GMAT语法实例讲解.

　　GMAT语法对于我们这些学了多年语法的同学往往摸不着头脑，究其原因，一方面是对于一些基础知识的不了解;另一方面不懂得一些基础的解题技巧，为此澳际小编特整理GMAT语法实例讲解，分享给大家，希望对大家有所帮助，文中观点仅供参考。

　　下面给大家简单的举一个例子：(摘自OG第12版659页第6题)

　　In late 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed to visitors for cleaning and repair due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystalizing and fungus was growing on the walls.

　　(A) due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystalizing

　　(B) due to moisture that tourists had exhaled, thereby raising its humidity to such levels that salt from the stone would crystalize

　　(C) because tourists were exhaling moisture, which had raised the humidity within them to levels

　　(D) because of moisture that was exhaled by tourists raising the humidity with them to levels so high as to make the salt from the stone crystalize

　　(E) because moisture exhaled by tourists had raised the humidity within them to such levels that salt from the stone was crystalizing

　　这道题目单从长短上来说，并不能算是语法考试中最长的题目，但很多考生乍一看，就觉得很吓人。我们一起简单的分析一下这个题目。首先，拿到任何一道题，如果你单纯的读完题干、读完每个选项是很难发现任何问题的。我们就以B选项为例：(B) due to moisture that tourists had exhaled, thereby raising its humidity to such levels that salt from the stone would crystalize. 顺着读完，考生基本是找不出来他们所熟悉的语法问题：比如单复数一致、比如时态问题。这也就意味着，读选项的时候一定要把每个选项带回原文去。

　　如果用B选项替换掉原文划线部分，再读这道题：

　　In late 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed to visitors for cleaning and repair (B) due to moisture that tourists had exhaled, thereby raising its humidity to such levels that salt from the stone would crystalize and fungus was growing on the walls.

　　这时候，你会发现这句话主语：the chambers谓语：were closed to visitors，后面的for cleaning and repair是在解释原因，due to moisture也是解释因为潮湿，这个小屋子才被关闭，逗号之后thereby raising its humidity，因此提升了它的潮湿度。问题就是，提升了谁的潮湿度?如果对于前面提到的内容还记得的话，不难判断应该是提升了这个屋子的潮湿度，所以这里的单数代词its指代前面的小屋子the chambers，代词单数，先行词为复数，所以这个代词单复数的问题就被我们发现了。

　　这一点，如果只是读B选项，肯定是不能发现的。再往后读，such that引导了两个结果状语从句：salt from the stone would crystalize跟fungus was growing on the walls.从时态上判断，was growing是采用过去进行时，而would crystalize采用的是过去将来时。既然这两个分局都是跟在such that后面做结果，那么时态上应该也是一致的。所以划线的would crystalize肯定时时态不正确的使用。

　　所有的题目都必须要将其还原到原文当中，联系上下文，只有这样才能帮助我们判断出每个选项对原文划线部分的改写是否符合严格书面英语的要求。其余几个选项，就请考生们自己看看是不是能够判断出来呢?(正确答案为E)

　　以上就是GMAT语法实例讲解的全部内容，值得注意的是如果你没有办法判断一个选项的时候，将他带进句子中进行再来判断，最后祝大家都能考出好成绩。
