GWD - CR - 大全 附解释(9)

Parkdale C. The ratio of violent to nonviolent crimes committed during the past four years in Meadowbrook and Parkdale D. The violent crime rates in Meadowbrook and Parkdale four years ago

E. How Meadowbrooks‘ expenditures for crime prevention over the past four years compare to Parkdale‘s expenditures.

答案为D无疑。

原文结论的意思实际为：现在M和P哪个犯罪率高。

在得出这个结论时原文提出的证据是和四年前比的数据，即以四年前的犯罪率作为基础，所以要比较现在的犯罪率，必须比较四年前的犯罪率。如果四年前M的犯罪率比P低很多很低，那末虽然这四年M的犯罪率增长达，但现在的犯罪率也会比P低。原文没考虑这种可能性。即D

B的意思为在过去四年里，M和P的人口增长率相比情况。因为犯罪率本身已算进了人口增长，所以不必再考虑人口增长情况。B是无关项。

这种题目好像也是通病，不能仅仅通过增长率来下结论，说增长之后的数量对比，也要考虑到基数的比较。注意这类题目。！！！

T-4-Q21

The OLEX Petroleum Company has recently determined that it could cut its refining costs by closing its Grenville refinery and consolidating all refining at its Tasberg refinery. Closing the Grenville refinery, however, would mean the immediate loss of about 1,200 jobs in the Grenville area. Eventually the lives of more than 10,000 people would be seriously disrupted. Therefore, OLEX‘s decision, announced yesterday, to keep Grenville open shows that at OLEX social concerns sometimes outweigh the desire for higher profits.

Which of the following, if true, most seriously undermines the argument given?

18

A. The Grenville refinery, although it operates at a higher cost than the Tasberg refinery, has nevertheless been

moderately profitable for many years. B. Even though OLEX could consolidate all its refining at the Tasberg plant, doing so at the Grenville plant would not

be feasible. C. The Tasberg refinery is more favorably situated than the Grenville refinery with respect to the major supply routes

for raw petroleum. D. If the Grenville refinery were ever closed and operations at the Tasberg refinery expanded, job openings at Tasberg

would to the extent possible be filled with people formerly employed at Grenville. E. Closure of the Grenville refinery would mean compliance, at enormous cost, with demanding local codes regulating

the cleanup of abandoned industrial sites.

原文说为了cut the cost，决定要去关掉G，然而由于G的关闭会引起很多社会问题。 原文就得出结论，G继续开，是考虑到社会问题

E-关掉后，要清理遗留物的cost非常高，所以继续开，说明G继续开还是考虑到成本而不是社会问题

A-profit的多少，与原文的cost cut无关，原文并没有说 G是不赚钱的，只是说成本太高了，基于降成本的考虑,刚开始决定关掉G B-排除他因，consolidate不行，仍继续开，说明是考虑社会问题； C-排除他因，没有T方便，仍继续开，说明是考虑社会问题 D-无关，问的是G的情况，与T没啥关系啊．

T-4-Q28

In Berinia, the age at which people could begin to drink alcohol legally used to be 18. In 1990, in an attempt to reduce alcohol consumption and thereby to reduce alcohol-related traffic deaths among Berinians under 21, the legal drinking age was raised to 21. Alcohol-related traffic deaths among people under 21 have decreased significantly since 1990. Nevertheless, surveys show that people in that age-group drink just as much alcohol as they did before 1990. Which of the following, if true of Berinia, most help to resolve the apparent discrepancy?

A. For the population as a whole, annual alcohol consumption is no lower now than it was in 1990

B. Alcohol consumption away from home, for example in bars and restaurants, is much lower among people under 21

than it was in 1990 C. The proportion of people under 21 who own a car is higher now than it was in 1990

D. Alcohol consumption is lower among people under 21 than among adults in most other age-groups. E. Alcohol-related traffic deaths among people over 21 have increased slightly since 1990.

原文说，新措施实施后，死的人少了很多。说明新措施是有效的；（这里文中有一个潜在推理或者假设：新措施有效是通过降低了21岁以下人的喝酒量来实现的。）最后一句说实际上21岁以下的人喝的酒并没有减少。---- 与这个潜在推理/假设矛盾。（discrepancy). B说在酒吧和餐馆里喝酒的人少了很多。这里有一个推测和一个假设，推测，新措施后，相当一部分喝酒的人从酒吧和餐馆转移到了家里；假设，在家里喝酒不会受新措施限制。基于原文喝酒的总量没变，推测成立。这个假设算是一个COMMON SENSE,所以选B.

T-4-Q32

Delta products, Inc., has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity. The question has been raised whether it can be concluded that for a given level of output, Delta‘s operation now causes less fossil fuel to be consumed than it did formerly. The answer, clearly, is yes, since the amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount needed to power the older technologies, provided that the level of output is held constant. In the argument given, the two boldface portions play which of the following roles?

A. The first identifies the context of the conclusion of the argument; the second provides support for that conclusion. B. The first provides support for the conclusion of the argument; the second identifies the content of that conclusion. C. The first states the position that the argument opposes; the second states the conclusion of the argument. D. Each provides evidence that calls the conclusion of the argument into question. E. Each provides support for conclusion of the argument. T-4-Q34

In Kravonia, the average salary for jobs requiring a college degree has always been higher than the average salary for jobs that do not require a degree. Current enrollments in Kravonia‘s colleges indicate that over the next four years the

percentage of the Kravonian workforce with college degree will increase dramatically. Therefore, the …… 此处隐藏：5417字，全部文档内容请下载后查看。喜欢就下载吧 ……
