初中英语语法精讲动词不定式用法(教案)精编版
动词不定式用法
动词不定式没有人称和数的变化，在句中不能独立作谓语。但动词不定式具有名词、形容词和副词特征，在句中可以作主语、宾语、宾语补足语、定语、表语和状语等多种成分。另外，动词不定式具有动词特点，可以有自己的宾语和状语，组成动词不定式短语。动词不定式的肯定形式是to＋do；其否定形式是not to＋do。
下面以动词不定式在句中的作用来予以详细说明。
1．作主语
可以直接作主语。如：To see is to believe．
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．
It's our duty to keep our environment clean and tidy．
点击规律：动词不定式在句中作主语时，常放在It is ＋adj +(for sb.)＋(not)to do sth句型中，表示说话人对客观事件的决断，意为：做…..是……的，it仅作形式主语，真正的主语是to do sth
It is very interesting to read.读书是有趣的
It is useful to read.看书是有用的
It is healthy to run every day.每天跑步是健康的
It is a little difficulty for me to work out this question.解出这道题对我来说有点难
It is bad not to finish homework.不完成作业是糟糕的
It is bad to be late for school.迟到是糟糕的
It is+adj+of sb +(not)to do sth该句型通常表示说话人对客观事件的惊讶、兴奋、懊悔、难过等感叹情绪，与It is ＋adj +(for sb.)＋(not)to do sth的意义不同。
It is very kind of you to tell me the truth．你能告诉我事实，真是太好了
It is stupid of him to do such a silly thing．他做那件傻事，真是太笨了
It is very clever of you to work out this question. 你能解出这道题目，真是太聪明了
It is very wise of you to read this novel. 你看这本小说，真是太明智了
这个句型中用介词of而不是for的原因是这里的形容词是用来形容人的品质性格的。
类似的词有：careless，careful，clever，considerate，foolish，good，impolite，kind，naughty，nice，silly，stupid，friendly
因此区分是用It is ＋adj +(for sb.)＋(not)to do sth还是It is+adj+of sb +(not)to do sth，要
清楚adj修饰的是sb还是to do sth
例如：It is nice for me to have breakfast with you（nice是指have breakfast with you这件事）对于我来说，能和你一起吃早餐真好。
It is nice of you to help him with his English.（nice是指you，形容人的品质）你帮他补习英语，真是太好了。
2．作宾语
a．want，decide ，agree，afford，agree，aim，appear，ask，believe，care，claim，decide ，demand，desire，determine，expect，fail，happen，hesitate，hope，intend （有打算），learn，long（渴望），manage，offer，pretend，promise，prepare，refuse，seek，swear（发誓），undertake（承担），want，wish等动词后面跟并且只能跟不定式。如：
We agreed to start early．
She wants to be a doctor．
b．love，like ，begin，start，hate ，prefer等词后面可以接不定式。
点击规律：上述动词后面除接不定式外，还可以接动名词，意思无很大区别。
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．我喜欢游泳，但我现在不想游。
c．stop，forget，remember，go on ，try等词或短语后面可以接不定式。
点击规律：上述动词后面接不定式和接动名词意思大不相同。
提示板：
1）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。
2）forget to do sth：忘记要去做某事（未做）
forget doing sth：忘记做过某事（已做）
3）remember to do sth：记得去做某事（未做）
remember doing sth：记得做过某事（已做）
4）go on to do sth：接着做另一件事（接下去做与原来不同的一件事）
go on doing sth：继续不停的做某事或间断后继续做原来没有做完的事5）try to do sth：试着做某事（实际上意思是努力想做成某事eg:I tried to escape,but I failed.我努力着想逃走，但是没有成功）
Try doing sth：试着做某事（实际上是为了达到另外一个目的，-------"So hot here,isn't it?" -------"Yes,why not try turning on the air conditioner?" "很热，是吧。" “恩，就是。咱们开开空调吧，看看能不能凉快点儿。”）
例句：When the teacher came in，the students stopped talking；when he came out，the students stopped to talk．当老师走进来时，学生们停止说话；当老师走出去时，学生们又开始说话。
