1、英语专业四级考试语法词汇知识讲座,语法词汇填空完形填空,语法词汇填空,1语法考题的涉及面宽，近年考题曾经考到：几乎所有词类；动词的三种非谓语形式；各种从句及关系词的用法；动词时态、虚拟语气、情态动词的用法；独立主格，主谓一致，倒装，强调、并列结构等基本语法知识。2语法考试的重点突出，语法考试的重点为内容庞杂较难掌握的项目，这些项目还反复出现，如：虚拟语气，状语从句，定语从句，独立主格，情态动词。3具体考查重点为以上项目中的特殊用法，不常用的情况,综观这近几年考题，可发现：,语法部分,would ratherthat从句一般过去时；It is vital necessary important
2、urgent imperative desirable advisable natural essentialthat动词原形；It is timeabout timehigh timethat一般过去时；proposalsuggestionthat动词原形；lestthatshould动词原形；if onlythatwould动词原形。,虚拟语气的考点为：,状语从句的考点为：,非if引导的条件状语从句，此类句子多用at times，provided，so long as，in case，once等来替代if；由even ifso，now that，forall等引导的让步状语从句；justh
3、ardly.when引导的时间状语从句；more than，as.as，not so much as，the same as，as much as等引导的比较状语从句。,独立主格结构多以逻辑主语分词的形式出现。情态动词多与完成时形式连用。定语从句重点考查介词关系代词（which）和as作为关系代词。动词时态常考完成时态，如现在完成时，现在完成进行时，过去完成时，过去完成进行时，将来完成时等。,词汇部分,专业四级考试的词汇部分要求考生能灵活正确运用教学大纲语法结构表一至四级的全部内容，熟练掌握教学大纲词汇表中一至四级规定的50006000个认知词汇及其最基本的搭配。其考查重点为：,1动词、名词与
4、介词的搭配如：popularpatientwith；yieldsolutionadapttransferaccessto；accuserequireof；chargefor；underdiscussion等等。2习惯用法如：confess toset aboutbe used todoing；be supposed tohavemake sbdo等。3由同一动词构成的短语如：come，go，set，break等构成的短语。4单个的动词，抽象名词，形容词和副词多以近义词、同义词的形式出现5介词短语在句中作状语如：in terms of；with the exception of；in vain等
5、，另外还应注意rather than，other than，such as，nonenothingbut等词在考题中的出现。,语法和词汇的复习思路：,1全面掌握基本语法点，重点记住各个项目中的“偏，特，难”点。2掌握常用习惯用法和词组。3注意在阅读中培养语感，因为在语篇层次上培养的语感往往可以直接帮助答题。4研究以往考试试题，适当做些练习记住典型题例。,Back,完型填空出题点,例一：1995年全真题中的第38题They quickly made use of the newer and faster means of communication to improve the(38)_ and

10、he song culture of a people in a fundamental form.(A)They occur where they are(B)Occuring where(C)Where they occur(D)Where do they occur 例2:_Indiana,is in a rich farming and dairy area,it is primarily a diversified industrial center(A)Fort Wayne(B)Although Fort Wayne(C)For wayne is in(D)Fort Wayne,i
11、n,C,B,填空题常考结构,例1：William Walkers mural,“Wall of Respect,”_an outdoor wall in Chicago,deals with social issues.(A)covers(B)covers it(C)which covers(D)which it covers 例2：In copper engravings and etchings,_caused by the edges of the plate is clearly visible on the paper.(A)the impression is(B)if the im
12、pression is(C)impressions(D)the impression,二、谓语动词专一原则任何一个句子只可能存在一个谓语动词。句子中不可能没有谓语动词，也不能多于一个谓语动词(除非中间存在连接词，构成主从复合句)。,C,D,填空题常考结构,三、平行结构技巧：如果填空题中空格的后面有and,或者and后面有空格，那么这道题目一定是考察平行结构。填空题中平行结构出现的形式是：A and B,A,B,and C例1：The technique of recording,classifying,and_is known as accounting.（A）an enterprises t
13、ransactions summary(B)the summarizing of an enterprises transactions(C)transactions of an enterprise are summarized(D)summarizing the transactions of an enterprise 例2：Louis T.Wright,a surgeon,developed ingenious orthopedic braces,_,and supervised the first use of Aureomycin on human patients.(A)trea
14、ting skull fractures that he pioneered in(B)pioneered in treating skull fractures(C)which pioneered in treating skull fractures(D)he was a pioneer in the treatment of skull fractures,D,B,填空题常考结构,四、宾语从句结构宾语从句的引导词在前面的主从复合句中已经提到。这里指出的是填空题中关于宾语从句考的最多的两个结构：state(陈述，表明)+that indicate(指明,表明)+that例1：The qua
15、ntum theory states _,such as light,is given off and absorbed in tiny definite units called quanta or photons.(A)energy that(B)that it is energy(C)it is energy(D)that energy 例2：Studies of the gravity field of the Earth indicate_yield when unusual weight is placed on them.(A)although its crust and man
16、tle(B)its crust and mantle to(C)that its crust and mantle(D)for its crust and mantle to,D,C,填空题常考结构,五、介词+which结构许多同学在选择which还是介词+which上总是不太明白，这里有一个技巧可以告诉大家。“which”后面一定加一个缺主语或者宾语的句子，因为“which”在这个句子中作了宾语或者主语成分。“介词+which”后面则跟一个完整的句子，因为”介词+which”整个结构在定语从句中作状语。例1：In the United States,a primary election is
