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 progrethat 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.
Liu Jie
