When the educational situation appears, the head teacher is very sensitive to the subtle situation, and his or her intuition tells him or her that he or she must respond quickly. Therefore, educational tact has strong adaptability and quick response ability, and can respond quickly when needed. At this time, wit can often help the building tilt and turn the tide. The key moment is caused by "machine", and the word "machine" flashes. Wit has situational adaptability and quick response ability because it can understand the meaning of what it sees, feel the importance and urgency of the situation, know what to do and how to do it, and can do something properly. This instant wit is the result of the synergy of perception and understanding, insight and intuition. As soon as a new English teacher came into the classroom, he wrote English on the blackboard. I accidentally wrote one letter less than "happened". A boy said, "Teacher, does the word OCCURRING have two R's?" The teacher pondered for a while and said, "Yes, you are right!" " "Then, she smiled cunningly and said," just to see you. The boy kept asking, "Will you teach us spelling this year?" Several students began to snicker, but the teacher retorted, "Oh, I wanted to keep this secret a little longer, but now I have to admit: I'm not perfect! But this certainly can't stop me from expecting you to be perfect. "Wit is a flash in the pan, but it is the result of a lot of experience accumulated at ordinary times.
