单选题

单选题 Were there a lot of people at the lecture? [A] Yes, there was a big audience. [B] No, only one-third of the seats were occupied. [C] Yes, buy nearly 30% left after the short rest.

【正确答案】 C

【答案解析】[听力原文]15-17 W: Did a lot of people attend the lecture? M: Well, yes and no. W: What do you mean? M: You see, the classroom was quite full at the beginning. Almost all the seats were occupied. But after the short rest, almost one-third of the audience left. W: Terrible! That was a very rude thing. I should have been there. I had told the students to behave themselves. I do hope Professor Black was not angry. M: What do you mean? He wasn't even there. W: What? Professor Black did not come? M: No, his lecture is Thursday next week, not this Thursday. W: Oh, yes, of course. How silly of me! 在第一轮对话中女士问参加讲座的人多不多，得到了男士的肯定答复。而在第二轮对话中，男土的最后一句指出：...almost one-third of the audience left，即在中途休息时三分之一的听众都走了。结合这两个方面可知应选[C]。

单选题 Who gave the lecture this Thursday? [A] Professor Black. [B] The woman speaker. [C] They didn't mention his or her name.

【正确答案】 C

【答案解析】在第三轮对话中女士最后一句提到她希望Black教授不要生气(表明她以为举行讲座的是 Black教授)，男士则说Black教授根本不在那里，说明讲座不是Black教授作的。而在后面的对话中他们也没有提及到底是谁作了这次讲座，故答案是[C]。

单选题 What did the woman mean by saying "How silly of me".? [A] She meant it was silly of her not to attend the lecture. [B] She meant it was silly of her to blame the students. [C] She meant it was silly of her to mix up the dates of the lectures.

【正确答案】 C

【答案解析】由前面两题的分析可以看出，女士误以为讲座是Black教授作的，其实不是。在第四轮对话中，男士指出女士把日期搞错了，所以女士才说“How silly of me”，故答案是[C]。
