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：
A leading figure in the Scottish Enlightenment, Adam Smith’s two major books are to democratic capitalism what Marx’s Das Kapital is to socialism.
(A) Adam Smith’s two major books are to democratic capitalism what
(B) Adam Smith’s two major books are to democratic capitalism like
(C) Adam Smith’s two major books are to democratic capitalism just as
(D) Adam Smith wrote two major books that are to democratic capitalism similar to
(E) Adam Smith wrote two major books that are to democratic capitalism what
选项分析：
(A)Adam Smith's two major books are to democratic capitalism what
【错误】 修饰成分：“A leading figure in the Scottish Enlightenment”大意为“苏格兰启蒙运动的领军人物”，应当是作同位语修饰“Adam Smith's”，但“Adam Smith's”不是名词而仅仅是名词所有格，因此无法被同位语修饰。
(B)Adam Smith's two major books are to democratic capitalism like
【错误】 修饰成分：类似地，见(A)。
(C)Adam Smith's two major books are to democratic capitalism just as
【错误】 修饰成分：类似地，见(A)。
(D)Adam Smith wrote two major books that are to democratic capitalism similar to
【错误】 句子结构：划线部分之后“Marx's Das Kapital is to socialism”是一个主谓结构，和之前的主谓结构“that are to democratic
capitalism”之间应当有分句连接词，而不是仅仅用“similar to”连接。
(E)Adam Smith wrote two major books that are to democratic capitalism what
【正确】 “A leading figure in the Scottish Enlightenment”正确地作同位语就近修饰“Adam Smith”。
【大意】 苏格兰运动的领军人物亚当斯密所著的两本书之于民主资本主义有如马克思的资本论之于社会主义。
解题思路：
“A leading figure”只能修饰“Adam Smith”，立即排除(A)、(B)、(C)，(D)的句子结构有问题，立即排除，因此选择(E)。
