英语动词不定式语法知识点归纳总结
动词不定式
考向一不定式的作用
1. 作主语：不定式作主语时，谓语用单数。往往用it 作形式主语，把不定式放在谓语后面。It took us two hours to finish the job.
2. 作宾语（1）动词+不定式。
?He managed to escape from the fire.
?I find it hard to get along with him. （it 作形式宾语）
（2）动词+疑问词+to，＂特殊疑问句+不定式＂相当于名词，作宾语。
?I don’t know what to do next/ how to do it next.
不定式短语作宾语时，如果还带有宾语补足语，往往把不定式短语放在宾语补足语之后，用it 作形式宾语。
?I find it necessary to learn a foreign language.
3. 作宾语补足语
（1）动词+宾语+不定式（to do ）。
?He warned me to be careful.
注意：可以用动词不定式作宾补的动词有：ask，tell，order，want，get，would like，like，advise，invite，allowhelp，wish，warn，expect，would prefer，encourage。
（2）表见解、看法的动词结构可为：动词+宾语+ to be 的不定式结构。
?We consider Tom to be one of the best students in our class.
The book is believed to be useful.（被动语态）
（3）There +不定式。
We didn’t expect there to be so many people there. 我们没料到会有那么多人在那里。
（4）在动词feel （一感），hear, listen to（二听），have, let, make（三让），notice, see, watch, observe, look at（五看）(即：吾看三室两厅一感觉)等后面的补足语中，不定式不带to，但变为被动语态后，必须带to。
?They saw the boy fall off the tree.
（5）help后面作宾语补足语的不定式可以带to，也可以不带to。
?I often help him (to) clean the room.
?I helped him (to) find his things.
4. 作定语
不定式作定语，修饰名词或代词，不定式和它所修饰的名词之间有逻辑上的主谓关系、动状关系、同位关系或动宾关系。不定式通常要放在这些被修饰的词后。
I have a lot of work to do.（动宾关系）
He is looking for a room to live in.（动状关系）
He is the first person to think of the idea.（主谓关系）
He has got a chance to go abroad.（同位关系）
5. 作状语
作状语，表示目的、结果、原因等，有时还有一些固定搭配的不定式短语，如in order to，so as to，so... as to，such...as to，enough to，too...to等。
（1）作目的状语，just to，only to（仅仅为了），in order to，so as to，so(such)... as to...（如此……以便……）
?He ran so fast as to catch the first bus. 他飞快地跑以便赶上第一班车。
（2）作结果状语，表事先没有预料到的，要放在句子后面。
?He hurried to the post office only to find it was closed.
（3）作原因状语。
?We were very excited to hear the news.
（4）作条件状语。
?To turn to the left, you could find a post office.
6. 作表语
不定式可放在be动词后面，构成表语。
?The question is how to put it into practice.
考向二不定式的时态和语态
1. 不定式的时态
（1）现在时：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.
（2）完成时：表示的动作发生在谓语动词表示的动作之前。
?I’m sorry to have given you so much trouble.
?He seems to have caught a cold.
（3）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.
（4）完成进行时：表示动作从过去某个时间开始，一直延续到现在，并有可能持续下去。?She is known to have been working on the problem for many years.
2. 不定式的语态
当不定式的逻辑主语是其动作的承受者时，就用被动式。
He was seen to enter the hall.
考向三省to 的动词不定式
一、使役动词后省略to的情况
在let, make, have等使役动词后用作宾语补足语的不定式必须省略to。如：
?My mother wouldn’t let me go to the film. 我妈妈不会让我去看电影的。
?I don’t like milk, but mother made me drink it. 我不喜欢牛奶，可是母亲强迫我喝。
二、感官动词后省略to 的情况
在感觉动词后用作宾语补足语的不定式必须省略to。如：
?I watched her get into the car. 我看着她上了车。
?I saw the woman enter a bank. 我看见这个女人进了一家银行。?We often hear her sing this song. 我们经常听到她唱这首歌。?Did you notice her leave the house? 她离开屋子你注意到了吗?
