A、The man and the woman have the same opinion about the class discussion. B、It is usually too noisy to bear the class discussion

M: Professor White is really into class discussion. Almost in every of his class he would organize class discussion. To be honest, I’m fed up with it.
W: Really? Don’t you feel it enjoyable and quite beneficial?
M: No, I just feel it’s a waste of time.
W: I can’t see eye to eye with you. No matter what you think, I still believe class discussion is a good way of teaching and learning. As you know, class discussion can get us students more involved in what is being studied rather than sit there and listen all the time. We have a chance to speak our minds and share what we know about the subjects. Don’t you feel the same way?
M: Well, in a way what you said is true, but I’d rather listen to what the professor knows about the subjects, for he is expected to be better informed. I don’t think there is any point in wasting our time listening to other students who are as ignorant as us.
W: We may be ignorant in many aspects compared to the professor. But our opinions and experiences are also worth listening to and learning from. As the proverb goes, four eyes see more than two.
M: Sure, I understand many hands make light work. But some students are often dominant and aggressive in the discussion and do not respect others’ right to speak. I hate those self-important and irritating fellows.
W: I admit there are such moments in class discussion. But we should do justice to class discussion though some students fail to behave themselves and focus on the topic.
