GMAT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，想要做好句子改错题难度极高。如何提升GMAT句子改错题的解题能力?下面小编就为大家整理了一些经典例题，结合实例分析为大家讲解GMAT句子改错题的解题思路和方法技巧。

实例题目：

Gall’s hypothesis of there being different mental functions localized in different parts of the brain is widely accepted today.

(A) of there being different mental functions localized in different parts of the brain is widely accepted today

(B) of different mental functions that are localized in different parts of the brain is widely accepted today

(C) that different mental functions are localized in different parts of the brain is widely accepted today

(D) which is that there are different mental functions localized in different parts of the brain is widely accepted today

(E) which is widely accepted today is that there are different mental functions localized in different parts of the brain

选项分析：

(A)of there being different mental functions localized in different parts of the brain is widely accepted today

【错误】 句子意思：“there being”既不具有简洁性，也无法用作叙事表达“hypothesis”的内容，因此表意不佳。

(B)of different mental functions that are localized in different parts of the brain is widely accepted today

【错误】 句子意思：“hypothesis of different mental functions that are localized in different parts of the brain”无法表达本意上的“不同思维功能位于大脑不同部分的假说”这一含义，因为介词“of”连接的是一个名词性结构而非主谓结构，其核心词为“different mental functions”中的“functions”，“that are localized in different parts of the brain”仅仅是“functions”的修饰语。因此本选项的这一结构只能被翻译为“谓语大脑不同部分的思维功能的假说”，表意并不合理。

(C)that different mental functions are localized in different parts of the brain is widely accepted today

【正确】 “that different mental functions are localized in different parts of the brain”是修饰“hypothesis”的同位语从句。“hypothesis”是主句主语，“is widely accepted”是主句谓语。

【大意】 Gall的不同思维功能位于大脑不同部分的假说如今被广泛接受。

(D)which is that there are different mental functions localized in different parts of the brain is widely accepted today

【错误】 简洁明了：“which is”结构修饰“hypothesis”并没有带来任何增量的信息，完全可以删去，本选项完全可以改写为“hypothesis that……is widely accepted today”，因此其不具有简洁性。

(E)which is widely accepted today is that there are different mental functions localized in different parts of the brain

【错误】 简洁明了：“which is”结构修饰“hypothesis”并没有带来任何增量的信息，完全可以删去，本选项完全可以改写为“……hypothesis widely accepted is that”，因此其不具有简洁性。

解题思路：

其他选项在表意准确性合理性或简洁性上逊于(C)，因此选择(C)。
