GRE閱讀：從情境模擬到技能考核.

　　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。這反映了ETS對(duì)于影響研究生階段學(xué)術(shù)成功的基本能力的更為深入的把握。而ETS在多年的跟蹤研究后也意識(shí)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(jī)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(duì)上文的邏輯進(jìn)行提煉我們發(fā)現(xiàn)，得出這樣一個(gè)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(jià)格(delivered prices)增加不超過(guò)50%。

　　最終價(jià)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(lái)的一倍，但是最終價(jià)格增長(zhǎng)不超過(guò)50%，可以得出結(jié)論，發(fā)電成本，最多占最終價(jià)格的50%。

　　新GRE閱讀篇幅縮短，數(shù)量增加，題型更加多樣化，各位考生在新GRE閱讀理解訓(xùn)練時(shí)應(yīng)多加總結(jié)積累經(jīng)驗(yàn)，不要盲目追求數(shù)量，提高新GRE閱讀能力不是一日之功，要打好“持久戰(zhàn)”。
