高中英语语法非谓语动词

高中英语语法非谓语动词

非谓语动词动词在句子中除了充当谓语外,还可以起名词、形容词或副词的作用,在句子中充当主语、宾语、表语、补语、定语和状语。

这就是动词的非谓语形式。

当句子中需要用某种动作作主语、宾语或作某种修饰、说明的成分时,就要使用这种形式。

动词的非谓语形式有三种:(1)动词不定式:to study (to + 动词原形)(2)分词:studying (现在分词)、studied (过去分词)(3)动名词:studying (形式与现在分词相同)动词非谓语形式仍具有动词的一般特征,可以带有宾语、状语等构成短语。

动词非谓语形式有以下几种形式变化(以write为例):一、动词不定式其形式是“to+动词原形”。

to是不定式符号,无词义。

其否定式是在to前面加上not, never等否定词。

不定式可以有自己的逻辑主语,由for引出,加在不定式短语前面。

如果不定式的逻辑主语是表示不定式动作的承受者,则不定式用被动语态。

所谓逻辑主语,就是指非谓语动词等动作的执行者。

由于非谓语动词等带有动词的特征,但又不是谓语动词,所以这个动作的执行者就不能称为主语,而在逻辑上又是这个动作的执行者,所以就称为逻辑主语。

如果不定式逻辑上的主语是这个不定式所表示的动作的承受者,这个不定式一般要用被动语态。

疑问词(who, whom, whose, what, which, when, where, why, how还包括whether)等后面加不定式构成不定式短语,可做主语,表语,宾语等。

(一)作主语。

在不定式短语作主语的句子中,往往用it 作形式主语,而不把不定式短语放在句子的后面。

如:To die like that is a terrible thing.=It is a terrible thing to die like that.象那样死去是一件可怕的事。

(it 作形式主语,把真正的主语to die like that放在后面)To know oneself is difficult.=It’s difficult to know oneself.有自知之明不容易。

非谓语动词在句中充当除谓语以外的句子成分的动词形式叫做非谓语动词。

非谓语动词分为三种形式:不定式、动名词和分词(分词包括现在分词和过去分词)不定式一、不定式的作用1、作主语不定式作主语时,谓语用单数。

往往用it 作形式主语,把不定式放在谓语后面。

如:Ittookus two hoursto finish the job.It is impossible for usto get there on time.It is very kind ofyou to help us.注意:(1)其他系动词如look, appear等也可用于此句型。

(2)当不定式作主语的句子中又有一个不定式作表语时,不能用It is…to…的句型。

试比较:Itis tonegate my ownidea to believe him.(错)To believe himis to negatemyown idea .(对)(3)It is+ adj.of /for sb. todosth. 结构中,当不定式的逻辑主语和前面的形容词可以构成系表结构时,用of, 否则用for.2、作宾语(1)动词+不定式。

如:He managedto escape fromthe fire.I find it hard to getalongwithhim.(it 作形式宾语)注:下列动词通常用不定式作宾语:want,try, hope, wish,need, forget,know,promise, refuse, help, decide,begin,start,learn,agree,choose, get等(2)动词+疑问词+to , “特殊疑问句+不定式”相当于名词,作宾语。

如:I don’tknow what to do next/ howtodo it next.I can’tdecide whentogo there.注意:不定式短语作宾语时,如果还带有宾语补足语,往往把不定式短语放在宾语补足语之后,用it 作形式宾语。

如:I findit necessary tolearn a foreign language.3、作宾语补足语(1)动词+宾语+不定式(to do )。

如:He warnedmeto becareful.I want you to speak toTom.Whatmakes you think so?(不带to的不定式)注:可以用动词不定式做宾补的动词有:ask, tell, order ,want ,get, would like, like, advise,invite,allo w,help,wish,warn, expect, prefer,encourage(2)表见解、看法的动词结构可为:动词+宾语+to be 的不定式结构。

如:We consider Tom to be one of the best students in ourclass.The bookis believed to be useful.(被动语态)(3) There +不定式。

如:We didn’texpect there tobe so manypeople there.我们没料到会有那么多人在那里。

注意:(1)有些动词需用as短语作补语,像regard, think, believe,take,consider。

如:We regardTom asour bestteacher. 我们认为汤姆是我们最好的老师。

Marytook himasher father. 玛丽把他当作自己的父亲。

(2)在动词feel(一感),hear,listen to(二听),have,let, make(三让),notice,see, watch, observe, look at(五看)(即:吾看三室两厅一感觉)等后面的补足语中,不定式不带to,但变为被动语态后,必须带to。

