附上原篇和OG解释。我错选了E。我理解OG的解释，但是不太明白E的错误所在。是不是OG比较直线思维，而E太延伸了？

Passage 48

(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
            (B)

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

284.

This question asks you to identify the purpose of the author’s comparison of CFC smuggling and

the illicit drug trade. The best answer is B. The author notes that the smuggling of CFC’s is, in the

view of the United States Customs Service, a problem “second only” to the illicit drug trade. This

provides a point of reference that emphasizes the extent of the CFC smuggling problem. Choice A

is not correct To qualify a claim is to weaken or soften it. The author’s comparison of CFC

smuggling to the illicit drug trade in fact underscores the previous claim, which ahs to do with the

amount of contraband CFC’s traded each year on the black market. Choice C is not correct

because the comparison of CFC smuggling to the illicit drug trade does not provide an explanation

for an assertion made in the passage. Choices D and E are not correct because the comparison of

CFC smuggling to the illicit drug trade illustrates the extent of the CFC smuggling problem, but

does not suggest further similarities between the two phenomena, such as the likelihood of their

increase. The author also does not express any opinion as to the relative seriousness of the two

problems’ consequence.

E不对，《关于消耗臭氧层物质的蒙特利尔议定书》是一百五十多个国家签字的，不是little-knows problem

second only to 典型的强调语气．是程度的比较．不是定量所以A)   To qualify a previous claim不对

我不同意啊，我觉得很少人知道氟利昂走私是这么严重的，严重到了仅次于非法药品。

In fact, the United States Customs Service reports

the United States Customs Service 的报告说，该不是well-known,也不是少有人知．

呵呵，我有点悟到问题是出在consequences这个词上了~
