上初中的时候,我的班主任是个新毕业的大学生,面对调皮捣蛋的学生们,很多时候只是讲道理。我记得有一次又有调皮的男生犯错了,她在黑板上写了“知耻而后勇”五个字,什么用意呢?当时真是不太懂。 When I was in junior high school, my class teacher was a newly graduated college student. In the face of mischievous students, most of the time it was just reason. I remember once again naughty boys made a mistake, she wrote “black and brave courage” five words on the blackboard, what purpose? At that time really do not understand.