17、 a method _voters select the nominees for public office.(A)that(B)by which(C)is that(D)by those 例2:Croquet is a popular lawn game _ players hit wooden balls through wire arches called wickers.(A)when(B)which(C)is when(D)in which,B,D,填空题常考结构,六、in that结构在表示“原因”概念的引导词中，because of+名词，consequently是副词,而“i
18、n that”是原因状语的引导词。例1：Mercury differs from other industrial metals _ it is a liquid.(A)whereas(B)in that(C)because of(D)consequently 例2：Hovercraft,or air-cushion vehicles,are unusual _travel over land and water on a layer of air.(A)they(B)in they(C)that they(D)in that they 例3：Emily Dickinsons garden w
19、as a place_great inspiration for her poems.(A)that she drew(B)by drawing her(C)from which she drew(D)drawn from which,B,D,C,填空题常考结构,七、what 结构 记住一点：what=the thing that例1：The chief foods eaten in any country depend largely on_best in its climate and soil.(A)it grows(B)what grows(C)does it grow(D)what
20、does it grow 例2：During the eighteenth century,Little Turtle was chief of the Miami tribe whose territory became_is now Indiana and Ohio.(A)there(B)where(C)that(D)what,B,D,填空题常考结构,八、同位语结构同位语考试形式一：名词作主语，主语同位语,_(注意是两个逗号)例1：The tongue,_,is an important aid in chewing and swallowing.(A)is the chief organ
21、 of taste(B)tasting the organ chiefly(C)the chief organ of taste(D)the organ chiefly tastes,C,填空题常考结构,同位语考试形式二：名词作主语，前面的名词是主语同位语，解释说明后面的名词：同位语,_(注意是一个逗号)例2：A prolific writer of prose and verse,_ of Native Americans in her novel,Century of Dishonor.A)Helen Hunt Jackson took up the cause(B)the cause t
22、aken up by Helen Hunt Jackson(C)was Helen Hunt Jacksons cause(D)the cause that Helen Hunt Jackson took up.例3：Often very annoying weeds,_ and act as hosts to many insect pests.(A)that crowd out less hardy plants than goldenrods(B)crowding out less hardy plants by goldenrods(C)the goldenrods crowding
23、out of less hardy plants(D)goldenrods crowd out less hardy plants,A,D,填空题常考结构,同位语考试形式三：主谓宾后面出现一个名词，那么名词可以作宾语或者表语的同位语例4：An Olympic marathon is 26 miles and 385 yards,approximately_from Marathon to Athens.(A)the distance is(B)that the distance is(C)is that the distance(D)the distance,D,填空题常考结构,九、比较结构比
24、较结构中要注意两点：1、倒装性；2、对称性例1：Western Nebraska generally receives less snow than_eastern Nebraska.(A)does(B)in(C)it does in(D)in it does 例2:Hot objects emit_do cold objects.(A)rays more than infrared(B)rays are more infrared than(C)more than infrared rays(D)more infrared rays than,A,D,填空题常考结构,比较结构中还需要注意相互
25、比较的必须属于同一种事物例例3：The activities of the international marketing researcher are frequently much broader than_.(A)the domestic marketer has(B)the domestic marketer does(C)those of the domestic marketer(D)that which has the domestic marketer 例4：The annual worth of Utahs manufacturing is greater than_.(A)
26、that of its mining and farming combined(B)mining and farming combination(C)that mining and farming combined(D)of its combination mining and farming,C,A,填空题常考结构,十、定语从句省略结构关系代词在定语从句中做宾语时可以省略例1：Most crocodiles will eat anything_capture and overpower.(A)can(B)they can(C)which can(D)and 例2：A majority of
27、people in the United States can get all the calcium their bodies_from the food they eat.(A)require(B)requires(C)requiring(D)to require,B,A,填空题常考结构,十一、状语从句省略结构 Metals expand when they are heated.Metals expand 是主句；when they are heated 是状语从句。但是这个状语从句中可以省略掉they are,句子变成：Metals expand when heated.但是并不是所有
