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：
Thelonious Monk, who was a jazz pianist and composer, produced a body of work both rooted in the stride-piano tradition of Willie (The Lion) Smith and
Duke Ellington, yet in many ways he stood apart from the mainstream jazz repertory.
(A) Thelonious Monk, who was a jazz pianist and composer, produced a body of work both rooted
(B) Thelonious Monk, the jazz pianist and composer, produced a body of work that was rooted both
(C) Jazz pianist and composer Thelonious Monk, who produced a body of work rooted
(D) Jazz pianist and composer Thelonious Monk produced a body of work that was rooted
(E) Jazz pianist and composer Thelonious Monk produced a body of work rooted both
选项分析：
(A)Thelonious Monk, who was a jazz pianist and composer, produced a body of work both rooted
【错误】 平行结构：“rooted in……”和“Duke Ellington”两者语法功能不一致，因此无法用“both X and Y”的结构平行。
(B)Thelonious Monk, the jazz pianist and composer, produced a body of work that was rooted both
【错误】 平行结构：“in the stride-piano tradition of……”和“Duke Ellington”语法功能不一致，因此无法用“both X and Y”的结构平行。
(C)Jazz pianist and composer Thelonious Monk, who produced a body of work rooted
【错误】 句子结构：“Thelonious Monk”本应做句子的主语，但本选项中它在主句中没有谓语动词，因为“produced”变成了“who”引导的从句的谓语动词。
(D)Jazz pianist and composer Thelonious Monk produced a body of work that was rooted
【正确】 本选项仅仅是“Willie (The Lion) Smith”和“Duke Ellington”用“and”平行在一起，没有使用“both X and Y”的平行结构。
【大意】 爵士钢琴家和作曲家Thelonious Monk创作了一个扎根于Willie (The Lion) Smith和Duke Ellington大幅掠过钢琴弹法的作品体系，但很多方面他又从主流的爵士乐曲中脱颖而出。
(E)Jazz pianist and composer Thelonious Monk produced a body of work rooted both
【错误】 平行结构：见(B)。
解题思路：
(C)中句子结构有问题;
(A)、(B)、(E)没有正确使用“both X and Y”的平行结构，立即排除;
因此选择(D)。
