Dear Sir:
It is my pleasure to recommend Mr. Fu-ping Wang for his application to graduate studies in your school.
Mr. Wang has been my research assistant of the National Science Council’s project "The United States and the United Nations’ Financial Crisis: The Role of U.S. Congress" since September 1997. His major responsibilities include information collecting, analyzing and translating. He is an enthusiastic and progressive young man with extremely high potentiality. Mr. Wang is not only quick at learning and good at solving difficult problems, but also with a logical mind that enables him to effectively analyze difficulties. All the work handed to him was completed satisfactorily. Actually, he is so reliable that I assign him with heavy responsibilities. With his help, I have been able to spend more time in writing the research paper. I really consider myself very fortunate to have such a capable assistant.
I am certain his diligence, coupled with a good competence and pleasant personality, will assure him of academic achievements in his future academic pursuits. I strongly recommend his admission without any reservation.
Sincerely yours,
Chung Wei-kuo
Research Fellow and Professor
The Institute of European and American Studies

xx学校的朋友
您好!我是xx的导师xxx，xx同学是我最欣赏的学生之一。她最吸引我的是她的学习天赋与上进心，她是我见过的最聪明的学生，学习成绩卓著，人文科学与自然科学同样精通。更为难得的是她从不妄自尊大、自以为是，依旧刻苦地对待每一项学习任务，力争成为整个团队中的最佳。体现了她对自己和爱她的人负责的态度。
中国有句俗话：“梅花香自苦寒来”，经过她持之以恒地付出，她的语言表达能力、活动的组织能力、与人的沟通能力、独立研究能力都非常突出，连续获得学校三好学生。特别是对英语，她具有天生的天赋与逐渐培养起的热情，据我所知，她的雅思成绩非常高，并获得许多中学生英语竞赛的奖项。能在英语国家学习，是她很久以前的梦想，为此她早已经作好了准备。我总是情不自禁的感慨：她说的英语与我说的汉语一样棒!
姜不光是我的学生，还是我的朋友。因为她的个性与理想深深的吸引了我。她总是无私地为团队奉献自己的聪明才智，主动为大家服务，任劳任怨，不计较个人得失，成为我们眼中的英雄。她又非常幽默乐观，用她微笑传递给大家一天的好心情。她又是一名体育健将，长跑、游泳、野外探险是她生活的一部分，从中她的意志得到了锻炼。我们交往非常愉快，她特别乐于与我一起分享她成长中的喜怒哀乐。还常常与我谈论电影艺术和旅游，美国的文化与风景深深地吸引了她，那里有她一个梦想。
真舍不得她离开祖国，但我尊重她的选择，相信她会学有所成，正如我相信我们的友谊天长地久一样。谢谢。
此致
敬礼!
