问题  
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、Lowering transportation fees.
B、The environmental engineering class.
C、The man’s car in the shop.
D、Better environment.
答案D
解析 对话中女士有车不开，宁愿挤公交车；上环境工程课；对节能环保绝热器感兴趣，均表明她关注环境，有浓厚的环保意识。因此，D正确。实际上本题是问对话主题，选项D概括性最强，是答案。其余选项均是细节，或与对话无关。
