What’s the conversation mainly about?
W: Hi, Bill. You weren’t in engineering class today, were you?
M: Hi, Amy. I have the flu. I was wondering if you could tell me what went on.
W: Actually we had an interesting class. Dr. Collin talked about a new type of fuel.
M: Oh, yeah?
W: Uh-hum. It’s called dimethyl ether or DME.
M: Oh, I remember reading something about DME. It’s mostly used in spray cans, right?
W: Right. DME doesn’t destroy the ozone, so it’s been environmentally friendly.
M: But doesn’t DME pollute the air if it’s burned in an engine?
W: Dr. Collin said something about its exhausts being clear, that it doesn’t release as many pollutants as diesel fuel. And he mentioned something about DME being more efficient than other alternative fuels.
M: So when will it replace diesel fuel?
W: Not for a while. It’s not economical to mass-produce.
M: Well, thanks for the information. I guess I won’t need to borrow your notes.
W: Well, maybe you should look at them. We are having a test next week.
M: Okay, could you give them to Mike Andrews? I think he is in your psychology class. He is my roommate.
W: Sure. I hope you’re feeling better soon.
M: Thank you.
选项
A、A more economical diesel fuel.
B、Characteristics of a new type of fuels.
C、Where a new energy source is located.
D、How to develop alternative energy sources.
答案
B
解析
主旨大意题。男士因为患流感,没有上工程课。女士告诉他上课内容。通过女士的介绍:DME不会破坏臭氧层,更环保,燃烧后排放的气体是清洁的,但大量生产的造价较高。可以判断出谈话者谈论的是一种新型燃料的特点,即B项。
