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：
A new study suggests that the conversational pace of everyday life may be so brisk it hampers the ability of some children for distinguishing discrete sounds and words and, the result is, to make sense of speech.
(A) it hampers the ability of some children for distinguishing discrete sounds and words and, the result is, to make
(B) that it hampers the ability of some children to distinguish discrete sounds and words and, as a result, to make
(C) that it hampers the ability of some children to distinguish discrete sounds and words and, the result of this, they are unable to make
(D) that it hampers the ability of some children to distinguish discrete sounds and words, and results in not making
(E) as to hamper the ability of some children for distinguishing discrete sounds and words, resulting in being unable to make
选项分析：
(A)it hampers the ability of some children for distinguishing discrete sounds and words and, the result is, to make
【错误1】 句子结构：“it hampers……”和之前“life may be so brisk”两个主谓结构之间本应添加“that”形成“so……that……”结构，由于本选项没有“that”，者两个主谓结构之间的连接方式错误。
【错误2】 固定搭配：” ability for doing sth.”无法表达“做某事的能力”，应为“ability to do sth.”。
(B)that it hampers the ability of some children to distinguish discrete sounds and words and, as a result, to make
【正确】 “to make sense of speech”和“to distinguish discrete sounds and words”平行，两者同为“the ability of some children”的具体内容，表意合理。
【大意】 一项新研究指出日常对话语速太快，妨碍了一些儿童辨别声音并进而理解讲话的能力。
(C)that it hampers the ability of some children to distinguish discrete sounds and words and, the result of this, they are unable to make
【错误1】 代词指代： “this”本意上指代“it hampers the ability……”这一主谓结构，在GMAT所考察的标准书面英语中，代词只能指代与其数量形式一致的名词性结构，因此“this”在此处实际上无所指代。且代词this、that、these、those如果单独使用(“those students”、“that of……”这样的结构就属于不单独使用)，其指代不明，因为书面语不能用手去指这指那。
【错误2】 平行结构：“they are unable to make”之前没有加“that”，根据标准书面英语的规则，它和主句“A new study suggests that……” 被“and”平行在了一起，但两者逻辑含以上并不平行。
(D)that it hampers the ability of some children to distinguish discrete sounds and words, and results in not making
【错误1】 平行结构：“results in not making……”和主句“A new study suggests that……” 被“and”平行在了一起，但两者逻辑含义上并不平行，因此语义逊于(B)。
【错误2】 句子意思：无法根据语法确定“results in not making……”中的“not making……”的逻辑主语一定是“children”，含义的准确性逊于(B)中“the ability of some children to make sense of speech”。
【错误3】 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“not making……”的简洁性逊于(B)中“to make”(动词优于动名词)。
(E)as to hamper the ability of some children for distinguishing discrete sounds and words, resulting in being unable to make
【错误】 固定搭配：类似地，见(A)中【错误2】。
解题思路：
“ability”只有接“to do sth.”才表示“做某事的能力”，因此立即排除(A)和(E)。
(C)中“this”无所指代，立即排除。
(D)中的 “making”简洁性逊于(B)中“to make”，更何况“to distinguish”和“to make”的平行结构十分合理，因此选择(B)。
