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：
Retail sales rose 0.8 of 1 percent in August, intensifying expectations that personal spending in the July–September quarter more than doubled that of the 1.4 percent growth rate in personal spending for the previous quarter.
(A) that personal spending in the July–September quarter more than doubled that of
(B) that personal spending in the July–September quarter would more than double
(C) of personal spending in the July–September quarter, that it more than doubled
(D) of personal spending in the July–September quarter more than doubling that of
(E) of personal spending in the July–September quarter, that it would more than double that of
选项分析：
(A)that personal spending in the July-September quarter more than doubled that of
【错误1】 代词指代：此处代词“that”只能指代“personal spending”，因此与题干中“1.4 percent growth rate”之后的“personal spending”重叠，直译过来大意为“个人消费翻番个人消费中个人消费的1.4%的增长率”，本质上是赘余的。
【错误2】 动词时态：“that”引导的同位语从句描述了“expectations”的内容，因此过去将来时(B)中“would”与其含义更加匹配，表达出“站在过去向前看”的含义，因此本选项表意逊于(B)。
(B)that personal spending in the July-September quarter would more than double
【正确】 “that”引导的从句“personal spending in the July-September quarter would more than double……”正确地作同位语修饰了“expectations”，表达了“预期”的具体内容。
【大意】 零售销售额在八月增长了0.8%，加强了个人支出在7-9月这个季度会将上季度1.4%的个人消费增长率翻番的预期。
(C)of personal spending in the July-September quarter, that it more than doubled
【错误】 句子意思：“of personal spending”修饰“expectations”，合起来大意为“个人消费的预期”，由日常逻辑“Retail sales”的增长加剧的并不是对“个人消费”本身的预期，而是对“个人消费会将增长率翻番”这件事的预期，因此本选项表意逊于(B)。
(D)of personal spending in the July-September quarter more than doubling that of
【错误】 句子意思：见(C)。
(E)of personal spending in the July-September quarter, that it would more than double that of
【错误】 句子意思：见(C)。
解题思路：
用“that”引导的同位语(名词性)从句描述“expectation”的内容表意更加准确合理，所以排除(C)、(D)和(E)。
(B)中的“would”时态上优于(A)。
因此选择(B)。
