此题为判断题(对，错)。

Suppose you are a student of Beijing University. You went to Guangzhou last month and un- fortunately lost your bag there with your student card, identification card and 3, 000 yuan in it. When you got back to Beijing, you received a parcel in which the two cards and the handbag are contained, and a bill of 3, 000 yuan. From the address of the writer, you know he is Liu Ming, a sophomore of the Mechanics Department of X University. Now you want to write a letter of commendation to Liu Ming.

You should write approximately 100 words. Do not sign your own name at the end of your letter. Use "Wang Fang" instead. You do not need to write the address.
