非谓语动词——不定式非谓语动词包括不定式(to do)、动名词(-ing)、现在分词(-ing)与过去分词(-ed)。
它们不受主语人称和数的限制,在句子中不能充当谓语,但可以充当句子的其他成分,并且有时态和语态的变化。
注:现在分词、不定式、过去分词都可以作独立成分。
II.基本知识一、不定式的构成动词不定式的基本形式是“to+动词原形”,这里的to是不定式标志,没有词义。
有时可以不带to。
动词不定式在句子中不能作谓语,但可以担任除谓语外的任何成分——主语、表语、宾语、定语、状语和宾语补足语。
不定式具有名词、形容词或副词的某些语法功能,又有动词的时态和语态的特点及作用,可以有自己的宾语和状语。
动词不定式没有人称和数的变化,但是有时态和语态的变化。
常见的形式如表所示(以及物动词do为例),不及物动词没有被动语态。
1. 不定式的一般式:一般式表示的动作或状态发生在谓语动词表示的动作或状态的同时或之后。
当不定式的逻辑主语是这个不定式所表示的动作的承受者时,不定式一般要用被动式(to be done).eg: He seemed to be tired.The building to be finished next month is for our teachers.2. 不定式的进行式:进行式表示动作正在进行,与谓语的动作同时发生。
e.g. When I went to his home, he happened to be traveling around the world.3. 不定式的完成式:如果不定式所表示的动作或状态发生在谓语动词所表示动作或状态之前,就用完成式;若是在此基础上的被动含义,就用完成被动式( to have been done).e.g. He is said to have written a novel about the Long March.He is said to have been taught French when he was a child.4. 不定式的完成进行式:如果不定式的动作是在谓语所表示的时间之前一直在进行或有可能继续进行的动作,就要用完成进行式.eg. We’re happy to have been working with the experts all the month.二、不定式的用法:1. 动词不定式做主语:不定式做主语一般表示具体的某次动作。
非谓语动词中的动词不定式非谓语动词中的动词不定式非谓语动词也是动词的一种,他们有着动词的特点,还可以充当主语、宾语、状语等。
以下是我细心整理的非谓语动词中的动词不定式,欢送大家共享。
动词不定式的形式为(to)+do/be done,其中to有时要省略。
通常所说的“动词原形”其实质就是不带to的不定式形式。
不定式具知名词、形容词和副词的性质。
它的否认形式为not+(to)do/be done。
一、不定式的时态性不定式从时态角度讲,具体形式分为一般式、进展式和完成式,是以不定式动作与谓语动词发生的时间的比较确定的。
具体状况如下:1、一般式不定式的一般式所表示的不定式动词与谓语动词同时发生或发生在谓语动词动作之后。
【例句】Tom plans to take part in the postgraduate entrance exams.汤姆打算要考研。
2、进展式不定式的进展式表示与谓语动词动作同时发生。
【例句】Tom pretended to be fully sleeping.汤姆装作睡得很沉。
3、完成式不定式的完成式表示发生于谓语动词动作之前。
【例句】Tom is pleased to have met his friend who has not kept intouch for many years.汤姆很兴奋能遇上他多年未联系的伴侣。
二、不定式的句子成分属性不定式如其他非谓语动词一样可以充当多种句子成分,包括主语、表语、宾语、宾语补足语、定语以及状语。
1、作主语【例句】To accomplish the budget in a month is impossible.在一个月内完成预算是不行能的。
2、作表语【例句】My wife’s task is to take charge of loveliness.我老婆的'任务是负责”得意”。
3、作宾语1〕假设谓语动词为find,want,hope,wish,offer,fail,plan,learn,pretend,refuse,manage,help,agr ee,promise,prefer时,不定式〔宾语〕后面存在宾语补足语成分,要用it作形式宾语,真正的宾语〔不定式〕后置于句尾,放在宾语补足语后面。
非谓语动词之动词不定式一、动词不定式表目的,如:I went to the post office to mail a letter.注意:强调动词不定式表示目的时,动词不定式可用in order to或so as to + 动词原形。
so as to不用于句首。
1:(2011四川,11)Simon made a big bamboo box the little sick bird till it could fly. (keep)Simon做了一个大竹箱为了养这只生病的小鸟直到它会飞为止。
2:(2011重庆,29)More TV programs, according to government officials, will be produced food safety. (raise)在政府官员看来,我们应该制作更多的电视节目来引起人们对食品安全的关注。

非谓语动词之动词不定式(to do)的用法非谓语动词是指在句子中不是谓语的动词,主要形式有:不定式、动名词和分词(现在分词和过去分词)。
