标题: [求助] 大全TEST B NO. 2 [打印本页] 作者: leoxiaoming 时间: 2009-12-4 10:12 标题: [求助] 大全TEST B NO. 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. (E) The increased sightings of bird species in and around London reflect an actual increase in the number of species in the area.
正确答案: A
偶觉得A是不对，但是同时B也有问题。我已经看了论坛内关于这道题的讨论，还是觉得B有问题，理由如下：
题目推论是 因为"Air-pollution regulation on local industry" 导致 "鸟多"，所以"需要在其他城市推广" B是说 "Air-pollution regualtion on local industry" 会SIGNIFICANTLY影响空气质量。 1. 空气质量和鸟多不一定相关啊！ 2.那Air-pollution regulation即使不会SIGNIFICANTLY影响空气质量，只要能影响到鸟类数量增多的程度，就应该在其他城市推广啊。 所以偶觉得B与题目也无关。
