听力题 W: Jim, thank goodness, you''ve arrived! The class presentation started half an hour ago. And I was just beginning to panic! M: I''m sorry I''m late, Ellen. This morning has been a real mess. I didn''t think I was able to make it here at all. W: Why are you late? Our whole presentation depends on the graphs you''re holding. M: Yes, I know. I''ll tell you about it later. First, let''s see how we''re doing for time. Two groups are still ahead of us, I think—the presentation on the rights of the consumer and the analysis of the stock market. That means I''ve got about thirty minutes to warm up. W: You do look cold! What happened? M: I''ve been standing outside in arctic temperature 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 under normal conditions. M: But the bus was delayed because of the weather. And when I stepped into a drug store to call home for a ride, the bus went by. As luck would have it, there was no one at home, so I had to wait another 45 minutes for the next bus. W: That''s Murphy''s Law, isn''t it? What was it he said? If anything can go wrong, it will. Well, we''ve still got twenty minutes to gather our wits together. M: We''d better stop talking. People are turning around and looking at us.
