1、白勇语法笔记整理白勇语法笔记整理：GMAT语法考试总论GMAT语法的最高原则：最有效的表达原句所陈述的合理意思及合理重心。withdraw from 从。撤出句子结构句子结构、1、句子组成：核心部分（主语核心词+谓语）+可抛弃部分（定语/定从、状语/状从、同位语和独立成分/插入语）。阅读句子时，可先抛弃可抛弃部分，把握其基本结构和核心意思。2、GMAT考试以主从句和并列句为主，并从语意上考查句子内部的逻辑关心，尤其是不同的逻辑关系不能相互颠倒、混淆或随意改变。3、不完整句子结构：缺主句，缺主语，缺谓语。what 从句不能缺少谓语4.、标点符号：1）逗号不连接两个或三个句子，修改方法：A 用分号

2、；B 用连词and; C 用逗号和连词；D 将一个句子变成短语或变成另一个句子的从句。2）主语，插入成分，谓语 3） 冒号后可以使用：一个句子、句子并列、词或短语并列。4）破折号可以引出：作补充说明的句子或短语、同位语、插入语、列举的事物。5、副词不能替代连词：then、also、therefore、however等副词在使用时都应该加上and！（do A and then do B; doing A and then doing B; suspect sb. of having done A and then of doing B) 第二节 名词性从句（主语从句、宾语从句、表语从句）主语从句

3、It be + adj.(likely, possible, evident, surprising, true) / -ed分词(estimated, expected, predicted, anticipated, required, proved, found, feared, assumed, admitted, noted, supposed, reported, suggested, decided, noticed) +thatIt + seem/happen/ appear+ that.It be + 名词词组（good news to sb. , a fearful dis

4、appointment to sb.,) + that.只能使用陈述语序带有主语从句的复合句中，主语从句作为一个整体，视为单数，谓语动词用第三人称单数主语从句可以并列3、习惯搭配：It may well (很可能) be that; It may be that.二、宾语从句（动词型宾语从句、介词型宾语从句）1、动词型宾语从句引导词that一般不能省略，省略算作性对性错误。2、介词后一般只能接疑问词引导的宾语从句，不可以接that引导的宾语从句。但有三个例外：but that、except that(=but that)、in that(=because)属于约定俗成的表示。3、宾语从句后面有

5、补语的情况下，通常用形式宾语it来代替。Eg：make it clear that4、陈述语序三、表语从句1. 两类：be+that / be+疑问词1、主语主句是reason时，表语从句要用that 引导，不可用because. reasons作主语时，表语要用名词短语并列(the most common reasons for.are 名词短语1，名词短语2 and 名词短语32、陈述语序（what is in question is whether an improvement in nutrition was the main reason for the decline of inf

6、ectious diseases before the late nineteenth century.）第三节 特殊结构强调结构It is/was not untilthat(直到。才。)If any做插入成分，强调名词短语，意为“如果有的话”Many+noun,if not most,verbEg: many minority people, if not most, would agree with her.4、asas,if not more so, Eg: The use of chemical pesticides in this country is as extensive a

7、s it was ten years ago, if not more so.二、1. So/such.that 中so短语和such短语位于句首时，主句需要部分倒装。2.否定词或短语位于句首时，引起部分倒装：never; no longer; rarely; hardly; few; little; not until3.全倒装结构：介词短语/-ing分词短语/-ed分词短语/形容词短语+be动词+主语（主语与前面的be动词主谓一致）三、as结构1、as作介词：表示:作为，以. 1) n.+as+n. 2) v. +as +n.(宾语补语） :v.(accept, classify, def

8、ine, describe, know, name, refer to, regard, speak of, state, take, think, view） 3) v. +as +n.（方式状语) 2、as做连词：（1）表示时间，“一就”，“随着” （2）表示原因 （3）表示“像”（GMAT中这种考得最多）： 三种句型结构：(just) as +主句；(just) as ,so+主句； (just) as , so too+主句（要部分倒装）偶尔作代词：指代简单句子。Eg：Indirect socialization also occurs, as when television show

9、s or films reinforce stereotyped images of woman and men.in as much as:既然；由于，因为in so far as:在的范围内三、同位语结构1. 同位结构起修饰语的作用，一般用于修饰名词或者名词短语2. 同位语位置：名词前或名词后，一般在修饰对象的后面1、同位语结构中名词的数可以与其修饰对象的数不一致。2、形式：1）名词性同位语，名词解释名词：n. ,n.; n., a/an +n. 或a/ an+n., n. ; the +n. +n. 2）抽象名词( theory/ evidence/ belief/ principle)

10、 + that 从句， that 从句对抽象名词进行具体化解释。 注意：具体化同位结构（表示整体含义） 与of 结构(表示所属关系）的区别2) 用一个概括性名词去概括前面的解释对象：短语/句子，a program/information/an effort/ a practice that.( 必须能“概括”，逻辑意思要符合生活事理和科技常识）3）n. , n. (重复所修饰的名词）+that 定从4) n. , one/ ones +that 定从五独立主格结构 1. 独立主格结构在句首或句尾， 表伴随原因，条件，状态等 2. 一般独立主格：n.+ n. ; n. +-ed/ -ing； n

11、. +介词短语； n.+形容词短语 3. With型独立主格：with+ n. + -ed/ -ing; with+n. +adj. ; with+n. +介词短语 4. Each 型独立主格：句子+复数名词结尾, each +介词短语/形容词短语/ -ed/ -ing四、省略结构1、省略结构要能够还原，且还原后语法上要求结构对应，逻辑关系正确。2、两个句子并列，第一个句子中含有be/become，第二个句子的be/become必须省略。 E.g. Once the economic and social usefulness of the motor car was demonstrated

