Dear Mr.John,
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.
How are things going with you in Beijing I have heard that you and your wife will pay a visit to my school when you are back. I am very glad at the news. In that ease we can see each other again. I am looking forward to your coming.
I am sending you a telescope as a small girl. I hope you will like it.
All the best!
Yours，
Li Yuan
