八年级英语动词不定式用法梳理(可编辑修改word版)

初二英语不定式用法梳理不定式用法口诀动词不定式基本结构：to+ do否定：not + to do作用：它具有名词、形容词和副词三大特点。

不做谓语。

1 不定式作宾语：决定（decide）同意（agree）计划（plan），主动提供（offer）希望（hope、wish），努力（try）想要愿意（wish, want, would like / love）。

★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. (p.98)2，不定式作宾语补足语：give、bring、lend，pass、show、send， leave、sell、tell， teach, 要用to另有buy、make，read和cook，要用for.3 特殊宾补：七个感官三使役，宾补要把to甩去；省“to”的不定式作宾语补足语：一感，二听，三让，四看，半帮助【诠释】一感：feel；二听：hear，listen to；三让：make，let，have；四看：see，notice，watch，observe 再加一个look at；半帮助：help。

4 主语it来帮忙，自己后面把身藏；不定式，作主语，行为多是指"具体"。

结构常用"主系表"，谓语用单则就好。

To learn English well is not easy.To say something is one thing，to do it is another．不定式，作主语，若太长，往后移；形式主语（it）去代替，免去头重无根底。

It's good for you to do some running in the morning．It's very nice of you to invite me．It cost me twenty yuan to buy the dictionary．5 疑问词后接上它，简化宾从人人夸（why后面的不定式不带to）；6 不定式做表语，跟在系动词后面。

八年级英语动词不定式用法梳理动词不定式是由“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;疑问词+不定式短语作主语可置于句首,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：1We decided to talk to some students about why they go there. 2He prefers to eat white bread and rice.3Id 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：1Could you please tell me where to park my car2It 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：4. 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：1When I left home, I forgot to bring it with me.2I 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.1I have so many clothes to wash today.2I can’t think of any good advice to give her.3We 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：1He 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：1There’s just so much to see and do here.2... but there are still many things to do the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：1Id 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：1This picture makes me feel excited2We 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.2Using 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：1In order to catch the early bus, she got up very early.2A group of young people got together to discuss this question.3She 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.2The 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.3Is 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;1I don’t know what to try next. 作宾语2Where 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;1What to do next=What will we / you do next2Why 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.随堂练习一动词填空;’m going to l isten to the radio.

主语系动词表语解析：haveawalk(散步)是动词短语，不能直接作主语；Tohaveawalk(散步)是动词不定式，可作主语（二）动词不定式作宾语1.如果宾语太长，可用it作形式宾语，构成“主语+谓语+it+宾语补足语(名词或形容词)+todosth”结构，谓语动词常为find、think、feel等。

