推荐信样例 一（管理）
Dear Sir/Madam:
In the capacity of the former dean of "Dalian Management School" of Dalian University of Technology(DUT), I am writing with pleasure to recommend Mr. Cai to your esteemed university.
I got to know him personally when he was taking the course--Methodology of Management Research (or Methods of Management as stated in his transcripts), a course I taught, concerning basic research methods, especially quantitative approach to management research. Then he took one of my other courses--Advanced Strategic Management. Mr. Caleb showed great aptitude on both courses and he got 78 on both, which seem a bit lower, but if you take the difficulty of the test papers and my strict grading into account, you will understand why such scores are still among the top five. Undoubtedly, he got excellent scores on other courses and ranked among the top 5% of his class after the first year of graduate study.
To my knowledge, Mr. Cai is not only strong in academics, but also in sports and social activities. He was the captain of the soccer team of graduateschool of DUT and led the team to play in the soccer league of our university for two successive years. He was also one of the main founders of the first academic club--"Management Forum" of the "Dalian Management School" of DUT.
After I left DUT, he still keeps in touch with me from time to time and I am pleased to see that he proved his outstanding capability in both research and teaching position. Therefore I feel very delighted when he told me he would like to pursue his advanced studies in your honored program. I am confident that Mr. Caib will contribute greatly to your program as well as he did in the DUT. Please don't hesitate to contact me if you need more information.
Truly, yours

XXX
