中学时,有一道物理测验题至今人仍然记忆犹新。记得当时班上没一个人答对的,把物理老师的嘴都气歪了。课堂上他冲着我们大声吼道:“这么简单的一道题竟然没有一个人答对,我都替你们感到害羞……”我们默默地被训斥了半节课。那道题的确很简单,问的是弹簧的弹性定律,只要答“在一定限度内弹簧伸长的长度与所承受的重力成正比”就算正确,但大家居然都把前面“在一定限度内”这几个字给忘了,结果被训得好不狼狈。 In high school, there is still a physical test questions still fresh in my memory. I remember when no one in the class was right, the physical teacher’s mouth angrily crooked. In class, he shouted at us: “There was not a single answer to such a simple question, and I was shy for you ...” We silently were scolded for half a lesson. That question is indeed very simple, asked the spring’s law of elasticity, as long as the answer “within a certain limit, the length of the spring elongation and the gravity is proportional to” “Even if the correct, but we actually have the front” within a certain limit " Forgotten these words, the results were well trained not embarrassed.
