如何判斷填空題的基本邏輯關係
GRE填空題中常會出現長難句的情況，這個時候想要填對最關鍵的就是根據一些特殊詞彙判斷語言上的邏輯關係，從而理順句子結構。很多時候，填空題的答案就在句子中，關鍵是要根據線索把它找出來。
1.根據關鍵詞彙來判斷語言上的基本邏輯關係
因果、(because, in that, for, therefore, thus, accordingly, consequently, given, hence, so…that, to, if…then, , as long as……)轉折、(albeit, although, though, but, despite, even though, however, in spite of, nevertheless, nonetheless, notwithstanding, while, whatever, regardless, even if, even though, yet, and yet……)遞進、(even, indeed………)對比、(in contrast, on the contrary, far from, on the other hand, rather than, instead of, not…but, paradoxically, ironically, surprisingly, unexpectedly, curiously……)等等。
2.尋找句子中的重複關係
作爲研究生院入學的參考考試，也許是爲了體現內容有深度，很多句子涉及到了各個學科的背景知識。同時基於對所有學科學生都要公平的原則，所有的題目在 解題點上都不涉及背景知識。爲了做到這一點，很多時候ETS都是把答案放到句子中，然後用語言上的線索提示你去把它找出來。以下是提供重複線索的幾種常見 形式：
(1) 簡單的直接重複
The eradication of pollution is not merely a matter of ___, though the majestic beauty of nature is indeed an important consideration.
A. economics B. legislation C. cleanliness D. aesthetics E. restoration
儘管大自然的美確實很重要，但污染的消除不僅是什麼問題，當然不僅是美的問題。
Comparatively few rock musicians are willing to laugh at themselves, although a hint of----can boost sales of video clips very nicely.
A. self-deprecation B. congeniality C. cynicism D. embarrassment E. self-doubt
搖滾樂手很少自嘲，儘管什麼東西能促進錄像短片的銷售，當然就填自嘲。
Melodramas, which presented stark oppositions between innocence and criminality, virtue and corruption, good and evil, were popular precisely because they offered the audience a world ___of___.
A. bereft.. theatricality B. composed.. adversity C. full.. circumstantiality D. deprived.. polarity
E. devoid.. neutrality
Melodramas這個詞不認識也沒關係，既然它表現的是無辜與罪行、道德與墮落、善與惡之間的刻板對立，那麼它提供給觀衆什麼樣的世界呢?當然是刻板對立的世界，只有E選項符合要求。
(2) 解釋型重複
The Muses are___deities: they avenge themselves without mercy on those who weary of their charms.
A. rueful B. ingenuous C. solicitous D. vindictive E. dispassionate
冒號後面的內容就是正確選項D這個詞的釋義，所以不知道繆斯是什麼東西也能輕鬆選對。
Unenlightened authoritarian managers rarely recognize a crucial reason for the low levels of serious conflict among members of democratically run work groups: a modicum of tolerance for dissent often prevents___.
A. demur B. schism C. cooperation D. compliance E. shortsightedness
冒號後面的內容解釋了民主方式運作的工作團體中爲何少有嚴重的衝突，所以即使看不懂a modicum of
tolerance for dissent是什麼東西，也應該知道這個東西避免了嚴重衝突，故選B。
(3) 根據語法結構推斷重複：
The valedictory address, as it has developed in American colleges and universities over the years, has become a very strict form, a literary ___ that permits very little ___.
A. text.. clarity B. work.. tradition C. genre.. deviation
D. oration.. grandiloquence E. achievement.. rigidity
a literary ___ that permits very little ___. 是前面的a very strict form的同位語，所以第一空格填form的同義或近義詞，that permits very little___. 這個從句完成後應爲strict的同義或近義詞。
Many more eighteenth-century novels were written by women than by men, but this dominance has, until very
recently, been regarded merely as ___ fact, a bit of arcane knowledge noted only by bibliographers.
A. a controversial B. a statistical C. an analytical D. an explicit E. an unimpeachable
這道題同樣，a bit of arcane knowledge noted only by bibliographers.是前面的___ fact的同義重複，所以空格應填入文獻學家關注的事實，已知的五個選項裏顯然只有B選項的statistical(統計的)是文獻學家的份內工作。
(4) 憑藉具有指示作用的形容詞或代詞來尋找重複
Longdale and Stern discovered that mitochondria and chloroplasts ___ a long, identifiable sequence of DNA; such a coincidence could be ___ only by the transfer of DNA between the two systems.
A. manufacture.. accomplished B. reveal.. repeated C. exhibit.. determined
D. share.. explained E. maintain.. contradicted
下半句的such a coincidence說明第一空格的動詞填入後應體現爲是一種巧合，兩個看不懂是什麼的、只知道是不一樣的東西(非相關專業的絕大部分學生是不太可能認 識mitochondria和chloroplasts這兩個詞的)怎樣了一個長的、可以認爲是一模一樣的DNA序列就是一個巧合呢?當然只有D的 share表示了這個意思。
Laws do not ensure social order since laws can always be ___ , which makes them ___ unless the authorities have the will and the power to detect and punish wrongdoing.
A. contested.. provisional B. circumvented.. antiquated C. repealed.. vulnerable
D. violated.. ineffective E. modified.. unstable
Which指代逗號前面的那句話，也就是“法律不保障社會秩序”，這就使得法律怎樣呢?當然只有D選項的ineffective符合句意。