28、的状语从句都可以这么省略。这种省略从句主语的方式理论上需要满足以下两个条件：第一、从句主语和主句主语必须保持一致；第二、从句的谓语必须是be动词，主语和be动词同进同出，比如上面的they和are要么同时省略，要么同时保留。For example:,填空题常考结构,例1：Although_rigid,bones exhibit a degree of elasticity that enables the skeleton to withstand considerable impact.(A)apparently(B)are apparently(C)apparently their(D)a
29、re they apparently 例2：All marble is composed of crystals of the minerals，calcite or dolomite,_,are perfectly white.(A)when,pure which(B)when,which pure(C)which,pure when(D)which,when pure例3：_relatively costly,the diesel engine is highly efficient and needs servicing（维修）infrequently(A)Even(B)It is(C)
30、Even though(D)There is,A,D,C,填空题常考结构,十二、动词ing+名词的复数 作主语结构这是一个比较难的结构，因为许多同学经常混淆动名词和现在分词。现在分词相当于形容词，和后面的名词是修饰与被修饰的关系；动名词是相当于具有动词特征的名词，和后面的名词是动宾关系。那么如何在句子中判断动名词和现在分词呢？我们来看两个例子：Doing exercises is a good habit.做练习是一个好习惯。The starving troops have to surrender.第一个句子强调的是做，而不是练习，不能说练习是一个好习惯，只能说做练习是一个好习惯，因此do是
31、中心词，它和后面的名词是动宾关系，那么这个do就是动名词；第二个句子说挨饿的军队必须投降，是军队投降，而不是挨饿要投降，因此中心词是troop，starving是来修饰troop的，因此starving是现在分词。在“动词ing+名词的复数”作主语结构的句子中，谓语动词用单数：is/wasFor example:,填空题常考结构,例1：_by transferring the blame to others is often called scapegoating.(A)Eliminate problems(B)The eliminated problems（被消除的问题）(C)Elimina
32、ting problems(D)Problems are eliminated 例2：_wooden buildings helps to protect them from damage due to weather.(A)Painting(B)Painted(C)The paint(D)By painting 例3：Scientists think _helps some tree to conserve water in the winter.(A)when losing leaves(B)leaves are lost(C)that losing leaves(D)the leaves
33、 losing,C,A,C,填空题常考结构,十三、make结构 make结构即为：make+sth.(宾语)+possible+（宾语补足语）共有三种形式：make it possible+to do make it possible+that引导的从句make possible sth(这个sth一定很长，它后面有一个后置定语)做题技巧：如果possible后面有to do 或者that引导的定语从句,中间一定有it 如果possible后面有名词，中间一定没有it例1：X-rays are able to pass through objects and thus make_details
34、 that are otherwise impossible to observe.(A)it visible(B)visibly(C)visible(D)they are visible例2：Using many symbols makes_to put a large amount of information on a single map.(A)possible(B)it possible(C)it is possible(D)that possible,C,B,填空题常考结构,十四、the more the more结构这个结构的意思是“越.越”，结构一共有三条规则：1.the mo
35、re后面的名词必须使用冠词或者所有格,新题专门考这条规则 2.the more 后面的谓语如果是be动词的话，可以省略.3.第二个the more 后面可以使用倒装，而第一个后面却不行。the more，the more其实是原因状语从句，前面是原因，后面是结果，倒装句中必须是主句倒装，从句绝对不能够倒装。例1：The stronger_ magnet,the greater the number of lines of magnetic force.(A)of(B)the(C)is the(D)is of the例2：The less the surface of the ground yi
36、elds to the weight of the body of a runner,_ to the body.(A)the stress it is greater(B)greater is the stress(C)greater stress is(D)the greater the stress,B,D,填空题常考结构,十五、表示结果的伴随状语结构主谓宾完整的句子后面，如果出现两个词，thereby或者thus,那么这两个词后面必须使用现在分词，表示“从而”的意思，这便是表示结果的伴随状语结构。但是必须注意并不是thus后面就是加doing，必须是前面一个完整的句子才对。例1：The
37、 Smithsonian Institution preserves more than sixty-five million items of scientific,historical,or artistic interest,_winning the popular title,“attic of the nation.”(A)however(B)thus(C)and(D)moreover例2：Snow aids farmers by keeping heat in the lower ground levels,thereby_from freezing.(A)to save the
38、seeds(B)saving the seeds(C)which saves the seeds(D)the seeds saved,B,B,填空题常考结构,十六、形容词最高级省略结构 The crane is the tallest bird of the wading birds.最高级后面的名词与范围名词重复，可以省略，句子变为:The crane is the tallest of the wading birds.例1：The crane is _ of the wading birds.(A)the tallest(B)the tallest that is(C)which is
39、the tallest(D)which the tallest is例2:Cows are said to be the least _ of domestic animals.A.intelligent B.intelligently C.the intelligentest,A,A,填空题常考结构,十七、规则动词过去分词作定语结构这里的规则动词指的是过去式和过去分词一样，导致考生看不出句子结构，比如：program,programmed,programmed 因此判断这个词是过去式还是过去分词就显得比较重要：第一步：从逻辑上判断这个动作是主动还是被动第二步：如果是被动的话，做谓语前面一定有
