阅读下面短文，根据短文内容，在回答所提问题的句子中填上恰当的词。每空一词。
Many people go to school for an education. They learn languages, history, science subjects and mathematics. Others go to school to learn a skill（技能）.So that they can make a living. School education is very important and useful. Yet no one can lean everything from school. A teacher, no matter how much he knows, cannot teach his students everything they want to know. His job is to show his students how to learn. He teaches them how to read and how to think .So, much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to learn some facts or formulas（公式）by heart. It is quite easy to learn a certain (某个) fact in history or a formula in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientists ,such as Newton, Galileo and Einstein didn't get everything from school, but they were all successful. They invented so many things. The reason for their success is that they knew how to study. They read books that were not taught at school. They worked hard all their lives, wasting not a single moment. Above all, they knew how to use their brains(大脑).
