GMAT语法知识点详解：with用法.

　　GMAT语法知识点中with用法看似简单，其实往往很容易搞错。with不仅仅可以作为介词，而且可以with符合结构与独立主格结构，希望给各位提供一些帮助。时间仓促，内容难免有所纰漏，望大家批评指正。

　　一、含糊不清的地方——with复合结构与独立主格结构

　　看很多同学都对这一GMAT语法知识点中的with的独立主格结构搞不清楚。严格来讲，那叫with的复合结构，在句中可作状语、定语，看这2个句子：

　　With time permitting, we will visit the Summer Palace.=Time permitting, we will visit the Summer Palace.(句中作状语时)

　　The girl with an apple in her hand is my sister.(此处就不是独立主格结构，作定语)

　　二、别忘了with作介词的基本功能

　　有十多项意思，英汉字典上都有，具体意思可以不记，理解它既可以对前面的名词修饰，也可以对前面整个句子修饰，如：

　　prep191：For the last five years the Dutch economy has grown faster than Britain, France, or Germany, with the unemployment rate having remained well below that of the other three countries.

　　A.Britain, France, or Germany, with the unemployment rate having remained

　　B.have those of Britain, France, or Germany, and the unemployment rate remaining

　　C.have Britain, France, and Germany, and the unemployment rate has remained

　　D.the economy of Britain, France, and Germany, with the unemployment rate that has remained (E)

　　E.the economies of Britain, France, and Germany, and the unemployment rate has remained

　　对于D的解释说逻辑主语问题，就是因为with作介词，意为“具有”是修饰Dutch Economy的，故不对。而改成with ..remaining..又无法与完成时伴随。

　　又如：prep193：As the honeybee’s stinger is heavily barbed, staying where it is inserted, this results in the act of stinging causing the bee to sustain a fatal injury.

　　A.As the honeybee’s stinger is heavily barbed, staying where it is inserted, this results in the act of stinging causing

　　B.As the heavily barbed stinger of the honeybee stays where it is inserted, with the result that the act of stinging causes

　　C.The honeybee’s stinger, heavily barbed and staying where it is inserted, results in the fact that the act of stinging causes

　　D.The heavily barbed stinger of the honeybee stays where it is inserted, and results in the act of stinging causing(E)

　　E.The honeybee’s stinger is heavily barbed and stays where it is inserted, with the result that the act of stinging causes

　　这里的with 是对前面整句修饰。

　　一般而言，对于with用法这一GMAT语法知识点最为常见的就是介词用法，且使用比较多。但往往最让人混淆的是with的复合结构的使用，考生可对于这类用法找一些句子进行练习，相信这个问题很快将引刃而解。最后祝大家都能考出好成绩。
