Now you'll hear the two long conversations.
Conversation One
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 for 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 elsewhere. Yesterday, over a hundred students signed up.
M: Well, what is it?
W: It's an experimental course. I registered for child psychology. [19]All I have got to do is watch a twelve-week series of televised lessons. The department shows them seven different times a day and in seven different locations.
M: [19]Don't you ever have to meet with the 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 non-traditional to me. [20]But I guess it makes sense, considering how many students have jobs. It must really help with their schedules, not to mention how it will cut down on traffic.
W: You know, last year my department did a survey and found out that 80 percent of all psychology majors were employed. That's why they came up with the program.
M: [21]The only thing is: doesn't it seem impersonal though? I mean, I 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. But I'll be curious to see how it works up.

Questions 19 to 21 are based on the conversation you have just heard.
19. How was the distance-learning course different from traditional courses?
正确答案：A
解析：女士说：“我必须做的只是观看12周的电视课程。”男士问：“你不需要和老师见面吗？”女士回答：“是的。”因此答案为A。由选项可猜测题目可能是问学校教育方面的情况。B和C选项都是利用原文所说“一天播放几次……在不同的地方播放”而制造的干扰项，注意不要对原意进行主观臆断和联想。
20. What is the major advantage of the distance-learning course according to the conversation?
正确答案：C
解析：男士说：“不过鉴于很多学生有工作，这种方法很有意义。它真的在他们对时间的安排方面有所帮助，更不用说减少交通问题了。”因此答案为C。It选项题，所有的内容都是正面的，故题目询问的是it的好处。新鲜事物的出现总是有原因的，而原因常为考点。But后面的内容是听音关键。
21. What does the man think is the disadvantage of distance learning?
正确答案：B
解析：男士说：“不过唯一的问题是：这种教育不会缺少个人的东西了吗？我的意思是我最怀念课堂讨论和听听别人的想法。”因此答案为B。It选项题，都是负面的内容，故题目询问的是it的不足。利弊两方面，常为考点出处。
