SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文： We all scream for water when thirsty. (15[A]) But do you know in very hot, dry weather plants also make faint sounds— as if they're crying out for help？
You see, in a plant's stem there're hundreds of "water pipes" that bring water and minerals from the soil all the way up to the leaves. As the ground turns dry, it becomes harder and harder for the plants to do this.
In severe droughts, plants have to fight to pull out any water available. Scientist Robert Winter has found out that when it is really bad their water pipes snap from the tension like rubber bands. When that happens, the whole plant vibrates a little. The snapping pipes make noises 10,000 times quieter than a whisper.
Robert knows that healthy, well-watered plants are quiet. (16[D]) He also knows that many insects prefer attacking dry plants rather than healthy plants. How do the insects know which are healthy plants and which are not？ Robert thinks that the insects may listen for the plants that cry. And then they may buzz in to kill.
To test his theory, Robert is using a device that can imitate plant cries. He attaches it to a quiet, healthy plant so the plant sounds thirsty. Then he watches insects lo see if they attack more often than usual.
If he is right, scientists could use the insects' ability against them. (17[D]) They could build traps that imitate crying plants. So when the insects buzz in to eat, they won't buzz out.
What do plants do when they are thirsty？
听力原文： (24[A]) Northern Ireland peace talks resumed yesterday with negotiations under orders from the US Chairman George Mitchell, former US Senator, (23[C]) to stop haggling and get down to the business of solving the worst violence in the province,
"The time has come to get down to serious negotiations and not to waste your time on full stops and commas. There is an urgent need for this process to proceed." George Mitchell said.
The talks, launched with fanfare by the British and Irish governments in June 12, started, however, without representatives of the key players, the IRA guerrillas fighting the British rules.
Who is George Mitchell？
听力原文：Man: Hi, I heard you are looking for a different apartment.
Woman: Yeah, the place I am in is really terrible.
Man: It was OK when I was there.
Woman: (7[D])The boiler keeps breaking and when it does, (9[A])we lose the heat for several days at the time.
Man: Why does not the owner replace it？
Woman: Well, she said it's cheaper to keep fixing it. She is a nice enough person, just sort of stingy in any case. I'm sick of being cold.
Man: Can you get your deposit back if you move？
Woman: If I give a 2-month notice, I can get the whole thing back.
Man: So what kind of place are you looking for？
Woman: I think I'll try to get into one of those high rises (8[A])near the university. There is nothing really special but at least they are new and functional.
Man: I heard those buildings are pretty noisy. The walls are thin and you can hear everything going on in the other apartment.
Woman: Oh. That will never do. (10[C])I need some place quiet to (8[A])finish my Thesis. I guess I'll have to look at some more ads. Maybe new isn't necessarily better.
Man: Why don't you try some of those apartment at Windsor？ They're supposed to be nice.
Woman: Oh, aren't they awfully expensive？
Man: Not really. The problem with being out there is the bus doesn't run that way.
Woman: That definitely won't be a problem. I can afford a car right now.
What is wrong with the woman's current apartment？
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：George: (l[B]) Excuse me. Are you going to buy concert tickets？
Dora: Yes, I am. So are all these people in front of me.
George: Have you been here long？
Dora: About 45 minutes. I've moved forward a total of about 3 feet in that time.
George: You are kidding.
Dora: Not at all. There was a couple up ahead of me who got so disgusted they finally gave up and left. They said they'd been waiting for more than an hour.
George: Terrific. Does any one know what's causing the delay？
Dora: If so,(2[D]) no one has let us know. It could be that there aren't enough people selling tickets this afternoon. Or maybe their computer is down. I'm sure the concert hasn't been cancelled.
George: I just hope they don't run out of tickets before I get up there.
Dora: That really would be annoying, wouldn't it？
George: I guess I should have come before lunch. Or has it been like this all day？
Dora: Apparently it has. In fact, before I came I tried calling to charge my tickets over the phone, just to avoid this long wait. But they are not taking phone orders, or checks, or credit cards. It's cash or nothing, and you have to come in person.
George: Well, there are two more hours before the tickets office closes.(3[B])Tickets for a good concert are worth waiting for. So I think I'll just make myself comfortable.
What is the relationship between the two speakers？
