1月29日GMAT语法机经整理.

　　GMAT语法机经对于很多对于GMAT语法颇感无力的考生来说是个不小的助力，虽然答案都是考生自己给出，但是参考价值也不小，为此澳际小编特收集整理1月29日GMAT语法机经整理，分享给大家，希望对大家有所帮助，文中观点仅供参考。

　　1.[版本1]狗主：语法。有一题考了not only but also

　　Having won…., 人名’s work continued praised by Film Company, like 21che de….

　　[版本2]狗主：我考了很多having done，至少三题都有having done的用法。我觉得比GWD都难，而且选项中都是不一样的，需要一个个看和排除，这个倒是当时还挺安慰，感觉答的不错，应该是难题。not so much as平行。

　　[版本3]狗主： Having done，having been done 用法 (考点：句子逻辑)

　　注解：Having done，having been done 用法

　　a，必错用法(谢谢tangzimo)：

　　having done和having been done都不是动名词结构，因此不能充当名词成分!

　　所以SC中，如果这两个结构做主语、宾语等，必错!

　　having been done做后置定语，必错!

　　having been done做后置定语，一般都要改成相应的done做过去分词，或者改成定语从句

　　having done和having been done用于“with独立主格”中必错!

　　指with+sb/sth+having done/having been done这种情况

　　b，PREP中正确的句子：

　　1.Having finally reached a tentative labor agreement with its company&aposs pilots, the airline&aposs board of directors must now determine how the airline can both increase profits and compete more fectively for customers than it did in the past.

　　2.Some patients who do not respond to therapies for depression may simply have received inadequate treatment, having, for example, been prescribed a drug at a dosage too low to be fective or having been taken off a drug too soon.

　　c，夸克的语法大全里面明确写出having done做限定性修饰是错误的：

　　The perfective aspect cannot usually be expressed in the nonfinite clause:

　　误:The man having won the race is my brother.

　　正:The man who has won the race is my brother.

　　也就是说.完成时的ing分词形式(having done)作为限制性的修饰是不可以的，但是可以作为非限制性的修饰。

　　参考练习：OG12th SC第21题

　　Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.

　　A. Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are (正解)

　　B. Neuroscientists, having amassed a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are

　　C. Neuroscientists amassing a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are

　　D. Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood,

　　E. Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,

　　A选项"having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood"，你可以把这个成分理解成状语，也可以理解为定语，修饰的都是Neuroscientists这个主体或这个主体发出的动作，只要你把having看做定语和状语时，句意理解起来是一样的，那么就没有歧义问题。

　　2.狗主残狗：语法第一道上来就是说什么什么---(破折号，开始划线)most什么什么in 1070什么什么Kyoto, Japan什么什么啊啊啊记不得了，然后还有破折号!等我再想想。

　　3.我記得有一個考了unlike的用法，不過unlike是放在句中的，前面有個when-clause~

　　注意：unlike/like前后连接的结构要对称平行，可接抽象和具体名词。

　　4.[版本1]狗主：

　　Over..miles..in..B某地方... there lives SSS people who.....

　　選項有 live, lives, there live, had live...還有忘了...

　　有考到兩次both, 不難, 選項很容易分辨both裡外是否parallel

　　解析：题目很明显考到了时态的问题。

　　[版本2] 狗主：Over 某地, live the N people that are known as the most isolated people in modern world.

　　选项有have lived, lives……这个我应该没错吧……遇到这么简单的题也可以看出楼主的语法有多挫了

　　[版本3] 狗主：SC有那道机经上的over eighteen 啥啥啥(是一个地方) there lives 啥啥啥(一个什么东西)，我觉得这是个倒装吧，就是一个什么东西live在一个什么地方，所以我选的和狗主的一样live。

　　5.狗主：1.考了which从句的用法，考了同位语。。。(啊啊啊!!好笼统。。。对不起人民群众啊)

　　Which从句的用法

　　①which引导非限定性定语从句，前面必须加逗号

　　②要绝对挨着要修饰的名词，不能指代前面整个句子

　　6.[版本1]狗主：遇到一题与prep原题类似的

　　前半句划线

　　原题：

　　Whereas the honeybee’s stinger is heavily barbed and cannot be retracted from the skin, because the yellow jacket has a comparatively smooth stinger, it is therore able to be pulled out and used again.

