【正确答案】 Dear Sir/Madam,
As a student of this university and a regular visitor to library, I feel that it is my obligation to make a suggestion concerning the use of air conditioner in Reading Room A on the third floor of the library.
In the first place, I would like to take the opportunity to express my gratitude for the comfortable environment you have provided for us. However, many students as well as I feel that it is too cold to study in Reading Room A. As I find out, the air conditioner in Reading Room A is set at 22℃ from day to night. It would be more comfortable if you can set the air conditioner at 26℃, which is also more environmental-friendly.
I would really appreciate it if my suggestion could be considered and positive changes take place in this regard.
Yours sincerely,
Li Ming
