提高GRE填空正確率的不二途徑，一是有良好的單詞基礎，而容易被忽略的第二個條件，則是對題目進行邏輯分析。一道填空題，如果選對了，卻不能有條理地把分析思路表達出來，或明確指出做題的線索，則還沒有掌握做填空題的真諦。
接下來我會在每次的真題考試中，挑選出有挑戰性的難題，或容易做錯的題目，為大家附上深度解析，希望能夠幫助備考的同學們在考場上思路更加清晰，穩拿填空滿分。
1. 57-5
Parker’s model of human affairs reflects (i)_____ outlook, in stark contrast to the generally (ii)_____ premises that her colleagues in the economics department adopt in their work. Accordingly, her conclusions (iii)_____ theirs.
- 解析：
Parker’s model of human affairs reflects (i)_____ outlook, in stark contrast to the generally (ii)_____ premises that her colleagues in the economics department adopt in their work. Accordingly, her conclusions (iii)_____ theirs.
－做題關鍵信息: i空和ii空聯動，根據in stark contrast to對比關鍵詞確定兩空互為取反。iii空根據accordingly因果關係詞取同推知，與前文句意 － 即Parker的研究和她同事的研究大相逕庭 － 等價。
－答案：ADI
－單詞：
premise n. 前提
sanguine adj. 樂觀的
introspective adj. 反省的，內省的
technical adj. 技術的，工藝的
pessimistic adj. 悲觀的
theoretical adj. 理論的，假設的
distinctive adj. 獨特的，與眾不同的
diverge v. 存在分歧，相悖，偏離
－翻譯：
Parker的人際關係的模型體現出樂觀的前景，這與她經濟學院其他同事論文中所採用的悲觀前提大相逕庭。所以，Parker得出的結論和他們的也完全相悖。
2. 70-4
The report is admittedly (i)_____ : it is intended to suggest new lines of research rather than to deal with the subject in a (ii)_____ manner.
- 解析：
The report is admittedly (i)_____ : it is intended to suggest new lines of researchrather than to deal with the subject in a (ii)_____ manner.
－做題關鍵信息：i空根據冒號解釋說明推出。rather than提示對比邏輯，ii空內容根據劃線部分取反推知。或根據邏輯提示，i空和ii空內容取反。
－答案：AF
－單詞：
sketchy adj. 概要的，不完全的
exculpatory adj. 辨明無罪的
flippant adj. 輕率的，輕浮的
cavalier adj. 傲慢的，輕率的
deceptive adj. 欺騙性的，迷惑的

誠然，這份報告是概要性的：報告想要介紹研究的新思路，而非更全面的處理這個研究。
3. 73-4

MRI scans of an elephant’s brain suggest that even relative to its overall size it has a large hippocampus, the component in the mammalian brain linked to memory and an important part of its limbic system, which is involved in processing emotions.
- 解析：

MRI scans of an elephant’s brain suggest that even relative to its overall size it has a large hippocampus, the component in the mammalian brain linked to memory and an important part of its limbic system, which is involved in processing emotions.
－做題關鍵信息：recently暗示時間對比取反，i，ii空聯動。根據第二句話腦科學證實大象具有處理思維能力得出挖空信息。
－答案：CD
－單詞：
fabled adj. 傳奇的，虛構的
limbic adj. 邊緣的
credence n. 可信，真實
dismissal n. 不予理會

－翻譯：
一直以來，只有傳聞軼事可以為大象的思考能力提供佐證，直到最近這些行為被腦科學所證實。對大象大腦的核磁共振掃描顯示，即使相對於大象的體積，其海馬體也是很大的。而海馬體則是關聯記憶和邊緣腦系統中處理感情的重要組成部分。
4. 89-2
It remains a mystery how Theobroma cacao, which scholars believe originated in lowland Amazonia, was introduced to tropical Mesoamerica. It must have been a (i)_____ process: cacao trees do not easily sprout from seed, need years to mature, and grow only in humid lowland forest.Moreover, in a tropical climate, cacao pods spoil quickly, rendering their transport from lowland Amazonia tropical Mesoamerica in a single journey by foot or canoe (ii)_____.
- 解析：
It remains a mystery how Theobroma cacao, which scholars believe originated in lowland Amazonia, was introduced to tropical Mesoamerica. It must have been a (i)_____ process: cacao trees do not easily sprout from seed, need years to mature, and grow only in humid lowland forest. Moreover, in a tropical climate, cacao pods spoil quickly, rendering their transport from lowland Amazonia tropical Mesoamerica in a single journey by foot or canoe (ii)_____.
－做題關鍵信息：三句話為大等價的關係，解釋T cacao植物如何被引入至M地是個謎。冒號後內容解釋i空的引入過程的特點。rendering引導的伴隨狀語具有因果關係提示作用，ii空則通過rendering前的原因推出。
－答案：BD
－單詞：
sprout v. 發芽，生長
pod n. 豆莢
spoil v. 腐壞，破壞
render v. 致使，造成
canoe n. 獨木舟
clandestine adj. 秘密的，暗中的
protracted adj. 持久的，漫長的

redundant adj. 多餘的，過剩的
expeditious adj. 快速有效的
－翻譯：
學者認為源自亞馬孫低地地區的Theobroma cacao是如何被引入到熱帶中美洲的過程，仍然是一個謎。其引進的過程一定很漫長：可可豆樹的種子很難發芽，樹木需要很多年才能長成，且只在潮溼的低地森林才能生長。此外，在熱帶氣候中，可可豆的豆莢會很快腐敗，這使得步行或乘船帶著豆莢從亞馬孫到中美洲是不可能的。

－答案：BD
－單詞：
undistinguished adj. 平凡的，平庸的
hardy adj. 強壯的，適應能力強的
－翻譯：
與流行的傳說相反的是，蟑螂並非格外強壯或具有抗輻射性；實際上，它們和其他昆蟲一樣普通。
