上面的句子可以改为：· It is hard to be a doctor. · It is not easy to learn English w ell. · 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。

动词不定式用法归纳全
动词不定式用法归纳全动词不定式这玩意儿，在英语学习里可算是个“常客”啦！今天咱们就来好好把它的用法捋一捋。
先来说说啥是动词不定式。
简单说，就是“to ＋动词原形”的形式，比如“to do”“to play”“to study”等等。
动词不定式在句子里的角色那可多了去了。
它能当主语，比如说“To learn English well is not easy” （学好英语不容易。
）这时候，它就像个带头的老大，引领着整个句子的意思。
当宾语的时候也不含糊，像“I want to go shopping” （我想去购物。
）“want”后面跟着的“to go shopping”就是宾语，表达了我心里想做的事儿。
还有当定语的时候，比如“There is nothing to worry about” （没什么可担心的。
）“to worry about”就是用来修饰“nothing”的。
当状语的时候呢，就像“He got up early to catch the first bus” （他早起是为了赶上第一班公交车。
）这里的“to catch the first bus”就是说明了他早起的目的。
再给您说个我教学时候的事儿。
有一次上课，我讲到动词不定式当宾语补足语的用法，就举了个例子“Tell him not to play in the street”（告诉他别在街上玩。
）然后我问同学们懂了没，结果有个小调皮眨着眼睛问我：“老师，那要是他非要在街上玩咋办？”全班哄堂大笑，我也乐了，然后耐心地跟他解释：“那可不行，这不仅危险，还不符合语法规则呀！”从那以后，这个知识点同学们记得特别牢。
咱们继续说，动词不定式还有一些固定的搭配和句型，像“It's ＋adj ＋ for/of sb to do sth” （对某人来说做某事是……的）“tooto” （太……而不能……）等等。
比如说“It's kind of you to help me” （你帮助我真是太好了。

3．作表语和宾语不足语
❖ 动词不定式作表语，一是主语有不定式充当；二是 主语由抽象名词充当。
To teach is to learn. My job is to help the patient. 【注意】如果在主语中（通常在主语从句或修饰主语 的定语从句中）又实意动词do时，作表语的动词不 定式省略to。 All I want to do now (What I want to do now) is fill my stomach.
I think it necessary to report the thing to the teacher.
I find it interesting to work with him.
C．动词不定式还可以用作介词宾语，但仅限于 介词except和but（除了）。 ❖常用句型有： There is nothing to do but+动词原形 do nothing but+动词（除做….之外别无选择） can but+动词原形 （只能原形(“只有做……) have no choice but to do ，只得） cannot help/choose but+动词原形(不能不……）

动词不定式用法归纳
动词不定式用法归纳●动词不定式的肯定形式是to＋do；其否定形式是not to＋do。

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。
●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。
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．规律：动词不定式在句中作主语时，it仅作形式主语。
如：It is ＋adj．（形容词）＋to do sth．或It is ＋n．（名词）＋to do sth．2.作宾语✓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．✓love，like ，begin，start，hate ，prefer等词后面可以接不定式，还可以接动名词，意思无很大区别。
提示：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。

但后面接不定式和接动名词意思大不相同。
如: 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。
比较：When the teacher came in，the students stopped talking；当老师走进来时，学生们停止说话；when he came out，the students stopped to talk．当老师走出去时，学生们又开始说话。

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:“t o+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 -(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 at 6:00.别忘了六点钟和我见面.有些动词,如:tell, advise, show, teach, know, forget, learn , remember,

