看到吴非老师在随笔中感叹:“在当今中国,我越来越认识到坚守常识的艰难,特别是作为一名普通教师,理智和情感每时每刻都会遭到腐蚀或挑战。”(《由顾黄初的书房说起》)我不禁想起读研究生时,导师不止一次地对我们说:“我没有什么高深学问,我所能教你们的不过是些常识。” See Wu Wu teacher laments in his essay: “In today's China, I increasingly recognize the hardships of common sense, especially as an ordinary teacher, intellect and emotion will be corrupted or challenge all the time. (Speaking from the study of Gu Huangchu) ”I can not help but think of me when I was a graduate student. My teacher said to me more than once:“ I have no profound knowledge and I can only teach you some common sense. ”"
