Dear Sir or Madam,

Thank you of your time to read my letter. As the coming of the 50th anniversary of our school, I'd like to

be a volunteer.

I'll try my best to serve for our distinguished guests with enthusiasm. I have good understanding of our

school. I am sure I'll not only offer good services to the guests, but I'll also act an excellent communicator of

our school's culture. What's more, I can say standard Chinese and English. I had no trouble working 8 hour a

day this coming weekend.

I will value the chance and do all I can if I am accept.

Li Hua