Ithinkit'stooeasytosolvethisproblem.我认为解决这个问题太简单了。

Ifounditdifficulttostophim.我发现拦截他很困难。

Iwanttohaveawalk.（我）〈想要〉｛去散步｝。

初二不定式知识点归纳总结不定式是英语中的一种非谓语动词形式，由to + 动词原形构成。

在句中可以作主语、宾语、表语、定语、状语等成分，是英语语法中重要的一部分。

在初二阶段，学生需要掌握不定式的基本用法和常见结构。

本文将对初二学习不定式的知识点进行归纳总结。

一、不定式作主语不定式作主语时，常用句型为：It + be + 形容词 + 不定式。

例如：1. It is important to learn English well. 学好英语很重要。

2. It is necessary to finish the homework on time. 及时完成作业是必要的。

二、不定式作宾语不定式可以作为动词的宾语。

常见的动词有：hope, want, like, love, need, plan等。

例如：1. I want to go shopping with my friends. 我想和朋友们去购物。

2. She needs to study hard for the exam. 她需要为考试努力学习。

三、不定式作表语不定式作表语时，常用句型为：主语 + be + 不定式。

例如：1. His dream is to become a doctor. 他的梦想是成为一名医生。

2. The goal of our project is to promote environmental protection. 我们项目的目标是促进环境保护。

四、不定式作定语不定式可以修饰名词或代词，起到定语的作用。

例如：1. I have a lot of books to read. 我有很多书要读。

2. She is a girl to trust. 她是一个值得信任的女孩。

五、不定式作状语不定式可以作为动词的状语，表示目的、结果、原因等。

例如：1. She went to the library to borrow some books. 她去图书馆借书。

非谓语动词（综合讲解）在英语中，不是用作句子谓语，而是用于担任其他语法功能的动词，叫做非谓语动词。

非谓语动词没有人称和数的变化，不受主语人称和谓语动词时态变化的干扰，所以又叫非限定性动词。

非谓语动词有三种：不定式、动名词、分词。

其中分词又分为现在分词和过去分词。

一、动词不定式（一）不定式的形式不定式有两种形式：一是带 to 的不定式，一是不带 to 的不定式。

带 to 的不定式由不定式符号 to + 动词原形构成；不带 to 的不定式即为动词原形。

不定式的否定形式为 not (to) + 动词原形。

（二）不定式的用法1.作主语动词不定式短语作主语时谓语动词要用第三人称单数。

有时由于不定式短语作主语位于句首，使句子显得头重脚轻，故常用先行词 it 作形式主语，代替动词不定式，真正的主语动词不定式放在句末。

To speak a foreign language well is difficult.=It is difficult to speak a foreign language well.说好一门外语是困难的。

To remember enough words is necessary.=It is necessary to remember enough words.记住足量的单词是有必要的。

It is impossible to finish the work in two hours.=To finish the work in two hours is impossible.在两小时内完成这项工作是不可能的。

特别提示句子中有动词不定式作表语时，通常不用形式主语 it 的句型。

如：To see is to believe. 眼见为实。

不定式的逻辑主语可用“for + 逻辑主语”表示。

It's good for you to walk after supper. 晚饭后散步对你是有益的。

初二英语知识点归纳：动词不定式初二英语知识点归纳：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。

动词不定式用法归纳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。

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．（Lesson 10）．点击规律：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.以下动词只能to do 作宾语。

attempt企图 enable能够 neglect忽视 afford负担得起 demand要求 long渴望 arrange 安排 mean意欲，打算 begin开始 expect期望 appear似乎，显得 determine决定manage设法 cease停止 hate憎恨，厌恶 pretend假装 ask问 need需要 agree同意 desire愿望 love爱 swear宣誓 volunteer志愿 wish希望 bear承受 endeavor努力 offer提供 beg请求 fail不能 plan计划 bother扰乱；烦恼 forget忘记 prefer喜欢，宁愿 care关心，喜欢 happen碰巧 prepare准备 decide决定 learn学习 regret抱歉，遗憾choose选择 hesitate犹豫 profess表明 claim要求 hope希望 promise承诺，允许 start开始 undertake承接 want想要 intend想要 refuse拒绝 decide决定 learn学习 contrive设法，图谋 incline有…倾向 propose提议 seek找，寻觅 try试图b．love，like ，begin，start，hate ，prefer等词后面可以接不定式。

动词不定式用法不定式是动词的一种非限定式，它是不受主语的单复数、人称、时态、语态等的限定及影响的一种动词形式。

一、动词不定式的基本结构动词不定式的基本形式为：to+动词原形，有时可不带to。

不定式的否定形式是：not to+动词原形。

在句中除不能作谓语外，其他成分都可作。

如：主语、表语、宾语、宾语补足语、定语和状语等。

注意：不定式之前的to（又称为小品词）与介词to的功能不同。

介词to之后要接名词或代词的宾格，或相当于名词的短语作它的宾语；而不定式符号to的后面需要跟动词原形。

speak to him (to 是介词) 对他讲话to speak English (to 是不定式的小品词) 讲英语二、动词不定式的用法不定式在句中有各种作用，一般可归类为三种基本用法：作名词，作形容词，作副词。

(一) 不定式作名词的用法不定式起名词作用，在句子中担当主语、表语、宾语和宾语补足语。

⒈作主语名词用法的不定式和名词一样，可担任句子的主语。

To grow more trees here is very important.(=It is very important to grow more trees here.) 在这里多种些树是非常重要的。

To hear your voice is so nice.(=It is so nice to hear your voice.) 听到你的声音真高兴。

To speak English well is not easy for me.(=It is not easy for me to speak English.) 把英语说好对我来说并不容易。

To walk to school takes me twenty minutes.(=It takes me twenty minutes to walk to school.) 步行到学校我要花20分钟。

的句型中，it是形式主语，真正的主语是不定式；使用这种注意：在It is… to…”结构，可以避免句子的头重脚轻。
