Dear Mr Wang,
Knowing that our library is going to buy books, I’d like to give some suggestions.
What we need most are popular science books. Usually popular science books explain basic principles of nature in a simple and interesting way. They help us understand science subjects better and arouse our curiosity about scientific discoveries.
In addition to reading for knowledge, we read for fun and inspiration. That is why I recommend another category of books: literary. Classic works, written by masters, present great thoughts through fascinating stories and language. They not only offer us joy and excitement, but also encourage us to think critically.
I’ll be glad if you can consider my recommendation.
