Dear Miss Wang,
Knowing that our library is going to buy books, I'd like to give some advices.
Popular science books is what we need most. Usually popular science books explain basic principles of nature in a simple and interesting way. They helped us understand science better and arouse our curiosity scientific discoveries.
In addition to read for knowledge, we read for fun and inspiration. That is why I recommend other category of books: literary books. Classic works, written by masters, present great thoughts through fascinated stories and language. They not only offer us a joy and excitement, but also encourage us to think critical.
I'll be glad whether you can consider my recommendation.
Yours sincerely,
Leo
