M: I really appreciate your filling me in on yesterday’s lecture.
W: No problem. I thought you might want to go over it together. And, anyway, it helps me review. Hope you’re feeling better now.
M: I am. Thanks. So, you said she talked about squid.’? Sounds a little strange.
W: Well, actually, it was about the evolution of sea life -- a continuation from last week. The octopus and the squid descended from earlier creatures with shells. They survived by shedding their shells somewhere between 200 and 500 million years ago.
M: That’s a pretty long span of time.
W: I know. That’s what she said, though. To be precise. "Exactly when they emerged is uncertain …and why is still unexplained."
M: Some squid are really huge. Can you imagine something that big if it still had a shell?
W: Actually, it’s because they lost their shells that they could evolve to a bigger size.
M: Makes sense. But some are really huge. I’ve read about fishermen that caught squid that weighed over a ton. Did she talk about how that happens?
W: Not really. But she did mention some unusual cases. In 1933 in New Zealand they caught a squid…let’s see here… it was twenty—two yards long. Its eyes were eighteen inches across. Can you imagine?
M: Reminds me of all those stories of sea monsters.
W: Dr. Simpson thinks there are probably even larger ones that haven’t been found because squid are intelligent and fast—so they can easily get away from humans. Maybe some of those monster stories are true.

选项 A、Mating habits of squid and octopus.
B、The evolution of certain forms of sea life.
C、The study of marine shells.
D、Survival skills of sea creatures.

答案 B

解析 在四级长篇听力题中,常常会考到这类长文章。应对这类题目的方法之一是把文章中出现频率高的词汇和意思相近的词汇联系在一起进行思考,通过归纳与总结的方法找出这些词的共同点。例如,在这段文章里,把evolution,descend,survive,evolve等词放在一起进行思考,可以很容易地发现它所讨论的主题是关于生物进化的,因此选B。squid:鱿鱼;octopus:章鱼。选项A里matinghabits是指交配习惯。
