四級(jí)標(biāo)準(zhǔn)聽力測(cè)試模擬五Section A答案解析(4)

字號(hào):

W: So there’s little actual wastage?
    M: But that doesn’t eliminate cost. The reprocessing isn’t done for nothing.
    W: But electricity from a nuclear-powered station is cheaper than from a coal-fired plant, isn’t it?
    M: Well, the cost of operation of nuclear stations is only half the cost of even the leastexpensive coal-fired stations. And later on the figures will show an even greater advantage for nuclear energy.
    W: But don’t nuclear stations cost more to build?
    M: Yes, they do. However, their cheaper running gains more than offsets the construction costs.
    W: And aren’t the nuclear stations cleaner in operation?
    M: Yes, and they’re better looking than conventional stations and can be built in places unsuitable for conventional plants. In most cases, they are safe.
    Questions 22 to 25 are based on the conversation you have just heard.
    22. What are the two speakers talking about?
    【解析】選[D]。聽對(duì)話,首句問(wèn)使用核能發(fā)電的優(yōu)點(diǎn),后面則從運(yùn)營(yíng)成本、清潔度以及安全性方面談到了核能發(fā)電站的優(yōu)點(diǎn)。聽問(wèn)題,問(wèn)談?wù)摰脑掝},概括起來(lái)就是[D]。
    23. How many tons of coal can produce the same electricity as it can be produced by one ton of enriched uranium fuel?
    【解析】選[B]。聽音時(shí)注意數(shù)據(jù)信息,as from 75,000 tons of coal,做筆記。聽問(wèn)題,問(wèn)多少噸煤和一噸鈾產(chǎn)生的電量相當(dāng),[B]為細(xì)節(jié)再現(xiàn)。
    24. Where is the used fuel disposed of?
    【解析】選[D]。聽音時(shí)注意提到的能源機(jī)構(gòu)名稱,dispatched to the United Kingdom Atomic Energy Authority,做筆記。聽問(wèn)題,問(wèn)使用后的燃料放到哪里去?[D]為細(xì)節(jié)再現(xiàn)。
    25. Which is not the advantage of the nuclear stations?
    【解析】選[B]。聽音時(shí)注意核能發(fā)電站和煤發(fā)電站的對(duì)比,[A]、[C]、[D]都是核能發(fā)電站的優(yōu)點(diǎn),問(wèn)到nuclear stations cost more to build,回答是Yes。而題干問(wèn)的是核能發(fā)電站的缺點(diǎn),由此可知[B]正確。
