　　Dear Li Lei,

　　I haven't heard from you for a long time. I'm glad to tell you that I'll visit Beijing this summer vacation. It is said that Beijing is a great city with a long history and more changes have taken place since the 2008 Olympic Games. I would like to know something about Beijing, such as places of interest, the environment, traffic and people there.

　　I'm looking forward to hearing from you soon.

　　Yours,

　　Tommy
