OG 48-284

(The following is based on material written in 1996.)

The Montreal Protocol on Substances that Deplete the Ozone Layer, signed in 1987 by more than

150 nations, has attained its short-term goals: it has decreased the rate of increase in amounts of

most ozone-depleting chemicals reaching the atmosphere and has even reduced the atmospheric

levels of some of them. The projection that the ozone layer will substantially recover from ozone

depletion by 2050 is based on the assumption that the protocol’s regulations will be strictly

followed. Yet there is considerable evidence of violations, particularly in the form of the release of

ozone-depleting chlorofluorocarbons (CFC’s), which are commonly used in the refrigeration,

heating, and air conditioning industries. These violation reflect industry attitudes; for example, in

the United States, 48 percents of respondents in a recent survey of subscribers to Air Conditioning,

Heating, and Refrigeration News, and industry trade journal, said that they did not believe that

CFC’s damage the ozone layer. Moreover, some in the industry apparently do not want to pay for

CFC substitutes, which can run five times the cost of CFC’s. Consequently, a black market in

imported illicit CFC’s has grown. Estimates of the contraband CFC trade range from 10,000 to

22,000 tons a year, with most of the CFC’s originating in India and China, whose agreements

under the Protocol still allow them to produce CFC’s. In fact, the United States Customs Service

reports that CFC-12 is a contraband problem second only to illicit drugs.

284. The author of the passage compares the smuggling of CFC’s to the illicit drug trade most

likely for which of the following reasons?

(A)    To qualify a previous claim

(B)    To emphasize the extent of a problem

(C)    To provide an explanation for an earlier assertion

(D)    To suggest that the illicit CFC trade, likely the illicit drug trade, will continue to increase  

(E)    To suggest that the consequences of a relatively little-knows problem are as serious as those of a well-known one

答案B，，，，请教为什么E不行啊？我觉得主要是要强调严重程度，菜鸟，请轻拍，谢谢啦！

自己踢一脚，，，，，，，，，，，，

lukeleng

the smuggling of CFC’s 和 the illicit drug trade 都来源于the United States Customs Service的报告，就不能是E吧？

恩，先谢谢楼上的

但是个人觉得即使是从同一个报告里出来的也有广为人知的和大家都不知道的数据。

little-knows problem 和well-known one感觉说明的是问题的知晓度，并不是大家只能从这个报告里面知道。

比如，一个报告里面包含：中国人口总数量（大家都知道），中国某市在地震时捐款（大家本来不知道）

而且之前也出现了有些人 said that they did not believe that CFC’s damage the ozone layer，个人感觉可以说明这个事情的群众认知度不高。

不知道大家还有何见解哈？

谢谢了！
