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：
There are several ways to build solid walls using just mud or clay, but the most extensively used method has been the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid in the wall in mud mortar.
(A) the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid
(B) forming the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them
(C) having bricks formed from mud or clay, and, after some preliminary air drying or sun drying, they were laid
(D) to form the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them
(E) that bricks were formed from mud or clay, which, after some preliminary air drying or sun drying, were laid
选项分析：
(A)the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid
【错误】 平行结构：由日常逻辑判断可知，“the forming of bricks out of mud or clay”和“they(bricks) are laid”用“and”连接，其实是砌墙的两个步骤，其逻辑含义应该是平行的，但语法结构上两者并不平行。
(B)forming the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them
【错误】 平行结构：类似地，见(A)中。
(C)having bricks formed from mud or clay, and, after some preliminary air drying or sun drying, they were laid
【错误】 平行结构：类似地，见(A)中。
(D)to form the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them
【正确】 “to form……”和“to lay them……”正确地用“and”平行在一起。且与“ways to build solid walls……”含以上搭配。
【大意】 存在集中仅用泥和粘土砌墙的方法，但最为广泛使用的方法是将你和粘土做成砖，并且在风干或晒干之后，混合泥浆垒城墙。
(E)that bricks were formed from mud or clay, which, after some preliminary air drying or sun drying, were laid
【错误】 修饰成分：给选项将砌墙的两个步骤以“主句+which+从句”的修饰关系呈现，语义上已逊于(D)。不仅如此，“which”引导的是定语从句，其本质是定语，即名词的修饰语，名词修饰语要尽量保证和所修饰名词就近，尽量避免跳跃修饰，本选项中“which”引导的定语从句要跳跃修饰“bricks”，因此逊于既平行又避免了跳跃修饰的选项(D)((D)未使用修饰)。
解题思路：
(A)、(B)、(C)、(D)中只有(D)平行，且平行结构的语义很合理。
(E)不用平行，且“which引导的从句”跳跃修饰，因此选择(D)。
