【正确答案】 D

【答案解析】[听力原文]
W: Recently I read a report about the higher education in Britain. It says that only about 10% of our students leave university without getting a degree.
M: That may be true. For me, I am not worried about failing but I am very anxious to get a good degree. My aim is to get a first-class honors degree in chemistry at Cambridge since I have a plan to take up a scientific post in industry. My criterion for choosing a good university is whether it has progressive ideas on education as well as its broader and more varied courses.
M: It wouldn't work. There will be too many different opinions. Some professors and lecturers are more interested in their own research than in helping students in their studies.
W: Well, there must be some brilliant scholars in the university such as yours.
M: Yes, I still go to classes as well as to lectures, but the most important person in my academic life is my tutor who in Cambridge is called a supervisor. I enjoy my weekly tutorials. My supervisor is an approachable man and he is always ready to talk to me about anything connected with my studies.
W: Haven't other universities now introduced some form of tutorial supervision like that at Oxford and Cambridge?
M: Yes, in fact, to be honest, there are universities which offer better courses and give better teaching in some subjects than either Oxford or Cambridge. I think that an Oxbridge degree still counts more with some employers than a degree from other universities. But most of them are now more concerned with the kind of degree than where it comes from.
W: Anyway, at our universities, the personal supervision and friendly relations with the teaching staff are especially good. The lecturer-student ratio is quite reasonable.
M: I am not so sure. But at least we are not over-crowded. I've heard that in some foreign universities lecture halls are packed so full that students have no where to sit.
