【正确答案】 1、正确答案：A well-known passage quoted from Xueji(The Subject of Education), a chapter of the ancient book Liji(The Book of Rites), expresses the similar meaning: " when you learn, you will know your own deficiencies: when you teach, you will know where the difficulty lies. The awareness of deficiencies makes you examine yourself, and the realization of difficulties urges you to improve yourself. Hence, teaching and learning help each other. " This argument is irrefutable even in the present world. "A teacher is a student in the first place. "It is easier understood than admitted in the real life. Particularly, experienced teachers are quite reluctant to accept that dialectics, and their unwillingness does not seem totally groundless. Although Han Yu, one representative of feudal thoughts, proposed that "the student does not necessarily know less than the teacher, while the teacher is not definitely wiser than the student" , it was not practiced in the feudal times. On the contrary, teacher, with heaven and earth, the emperor and parents, is of a commanding position. After all, we accept it as a custom that the authority of teacher is inviolable. The new relationship between teachers and pupils should be"not being ashamed to learn from each other. "The two are equals in spite of precedence, and, as the saying goes, " whoever knows the truth can be a teacher" , which means whoever is learned is a teacher. The sage doesn"t limit himself to one particular teacher, and there is no routine way of teaching.
