听力原文：M: Hi, Lynn, I saw you at registration yesterday. I sailed right through, but you were standing in a long line.W: Yeah, I waited an hour to sign up for a distance-learning course.M: Distance learning? Never heard of it.W: Well, it's new this semester--it's only open to psychology majors. But I bet it'll catch on else where. Yesterday over a hundred students signed up.M: Well, what is it?W: It's an experimental course. I registered for child psychology. All I've got to do is watch a twelve week series of televised lessons. The department shows them several different times a day and in several different locations.M: Don't you ever have to meet with your professor?W: Yeah, after each part of the series I have to talk to her and the other students on the phone, you know, about our ideas. Then we'll meet on campus three times for reviews and exams.M: It sounds pretty nontraditional to me, but I guess it makes sense, considering how many students have jobs. It must really help with their schedules--not to mention how it'll cut down on traffic.W: You know, last year my department did a survey and they found out that 80 percent of all psychology majors were employed. That's why they came up with the program. Look, I'll be working three days a week next semester, and it was either cut back on my classes or try this out. M: The only thing is... doesn't it seem impersonal, though? I mean, I'd miss having class discussions and hearing what other people think.W: Well, I guess that's Why phone contact's important. Anyway, it's an experiment. Maybe I'll end up hating it.M: Maybe, hut... I'll be curious to see how it works out.(20)A．On television.B．At registration.C．In class.D．At work.
