GMAT语法机经对于很多对于GMAT语法颇感无力的考生来说是个不小的助力，虽然答案都是GMAT考生网友们自己给出，但是参考价值也不小。为此楷维留学指南特意为GMAT考生们分享了2013年2月4日GMAT语法机经，文中观点来自网友仅供参考，希望对大家有所帮助。

　　1.【版本1】语法有很多because or and,并列结构。

　　l 出现并列结构——要立刻想到Parallelism!

　　l 注意介词平行结构

　　1. XX reduced by…, by…, and by…

　　2. 介词在后则注意介词需前后对应：both in…and in…

　　介词在前也要注意后面内容是否对应：in both…and…

　　3.介词短语不是全部都必须一样：leave the money in the drawer and on the table

　　l 注意并列的内容平行

　　1. 动词：both exceeded…and ran….(注意时态)

　　2. to do形式：to suspend…, notify…, and say….

　　to suspend…, to notify…, and to say…

　　V-ing形式：…left quickly, shunning fans and ducking into a car.

　　3. 从句：which has been thawed…and which is still…

　　4. 名词：

　　1) 具体名词只能与具体名词平行;

　　2) 抽象名词与抽象名词平行，也可以与complex gerund phrases平行，但不能simple gerund phrases与平行;

　　3) Simple gerund phrases are Never Parallel to Complex gerund phrases.

　　例：I enjoyed drinking the water and the wine tasting.

　　解析：错误。因为drinking the water是simple gerund phrase，并非名词，只表示动作，而the wine tasting是complex gerund phrase，即ing形式的名词(如marathon running或者the running of marathons)

　　应改成：I enjoyed drinking the water and tasting the wine.

　　5.形容词：The park was neither accessible nor affordable.

　　l 关于because

　　1. because后接句子;

　　2. because of通常接简单的名词，不接句子。若是出现because of sb’s doing一定要改成because;

　　3. because平行

　　prep题：

　　Retailers reported moderate gains in their November sales, as much because of their sales of a year earlier being so bad as that shoppers were getting a head start on buying their holiday gifts.

　　A. of their sales of a year earlier being so bad as that

　　B. of their sales a year earlier having been as bad as because

　　C. of their sales a year earlier being as bad as because

　　D. their sales a year earlier had been so bad as because

　　E. their sales of a year earlier were as bad as that

　　(答案：D as much…as…搭配正确;as much because…as because…平行。)

　　l 关于or：either…or…/neither…nor… (参考1月JJ整理)

　　1. 注意就近修饰原则，谓语动词与or/nor后的名词单复数一致。

　　例：Neither the players nor the coach IS going to the beach.

　　Neither the coach nor the players ARE going to the beach.

　　2. 当neither/either 单独出现 (没有nor/or)，谓语动词用单数。

　　They neither IS…

　　原始：

　　2.【版本1】有关于as much for……as for的平行

　　【版本2】有平行，as.....as......

　　l Parallelism问题请参考1的知识点

　　注意：as…as引导的平行结构中，每个平行成分要概念对等，形式平行。

　　l as much/many…as…

　　1. 可数名词：many、fewer、few、number

　　2. 不可数名词：much、less、little、amount

　　例：Experts estimate that ten times as much petroleum exists in such sources as tar sands, heavy oil, and perhaps even shale as conventional reservoirs.
