最新托福高分语法讲解精选集第一章名词正确区分可数名词与不可数名词、正确选择可数名词单复数、名词之前的限定词与名词数(单复数)之间的关系以及名词在句子中承担的成分是TOEFL中常考的内容第一节可数名词考点一单复数可数名词与不可数名词的典型区别在于前者有单数和复数两种形式。

TOEFL考试中经常在不可数名词后面加了s,变为复数形式,其实这是再考你辨别可数名词和不可数名词的能力。

TOEFL中还经常考可数名词是采用单数还是复数,这往往要通过句意或者其他的一些指示词来辨别。

例如:various colors(various是各种各样的,后面当然要用复数形式)下面我们会讲一下复数形式。

复数形式简而言之就是在单数词尾加-s,但实际上细分起来还有一些具体的规则:1.结尾是s,o,x,ch,sh的词,加-es,如:buses, tomatoes,faxes,matches,brushes2.结尾是“辅音字母+y”的词,去掉y加-ies,如: factory-factories3.结尾是f,fe的词,去掉f,fe加-ves,如:half-halves, knife-knives4.结尾是o,f的词也有一些加-s,如:photos,beliefs, chiefs(1)Flower have long been cultivated and bred for their beauty and their fragrance.A B C D答案:A应改为:Flowers解释:表泛指时,可数名词可用不定冠词加单数或直接用复数,因谓语是复数,故改为复数(2)Doctor are discovering that there is a strong psychological component to chronicA B C Dpain.应改为:Doctors解释:表泛指时,可数名词用冠词加单数或直接用复数,因谓语动词是复数,故名词也用复数考点二复数形式特例这部分主要考察学生对特殊复数形式的记忆,作为考题并不过多的出现,但是在题干中的出现率却非常高,因此熟悉下列一些词的复数形式有助于理解题意1.单复数词形相同如:people,fish,Chinese(某国人),aircraft,means, series,species,sheep,deer,aircraft等2.外来词保留了原来的复数形式,这一点需要重点掌握,如:basis-bases analysis-analyse s crisis-crisesmedium(媒体)-media datum(数据)-data curriculum(课程)-curricula larva(幼虫)-larvae criterion(标准)-criteria phenomenon(现象)-phenomena3.通常只以复数形式出现的词语,如:clothes trousers compasses(圆规)scales(天平)savings(储蓄), statistics(统计数据),headquarters(总部),4.复数形式有特殊意义的词语,如:goods(货物),manners(礼貌),troops(军队), authorities(当局)5不规则的名词复数child-children mouse-mice louse-licetooth-teeth foot-feet6.注意:有一些结尾是-s的词,但是要当作单数看待,如:physics,politics,mathematics是表示学科的不可数名词例题:(1)With the incorporation of jazz history into current academic curricula,leadingA B Cjazz musicians are now founding on the faculties of several universities.D(2)Like some other running birds,the sanderling lacks a back toe and has a three-toedA B Cfeet.D答案:D应改为:foot解释:feet是foot的复数形式,不定冠词a之后应接可数名词的单数,故将feet改为单数词汇:sanderling:三趾滨鹬第二节限定词名词究竟要用单数还是复数,与名词之前的限定词有很大关系,限定词通常分如下几类:1.之后肯定接单数:a/an,every,one,another,each,either,this,that,such a,many a,etc.例句:Each of them has two books.You can read either book.(两本书你可以随便读一本)2.之后肯定接复数:these,those,many,such,other,大于one的数词(ten,hundred,thousand,million…), a few/few/fewer/fewest,a(great/good/large /small)number of,severalone of,all(of),some/any(of),most(of),a lot of,lots of,the rest of,plenty of3.之后既可接单数又可接复数:the,no,his,her,their, my,etc注意:这几类词大多不能同时使用考点一否定限定词no(1)no既可用于可数名词复数前又可用于单数前,表示否定意义.例如:No flowers in the garden.花园里没有花.No one is here.(2)no与否定副词not的区别是改错题的常见考点。

考点四 the more…,the more… 此句式常表⽰“越……越……”,more在此处泛指⽐较级,此句式的特点是前后两句以逗号隔开,句⼦结构平⾏,⽽且谓语动词⼀致时,为避免重复常进⾏省略, 如:The more she slept, the less comfortable she felt. The greater the size, the easier it is for you to spot. 填空题中常需填⼊两个分句之⼀,因此看到the more结构,要注意选与其结构相近的另⼀半the more句式 例题: (1) The greater the population there is in a locality, ----for water, transportation, and disposal of refuse.

第⼆节物主代词 物主代词⽤来表⽰所属关系,分为形容词性和名词性两类 ⼀、形容词性物主代词 形容词性物主代词分别是: 第⼀⼈称:my, our(复数) 第⼆⼈称:your(单复同) 第三⼈称:his, her, its, their(复数) 形容词性物主代词不能单独使⽤,只能作名词的限定词,如:my watch, their coach 改错题经常误⽤其他类型的代词作名词定语,此时应改为形容词性物主代词 例题: (1) Mammals lose body heat to them environment in cold weather more quickly than in hot weather. 应改为: their 解释: ⼈称代词them不能修饰名词, 与其对应的物主代词their恰好作名词environment的限定词 ⼆、名词性物主代词 名词性物主代词分别是: 第⼀⼈称:mine, ours(复数,我的东西,我们的东西) 第⼆⼈称:yours(单复同, 你的东西) 第三⼈称:his, hers, its, theirs(复数,它的东西,他们的东西) 名词性物主代词相当于名词可单独使⽤作句⼦的主语、表语或宾语。

托福测试辅导:语法讲解(13)考点二(not) so /as…as比较级特殊句式(not)so/as…as 表示“如同……一样、不如……”等意思,其结构和than句式相仿,但as…as 之间的形容词必须用原形,而且as…as必须搭配使用,如:It is as good as it looks.The boss is not so bad-tempered as you have described.填空题中常给出句子的一部分(第一个as),要求填出相搭配的部分(第二个as),一定要形成对这种搭配句式的敏感。

例题:(1)The best way to control rats is by seeing that they have as ----.(A) possibly little nourishment(B) nourishment possibly little(C) little as possible nourishment(D) little nourishment as possible答案:D解释:空格处需要动词have的宾语,同时包含as…as 句式,A、B都缺少与as搭配的结构,C语序有误,均可排除。

D中as…as possible, 为固定用法, 意为“尽可能”.(2)There is evidence that prehistoric humans used fire ---- 400,000 B.C.(A) so early(B) the earliest(C) as early as(D) so early that答案:C解释:依句意空格处需要“早在”这一意思的正确表达,只有C符合题意,用的是比较级特殊句式as...as 考点三the same…as此句式也常用来表示“和……一样”,the same和as既可连用,也可分开使用,如:She looks just the same as before.I got the same feeling as you did.改错题中常将此句式误用为the same…li ke /than, 要练就一双火眼金睛将其识别出来例题:(1)Meadowlarks are about the same size than robins, but they have heavier bodies, shorter tails, and longer bills.应改为:as.解释:the same as是固定搭配, 表示“与...一样”(2)Due to sophisticated transportation networks, people can now buy the same types of perishable goods in Toronto like in New York City.应改为:as解释:与the same相搭配的只有as, like不行。
