写英语作文 I want to be a volunteer拜托了各位 谢谢

To be a volunteer of 2008 Olympic Game must be interesting and exciting.I'm a common middile school student and I really want to be a volunteer.First of all,I should improve my own English,because there will be lots of foreigners in Beijing from all over the world ,I think it important and also necessary for a volunteer to understand when people talk to.And I should also set an example to protect the environment,I can do many things,such as pick up the litter that drops on the ground ,plant trees and so on.If I do so,our city will be clean and beautiful.
