初中英语动词不定式及练习题
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.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)｡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.begin用了进行时态,后面只接不定式作宾语,表示事情刚开始,还要继续下去｡3) I like to eat vegetables.感知动词like, love, know等一般不用进行时态｡5.后接动词不定式或ving形式作宾语,意思差别较大的动词有forget, remember等｡后接不定式作宾语,表动作尚未发生;后接ving形式作宾语,表动作已经发生｡stop to do停下来做另外一件事,to do是目的状语;stop doing停止做､不做当前这件事，doing是宾语。

动词不定式用法全解(含测试题及答案)
动词不定式用法全解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。
动词不定式的形式：第一部分动词不定式的时态一、动词不定式的时态：动词不定式不能在句中作谓语，尽管它本身有时态的变化，但是却不能靠自身的变化形式表示动作发生的具体时间。
动词不定式发生的时间，一般只能根据谓语动词的时间，产生相对的先后时间关系。
1．不定式的一般式，表示不定式的动作与谓语动词动作几乎同时发生，或在谓语动作之后发生，或者不强调不定式动作的时间性。
但不定式表原因时，往往先于谓语动作之前发生。
如：The news will not fail to surprise him.这个消息将不会不使他大吃一惊的。
（不定式动作在将来和谓语动作同时发生）I helped to repair the car.我帮助修理汽车。
（不定式动作在过去与谓语动作同时发生）He didn't know where to go.他不知道该去哪儿。
（不定式稍晚于谓语动作）Tell your brother not to come tomorrow.告诉你哥哥明天不要来。
（不定式晚于谓语动作）判断：He decided to sell his car.I tried to go to school in time.I hope to see you soon不定式表示谓语动作的原因时，往往发生在谓语动作之前。
如：I am very happy to see you here.She seemed surprised to meet us.（先是遇见我们，她然后很吃惊）2．不定式的完成式，通常表示动作发生在谓语动词之前。
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能够省略。
动词不定式有实行体和完成体(如上to be writing，to have written)，也有被动态(如to be written)，所有的主动词，不管是及物动词还是不及物动词，也不管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，假如不定式较长，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，通常能够通过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，不定式后能够加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。

第十二章动词不定式(思维导图+知识梳理+好题精炼)2022-2023初中英语中考语法归纳
第十二章动词不定式思维导图知识梳理一、不定式概述动词不定式的基本形式是:“to+动词原形”,有时可以不带to.不带to的不定式与动词原形同形,但它不是原形,而是一种语法形式.除基本助动词do和情态动词外,英语动词都有不定式形式.动词不定式没有人称和数的变化,在句子中不能作谓语,但可以担任除谓语外的任何成分－主语、表语、宾语、定语、状语和宾语补足语.动词不定式和它的宾语或状语构成不定式短语.不定式有时态、语态变化(以do为例):主动语态被动语态一般式to do to be done进行式to be doing-完成式to have done to have been done 完成进行式to have been doing-动词不定式的句法作用(一)作主语用作主语的动词不定式通常表示一种具体的、特定的行为,其谓语动词用第三人称单数形式.To obey the laws is everyone's duty.服从法律是每个人的职责.How to use the computer is a question.怎么使用计算机是一个问题.How to get there is not decided yet.怎样去那里还没决定下来.点拨(1)在很多情况下,常用it作形式主语,而把真实主语不定式放在谓语之后.It was difficult to sell my car.我的车很难卖掉.It's not known where to stay for the night.在哪里过夜还不知道.(2)如果要表示不定式的动作是谁做的,一般在不定式前加一个for短语.It will be a regret for us not to help him.我们没有帮助他是个遗憾.(3)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,不定式前常可加一个以of引起的短语,来说明不定式指的是谁的情况.It would be rude of us to refuse their invitation.(我们)拒绝他们的邀请,会显得无礼.(二)作表语作表语,一般紧跟在系动词,如:be,seem,get等后面,用以说明主语.The question is when to start.问题是什么时候启程.You seem to have lost weight.你好像减肥了.What we have to do first is to find a solution.我们得做的第一件事是找出一个解决办法.点拨当不定式所作的表语仅用来说明主语的内容时,这个不定式只作单纯的表语,而不具有未来的含义.(三)作宾语能以不定式作宾语的动词很多,常见的有:agree,begin,decide,expect,forget,hope,learn,like,manage, pretend,start,try,want,wish等.Do you wish to see the manager?