M: Hi, Diana. I’m surprised to see you on the city bus. Your car in the shop?
W: No. [8]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. [9]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. [10]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.
8. Why does Diana take a bus that day?
9. What is true about Diana?
10. What justifies the installation of a new insulator in the buses according to Diana?
11. What is the major concern of the woman?
选项
A、Diana believes the air is not likely to be cleaner.
B、Diana thinks the diesel (柴油机) bus is free of pollution now.
C、Diana has taken a class on environmental engineering.
D、Diana sounds pessimistic about the future of the insulator (绝热器).
答案
C
解析
女士说到:“在环境工程课上我们刚刚谈到过这一点。”可见她修了一门环境工程课,故C正确。四个选项都以Diana为主语,本题定然问她的情况。要根据选项关键词听对话,把涉及关键词的信息与选项对照,判断选项正误。
