in it. I"ve been learning English for 10 years, and I speak fluent English. What is more, I"ll be able to tell students from other countries about China and learn about their countries as well. I hope I will be accepted as a member of your summer camp.
Looking forward to your reply!
Yours
Li Hua
