动词不定式用法与专项练习
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 c hildren 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”。
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,
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 ______. （江苏09）
A. hopes to
B. hopes so
C. hopes not
D. hopes for （答案：A）
一般而言，在否定结构中to必须保留。例如（NMET95）：
The boy wanted to ride his bicycle in the street, but his mother told him _____.
A. not to
B. not to do
C. not do it
D. do not to （答案：A）
3. 动词不定式的否定式: not必须置于整个不定式结构之前。
We decided not to go there. 我们决定不去那儿了。
I wished never to see him again. 我希望永不再见到她。
4．动词不定式的时态和语态
时态
▲动词不定式的一般式: to do: 表示的动作与谓语动词的动作是同时发生或将在其后发生的。
They are learning to sing and dance.他们在学习歌舞。
We have to get some money to buy a TV set. 我们得赚些钱来买台电视机。
▲动词不定式的进行式: to be doing: 表示的动作是与谓语动词的动作同时发生的，而且正在进行中。该结构也常与always, constantly, rapidly, fast, slowly等副词连用。The weather seems to be improving. 天气似乎在好转。
Come on, it's time to be making for (前往,走向) school. 好了，是上学的时候了。
He pretended to be reading when the teacher came in.
▲动词不定式的完成式: to have done: 表示的动作发生在谓语的动作之前。不定式的完成式常用在be said, be reported, be considered, appear, hope, pretend, seem等以及某些情态动词后，表示对过去事情的推断或虚拟假设，例如（NMET97）：I would love____ to the party last night but I had to work extra hours to finish a report.
A. to go
B. to have gone
C. going
D. having gone
答案是B，表示与过去事实相反的虚拟愿望。
He was said to have studied abroad for years. 据说他已经在外国留学多年了。
I am sorry to have kept you waiting. 很抱歉让你久等了。
He pretended not to have seen me when passing by yesterday.
他昨天从我身边经过时假装没看到我。
语态
▲不定式的被动式: to be done
如：He asked to be sent to the front. (他请求被派往前线。)
I wish to be excused. 我请求原谅。
This infectious disease is said to have been wiped out many years ago. 这传染病据说好多年前就已经灭绝了。
Having a trip abroad is certainly good for the old couple, but it remains ____ whether they will enjoy it.
A. to see
B. to be seen
C. seeing
D. seen
答案是B。因为不定式的逻辑主语it（指出国旅游这件事）与不定式是被动关系。Little Tom would love____ to the theatre this evening. (NMET’92）
A. to be taken
B. to take
C. being taken
D. taking (答案A)
It’s important for the figures _______ regularly. （北京2011）
A. to be updated

C. to update
D. to have updated (答案: A)
He claimed（声称）____ in the supermarket when he was doing shopping yesterday. A. being badly treated B. treating badly C. to be treated badly D. to have been badly treated
根据题意，该用不定式的完成被动式，表动作发生在claimed之前，故答案是D。
***值得注意的是，在下列场合通常用不定式的主动式表被动意义：
▲主语+be +形容词+动词不定式
当作表语的某些形容词被动词不定式修饰时，动词不定式与句子主语之间存在着逻辑上的动宾关系，动词不定式可以用主动式代替被动式。(阅P1)
This problem is difficult to solve. 这个问题很难解决。
▲ there + be句型中,动词不定式用主动式来表示被动的含义。
There are a lot of people (for me) to visit. There is no time to lose. 没有时间可以耽误。
▲“have + 宾语+ 动词不定式（作定语）”结构中
当have 表示"有"，而动词不定式与宾语之间存在着逻辑上的动宾关系，并且句子的主语是动词不定式动作的执行者时，动词不定式一般用主动式。
I have a lot of meetings to attend this week. 本周我有许多会议要参加。
