书是人类进步的阶梯,要获得知识当然要读书。古人曰:“学者先要会疑。”“尽信书不如无书。”就是说读书要有怀疑精神,不要随便盲从或迷信书本。许多学生对书中的知识确信无疑,他们认为著书的人都是大学问家,怎会有错误呢?因 The book is a ladder of human progress, of course, to acquire knowledge to read. The ancients said: “Students must be suspicious.” “That is not as good as a book without a letter.” This means that you must be skeptical about reading, and do not blindly or superstitionally read books. Many students are undoubtedly convinced of the knowledge in the book. They think that the person who wrote the book is a college student. How can there be mistakes?
