2018年12月CET6聽力模擬試題

　　M: Hi, Diana. I'm surprised to see you on the citybus. Your car in the shop?

　　W: No. [19]I've just been thinking a lot about theenvironment lately. So I decided the air will be a lotcleaner if we all use public transport when we could.

　　M: I'm sure you are right. The diesel bus isn't exactlypollution free.

　　W: True. They'll be running a lot cleaner soon. [20]We were just talking about that in myenvironmental 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 fuelefficiency. 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. [21]What it does is reflect back the heat of burning fuel. So the fuel will burn muchhotter 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.

　　Questions 1 to 4 are based on the conversation you have just heard.

　　1.

　　A. She is environmentaly-concerned.

　　B. She wants to save money.

　　C. Her car is being repaired in the shop.

　　D. She wants to see the man on the bus.

　　2.

　　A. Diana believes the air is not likely to be cleaner.

　　B. Diana thinks the diesel(柴油機(jī)) 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(絕熱器).

　　3.

　　A. It makes the fuel burn more efficiently.

　　B. It helps release more unburned fuel.

　　C. It is easy to install.

　　D. It is very cheap.

　　4.

　　A. Lowering transportation fees.

　　B. The environmental engineering class.

　　C. The man's car in the shop.

　　D. Better environment.

　　參考答案及解析

　　1. Why does Diana take a bus that day?

　　正確答案：A

　　解析：男士問(wèn)Diana為什么乘坐公共汽車，是不是她的汽車在維修。女士回答說(shuō)不是，她乘坐公共汽車是因?yàn)樽罱�她在考慮環(huán)境問(wèn)題。大家都使用公共交通的話，空氣會(huì)干凈一些。可見她關(guān)注環(huán)境，故A正確。B未提及，C、D內(nèi)容與對(duì)話不符。

　　2. What is true about Diana?

　　正確答案：C

　　解析：女士說(shuō)到：“在環(huán)境工程課上我們剛剛談到過(guò)這一點(diǎn)�！笨梢娝�修了一門環(huán)境工程課，故C正確。四個(gè)選項(xiàng)都以Diana為主語(yǔ)，本題定然問(wèn)她的情況。要根據(jù)選項(xiàng)關(guān)鍵詞聽對(duì)話，把涉及關(guān)鍵詞的信息與選項(xiàng)對(duì)照，判斷選項(xiàng)正誤。

　　3. What justifies the installation of a new insulator in the buses according to Diana?

　　正確答案：A

　　解析：對(duì)于安裝新的絕熱器，女士說(shuō)：“它的作用在于它可以把燃料燃燒的熱量反射回來(lái)，這樣燃料燃燒時(shí)的溫度就會(huì)更高，燃燒也就更徹底�！笨梢娊^熱器可以提高燃燒率，A正確。鑒于我們并不知道it指什么，聽錄音時(shí)，必須對(duì)有關(guān)事物予以重視。對(duì)話中，男士重復(fù)反問(wèn)了一個(gè)詞“An insulator?”表明它是對(duì)話中討論的一個(gè)重點(diǎn)，問(wèn)題it可能與它有關(guān)。緊接著女士的回答又用了“What it does is...”的強(qiáng)調(diào)結(jié)構(gòu)，并用“So...”說(shuō)明結(jié)果，相關(guān)內(nèi)容即構(gòu)成本題答案。

　　4. What is the major concern of the woman?

　　正確答案：D

　　解析：對(duì)話中女士有車不開，寧愿擠公交車;上環(huán)境工程課;對(duì)節(jié)能環(huán)保絕熱器感興趣，均表明她關(guān)注環(huán)境，有濃厚的環(huán)保意識(shí)。因此，D正確。實(shí)際上本題是問(wèn)對(duì)話主題，選項(xiàng)D概括性最強(qiáng)，是答案。其余選項(xiàng)均是細(xì)節(jié)，或與對(duì)話無(wú)關(guān)。
