动词(非谓语动词3
动词的非谓语形式有三种

动词的非谓语形式有三种:不定式、动名词和分词。
一、不定式由“to+动词原形”构成,其否定形式是“not to do”。
不定式可以带宾语或状语构成不定式短语。
不定式没有人称和数的变化,有时态和语态的变化。
不定式可以作主语、宾语、状语、表语和定语。
不定式复合结构为“介词+sb.(sth.)+to do”,其中“介词+sb.(sth.)”表明不定式动作的发出者,为逻辑主语。
1. 不定式的用法:(1)作主语。
不定式短语作主语时,为了使句子结构平衡,常将不定式短语放在谓语之后,而用it作形式主语。
It is our duty to give as much help as possible. 提供尽可能多的帮助是我们的职责。
但不定式作表语时,前面有不定式作主语,不定式不可位于句末。
如:To see is to believe. 眼见为实。
(2)作宾语。
常见的只跟不定式作宾语的动词(组)有want, wish, hope, expect, would like (love),care, choose, learn, plan, prepare, mean, agree, promise, offer, refuse, ask, beg, decide, make up one’s mind, be determined, manage, try, can’t afford, fail, pretend等。
He promised to come today, but he hasn’t turned up yet .No one likes to be laughed at. 没人喜欢被嘲笑。
有形容词、分词、名词作宾补,不定式作宾语时要将不定式放于句末,用it 来作形式宾语。
如:You may find it necessary to finish the work ahead of time. 你会发现有必要提前完成工作。

动词的非谓语形式

动词的非谓语形式:动词不做谓语时的固定形式。
(1) 动词的非谓语形式包括动词不定式、动名词和分词三种形式;其中分词又包含现在分词和过去分词两种形式。
它们在句子中不能单独作谓语。
(2) 动词不定式:①形式:动词不定式基本形式由“不定式记号to+动词原形”构成。
它的否认形式只要在“to” 前面加上“not”。
它的疑问形式是:“wh-疑问词+to+动词原形”。
*它的被动形式:“to be +过去分词”。
*它的完成形式:“to have +过去分词”。
②动词不定式具有名词、形容词和副词的特征,即可以在句子中作主语、宾语、定语、状语、表语和宾语补足语。
但不定式也保留动词的某些特征,即不定式后面可以跟宾语、表语和状语。
动词不定式加上相关成分就构成不定式短语。
③动词不定式可以放在谓语前句子作主语。
但是通常将作主语的动词不定式或不定式短语放在谓语后面,而在主语位置用“it”作形式主语(有时在不定式的前面还会用for sb.表示不定式的逻辑主语)。
如:To help animals is helping people.(帮助动物就是帮助人)/ It is very difficult (for us) to learn Chinese well.((对于我们而言)学好汉语是非常的困难)/ It took me half an hour to work out this problem.(解出这道题花了我一个小时的时间)④动词不定式可以作谓语动词(及物动词)的宾语。
[A] 及物动词+不定式一般形式:如:I would like to have a rest at the moment.(我现在想休息一下)/ They began to search the room for the thief.(他们开始在屋子里搜寻小偷)/ He liked to have aswim in the pool near his house.(他喜爱在靠家的水塘里面游泳)/ When did you learn to speak English?(你什么时候开始学英语的?)/ Don’t forget to close the door when you leave.(你离开时别忘了关门)[比较] He forgot to turn off the light.(他忘了关灯.) (没关)/ He forgot turning off the light.(他忘记关过灯.)(关了) / Please remember to ring me up.(记得给我打.)(还没打) / I remember calling you yesterday but you forgot.(我记得昨天给你打了,但是你忘记了.)(打过)[B] 及物动词+疑问词+不定式:如:He does not know which one to take.(他不知道该选哪个)/ Tell me how to get to the station.(告诉我怎么样去火车站)/ She asked me what to do for today’s homework.(她问我今天家庭作业做什么)/ Can you teach me how to search the internet?(你能教我怎样上网吗?)[C] 不定式作宾语而后面又有宾语补足语时,通常用it代替作形式宾语,而不定式则后置。

往往把不定式宾语放在宾语补足语之后,而用it作形式宾语.例如:He wanted to go.Ifind it interestingto study work with him.3)作宾语补足语.例如:Heasked me to do the workwith him.注意:在feel,hear,listento,lookat,notice, observe,see,watch,have,let,make等词后的补足语中,不定式不带to.但是这些句子如果变成被动结构时,就必须带to.例如I oftenhear himsingthe song.He is often heard to singthesong.注意:不定式动词在介词but,except,besides后面时,如果这些介词之前有行为动词do的各种形式,那么,这些介词后的不定式不带to,否则要带to.如:She could do nothing but cry.What doyou liketodo besidesswim?I havenochoicebutto go.4)作定语.例如:Ihave some booksfor you to read.注①作定语的不定式如果是不及物动词,或者不定式所修饰的名词或代词是不定式动作的地点、工具等,不定式后面须有相应的介词.例如:He is looking for a room to livein.There is nothing toworry about.Please giveme aknifeto cutwith.但是,不定式所修饰的名词如果是time,place或way,不定式后面的介词习惯上要省去.例如:He hadno moneyandno placeto live.注②当作定语的不定式所修饰的名词或代词是不定式动作的承受者时,不定式既可以用主动语态,也可用被动语态,但其含义有所不同.试比较:A) Have you anything tosend? 你有什么东西要寄吗?(不定式tosend的动作执行者是you)B)Have you anything to be sent?你有什么要(我或别人)寄的东西吗?(不定式tobesent的动作执行者是已被省略的me或someoneelse)5)作状语,表示目的、原因、结果或条件.例如:I came here to see you.(目的)We were very excitedtohearthe news.(原因)He hurriedto the schooltofind nobody there.(结果)Tolook at him, you would like him.(条件)目的状语还可以用inorder to或so as to来表示.如:In order topass the exam, he worked very hard.We ranall theway so as not to be late.不定式也可在作表语用的形容词后面作状语.例如:Iamvery glad tohearit.The question is difficult toanswer.“too十形容词或副词十不定式”作状语.例如:He istoo old todo that.另外句子中有enough这个词时,常用不定式作状语.例如:The room is big enoughtohold us.6)作表语.例如:My job is to help the patient.7)作独立成分.例如:To tell thetruth,I don’t agree with you.8)不定式与疑问词who,which,when,where,how,what等连用,在句中起名词作用,可充当主语、表语、宾语等.例如:He didn’t know what tosay.(宾语)How to solve the problem is veryimportant.(主语)My question is when to start. (表语)注意:在与why连用时,只用于why或why not开头的简短疑问句中,后面紧跟的动词不定式不带to.例如:Why not have a rest?9)不定式在句中用主动式还是被动式。

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。

非谓语动词的三种形式

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。
