A. so difficult    B. very difficult         C. so easy            D. very easy

 Many people go to school for education. They learn language, history, politics, geography, physics, chemistry and math. Others go to school to learn a skill so that they can make a living. 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 student everything they want to know. The teacher’s job is to show his students everything they want to know. In modern world, 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 memorize some facts or a formula （公式）. It is quite 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. Edison didn’t even finish primary school. But they were all successful. They invented so many things for us. The reason for their success is that they knew how to study. They read books that were not taught at school. They would ask many questions as they read. They did thousands of experiments. They worked hard all their lives, not wasting a single moment. Above all they knew how to use their brain.
