鍛煉邏輯思維提升GRE閱讀能力

　　通過對舊GRE考題和兩次改革后的樣題比較，我們可以很清楚的發(fā)現(xiàn)，新GRE閱讀的文字內(nèi)容，復雜程度有所降低。而邏輯復雜程度持續(xù)增加。這反映了ETS對于影響研究生階段學術成功的基本能力的更為深入的把握。實際上GRE考試閱讀文章難度，略高于北美研究生所需閱讀文章難度，采用這種形式的文章，主要目的是模擬較高難度下研究生閱讀的情景，以期能夠測出學生的潛力，這個思路有點類似于我們常說的壓力面試。

　　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.

　　對黑色部分文字的邏輯進行提煉我們發(fā)現(xiàn)，得出這樣一個邏輯推理鏈條。

　　環(huán)保技術(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%，可以得出結論，發(fā)電成本，最多占最終價格的50%。

　　以上文字同傳統(tǒng)GRE考試文章比起來，語言難度不大。難度來自于邏輯復雜，尤其是在有較大的時間壓力的情況下，能夠快速清晰的得出結論，并不容易。

　　針對新GRE的準備思路國內(nèi)大學生，在邏輯思維方面訓練不多，新GRE的.考試正好考到了學生的弱點。如果準備新GRE考試，建議加強兩方面訓練。

　　1、 英文閱讀過程中，快速歸納邏輯鏈條的能力。很多學生閱讀仍然停留在翻譯的階段，這在新GRE中會帶來很大的麻煩。

　　2、 增強邏輯思維訓練，GRE本質來講，是對英語為母語者的能力考試�？疾爝壿嬎季S的敏捷程度，嚴謹程度，是這個考試的本質。
