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：
Yellow jackets number among the 900 or so species of the world’s social wasps, wasps living in a highly cooperative and organized society where they consist almost entirely of females—the queen and her sterile female workers.
(A) wasps living in a highly cooperative and organized society where they consist almost entirely of
(B) wasps that live in a highly cooperative and organized society consisting almost entirely of
(C) which means they live in a highly cooperative and organized society, almost all
(D) which means that their society is highly cooperative, organized, and it is almost entirely
(E) living in a society that is highly cooperative, organized, and it consists of almost all
选项分析：
(A)wasps living in a highly cooperative and organized society where they consist almost entirely of
【错误】 句子意思：根据日常逻辑“consist”合理的主语应为“society”，表意为“黄蜂社会主要有雌蜂组成”。但“they consist almost entirely of females”中“they”无法指代“society”，只能指代“wasps(黄蜂)”，但“黄蜂”并不是由“雌蜂”组成的——“黄蜂”(即使是复数)只能由黄蜂头、黄蜂腹部、黄蜂翅膀等“组成”，不能由雌蜂“组成”。
(B)wasps that live in a highly cooperative and organized society consisting almost entirely of
【正确】 “that”引导的定语从句修饰了“wasps”，而这个“wasps”又进一步作同位语修饰“the world's social wasps”，修饰关系明确合理。
【大意】 小黄蜂名列世界900多种社会性黄蜂，生活在一个高度合作的、有组织的主要由雌性——蜂后和不育的雌工蜂组成的社会中的黄蜂。
(C)which means they live in a highly cooperative and organized society, almost all
【错误1】 修饰成分：从句“which means……”本意想修饰“Yellow jackets number among the 900 or so species of the world's social wasps”整个主谓结构。但在GMAT考察的标准书面英语中，“which”只能引导修饰某个名词性结构的定语从句，而不能修饰整个主谓结构。
【错误2】 修饰成分：“almost all females”是一个名词性结构，但并不是主谓结构的一部分，因此只能是一个修饰语，但其修饰对象并不明确，是一个孤立的名词性结构。
(D)which means that their society is highly cooperative, organized, and it is almost entirely
【错误1】 修饰成分：见(C)中“修饰成分”第一项。
【错误2】 句子意思：“it is almost entirely females”中“it”指代“society”，但“社会”无法是“雌蜂”，而只能是“雌蜂的社会(society of females)”，因此表意不合理。
(E)living in a society that is highly cooperative, organized, and it consists of almost all
【错误】 平行结构：“it consists of almost all females”并不应是一个和主句之间用“and”连接的平行对象，因为它与主句含义并不对等，实际上，其表述的内容应作为与“cooperative, organized”平行，共同修饰“society”的修饰成分。
解题思路：
“which means……”不能修饰整个主谓结构，立即排除(C)、(D)。
(E)中“and”连接的结构逻辑含义上不对等，排除。
对比(A)、(B)，(A)的表意逊于(B)，因此选择(B)。