▲在“too… to”, “… enough to”结构中，动词不定式总是用主动语态。
This problem is too easy to deal with. 这个问题处理起来很简单。
This problem is easy enough to deal with. 这个问题处理起来很简单。

高中英语动词不定式用法大全
高中英语动词不定式用法大全(名师总结必考语法知识点，值得下载) 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 pla nt 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。 Her ambition is to be a doctor. 她的理想是当医生。 三. 作宾语 动词不定式（短语）可以放在一些动词后面用作宾语，能以动词不定式作宾语的动词有：begin, start, want, forget, remember, show, learn, like, hate, love, ask等。例： I want to tell you a story. 我想给你讲个故事。 They begin to work at eight every morning. 他们每天早晨8点开始工作。 Don’t forget to lock the door.别忘了锁门。 Would you like to go and have a picnic with us tomorrow?明天和我们一
动词不定式的用法有哪些
动词不定式的用法有哪些？ 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: 一、不定式结构 1. 带to的不定式结构能直接跟带to的不定式结构的动词主要有：want, expect,plan,begin,start,ask, tell, hope, learn, try, decide, forget, remember, like, love, stop, go, come等。 如：I want to go to the movies with you. 我想跟你一起去看电影。 Don’t forget to turn off the light before you leave. 在你离开之前别忘了关灯。 注意：动词不定式的否定形式是在不定式前直接加not，即not to do sth.。 如：Dave told me not to wake up Kate. 大卫告诉我别叫醒凯特。 2. 不定式有时和一连接代（副）词一起构成宾语。 如：I don’t know what to say.我不知道说什么。 3. 不带to的不定式结构以下几种情况使用不带to的动词不定式： （1）在固定词组had better之后。注意：had better的否定形式是had better not do sth.。 如：You had better go home now. 你最好现在回家。 It’s cold outside. You’d better not go out. 外面很冷，你最好不要出去。 （2）在let, make, see, feel, watch, hear,have等感官或使役动词后，要跟不带to的动词不定式作宾语补足语。 如：I made them give me the money back. 我迫使他们把钱还给我。 I didn’t see y ou come in. 我没看见你进来。 （3）在引导疑问句的why not之后。Why not+不带to的不定式是Why don’t you do的省略，可以用来提出建议或劝告。 如：Why not take a holiday?=Why don’t you take a holiday？ 为什么不休个假呢? （4）不定式动词在介词but, except, besides后面时，如这些介词前有实义动词do的各种形式，则后接不带to的不定式，否则带to。 如：I have no choice but to accept the fact. 除了接受这个事实我别无选择。What do you like to do besides swim? 除了游泳你还喜欢做什么？ （5）为了避免重复，不定式可省去to。 如：I’m really puzzled what to think or say. 对于想什么或说什么，我真

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。 Her ambition is to be a doctor. 她的理想是当医生。 三. 作宾语 动词不定式（短语）可以放在一些动词后面用作宾语，能以动词不定式作宾语的动词有：begin, start, want, forget, remember, show, learn, like, hate, love, ask等。例： I want to tell you a story. 我想给你讲个故事。 They begin to work at eight every morning. 他们每天早晨8点开始工作。 Don’t forget to lock the door.别忘了锁门。 Would you like to go and have a picnic with us tomorrow?明天和我们一

动词不定式的精讲与专项练习
动词不定式（The Infinitive） 一、概述 不定式是动词的一种非谓语形式，在句中不能单独作谓语。它有两种形式：（1）带to的不定式；（2）不带to的不定式（即通常所说的动词原形），它可以和助动词或情态动词构成谓语。不定式既有动词性质，又有名词性质。 1）不等式具有动词性质，即它有时态和语态的变化；可有自己的宾语或状语并构成不等式短语。如： Would you like to tell me an interesting story? 你可不可以给我讲一个有趣的故事？（不等式to tell有自己的宾语me和story）He was too clever a man to be fooled.他这个人很机灵，不会被愚弄的。（不等式的被动语态） I’m going to go there by bike. 我想骑自行车去那儿。（不定式有状语there） They will set up more primary schools in the countryside. 他们将在乡村修建更多的小学。