在GMAT语法备考的过程中，考生需要通过大量练习来逐步掌握GMAT语法的解题技巧。以下将通过几个例题来为大家介绍一下GMAT语法的解题思路和技巧，希望能够为正在备考GMAT考试的考生提供帮助。

　　39. 一个具有迷惑性的平行OG62. Geologists believe that the warning signs for a major earthquake may include sudden fluctuations in local seismic activity, tilting and other dormations of the Earth&aposs crust, changing the measured strain across a fault zone, and varying the electrical properties of underground rocks.

　　(A) changing the measured strain across a fault zone and varying

　　(B) changing measurements of the strain across a fault zone, and varying

　　(C) changing the strain as measured across a fault zone, and variations of

　　(D) changes in the measured strain across a fault zone, and variations in

　　(E) changes in measurements of the strain across a fault zone, and variations among

　　首先tilting根据后面并列的名词看出是名词, 但是紧跟的and会造成并列已经结束的假象, 这里要明白并列中间的东西也可以用and连接.

　　另外一个: The suspect in the burglary was advised of his right to remain silent, told he could not leave, and was interrogated in a detention room.

　　(A) of his right to remain silent, told he could not leave, and was

　　(B) of his right to remain silent, told he could not leave, and (B)

　　(D) that he had a right to remain silent, could not leave, and was

　　D的语意不对, 后面两个动作不用建议, 且主被动平行相对awkward.

　　40. OG89. A recent national study of public schools shows that there are now one microcomputer for every thirty-two pupils, four times as many than there were four years ago.

　　(A) there are now one microcomputer for every thirty-two pupils, four times as many than there were (C)

　　(B) there is now one microcomputer for every thirty-two pupils, four times as many than there were

　　(C) there is now one microcomputer for every thirty-two pupils, four times as many as there were

　　(D) every thirty-two pupils now have one micro computer, four times as many than there were

　　(E) every thirty-two pupils now has one microcom puter, four times as many as

　　DE的four times作为一个后置成分, 修饰前面的one逻辑错误; ABC利用there be表示比率, 将这个问题避开.

　　41. OG103. Students in the metropolitan school district lack math skills to such a large degree as to make it difficult to absorb them into a city economy becoming ever more dependent on information-based industries.

　　(A) lack of math skills is so large as to be difficult to absorb them into a city&aposs economy that becomes

　　(B) are so lacking in math skills that it will be difficult to absorb them into a city economy becoming (B)

　　lack在原句里面是动词, A将其变成了N, 造成了前面的主语成了Dangling element, 这种错误要意识到, 同理OG228CDE; 而且OG103A它也使后面的them指代错误 (因为主语变了, 对于这种变更造成的影响要注意).

　　42. 主谓宾结构中, 复数主语可以对应单数宾语, Eg. We’are a team.

　　43. it be adj. for x to do y 是ETS喜欢的结构, 其中it是形式主语.

　　44. 另外, OG160是用while引出了两个句子的平行, 再用and引出第三个, 比较灵活的平行和句子连接, 结构看清楚.

　　45. It is an oversimplified view of cattle raising to say that all one has to do with cattle is leave them alone while they feed themselves, corral them, and to drive them to market when the time is ripe.

　　(C) all one has to do with cattle is leave them alone while they feed themselves and then corral them and

　　(D) the only thing that has to be done with cattle is leave them alone while they feed themselves, corral them, and (C)

　　首先观察结构, D中的corral them是并列在分句下面, 而分句的主语是they, 明显是错误的, 但是C就用and去和主句并列, 解决了这个问题(注意C的and then是和leave组合并列再和drive并列). 另外, all one has to do with cattle is leave这里leave前省略了to, 同理可能还有what从句 is (to) do, 类似例句:

　　All I can do is watch you leave. OG244选项C: one thing they have had to do is work, 尽管这是个错误的选项但og没有指出work前要加to.

　　46. 不要被插入语迷惑, 大全537, that is是插入语, 后面仍然是修饰mechanisms的定语从句.

　　47. for后面接doing一般表示sth的用途, eg.it’s a knife for slicing bread; 表示目的, 还是不定式最好, 因此当for doing和不定式同时出现时, 选择不定式, OG112BD, OG160CE, OG239AC, OG204BE; for+名词结构表示目的也是正确的, Eg.Several million tons of stone were quarried in France for the building of eight cathedrals.

　　48. 明确修饰对像很重要, OG119DE就是没有明确, 导致significant in compunding不能作为状语修饰前面的动词is growing.

　　49. 主句放在句末头重脚轻, confusing, OG27E.

　　50. What is difficult to understand is A.;What are difficult to understand are A and B, OG211B.

　　51. 大全431, 相同的形容词要放在前面, 对比AB; 如果是形容词的话并列的话就是: both public and private employee.

　　52. 建立一种思想: SVO结构完整, 即”谁, 怎么样”, OG192E就是结构不完整, 话没有说完;

　　同理: OG71. The original building and loan associations were organized as limited life funds, whose members made monthly payments on their share subscriptions, then taking turns drawing on the funds for home mortgages.

　　(A) subscriptions and then took turns drawing

　　(B) subscriptions and then took turns, they drew

　　(C) subscriptions and then drew, taking turns (C)

　　BC的错误在于take turns干什么? Drew什么? 将原句一个完整的过程拆开是不对的, 这个思想是很重要的, OG256C就是这个道理, 不能把原来的完整意思拆开说.

　　53. adj.+N and/or +N, adj管两个, 可能存在可数与否的修饰问题, OG107B.

　　54. 副词应该放在要修饰的形容词前面, 否则awkward and vague, 而且这种说法不如用名词结构好, OG73C.

　　55. 并列形式的平行(be, and, not only…but also)尽量保持时态的统一(OG246CDE, OG248C), 除非逻辑上面或者时间状语上面有明显的暗示.

　　56. 表语从句的that不可以省略.

　　57. 不可以be+because of, 用be+caused by, OG237C.

　　58. being单独出现强调正在进行, 一般错误, 介词后面的being单说.

　　59. when/ while+N, 错误. 当状语从句中是系表结构的时候, 而表语这个时候有时一个名词,那么在英语的语法中是不能省略前面的主语和谓语的. 所以When he was a teacher, he lived in the school, 不能省略成when a teacher, he lived in the school. 当后面是形容词或者是介词短语的时候是可以省略的.
