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.
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。
Reading is a good thing, but we must pay GRE atattention 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.
读书是一好事，但我们必须多加注意书的选择。不错，我们能从好书中获得益处。然而，坏书却对我们有害无益。
