【正确答案】 C

【答案解析】[解析] 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。
