Mao Dengsan, who teaches us, is very active in thinking, eloquent and loud, and his tutor is very famous. Teacher Ding belongs to that kind of thinking. I can also see from his lectures that he often makes some unusual remarks, but it is good for students, because they are all young people and have more languages. He hasn't given us a question yet, and the specific style is not clear. However, there are no special circumstances in which university teachers will not deliberately make things difficult for students, especially professional courses. Teacher Ding is very considerate. It shouldn't be difficult.

By the way, did the landlord take the postgraduate entrance examination? The life system of postgraduate entrance examination questions should be carried out according to the outline, and the proposition teacher will not improvise, but will vary from person to person. A teacher like Xiaoding is more flexible in estimating questions, and will not be very rigid. Reciting alone cannot completely solve the problem. Think more and be proactive.
