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：
Unlike the conviction held by many of her colleagues that genes were relatively simple and static, Barbara McClintock adhered to her own more complicated ideas about how genes might operate, and in 1983, at the age of 81, was awarded a Nobel Prize for her discovery that the genes in corn are capable of moving from one chromosomal site to another.
(A) Unlike the conviction held by many of her colleagues that genes were
(B) Although many of her colleagues were of the conviction of genes being
(C) Contrary to many of her colleagues being convinced that genes were
(D) Even though many of her colleagues were convinced that genes were
(E) Even with many of her colleagues convinced of genes being
选项分析：
(A)Unlike the conviction held by many of her colleagues that genes were
【错误】 比较结构：比较对象应平行可比，而“Unlike”所比较的两个对象是“conviction”和“Barbara McClintock”，不具有可比性。
(B)Although many of her colleagues were of the conviction of genes being
【错误1】 句子意思： “genes being relatively simple and static”无法表达预期的“基因是相对简单且静止的”的含义，而只能表达“相对简单且静止的基因”，因为这个结构的核心词，也就是含义的重心，是“genes”，而“being relatively simple and static”是其定语而已。因此，用这个结构修饰“conviction”(“确信”)的内容，表意不佳。
【错误2】 简洁明了：“being”作修饰语时不具有简洁性。
(C)Contrary to many of her colleagues being convinced that genes were
【错误】 简洁明了：见(B)中(2)。
(D)Even though many of her colleagues were convinced that genes were
【正确】 “Even though”引导了让步状语从句“many of her colleagues were convinced”，“that genes were relatively simple and static”是“convinced”连接的从句，用来说明“convinced”的具体内容。
【大意】 即便很多她的同事确信基因是相对简单而静止的，Barbara McClintock坚持她有关基因如何运作的复杂观点，并于1983年，在她81岁时，因她曾发现玉米的基因能从一个染色体跳到另一个而被授予诺贝尔奖。
(E)Even with many of her colleagues convinced of genes being
【错误1】 句子意思： 类似地，见(B)中【错误1】。
【错误2】 简洁明了：见(B)中【错误2】。
解题思路：
“unlike”连接比较对象须平行可比，因此立即排除(A)。
(D)没有明显错误，而剩下的选项均使用了“being”这一不简洁的结构作为修饰语，因此选择(D)。
