【答案解析】[听力原文]17-20
M: You're going to wear out that typewriter.
W: Oh, hi. What are you doing here at fills time of night?
M: I should ask you that question. Do you have any idea what time it is?
W: About ten or ten-thirty?
M: It's nearly midnight.
W: Really? I didn't have any idea it was so late.
M: Don't you have an early class tomorrow morning?
W: Yes, at seven o'clock. My spare-time class, the students who go to work right after their lesson.
M: Then you ought to go to bed. What are you writing, anyway?
W: An article I hope I can sell.
M: Oh, another of your newspaper Nieces? What's this one about?
W: Do you remember that trip I took last month?
M: The one up to the Amazon?
W: Well, that's what I'm writing about -- the new highway and the changes it's made in the Amazon Valley.
M: It should be interesting.
W: It is. I guess that's why I forgot all about the time.
M: How many articles have you sold now?
W: About a dozen so far.
M: What kind of newspapers buy them?
W: The papers that carry a lot of foreign news. They usually appear in the big Sunday editions where they need a lot of background stories to help fill up the space between the ads.
M: Is there any future in it?
W: I hope so. As a matter of fact, there's a chance that I may sell this article to a news service.
M: Then your story would be published in several papers, wouldn't it?
W: That's the idea. And I might even be able to do other stories on a regular basis.
M: That would be great. But you'd better quit for the night now. Remember your spare-time class students?
W: All right. I'll stop, just as soon as I finish this paragraph.

第二个话轮中双方谈到了说话时的时间，而在第三个话轮中男士一句指出：It's nearly midnight(快到午夜了)，因此答案是[C]。注意ten是上一个话轮中女士用问句提出的时间，她并不确定。

[A] About 20. [B] About 12. [C] About 6. [D] None.
【正确答案】 B
【答案解析】本题考查的实际上是考生对于习惯表达的理解。在第九个话轮中男士询问女士卖出了几篇文章，女士回答说：About a dozen so far，其中的a dozen指的是12篇，因此本题答案是[B]。
单选题 What will the woman be doing tomorrow morning?
[A] Teaching her students. [B] Writing the article about her trip.
[C] Studying for an exam. [D] Travelling to the Amazon.
【正确答案】 A
