【答案解析】[参考范文]
Dear President,
I am a senior of our university, majoring in Computer Science, and I am writing this letter to you to express my sincere wish to become a volunteer to go to Guizhou province.
The foremost reasons for my desire are as follows. To begin with, I am from a village of Guizhou province, so I know the situations of poor areas there much better. What"s more, because my major is computer science, I can help children there learn more about scientific knowledge, which will greatly contribute to the local development.
I will teach the children with the greatest passion and cherish the chance you give me. I am looking forward to your reply.
Sincerely yours,
Li Ming