如:Theysaw theboy fall off thetree. The boywasseen to fall off thetree.(3)help后面作宾语补足语的不定式可以带to,也可以不带to.I often help him(to)clean the room.I helpedhim (to) find histhings.4、作定语不定式作定语,修饰名词或代词,不定式和它所修饰的名词之间有逻辑上的主谓关系、动状关系、同位关系或动宾关系。

不定式通常要放在这些被修饰的词后。

如:I havea lot of workto do.(动宾关系)Heis looking for a roomto livein.(动状关系)He isthe firstpersonto think of the idea.(主谓关系)Hehas got achance to goabroad.(同位关系)注意:1.不定式的逻辑主语是句子的主语时,不定式用主动形式表被动。

如:Doyou haveanything elseto say?2.如果作定语的不定式是一个短语,则要保留不定时短语中的副词或介词。

如:I need a pen to write with .(I willwirte withthe pen ) (我需要一直钢笔写字)I have a littlebaby to lookafter.(I must look afterthe little baby )(我有一个婴儿要照看)作状语,表示目的、结果、原因等,有时还有一些固定搭配的不定式短语,如inorder to, so as to,so…asto,such…asto, ….enough to, too…to等。

(1)做目的状语,to, only to (仅仅为了),in order to, so as to, so(such)….asto…(如此···以便···)如:Heran sofastasto catchthe first bus. 他飞快地跑以便赶上第一班车。

He cametothe school to see his son.(2)作结果状语,表事先没有预料到的,要放在句子后面。

如:He hurried tothe post office only to findit wasclosed.Hesearchedthe room only tofind nothing.(3)做原因状语。

如:We were very excitedto hear the news.I’m glad to seeyou.(4)做条件状语。

如:Toturntothe left,youcould find a post office.5、作表语不定式可放在be动词后面,构成表语。

如:The question is how to put it into practice.My question is whento leave.His dreamis tobe a doctor.Herwork is to look after the babies.注意:1.不定式在句中作表语时,对应的谓语动词用单数。

2.当助于是不定式时,表语不能用Ving形式,可用不定式。

如:To see istobelieve. (眼见为实)6、独立结构。

如:To tell you the truth, I don’t agree withyou.Tomakematters worse, it beganto rain.二、不定式的时态和语态1、不定式的时态(1)现在时:有时与谓语动词表示的动作同时发生,有时发生在谓语动词的动作之后。

如:He seems to know this.I hope tosee you again.(2)完成时:表示的动作发生在谓语动词表示的动作之前。

如:I’m sorry to have givenyou somuch trouble.Heseemsto havecaughta cold.(3)进行时:表示动作正在进行,与谓语动词表示的动作同时发生。

如:He seems to be eating something.(4)完成进行时:表示动作从过去某个时间开始,一直延续到现在,并有可能持续下去。

如:She is known to havebeen working on the problemfor many years.2、不定式的语态当不定式的逻辑主语是其动作的承受者时,就用被动式。

如:He was seen toenter thehall. He asked to be sent towork in Tibet.三、省to 的动词不定式1、情态动词(除ought外,ought to)2、Wouldrather, had better.3、感官动词see, watch, look at,notice,observe,hear,listen to, smell, feel 等后作宾补,省略to.注意:在被动语态中to 不能省略掉。

如:I sawhimdance. He was seento dance.The boss made themwork thewhole night.Theywere madeto work thewholenight.4、使役动词let,have,make.5、由and,or 和than 连接的两个不定式,第二个to 可以省去。

如:Hewants to moveto France andmarry thegirl.6、Help可带to ,也可不带to, help sb.(to)do sth.7、Why…/Why not…8、But 和except 前是动词do时,后面出现的动词用不带to的动词不定式。

试比较:He wants to donothing butgoout.Hewants to believe anythingbutto take the medicine.9、通常在discover, imagine,suppose, think,understand 等词后,可以省去to be.如:He is supposed (to be) nice. 他应该是个好人。

——I usually go thereby train.——Why not ______by boat for a change?Ato try goingB trying togoCtotryand goD try goingPaul doesn’t have to be made ______. Healwaysworks hard.A learnB to learnC learnedD learning四、动词不定式的否定式。
