GRE閱讀理解的三種題型透徹分析

新GRE考試閱讀理解部分有三種題型:
  Multiple-choice Questions — Select One Answer Choice:These are the traditional multiple-choice questions with five answer choices of which the examinee must select one.
  第一種:多項選擇題I (5選1)
  Multiple-choice Questions — Select One or More Answer Choices:These provide three answer choices and ask the examinee to select all that are correct; one, two or all three of the answer choices may be correct. To gain credit for these questions, the examinee must select all the correct answers, and only those; there is no credit for partially correct answers.
  第二種:多項選擇題II(新題型)(在3個選擇項中選擇任意符合題意的答案,1項到3項均可,錯選漏選不給分)
  Select-in-Passage:The question asks the examinee to click on the sentence in the passage that meets a certain description. To answer the question, the examinee chooses one of the sentences and clicks on it; clicking anywhere on a sentence will highlight it.
  第三種:段中點選題(新題型)
  下面,我們以ETS官方樣題來做以分析。
  Sample questions 1 to 3 below are based on this passage:
  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.
  第一種題型:多項選擇題I
  Sample Multiple-choice Questions — Select One Answer Choice
  1. The passage implies which of the following about the current cost of generating electricity?
  A. It is higher than it would be if better technologies for capturing carbon dioxide were available.
  B. It is somewhat less than the cost of electricity transmission and distribution.
  C. It constitutes at most half of the delivered price of electricity.
  D. It is dwelt on by policymakers to the exclusion of other costs associated with electricity delivery.
  E. It is not fully recovered by the prices charged directly to electricity consumers.
  Answer: C
  解析:首先,我們需要找到題干文句中的定位關鍵詞 “the current cost of generating electricity”。之后,將這個關鍵詞定位到文章中去,發現這組定位詞出現在文章當中的第二句話當中:“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.”我們發現文章的下一句話當中出現了這樣的比例關系。“But because sequestration does not affect the cost of electricity transmission and distribution, delivered prices will rise less, by no more than 50 percent.”這說明“sequestration”所導致的發電成本所占的比重不超過包括傳輸在內的總費用(delivered prices)的二分之一。既然只有“發電”和“送電”兩個過程。那么,發電的花費當然是最多只能占到二分之一了。答案C所說正是:“It constitutes at most half of the delivered price of electricity.”故選。通過這道題目,我們發現ETS在新GRE考試中沿用了傳統GRE考試的解題套路。
  第二種題型:多項選擇題II
  Sample Multiple-choice Questions — Select One or More Answer Choices
  Consider each of the three choices separately and select all that apply.
  2. The passage suggests that extensive use of sequestration would, over time, have which of the following consequences?
  A. The burning of fossil fuels would eventually cease to produce atmospheric accumulations of carbon dioxide.
  B. The proportion of the delivered price of electricity due to generation would rise and then decline.
  C. Power plants would consume progressively lower quantities of fossil fuels.
  Answer: B
  解析:首先,從文章中可以看出,沒有什么方法可以“停止”大氣中二氧化碳的累積,所以A選項中所提到的“The burning of fossil fuels would eventually cease to produce atmospheric accumulations of carbon dioxide.”顯然是錯誤的。另外,整個文章中也并沒有提供一種方法可以使得電廠可以 “減少化石燃料的使用量”,所以C選項顯然不符合題意。由于文章中的最后二句話中指出:“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.”所以,隨著化石燃料使用量的增加,未來可以預期的發電成本將會先增加后減少。應該選擇選項B(The proportion of the delivered price of electricity due to generation would rise and then decline.)由此可以看出,盡管新GRE考試中出現了新的多項選擇題型,但是并沒有在實質上改變原有的命題核心思想。即考察考生的對文章事實的理解和推斷進一步信息的能力。所以,原有的解題方法的運用不僅是可能的,也是必要的應對新GRE考試的工具。
  第三種題型:段中點選題
  Sample Select-in-Passage Question
  3. Select the sentence that explains why an outcome of sequestration that might have been expected would not occur.
  Answer:
  “But because sequestration does not affect the cost of electricity transmission and distribution, delivered prices will rise less, by no more than 50 percent.”
  面對這三種全新的題型,考生該具備哪些能力又該如何準備呢?
  除卻傳統GRE復習過程中對于語篇結構和句法的把握之外,段中點選題(Select-in-Passage Question)又為我們提出了新的要求。這種題型要求我們準確把握文章中各個句子之間的邏輯關系。由于傳統GRE閱讀理解考試當中很少涉及此類信息的考察,句際關系就成了多數考生思維上的盲點。
  事實上,英文作為一種“形合”的語言,它的起承轉合之間經常依賴邏輯關系詞的介入和輔助。以第三題為例,此題表面上是考察考生對句子的理解和信息搜索能力,而實際上則是考察問題中所涉及的結論在原文當中是如何被解釋的。如果各位能夠注意到題干當中的“…explains why an outcome of sequestration…”,那么,就可以迅速而直接地定位到原文的表示原因的句式(…But because sequestration…)當中。這種why和because之間的微妙對應關系可以泛化到廣闊的同類命題當中去。
