Dear Mr John,
亲爱约翰先生，
How are things going with you in Beijing?
你在北京一切安好吗？
I am writing to show my thanks to you. You tutored me in my spoken english before you went to Beijing. With your help I made such rapid progress that i won the first place in the spoken english competition of the city. My achievement is owed to your help. Thank you very much.
我写这封信是为了表达我对你的感谢。在你去北京之前，你辅导我学习英语口语。由于你的帮助，我进步很快，在市英语口语比赛中我获得了第一名。我的成就都是源于你的帮助。非常感谢。
I have heard that you and your wife will pay a visit to my school. I am very glad at the news.In that case we can see each other again. I am looking forward to your coming. I am sending you a telescope as a small gift. I hope you will like it.
我听说你和你妻子将要来拜访我们学校。我很开心听到这个消息。如果那样的话我们又可以再见到彼此了。期待你们的到来。我给你寄了一个望远镜作为一份小小的礼物。希望你喜欢。
All the best.
Yours,liu jie
最好的祝愿，
刘杰
