Also , there are manyproblems with them. For example, the batteries must be replacedafter having been used for 300 to 400 times. If they are not changed in time, they would cause pollution again.

Dear Admission Committee:
Miss Pan Bei requested a letter of recommendation from me to support her application for graduate program at your university. As her teacher, I am pleased to comply with her request.
I first got to know Miss Pan when she enrolled at university and I was the assistant director of her class at that time. Being a professor for several years, I noticed that due to the lack of self-learning ability, it is really challenging for students, even those performing excellent in senior school, to keep up with the college speed. However, as a diligent girl without any solid background in Computer Science before college, she adapted quickly to the especially competitive environment in our department. At the end of the first year, she earned the 5th rank in her class, while ranking 1st among the girls. I was fairly impressed by her self-learning technique and exceptional efforts. Hence, I believe, goal-oriented, not afraid of inchoateness and with persistence, she has the quality to make achievements.
What distinguished her among her classmates, I think, was that she went far beyond acquiring excellent scores in the exams and instead got her range of knowledge enlarged. In spring, 2006, Miss Pan took the course I taught named Algebraic Structures and Combinatorial Mathematics. This inquisitive and assiduous young woman was sometimes the last to leave after my class, raising novel questions related to the subject. I found that she understood the knowledge in depth and detail. Furthermore, I still remember during the spring vocation in May, due to the break-down of my mail box, I missed her mails to discussing some questions. But the following week during the course time, she asked me directly. Her zeal for knowledge and the spirit to explore answers really leave me a deep impression. Finally, she was among the few students who got almost full marks in every test in class which showed her exceeding grasp of every chapter. Thus, I gave her 98/100 for the excellent performance in my course.
In summary, I have every reason to believe that Miss. Pan will make outstanding performance at your university as a graduate. I would appreciate greatly if you give her a favorable consideration. Please feel free to contact me directly if more assistance is needed. Faithfully yours,
Wanling Qu, Professor
Department of Computer Science and technology Peking University
