dear professor:
this letter of recommendation is for caleb, a young man i have had the pleasure of knowing for the last 20 months. as a professor emeritus, i have come in contact with thousands of college and graduate students. however, mr. caleb stands out as a very extraordinary one with his research and teaching capability, personality and what is more, his xxxacademic spiritxxx.
during his graduate study, he worked as my research assistant first, then as a teaching assistant of our department. usually it is hard for someone to be good at even either one. however, as his adviser, i was pleased to find thatboth works he did was far exceeding what is called good. for example, unlike most other graduate students who are eager to publish essays and thus fear to take pains to make exhaustive investigation for their research, mr. caleb made extensive survey for his in the project sponsored by science and tech commission of xxxchicagoxxx municipal searched every possible source of information within his reach and affords for related materials. as far as i know, he has been to beijing to the national library of china, science and tech information center, tsinghua university s library and most public libraries of xxxchicagoxxx. he searched both in library and on web, which is a totally new approach to us. neither was mr. caleb satisfied with second-hand information only. during the process, he also interviewed with supervisors of some scientific institutes of xxxchicagoxxx to obtain first-hand information.
his teaching is equally praiseworthy. i often heard his students said that s lectures were interesting and enlightening and they loved to listen to his lectures. in fact, he has his own teaching my knowledge,it is quite western. in other words, he pays more attention to arouse the desire of seeking knowledge among his students instead of maintaining a quiet and rigid lecture atmosphere as most other teachers you can imagine his lectures are full of discussions, laughter and eager eyes of learning.
his personality also impressed me so much. i would like to take only one case among numerous ones as summer, i happened to have some thesessent to a professor who lived in another university for his was so urgent that i could not wait even one more moment. then i got mr. caleb to do it. he nodded without even hesitation. it sounds like not a big deal. however, it was scorching outside at noon then and it took him almost 1 hour s bike ride back and forth!
besides his research, teaching capability and personality,i think i should bring up the overwhelmingly strong point of mr. caleb--his academic spirit. although i know that it is hard to define what is called xxxacademic spiritxxx, mr. caleb does prove it through his independence on his research, innovative perspective and commitment to academic activity. frankly, i think it is the xxxacademic spiritxxxthat distinguishes him from thousands of college and graduate students i have ever known. with the xxxacademic spiritxxx, mr. caleb is marching steadily towards his career goal--an ideal scholar with time goes more point. mr. caleb s english is excellent compared to most college or graduate students i have ever example, xxxchicagoxxx municipal govern-ment held xxxinternational friendship monthxxx and invited many foreigners (including guests from clevend, .) last summer. mr. caleb was chosen as one of 6 volunteer interpreters out of nearly 300 college and graduate studentswho applied the positions. therefore i am sure that he will adapt to the rigors of graduate school life in . without any great difficulty.
our kind consideration will be greatly would like to providemore information upon your request. you can reach me either by the home phone and mailing address or via internet,my email address is: xxxx@xuexila
thank you.
