人们常用“一问三不知”来嘲笑不学无术之人。其实,嘲讽他人者未必知道“三不知”的含义。“三不知”最早出自《左传》。鲁哀公二十七年,晋荀瑶率师围郑,荀文子认为未了解敌情,不可冒进。他说:“君子之谋也,始、中、终皆举之,而后入焉。今我三不知而入,不亦难乎?”由此可见,“三不知”的本意乃是对某事的开始、经过、结局不了解,并非是对众多问题的不了解。现已引申为不学无术。 People often use “one asked three do not know” to ridicule those who do not learn without skill. In fact, people who ridicule other people may not know the meaning of “three unknown.” “Three unknown” earliest from “Zuo Zhuan.” Twenty-seven years of grief, Jin Xinyao rate led by Cheng, Xun Wenzi that did not understand the enemy, can not take advantage of. He said: “The idea of ​​a gentleman is also raised at the beginning, the end, and the end, and then into Yan. Now it is not difficult for me to come in without knowing anything about it.” Thus it can be seen that the intention of “three unknown” is the beginning of something After the end, do not understand, not a lot of problems do not understand. Has been extended to not learn without skill.
