Many people go to school for education. School
education is very important and useful ,but no one can l
earn
everything from school. A teacher ,no matter how much he knows ,cannot teach
his student everything .His work is to show his students how to learn .He
teaches them how to read and how to t
hink
. So much more is to be learned outside school by students themselves.
It’s always more important to know how to learn
by oneself than to learn some facts or formulas (公式)by
heart. It’s quite easy to learn some facts in history or a formula in maths,

from school, but they were all successful. They invented so many things. The

outside school .They worked hard all their lives, wasting not a single moment.
The most important thing is that they know how to use their brains(大脑)。
