SECTION A CONVERSATIONS
Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.
听力原文：M: I really appreciate you're feeling 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 shattering 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: Make sense. But some are really huge. I've read about fishermen that caught squid that weight 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 22 yards long. Its eyes were 18 inches across. Can you imagine？
M: Reminds me about all those stories of sea monsters.
W: Doctor 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.
