Dear Sir/Madam,

I heartedly want to be a volunteer of yours. Here is something about you. I am a student who will graduate senior high school. I always regard my class as our family or sacrifice my personally interests whenever necessary. Besides take an active part in class activities, I work responsibly to build up a good reputation for the team, I respected all the people around me and I'm always willing to give a hand to those in need. I'm strict in myself, making every effort to achieve an all-round development. In time of difficult, I always keep strong minded.

In addition, I am good at English both in speaking and in writing. I was in an American host family for 20 days in the summer camp and know how to get along well with foreigners. Looking forward to your early reply.

Sincerely yours,

Li Hua
