Dear XXX,
I am very glad to tell you that I have been chosen as a volunteer for the 2008 Olympic Games. You cannot imagine how excited I am! As you know, this is a really precious chance to learn. Through the strict training that I am going to take, I am sure I will make great progress not only in English, but also useful skills in communication and organization. I can't not wait to meet new people and foreign friends from all over the world.
I hope you can join us soon.
Best wishes!
