动词不定式归纳定义:不定式的to和介词to需要被区分开,不定式的to后接动词原形,介词to后接名词、代词或动名词。
不定式作动词宾语He decided to invite all of his classmates to attend the holiday at the beach. 不定式作宾语He promised not to tell anyone about it.如果宾语有自己的补语,则常用it作形式宾语,而把真正作宾语的不定式放在后面放在后面,常带有形式宾语的动词有:believe. Consider. Feel. Find. Know. Make . regard例:we think it important to obey the laws. √we think to obey the laws is important. ×I know it impossible to finish so much homework in a day.不定式作介词宾语当介词but、except、besides前面有行为动词do及其各种形式时,介词后面的不定式可以省略to,否则不省略。
What do you like to do besides play football?We have no choice but to wait.个别介词可以用“疑问词+不定式”作宾语The boy has him own idea of how to finish it.不定式起形容词作用作定语不定式作定语用来修饰名词或代词,置于它所修饰的词后,而且放在其他后置定语的后面。
同时与它所修饰的名词或代词形成逻辑上的动宾关系或主谓关系。
He always has a lot of meetings to attend. 不定式to attend 和名词meetings 形成动宾关系The next train to arrive was from Seattle. To arrive 和train形成主谓关系Do you have anything interesting to read?如果作定语用的不定式是不及物动词,就要加上介词,使被修饰的这个词成为这个介词的逻辑宾语。

练习一:选择正确的动词不定式形式。
1. She asked me _________ her the book.a) to give b) give c) giving d) gave2. I hope _________ to the party tonight.a) to go b) go c) going d) went3.

人教版高二英语动词不定式和动名词用法区别练习题20题【含答案解析】1. ______ early in the morning is good for your health.A. Get upB. Getting upC. To getting upD. Got up答案解析:B。
在这个句子中,需要一个词作主语,表示“早起”这个行为。
动词不定式和动名词都可以作主语,但动词原形不能作主语,所以A选项错误。
C选项“to getting up”形式错误,不定式是“to+动词原形”。
动名词作主语表示抽象的、一般性的行为,而动词不定式作主语往往表示具体的某次行为或者目的。
这里说的是一般性的“早起对健康有益”,所以用动名词Getting up。
2. She likes ______ books in the library.A. to readB. readingC. readD. being read答案解析:B。
“like”这个动词后面既可以接动名词也可以接动词不定式作宾语,但表达的含义略有不同。
动名词表示一种习惯性的、一般性的喜好,动词不定式表示具体某一次的喜好。
这里说“她喜欢在图书馆看书”,是一种习惯性的行为,所以用动名词reading。
C选项read是动词原形,不能直接跟在likes后面;D选项being read是被动形式,不符合题意。
3. His dream is ______ a famous singer.A. becomeB. to becomeC. becomingD. became答案解析:B。
在这个句子中,“is”后面需要一个词作表语,表示将来的动作或者目的时,常用动词不定式作表语。
动名词作表语表示抽象的、一般性的概念,这里说“他的梦想是成为一名著名歌手”,是一个将来的目标,所以用动词不定式to become。
A选项become是动词原形,不能直接作表语;D选项became是过去式,也不符合要求。
八年级英语动词不定式练习题20题答案解析版1. My mother wants me ____ the dishes after dinner.A. washB. to washC. washingD. washed答案:B。
解析:want sb. to do sth.是固定用法,表示想要某人做某事。
A选项wash是动词原形,不能直接用在want sb.后面;C选项washing是现在分词形式,不符合want的用法;D选项washed是过去式和过去分词形式,也不符合want的用法。
2. It's important ____ us to learn English well.A. forB. ofC. toD. with答案:A。
解析:It's + adj. + for sb. to do sth.是常用结构,表示对某人来说做某事是怎么样的。
这里的important是形容做某事(to learn English well),而不是形容人 us),如果是形容人的品质特征用of,这里不符合,C选项to和D选项with不符合这个结构。
3. Her dream is ____ a famous singer.A. becomeB. to becomeC. becomingD. became答案:B。
解析:动词不定式to become在句中作表语,表示具体的将来的动作或目的。
A选项become是动词原形,不能直接作表语;C选项becoming是现在分词形式,不能作表语表示这种含义;D选项became是过去式,也不符合表语的用法。
4. We decided ____ to the park this Sunday.A. goB. to goC. goingD. gone答案:B。
解析:decide to do sth.是固定搭配,表示决定做某事。
A选项go是动词原形,不能用在decide后面;C选项going是现在分词形式,不符合decide的用法;D选项gone是过去分词形式,也不符合。
八年级英语动词不定式练习题40题(带答案)1. My mother wants me ______ the dishes after dinner.A. washB. to washC. washingD. washed答案解析:B。
在这个句子中,“want sb. to do sth.”是一个固定结构,表示“想要某人做某事”,这里的动词不定式“to wash”作宾语补足语,补充说明“me”要做的事情。
选项A“wash”是动词原形,不能直接用在“want sb.”后面;选项C“washing”是现在分词形式,不符合这个结构的用法;选项D“washed”是过去式和过去分词形式,也不适合这里的结构。
2. It's important ______ us to learn English well.A. forB. ofC. withD. to答案解析:A。
“It is + 形容词+ for sb. to do sth.”是一个常用结构,表示“对某人来说做某事是……的”,这里的动词不定式“to learn English well”是真正的主语,“it”是形式主语。
“for”在这里表示“对……来说”。
选项B“of”一般用于表示人的品质的形容词,如“kind, nice”等,这里“important”不是描述人的品质,所以不能用“of”;选项C“with”不符合这个结构的用法;选项D“to”单独使用在这里是错误的。
