Dear Sir:
I am a student from xxx school. I am willing to be a volunteer for World Gardening Exhibition .
2011 World Gardening Exhibition in Xi'an is not only a significant event to Xi'an, but also a momentous occasion in the world. I have been dreamed to contribute myself to our society for years, I am so proud that I know I must take part in it.
I am a diligent and well-behave student in my school, thus I received model pupil award this year. I am also warm-hearted and easy-going, so I am very popular along my schoolmates. Last year I took part in xx English competition held by government and won the first prize. it shows that there will be no difficulty for me to communicate with foreign tourists and athletes. Therefore I believe I am able to do well if I become a volunteer.
You can call my number, which is xxxxxxx if you have any doubt. I hope you can consider my sincere request.
Faithfully xxxx(name)
