W: Hi, Mike.
M: Hi. I’m surprised to see you on the city bus. Why not drive your car?
W: (23)I’ve been thinking about the environment lately. If we all use public transportation when we could, the air will be much cleaner.
M: Right. But the 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 going to 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, (24)there is a material called the coniine oxide. It’s a really good insulator. And a thick coat of it gets sprayed on the certain part of the engine.
M: An insulator?
W: Yes. (25)It reflects 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 the 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 this stuff to spray their car engines.
W: Well, not really that easy. To melt the materials before you can spray a coat of it on the engine parts, you first have to heat it over 10,000 degrees. It’s not something we are able to do ourselves.
选项
A、People can spray coniine oxide on their car engines easily.
B、The material works as a pollution filter.
C、The material saves fuel for it reflects back the heat of burning fuel.
D、When burnt, the material will save fuel.
答案
C
解析
从女士的解释可知这种材料为 coniine oxide且不容易融化,一般人无法自行操作,故A项被排除。而且Coniine oxide反射燃料的热量,由此可知,这种材料可省燃料,故选C项。
