What personal qualities should a teacher possess？ Probably no【B1】people would draw up exac

tly similar lists,【B2】I think the following would be generally accepted.

First, the teacher's【B3】should be pleasantly live and attractive. This does not exclude people who are【B4】plain, or even ugly, because many such people have great personal charm. But it does exclude such types as the proud, selfish, and cynical. It also excludes all of dull or purely【B5】personality. I still【B6】the saying that "School children【B7】more from boredom(乏味) than from violence."

Secondly, it is not merely necessary but【B8】for a teacher to have a genuine【B9】to listen to the minds and【B10】of students. Closely【B11】with this is the capacity to be tolerant—not indeed, of what is wrong, but of the immaturity of human nature which causes people, especially children, to make【B12】.

It means that he will be【B14】of his moral【B15】and limitations and will have thought about and decided upon the moral【B16】by which his life shall be guided. What I'm going to say next is that a teacher should be a bit of an actor. That is part of the【B17】of teaching, which demands that every now and then a teacher should be able to put on an【B18】—to enliven a lesson, correct a fault, or【B19】praise. Students,【B20】young children, live in a world that is rather larger than life.
