高中英语高考复习非谓语动词知识讲解
高考英语非谓语动词知识讲解一、概念非谓语动词,又叫非限定动词,非谓语动词是指在句子中不是谓语的动词,主要包括不定式、动名词和分词(现在分词和过去分词),即动词的非谓语形式。
非谓语动词除了不能独立作谓语外,可以承担句子的其他成分。
从这个定义来看,简单来说,非谓语动词就是不是谓语的动词。
这听起来像是废话,但是我们必须有明确什么是谓语动词,在前面,我们已经说清楚了。
句子只能有一个谓语动词,那么其余的动词都是非谓语动词。
谓语动词就好比皇帝,非谓语动词,就相当于他身边的奴才。
这么一说,我们就很好理解了。
一般来说,非谓语动词通常有以下三种形式:二、三种形式(一)动名词(doing)动名词指的是动词ing形式的一种,兼有动词和名词特征的非限定动词(即非谓语动词)。
它可以支配宾语,也能被副词修饰,动名词有时态和语态的变化。
动名词具有名词的性质,因此在句中可以充当主语、表语、宾语、定语,但是不能充当状语。
从上面的定义中,我们可以很清楚知道动名词,顾名思义就是兼有动词和名词两种词性的作用。
在小学和中学的课程中,我们学习动名词做主语这个语法现象比较普遍。
大部分人也是从这个时候开始知道有动名词这个概念。
那么动名词究竟是动词,还是名词?前面已经说过,它是非谓语动词的一种形式,只不过他有动词和名词两种词性的作用。
故它是动词。
那么他竟然是动词自然有动词的性质,而且它可以充当名词有名词的作用,那么名词的作用,它也都有,它可以在句子中充当主语、表语、宾语和定语。
也就是名词能干的事,它也能干。
(二)不定式(to do)动词不定式,为非谓语动词。
在英语语法中,动词不定式是指动词中的一种不带词形变化从而不指示人称、数量、时态的一种形式。
它之所以被称做不定式,是因为动词不被限定,或者说不被词性变化所局限。
不定式属于非谓语动词形式。
根据国外和国内语法学家的研究,所谓不定式,其作用就是相当于情态动词加动词原形的形式。
为什么要这样说呢?因为他们都有相同的特征,以下:第一,原形can/may/could/would do sth.= to do sth.第二,都可表示不确定语气。

高考英语 第八章 非谓语动词知识精讲
非谓语动词[知识精讲]非谓语动词是高中英语语法中的一个重点和难点之一。
主要的考察形式为单项选择,在历年各地高考题目中广泛出现。
高中阶段,我们学习的非谓语动词内容包括不定式、动名词和分词的用法以及非谓语动词的复合结构用法。
一、概念和基本知识:什么是非谓语动词?首先,我们要了解英语中基本的句子结构:主语→ 谓语→宾语(+补语)↑ ↑ ↑定语状语定语我们知道主语和宾语分别是一个动作的发出者和接受者,他们具有名词的性质(即使主语或宾语是一个短语或者从句,也可以把它整体看作一个名词。
这种思维方法很重要,相当于数学当中的整体思想)。
谓语表示一个动作或一种存在的状态,具有一般的动词的性质。
定语是对主语和宾语起修饰、限定作用的成分,往往具有形容词的性质。
状语是对谓语动词在时间、地点、方式、目的、程度等方面进行修饰的成分,一般具有副词的性质。
由上我们可以知道,一般来说,动词都是放在谓语的位置上的,但是在具体的语境之中,为了使意思表达连贯完整,我们往往要借用动词来充当句子当中的其它成分。
这个时候,我们的动词就不能够再以动词本身的面貌出现在句子中,而是通过变化变成了不定式、动名词和分词等等形式。
有了恰当的形式,这些动词就可以在句子当中充当除了谓语以外的其它成分。
这就是我们所说的非谓语动词。
二、非谓语动词的基本性质非谓语动词既然不出现在谓语的位置,那么他们在句子中也就不具有动词的性质,而是具有诸如名词、形容词和副词等等的词性。
一个完整的简单句子里面,只能有一套主谓宾的结构。
也就是说,如果一个句子里面已经有了一个谓语动词,就不可能再有另外的谓语动词出现了。
(以上不包括用but、and连接和从句的情况。
)注意:不定式和分词一般是与其它词连接形成短语之后才具有了形容词、副词的性质。
我们平常说的“××短语作定语”、“××短语作状语”指的就是这种情况。
例如:To marry her,he has to earn a lot of money.中“To marry her”这个短语作为一个整体来作目的状语。
超详细非谓语动词讲解精编版
非谓语动词(the Non-Finite Verbs)定义在句子中不是谓语的动词,形式:不定式、动名词和分词(现在分词和过去分词)作用:在句子中充当主语、宾语、状语等。
特点:1.非谓语动词可以有名词作用(如动词不定式和动名词),在句中做主语、宾语、表语。
2.非谓语动词可以有形容词作用(如动词不定式和分词),在句中做定语、表语或宾语补足语。
3.非谓语动词可以有副词作用(如动词不定式和分词),在句中作状语。
4.谓语动词在句中作谓语,受主语的人称和数的限制;非谓语动词在句中不能单独作谓语,它不受主语的人称和数的限制。
5.英语中不能单独做句子的谓语。
与谓语动词的关系相同点(1)如果是及物动词都可与宾语连用,例如:They built a garden. They suggested building a garden.(2)都可以被状语修饰:The suit fits him very well. The suit used to fit him very well.(3)都有主动与被动, “体”式(一般式;进行式;完成式)的变化。
例如:He was punished by his parents.(谓语动词被动语态)He avoided being punished by his parents.(动名词的被动式)We have written the composition.(谓语动词的完成时)Having written the composition, we handed it in.(现在分词的完成式)(4)都可以有逻辑主语They started the work at once.(谓语动词的逻辑主语)The boss ordered them to start the work.(动词不定式的逻辑主语)We are League members.(谓语动词的主语)We being League member, the work was well done. (现在分词的逻辑主语)不定式一、形式功能:动词不定式:(to)+do,具有名词、形容词、副词的特征。