（不带to的不等式与助动词will一起构成谓语）但是，不等式没有人称和数的变化，即不受人称和单数、复数的限定或影响。 She likes to play the accordion. 她喜欢弹奏手风琴。 She liked to play the accordion when she was young. 她很小就喜欢弹奏手风琴。 2）不等式具有名词性质，即它在句中可用作主语、宾语、表语等。如： To see is to believe. 百闻不如一见。（作主语） This suit doesn’t seem to fit me.这件衣服似乎不适合我穿。（作表语） She wanted to see which shops offered the best service. 她想看看哪家商店提供最好的服务。（作宾语） There’s no need to be worried. 不需要担心。（作定语） He went there to see what would happen.他去那儿是想看看会出什么事。（作状语） 3）不等式虽然在语法上不能有主语，但它表示的动作，在意思上是可以有自己的主语，在语法上这个主语称为不等式的逻辑主语。这个逻辑主语可能是整个句子的主语、宾语等，也可以用一个由for引起的短语表示。如： His friends tried to encourage him. 他的朋友设法鼓励他。（不等式的逻辑主语His friends同时也是句子的主语） Every year, tobacco companies must persuade new people to start smoking cigarettes. 每年烟草公司要设法使一些比吸烟的人开始吸烟。（不等式的逻辑主语new people是句子的宾语）It’s very difficult for a foreigner to learn Chines e. 外国人学汉语是很不容易的。（不等式的逻辑主语由for引起的短语表示） 另外，不等式的否定形式一般在它的前面直接加not或never。 The teacher has told me many times not to come late again.老师多次告诉我不要再来晚了。 She seems not to have a bright time with her new friends.和新朋友在一起她似乎过得不是太好。 二、不定式的主要用法 动词不等式具有名词、形容词及副词的特征，因此在句中可作主语、宾语、宾语（或主语）补足语、表语、定语、及状语等。 1、不定式作主语 ①不等式作主语时，谓语动词用单数形式。 To conquer English is not easy. 征服英语不容易。 To make plan firs t is a good idea. 先制定计划是个好主意。 To know everything is to know nothing. 事事皆通，无一精通。 ②不等式作主语时，常常用形式主语it替代，而将真正的主语不等式放在句子的后面。 It is necessary to master a foreign language.掌握一门外语很有必要。 It’s a great pleasure to see you again.再次见到你真高兴。 It is a bad manner to stare at a foreign guest.盯着外宾看是一种不良的举动。 ③如果说明不等式表示的动作是谁做的，可以在不等式的前面加一个for引起的短语，这就是常见的“It is adj./n. for sb. to do sth.”句式。如： It is good manners for an Arab to stand close to his friends when they are talking. 对阿拉伯人来说，交谈时站得离朋友近些是好的礼貌。 It is a great honor for us to be presented at the party.我们能来参加晚会，深感荣幸。 It will be a regret for us not to help him. 我们没有帮助他是个遗憾。 ④在某些形容词（如kind, good, nice, wise, unwise, clever, silly, wrong, right, foolish, stupid, careless, considerate, rude, naughty, impolite等）作表语时，不等式前常加一个以of引起的短语，来说明不等式指的是谁的情况。这就是常见的 “It is adj. of sb to do sth.”句式。如：

动词不定式讲解、专项练习及答案
初中英语语法（动词不定式） 1．不定式的基本形式与结构 动词不定式指通常由to加上动词原形(如to write) 所构成的一种非限定性动 词形式，但在有些情况下to可以省略。动词不定式有进行体和完成体(如上to be writing，to have written)，也有被动态(如to be written)，所有的主动词，不论是 及物动词还是不及物动词，也不论是动作动词还是状态动词，都有不定式形式。 助动词除be和have外，没有不定式形式。动词不定式在语法功能上可作主语、 宾语、表语、定语和状语。 2．不定式的用法 1)不定式结构作主语 1.Te get contact with his family in Taiwan made him extremely happy since they separated more than 40 years ago． 2.To finish that task in such a short time is really a challenge． 在上述情况下，如果不定式较长，显得头重脚轻，则可由代词让作形式主语(形式主语it不可由that或this等其他代词代替)，而将不定式放到后面。如： 1.It made him extremely happy to get contact with his family in Taiwan since they separated more than 40 years ago． 2.John admitted that it is always difficult for him to be on time． 不定式结构所表示的动作是谁做的，即不定式的逻辑主语，通常可以通过for sb. to do sth. 