School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher’s 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 a formula by heart. It is actually quiet easy to learn a certain fact in history or a formula(公式) in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientist, such as Einstein, Newton and Galileo, didn’t get everything from school. But they were all so successful and invented so many things for men. They worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.
