Dear sir or madam: I am xxx, general manager of xxx. Learning that an excellent staff member of ours, Mr. xxx, is intent on further studying abroad, I am much pleased and gratified. In my opinion, such a promising youth striving for progress should receive better education so as to create a brighter future. Therefore, it gives me a high honor to strongly recommend this outstanding young man to your world-renowned university. Mr. xxx once did practice in our company during his last academic year at university. Though he was not familiar with business and lacked working experience, he never admitted defeat. Instead, he allowed no opportunity to study to slip away. Taking full advantage of leisure time, Mr. xxx read through volumes of books on business and modestly consulted with more experienced staff members. Gradually, he became well versed in various business matters and achieved certain results. Never satisfied with his accomplishments, Mr. xxx continued to communicate and discuss with colleagues about puzzles he encountered until finding solutions. In light of his praiseworthy performance during the internship, we made an exception to recruit him as a full member after his graduation (we seldom hire recent university graduates). By now, as a business elite of our company, Mr. xxx works even more seriously, responsibly, and diligently, setting a good example for other staff members. Every drop of sweat has been repaid. Mr. xxx has been appraised as an excellent employee and awarded a considerable bonus. Yours, XXXX

范文三

University of Science and Technology Hefei, Anhui 230026, P.R. China July 1, 1998 Dear sir or Mr. xxx: Mr. Ren was admitted in 1986 at the age of 14 into the special class for gifted youths, my university's unique program that caters to the intellectual needs of unusually talented Chinese youngsters. It was a rare privilege he earned with his nearly impeccable academic performance throughout his elementary and secondary school years. He impressed me almost as soon as he entered my university, a major cradle of China's scientific and technological talents. At that time, members of the gifted class all had to spend half a month studying the principles of calculus on their own and then take an exam so that we could evaluate their self-study capability. Mr. Ren scored the highest grade in that exam. He also exhibited a keenly whetted mind during class discussions. To my regret at the time, his English was not as good as his mathematics or physics. But I noticed he made a point of working especially hard to improve his English during his five undergraduate years with us. By now, he seems to be at least as proficient in English as most of his former classmates in the gifted class. Considering his application, I would greatly appreciate it if you decide to accept him as he wishes. Yours sincerely, X X X X
