ETS是如何考查GRE阅读文章的复杂逻辑
英语课
新GRE阅读文章内容复杂程度降低了，但是新GRE阅读变化在于逻辑复杂程度升高。考生们想要获得新GRE阅读理解的高分，则更加注重文章的内在联系。这反映了ETS对于影响研究生阶段学术成功的基本能力的更为深入的把握。
新GRE阅读的文字内容复杂程度有所降低，逻辑复杂程度持续增加。而ETS在多年的跟踪研究后也意识到，恰当准确把握文章内部的复杂逻辑的能力，同研究生阶段的成绩关系更大些。下面，我们以一篇样题为例看一下ETS是如何考查新GRE阅读文章内部的复杂逻辑：
Policymakers must confront the dilemma 1 that fossil fuels continue to be an indispensable source of energy even though burning them produces atmospheric 2 accumulations of carbon dioxide that increase the likelihood of potentially disastrous 3 global climate change. Currently, technology that would capture carbon dioxide emitted by power plants and sequester 4 it harmlessly underground or undersea instead of releasing it into the atmosphere might double the cost of generating electricity. But because sequestration does not affect the cost of electricity transmission and distribution, delivered prices will rise less, by no more than 50 percent. Research into better technologies for capturing carbon dioxide will undoubtedly 5 lead to lowered costs.
1. The passage implies which of the following about the current cost of generating electricity?
It is higher than it would be if better technologies for capturing carbon dioxide were available.
It is somewhat less than the cost of electricity transmission and distribution.
It constitutes at most half of the delivered price of electricity.
It is dwelt on by policymakers to the exclusion 6 of other costs associated with electricity delivery.
It is not fully 7 recovered by the prices charged directly to electricity consumers.
对上文的逻辑进行提炼我们发现，得出这样一个逻辑推理链条：
环保技术(technology that would capture carbon dioxide emitted by power plants and sequester it harmlessly underground or undersea instead of releasing it into the atmosphere)增加一倍发电成本(double the cost of generating electricity)。环保技术不改变传输成本(the cost of electricity transmission and distribution)。最终价格(delivered prices)增加不超过50%。
最终价格=发电成本+传输成本使用环保技术后，发电成本增加了原来的一倍，但是最终价格增长不超过50%，可以得出结论，发电成本，最多占最终价格的50%。
