如何备考才能够迅速提升GMAT语法成绩呢?GMAT语法部分的题型有哪些?应该怎样应对呢?下面就来对GMAT语法部分平行并列题型的解题方法进行深入的分析。

　　GMAT的重点题型之一平行并列：

　　平行并列：见到平行看结构，形式功能要对称.就GMAT而言，平行并列是考试中的重点也是难点，英语称其为parallel structure: this is a little bit like making sure that the two sides of a mathematical equation are balance.就解题而言要求做到四个点。

　　形式对称

　　概念对等

　　功能相同

　　含义单一

　　一)形式对称：

　　指平行并列连接词前后的词形式上完全对称

　　下面以GMATpre test 1为例：

　　例1：The airline company, following through on recent warnings that it might start reducing service, announced that it was eliminating jet service to nine cities, closing some unneeded operations, and it grounded twenty-two planes.

　　(A) closing some unneeded operations, and it grounded

　　(B) closing some unneeded operations, and grounding

　　(C) was closing some unneeded operations, while it grounded

　　(D) it closed some unneeded operations and grounded

　　(E) it was closing some unneeded operations, and grounding

　　译文：航空公司遵照最近的警告它可能会开始减少服务而宣布它将会减少喷气机服务到九个城市,关闭不需要的操作和停飞22架飞机。

　　分析：平行并列结构,形式要对称.所以本题答案是B eliminating, closing and grounding 本题重点考查平行并列结构.都是航空公司做的三个动作。

　　例2 The list of animals that exhibits a prerence of either using the right or the lt hand (i.e., claw, paw, or foot) has been expanded to include the lower vertebrates.

　　(A) exhibits a prerence of either using the right or the lt hand (i.e., claw, paw, or foot) has been expanded to include

　　(B) exhibits the prerence to use either the right or the lt hand (i.e., claw, paw, or foot) has been expanded and includes

　　(C) exhibit a prerence in either using the right or the lt hand (i.e., claw, paw, or foot) has been expanded to include

　　(D) exhibit a prerence for using either the right or the lt hand (i.e., claw, paw, or foot) has been expanded to include

　　(E) exhibit the prerence as to either using the right or the lt hand (i.e., claw, paw, or foot) has been expanded and includes

　　译文：动物展示出用左手或右手等的列表已经进一步的扩大到了更为低等的脊椎动物

　　分析：定语从句的主谓一致取决于所修饰对象.前面出现的是animals 所以应该是复数.答案只能在CDE中产生.either or 要求形式是要对称. 而C和E选项中出现了either using or the lt表达错。

　　由此可见GMAT在考查平行并列过程中要求前后严格对称。

　　二)概念对等：

　　平行并列过程中,要求概念要对等,就名词而言,特指对特指,抽象对抽象,具体对具体.它们从来不相互对应进行并列。

　　New theories propose that catastrophic impacts of asteroids and comets may have caused reversals in the Earth’s magnetic field, the onset of ice ages, splitting apart continents 80 million years ago, and great volcanic eruptions.

　　A splitting apart continents

　　B the splitting apart of continents

　　C split apart continents

　　D continents split apart’

　　E continents that were split apart

　　译文：新的理论提出小行星和慧星灾难性的影响可能引地磁场的颠倒，冰川时代的到来，8千万年前大陆的分裂以及火山的喷发。

　　分析：本题平行并列部分是. Reversals , the onset, …. And eruption显然是由动词的抽象名词词形的并列。所以动词的抽象名词表结果，只能和抽象名词并列，而doing强调动做,就splitting apart而言，无名词，所以只能用the splitting apart表达此意。

　　本题选的是B

　　三)功能相同

　　有些特殊题目无法做到形式对称也只能退一步保证功能相同如：

　　scientists have recently discovered what could be the largest and oldest living organism on Earth. A giant fungus that is an interwoven filigree of mushrooms and root like tentacles spawned by a single fertilized spore some 10000 years ago and extending for more than 30 acres in the soil of a Michigan forest.

　　A extending

　　B extends

　　C extended

　　D it extended

　　E is extending

　　译文：科学家最近发现地球上最大的真菌是在Michigan森林中一种被单独受精的孢子所产生的交织混合的蘑菇金银丝和和根状腺毛并且主动向周边土壤延伸30亩。

　　分析：本题中出现了and本来要求前后形式对称。但基于客观事实,产生是被动的而周边延伸却是主动做出的，所以本题选的是extending.虽然形式上不对称.但功能上却是相同的.因为都是分词。

　　四)含义单一

　　重点考查两个题型：

　　1. 从句并列使用相同连词且都补出

　　例:It is well known in supermarket industry that how items are placed on shelves and the frequency of inventory turnovers can be crucial to profits.

　　A the frequency of inventory turnovers can be

　　B the frequency of inventory turnovers is often

　　C the frequency with which the inventory turns over is often

　　D how frequently is the inventory turned over are often

　　E how frequently the inventory turns over can be

　　译文： 在超级市场产业中,货品如何摆放以及存货周期是多少是盈利的关键。分析：and 连接两个平行并列部分，要求形式完全对称,所以答案选择为DE中一个，情态动词不能随意省略添加和改变则答案只有一个是E。因为can表示可能性,如果省略含义发生改变。

　　2. 介词短语并列过程中介词习惯补出原则

　　例:In the fall of 1985, only 10 percent of the women entering college planned to major in education, while 28 percent chose business, making it the most popular major for women as well as for men

　　A as well as for men

　　B as well as the men

　　C and men too

　　D and men as well

　　E and also men

　　译文：在1985年秋天，只有不到10%的女生进入大学计划以教育为主修专业，而28%的人选择进入商业，使得商业成为对于男生和女生最流行选择的学科。

　　分析： as well as 前后形式对称，并列过程中如不补出for这个介词,则容易产生歧义。使人错误的人认为与 the most popular major 并列，加出for则是对于男生和对女生在并列。不会产生多重含义

　　以上就是GMAT语法部分平行并列题型的解题技巧，考生可以据此进行针对性的练习，熟练掌握GMAT语法题目的解题方法，从而在短期内迅速提升GMAT语法成绩。 相关链接：
