Zhang Lin is one of the volunteers serving in Shanghai World Exposition. The reasons for him to do so are as follows.

First of all, it’s a good virtue to help others. He was once helped by others so he wants to do something useful in return. Secondly, by helping others he has gained valuable experience and has built up his confidence. What’s more, volunteering makes his life more colorful and more meaningful.

As far as I’m concerned, it’s the volunteers who make Shanghai World Exposition a great success. So I’d like to be one of them to help visitors and I hope I can improve myself through serving others.
