　　Dear Brian，

　　How time flies! We have been friends for three years.I'm writing to thank you for your help !

　　Three years ago， when I came to a new class， everything was strange to me. I had no friends and felt lonely. It was you who helped me a lot.During the three years， you wrote to me many times and always encouraged me to make friends as many as possible. When I had difficulties with my English， you told me many good ways to improve it. Besides， you were always sharing happiness with me， which made my life more colorful.Thanks to your help， I have become more confident and positive. I really appreciate your help.

　　These years， great changes have taken place in Tianjin and I hope you can come to Tianjin to experience the new changes.

　　Hope to see you soon!

　　Yours，

　　Zhang Ming