d．在find／feel＋it＋adj．＋to do sth．句型中，it是形式宾语，真正的宾语是后面的动词不定式。就是说不定式由it代替，把不定式放到后面去。这可以用这一结构表达：动词(如find，think，consider，feel等)+it+ 形容词+不定式。如：
She considers it necessary to make friends with him.
We find it difficult to finish all the homework before 9 o’clock.
The man downstairs found it difficult to get to sleep．
I feel it easy to recite the text．
e. 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，see，regard，remember，teach，tell，understand，wonder等。常见的疑问代(副)词有: what，when，where，which，how，whether等。
1.He does not know when to start.
2.You can decide whether to continue or to stop.
3.I will show you how to deal with it.
3．作宾语补足语
a．tell，ask，want，order，teach，invite，warn，wish，help，get，wish，help等词后面常接不定式作宾补。如：
I tell him not to go there by bus ．
Edison's mother taught him to read and write．
b．let，make，have，see，hear，feel，watch，notice后面接不带to的不定式作宾补。如：
The boss makes them work 16 hours a day．I heard her sing in the next room．
提示板：若变成被动语态，在上述结构中，不定式符号to要加上。如：
They are made to work 16 hours a day by the boss．
She was heard to sing in the next room．
4．作定语：放在被修饰的名词、代词后面
例句：I have a lot of work to do．
He could do nothing to help the boy．
There was really nothing to fear．
He gave me an interesting book to read
点击规律：动词不定式若在句中作定语，常放在被修饰的名词、代词之后。
提示板：如果动词不定式和前面所修饰的词构成动宾关系，若动词是不及物动词，切记不要忘掉介词。如：
I have a small bedroom to live in．
Have you got some pens to write with？
Mary needs a friend to play with．
That girl has nothing to worry about．
They have a strict teacher to listen to．
5．表语：放在连系动词be后面
例句：His wish is to become a scientist．
The first important thing is to save the soldiers' lives．
当务之急是抢救战士们的生命。
点击规律：动词不定式在句中作表语时，通常对连系动词前面的名词进行诠释说明。
6．作状语
a．目的状语：放在go，come，use，live，in order等词后面。如：
I come to see you．
He runs fast in order to get there in time．
b．原因状语：放在sorry，glad，surprised，disappointed，excited等词后面。如：
I am glad to see you here．
I am sorry to trouble you．
c．作结果状语。如：
Some of the apples are hard to reach．
The room is large enough to hold 1000 people．
7．与what，who，whose，when，where，how等疑问词连用，作宾语、宾语补足语、主语等。如：I don't know what to do next．（宾语）
He taught us how to use the computer．（宾语补足语）
It's still a question how to get there．（主语）
8、在动词help之后可用不带to的不定式，也可用带to的不定式。例如：
1.Help the old lady (to) carry the heavy box.
9、在had better，would rather，may／might as well，rather than，can not but等搭配之后初中英语语法总结，动词不定式也不带to。例如：
1.Unless you feel to ill to go out，I would rather not stay at home tonight．
2.She could not but criticize his foolish behaviour.
10.在介词but，except之后，如果其前有动词do的某种形式，其后不定式一般不带to，反之则必须带to，表示“只能”。例如：
1.He will do anything except work on the farm．
2.There was nothing left for the enemy to do but surrender．
3.The spy间谍was both hungry and cold；there was nothing left for him but to give in．
4.I had no choice but to wait till it stopped raining．

