Dear Mr。 John，
How are things going with you in Beijing？
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。
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。
All the best。
Yours，
Liu Jie
