标题: OG verbal CR第10题 [打印本页] 作者: yibiaobiao 时间: 2011-10-7 05:06 标题: OG verbal CR第10题 At a recent conference on environmental threats to the North Sea, most participating countries favored uniform controls on the quality of effluents, whether or not specific environmental damage could be attributed to a particular source of effluent. What must, of course, be shown, in order to avoid excessively restrictive controls, is that_________________. A) any uniform controls that are adopted are likely to be implemented without delay. B) any substance to be made subject to controls can actually cause environmental damage. C) the countries favoring uniform controls are those generating the largest quantities of effluents. D) all of any given pollutant that is to be controlled actually reaches the North Sea at present. E) environmental damage already inflicted on the North Sea is reversible. 为什么不选d呢？材料开始就表明是on threats to the North Sea。 觉得B答案的问题在：it is unnecessary to control the substance which doesnot reach the north sea even though it can cause environmental damage作者: sdcar2010 时间: 2011-10-7 08:39
D) is not necessary because some toxic material might not reach North Sea at present, but will do in the future. So D) is too limited and too RESTRICTIVE.
B), on the other hand, is NECESSARY and not too RESTRICTIVE since for any substance to make the list, it has to cause environmental damage in one way or another.作者: dennis2k 时间: 2014-1-31 02:41
我的理解，不知道是否正确，忘NN审核！
论点：不能控制过度
论据：某种污水->环境问题->统一控制污水
漏洞：有的污水未必是导致环境问题的罪魁祸首，统一控制可能会导致这部分无辜的污水也一起控制了，属于控制过度。故应在控制的时候注意所控制的污水确实是罪魁祸首。
