Dear Tom,
I have been a volunteer in 2010 Shanghai EXPO, it was really an unforgettable experience. Although volunteer's work was hard and tired, I still feel very happy.Because it offers me a good opportunity to help visitors from foreign counties thus can practice my oral English. I also enhance my sense of reasonability during volunteer work. I worked with other volunteers as a team, together we solved different problems, we also became good friends after EXPO. I was proud of myself and surely I will treasure this experience.
Yours LiKe
