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. As 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 shading the 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 whyis still unexplained."
M: Some squid are really huge. Can you imagine something that big ifit still had a shell?
W: Actually, it’ s because they lost their shells that they could evolve to a bigger size.
M: Make 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 have 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 form of sea life.
C、The study of marine shells.
D、Survival skills of sea creatures.

答案 B

解析 主旨题。本段长对话主要谈论的是sea life。重点谈了squid(乌贼鱼)与octopus(章鱼)。这两个词比较陌生,连谈话的人都觉得它strange。但从sea life(选项中已列出)中可以推断出它们是两种海洋生物即可。
