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.
What topic are the man and woman discussing？
听力原文：M: Hi, Sue. Where have you been？
W: Oh. Hi, Dan. I was just at the library. I have to hand in my biology paper tomorrow.
M: Tomorrow？ Oh, no! I thought it wasn't due till Monday.
W: Oh. Don't worry. It is due Monday. But I'm going away for the weekend and won't be back till Monday night.
M: Oh, where are you going？
W: California. We're having a family reunion. It's my grandmother's ninetieth birthday, so all the cousins and aunts and uncles are going. She planned the whole thing herself.
M: Wow. That's great. How many people will be there？
W: Around sixty. My family is big and spread up but we're pretty close. So have you started working on your biology paper？
M: Yeah. I'm doing it on bees and bow they're able to recognize whether another bee is related to them.
W: How can they tell？
M: They use their sense of smell. The sweat bees guard their nest this way. If another bee approaches the nest, the guard determines if the new bee is familiar. If it is, it's allowed to enter.
W: Interesting. Can other insects do this？ Well, the paper wasps can. Each wasp nest has a special combination of plant fibers and so the wasps that live there have a unique smell. Those two are the only kinds I've read about so far.
M: Well, you've still got time. It sounds like that the bees are picky about who comes to their family reunion.
What is the relationship between the speakers？
What do we mean by a perfect English pronunciation？ In one sense there are as many different kinds of English as there are speakers of it.【21】two speakers speak in exactly the same way. We can always hear differences【22】them, and the pronunciation of English varies a great deal in different geographical【23】. How do we decide what sort of English to use as a model？ This is not a question that can be【24】in the same way for all foreign learners of English.

We all associate colors with feeling and attitudes. In politics dark blue often means "tradition", and red means "social change". But blue can also mean sadness (I'm feeling blue), white is often for purity, although in China white is worn at weddings and black for funerals. Advertisers are aware of the importance of selecting colors according to the way people react to them. Soap powders come in white and light blue packets (clean and cold, like ice); cereals often come in brown packets (like wheat fields), but cosmetics never come in brown jars (dirty？).
Where do these ideas come from？ Max Luscher from the University of Geneva believes that in the beginning life was dictated by two factors beyond our control: night and day. Night brought passivity, and a general slowing down of metabolism; day brought with it the possibility of action, and increase in the metabolic rate, thus providing us with energy and initiative. Dark blue, therefore, is the color of quiet and passivity, bright yellow, the color of hope and activity.
In prehistoric times, activity as a rule took one of two forms: either we were hunting and attacking, or we were being hunted and defending ourselves against attack. Attack is universally represented by the color red; self-preservation by its complement green.
In Luscher's view, the association of colors with feeling and attitudes can be traced back to ______.
