　　Dear Sir，

　　I'm very glad that the Fourth China Eurasia Expo will be held in Urumqi in September. As a citizen in Urumqi，I think it is our duty to do something for this great event. So I would like to be a volunteer to help to clean up the city parks and streets. And I think I can help to plant more trees and flowers，too. The more trees we plant，the greener our city will be. We can show the world a more beautiful city. The reason why I'd also like to be a guide is that I like English and I'm good at speaking English I want to show the foreigners around the Expo and our city. I'm sure I can be a good guide.

　　Hope to hear from you soon!

　　Yours，

　　Li Ming
