GRE填空中反义重复分为两类，对比关系和转折关系。这里重点讲解GRE填空转折关系，其又分为二类：直接对比和时间对比。下面就跟小编分别来看一下。
GRE填空转折关系
转折关系的特征词为：though (although , even though)，despite (in spite of )，albeit， while (whereas)， notwithstanding， however， nevertheless， nonetheless， whatever， regardless， even if， yet…等。转折关系中可以直接取非，也可以程度取非。统一描述对象没有对立的特征，只有程度差异，这时不填反义词，只填表示程度差异的词。
例1：Although ancient tools were ________ preserved, enough have survived to allow us to demonstrate an occasionally interrupted but generally ________ progress through prehistory.
|
Blank(i) |
Blank(ii) |
|
A superficially |
D continual |
|
B rarely |
E necessary |
|
C needlessly |
F noticeable |
正确答案：BD
答案解析：题目中出现了转折词although，所以空格1应该与enough取非，因为主要是同义事物，所以应该是程度取非。选项中，A表面地;B少量;C没有必要。所以答案选B。
句子主干中出现了but，所以空格2应该与interrupted取反。选项中，D连续的;E必要的;F显著的。所以答案选D。
例2：The labor union and the company’s management, despite their long history of unfailingly acerbic disagreement on nearly every issue, have nevertheless reached an unexpectedly _____, albeit still tentative, agreement on next year’s contract.
A swift
B onerous
C hesitant
D reluctant
E conclusive
nevertheless提示我们前后发生转折，这个题目中语义对应非常明显，disagreement对应agreement，所以我们直接将修饰disagreement的成分取反即可与空格对应，即将long history of unfailingly acerbic中任意属性取反即可。同时，空格修饰agreement，也应该是一个正评价的词。选项中，A快速，敏捷;B繁重;C犹豫的;D不情愿的;E决定性的。后文又出现了tentative表示试探性的，所以不应该是conclusive决定性的这个意思。与"long history"相反选swift。所以答案选A。
例3：Though it would be ______ to expect Barnard to have worked out all of the limitations of his experiment, he must be ______ for his neglect of quantitative analysis.
|
Blank(i) |
Blank(ii) |
|
A impudent |
D pardoned |
|
B unrealistic |
E criticized |
|
C inexcusable |
F acknowledge |
正确答案：BE
答案解析：空格 1 填入一个形容词，表示对空格后面的不定式的修饰;所以空格1所表示的意思应该是 “不现实的”，表示期待巴纳德解决他的实验中的所有缺陷是不现实的，答案选B。
空格 2 填入一个动词，表示因为"他在数量分析中的疏忽"而导致人们对他做的动作，所以空格2应该是一个负向的词汇。所以答案选E。
例4：At first, I found her gravity rather intimidating; but, as I saw more of her, I found that ______ was very near the surface.
(A) seriousness
(B) confidence
(C) laughter
(D) poise
(E) determination
空格要填的是一个名词，它表示“her”的特征，并且这种特征是“洋溢于表面的”(这里的"near the surface"不是“表面上看起来”的意思)。But 表示分号前后是转折关系，空格要表示的含义应该与"gravity"相反。A严肃，庄重;B信心;C笑声;D平衡;E决心。答案C为正确选项。
例5：Current data suggest that, although ______ states between fear and aggression exist, fear and aggression are as distinct physiologically as they are psychologically.
(A) simultaneous
(B) serious
(C) exceptional
(D) partial
(E) transitional
分析：空格填入一个形容词，修饰"恐惧和攻击之间的状态(state between fear and aggression)"，although表示让步转折，空格表达的是和"截然不同(distinct)"相对的概念，但是由于转折不能够前后矛盾，所以空格不能填"相同"的含义，只能表达和"不同"相对的中间状态。A 同时的;B 严肃的;C 例外的，杰出的;D 局部的;E 过渡的。E 选项为正确答案。
考生在做GRE填空三空题时的建议是：
1. 三空题目有些时候给出一些背景，不能忽略;
2. 如果第一空没有思路，先看后面两空，通常后面内容会给出提示信息;
3. 选完答案，通读整个句子，检测答案是否正确。
例题：
1. ______ mushrooms are popular in many cuisines, it is ______ to eat those found in the wild, as many frequently found mushrooms resemble edible mushrooms but are, in fact, ______.
|
Blank(i) |
Blank(ii) |
Blank(iii) |
|
A Considering |
D imprudent |
G poisonous |
|
B While |
E cheaper |
H bland |
|
C Because |
F ingenuous |
I toothsome |
正确答案：BDG
答案解析：我们首先来做空格3，空格3前面有but，表示转折，所以空格3应该与edible取反，表示不能吃。所以答案选G。
根据后面的意思，空格2应该是一个负向的词汇。选项中，D不谨慎的;E便宜的;F天真的。所以答案选D。
最后做第一空格，前后句意思是转折的关系，所以空格1应该是一个表示转折的词汇，所以选B。
例2：Among the factors that ______ the competitiveness of integrated producers are excessive labor, energy, and capital costs, as well as manufacturing ______：Their equipment is odd and less automated, and does not ______ many of the latest refinement in steelmaking technology.
|
Blank(i) |
Blank(ii) |
Blank(iii) |
|
A incorporate |
D inflexibility |
G amalgamate |
|
B Constrain |
E stability |
H intertwine |
|
C are peripheral to |
F tradition |
I incorporate |
正确答案：BDI
答案解析：根据as well as，我们先来做空格2，空格2左边是labor, energy, and capital costs，所以空格2应该是一个负向的词汇。所以选择D。
下面来做空格3，空格3前面有and和does not，所以空格3应该是一个正向的词汇。选项中，G混合;H纠缠;I吸收。所以答案选I。
根据前后意思，空格1也应该是一个负向词汇。选项中，A吸收;B限制;C次要的。所以答案选B。
