【正确答案】 B

【答案解析】[听力原文]14-17 W: Jim, thank goodness you've arrived. The class report started half an hour ago. And I was just beginning to worry. M: I'm sorry I'm late, Ellen. This morning has been a real mess.

First, let's see how we're doing for time. Two groups are still ahead of us, aren't they? The re- port on the rights of the consumer and the analysis of the stock market. That means I've got about 20 minutes to warm up. W: You do look cold. What happened? M: I've been standing outside in cold temperatures for over an hour waiting for a bus. W: Over an hour? But I thought your apartment was only a ten-minute bus ride to campus. M: Under normal conditions, but the bus was delayed because of the weather. And when I stepped into a drugstore to call home for a ride, the bus went by. As luck would have it, there was no one home so I had to wait for another 45 minutes for the next bus. W: That's Murphy's law, isn't it? What was it said? "If anything can go wrong, it will." Well, we've still got 20 minutes to gather our wits together. M: We'd better stop talking. People are turning around and looking at us