如果上述句中有do，to省略：
I did nothing but watch TV last night．
如果是下面一个固定搭配，就带to：
I have no choice but to give up my idea.
12、紧跟在why或why not之后的动词不定式总是不带to。但是，紧跟在who，what，which，whether等连接词后的不定式带to。例如：
Why stand up if you can sit down?
Why not ask your teacher when you don't understand the meaning?
You needn't decide whether to study arts or science．

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

It’s not polite of him to speak to old people like that. It is + adj. + for sb. to do…≠ sb. is\are +adj. +to do…如果要说明不定式表示的动作是谁做的，则在不定式前加一个for引起的短语，即不定式的逻辑主语。 It is necessary for us to study hard.

不带to的动词不定式讲课教案
不带to的动词不定式有哪些 不定式是英语动词的非限定形式之一，是英语中一种非常活跃的语言现象，不带to的不定式（bare infinitive）是我们学习、掌握和运用这一语法现象的难点。本文的目的就是要对不带to的不定式作一粗浅的探讨。首先要指出的是，不带to的不定式的使用实际上非常普遍，主要用在情态动词和助动词will，shall，would，should，can，could，may，might，must…以及在作为情态动词的need和dare之后。但因为这一点在学习英语的过程中极易掌握，故不在此赘述。除此以外，在下列情况下也要使用不带to的动词不定式。 1．在see，feel，hear，watch，observe，listen to，look at, notice等感官动词或短语以及let，have，make等表示祈使意义的动词后面；不定式作宾语补足语不能带to；help后面的不定式可以不带to，也可以保留to；know在一定的条件下，后面的不定式作宾语补足语时可以不带to。例如： I saw the man come out of the house． I heard her say that she was from Japan． We felt the house shake． They watched the sun sink into the sea． Did you notice him stop？ They did not observe Jim come in and go upstairs． She was listening to him climb the stairs． Look at the boy run！ I'll let you know as soon as I hear from her． I had him mend my watch． Electricity makes motors run． He helped me（to）plant trees． I have never known him sing so beautifully． 不带to的动词不定式跟在上述动词后面时，情况比较复杂，有以下几个问题须特别注意： （1）当上述句子变成被动语态时，原来作宾语补足语的不定式则相应地成为主语补足语。这时，不定式就一定要带to，以上述句子为例：
动词不定式的基本用法
动词不定式的基本用法 一、概述 动词不定式是一种非谓语动词形式，它能起名词、形容词和副词的作用，在句子中作主语、宾语、定语、表语、宾语补足语和状语。其形式如下：（主动形式） ◆一般式（not）to do 一般现在时表示的动词有时与谓语动词表示的动作同时发生，有时发生在谓语动词的动作之后。 He seems to know this. 我希望再见到你。_____________________________________________________ ◆完成式（not）to have done 完成时：表示的动作发生在谓语动词表示的动作之前。 He seems to have caught a cold. 很抱歉给你带来这么多的麻烦。____________________________________________ ◆进行式（not）to be doing 进行时：表示动作正在进行，与谓语动词表示的动作同时发生。 He seems to be eating something. 他假装在学习。_______________________________________________________________ 二、动词不定式的语法功能 （一）作宾语 1) 动词+ 不定式 The driver failed to see the other car in time. 司机没能及时看见另一辆车。 我碰巧知道你那道问题的答案。 ____________________________________________________________________ ★常用的动词有afford, aim, appear, agree, arrange, ask, decide, bother, care, choose, come, dare, demand, desire, determine, expect, hope, fail, happen, help, learn, long（渴望）, mean, manage, offer, ought, plan, prepare, pretend, promise, refuse, seem, tend, wish… 2）动词+疑问词+ to Please show us how to do that. 请演示给我们如何去做。
动词不定式的用法荟萃
动词不定式的用法荟萃 不定式在句子中可做主语、宾语、表语、定语、状语和宾语补语。 1)不定式做主语一般表示具体的某次动作。 【例如】 To complete the 30storied building in one year was quite a difficult task. To do that implies taking responsibility. 当主语较长，谓语较短时，常用it做形式主语，而将不定式放到 谓语的后面。 【例如】 It is important for modern young people to master at least two foreign languages. It做形式主语，不定式放在谓语动词之后常用于下列结构中： a) It is＋形容词(easy, important, difficult, foolish,
inconvenient, unnecessary, right, wrong...)＋( for/of sb.)＋ 不定式 【例如】 It is essential to reserve a table in advance of Christmas Eve. hard to put my hopessintoswords. It is not easy to catch fish with your hands only. It is important for us young people to learn English and master it. b) It is＋名词(a pleasure, a pity, a pleasant thing, one’s du ty, an honor, a shame, a crime, no easy job...) ＋不定式 It is a sheer waste of time to read that kind of trash. It is a pity to have to go without her. It is a glorious death to die for the people.

