【答案解析】[解析]
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]。
