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：
A surge in new home sales and a drop in weekly unemployment claims suggest that the economy might not be as weak as some analysts previously thought.
(A) claims suggest that the economy might not be as weak as some analysts previously thought
(B) claims suggests that the economy might not be so weak as some analysts have previously thought
(C) claims suggest that the economy might not be as weak as have been previously thought by some analysts
(D) claims, suggesting about the economy that it might not be so weak as previously thought by some analysts
(E) claims, suggesting the economy might not be as weak as previously thought to be by some analysts
选项分析：
(A)claims suggest that the economy might not be as weak as some analysts previously thought
【正确】
(B)claims suggests that the economy might not be so weak as some analysts have previously thought
【错误】 主谓一致：动词“suggests”的主语是“a surge in new home sales and a drop……”，其核心词为“a surge and a drop”，是一个复数概念，因此主谓不一致。
(C)claims suggest that the economy might not be as weak as have been previously thought by some analysts
【错误】 主谓一致：“have been previously thought”的逻辑主语是“economy”，主谓不一致。
(D)claims, suggesting about the economy that it might not be so weak as previously thought by some analysts
【错误】 句子结构：“suggesting”单独不能做谓语动词，则主语“a surge in new home sales and a drop……”没有谓语动词，主谓结构不完整。
(E)claims, suggesting the economy might not be as weak as previously thought to be by some analysts
【错误】 句子结构：见(D)。
解题思路：
(D)和(E)句子结构出问题，应立即排除。
(B)的主谓不一致立即排除。
(C)句子结构有些复杂“as have been previously thought”似乎是一个没头没尾的东西，但可以看出“have been previously thought”应该是某个发生省略的从句的谓语动词，由此发现其逻辑主语是“economy”，于是发现主谓不一致，立即排除。
因此选择(A)。