　　A. because the yellow jacket has a comparatively smooth stinger, it is therore able to be pulled out and used

　　B. the comparative smoothness of the yellow jacket’s stinger allows them to pull it out and then can therore use it

　　C. the yellow jacket’s stinger is comparatively smooth, and can therore be pulled out and used

　　D. in comparison, the yellow jacket’s stinger is smooth, and thus able to be pulled out and used

　　E. in comparison, the yellow jacket has a smooth stinger, thus allowing it to be pulled out and used

　　这题答案是

　　解析：但如果是前半句划线，估计也会考对比的问题。

　　注意Whereas表示对比，所以对比的是honeybee’s stinger和yellow jacket‘s stinger 而不是honeybees’ stinger和yellow jacket比。

　　如果后半句有in comparison，则有Whereas比错，因为语义重复

　　[版本2]狗主：答案是E 群里考过的说是这个月的原题

　　As the honeybee&aposs stinger is heavily barbed, staying where it is inserted, this results in the act of stinging causing the bee to sustain a fatal injury.

　　A.As the honeybee&aposs stinger is heavily barbed, staying where it is inserted, this results in the act of stinging causing

　　B.As the heavily barbed stinger of the honeybee stays where it is inserted, with the result that the act of stinging causes

　　C.The honeybee&aposs stinger, heavily barbed and staying where it is inserted, results in the fact that the act of stinging causes

　　D.The heavily barbed stinger of the honeybee stays where it is inserted, and results in the act of stinging causing

　　E.The honeybee&aposs stinger is heavily barbed and stays where it is inserted, with the result that the act of stinging causes

　　7.[版本1]狗主：有一题考believe 还是 believe in的

　　[版本2] 狗主：机经里面那个很残的believe in 和believe的，我忘了题干是什么，但是不只这个split,还有believe in那个选项后面是有that的，而believe没有，还有it指代的问题，不难，大家仔细看就好

　　believe 和 believe in：

　　注解：believe是相信，信以为真的意思。是及物动词，后面直接跟宾语。

　　believe in 信任，信仰的意思，经常跟宗教，理论和概念相搭配。Believe是不及物动词。

　　我估计考题应该不会这么简单，但是根据意思应该可以排除一些选项。

　　8.Permit/Allow for

　　如果单说permit和allow这两个词，用法很接近，permit/allow sb. to do sth. Permit/allow doing sth.

　　Permit也可以作名词，意为许可证，

　　但是allow for 是完全不同的意思, 是考虑到，体谅某人的意思。一般接名词和名词词组。

　　例: We should allow for every possible delay.

　　9.[版本1]狗主：语文估计是掉到低分库了，感觉不是很难。语法有考破折号，分号，没有遇到having done哎。

　　[版本2]狗主：Maple syrup, 可以这样制作: First, maple leaves are collected from 什么, and second 放锅里——boiling it too long and you will get maple sugar.

　　偶考的这个地方是个破折号

　　[版本3] 狗主： 有个——(扩折号)的题。全划线。关于唯一一个“——”的选项很像正确选项，但我不确定，其他选项表意上很奇怪。大家要是遇到这题细读下。

　　注意：

　　破折号在GMAT里的用法：用于插入语，解释说明(代替冒号或分号)，话语/语义的中断和转折，反讽。

　　Prep08 1-182

　　The organic food industry has organized a successful grassroots campaign—using Web sites, public meetings, and also mass mailings—that have convinced the Department of Agriculture to change the proposed federal regulations for organically grown food.

　　A. using Web sites, public meetings, and also mass mailings—that have convinced

　　B. using Web sites, public meetings, and mass mailings—that has convinced

　　C. by using Web sites, public meetings, and mass mailings—in convincing

　　D. by the use of Web sites, public meetings, as well as mass mailings—that convinced(B)

　　E. which used Web sites, public meetings, and mass mailings—in convincing

　　本题答案为B。结构The industry has organized a …campaign—using …—that has convinced … to

　　10.狗主：不过语法考到了such as 和破折号的用法，题目划线部分都很长很长。
