1、考研英语语法归纳从2002年起，研究生英语考试取消了语法、词汇等基础知识的考查，将此部分改考为听力。但取消了此部分知识点的考查并不意味着英语语法等基础知识的不重要。根据以往英语取得高分同学的经验和海文英语辅导名师的建议，他们都一致认为英语语法和词汇是学好、考好英语的重要基础，其实完形填空是对语法、词汇的综合考查，但更关键的是学好此部分有助于对英语句子结构的分析和理解，有助于学生掌握灵活多变的句式，这样不仅有助于学生做好阅读理解，而且有助于学生做好英译汉，写好作文。（）情态动词-.情态动词的现在完成式的用法情态动词现在完成式主要有两个功能：表示已经发生的情况和表示虚拟语气。在这两个方面 must

2、/mustnt.jcan/canntineed/needntimay/mayntjmight/mightntjshould/shouldnt;ougtht等情态动词+完成式表示的意思是有一定区别的1.表示已经发生的情况。1） must have+过去分词，表示对已发生情况的肯定推测，译为“（昨天）一定0如：My pain apparent the moment I walked into the room, for the first man I met asked sympathetically: Are you feeling all right?A must be B had been

6、d everything ahead carefully.我本来应该事先认真地把每件事情规划的很好，但实际上作者还是没有规划好，以至工作没有完成。3) ought to have +过去分词，表示动作按理该发生了，但实际上未发生，译为“该”,与should的完成式含义类似。如：T he porter ought to have called the fire-brigade as soon as he saw the fire in the stock, which went up in smoke .4) could have +过去分词，表示过去本来可以做但却未做，译为“完全可以这点与ou

7、ght/should/have +过去分词用法相似。如：What you said is right, but you could have phrased it more tactfully.5) may/might have +过去分词，表示过去可以做但实际未做译为那样也许会如：It might have been better to include more punchy statistics and photos of equipment in the introduction to further assist first-time office automation manager

8、s.-.几个情态动词常考的句型：1) . may/might (just) as well 不妨，最好”，与 had better 相近;Since the flight was cancelled, you might as well go by train.既然航班已经取消了，你不妨乘火车吧。相当于you had better go by train。2) .cannot/canttoo越越好,怎么也不过分”。注意这个句型的变体 cannot.over.:You cannot be too careful when you drive a car.驾车时候，越小心越好。The final

11、有的以“ly结尾的词是形容词而不是副词，这点要注意；形容词一般可以在句子中做定语，表语等成份，但有些形容词在句子中只能做表语和只能做前置定语;这些形容词在修饰时候有一定的特殊性要引起大家的注意，下面做了一下归纳：1以-ly结尾的是形容词而不是副词：costly昂贵的lonely孤独的deadly死一般的lively活泼的friendly友好的silly傻气的kindly热心肠的likely可能的leisurely悠闲的ugly长得丑的brotherly兄弟般的monthly每月的earthly尘世的2只作以七”开头的很多形容词只能做表语：afraid害怕的alike相象的awake醒着的alo

14、 enjoy listening to records? I find records are often , or better than an actual performance.Aas good as Bas good Cgood Dgood as在这里as good as比较连词与better than比较连词同时出现时候，不能省略任何一个介词。答案为AOn the whole, ambitious students are more likely to succeed in their studies than are those with little ambition.2）比较

15、的成分是否属于同类事物或同类概念，既是说比较要具有可比性。如：The number of registered participants in this year,s marathon was half.A of last years Bthose of last year*sCof those of last year D that of last years（前后相比的应该是今年和去年注册参加的人数“the number of故代替它的应该是单数指示代词“that”，而不能选择B , those是指代participants ,不是同类对比，答案为D。Young readers, more

16、 often than not, find the novels of dickens far more exciting than Thackera/s.3）比较级与倍数词关系及其位置原级结构中可插入表达倍数的词，表示为“为.若干倍”，当与有表示倍数比较的词在一起时候等，他们的位置是，倍数词+asas，或倍数词+morethan，但again 一般放在原级词之后，即“as+原级+ again+as”.如：Smoking is so harmful to personal health that it kills people each year than automobile acciden

17、ts.A seven more times B seven times moreC over seven times D seven times（答案为B）“Do you regret paying five hundred dollars for the painting?m*No, I would gladly have paid for it.nA twice so much B twice as muchC as much twice D so much twice（答案为B）My uncle is as old again as I am4）下列词和短语不用比较级形式却表示比较概念：

19、 a letter to his daughter.（1986年考研题）5）“比较级+ and +比较级”或“more and more/less and less +原级”以及“ever, steadily, daily等副词+比较级”结构表示“越来越”的意思，与这类结构搭配的常用动词有grow, get.become等。前面两种情况更多地出现在进行时态中，注意的是这三种情况引导的比较级后面都不需要用than.如：Things are getting worse and worse.As I spoke to him he became less and less angry.Her hea

20、lth was becoming daily worseThe road got ever worse until there was no road at all = the road got worse and worse.6)比较级前面可以用even, still, yet ,all the (more)等修饰语用以加强语气，表示“更加”的意思。如Today it is even colder than yesterdayI have yet more exciting news for you7)有关比较级的特殊句型：A): not so muchas与其说不如说The chief r

