听力原文：M: How is the energy content of food measured？
W: It's measured in calories. The calorie is defined as the heat energy needed to raise the temperature of 1 kilogram of water from 14.5 degrees centigrade to 15.5 degrees centigrade.
Q: What does the woman define？
(16)
A．The kilogram.
B．The energy content.

The event offender, scientists conclude, is the burning of coal, oil, synthetic fuels, and natural gas. These carbon-rich fossil (从地下采掘的) energy sources release an estimated five and a half billion tons of carbon into the atmosphere each year as colorless, odorless (无味的) CO2 gas.
The increased carbon dioxide is probably not a threat to health, since normal indoor levels of the gas can run 1000 parts per million or higher without apparent harm. But it could deeply affect the way the earth is heated by the sun. The sun's energy strikes the earth principally in the form. of visible light. As the earth heats up, it radiates this energy back into space, but at the much longer wavelengths of infra- red (红外线的) light, or heat. Carbon dioxide lets the visible light pass through, but absorbs energy at infra-red wavelengths. Thus, the more carbon dioxide in the atmosphere, the more the earth's heat is blocked from escaping --just as a blanket holds in the heat of a sleeper's body.
Some scientists think the greenhouse effect already has begun: average global temperatures have risen about one degree Fahrenheit in the past 90 years. Others argue that the rise could be due to the irregular change of natural temperature.
People have different opinions about ______.
A．why the concentration of gas is rising steadily
B．to what degree the greenhouse effect can affect us
C．whether CO2 has anything to do with the greenhouse effect
D．what measures should be taken to lower the carbon dioxide levels

听力原文：M: Hi Diana, mind if I sit down？
W: Not at all, Jerry. How have you been？
M: Good. But I'm surprised to see you on the city bus. Your car in the shop？
W: No. I've just been thinking a lot about the environment lately. So I decided the air will be a lot cleaner if we all use public transportation when we could.
M: I'm sure you are right. The diesel bus isn't exactly pollution free.
W: True. But they'll be running a lot cleaner soon. We were just talking about that in my environmental engineering class.
M: What's the city gonna do？ Install pollution filters of some sort on their buses？
W: They could, but those filters make the engines work harder and really cut down on fuel efficiency. Instead they found a way to make their engines more efficient.
M: How？
W: Well, there is a material called the confine oxide. It's a really good insulator. And a thick coat of it get sprayed on the certain part of the engine.
M: An insulator？
W: Well, yeah. Actually, what it does is to reflect back the heat of burning fuel. So the fuel will burn much hotter and burn up more completely.
M: So a lot less unburned fuel comes out to pollute tile air, right？
W: Yeah, and the bus will need less fuel. So with the savings on fuel cost, they say this will all pay for itself in just six months.
M: Sounds like people should all go out and get some this stuff to spray their car engines.
W: Well, it's not really that easy. You see, normally, the materials are fine powder. To melt it so you can spray a coat of it on the engine parts, you first have to heat it over 10,000 degrees and then, well, you get the idea. It's not something you or I be able to do ourselves.
(23)
A．A new fuel for buses.
B．The causes of air pollution.
C．A way to improve fuel efficiency in buses.
D．Careers in environmental engineering.
第5题
W: I recently read that in ten years we’ll be wearing clothes that change with the weather. So when it's cold, our clothes will warm up, and when it's hot, our clothes will cool off.
M: Oh, very funny! So we'll be wearing gigantic clothes with built-in air conditioners and heaters.
W: I'm being serious! Researchers have discovered a method of treating fibers with plastic crystals capable of storing and releasing heat as the temperature fluctuates. These treated' fibers absorb more heat than untreated fibers. Researchers are still working with this, but soon this process will be widespread.
M: That's fascinating. I didn't know that fibers had the capability of storing heat. How does that work？
W: These fibers work with the heat by rearranging their structures. The treated fibers move back and forth between two solid shapes.
M: I don't understand. What kind of shapes do they change into？
W: When the weather gets warmer, the crystals take on cube shapes and absorb heat. When the weather gets cooler, the crystals become cooler and even back to their original tetragonal structure.
M: That's truly unbelievable. You said that it'll be a decade before this type of clothes will be available. What a shame! I don't think I can wait that long.

A．He is surprised.
B．He is skeptical.
C．He is disgusted.
D．He is alarmed.

听力原文：W: Hello？
M: Hello, I'm calling about the apartment that was advertised in the newspaper this morning. Is it still available？
W: There were two, a three-bedroom and a two-bed room. But the larger one has been rented.
M: Oh, that's Ok. I was only interested in the two-bed room. Can you tell me what it's like？
W: Well it is quite big and 'has sun most of the day. It's really good. It also has a kitchen and there's plenty of closet space.
M: Sounds good. The ad said the rent was 525 dollars a month. Does that include heat and water？
W: No, lodgers have to pay themselves.
M: I see, and what about parking？
W: That's no problem at all. Each lodger is assigned a particular space, and that space is theirs as long as they stay in the apartment.
M: Great! Given how rents are these days, this seems to be too good to be true.
W: Listen, why don't you come over tomorrow and see for yourself？ Call me, I'll be in all morning.
M: Fine, see you then.
(20)
A．It's rather expensive.
B．It's too small for the man.
