问题
M: Hi, Diana. 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 transport when we could.
M: I’m sure you are right. The diesel bus isn’t exactly pollution free.
W: True. They’ll be running a lot cleaner soon.[10]We were just talking about that in my environmental engineering class.
M: What could the city do? Install pollution filters in all their buses?
W: They could, but those filters make the engines work harder and really cut down on the fuel efficiency. Instead, they found a way to make their engines more efficient.
M: How?
W: Well, there is a new insulator. And you spray a thick coat of it on the engine.
M: An insulator?
W: Yeah. What it does is 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 the air.
W: And the bus will need less fuel. So with the saving on fuel cost, they say this will all pay for itself in just six months.
9. Why does Diana take a bus that day?
10. What do we learn about Diana?
11. What justifies the installation of a new insulator in the buses according to Diana?
12. What is the major concern of the woman?
选项
A、It makes the fuel bum more efficiently.
B、It helps release more unburned fuel.
C、It is easy to install.
D、It is very cheap.
答案
A
解析
对于安装新的绝热器,女士说:“它的作用在于它可以把燃料燃烧的热量反射回来,这样燃料燃烧时的温度就会更高,燃烧也就更彻底。”可见绝热器可以提高燃烧率,A正确。鉴于我们并不知道it指什么,听录音时,必须对有关事物予以重视。对话中,男士重复反问了一个词“An insulator?”表明它是对话中讨论的一个重点,问题it可能与它有关。紧接着女士的回答又用了“What it does is…”的强调结构,并用“So...”说明结果,相关内容即构成本题答案。
