Now you'll hear the two long conversations.
Conversation One
W: Hello?
M: Hi, Sue. [19]It's Bill Parker from your calculus class.
W: Oh sure. How are you?
M: Fine, thanks. Listen, I'm working on our assignment and I can't seem to figure out the last problem and, uh... the teaching assistant's out of town, so I was wondering if you could help me.
W: Well, I did the last one, but I'm not sure it's right.
M: At least you finally figured it out-I didn't get past the first three steps. Would you like to have coffee with me? We could go over all of the problems.
W: That's a good idea-I need help with number five. I'm completely lost on that one.
M: Are you free now?
W: I have swimming practice in a few minutes and then I have to study for a biology exam-but I could meet you right after dinner.
M: [21]Uh, that's bad for me-I have a meeting for The Signal.
W: [20]The what?
M: [20]The Signal-you know, the campus literary magazine. It comes out once a month.
W: [20]Oh, sorry-I just transferred here this year.
M: I'll give you a copy. In fact, I'll bring it when we meet... So, anyway, what about tomorrow... After lunch, maybe?
W: Great. See you around one.

Questions 19 to 21 are based on the conversation you have just heard.
19. How do the speakers know each other?
正确答案：C
解析：四个选项都是关于They的，从same，both来看，似乎在问他们“一同”、“都”怎么样。推断题。根据男士一开始自我介绍时所说的“It's Bill Parker from your calculus class，”可知答案为C。对话开头常设考点。
20. What can be inferred about the campus literary magazine?
正确答案：B
解析：推断题。当男生提到杂志The Signal时，女士反问了一句“The what?”这表明女士对杂志不熟，所以她才道歉，并且解释说自己今年刚转学来这里，由此可推出答案为B。A、D来提及，C与对话内容相反。反问处必有玄机。
21. What is Bill going to do after dinner?
正确答案：D
解析：四个动词原形预示着将疑问“干什么”或“为什么”。细节题，Bill晚饭后将干什么？Sue建议两人晚饭后见面，Bill回答说“Uh, that's bad for me—I have a meeting for The Signal,”据此，选D。“Uh”语气词出现，后面的内容十分重要。B、C是女士打算做的事情，均不正确。在长对话的测试里，细节题是大量存在的，而且不好对付，因为既要考你听懂了没有，还要考你的记忆力，所以要适当做笔记。