你想见经理吗?They decided to learn English hard.他们决定好好学英语.Don't forget to meet me at6:00.别忘了六点钟和我见面.有些动词,如:tell,advise,show,teach,know,forget,learn,remember,show,understand,see,wonder,hear, find out,explain,decide,discuss等后面,常用带疑问词的不定式作宾语.We don't know who(whom)to ask.我们不知道问谁.We asked how to get to the station.我们问怎么到达车站.Have you decided where to go for your holidays?你们决定到哪儿度假了吗?I don't know whether to apply for the job or not?那份工作我不知道申请还是不申请?(四)作定语I have no time to waste.我没有时间可浪费.Let me find a place to park.我来找个停车的地方.He is always the first to come to work and the last to leave.他总是第一个来上班,最后一个走.点拨不定式修饰something,anything,nothing时,放在它们的后面.如果something,anything,nothing有形容词来修饰,词序是something(nothing...)+形容词＋不定式.My father had something to do.我父亲有事要办.Have you got anything important to buy?你有什么重要的东西要买吗?(五)作状语不定式常可用作状语,修饰动词,表示行为的目的、结果、原因等.一般放在被修饰词之后,但在表示目的时,为了强调也可放在句首.1.作目的状语为加强语气在否定式前还可加上in order或so as组成词组(即:in order to...,so as to...),作状语表示目的.To live a long and healthy life,we must learn to have a balanced diet.为了能过长寿而健康的生活,我们必须懂得吃均衡的食品.I stayed there so as to see what would happen.我留在那儿,为的是想看看会发生什么事.In order to help him,we would do everything we can.为了帮助他,我们愿意尽一切力量.2.作结果状语表结果,其逻辑主语通常亦是全句的主语.在“so...as to...”“such...as to..“enough to...”“only to...”以及“too...to...”等结构中的不定式皆表示结果.She is old enough to go to school.她已到了可以上学的年龄了.He was too drunk to drive home.他酩酊大醉,没法开车回家.3.作原因状语She trembled to think of the terrible accident.想到那可怕的车祸,她就不寒而栗.We jumped with joy to hear the news.听到这消息,我们都高兴地跳了起来.(六)宾语补足语1、有很多动词的后面都可以有不定式作宾语补足语常见的这类动词有:advise,ask,tell,help,wish,want, expect,forbid,persuade,press,request,teach,warn等.She asked her grandfather to play game with her.她请爷爷跟她一起做游戏.Mother told me to cook the meal.妈妈叫我做饭.2.有一些动词后用作宾语补足语的不定式通常不带to,这种动词有两类:一类是感觉动词,另一类是使役动词感觉动词:如feel,see,hear,watch,notice等.使役动词:如make,let,have等.Let me do it for you.让我来替你做.Don't let her go out.别让她出去.I made him work hard.我迫使他加劲干.(1)动词help之后,复合宾语中的不定式可带to,亦可不带to.在上述动词转换为被动结构时,其后的不定式必须带to.He was seen to enter the theatre.有人看见他走进了剧院.I was made to do my homework the whole night.我被迫整晚做作业.Can you help me(to)move this table?你能帮我移动一下这张桌子吗?(2)感官动词的宾语补足语有两种形式:不带to的不定式和动词-ing形式.I heard Meimei singing in her room when I went past.我路过的时候听见梅梅在房间里唱歌.(路过的瞬间正在唱,所以用singing)We often hear Meimei sing in her room.我们经常听见梅梅在房间里唱歌.(经常听见,用不定式)I saw him come in.I saw him coming in.两句话的意思都一样:我看见他进来.用不定式着重于动作的全过程,用动词-ing形式则是强调当时动作的进行情况.3.当谓语动词为think,make,find,consider,feel,regard等词,作宾语的不定式后面有宾语补足语时,常用it作形式宾语,而将真正的宾语放在补足语的后面I find it easy to learn English well.我发现要把英语学好很容易.三、不定式的主要句型及注意事项(一)不定式的否定式不定式的否定式:not+不定式,经常和ask(tell)sb.to do sth.句型连用.She asked me not to drive him to the station.她要我不要开车送他到车站.Try not to be late.争取不要迟到.Mary asked me not to give my pen to Jimmy.玛丽让我别把笔给吉米.She decided not to come here again.她决定不再到这儿来.点拨不定式的否定式和否定句的区别:I asked him not to open the door.我让他别把门打开.I didn't ask him to open the door.我没让他把门打开.