Suppose your sister is going to take one-month training in another city. Write a letter in about 100 words to introduce her to a friend there. Do not sign your own name at the end of your letter, using “Li Ming” instead.
Dear Sherry,
I want to introduce to you the bearer of this letter, my younger sister, Linda. She is going to take one-month training in Nanjing University. She is a lively and lovely girl, whom I am sure you will like to make friends with.
But since it is the first time she goes to a strange city, I am a little worried. I would be ever so obliged if you would be so kind as to meet her at the railway station and accompany her to Nanjing University to register for the course. She will have no problem with her accommodation. I hope it will not cause any inconvenience for you. By the way, my sister’s mobile phone number is 13762788030.
Thanks very much.
Sincerely yours,
Li Ming

语言注意点介绍信应措辞礼貌得体，对被介绍人的说明应简洁明了、重点突出。
Write a letter to inform a colleague of a coming visiting scholar in about 100 words. Do not sign your own name at the end of your letter, using “Li Ming” instead.
Dear Anna,
Please allow me to take this opportunity to introduce a visiting scholar, George Martin, from University of California at Berkeley. He will be a member of our Program of Asia-Pacific Economy for nine months.
George is an enthusiastic and enterprising scholar. He has done various researches on American and Asian economies for more than ten years. I am sure that his participation will do a lot of help to our recent research.
George will be arriving here on next Friday and he will soon go to visit you after arrival. You can introduce the overall development of our program to him, and then explore the details of cooperation.