40、系动词be例1：_ Wupatki National Monument in Arizona features structures built of red sandstone by ancestors of the Hopi people.(A)That the(B)In the(C)Around the(D)The例2：Antibodies _ by small,round cells called lymphocytes and plasma cells.(A)to be made(B)making(C)made(D)are made例3：Automatons programmed t
41、o perform a given task _the flexibility and adaptability of human beings.(A)without(B)lack(C)minus(D)not having,D,D,B,填空题常考结构,十八、逻辑主语结构在一个完整的句子前面出现现在分词、过去分词、或者介词短语，那么这个句子的主语是前面这三种结构逻辑上的主语。例1：Having been served lunch,_.(A)the problem was discussed by the members of the committee(B)the committee membe
42、rs discussed the problem(C)it was discussed by the committee members the problem(D)a discussion of the problem was make by the members of the committee例2：_was not incorporated as a city until almost two centuries later,in 1834.(A)Settling Brooklyn,the Dutch(B)The Dutch settled Brooklyn(C)Brooklyn wa
43、s settled by the Dutch(D)Settled by the Dutch,Brooklyn,B,D,填空题常考结构,例3：At thirteen_at a district school near her home,and when she was fifteen,she saw her first article in print.(A)the first teaching position that Mary Jane Hawes had(B)the teaching position was Mary Jane Hawes first(C)when Mary Jane
44、Hawes had her first teaching position(D)Mary Jane Hawes had her first teaching position例4：Even at low levels,_.(A)the nervous system has produced detrimental effects by lead(B)leads detrimental effects are producing the nervous system(C)lead produces detrimental effects on the nervous system(D)the d
45、etrimental effects produced by lead on the nervous system例5：The chorus plays a large part in any oratorio,linking areas were sung by soloists with segments of choral music.,D,C,填空题常考结构,十九、复合宾语结构有些及物动词+宾语后意思表达不完整，需要再加形容词或者名词来补充说明宾语被叫做不完全及物动词，该形容词或者名词叫做宾语补足语。宾语加补足语叫做复合宾语。当宾语和宾补由主动语态变为被动语态，分别变为主语和主补。We
46、 played soccer.We called him Bob.Bob在这里作宾语补足语 He was called Bob.Bob在这里作主语补足语下面列出了一些经常要求使用宾补的动词:make,consider,call,elect,appoint,例：We appoint him monitor.We elected him president.例1：Poodles were once used as retrievers in duck hunting,but the American Kennel Club does not consider them_because they a
47、re now primarily kept as pets.(A)where sporting dogs(B)sporting dogs(C)when sporting dogs(D)they are sportingdogs,B,填空题常考结构,二十、It结构一、强调句型:It is+强调部分+that+其余部分这个句型需要注意几点：强调部分+其余部分是一个完整的句子；强调部分可以强调主语、宾语和状语，不能强调谓语和定语；强调人使用who或者that,其他的只能用that(即使是时间和地点)，who 和that绝对不能省略如果原句是过去时态，强调句型使用it was.，例如：原句：Ann b
48、ought these books last year.强调宾语：It was these books that Ann bought last year.强调状语：It was last year that Ann bought these books.二、形式主语 It is+名词/形容词+to do/that 引导的句子 to do/that 引导的句子是真正的主语，it 是形式主语，这是为了避免头重脚轻。例1：It is the interaction between people,rather than the events that occur in their lives,tha
49、t are the main focus of social psychology.例2：_an increasing international exchange of educational films.(A)It is(B)There is(C)Though there is(D)Although it is,is,B,填空题常考结构,二十一、which 引导的定语从句结构 which是关系代词，which后面应该加缺主语或者宾语的句子，在这个句子中，which要作成分，作主语或者宾语in which+完整的句子 which在定语从句中作in的宾语，所以不能作后面句子的主语名词+of w
50、hich+谓语动词 of which来修饰名词，名词在定语从句中作主语，所以后面直接跟谓语动词例1：In blank verse_of ten syllables,five of which are accented.(A)line consists of each(B)consists of each line(C)each line consists(D)it consists of each line例2：The spiral threads of spiders web have a sticky substance on them_insects.(A)traps(B)trap it
