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?
正確答案：C
解析：四個選項都是關于They的，從same，both來看，似乎在問他們“一同”、“都”怎么樣。推斷題。根據男士一開始自我介紹時所說的“It's Bill Parker from your calculus class，”可知答案為C。對話開頭常設考點。
20. What can be inferred about the campus literary magazine?
正確答案：B
解析：推斷題。當男生提到雜志The Signal時，女士反問了一句“The what?”這表明女士對雜志不熟，所以她才道歉，并且解釋說自己今年剛轉學來這里，由此可推出答案為B。A、D來提及，C與對話內容相反。反問處必有玄機。
21. What is Bill going to do after dinner?
正確答案：D
解析：四個動詞原形預示著將疑問“干什么”或“為什么”。細節題，Bill晚飯后將干什么？Sue建議兩人晚飯后見面，Bill回答說“Uh, that's bad for me—I have a meeting for The Signal,”據此，選D?！癠h”語氣詞出現，后面的內容十分重要。B、C是女士打算做的事情，均不正確。在長對話的測試里，細節題是大量存在的，而且不好對付，因為既要考你聽懂了沒有，還要考你的記憶力，所以要適當做筆記。
