推荐信是向收信人推荐某人做某事的信件，一般分为三个部分：
1.指出被推荐的人及推荐的原因;
2.介绍被推荐人的情况;
3.总结说明被推荐人值得被推荐(例如能胜任工作)。
Suppose you work as a part?time translator in a company. Now you are going to graduate and your friend Liang Bo wants to get that job. So you write a letter of recommendation to your boss Mr. Wang in about 100 words. Do not sign your own name at the end of the letter, using “Li Ming” instead.
Dear Mr. Wang,
I’m terribly sorry to tell you that I am going to graduate this June and cannot go on to work for you as a translator. It has been such a pleasant and precious experience to work in your company.
In addition to extending my gratitude, here I take great pleasure in recommending to you my friend Liang Bo, a sophomore majoring in English. He particularly desires to get this job when he knows about your company.
Liang Bo is a straight A student, good at both Chinese and English. Moreover, being cheerful, considerate and easy-going, he usually gets along well with others.
I am convinced that he is very suitable for the job. At last, I’d like to express my gratitude to you again and wish you a successful career.
Sincerely yours,
Li Ming
