第五天：BOOKS 书籍

As is well known, books teach us to learn life, truth, science and many other useful things. They increase our knowledge, broaden our minds and strengthen our character. In other words, they are our good teachers and wise friends. This is the reason why our parents always encourage us to read more books.

Reading is a good thing, but we must pay great attention to the choice of books. It is true that we can derive benefits from good books. However, bad books will do us more harm than good.

如众所周知，书籍教我们学习人生，真理，科学以及其它许多有用的东西。它们增加我们的知识，扩大我们的心胸并加强我们的品格。换句话说，它们是我们的良师益友。这是为什么我们的父母终是鼓励我们要多读书的理由。
