试题详情

题目:

Nitrogen dioxide is a pollutant emitted by automobiles.  Catalytic converters, devices designed to reduce nitrogen dioxide emissions, have been required in all new cars in Donia since 1993, and as a result, nitrogen dioxide emissions have been significantly reduced throughout most of the country.  Yet although the proportion of new cars in Donia's capital city has always been comparatively high, nitrogen dioxide emissions there have showed only an insignificant decline since 1993.
 
Which of the following, if true, most helps to explain the insignificant decline in nitrogen dioxide emissions in Donia's capital city?

选项:

A、More of the cars in Donia's capital city were made before 1993 than after 1993.
B、The number of new cars sold per year in Donia has declined slightly since 1993.
C、Pollutants other than nitrogen dioxide that are emitted by automobiles have also been significantly reduced in Donia since 1993.
D、Many Donians who own cars made before 1993 have had catalytic converters installed in their cars.
E、Most car trips in Donia's capital city are too short for the catalytic converter to reach its effective working temperature.

答案:

E

提问:

这题答案有问题吧?请老师仔细看下,乍一看是选E,但是仔细读原文说的不是污染物一直没有明显降低,而是只有一次降低,E并不能解释只有一次降低。但是D可以,既然大多数人一次性把自己的旧车装了这个转换器,那么就只有一次污染物明显降低,以后就算都换了新车,也不会再有明显降低。

提问:

在DE之间纠结,原文说的是新车上装了一个什么装置,可以减少污染,新车的比例增加了,但是污染下降得不明显。D说旧车也装了这个装置,说明新旧没什么区别,所以污染下降得也不明显。

提问:

a说之前造的比之后的多觉得是有关的留下来 e说的是没达到工作温度有关留下来,然后不会选了,蒙了e但是为啥不是a

提问:

原文我读成:93之后车装了cc,污染物氮应该减少,但是主要城市,虽然有高比例的新车但是污染没减。问解释原因 选项A说在93之前比93之后造的车更多。我错选了A,当时认为A就是顺着原文说的呀 没弄清,讲讲,谢谢