1.“to do”动词不定式的变形2.动词不定式的用法(1)充当主语(一般会用it 当形式主语)To swim here is dangerous. =It is dangerous to swim here.To pass this English exam is unlikely. =(2)充当表语(多数情况下,可以转换成动词不定式做主语)My job is to help with your English learning.To help with your English learning is my job.(3)充当宾语(只能做某些动词的宾语,一般不做介词的宾语;有时用“it”做形式宾语)I decided to attend this meeting last night.I find it necessary to learn a foreign language.注意:当以下动词欲接动词作宾语时,只能跟不定式作宾语。

英语非谓语动词:不定式,动名词和分词非谓语动词分为三种形式:不定式、动名词和分词(包括现在分词和过去分词)(一)动词不定式动词不定式可以作主语、宾语、宾语补足语、定语、状语、表语。
动词不定式由“to+动词原形”构成,否定形式“not to +动词原形”。
1.用法(1)作主语。
往往用it作为形式主语。
如:It is time to get up.(2)作宾语。
如果带有宾语补足语,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 interesting to study English.有些动词只能用动词不定式作宾语。
如:decide,plan,desire,hope,wish,promise,ask,agree, manage等。
(3)作宾语补足语A:带to的动词不定式有:ask,tell,want,teach,advise,allow,beg,invite等。
如:He asked me to do the work.B :接不带to的动词不定式有:see,watch,hear,make ,let等。
如:I often see him play football.使役动词不带to,动词有:一感二听三让四观看。
一感:feel 二听:hear, listen to 三让:let,have,make 四观看:observe,see,watch,look at注意:feel, hear,notice, see,watch,have,make等词后的补足语中,不定式不带to,但变成被动结构时,要带to.如:I often hear him cry. He is often heard to cry.注意:带but介词的不定式。
如果介词之前有行为动词do的各种形式,那么but后的不定式不带to,否则要带to。
另外,在can’t choose but...和can’t help but...等后面的不定式也省略to。
在英语中,不做句子谓语,而具有谓语外其他语法功能的动词中,叫“非谓语动词”非谓语动词包括:动词不定式(the Infinitive)动名词(the Gerund)现在分词(the Present Participle)过去分词(the Past Participle)Ⅰ。
动词不定式:动词不定式有两种,带“to”和不带“to(动词原型)”,有人称之为“光秃不定式”,在大多数情况下不定式都带to,动词不定式由“to+动词原型”,这里的to是不定式标志,没有词义,不定式具有名词,形容词,或副词的某些语法功能,又有动词的时态和语态。
一:1。
不定式做主语:eg : To over come the problem is very difficult不定式做主语,往往用it做形式主语,真正的主语不定式放置句子后面:eg : It‟s so nice to hear your voice.但是,用不定式做主语的句子中还有一个不定式做表语时,不能用it‟s…to…的句型eg : To teach is to learn.比较“it‟s for sb和it‟s of sb1)for sb句型中的形容词一般为表示事物的特征特点,表示客观形式的形容词,如”easy, hard, difficult, impossible”等2)of sb句型中的形容词一般为表示性格,品德,心智能力,表示主观感情或态度的形容词,如”good, kind, nice, clever, foolish”等3)用介词for或者of后面的逻辑主语做句子的主格,用介词前边的形容词做表语,造这个句子,如果通顺用of,不通则用for2.不定式做表语:不定式可放在be动词后面,形成表语eg : My dream is to be a teacher.3.不定式做宾语1)有些及物动词用不定式做宾语,结构为“动词+不定式”P2892)有些动词除了可以用不定式做宾语,还用些不定式做补语,即“动词+宾语+不定式”结构eg : I like to keep everything tidy.I like you to keep everything tidy.3)有些动词或动词词组可以用“动词+疑问词+不定式”的结构:eg : I want to know how to solve the problem.4)如果不定式(宾语)后面有宾语补足语,则用“ it ”做形式宾语,真正的宾语(不定式)后置,放在宾语补足语4.不定式做补语1)有些动词+宾语+不定式P291eg : Father will not allow us to play on the street.2)有些动词+宾语+不定式的结构,不定式的动词往往是be,不定式一般可以省去eg : We believe him (to be) quilty (adj.)我们相信他是有罪的We know him to be fool. (n.) (to be不能省)3)有些动词可以跟”there + to be的结构eg : We didn‟t expect there to be so many people.You wouldn‟t want there to be another war. 你不至于想让另外一场战争发生吧?5.不定式做定语不定式做宾语,通常要放在被修饰的词后,往往表示未发生的动作。
非谓语动词共分为三种,构成形式如下:1.动词不定式(Infinitives):2.现在分词和过去分词(present participles & past participles):3. 动名词(gerunds)下面我们依据句子的成分,来具体分析非谓语动词的不同用法。
