gmat语法，又叫句子改错(sentence correction)，是整个GMAT语文(VERBAL)三大题型中难度最高却也最容易提分的题型。说它难度高，是因为英语语法向来是中国考生的软肋，特别是对于英语基础不扎实的考生来说可谓老大难问题。至于提分容易，则是因为比起出题思路天马行空、文章难度高深莫测且基本没有规律可循的阅读和逻辑来说，GMAT语法无论是考点还是难度，都更有规律，花费同样时间精力复习往往提升更为明显。
话虽如此，想要考好GMAT语法秒解难题还是需要花上一番功夫的。特别是对于考试涉及的各类语法点和疑难杂症，考生势必要多加努力才能有所收获。下面小编就为大家汇总整理了GMAT语法前置与后置形容词考点分析，配合实例解析，为大家每日讲解。
GMAT语法大百科每日语法点：前置与后置形容词的用法说明
1.如果是作为前置形容词:
即形容词位于句首,单独修饰主句的主语.
该形容词的作用和分词一样,逻辑主语必须一致,而且可以还原为完整的句子.
2.如果是作为后置形容词:
既形容词位于修饰对象之后,且两者之间有逗号隔开.
该形容词的作用作为定语就近修饰,可以还原为定语从句.
但如果定语从句中有情态动词,不可以省略为简单的形容词.
而且,后置形容词不可以像现在分词修饰整个句子.
在该种情况下,必须在形容词前面加上具体名词.更多相关内容请点击》GMAT语法句子结构分析。
GMAT前置与后置形容词用法实例讲解
In his research paper, Dr. Frosh, medical director of the Payne Whitney Clinic, distinguishes mood swings,which may be violent without their being grounded in mental disease, from genuine manic-depressivepsychosis.
(A) mood swings, which may be violent without their being grounded in mental disease, from genuine manic-depressive psychosis
(B) mood swings, perhaps violent without being grounded in mental disease, and genuine manic-depressive psychosis
(C) between mood swings, which may be violent without being grounded in mental disease, and genuine manic-depressive psychosis
(D) between mood swings, perhaps violent without being grounded in mental disease, from genuine manic-depressive psychosis
(E) genuine manic-depressive psychosis and mood swings, which may be violent without being grounded in mental disease
选项分析：
首先，这句话用的是一个固定搭配distinguish between x and y，不能用from
另外，定从省略多见于省略(which/that+ is/are/was/were)，有情态动词时似乎不该省略。 而如果理解perhapsviolent without being grounded in mental disease为省略which is,就变成which is perhaps violent without being grounded in mental disease,读的就不顺畅。
所以最后答案是C