三、动词help后省略to的情况
在动词help后用作宾语或宾语补足语的不定式可以不带to。如：
?Can I help (to) carry this heavy box? 我可以帮忙扛这个重箱子吗？
?Mother helped me (to) do my homework. 妈妈帮助我做作业。
注意：
1. 当help 之后接一个较长的名词词组作宾语或当其中的不定式所表示的动作主语不直接参加时，不定式通常带to。如：
?Help the little boys at the back of the hall to carry the chairs out. 请帮大厅后面那些小男孩把椅子搬出去。
?These tablets will help you to sleep. 这些药片将对你的睡眠有帮助。2. 在当help用于被动语态时，不定式前的to不能省略。如：
?The boy was helped by a woman to collect his scattered coins. 那男孩由一个妇女帮他捡拾散乱一地的钱币。
四、why (not) …后省略to的情况
在why (not)… ?之后的不定式不能带to。如：
?Why go with him? 为什么要同他一起去？
?Why not ask the teacher? 为什么不去问问老师？
?Why not try to expand your story into a novel? 你怎么不把你的故事扩展成小说呢?
五、介词except / but 后省略to的情况
用作介词except, but宾语的不定式有时带to，有时不带to。其大致原则是：若其前出现了动词do，其后的不定式通常不带to；若其前没有出现动词do，则其后的不定式通常带to。如：
?I had no choice but to wait. 除了等，我没有别的选择。
?He wanted nothing but to stay there. 他只想留在那儿。
?It had no effect except to make him angry. It had no effect except to make him angry.
除惹他生气外，没产生任何效果。
?She can do everything except cook. 除了做饭之外她什么都会。
六、主语带do表语省略to的情况
当主语部分有动词do的某种形式时，用作表语的不定式可以省略to。如：
?All you do now is (to) complete the form. 你现在要做的只是把这张表填好。
?The only thing to do now is (to) go on. 前进是现在唯一的出路。
?What I’ll do is 我要做的就是告诉她真相。
七、并列不定式省略to 的情况
当两个或多个作用相同的不定式并列时，通常只需在第一个不定式前用to，其余不定式前的to可以省略。如：?He told me to stay there and wait for him. 他叫我在那儿等他。
?I’m really puzzled what to think or say. 我真不知该怎么想怎么说。
?It is easier to persuade people than (to) force them. 说服人容易，强迫人难。
但是，如果两者有对比关系，则后面不定式前的to不可省略。如：
?To try and fail is better than not to try at all. 尝试而失败总比不尝试好。
八、省略不定式是否保留to
在一定的上下文中，为了避免重复，有时不定式可以省略，但通常保留不定式符号to。如：
?I shall go if I want to. 如果我想去就去。
?＂Don ’t be late. ＂＂I’ll try not to. ＂＂不要来晚了。＂＂我尽量不来晚。＂
?Don’t go till I tell you to. 等我叫你走你再走。
注意：
1. 若被省略的不定式为to be短语，则通常应保留to be。如：
?He is not the man he used to be. 他已不是原来的那个样子了。
2. 有时省略不定式时，同时也可省略to。如：
?She may go if she likes (to). 她想去就可以去。
高中英语不定式语法注意事项
作为三大非谓语动词之一的动词不定式，语法功能非常强大，除了谓语之外的句子成分都能够充当。如：
主语：To help others will make you popular. 乐于助人会使你受到大家的欢迎。
宾语：I really like to watch football matches. 我非常喜欢看足球比赛。
定语：I have a lot of housework to do today. 我今天有很多家务要做。
状语：She has to get up early every day to catch the first bus. 她为了赶上第一班公交车不得不每天都早起。
宾补：The teacher advised us to practise a lot. 老师建议我们多加练习。
表语：His job is to design new machines. 他的工作是设计新机器。
独立成分：To be honest, he is really a good man. 说实话，他真的是个好人。
不过，在使用不定式时我们应注意以下问题：
1. 不定式的否定形式
不定式的否定形式为not to do sth，它同动词的-ing形式，动词的-ed形式一样，不能单独作谓语。它没有人称和数的变化，但可以带自己的宾语、状语以及逻辑主语。如：
Father told me not to stay alone outdoors at night. 父亲告诉我晚上不要一个人在外面。
To learn a foreign language well is very important for us. 学好一门外语对我们来说是很重要的。
( a foreign language作不定式to learn的宾语，well 用作不定式的状语，us 为不定式的逻辑主语)
2. 不定式与逻辑主语
(1) 当用作表语的形容词表示不定式逻辑主语的性质或特征时，逻辑主语由of引出。如：
It’s very kind of you to help us. 你能帮助我们真是太好了。
此时，不定式的逻辑主语和形容词可以构成系表结构，若不能，逻辑主语须由for引出。即本句可改写成：You are very kind. 而1 中例句不可改成:We are very important.
