范文：
Dear Tom,
Thank you very much for your kind help when I stayed in America . With your help , my English has improved a lot and my teachers and friends are surprised at my fluent English.
How is Mr. Smith ? I want to know something about his life. I tried to get in touch with him ,but unfortunately I don’t have his address and can’t connect with him .Do you have his email address or his telephone number?
The spring festival is coming . It is an important traditional festival for Chinese , when all the family members get together . It is like Christmas in the western countries .Would you like to come to feel the Chinese culture ? I am sure you will live happily here and learn a lot of funny things . Besides, I can also show you around some places of interest.
Best wishes ! I am looking forward to your reply .
Yours ,
