       School education is very important and useful. The students both learn  knowledge and get an

education. Yet,no one can learn everything from school. The scientists, such as Edison, Newton,

Galileo and Einstein, didn't learn everything from school. They learned a lot of knowledge outside

school or in practice by themselves. A teacher,even he knows a lot,can't teach his students everything.

      The teacher's job is to show his students how to learn, how to read, and how to think. A good

teacherwith rich experience in teaching can teach his students the methods ( = ways) of study.

Through these methods the students are able to learn and get a lot of things by themselves.

      Usually it is very easy for the students to remember some knowledge, but it is very difficult to

use it for problems. If a teacher really shows the students the ability to use knowledge, it means the

teacher has learned lots of  knowledge by himself ( or herself). The success in learning shows he or

she knows how to study.
