想要迅速提高GMAT语法考试成绩，考生就需要熟练掌握一些GMAT语法考试中的必备知识点，并在解题的过程中灵活运用。下面就来对GMAT语法考试中的必备知识点进行简单的介绍，希望能够为同学们备考GMAT语法考试带来帮助。

　　现在分词可以后置作为定语或则状语.

　　而如果是形容词后置,那么该形容词的修饰对象反而觉得好象不是很明确.

　　比如:

　　OG 15

　　15. 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-depressive psychosis.

　　(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

　　Answer to Question 15

　　The best choice is C because it uses the idiomatically correct expression distinguishes between x and y and because it provides a structure in which the relative clause beginning which may be violent clearly modifies mood swings. The other choices use distinguishes in unidiomatic constructions. Additionally, their in A is intrusive and unnecessary, and the modifier of mood swings in B and D (perhaps violent) is awkward and less clear than the more developed clause which may be violent.

　　这个解释看得不是很明白.

　　我原本以为是:如果形容词修饰名词,不应该用逗号隔开,而应该直接接在名词的后面,这样能更明确一些.

　　可是OG 18

　　18. Each of Hemingway&aposs wives--Hadley Richardson. Pauline Pfeiffer. Martha Gelhom. and Mary Welsh --were strong and interesting women, very different from the often pallid women who populate his novels.

　　(C) Hemingway&aposs wives--Hadley Richardson, Pauline Pfeiffer, Martha Gelhom, and Mary Welsh--were all strong and interesting women,

　　在这边,形容词different就后置,而且根据意思应该是修饰该句的主语Hemingway&aposs wives.

　　为什么不会产生歧义就近修饰all strong and interesting women.

　　虽然修饰哪一个看起来好象对原句意思的理解没有什么影响.

　　还有一道题目:

　　OG 38

　　38. Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the growth of industrial activity there.

　　(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there

　　(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings

　　(C) Baltic Sea sediments, findings consistent with its growth of industrial activity

　　(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area

　　(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there

　　All of the choices but D contain ambiguities. In A and B the words which and where appear to rer to sediments, and in E it is not clear what consistent describes. In A, C, and E, there is no logical place to which there or its could rer. In D, the best choice, the phrase sediments from the Baltic Sea tells where the sediments originate, findings provides a noun for consistent to modify, and in the area clearly identifies where the industrial activity is growing.

　　照OG的解释,形容词后置应该是没有办法像现在分词一样作为一种伴随结果修饰正个句子的，所以正确答案D在consistent的前面加上了finds.

　　以上对GMAT语法考试中的常见备考要点进行了较为详细的阐述，考生不妨以此为鉴，通过反复练习逐步掌握其在GAMT语法考试中的使用规律，从而在GMAT语法考试中发挥出更好的水平。 相关链接：
