新GRE閱讀的文字內(nèi)容復(fù)雜程度有所降低，邏輯復(fù)雜程度持續(xù)增加。而ETS在多年的跟蹤研究后也意識到，恰當(dāng)準(zhǔn)確把握文章內(nèi)部的復(fù)雜邏輯的能力，同研究生階段的成績關(guān)系更大些。下面，我們以一篇樣題為例看一下ETS是如何考查新GRE閱讀文章內(nèi)部的復(fù)雜邏輯：

Policymakers must confront the dilemma that fossil fuels continue to be an indispensable source of energy even though burning them produces atmospheric accumulations of carbon dioxide that increase the likelihood of potentially disastrous global climate change. Currently, technology that would capture carbon dioxide emitted by power plants and sequester 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 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 of other costs associated with electricity delivery.

It is not fully recovered by the prices charged directly to electricity consumers.

對上文的邏輯進(jìn)行提煉我們發(fā)現(xiàn)，得出這樣一個邏輯推理鏈條：

環(huán)保技術(shù)(technology that would capture carbon dioxide emitted by power plants and sequester it harmlessly underground or undersea instead of releasing it into the atmosphere)增加一倍發(fā)電成本(double the cost of generating electricity)。環(huán)保技術(shù)不改變傳輸成本(the cost of electricity transmission and distribution)。最終價格(delivered prices)增加不超過50%。

最終價格=發(fā)電成本+傳輸成本使用環(huán)保技術(shù)后，發(fā)電成本增加了原來的一倍，但是最終價格增長不超過50%，可以得出結(jié)論，發(fā)電成本，最多占最終價格的50%。
