Dear Sir or Madam
I am a student of our university, who often spend my spare time in our library. Generally speaking, our library provides quite good service. However, I still have some suggestions for you to upgrade the quality of your service.
To begin with, I would like you to prolong the open time. In the daytime, most students are having classes. To continue, some books are too old/ are out of date. It would be better if you could replace them with updated materials.
I sincerely hope to have a comfortable library. And I would be highly grateful if you could take my suggestions into consideration.

亲爱的先生或女士：
我是我们大学的一名学生，我的业余时间经常在图书馆度过。总的来说，我们图书馆的服务很好。不过，我仍有一些建议供您提高服务质量。
首先，我希望你们延长开放时间。在白天，大多数学生都在上课。为了继续，有些书太旧／过时了。如果你能用最新的材料替换它们，那就更好了。
我真诚地希望有一个舒适的图书馆。如果您能考虑我的建议，我将不胜感激。
I am a frequent user of our library. First, I would like to express my sincere gratitude to you as the library offers great help to us. I am writing this letter in purpose of rendering some suggestions to improve the quality of your service.
Firstly, you'd better arrange an inquiry desk at the circulation hall so that students could go through the procedures more efficiently. Secondly, the light in some corner is not so bright that we cannot look through books conveniently. Lastly, the amount of books can hardly meet our demands. So, I suggest our library will be able to make efforts to collect more popular and famous books. Besides,some outdated journal should be updated in time so as to bring new fresh air to us.
Thank you for taking time reading this letter and I hope you will find the proposals practical. Your prompt attention to my advice would be highly appreciated.
Yours Sincerely,
