标题: 大全testB-2

2.     In the years since the city of London imposed strict air-pollution regulations on local industry, the number of bird species seen in and around London has increased dramatically. Similar air-pollution rules should be imposed in other major cities.


Each of the following is an assumption made in the argument above EXCEPT:


(A) In most major cities, air-pollution problems are caused almost entirely by local industry.


(B) Air-pollution regulations on industry have a significant impact on the quality of the air.


(C) The air-pollution problems of other major cities are basically similar to those once suffered by London.


(D) An increase in the number of bird species in and around a city is desirable.A


(E) The increased sightings of bird species in and around London reflect an actual increase in the number of species in the area.



why choose A?  I choose D.


Thanks for replying.

我是这么理解的:


except 表明:如果选项不……,结论也能成立


A 大多数城市里,空气污染问题几乎完全是由当地工业造成的


如果不是完全由工业造成,其他一些问题也会造成污染,但只要工业会污染空气,就需要有执行相关政策,这样至少可以增加一点鸟的数量。


D 希望在城市里或城市周围增加鸟的数量。


如果不希望增加鸟的数量,那也不需要采取相关政策控制空气污染了。结论就不成立了。


不知讲的对不对,共同探讨

本推理的结论是Similar air-pollution rules should be imposed in other major cities, 其依据是London imposed stritct air-pollution regulations on local industry从而导致London周围的鸟类(可见的)数量增加。推理方法用到了类比,london 和其他城市,以及imposed stritct air-pollution regulations on local industry和鸟类(可见的)数量增加的因果关系,但没有涉及其它城市的污染的原因是almost entirely by local industry or not.

所以A和本题无关

我开始也选A,选A是加入了很多自己的主观想象。

好象很多人问这题啊    在太傻上也看到过这个题目。

法令-->鸟多-->法令需要推广。
同意选A,因为就算不是almost entirely,但至少也有点关系。
不选D的原因是如果这个现象不被大众接受(即见到鸟的种类多了),那这套法令就不用被推广了。
希望大家指正。