(2) right, wrong既可用于for sb to do sth，也可用于of sb to do sth。如：
It’s right/wrong for/of the king to punish the orphan. 国王惩罚那个孤儿是正确的/错误的。
(3) 不定式作主语时往往用形式主语it代替置于句首，不定式则置于句尾作真正主语。如：
It is very necessary to learn a foreign language. 学习一门外语是很有必要的。
(4）不定式也可作真正宾语，形式宾语也用it充当。如：
I think it very hard to learn maths. 我认为学习数学很困难。
.3. 不定式作定语时需注意的问题
(2) 如果不定式是不及物动词，作定语时需根据需要加适当的介词。如：
He is only a child to look after. 他只是一个需要照料的孩子。
(3) 当被修饰的词是way，place，time时，常省略介词。如：
They are looking for a place to live（in）. 他们正在找住的地方。
4. 不定式作状语时需注意的问题
(1) 不定式作状语时可以表示目的、原因、结果和比较等，在表原因和结果时不可位于句首。如：
I’m very glad to see you.见到你很高兴。
They lived to see the liberation of their hometown. 他们一直活到见到家乡解放。
(2) 作结果状语时，有时可在不定式前加上only，表示出乎预料的结果。如：
She hurried upstairs, only to find her uncle lying on the ground, dead. 她快步赶到楼上，却发现她的叔叔躺在地上，死了。
5. 不定式作宾补时需注意的问题
不定式位于感官动词和使役动词后作宾补时需省略不定式符号to, 但当这些词用于被动语态时需恢复to。这类词我们可以通过一句口诀来记住：“一听二看三感四使”。一听是指hear，listen to ；二看是指notice，see ，watch 、observe；三感觉是指feel，四使是指make、let、have ；这些动词后面可跟随省略to 的不定式作宾补。但let在主动被动中都不带to。
6. “疑问词+不定式”相当于一个名词，在句中可作主语、宾语、表语等。如：
How to finish the work on time is a problem. 怎样按时完成这项工作是一个问题。（主语）
We don’t know where to go. 我们不知道该去哪里。（宾语）
7. 不定式的省略
（1）当不定式所表示内容在上文已经出现，为避免重复，总是把不定式里的动词及其后续部分省略，只保留to。如：
She wants to come but her parents won’t allow her to. 她想来但她的父母不允许她来。
（2）当被省略的不定式的内容是作助动词用的have 或be 的任何形式时，to 后要保留到原形have 或be。如：
He didn't come, but he ought to have. 他没有来，但他应该来的。
Jane is not what she used to be. 珍不再是她从前的样子了。
（3）不定式在but，other than后面时，如果介词前有行为动词do的某种形式，介词后的不定式不带to，否则就要带to。另外，在can’t choose but, can’t help but, can’t but结构后面的不定式也要省略to。如：
We could do nothing but/other than wait. 除了等我们什么也不能做。
We have no choice but to wait. 我们除了等别无选择。
让大脑放松的小窍门
伸个懒腰、闭眼眯一会儿、深呼吸几次……这些短暂的休息，能让高速运转的大脑得到充分休息。
抽10分钟就够了
如果学校没有午休时间，那就抽出10分钟午睡。这样做就能使人保持至少2小时以上精神活跃。如何用10分钟时间，打造一个完美的小憩?