24、 among用于在同一群体内同类事物的比较，如：among the teachers, of the four dresses.注意：among.相当于one of,不说among all.o这一点考生应与汉语表达区别开来如：all visible lights, red light has the longest and violet the shortest wavelength.A Among B Of CFor DTo 答案为B2）比较级形式表示最高级意义时，比较对象的范围应用：any other +单数名词the other +复数名词the othersanyone/anythin

25、g else上述词是用业将比较级结构转变成最高级意义的关键词语，切不可遗漏，尤其是other ,否则会造成逻辑混乱的错误。如不能说：John runs faster than anyone.注意与汉语表达的不同。3） most可以用来修饰形容词或副词，意思相当于very ,用法区分单复数，但不能用定冠词 the ,如：a most interesting book, most expensive restaurants ,要注意与“the +形容词最高级+ of+名词”的结构表示的最高级的区别，如：He spoke in the warmest of voicesThey have been

29、moment it is played and enjoys it almost as much as the composer at the moment he composes.大多数情况下平行结构都是具有一定的比较含义的，有的是递进对比not onlybut （also）;prefer.to.;ratherthan 有的是同类对比:and ;but ;or ;both. and.;either.or.; neither. nor平行结构测试时候注意以下几点：1 .注意比较结构中相比较的内容在语法形式上是否相同。如：It is better to die ones feet than .A

30、living on ones knees Blive on ones kneesCon ones knees Dto live on ones knees（答案为D）Despite the temporary difficulties, the manager prefers increasing the output to decreasing it.2 .其他具有并列或比较意义的短语也可引导平行结构。1) rather than, let alone虽不是并列连词，但在结构上连接两个语法形式相同的成分。如：We are taught that a business letter shoul

33、 of speaker with that of listener, and it calls for occasional digestive pauses11 by both.这里 that 指代前面的 the roleoNo bread eaten by men is so sweet as that earned by his own labor.2 . one的指代作用one指代带不定冠词的单数可数名词，复数为ones。the one指代带定冠词的单数可数名词。如：A good writer is who can express the commonplace in an uncom

34、mon way.A that Bhe Cone Dthis答案为C3 . do的替代作用。do代替动词，注意数和时态的变化。如：For him to be re-elected, what is essential is not that his policy works , but that the public believe that it does.二.代词指代一致问题代词指代一致是指指代的名词在性、数、格上是否一致，或者所照应的名词词组在某些方面保持一致。Each cigarette a person smokes does some harm, and eventually he

35、may get a serious disease form its effect.这里he指代前面的person0It was during the 1920*s that the friendship between the two American writers Hemingway and Fitzgerald reached its highest point.这里its指代前面的两人的friendshipoOur department was monitored by two supervisors, Bill and me.这里me必须用宾格形式。代词指代一致必须注意以下几个原则

36、和规律：1 .邻近和靠近原则由either. or, neither.nor, not only.but (also)连接先行词时候，如果两个先行词在数和性上保持一致，就用其相应的一直的人称代词；如果两个先行词在数或性上不一致，人称代词一般与邻近的先行词在数和性上保持一致。Neither Mary nor Alice has her key with her.Neither the package nor the letters have reached their destinationIf either David or Janet comes , he or she will want

37、a drink2 .当 each, everyone, everybody, no one ,none .anybody, someone, somebody 用作主语或主语的限定词时候，或者anything, nothing, something everything等不定代词作主语时候，其相应的代词一般按照语法一致原则，采取单数形式。如：Everybody talked at the top of his voice.None of the boys can do it, can he?Everything is ready, isnt it”3 .当主语为复数形式，后跟each作同位语时

38、，如果each位于动词之前，其后的代词或相应的限定词用复数形式；如果each位于动词之后，其后的代词或相应的限定词用单数形式。如：They each have two coatswe are each responsible for his own family4 .由and连接两个先行词，代词用复数如：the tourist and businessmen lost their luggage in the accident(三)主谓一致问题主谓一致是指主语与渭语在数上要一致。把握主渭一致问题，考生主要解决的是对不同结构的主语单复数的认定，进而选择适当的谓语。解决主谓一致主要遵循三个原则：语

39、法一致原则意义一致原则就近一致原则很多情况下应该综合利用这三个原则来处理主谓一致，在不同情况下可能应用三个原则中的不同原则，具体应用哪种原则应该视具体情况而定。总结如下：-.谓语动词用单数的情况1 .动名词短语、不定式短语、名词性从句做主语，谓语用单数。如：Buying clothes is often a time-consuming job because those clothes that a person likes are rarely the cones that fit him or her.（1987年考研题）To understand the situation compl

43、语用复数情况1 .由and, both .and,连接的并列主语，和both ,a few, many .several等修饰语后面谓语动词通常用复数形式。Few people know he and I were classmates when we were at college.2 .集体名词police, public, militia, cattle ,class ,youth后常用复数形式的动词The Chinese people are brave and hardworkingThe cattle are grazing in the sunshine3 .当表示民族的词与冠词

45、; neither.nor.; whether. or.;not only.but (also);or 等连接的并列主语Neither money nor fame has influence on meNot only you but also he is wrong2)在倒装结构中，谓语动词与后面的第一个主语一致Blocking the open-sided porch, framed by the enveloping fog, stands a tall grave-faced policeman.Just outside the ruins is a magnificent buil
