动词不定式用法大全

动词不定式用法大全英语动词的非谓语形式为三种:动词不定式、动名词和分词。
非谓语动词没有人称和数的变化。
动词不定式是一种非谓语动词形式,其结构为“to+动词原形”,其中to 不是介词,而是动词不定式的符号,称为小品词,动词不定式没有人称和数的变化。
动词不定式和其后面的名词等构成不定式短语,在句子中可以用作主语、表语、宾语、补足语、定语、状语等。
一. 作主语例如:To be a doctor is hard. 做医生很难。
To learn English well is not easy. 学好英语不容易。
To say is to believe.眼见为实。
动词不定式(短语)作主语时,为了避免句子的头重脚轻,可以用“it”作形式主语,而把真正的主语--动词不定式(短语)放在句子的后部。
例如上面的句子可以表示为:It is hard to be a doctor。
It is not easy to learn English well. 再如:It's important to plant trees in spring.如果动词不定式的动作是谁做的,可以在动词不定式前面加一个由介词for引导的短语,称为不定式的复合结构。
例:It’s good for us to read English aloud in the morning.对我们来说每天早晨大声读英语是很有益的.It is important for students to use English every day.对学生来说每天使用英语是很重要的.二。
作表语:(在形式上,位于系动词后的就是表语。
从含义上讲,表语是回答主语“是什么"或“怎么样"的语法成分。
)动词不定式(短语)作表语常用于系词be的后面。
例:His work is to drive a car. 他的工作是开车.My job is to feed animals. 我的工作是饲养动物。
动词不定式

动词不定式特征:动词不定式没有人称和数的变化,在句中不能独立作谓语。
结构:动词不定式的肯定形式是to+do;否定形式是not to+do。
1.作主语可以直接作主语。
如:To see is to believe.眼见为实。
但在英语中,常用it作形式主语,真正的主语即动词不定式放在后面。
如:It's wrong to play tricks on other people.规律:动词不定式在句中作主语时,常放在It is +adj.(形容词)+to do sth.句型中,it仅作形式主语。
真正的主语为动词不定式。
2.作宾语1)want,decide ,agree,would like等动词后面跟并且只能跟不定式。
如:We agreed/wanted/decided/would like to start early2)love,like ,begin,start,hate ,prefer等词后可加to do 或者doing。
提示板:like doing指经常性动作,而like to do指一次性的动作。
如:I like swimming,but I don't like to swim now.我喜游泳,但现在不想游。
3)stop,forget,remember,go on ,try等词或短语后面可以接不定式或者ING。
但是意思区别很大。
如:stop to do sth.:停止一件事,去做另一件事。
stop doing sth.:停止正在做的事。
Forget/remember to do sth: 忘记/记得去做某事Forget /remember doing sth:忘记、记得做过某事。
go on to do sth: 接着做另外一件事Go on doing sth: 接着做同一件事情Try to do sth:努力去做某事Try doing sth:尝试做某事3.作宾语补足语1)tell,ask,want,order,teach,invite,warn,wish,help,get,wish,help 等词后面常接不定式作宾补。

动词不定式的结构及用法

动词不定式的结构及用法 源自动词不定式:(to)+do,具有名词、形容词、副词的特征. 否定式:not + (to) do (1)一般式:不定式的一般式所表示的动作与谓语动词动作同时发生或发生在谓语动词动作之后. 例如: I'm glad to meet you. He seems to know a lot. We plan to pay a visit. He wants to be an artist. The patient asked to be operated on at once. The teacher ordered the work to be done. (2)进行式:不定式的进行式所表示的动作与谓语动词动作同时发生,例如: The boy pretended to be working hard. He seems to be reading in his room. (3)完成式:不定式的完成式表示的动作发生在谓语动词动作之前,例如: I regretted to have told a lie. I happened to have seen the film. He is pleased to have met his friend. 2.不定式的句法功能: (1)作主语: To finish the work in ten minutes is very hard. To lose your heart means failure. 动词不定式短语作主语时,常用it作形式主语,真正的主语不定式置于句后,例如上面两句可用如下形式: It is very hard to finish the work in ten minutes. It means failure to lose your heart. 常用句式有:1、It+be+名词+to do。2、It takes sb.+some time+to do。3、It+be+形容词+of sb +to do。4、It+be+形容词+for sb.+to do。常用careless,,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise,等表示赞扬或批评的形容词,不定式前的sb.可作其逻辑主语。 (2)作表语: Her job is to clean the hall. He appears to have caught a cold. (3)作宾语: 常与不定式做宾语连用的动词有:want, hope, wish, offer, fail, plan, learn, pretend, refuse, manage, help, agree, promise, prefer, 如果不定式(宾语)后面有宾语补足语,则用it作形式宾语,真正的宾语(不定式)后置,放在宾语补足语后面,例如: Marx found it important to study the situation in Russia. 动词不定式也可充当介词宾语,如: I have no choice but to stay here. He did nothing last Sunday but repair his bike. 动词不定式前有时可与疑问词连用,如: He gave us some advice on how to learn English. (4)作宾语补足语: 在复合宾语中,动词不定式可充当宾语补足语,如下动词常跟这种复合宾语:want, wish, ask, tell, order, beg, permit, help, advise, persuade, allow, prepare, cause, force, call on, wait for, invite. 此外,介词有时也与这种复合宾语连用,如: With a lot of work to do, he didn't go to the cinema. 有些动词如make, let, see, watch, hear, feel, have等与不带有to的不定式连用,但改为被动语态时,不定式要加to, 如: I saw him cross the road. He was seen to cross the road. (5)作定语: 动词不定式作定语,放在所修饰的名词或代词后。与所修饰名词有如下关系: ①动宾关系: I have a meeting to attend. 注意:不定式为不及物动词时,所修饰的名词如果是地点、工具等,应有必要的介词,如: He found a good house to live in. The child has nothing to worry about. What did you open it with? 如果不定式修饰time, place, way,可以省略介词: He has no place to live. This is the best way to work out this problem. 如果不定式所修饰名词是不定式动作承受者,不定式可用主动式也可用被动式: Have you got anything to send? Have you got anything to be sent? ②说明所修饰名词的内容: We have made a plan to finish the work. ③被修饰名词是不定式逻辑主语: He is the first to get here. (6)作状语: ①表目的: He worked day and night to get the money. She sold her hair to buy the watch chain. 注意不定式放句首时,逻辑主语与句子主语要一致: wrong:To save money, every means has been tried. right:To save money, he has tried every means. wrong:To learn English well, a dictionary is needed. right:To learn English well, he needs a dictionary. ②表结果(往往是与预期愿望相反的结果): He arrived late only to find the train had gone. I visited him only to find him out. ③表原因: They were very sad to hear the news. ④表程度: It's too dark for us to see anything. The question is simple for him to answer. (7)作独立成分: To tell you the truth, I don't like the way he talked. (8)不定式的省略:保留to省略do动词。 If you don't want to do it, you don't need to. (9)不定式的并列:第二个不定式可省略to。 He wished to study medicine and become a doctor.
动词的不定式

