摘要：GMAT语法改错题的选项判断方式不同于其它语法考试，并不是简单的看选项的绝对对错来进行选择的，很多时候正确选项不止一个，也有些情况所有选项都多多少少存在一定问题。本文将结合3道GMAT语法真题实例分析选项对错判断和取舍的正确思路。

GMAT语法中绝大部分的题目都是一道题目包含多个考点，而这些考点分布在各个选项中的出题形式。因此考生往往会陷入需要对复数考点同时判断其对错并进行取舍选择的困境当中。如何才能找到正确答案？下面小编就通过3道GMAT语法改错真题精解为大家分析语法选项取舍的正确思路。

GMAT语法改错精解：逻辑关系错误大于用词不当

1. Acid rain and snow result from the chemical reactions between industrial emissions of sulfur dioxide and nitrogen oxides with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids.

(A)with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids.

(B)with atmospheric water vapor producing highly corrosive sulfuric and nitric acids.

(C)and atmospheric water vapor which has produced highly corrosive sulfuric and nitric acids.

(D)and atmospheric water vapor which have produced sulfuric and nitric acids which are highly corrosive.

(E)and atmospheric water vapor to produce highly corrosive sulfuric and nitric acids.

这道题目的考查对象为between…and…这一常见的固定搭配，用来连接两个名词或名词短语，本题对考生的干扰主要在于sulfur dioxide和nitrogen oxides中间已经出现了一个and，有些考生就想到GMAT语法要求句子简明，那么连用and肯定不合适，首先将C,D和E排除掉了。

但是如果用 with，整句话逻辑关系不通，这个错误当然要比用词重复严重得多，相比之下还是选择使语意合乎逻辑的选项，正确答案为E。我们不选C和D的理由并不是由于句子不简洁，而是其逻辑关系有误。

GMAT语法改错精解：保证句意完整再看词汇问题

2. A majority of the international journalists surveyed view nuclear power stations as unsafe at present but that they will, or could, be made sufficiently safe in the future.

(A)that they will,or could

(B)that they would,or could

(C)they will be or could

(D)think that they will be or could

(E)think the power stations would or could

题干中的but表转折关系，在对选项进行比较时A,B,C比较容易吸引考生眼球，因为它们与划线句相似，D和E凭空多出个think，让人感觉难以接受，但是如果仅仅以这个理由进行排除显然是证据不足的。

我们应该先分析原句结构，抓住主线，该句属于平行结构形式，D和E中的think与view在意思上形成对应，所以我们不应对这两个答案带有任何偏见，而应一视同仁。

根据GMAT攻略，不能随意省略成分，否则句意就会出现ambiguity。比较五个选项，只有D的句意表达最完整。而为什么要使用think一词我们大可不必去追究，这只是无关痛痒的小问题。

GMAT语法改错精解：句子重心改变比用词重复更严重

3. Unlike the acid smoke of cigarettes, pipe tobacco, cured by age-old methods, yields an alkaline smoke too irritating to be drawn into the lungs.

(A) Unlike the acid smoke of cigarettes,pipe tobacco,cured by age-old methods,yields an alkaline smoke.

(B) Unlike the acid smoke of cigarettes,pipe tobacco is cured by age-old methods,yielding an alkaline smoke.

(C)Unlike cigarette tobacco,which yields an acid smoke,pipe tobacco,cured by age-old methods,yields an alkaline smoke.

(D) Differing from cigarettes’ acid smoke,pipe tobacco’s alkaline smoke,cured by age-old methods.

(E) The alkaline smoke of pipe tobacco differs from cigarettes’ acid smoke in that it is cured by age-old methods and is.

解答本题时首先排除的是D答案，因为differ from不能用在句首。本题的正确答案为C，但是很多考生的目光都是在C上暂作停留就转向其他选项了。

原因是C中连用了两个yield，这样的句子毫无美感可言，缺乏变化。可是千万别忘记考虑到句子重心问题，其他几个答案都是把句子重心搞错了，smoke和cigarette对应有误，这可是大禁忌，比起这个错误来，用词重复还算得了什么呢?

以上就是小编为大家介绍的GMAT语法改错选项判断和取舍的正确思路分析，结合真题希望能够给大家带来更为直观明确的概念。GMAT语法的解题思路并非简单而绝对的对错判断，而是再多个考虑因素中寻求最为合适的选项，这其中的差异还希望大家能够尽早认清和适应。