1.非谓语动词做主语和表语主语、表语和同位语在句子中用名词来担当,非谓语动词中动词不定式和动名词均可以用作名词,因此,动词不定式和动名词可以用来担当这三种成分。
1)非谓语动词做主语一般情况下,用动名词来做主语的情况比拟多,动词不定式用作主语的情况比拟少。
通常来说,在表达将来的要发生的事情时用不定式来作主语,而表达一般情况习惯性的动作时用动名词来作主语。
例如:Teaching is a tiring but satisfying job.Swimming is a good kind of e*ercise.To be an astronaut is Johnson’s desire.在用it做形式主语的句子中通常用动词不定式来做真正的主语。
例如:It is necessary (for you) to give up smoking.It is everyone’s duty to protect the environment.但是值得注意的是在各别情况下,即使是It做形式主语,真正的主语也必须用动名词,这些情况很少,所以希望同学们能单独记忆下来,以下是此类情况的一个总结。
It is/was no use/good doing sth.It is/was not any use/good doing sth.It is/was of little use/good doing sth.2)非谓语动词做表语非谓语动词作此成分的时候跟作主语时的规则根本一致。
在表示"目的,愿望,梦想,需求〞等名词做主语时其表语应该用不定式.例如:Her wish was to bee an artist.她的愿望是成为一位艺术家Our aim is to help them,not to teach them a lesson.我们的目的是帮助他们,而不是教训他们。
非谓语动词顾名思义,非谓语动词就是不能作谓语的动词。
包括:不定式、现在分词、过去分词和动名词。
不定式1.不定式的构成不定式是由不定式符号to+动词原形构成,在某些情况下to也可省略。
不定式一般有时态和语态的变化,通常有下表中的几种形式(以do为例):主动式被动式一般式to do to be done完成式to have done to have been done进行式to be doing /完成进行式to have been doing /1). 不定式的一般式不定式的一般式所表示的动作通常与主要谓语的动作同时或几乎同时发生,或是在它之后发生。
如:They invited us to go there this summer. 他们邀请我们今年夏天去那儿。
He stood aside for me to pass. 他站到一边让我通过。
2). 不定式的完成式不定式的完成式所表示的动作在谓语所表示的动作之前发生,它在句中可作表语、状语、宾语,有时也可作主语、定语等。
如:She seemed to have heard about this matter. 她似乎已听说过这件事。
I am sorry to have kept you waiting so long. 我很抱歉让你等了这么久。
I meant to have told you about it, but I happened to have an important thing to do.我本来想告诉你这件事的,但我碰巧有一件重要的事要做。
It has been an honor for me to have traveled so much in your country.对我来说,在你们国家旅行这么多地方是一件很荣幸的事情。
3). 不定式的进行式不定式的进行式表示正在进行的与谓语动词同时发生的动作。
它在句中可以用作除谓语以外的所有成分。
如:It’s nice of you to be helping us these days.你真好,这些天一直帮我们。
He pretended to be listening to the teacher carefully. 他假装在认真地听老师讲课。
We didn’t expect you to be waiting for us here. 我们没料到你一直在这儿等我4). 不定式的完成进行式如果不定式表示的动作是谓语所表示时间之前一直进行的动作,就需要用完成进行式。
如:They are said to have been working in Tibet for 20 years. 据说他们已经在西藏工作20年了。
We are happy to have been helping each other these days. 我们很高兴这些天能互相帮助。
5). 动词不定式的否定形式是由not或never加不定式构成。
如:Try not to be late again next time. 尽量下次不要再迟到。
He wished us never to meet her again. 他希望我们永远不要再见到她。
6). 疑问词+动词不定式:不定式和疑问词whether, what, which, whom, where, when, how, why等连用可以在句中起名词的作用,通常跟在tell, know, show, decide, learn, wonder, explain, advise, teach, discuss, find out等动词后面作宾语,有时也可以充当主语、表语等。
如:On hearing the news, he didn’t know whether to laugh or to cry.听到这个消息,他不知道该哭还是该笑。
When to hold the meeting has not decided. 什么时候开会还没有决定。
The most important problem is how to get so much money. 最重要的事情是如何搞到这么多钱。
