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：
According to a recent poll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, like that of earlier generations.
(A) like that of earlier generations
(B) as that for earlier generations
(C) just as earlier generations did
(D) as have earlier generations
(E) as it was of earlier generations
选项分析：
(A)like that of earlier generations
【错误】 句子意思：语法上没有比较结构“like that of earlier generations”与“a goal of a majority of young adults”，但“like”用于比较仅仅能表达“that(the goal)of earlier generations”与“a goal of a majority of young adults”相似，并不能向(E)表达“owning and living……”是“a goal of a majority of young adults”就像“it”(平行指代“owning and living……”)是“that of earlier generations”的含义。因此表意逊于(E)
(B)as that for earlier generations
【错误】 比较结构：本选项本意是用“as”引导比较句式，并对“as”之后的比较从句进行省略。如果我们将省略得部分不全，那么完整的比较句式应该是：owning and living in a freestanding house on its own land is still a goal of a majority of young adults，as it(指代“owning and living……”) was that(指代“a goal”)for earlier generations。然而本选项将“it was”省略，使我们我发确定“that for earlier generations”是在与“a goal of a majority of young adults”平行作为比较从句“was”之后的标语，因此产生了比较歧义——本选项还可能表达：owning and living in a freestanding house on its own land is still a goal of a majority of young adults，as that(指代“a goal”)for earlier generations is a goal of a majority of young adults。
(C)just as earlier generations did
【错误】 比较结构：“earlier generations did”与“owning and living in a freestanding house on its own land is still a goal of a majority of young adults”两个主谓结构不具有可比性，无法用“just as”比较。
(D)as have earlier generations
【错误】 比较结构：“earlier generations have”与“owning and living in a freestanding house on its own land is still a goal of a majority of young adults”两个主谓结构不具有可比性，无法用“as”比较。
(E)as it was of earlier generations
【正确】 本选项正确使用了比较句式，补齐省略部分两个平行可比的主谓结构为“owning and living……is still a goal of a majority of young adults, as it(平行指代‘owning and living……’)was(a goal)of earlier generations”，比较关系明确合理。
【大意】 根据最近民调，拥有并住在一个独栋房子中仍然是主流成年人的目标，就像其曾是早代人的目标一样。
解题思路：
看见比较找比较对象，比较对象如果不是平行且可比的就要排除选项。本题中只有“owning and living in a freestanding house on its own land is still a goal of a majority of young adults, as it was of earlier generations”是正确的，省略后的比较句式，其中“it”指代“owning and living……”，因此“it was”与前半句的“owning and living……is”平行，“of earlier generations”与前半句中“of a majority of young adults”平行，而“it was”与“of”之间省略了“a goal”，但这种省略并没有产生歧义。(A)选项虽然没有明显语法错误，但表意没有(E)准确合理，因此选择(E)。
