写信给世博组委会要做世博志愿者英语作文
Dear sir，
Since Shanghai will hold the 2010 World Expo, I want to be a volunteer. So I can not only make many friends, but also practice my English. If I am a volunteer, I can intruduce the history and the resorts to the foreigners. Of course, to be a qualified volunteer, there are still many things I need to learn. Please give me a chance and I will do my best.
Sincerely Yours
Mike
