dear professor：
mr ma requested a letter of reference from me to support his application for graduate studies at your university. as his tutor when he prepared his project design for graduation, i am pleased to comply with his request. i became acquainted with mr ma when i met him on my class，his excellent capacity for analytical thinking and ability to express his ideas orally and i remembered his name at once. but i was astonihed by his learning ability; he listened to my lesson with his thought, especially when i taught them some emphases and difficulties of the course.i was impressed by his unique views about these difficulties which reflected his thought and logic better than othis students. i am glad to recommend this excellent boy who already possessed good quality and strong ability. i thisefore lend his my enthusiastic support and would appreciate you favorable consideration of his application.
sincerely yours
