听力原文：Harry: What do you think of Professor Potter’s course, Jane? Jane: Not much. Harry: Why, what’s wrong with it? Jane: Oh, I don’t know. It’s just that he overloads it with details. That course he gave on town planning last year. It was just the same -- a load of details, which you could have got from a book anyway. There was no overall... Harry: No general overview you mean? Jane: Yes. I suppose you could call it that. I couldn’t see the town for the buildings. Harry: But you' ve got to have details in this kind of subject. Anyway I think he's good. You take his first lecture for in stance. I thought that was very interesting, and not at all over-detailed. Jane: Well, he starts off all right, but then he just piles on the details. Harry: Now you' re exaggerating. Jane: Well, the way he dealt with the western developments, that wasn’t bad, I suppose. Harry: You seem to have got something. Perhaps Potter is a little disorganized, but I think he's good. Jane: Do you really think so? Harry: He does do most of his teaching to the postgraduates. He only does the one undergraduate course each year. After all, I think he tends to forget where he is. He starts off being nice and general and then tries to cram in a bit toe much specialized information. Jane: The main thing I object to is this lack of direction. What does Jane think of Potter’s course?
