这里有个为高中生写的推荐信，我觉得很全面、语言诚恳有感染力，你可以参考。
Sir or Madam:
It is a pleasure for me to provide an evaluation in support of the application of Mr. Cai Yubiao, whom I have known for six years and taught English for three years in middle school. Later I acted as counselor of his class and he became my friend. I have full understanding of him in many aspects and I can say responsibly that he is a rare excellent student our school has produced.
Mr. Cai impressed first of all with his distinguished scholastic performance and his all-round development. He is almost a hero-like character on the campus. He is widely recognized, for his rank of always being one of the top five in various tests and exams, for his well-balanced development in all fields, for his broad horizon which is rarely found in other students. As a result, he had been conferred with the title of "Student of Excellence" for three consecutive years, the highest honor in most Chinese high schools. His mastery of computer science, which is far above school requirement and even higher than some of the college students, is most talked about and admired by both the school faculty and students. What especially surprised me is that his tutor in the computer contest told me that he obtained such achievement solely through his painstaking self-education. It is already beyond his teachers to offer him any advanced knowledge.

It is undeniable that Mr. Cai is very talented. But he achieved succeeded not simply out of his talents but more out of his diligence. When he first entered the 7th grade, he was just an average student. Now, he is especially admired for his piles of achievements in various highest-level contests and competitions. The prizes such as 1st place winner in National Olympics for Informatics, 2nd place winner in National Olympics for Mathematics, 3rd place winner in Provincial Olympics for Chemistry are only a few of the items. The reason for such a drastic improvement is that he has mastered effective learning methods which enhanced his scholastic aptitudes. Comment in common about him is that he is a person with a tightly packed schedule that is scientifically and reasonably made. "Less time, better work" or "Play while play, work while work" is what many of his peers describe of him jealously. He is so impressive for his well-planned and efficient studies. A colleague of mine once told me that a boy living in the opposite building would read English aloud for two hours every evening and play half an hour badminton and then go to bed. She said she very much appreciate the persistence of such a student. This student is Mr. Cai and my colleague's description has convincingly explained why Mr. Cai excels his classmates in English.
Being enthusiastic about his work, earnest in learning, he is also full of passion and initiative. What has always been talked about among the school faculty is about the days when Chai Yibiao squeezed out time to search through the web for teaching materials and worked deep into the nights to integrate them into multimedia animations and other forms of teaching aids and this product is now well-kept as a token of the valuable friendship between teacher and student, also the achievement made by students now being repeatedly used in class. For the past 6 years, together with his classmates, Mr. Cai often paid visits to the community welfare center to extend greetings and best wishes to the old people. He is also ever ready to show his love and care to each classmate.
As a matter of fact, he has been tutoring one of them in a one-to-one manner for a non-stop three years, for as much as 5 hours a week, which has now been an anecdote in the school.
Rather than score-oriented, he does equally well in after-school activities. The tutor of his extracurricular astronomy project recalled when Mr. Cai first joined the project as a 4th grader in primary school, he looked very small. When asked "Will you feel afraid to make observations deep into night in the wilderness?" he answered with courage: "Not in the least." By now, he has made 8-year efforts to do astronomical observations, even during the final year of his senior middle school when the coursework is so heavy. In other related aspects, Mr. Cai led his class's volleyball team to win the championship in the all-school man's volleyball league match and he himself won several first prizes in the long- and medium-distance running events at the school's sports meet. He represented our school at the two major English speech tests, one provincial-level and the other municipal-level, in which he won the 4th prize and first prize respectively.
In a word, he is a remarkable person. Not only his intelligence, but his maturity and willingness to help other people are really unusual, especially among high school seniors. Of course, he is by no means perfect. As a student of less than 20 years old, he has great potential to be tapped.
Therefore, he needs to be put into a more challenging environment to enrich and improve himself. An outstanding student needs an excellent academic environment and I believe that your esteemed university will surely provide the best study conditions.
At the same time，I strongly believe he will make a great learner, scholar and hopefully, a great man. I sincerely wish that his application could be most seriously and favorably considered.