3. We decided ______ a party for our teacher's birthday.A. haveB. to haveC. havingD. had答案解析:B。
“decide to do sth.”是固定搭配,表示“决定做某事”,这里动词不定式“to have”作宾语,表示决定要做的事情。
选项A“have”是动词原形,不能直接用在“decide”后面;选项C“having”是现在分词形式,不符合这个结构;选项D“had”是过去式和过去分词形式,也不适合这里。

本文可编辑可修改,如果觉得对您有帮助请收藏以便随时查阅,最后祝您生活愉快业绩进步,以下为初中英语动词不定式用法梳理及练习题的全部内容。
初中英语动词不定式用法动词不定式是由“不定式符号to+动词原形”构成的一种非谓语动词结构。
有些动词不定式不带to,动词不定式可以作句子的主语、表语、宾语、定语、补语、状语或单独使用.不定式保留动词的某些特性,可以有自己的宾语、状语等。
动词不定式和它后面的宾语、状语等一起构成短语,叫作不定式短语.一、用作主语直接把动词不定式置于句首的情况不多,多数情况用it作形式主语,把真正的主语-—动词不定式置于句末,特别是不定式短语较长时。
动词不定式作主语,谓语动词用第三人称单数形式.带疑问词的不定式短语作主语常置于句首,复合不定式结构作主语常置于句末。
如:1. I t is our duty to try our best to deal with these problems。
2。
The head teacher said it was necessary to talk with his mother.3。
How to learn English well is important.4.To see is to believe.(眼见为实;百闻不如一见)二、用作表语动词不定式作表语,常说明主语的内容、性质、特征。
如: 1.The best way is to join an English club。
2.The first thing is to listen to the teacher carefully.三、用作宾语1.可以接带to的动词不定式作宾语的动词主要有:要求选择同意(ask, choose, agree),期望决定学习(expect, hope, decide, learn),宁可假装知道(prefer, pretend, know),希望想要愿意(wish, want, would like / love)。
动词不定式用法与专项练习 2 动词不定式: to+do (高二2016.2) 动词不定式由 “to + 动词原形”组成,是动词的一种非谓语形式。动词不定式在句中可充当主语、表语、宾语、定语、状语、宾补、主补。 1. 动词不定式在句中的语法功能: (1)动词不定式(短语)作主语 To love is to be loved. 爱别人就是被人爱。 To teach is to give. 教书就是奉献。 *to do和v-ing作主语时的区别: Smoking is a bad habit. (v-ing作主语表示习惯性动作) To stay home on such a cold night is comfortable. (动词不定式作主语表示偶然性或一次性的动作) *不定式作主语和目的状语时的区别。例如: To get up early does good to one’s health.早起对身体有好处。(作主语) To get up early, one must go to bed early.为了早起,必须早睡。(作目的状语)
(2) 动词不定式(短语)作宾语 I will leave it to you to make the final decision. 我将由你来做最后的决定。(it作形式宾语) She decided to quit her job at last. 最后,她决定辞职。 *"疑问词 + 动词不定式短语"作宾语: I don't know what to do. 我不知道该怎么办。 The children are learning how to play the game. 孩子们在学做游戏。 例如(NMET2000):I’ve worked with children before, so I know what ____ in my new job. A. expected B. to expect C. to be expecting D. expects (答案:B) (what to expect在句中作know的宾语,而what作不定式to expect的逻辑宾语。) (四川09) He told us whether _______ a picnic was still under discussion. A. to have B. having C. have D. had (答案: A) 又如:It is said that in Australia there is more land than the government knows ____. A. it what to do with B. what to do it with C. what to do with it D. to do what with it 答案是C。what to do with it作knows的宾语。 *注意:有些动词后面必须跟动名词作宾语,平时要注意区别,进行区分。 *forget, remember, try, regret, mean, stop等动词后既可跟不定式又可跟动名词,须根据其习惯用法和语境进行取舍。例如(MET91): — The light in the office is still on.— Oh, I forgot____. A. turning it off B. turn it off C. to turn it off D. having turned it off 答案是C。forget to do意为“忘了做(某事)”,forget doing“忘了做过(某事)”; remember有类似的区别。类似的还有:try to do“尽力做”,try doing“试着做”;regret to say /tell“很遗憾地说”,regret doing“后悔做了……”;mean to do“意欲/ 想要做”,mean doing“意味着做”;stop to do“停下来做另外的事情”,stop doing“停止正在做的事情”。 3 4
The meeting being held is important. (表示动作正在进行当中) The meeting to be held is important. (表示动作将要发生)
注意: 1)当被修饰的是不定代词如everything, anything, much, little等,或被修饰的名词前被形容词最高级,序数词,the only等强调结构修饰时,非谓语动词作定语则用动词不定式。 Do you have anything to say? 你有什么要说的吗? I am afraid I cannot attend your party, for I have too many things to do. He is the only person to know the truth. 他是唯一了解真相的人。 When the question was out, he was the first one to raise his hand….他第一个举起手。 He was the last to realize the importance of this problem.
