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 mu

11、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 只作以匕”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 alone单独的，惟一的ali

14、否符合原级比较及比较级的结构。如：Do you enjoy listening to records?I find records are often,or better than an actualperformance.Aas good as Bas good Cgood Dgood as在这里as good a s 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 arethose with l

15、ittle ambition.2）比较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 years marathon was half.A of last years Bthose of last yearsCof 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

16、 readers,more often than not,find the novels of dickens far more exciting thanThackera/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+as.as.,或倍数词+more.than.,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 thanauto

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 health wa

20、s 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 much.as.与其说.不如说.The chief reason for

24、群体内同类事物的比较，如：among the teachers,of the fourdresses.注 意:among.相当于one o f,不说among all.。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/anything else上述词是用业将比

25、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。ther,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 th e，如：a most interesting book,most expensive restaurants,要注意与“the+形容词最高级+o f+名词”的结构表示的最高级的区别，如：He spoke in the warmest of voicesThey have been most kind to meBaske

29、mposes.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.Aliving on one*s knees Blive on one*s kneesCon one*s knees Dto live on ones knees（答案为D）Despi

30、te the temporary difficulties,the manager prefers increasing the output todecreasing 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 should be written in a formal style in a personalstyle.Arather than Bother than Cbetter than Dle

31、ss than答案为AFor the new country to survive,for its people to enjoy prosperity,new economicpolicies will be required.A to name a few Blet alone Cnot to speak Dlefs say（答案为B）2）如果平行的两个成分在形式上是介词短语，而且介词相同，一般说来第二个介词不要省略。如：At times,more care goes into the composition of newspaper and magazineadvertisements

32、than into the writing of the features and editorials.（三）代词及其指代一致-.代词的指代1 .that的指代作用that指代不可数名词和单数可数名词（如是复数，用 those）,后面通常跟有修饰语，如出现在比较结构中的that of。如Conversation calls for a willingness to alternate the role of speaker with that oflistener,and it calls for occasional digestive pauses by both.这里 that 指代前

33、面的 theroleoNo 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 uncommon way.A that Bhe Cone Dthis答案为C3.d。的替代作用。d。代替动词，注意数和时态的变化。如：For him to be re-elected,what is essential

38、y4.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谓语在数上要一致。把握主谓一致问题，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：Bu
