Dear sir or madam：
i am a student in this university who regularly come to the library to spend my spare time. generally speaking, the services you offer here is quite good; however i have some suggestions for you to adopt. and i would like to extend my greatest appreciation if you are so kind as to take my suggestions into consideration.
to begin with, would you please prolong the time for reading? in the day time, most of the students are having class, so they cannot come to the library. what is more, some of the books on shelves are out of date. if you are so kind as to provide us some books such as the latest magazines, we will be greatly honored.
i really wish to have a more comfortable library. thank you for your time and your consideration.
yours sincerely,
li ming