动词不定式动词不定式在中学英语中应用非常广泛,一方面在句中可以起名词,形容词,或副词的作用,同时也可在句中做主语,宾语,表语等。
动词不定式的形式一般是“to+动词原形”,但是to 有时候可以省去。
(一)不定式做主语动词不定式做主语时,句子中谓语动词常用单数,其位置有以下两种。
1.把动词不定式置于句首。
To see is to believe .百闻不如一见2.用it 做形式主语,把真正的主语不定式放在后面,常有以下句型(1).It+be +名词+to do sth.It’s our duty to take good care of the old. 好好照顾老人是我们的责任。
(2)It takes sb +some time +to do sthHow long did it take you to finish the work? 完成这项工作你花了多少时间(3)It +be+形容词+for sb+to do sth.It’s necessary for you to lock the car.锁车是很有必要的。
(4)It +be +形容词+ of sb+to do sth.It was silly of us to believe him.我们真愚蠢,竟然相信了他的话。
(5)It seems\appears +形容词+to do sth.It seemed impossible to save money.省钱看起来是不可能的(二)动词不定式做宾语能以不定式做宾语的动词很多,常见的有:want,like,wish,hate,prefer,hope,continue,manage,try,ask,offer,start,forge t,promise,mean,pretend,intend,begin,attempt,decide,learn,desire,agree, care,choose,determine,undertake,expect等。
动词不定式

C-不定式的概念、作用语法梳理不定式一、概念:在语法中,动词不定式是指动词的一种不带词形变化从而不指示人称、数量、时态的形式。
形式为:to+动词原形+其他。
之所以被叫做不定式,是因为动词不被限定,或者说不被词形变化所局限。
不定式属于非谓语动词。
不定式的时态有:一般式、进行式、完成式和完成进行式。
二、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(取消,否定)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 managed to escape from the fire.I find it hard to get along with him.(it 作形式宾语)(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。
动词不定式

• 二、功能如同名形副 不定式在句子中相当于名词、形容词、副词。 1、不定式可以作主语、宾语和表语,相当于一个名 词,如: To see is to believe. 眼见为实。 注意:在系表结构中,当主语是表示目的的名词(如 purpose、aim、objective、goal、intention等)时,表语要 用不定式,如: Our goal is to satisfy customers' needs. 我们的目标 是满足顾客的需要。 2、不定式可以作定语和补语,相当于一个形容词, 如: John is the first disabled person to sail around the world. 约翰是第一个环球航行的残疾人。 3、不定式可以作状语,相当于一个副词。不定式常 作目的状语,此时它也常用于一些固定搭配(如in order to、 so as to等),如: Many people open blogs so as to exchange their own views and thoughts with others. 许多人创建博客, 以便和他人交流自己的观点和看法。
• 动词不定式 • 动词不定式在中学英语中应用非常广泛,一方 面在句中可起名词、形容词或副词的作用,同 时也可在句中作主语、宾语、定语、状语和宾 语补足语。动词不定式的形式一般是to +动词 原形,但to有时要省去。而动词不定式在具体 运用时用不用to,取决于谓语动词的用法。现 就以下几方面介绍如下。
•
地点状语从句 (adverbial clause of place) 地点状语 从句一般由连接副词where, wherever等引导,已经形成 了固定的句型.
• Where+地点从句,( +地点从句,(there)+主句。 )+主句 【注意】此 ,( )+主句。 句型通常译成“哪里……哪里就……”;主句在从句后面 时,there可用可不用;如果主句在从句的前面时,一般 都不用there。例如: Where there is no rain, farming is difficult or impossible.在没有雨水的地方,耕作 是困难的,或根本不可能的。 They were good persons. Where they went, there they were warmly welcomed. 他们都是好人。因此他们走到哪里都受到热烈 欢迎。 You should have put the book where you found it. 你本来应该把书放回原来的地方。 Where the Communist Party of China goes, there the people are liberated.哪里有了中国共产党,哪里人民得解放。