介词后一般不直接接不定式,但可以接疑问词+不定式短语作宾语。
如:Mary gave some advice on how to learn English. 玛丽提了一些如何学习英语的建议。
I have no idea of how to do it. 我不知道该怎么做。
但是but和except后面可以跟不定式。
如:He did nothing but wander on the street. 他除了在街上闲逛外,没有做什么。
I have no choice but to wait. 我除了等待以外别无其他选择。
7). 不定式的被动式:当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时,不定式一般要用被动形式,to be +过去分词和to have been +过去分词。
这些形式可以用来作主语、表语、宾语、定语、状语、补语。
如:It’s a good thing for him to have been scolded by the te acher.对他来说,被老师责备是一件好事。
They seemed to be satisfied with the result. 他们似乎对结果很满意。
He asked to be sent to work in the countryside. 他要求被派往农村工作。
She was the last person to have been mentioned at the meeting. 她是会上最后一个被提到的人。
I had to shout to be heard. 我不得不大喊才能被听到。
We don’t like our friends to be laughed at from time to time.我们不喜欢我们的朋友不时地被嘲笑。
2. 不定式的语法作用1) 不定式作主语:To see once is better than to hear a hundred times. 百闻不如一见。
To master a foreign language is not an easy thing. 掌握一门外语不是一件容易的事。
在很多情况下,人们通常用it作为形式上的主语,而把不定式短语移到谓语之后,使句子显得平稳一些。
如:It’s good manners to wait in line.排队等候是很有礼貌的。
It made us very angry to hear him speak to his mother like that.听到他那样跟他妈妈说话我们很生气。
2) 不定式作表语:The most important thing is to put theory into practice. 最重要的事情是把理论付诸实践。

I prefer to be starved to death rather than beg. 我宁愿被饿死也不愿乞讨。
He pretended to have read the book when I asked him about it.我问到他的时候,他假装读过这本书。
另外,不定式在某些复合宾语中作宾语时,人们常常用it代表不定式,而将真实宾语放在补足语之后。
如:Do you think it better to translate it in this way? 你认为这样翻译是不是更好?I feel it a great honor to be invited to speak at the meeting before so many students.我觉得被邀请在会上面对这么多学生发言是一件很光荣的事情。
4) 不定式作补语:①不定式可以和名词或代词一起构成复合结构作动词的宾语,这时不定式被称为宾语补足语。
如:I would like you to help me with my English exercises. 我想请你帮我做英语练习。
I never expected the shoes to be worn out so soon. 我从来没想到鞋子这么快就穿破了。
注意:动词help后面接不定式作宾语或宾语补足语可以带to也可以不带to。
如:Who can help me (to) carry this heavy box? 谁能帮我拎这个重箱子?②在make, let, have等使役动词和hear, see, watch, notice, feel,observe等感官动词后的复合宾语中,动词不定式不带to。
I often hear her sing in the next room. 我经常听到她在隔壁唱歌。
They make the baby go to bed at 7:00 p.m. every day. 他们每天让孩子晚上7:00上床睡觉。
注意:get, leave等词也有“让”“叫”的意思,和使役动词意思相近,但它们后面的不定式作宾语补足语必须要有to。
如:I’ll get him to try it again.我将让他再试一次。
How could you leave him to have supper with a stranger? 你怎么让他跟一个陌生人一起吃晚饭?注意:当使役动词和感官动词变为被动语态时,不定式就成了主语补语,作主语补语的不定式必须加to。
如:Though he had often made his little sister cry, today he was made to cry by his little sister.尽管他经常弄哭他的小妹妹,但今天他却被他的小妹妹弄哭了。
He is often heard to sing the song. 经常有人听到他唱这首歌。
③think, consider, believe, declare, suppose, find, imagine, know, understand, take, prove, feel等动词后面接的不定式短语作补语多由to be+形容词或名词构成,think, consider, find后的to be常可省略。
