     Students learn their lessons in class. In class teachers teach them. Students sit in the classroom listening.

 This is a way of learning. Is this the only way for students to learn something? Of course not. There is

 another way to learn. That is, students can teach themselves. For example, if you can not remember

 something when you are doing your homework, you can look at your book to find the answer. This is a

 way to teach yourself. And it is not a difficult thing. We can do this at any place and at any time.

     How do you teach yourself? The first thing you must do is reading. Read something you are interested

  in, or you have to read. The second is that you must ask yourself questions. If the question is something

 you don't understand or you want to know more about, you can write down these questions. The third is

 to answer the question yourself by thinking hard, by reading the text or other books, and sometimes by

 asking other people. This is the way of teaching yourself. And you must do this all by yourself. If you keep

  doing like this for a long time. You are sure to succeed (成功) in your study.