选对时间。这10分钟最好在饭后，而且在11:00—13:00之间。
睡前设闹钟。许多人因担心睡过头，结果很难入睡，而设好闹钟会使人消除这一担忧。
听着“白噪音”。为了完美的午睡，应该找一个黑暗、安静的场所。如果必要的话，可以使用眼罩、耳塞，或者下载一些海浪声、风声等“白噪声”来排除干扰。
认真伸一个懒腰
伸懒腰能增加对心、肺的挤压，促进心脏泵血，增加全身的供氧，还有利于全身肌肉的收缩和呼吸加深。大脑血流充足了，人自然感到清醒、舒适。
伸懒腰时保持身体放松，将双手五指交叉，掌心向上置于头顶，脚尖交替伸直和上钩，四肢伸展的同时，还可以向左右转体，大约持续30秒钟。
发呆5分钟
专家研究显示，发呆是最简单的减压方式。
研究者发现，心无杂念、脑子里什么也不想的时候，大脑中的α脑电波得到加强。这种特殊的脑电波可以抑制信息超载，让注意力和意念更加集中，从而改善情绪，减轻压力，缓解焦虑不安，还能加强记忆力，缓解疼痛，并提高免疫力。
另有研究发现，每天适当发会呆能将焦虑和抑郁风险降低25%。
做个头部按摩
简单的头部按摩自己就能做，比如梳头疗法。选择个人比较能接受的力度，用十指指肚或指尖，从双眼眼眶上沿开始顺着往后梳头，梳至颈后风池穴，反复数次，也可以用牛角或实木梳子代替手指。
这个动作可以刺激头皮的神经末梢和经穴，有效松弛头部神经的紧张状态，促进局部血液循环，尤其是从事脑力劳动的人，每天坚持梳头3～5分钟，对于解除疲劳和大脑皮层的紧张状态大有好处。
吃点健康零食
在两餐之间或餐前吃点健康零食，既可以让你得到身心的放松，还有助于补充营养。
不妨在教室储备些零食，在上午10点或下午3点左右给自己来个短暂的“茶歇”，酸奶、水果、坚果等都是比较健康的零食选择。
出门晒晒太阳
晒太阳的好处不胜枚举，但国人晒太阳的时间仍远远不够。不妨在你感到疲倦时，把晒太阳这个功课补上。
上午10点和下午4点是晒太阳的最佳时间，此时可以散散步。可以多晒晒背部、双腿和头顶，有助于钙的吸收、合成，还能提高免疫力，每次晒15～20分钟为宜。
和别人分享一件趣事
欢笑是最好的减压良药。学习一两个小时后，和同学或家人分享一件趣事，或看看漫画书、搞笑视频等，都可以瞬间降低体内的压力激素。也可以走动一下，与同学聊聊天，身体也能得到放松。

初中英语动词不定式十大考点解析(整理)
初中英语动词不定式十大考点解析 动词不定式是动词的一种非谓语形式，没有人称和数的变化，不能单独作句子的谓语。其构成形式为"to+动词原形"，to为动词不定式的符号，本身无意义。 一、动词不定式作主语 动词不定式作主语时，可以直接放在谓语动词前面的主语位置，也可以用先行词it作形式主语，而将真正的主语(不定式)置于后面。常见的句式有：(1)It is +形容词(of sb)to do sth. (2)It is +名词(for sb)to do sth. (3)It takes sb some time to do sth. (4)It is +形容词(for sb)to do sth. 句式(1)中常用nice，kind，clever，good，right，wrong，foolish，careless等形容词，与介词of 搭配，这些形容词常表述不定式逻辑主语的属性或性质; 句式(4)中常用hard，difficult，easy，important等形容词，与介词for搭配，表示不定式表示的动作、行为的性质。 1.

English语法之不定式及名词后加动词不定式 在English语法中，动词不定式是动词的一种不带词形变化从而不指示人称、数量、时态的形式。基本形式是to+动词原形，部分词和词组不带to也表达不定式。之所以叫做不定式，是因为动词不被限定、或者说不被词形变化所局限。不定式属于非谓语动词，即不能单独作谓语。但它毕竟是动词，所以有动词的属性，也可以理解此类动词形式为不定式状态的动词。动词不定式及其短语有自己的宾语、状语，虽然动词不定式在语法上没有表面上的直接主语，但它表达的意义是动作，这一动作一定由使动者发出,这一使动者称之为逻辑主语。 动词不定式可以作多种句子成分。 在外语学习的课程中，"动不式"的一般现在时被称作“词典用词”，因为它一般被用作词典中该动词的词头。 对于英语来说接不定式的单词多为“打算”“计划”“希望”“将要”等表示未来的动词。同样与不定时表示不同的动词不定式表示正在进行，一般性或经常发生性的行为。 A.不带to的不定式有四种情况： 1、1、let, make, have等使役动词后。 例如： Let us go!出发 The boss made the child labors work the whole night.老板逼迫童工整夜 劳作 注意：这些情况在被动语态中，不可省to. 例如：The child labors were made to work the whole night. 2、would rather, had better后。
例如：You had better stay at home.你最好呆在家 3、w hy…/w hy not…后。 例如：Why not have a happy rest on Sunday? 不定式的否定式是not to do.. / never to do..，不带to的不定式的否定式是not do.../ never do.. 例如：His parents tell him never to drive after drinking.他的父母告诉他酒后严禁驾驶 4.感官动词see, watch, look at, hear, listen to, smell, feel, find，notice等后作宾语补足语。 例如: I saw her dance.我看到她在舞 除以上四种情况之外，都不得省略to B. 动词不定式的复合结构 动词不定式的复合结构是“for sb. to do sth. / 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，不说明人的特性。 例如：

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 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
