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：
Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year – they are often green and striped, or have plenty of bumps and bruises – heirlooms are more flavorful and thus in increasing demand.
(A) Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
(B) Although heirloom tomatoes, grown from seeds saved during the previous year, appear less appetizing than most of their round and red supermarket cousins
(C) Although they appear less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
(D) Grown from seeds saved during the previous year, heirloom tomatoes appear less appetizing than most of their round and red supermarket cousins
(E) Heirloom tomatoes, grown from seeds saved during the previous year, although they appear less appetizing than most of their round and red supermarket cousins
选项分析：
(A)Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
【错误】 句子结构：双破折号属于插入语，添加之后对其他部分的句子结构不造成任何影响。本选项中“heirloom tomatoes”没有自己的谓语动词，跳过双破折号后，新的主谓结构“heirlooms are more flavorful……”开始，因此本选项主谓结构不完整。
(B)Although heirloom tomatoes, grown from seeds saved during the previous year, appear less appetizing than most of their round and red supermarket cousins
【正确】
(C)Although they appear less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
【错误】 句子结构：类似地，见(A)中“句子结构”，“heirloom tomatoes”没有谓语动词。
(D)Grown from seeds saved during the previous year, heirloom tomatoes appear less appetizing than most of their round and red supermarket cousins
【错误】 句子结构：双破折号属于插入语，添加之后对其他部分的句子结构不造成任何影响。因此将这一部分删去后考察句子结构，发现“heirloom tomatoes appear less appetizing……”与“heirlooms are more flavorful……”两个主谓结构之间没有任何分句连接词，因此这两个结构的连接方式有问题。
(E)Heirloom tomatoes, grown from seeds saved during the previous year, although they appear less appetizing than most of their round and red supermarket cousins
【错误】 句子结构：类似地，见(A)中“句子结构”，“heirloom tomatoes”没有谓语动词。
解题思路：
分析选项的第一步是分析句子结构，在GMAT句子改错题中，句子结构的错误只有两种——主谓结构(即分句)内部有错误，或主谓结构之间的连接方式有错误。(A)、(C)、(E)中主谓结构内部不完整，(D)中两个主谓结构连接方式有错误。因此选择(B)。