(二)不定式的进行时态进行式:表示在谓语动词所表示的动作或状态发生时正在进行.It's nice to be sitting here with you.在这儿陪你坐着是非常愉快的.It is unwise for him to be talking that topic all the time.他老是谈论这件事,很不明智.(三)不定式的完成时态完成式表示在谓语动词的动作或状态发生时已经完成.She said she was sorry to have missed you.她说她没见到你很遗憾.He seemed to have visited our factory.他好像参观过我们的工厂.They appeared to have met before.他们看来以前见过面.(四)动词不定式的被动语态表示被动意义I didn't want to be told about it.我不想被告知这件事.Nothing seems to have been forgotten.似乎什么也没有被遗忘.The building is said to have been destroyed in a fire two years ago.据说这幢大楼两年前已毁于一场大火.在以某些形容词,如kind,good,silly,honest,bad,stupid,bold,clever,cruel,courteous,nice,rude,sensible, tactful,wise,wrong等作表语时,后面需用以“of+名词(或代词宾格)＋不定式”结构,以说明不定式所表示的动作的执行者是谁(即of短语是不定式的逻辑主语).It's very good of you to come.谢谢你的光临.How silly of you(it is)to make such a mistake!你出了这样的差错,多傻啊！It's very kind of you to say so.多谢你这么说.在had better,had best,would rather,would rather...than,would sooner,would sooner...than,cannot but,do nothing but等结构后面的不定式要省略“to”.You had better write it in English.你最好用英文写.I would

初中英语语法-动词不定式专项练习
初中英语语法——动词不定式专项练习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．作主语动词不定式可以直接作主语。
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．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．或It is ＋n．（名词）＋to do sth．句型中，it仅作形式主语。
2．作宾语a．want，decide ，agree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。
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。
注意：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。
规律：上述动词后面接不定式和接动名词意思大不相同。
注意：1）stop to do sth．：停止一件事，去做另一件事。
初中英语语法专项：动词不定式用法(附练习答案)
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。
一．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 sthIt 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。

初中动词不定式专题讲解及练习(全面)
语法：动词不定式动词不定动式是一种非谓语动词形式，它没有人称和数的变化，在句子中不能作谓语，但可以作除谓语之外的其它任何句子成分（主语、表语、宾语、宾语补足语、定语和状语）；动词不定式具有名词、形容词和副词的特征，同时还保持动词的某些特点，既可以有自己的宾语和状语，动词不定式和它的宾语和状语构成不定式短语。
一、构成：to do .否定式not to do二、常见时态：一般时to do 进行时to be doing 完成式to have done完成进行式to have been doing三、动词不定式在句子中的成分1、作句子的主语：现实中常用it作形式主语，而把真正的主语动词不定式（或短语）后置。
比较下列句子To learn from your friends is important.=It is important to learn from your friends .To leave without saying goodbye is impolite.= It is impolite to leave without saying goodbye.To chat with Miss White is a pleasant thing.=It is a pleasant thing to chat with Miss White.To walk to school takes me ten minutes.=It takes me ten minutes to walk to school.句型总结●It is + adj. + of sb. to do…= sb. is\are +adj. +to do…在以某些表示人的品质、特征等的形容词（如kind、good、nice、wrong、clever、right等）作表语时，不定式之前常加一个引起的短语，说明不定式指的是谁的情况（可以理解为某人的好，坏，聪明，愚蠢，对，错等等）。

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 car2)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..begin用了进行时态，后面只接不定式作宾语，表示事情刚开始，还要继续下去。
3) I like to eat vegetables.感知动词like, love, know等一般不用进行时态。
5.后接动词不定式或ving形式作宾语，意思差别较大的动词有forget, remember 等。
后接不定式作宾语，表动作尚未发生；后接ving形式作宾语，表动作已经发生。
