生词：国际贸易博览会 the International Trade Exposition
Dear Sir or Madam：
Thank you for taking your time to read my letter. As the coming of the International Trade Exposition, I’d like very much to be a volunteer。
All our citizens are hosts for this special event. Above all, I promise I should endeavor to serve with enthusiasm our distinguished guests from all over the world. Besides, I have a rich knowledge about Chinese history, so I will be not only a servant but also a carrier for our splendid culture. What’s more, as we all know, English as an international language, will play an important role in communication during the Exposition, and I am good at it. I can express myself fluently and clearly in English。
To sum up, I believe I can be a qualified volunteer. I will value it and do all I can if I could be accepted to be one。
I am willing to join you and become a member of your team to serve the Children's Hospital in summer vacation. It will be a meaningful voluntary activity.
There are several reasons make me qualified for your association. I am a warmhearted person with great passion. Also I have many experience working as a volunteer before. Most of all, I attach great importance to the sense of responsibility and team spirit.
I would appreciate it and be honored if you offer me that chance.