结构表达： 1.It is quite important for us to read good books during a general review． 2.It is not difficult fot those talented students to pass the exam. 在某些形容词(如careless，clever，considerate，foolish，good，impolite，kind，naughty，nice，silly，stupid等)作表语时，不定式后可以加of来引导出其逻辑主语： 1.It is very kind of you to tell me the truth． 2.It is stupid of him to do such a silly thing． 2)不定式作宾语 不定式作宾语有两种：一种是及物动词后直接跟带to的不定式，另一种是“及物动词+疑问词+带to的不定式。 及物动词+带to的不定式结构: 只能跟动词不定式的动词，常见的有: afford，agree，aim，appear，ask，believe，care，claim，decide demand，desire，determine，expect，fail，happen，hesitate，hope，intend，learn，long，manage，offer，pretend，promise，prepare，refuse，seek，swear，undertake，want，wish等。 1.He managed to solve the complicated problem. 2.The stranger offered to show me the way. 3.Mr. Smith undertook to build a new plant in South Africa. 动词+疑问代(副)词+不定式： 这类动词常见的有advise，decide，find out，forget，inquire，know，learn，

动词不定式讲解
动词不定式的用法 概念： 动词不定式由to+动词原形构成。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的特点及作用。可以做主语、宾语、宾语补足语、表语、定语、状语。 一、作主语 动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种： (1)把不定式置于句首。如： To get there by bike will take us half an hour. (2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。如： ①It＋be＋名词＋to do It's our duty to take good care of the old. ②It takes sb+some time+to do How long did it take you to finish the work ③It＋be＋形容词＋for sb＋to do It is difficult for us to finish writing the composition in a quarter of an hour. 在句型③中，常用表示客观情况的形容词，如： easy, difficult, hard, important, possible, impossible, comfortable, necessary, better; the first, the next, the last, the best, too much, too little, not enough ④It＋be＋形容词＋of sb＋to do It is stupid of you to write down everything the teacher says. 在句型④中，常用 careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise rude, clever, foolish, thoughtful, thoughtless（欠考虑的；不考虑的）, brave, considerate(考虑周到的), selfish(自私的)等表示赞扬或批评的词。在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is＋形容词＋to do句式，如：It's kind of you to help me with my English.=You are kind to help me with my English. ⑤It seems(appears)＋形容词＋to do It seemed impossible to save money. It seemed selfish of him not to give them anything. 他不给他们任何东西，这显得太自私了。 注意：1) 其他系动词如，look，appear等也可用于此句型 2) 不定式作为句子主语时，动词用单数形式。 3) 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 对应性：To see is to believe. 百闻不如一见。 二、作宾语 1) 以下动词后，只能跟不定式作宾语 afford （付得起），agree（同意），aim(力求做到), appear（显得），arrange（安排），ask（要求），attempt （试图），care（想要），choose（决定），claim（声称），condescend （屈尊），consent（准许），decide（决定），demand（要求），determine（决心），endeavor （竭力），expect（期待），fail（未履行），help（帮助），hesitate（犹豫），hope（希望），learn（学会），manage（设法），neglect（疏忽），offer（主动提出），plan（计划），prepare （准备），pretend（假装），proceed（接着做），promise（答应），prove（证明），refuse （拒绝），resolve（解决），seem（觉得好像），swear（发誓），tend（往往会），threaten （威胁），undertake（承诺），volunteer（自愿做），vow（发誓），want（想要），wish（希
