GMAT语法题，又称句子改错题(sentence correction)，是整个GMAT考试中对考生英语语法能力考查要求最高的题型，也往往是中国学生最为头疼的一类题目。没有扎实的语法基础和一定的逻辑分析能力，想要做好语法题难度极高。怎样做好GMAT语法题?下面小编就通过一些经典真题的实例解析，为大家全面讲解GMAT语法题的解题思路和方法技巧。
实例题目：
Beyond the immediate cash flow crisis that the museum faces, its survival depends on if it can broaden its membership and leave its cramped quarters for a site where it can store and exhibit its more than 12,000 artifacts.
(A) if it can broaden its membership and leave
(B) whether it can broaden its membership and leave
(C) whether or not it has the capability to broaden its membership and can leave
(D) its ability for broadening its membership and leaving
(E) the ability for it to broaden its membership and leave
选项分析：
(A)if it can broaden its membership and leave
【错误】 固定搭配：在GMAT考察的标准书面英语中，表达“是否”时“whether”优于“if”。
(B)whether it can broaden its membership and leave
【正确】 “whether”引导了从句“it can broaden its membership and leave its cramped quarters for a site……”，“broaden”和“leave”用“and”平行在一起，共同作为“是否”的内容。
【大意】 在当下的现金流危机之外，博物馆的生存取决于其能否拓展其会员并从当前狭窄的地方搬到一个能够储藏其12000余件展品的地方。
(C)whether or not it has the capability to broaden its membership and can leave
【错误】 固定搭配：表达做某事的能力时，“capability”和“capable”应连接“of doing sth.”而非“to do”。
(D)its ability for broadening its membership and leaving
【错误】 固定搭配：表达做某事的能力时，“ability”和“able”应连接“to do”而非“for doing”。
(E)the ability for it to broaden its membership and leave
【错误】 简洁明了：在GMAT语法题中表达同一个意思时，简洁性从高到低依次为动词、形容词和副词、一般名词、动名词(简称VANing原则：V——verb，A——adj.或adv.，N——noun，ing——动名词)。因此(B)中“can”优于(E)中“ability”。
解题思路：
表达是否时有“whether”则必不用“if”，立即排除(A)。
“capability to do”和“ability for doing”是必错搭配，立即排除(C)、(D)。
“ability”简洁性次于“can”，因此选择(B)。
