第129期:伟大的老师对学生说过的话

 　　Do you understand what i taught you? If you do, say you do, if you do not, say you do not. Only then you are an intelligent man.

　　1. 知之为知之，不知为不知，是知也。

　　Confucius said:I will not instruct my students until they have really tried hard but fail to understand. If i give them on instance and they cannot draw inferences from it, i will not teach them anymore.

　　2. 子曰：不愤不启，不悱不发。举一隅不以三隅反，则不复也。
