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 books. 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.
【亮点说明】短文用了一些短语和句式增加了文章的色彩，如：would like to do；help sb do sth；not only...but also;encourage sb to do sth;That is why…等，还用了一些连词使句子结构复杂化，如：What we need most are popular science books这里what引导的主语从句；That is why I recommend another category of books：这里why引导的表语从句；I’ll be glad if you can consider my recommendation.这里是if引导的条件状语从句。
