     Many people go to school for education. They learn language,history,politics,math and so on. Others go

to learn a skill so that they can find a job. School education is very important and useful. Yet, no one can learn

everything from school. A teacher can't teach his students everything. The teacher's job is to show students

how to learn. They teaches them how to read and how to think. So the students shall learn much more outside

school.

     It's always more important to know how to study by oneself than to remember some facts or formula

(公式). It is certainly quiet easy to learn a certain fact in history or a formula in math. But it is very difficult to

use a formula in working out a math problem. Great scientists before us didn't get everything from school.

Their teachers only showed them the way. The reason for their success is that they knew how to study. They

read books more than taught at school. They would ask many questions as they read. They worked hard all

their lives. Most important is that they knew how to use their brain. (大脑).