初中不定式todo的用法
1. 不定式的用法------1.1 不定式作主语 不定式作主语，往往用it作形式主语，真正的主语不定式放至句子的后面。 例如：It's so nice to hear your voice. 听到你的声音真高兴。 It's necessary for you to lock the car when you do not use it. 不用车的时候，锁车是有必要的。 It's very kind of you to help us. 他帮助我们，他真好。 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。 但是，用不定式作主语的句子中还有一个不定式作表语时，不能用It is… to…的句型。另外，这样的句子，不能用动名词作表语。例如： （对）To teach is to learn. （错）It is to learn to teach. （错）To teach is learning. （错）Teaching is to learn. 典型例题 The chair looks rather hard, but in fact it is very comfortable to ___. A. sit B. sit on C. be seat D. be sat on 答案：B. 如果不定式为不及物动词，其后应有必要的介词。当动词与介词连用时，常位于"形容词+动词不定式"结构的末尾。 1.1.1 不定式做主语It's for sb/It's of sb to do sth 这样的句子中，由于表语形容词性质的不同，导致了不定式逻辑主语标志用for或of 的区别。 1）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, interesting, impossible等：例如： It's very hard for him to study two languages. 对他来说学两门外语是很难的。

动词不定式用法及练习题-L105
动词不定式用法小结 动词不定式用法小结 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。 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 g ood 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： 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,

动词不定式教案 教学目标 1.学会什么是动词不定式 2.会使用动词不定式 重难点 1.能正确的使用动词不定式的各种用法 教学步骤 Grammar: 动词不定式 Ⅰ. 不定式句法功能 1. 作主语：The cat said, “To take roller coaster” is terrible. 不定式短语作主语时，可以直接放在句首，但在很多情况下，尤其是在疑问句和感叹句中，往往放在谓语之后，而用先行代词it作形式主语。 → The cat said, “It’s terrible to take roller coaster.” How long did it take you to take roller coaster? How terrible it is to take roller coaster? 不定式作主语常见句型： a) It is + adj. (easy, important, difficult…) + 不定式 b) It is + n. (a pity, a pleasure, one’s duty, a shame) + 不定式 eg. It’s my dut y to teach you how to be a student of No.3 Middle School. c) It takes/needs/requires + some time (hours, months, days, patience…) + 不定式 eg. It requires patience to be a good teacher. 2. 作表语：当句子的主语是aim, idea, policy, question, suggestion, wish, task, duty, job, purpose等或者主语是what引导的名词性从句时，后面可以用不定式做表语，用以说明主 语所包含内容。 eg. Our most important task now is to make a plan. 注：作表语的不定式都带to，但当主语部分有实义动词do时，to可以省略。 eg. The only thing we can do now is wait and see. 3.作宾语 The cat said “Remember not to take it next time!”. a) 可以直接用不定式作宾语的动词很多，常见的有：agree, afford, tend, ask, decide, determine, expect, fail, hope, learn, intend, manage, offer, plan, promise, refuse, want, wish等 I don’t want _____ like I’m speaking ill of anybody, but the manager’s plan is unfair.

We have no choice but to wait. Cf. We can do nothing but wait.

初中英语动词不定式用法梳理及练习题
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. ' head teacher said it was necessary to talk with his mother. to learn English well is important. 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： | best way is to join an English club. 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)。如： 1)We decided to talk to some students about why they go there. ~ 2)He prefers to eat white bread and rice. 3)Id love to visit Mexico. 2.动词decide, know, learn, show, teach, tell...，介词结构on...可用疑问词带to的不定式短语作宾语，但why后面的不定式不带to。如： 1)Could you please tell me where to park my car 2)It gives advice on what to do in lots of different situations. ： 3.动词feel, find, make, think等后面，可以用it作形式宾语代替真正的宾语——动词不定式，句子结构是...feel / find / make / ... it+adj. / n.+to do...。如： I find it difficult to remember everything. 4.既可接动词不定式又可接ving形式作宾语，意思差别不太大的动词有begin, start, like, love等。一般说来，动词不定式表一次、数次的具体动作、将来动作或动作的全过程，ving形式表习惯性的连续动作。但是这种区别并不很严格，特别是美国英语，即使是习惯性的动作也可以用动词不定式。如： 1) Then I started to watch Tv. 2) I am beginning to understand my parents. .

(完整版)动词不定式的用法总结
动词不定式的用法总结 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。接下来为大家提供了以下：动词不定式的用法总结一 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。 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, 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 you 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
