Dear Sir or Madam, 
Thank you for taking your time to read my letter. I am writing to apply to be a volunteer of the coming International Trade Exposition.
All our citizens are host for this great event. All of us should work hard to make well preparations for it. I promise I would try to serve for our honored guests from all over the world with enthusiasm. Besides, have a rich knowledge of Chinese history, I will be not only a servant but also a carrier for our splendidly culture. What’s more, English, an international language, will play important role in communication during the Exposition. Unluckily, I am good at them and can express myself fluently and clearly in English.
To sum up, I believe I can be a qualified volunteer. I will value the chance and do that I can if I could be accepted to be one.
Yours,
Susan