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

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

动词不定式的归纳编写Johnplay Saturday, November 23, 2013动词不定式由to +动词原形组成,在句子中具有名词、形容词和副词的特征,因此在句中可以作主语、表语、宾语、定语、状语、宾补。
㈠不定式作主语动词不定式在作主语时,用法主要有以下几种：⑴动词不定式作主语时,常用it作形式主语,而往往将动词不定式放在谓语或表语之后。
如：①It's not easy to learn a foreign language well.=To learn a foreign language well is not easy.学好一门外语不容易。
②It is dangerous To lean out of the window=To lean out of the window is dangerous.身子探出窗外很危险。
⑵ It takes sb+some time+to do用it作形式主语,把真正的主语不定式置于句后。
如：①How long did it take you to finish the work? 你花了多少时间来完成这项工作吗？②It will take us half an hour to get there by bike 我们骑自行车到那里将要花半小时。
⑶It+be+形容词+for sb+to do，常用表示客观情况的形容词，如：difficult, easy, hard, important, impossible, necessary等.①It's difficult for us to finish the work. 对我们来说，完成这项工作很困难。
②It's hard for me to answer your question. 要我回答你的问题很难。
⑷It+be+形容词+of+ sb+to do常用careless, clever, good, foolish, honest, kind, lazy, nice, right, silly, stupid, wise等描述行为者的性格、品质的形容词,则应在不定式前加一个of引起的短语。
☻注意：在of sb.结构中,可用sb.直接作句子的主语来改写。
试比较：①It's foolish of him to go alone. (=He was foolish to go alone.) 他单独出去太傻了。
②It's kind of you to give me the book. (=You are kind to give me the book.)你给我这本书,真是太好了。
⑸It seems(appears)+形容词+to doIt seemed impossible to save money. 现在好像不可能存钱。
⑹It+be+名词+to doIt's our duty to take good care of the old.照顾老人是我们的责任。
⑺不定式的完成式也可作句子的主语①To have made the same mistake twice was unforgivable.两次犯同样的错误是不可原谅的。
②It is better to have loved and lost than never to have loved at all.爱过而后失去了爱,比从未爱过要好。
⑻疑问词who,which,when,where,what等常与不定式连用,在句中起名词作用,可充当主语、宾语、表语等。
①How to solve the problem is very important．(主语) 如何解决这一问题很重要。
②He didn’t know what to ask．(宾语) 他不知道该问些什么。
③ My question is when to start．(表语) 我的问题是何时开始。

②I can’t afford to buy such an expensive computer. 我买不起这么昂贵的电脑。
③He pretended not to know the facts. 他佯装不知实情⑵做宾语的不定式如果带有自己的补足语,则须用it做形式宾语,而将真正的宾语置于补足语之后,即:主语+动词+it+补语+to do句式。
如：Do you think it necessary to master a foreign language? 你认为掌握一门外语有必要吗？I find it interesting to stay with you. 我发觉与你呆在一起很有趣。
⑶动词+疑问词+不定式,这类动词常见的有：tell, advise, show, teach, find out, decide, discuss, learn, forget, inquire, know, explain, remember, see, understand, wonder等。
如：①Please show us how to do that. 请演示给我们如何去做。
②There are so many kinds of tape-recorders on sale that I can't make up my mind which to buy.有这么多的录音机，我都拿不定主意买哪一种。
㈣不定式作宾语补语☻不定式作宾语的补足语须从二个方面来掌握。

⑵常接不带to的不定式作宾语补足语的动词或短语有:一感(feel),二听(hear,listen to),三让(have,let,make),五看(look at,notice,observe,see,watch)但是这些句子变成被动语态时,需带上to ①主动：The boss made the workers work over ten hours a day in the past.→被动：The workers were made to work over ten hours a day by the boss.过去老板使工人们每天工作十多个小时。
②主动：I saw Li Lei fall down from his bike.→被动：Li Lei was seen to fall down from his bike.我看见李蕾从单车上摔了下来。
☻注意：help后的宾语补足语可以带to也可以不带to。
如：He often comes to help us (to) do some farming work. 他经常来帮我们干农活。
㈤不定式作定语动词不定式作定语需后置，与所修饰的词有主谓或动宾关系。

②This terrorist attack is a lesson to remember. 这次恐怖袭击事件是个应该记取的教训。
③I am afraid I cannot attend your party,for I have too many things to do.恐怕我不能参加你的晚会了,因为我有好多事情要做。
注意:☻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只能用动词不定式。
He was the last to realize the importance of this problem. 他没有及时意识到问题的重要性。
☻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。
①Who is the man to talk to? 要谈话的人是谁？②I need a pen to write with.我需要一支笔写字③He is a tough teacher to deal with.他是个很难对付的老师。
