【范文】
Dear Admissions Committee,
I am writing to express my full support for Xiao Xiao, who is applying to graduate school at [name of school]. Though I am currently a visiting scholar at the University of California, San Diego, I was Xiao's supervisor at the VVV University School of Architecture and Civil Engineering. In my [number] years in academia, Xiao stands out as one of the best students I've encountered.
As the professor in charge of VVV's student union, I spent several years supervising and working closely with Pan, who served as the union's chairperson and monitor. Pan's work included managing the routine affairs of his class of 76 students and planning many student activities. Consequently, through our close contact, I gained a thorough understanding of and respect for Pan's character, his strong organizational skills, and his leadership ability. For example, in fall 1997, Xiao organized an evening party for incoming freshmen. I still vividly remember the party's resounding success, as well as Pan's unswerving attention to details.
Dedication and passion are hallmarks of Pan's character. Although the work he did as a student leader was time-consuming and tiring, he never complained. He simply embraced his responsibilities, and enjoyed the tasks at hand. Students acknowledged his devotion to his classmates repeatedly: For four years in a row, the student body elected him monitor and chairperson. Xiao felt great warmth not only for his classmates, but also for society at large.
Sincerely,
Professor NAME
Department of Electrical Engineering,