辨析几类情况:
一、不定式与动名词做主语:
1. 动名词做主语往往表示泛指的、一般的行为; 不定式 做主语常表示某次具体的行为或将来的动作。 e.g. Climbing mountains is great fun. 爬山很有趣。 To visit China is my next goal. 2. 不定式做主语,一般用it当形式主语,把作主语的不 定式短语后置。 e.g. It took me only five minutes to finish the job. 3. 动名词作主语有时用it作形式主语,把动名词置于句 尾。常见于以下句型中: It’s use/ good / fun… It’s useful/ nice/ useless… e.g It’s nice seeing you again.
情态动词/助 动词+ v.

高中英语2024届高考考点讲解与练习(非谓语动词作定语+非谓语动词作状语+非谓语动词作宾语补足语)
高考英语语法考点讲解与练习一、非谓语动词作定语【知识要点】1、非谓语动词包括四种:-to do不定式,-ing分词,-ed分词和动名词。
(重点为前三种)2、非谓语动词的词性及句法功能①-to do不定式相当于名词、形容词和副词,可以在句子中充当主语、宾语、表语、定语、状语和宾语补足语;②-ing分词相当于形容词和副词,可以在句子中充当表语、定语、状语和宾语补足语;③-ed分词相当于形容词和副词,可以在句子中充当表语、定语、状语和宾语补足语;④动名词相当于名词,可以在句子中充当主语、宾语、表语和定语。
3、前三种非谓语动词的形式与意义① -ing分词的基本意义为:主动或进行,变形有:进行式:doing被动式:being done完成式:having done完成被动式:having been done②-to do不定式的基本意义为:主动将来,变形有:进行式:to be doing被动式:to be done完成式:to have done完成被动式:to have been done③-ed分词表示被动或完成。
4、非谓语动词作定语由于三种非谓语动词都具有形容词的性质,所以它们都可以在句子中充当定语,并根据其在被修饰的名词中心词的前后位置,分为前置定语和后置定语两种。

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、动名词和现在分词都有时态和语态的变化.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:It took us two hours to finish the job.It is impossible for us to get there on time.It is very kind of you 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:It is to negate my own idea to believe him.(错)To believe him is to negate my own idea .(对)(3)It is+ adj. of / for sb. to do sth. 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 manage d to escape from the fire.I find it hard to get along with him.(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’t know what to do next/ how to do it next.I can’t decide when to go 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 find it necessary to learn a foreign language.3、作宾语补足语(1)动词+宾语+不定式(to do )。
如:He warn ed me to be careful.I want you to speak to Tom.What makes 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, allow, 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 our class.The book is believed to be useful.(被动语态)(3) There +不定式。
如:We didn’t expect there to be so many people 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r egard, think, believe, take, consider。
如:We regard Tom as our best teacher. 我们认为汤姆是我们最好的老师。
Mar y took him as her 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:They saw the boy fall off the tree.The boy was seen to fall off the tree.(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 helped him (to) find his things.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 have a lot of work to do.(动宾关系)He is looking for a room t o live in.(动状关系)He is the first person to think of the idea.(主谓关系)He has got a chance to go abroad.(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:Do you have anything else to 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 will wirte with the pen ) (我需要一直钢笔写字)I have a little baby to look after .(I must look after the 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in order to , so as to, so…as to, such …as to, ….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)….as to…(如此···以便···)如:He ran so fast as to catch the first bus. 他飞快地跑以便赶上第一班车。
He came to the 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 to the post office, only to find it was closed.He searched the room ,only to find nothing.(3)做原因状语。
如:We were very excited to hear the news.I’m glad to see you.(4)做条件状语。
如:To turn to the left , you could 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 when to leave.His dream is to be a doctor.Her work 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 is to believe. (眼见为实)6、独立结构。
如:To tell you the truth, I don’t agree with you.To make matters worse, it began to 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 to see 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 given you so much trouble.He seems to have caught a 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 t o have been working on the problem for 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 to enter the hall.三、省to 的动词不定式1、情态动词(除ought 外,ought to)2、Would rather, 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 saw him dance. He was seen to dance. The boss made them work the wholenight.They were made to work the whole night.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:He wants to move toFrance and marry the girl.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 do nothing but go out.He wants to believe anything but to 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。
