Last year, a tragedy happened in Fudan University, a postgraduate was poisoned by his classmate and died, now more than a year has passed, his classmate who killed him got caught and the law declared him to carry the dead penalty. The murder was so regretful that he made apologize to both parents and the society for the negative effect he had caused. Dead penalty is so brutal, but the murder deserves, we must learn the lesson. When we get angry, we should not think about punishing others, we must calm down and have a talk to others, so that the problem can be fixed, or we will make the unforgettable mistake. Study is important, but we should not ignore the cultivation of moral and personality, the society need the person who is talented and kind-hearted. The poison case is nearly over, while its lesson is never over. 去年，復旦大學發生了一起悲劇，一名研究生被他的同學投毒，最終死亡，如今一年多過去了，殺害他的同學被抓起來，法律宣判他爲死刑。犯人很後悔，向雙方父母和社會道歉，爲了他給社會帶來的負面影響。死刑很殘酷，但是犯人死得其所，我們必須要學到教訓。當我們生氣，不應該想着懲罰別人，必須要冷靜下來，和別人談一談，這樣問題才能得到解決，不然就會犯下不可原諒的錯誤。學習很重要，但是我們不應該忽略道德和品性的修養，社會需要的是有才華和熱心腸的人。投毒案將要告一段落，然而教訓卻不會停止。
