W: George, where were you yesterday evening? I expected to see you at the concert.
M: Oh, I waited for you at the corner of Thomas Street. Then I looked for you at your flat, but the housekeeper said you were out.
Q: Why didn't they meet that evening?
正确答案：B
解析：概括总结题。本题要在听懂双方谈话的基础上，概括出他们没有见面的原因。女士在音乐厅等男士，而男士却在街道拐角等她，说明他们错过了彼此，故选B。原文中只有一个音乐会，所以A错；女士并没有去街角，所以C错；D正好与事实相反。

W: The place I've heard so much about is Los Angeles. The climate is pretty good. Year-round flowers, year-round swimming. How do you like it?
M: Well, the beaches are beautiful. But people there are terribly annoyed by the dirty air. I mean, the combination of fog, smoke and automobile exhaust. There is not enough wind to blow it away.
Q: What does the man think of Los Angeles?
正确答案：A
解析：BUT题。But后面的转折指出“洛杉矶的人们受到空气污染的烦扰”。故选A。也可以从后两句的解释中得出正确答案，fog，smoke and automobile exhaust（汽车尾气）肯定是和空气污染有关的。另外，最后一句中的it肯定指的是空气中的污染物，所以意思还是说空气受到了污染。因此也可以判断正确答案为A。