12、 and its superiority to the horse proved,. (proved前省略了was)Be 动词或者being 常倾向于省略: Be known as being sth. （省去being); n. , being sth. （省去being )3、习惯性省略：as needed; as planned; as required; as scheduled; whenever necessary/needed/possible than ever/before/ever before/usual/expected/predicted/estimated/anti

13、cipated Consider sth.+n./adj. ; prove(省略to be)+adj.省略相同的主语、宾语、连系动词、助动词、情态动词： Have done.and done.; will do .and do.; must/ would/ should/ can/ could/ may do.and do. 五、否定结构 1、表示否定意义的短语：cannot .too; in the absence of ; no morethan(与一样不.)；no amount of(怎么也不)eg: .No amount of washing will remove these sta

14、ins.无论怎样也不会洗掉这些污迹补充： believe 的习惯搭配：believe +that ; believe sth. To be; believe sth. (错误:believe sth. That.) So too 后面必须加句子（使用倒装结构） 名词的否定形式： not A, but B; not A, but rather B; A, rather than B; A, not B One.another; each.the other; each other ; some.others. Permit sb. To do sth. （permit that从句永远错） 并列

15、句的省略：实意动词不省略 Hopefully 在口语中表示：充满希望的；人们希望的。在书面语中为保证意思单一性，一般不使用hopefully Except that +主谓结构 Also是副词，不起连词的作用 However much表达强烈的语气 Responsible 的正确用法: be responsible for sth. ; be responsible for doing sth. ; be responsible to sb. (be responsible to do 永远错） It 不能指代：介词短语；前面整个句子 it 可以向后指代：主语从句；不定式短语 Propose:

16、 sth.(物）propose +that (that从句不使用虚拟）； Sb. (人）propose+that（that必须使用虚拟语气）； Propose sb. To do (不能使用被动）； Propose doing sth. ; propose sth. Commission：委员会，（是人） Doubt：doubt 用肯定形式，可以由whether 或that引导宾语从句，如doubt whether./doubt that.; doubt 用否定形式，只能由that引导宾语从句，如do not doubt that. 动词sell可以用主动的形式表示被动的含义，如sth. Se

17、ll well. 但当表示什么东西卖多少钱时必须用被动语态sth. Be sold for 介词with 后面不跟完整主谓语 标准书面语中，无生命事物的所有格形式优先使用n. Of n. 结构，较少使用nouns.这一结构 With +n. +as +adj. (with meat as rare) 不能作为独立主格结构，因为as作为介词后面不能加形容词，应加名词 并列句主语相同，应该省略重复的主语。 Have looked and seem：seen前省略助动词have Whether or not表达不简洁，必须省略or not 表达“关于.”优先使用介词about/over, 不倾向于使

18、用concerning/with respect to 定冠词the应放在more than+数词+名词前面，不能放在more than后面 “比预期”的表达方式：than expected; than sb. Expected; than sb. Had expected. Than expected/ than predicted/ than estimated 例题： 5. While some propose to combat widespread illegal copying of computer programs by attempting to change peoples

19、 attitudes toward pirating, others by suggesting reducing software prices to decrease the incentive for pirating, and still others by calling for the prosecution of those who copy software illegally.

23、r weekends. C. Dozens of New Yorks small museums are devoted to local history or various ethnic groups, but there are Small museums与big museums是相反概念，one-of-a-kind museums 与 one-of-all-kinds museums也构成相反概念。 则dozens of New Yorks small museums 与many one-of-a-kind museums不是相反概念，则不能用转折连词but 连接例题26. The c

25、 preferred status over others in the use of a public resource, the courts, which in theory are available to all but in fact are unequally distributed between rich and poor. In the use of 在。方面; the courts 作为a public resource的同位语；ask的宾语从句使用陈述语序主谓一致定语从句中的主谓一致：名词1of名词2+that，先用逻辑关系判断出that引导的定语从句修饰名词1还是名词

26、2，再根据名词1或名词2来判定动词的单复数形式(only/but)one of+n.pl+that+v.(复数)定从修饰复数名词，谓语动词用复数。the (only) one of +n.pl+that+v.(单数)定从修饰the (only) one，谓语动词用单数。二、倒装结构中的主谓一致：1、在there be A and B 句型中，由靠近be 动词的A决定be 动词的数的形式1.在完全倒装中，谓语动词的形式有谓语动词后民的主语的形式决定。2、在部分倒装中，主语前面的助动词的形式有该主语的形式决定。三、主语从句作主语时的主谓一致：一般谓语动词用单数，但what、who引导的主语从句含有

27、复数意义时，谓语动词可以用复数形式。四、主谓一致的一般规则：1. 复数名词/复数代词+each+v,谓语动词用复数1、each of/one of/( one in/one out of:意为分之一) + n.pl + v.单数 every n.pl + v.复数 Two/three.in/out of+复数名词作主语，谓语动词用复数形式2. 物质名词（如equipment, stone, citrus, iron, milk, dioxin)作主语，谓语动词用单数2、数词+单位词复数+of+不可数n. + v.复数 e.g. From 1050 to 1350, several millio

Part of/ most of/ all of/ some of/ 分数或百分数of/ the rest of +n. 作主语时，谓语动词的数的形式由of后的名词决定5、a total of / an average of +n.

29、pl，谓语动词用复数； the average of +复数n. 谓语动词用单数6、不定式短语或-ing分词短语作主语，谓语动词用单数补充： 1) make sth. Sth. ; make sth.+adj. ; make it +adj. +to do.2) 在英语中三个类似的词表转折：while, whereas, where,三者的区别在于：where只能放在句首作状语表示转折含义（where，+主句），不能放在主句后面的从句前面（主句，+where.)因为where 可能作定语；while 和whereas可放句首，也可放主句后面的从句前面3) Estimated at后常用价格等数
