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 (科学家) , such as Edison,
Newton, Galileo a Einstein. didn't learn everything from school. They learned a lot of knowledge
outside or in practice(实践) 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
teacher with rich experience (经验) 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 (能力) of how to use knowledge, it means the teacher
has learned lots of  knowledge himself(or herself). The success(成功)in learning shows he or she knows
how to study.