2)如被修饰的名词或代词是动词不定式的逻辑宾语,且动词不定式的动词是不及物动词,则后面需跟成为搭配的介词。 Who is the man to talk to? 要谈话的人是谁? He is a tough teacher to deal with. 他是个很难对付的老师。 I need a pen to write with. 我需要一支笔写字 例如:To fetch water before breakfast seemed to me a rule_____.(上海高考题98): A. to never break B. never to be broken C. never to have broken D. never to be breaking 答案是B,在句中作定语;由于a rule是不定式的逻辑宾语,所以不定式用了被动结构。 又如:There are five pairs____, but I’m at a loss which to buy. (上海高考题99) A. to be chosen B. to choose from C. to choose D. for choosing 答案是B,这是“不定式 + 介词”作定语。题意是“从五双中选一双”,故须在choose后加上介词from。类似的如a chair to sit in, a pen to write with, a topic to talk about等。
(6) 动词不定式(短语)作状语 动词不定式(短语)作状语可以表示目的,结果,原因等。 ▲ 目的状语 The whole family came out to see my performance. 全家人出来看我表演。 He called to say goodbye. 他打电话来道别。 ▲ 结果状语 We rushed to the railway station only to find (表示出乎意料) the train had just left. 我们匆匆赶到火车站,结果发现火车刚刚离开了。 He studied hard only to fail. 他学习很努力,但却没及格。 She went to South China five years ago, never to return.她五年前去了华南,结果从未返回。 *注意:doing也可以作结果状语,但表示自然而然的结果。 His parents were killed in the accident, making him an orphan. They all left, leaving me alone. ▲ 原因状语 动词不定式(短语)常跟在一些形容词后面,说明产生这些情绪的原因。这类形容词有:happy, ashamed, surprised, grieved, frightened, sorry, glad, delighted, eager, 5
disappointed, right, excited, ready, clever, bored等。 I am sorry to interrupt you. The father was surprised to learn that his son spent money like water. 得知儿子花钱如流水,父亲感到很吃惊。 We will be very happy to work on this project with you. 和您一起合作这个项目,我们感到很高兴。
(7) 动词不定式(短语)作独立成分 动词不定式(短语)可以用来作句子的独立成分。这些短语有:to begin with(首先), to tell the truth (truth to tell) (说实在的), to make a long story short(长话短说), so to speak(可以这么说), to be brief(简言之), to be exact(确切地说), to be frank (坦率地说), to do sb. justice(说句公道话), to conclude(总而言之)等。 To begin with, I'd like to introduce myself to you all. 首先,我想给你们作一下自我介绍。 To be frank with you, I don't love you any more. 老实对你说吧,我已经不再爱你了。 To conclude, energy is exhaustible, so we have to preserve it for our future generations. 总而言之,能量并不是用之不竭的,因此我们必须为后代保留一些。
2. 动词不定式中原形动词的省略 为避免重复,有时可用不定式的符号to来代表动词不定式。 -Would you like to have some coffee? 您要来点咖啡吗? -Yes, I'd like to. If you don't want to buy it, you don't need to. 假如你不想买的话,你就不要买。 注意:可以这样省略主要动词的动词不定式结构有:hope to, agree to, be willing to, want to, refuse to, fail to, manage to, would like to, offer to等。 ---What’s the matter with Della? --- Well, her parents wouldn’t allow her to go to the party, but she still ______.
