下面,我們以一篇樣題為例看一下ETS是如何考察文章內(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)文字的邏輯進(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)電成本增加了原來的一倍,但是最終價(jià)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(jià)格的50%。以上文字同傳統(tǒng)GRE考試文章比起來,語言難度不大。難度來自于邏輯復(fù)雜,尤其是在有較大的時(shí)間壓力的情況下,能夠快速清晰的得出結(jié)論,并不容易。
針對(duì)準(zhǔn)備新GRE的國內(nèi)大學(xué)生,在邏輯思維方面訓(xùn)練不多,新GRE的考試正好考到了學(xué)生的弱點(diǎn)。如果準(zhǔn)備新GRE考試,建議加強(qiáng)兩方面訓(xùn)練。
1.英文閱讀過程中,快速歸納邏輯鏈條的能力。很多學(xué)生閱讀仍然停留在翻譯的階段,這在新GRE中會(huì)帶來很大麻煩。
2.增強(qiáng)邏輯思維訓(xùn)練,GRE本質(zhì)來講,是對(duì)英語為母語者的能力考試??疾爝壿嬎季S的敏捷程度,嚴(yán)謹(jǐn)程度,是這個(gè)考試的本質(zhì)。
新GRE閱讀考試主要考察的是考生的邏輯推斷能力,平日練習(xí)時(shí)考生們要加強(qiáng)快速歸納邏輯鏈條的能力和邏輯思維訓(xùn)練,這樣才能備考好新GRE閱讀考試。希望以上這些資料能給備考新GRE的考生有所幫助。
