物理学中有这样一句：“同性相斥，异性相吸。”自己学物理的时候，压根儿就没有真正理解它的含义，直至今日，做了班主任的我终于发现了它的奥妙所在。把这物理中的定理运用到初中学生中，确实很符合，也让我这位青年班主任感受到其威力。初中生正处在一个激烈，动荡的阶段， In physics, there is such a sentence: “Same sex repulsion, the opposite sex attracts.” When he learned physics, he did not really understand the meaning of it. Until today, I had finally found my masterpiece in the class teacher. The application of this theorem in physics to junior high school students is indeed very consistent, and it also made my youth head teacher feel its power. Junior high school students are in a fierce, turbulent stage.
