GMAT语法题，又称句子改错题(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，想要做好语法题难度极高。怎样做好GMAT语法题?下面小编就通过一些经典真题的实例解析，为大家全面讲解GMAT语法题的解题思路和方法技巧。

实例题目：

Although schistosomiasis is not often fatal, it is so debilitating that it

has become an economic drain on many developing countries.

(A) it is so debilitating that it has become an economic

(B) it is of such debilitation, it has become an economical

(C) so debilitating is it as to become an economic

(D) such is its debilitation, it becomes an economical

(E) there is so much debilitation that it has become an economical

选项分析：

(A)it is so debilitating that it has become an economic

【正确】

(B)it is of such debilitation, it has become an economical

【错误1】 句子结构：“it has become……”是一个另起的主谓结构，和之前的只为结构没有任何分句连接词，而仅仅使用“，”相连。

【错误2】 句子意思：“economical”意思是“节约的”而非“经济上的”。

(C)so debilitating is it as to become an economic

【错误】 固定搭配：不存在“so +倒装句+as to……”的用法。

(D)such is its debilitation, it becomes an economical

【错误1】 句子结构：类似地，见(B)中【错误1】。

【错误2】 句子意思：见(B)中【错误2】。

(E)there is so much debilitation that it has become an economical

【错误1】 句子意思：见(B)中【错误2】。

【错误2】

简洁明了：在GMAT语法题中表达同一个意思时，简洁性从高到低依次为动词、形容词和副词、一般名词、动名词(简称VANing原则：V——verb，A——adj.或adv.，N——noun，ing——动名词)，因此“debilitation”(名词)简洁性次于“debilitating”(ing形式的形容词)。

解题思路：

对比选项可知“so/such……that……”是最能准确表达出合理含义的用法，因此选项应在(A)、(E)之间，而(E)的“debilitation”次于(A)的“debilitating”。

因此选择(A)。
