GMAT 语法中绝大部分的题目都是一题多考点的出题形式，也就是说每道题目多个选项中均包含着复数的考点。因此考生在解题时也需要根据语法错误的严重程度进行优先级的排序，挑选错误少且不影响较小的选项才是正确做法。下面小编就通过 3 道真题实例为大家讲解。
1. Acid rain and snow result from the chemical reactions between industrial emissions of sulfur dioxide and nitrogen oxideswith 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。

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。
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 ?
GMAT 语法题的难度一方面来自题干，另一方面来自选项，因为我们要依靠 GMAT 语法题选项之间的差别来获得信息、寻求提示，挑选出相对准确而有效的那一个。
以上就是小编为各位考生整理的关于 GMAT 语法解题抓大放小实用思路的介绍，希望考生积极做好备考工作，及时调整好状态，争取在 GMAT 考试中取得理想的成绩 !
