we go to school for education. we learn maths, english,chinese,  physics  and  other  subjects.  school  education  is necessary and important. however, no one can learn everything from school. even a very good teacher can not tell his students everything they want to know.   　　edison didn't have much schooling, but he became a famous scientist. it doesn't mean that school education is not important.he knew how to learn new things by himself.  as a matter of fact, many things can be learned outside school by the students themselves.   　　so we should learn how to learn at school.
