第2题
M: Well, to begin with, I was surprised to find out there was so much going on in bones. I always assumed they were pretty lifeless.
W: Well, that's an assumption many people make. But the fact is bones are made of dynamic living tissue that requires continuous maintenance and repair.
M: Right. That's one of the things I found so fascinating about the article the way the bones repair them selves.
W: Ok. So can you tell us how the bones repair them selves.
M: Sure. See, there are two groups of different types of specialized cells in the bone that work together to do it. The first group goes to an area of the bone that needs repair. This group of cells produces the chemical that actually breaks down the bone tissue, and leaves a hole in it. After that' the second group of specialized cells comes and produces the new tissue that fills in the hole that was made by the first group.
W: Very good. This is a very complex process. In fact, the scientists who study human bones don't completely understand it yet. They are still trying to find out how it all actually works. Specifically, be cause sometimes after the first group of ,cells leaves a hole in the bone tissue, for some reason, the second group doesn't completely fill in the hole. And this can cause real problems. It can actually lead to a disease in which the bone becomes weak and is easily broken.
M: Ok, I get it. So if the scientists can figure out what makes the specialized cells work, maybe they can find a way to make sure the second group of cells completely fills the hole in the bone tissue every time. That'll prevent the disease from ever occurring.

听力原文：W: Is there such a thing as a typical shoplifter？
M: Uh, not really... But there are certain types most shoplifters fall into. Three types, I would say.
W: Tell me more about these three types.
M: Well... uh... people in the first type are what I call "the sudden impulse type". Doctors and psychologists call such people kleptomaniacs. They see something and just can't ... uh... help stealing it. The strange thing about this first type is that the people in it are often well off and could easily afford to buy the thing. Sometimes they don't even need it... and often they're emotionally disturbed in some way.., middle-aged women, for example, whose husbands have left them, or perhaps older men whose wives have recently died.
W: What about the second type？
M: Well, those are people who are really... "little thieves" They work alone, and know exactly what they want before they go into the store. These days a lot of them, but by no means all, are teenagers who steal things they can't afford. Leather jackets, watches, expensive cosmetics, things like that.
W: And the third type.'？ What kind of people do you find in the third type？
M: Ah, yes, they're what I call "the experts".
W: Why？
M: Well, first of all, because they're highly organized. And secondly because they do it for a living. They usually operate in groups of three or sometimes four, and they're extremely difficult to catch.
W: Can they make a lot of money that way？
M: Oh, yes. They're very well off, believe me... much better off than a store detective..., or even a journalist!
How many kinds of shoplifters are mentioned in the dialogue？
A．2
B．3
C．4
D．5

听力原文：M: Sue, how do you decide what time to show a program？
W: Well, it depends on the program. We look for different types of programs for different times of the day. For example, at breakfast time, we show short news and interview program. People don't watch for long in the morning, so everything must be very short.
M: And what happens later？
W: Well, we plan programs around what people are usually doing. We have to think about prime time.
M: Prime time--what's that, exactly？
W: Prime time is the time when the largest number of people is watching TV. In this country, that's from 6 p.m. to 11 p.m. Most people have come home from work and they're relaxed.
M: And, what programs do you show then？
W: We usually show new TV series which most people like. You see, before 9 p.m., we try to show programs for everybody.
M: Oh, I see.
W: And we also need to think about the ratings.
M: Can you tell us about that？
W: Well, the ratings tell us how many people are watching each program.
M: Oh, how do you know that？ You can't ask everybody!
W: No, of course not. Well, most TV stations buy information from an audience research company. They ask a small number of people -- perhaps a few hundred-- to keep a record of what they watch. Then that gives them an idea of what everybody watches.
M: Are ratings very important？
W: Very important. Our television company is commercial. We make money by selling advertising time. If our ratings are high, we can ask a higher price for advertising time. So we're always trying to increase our ratings.
M: So in a way, the advertisers Control what you show on television.
W: Um, not directly, but in a way, yes.