stop to do停下来做另外一件事，to do是目的状语；stop doing停止做、不做当前这件事，doing是宾语。
try to do尽力做，try doing试试看；go on to do 接着做另外的事，go on doing继续做原来的事。
如：1)When I left home, I forgot to bring it with me. 2)I stopped using them last year.—四、用作定语1.句子的主语或宾语是动词不定式的逻辑主语，不定式与其所修饰的名词、代词等存在逻辑的动宾关系.1)I have so many clothes to wash today.2)I can’t think of any good advice to give her. 3)We have no houses to live in.2.动词不定式所修饰的名词是place, time, way等时，不定式与这些名词呈现出动状关系或同位关系。
如：1)He needs time to do homework.·2) He wants to know the best way to travel around the city.3.在“there be...”句型里，句子的主语是动词不定式动作的对象：1)There’s just so much to see and do here.2)... but there are still many things to do there.五、用作宾语补足语>1.带to的动词不定式作宾语补足语的动词主要有：要求允许提议(ask, allow, , advise)，期望邀请鼓励(expect, , invite, encourage)，教导告诉想要(teach, tell, want)，等待希望愿意(wait for, wish, would like / love)。
如：1)Id invite her to have dinner at my house.2 We should allow the children to choose their own clothes.2.动词不定式作补语，在主动语态句里不带to，被动语态句里带to时多数动词是感官动词和使役动词，包括四“看”：look at, observe, see, watch，三“让”：have, let, make，二“听”：hear, listen to，一“感觉”：feel，一“注意”：notice。
如：1)This picture makes me feel excited！2)We saw Liu Yu play baseball last week.。
后接动词不定式作补语，to可带可不带。
1) they can help you to learn English. 2)Using email English helps you write quickly.六、用作状语1.目的状语，置于句首或句末，置于句首时常表示强调。
如：1)In order to catch the early bus, she got up very early.|2)A group of young people got together to discuss this question.3)She came to this city to visit her daughter.2.原因状语，多见于“sb.+be+adj.+to do...”结构句中。
如：1) I feel very lucky to have him.2) he ran out of money to buy old bikes.;3.结果状语，多见于“too...to”，“enough to...”结构句中。
如：1) I’m too tired to do it well.2)The room is big enough for three people to live in.七、动词不定式的复合结构动词不定式的复合结构是“for / of sb. to do sth.”，for / of引出不定式动作的逻辑主语。
这种结构在句子中可以作主语、宾语、表语、定语、状语等。
不定式复合结构的介词用for还是of，主要决定于前面形容词的性质。
一般说来，of 前面的形容词是careful, clever, foolish, good, kind, nice, wise等，既说明人的特性，又说明不定式动作的特性。
for前面的形容词是dangerous, difficult, easy, hard, heavy, important, interesting, necessary等，一般说明不定式动作的特性，前面如果是名词用for。
如：)’s a good idea for parents to allow children to study in groups during the evening. ’s wise of him to do it well.3)Is it interesting for the baby to play with a pet dog八、带疑问词的不定式短语动词不定式前面可以带疑问代词what, which, who或疑问副词how, when, where, why等。
这种结构起名词的作用，在句子里用作宾语、主语、表语等，或者单独使用。
要注意的是，why后面的不定式不带to。
如：1.用作句子的成分。
￥1)I don’t know what to try next. (作宾语)2)Where to go is not decided yet.(作主语)2.单独使用时相当于一个特殊疑问句。
1)What to do next(=What will we / you do next2)Why go there(=Why do we / you go there'九、动词不定式的否定式不定式的否定式是not / never to do...，不带to的不定式的否定式是not / never do...如：decide not to talk to each other.parents tell him never to play soccer in the street.单项选择：$（）1. The teacher told them ________ make so much noise.A. don’tB. notC. will notD. not to（）2. My mother often tells me _______so many mistakes.A. not to makeB. to not makeC. do n’t makeD. not make（）3.
