听力原文：W: Good evening, Mr. Brown, and welcome to the program.
M: Thank you!
W: I wonder if you could tell listeners more about the work you do？
M: Certainly.
W: Mr. Brown, I gather that you work for a company developing software for reading electronic books？
M: That is so.
W: Do you think there is much future in that7
M: Well, people buy music online—so why not books？
W: You have to read electronic books on a machine, don't you？

听力原文：M: What do you think of Professor Potter's course, Jane？
W: Not much.
M: Why, what's wrong with it？
W: Oh, I don't know. It's just that he overloads it with details. The 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 ...
M: No general overview you mean？
W: Yes. I suppose you could call it that. I couldn't see the town for the buildings.
M: But you've got to have the details in this kind of subject. Anyway I think he's good. You take his first lecture for instance. I thought that was very interesting, and not at all over-detailed.
W: Well, he starts off all right, but then he just piles on the details.
M: Now you're exaggerating.
W: Well, the way he dealt with the Western developments, that wasn't bad, I suppose.
M: You seem to have got something. Perhaps Potter is a little disorganized, but I think he's good.
W: Do you really think so？
M: 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 too much specialized information.
W: The main thing I object to is the lack of direction.
What does Jane think of Potter's course？
A．Very good.
B．Too general.
C．Clear and interesting.
D．Meticulous and too specialized.
