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。
初中英语动词不定式部分知识讲解及练习
动词不定式一. 定义：动词不定式是非谓语动词的一种，它没有人称和数的变化，在句子中不能独立作谓语，但它仍保持动词的特点，既可以有自己的宾语和状语。
同时动词不定式又具有名词、形容词、副词的特征，在句中可以作主语、表语、宾语、宾语补足语、定语和状语。
二. 动词不定式的构成：to+动词原形三. 动词不定式作宾语动词不定式作宾语的注意事项（6点）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v_ing形式作宾语，意思差别不太大的动词有begin, start, like, love等。

八年级英语动词不定式+双宾语讲解及练习
专题三：动词不定式+双宾语一．动词不定式含义当我们要表示“想做某事、需要做某事或决定做某事”时，就会出现两个动词连用的情况，这时应如何表达呢?同学们自然会想到want to do sth.，need to do sth.和decide to do sth.等表达方式。
行为动词后的动词都采用了“to+动词原形”的结构。
我们把这种结构称为动词不定式。
动词不定式没有人称和数的变化，在句中不能作谓语。
二．动词不定式的功能1.动词不定式作宾语(1)动词+to do sth.表示的多为将来的行为。
如：want to do sth. / hope to do sth. / learn to do sth. / try to do sth. / decide to do sth. / forget to do sth. / remember to do sth. / stop to do sth./ plan to do sth.等(2)to有时可省略，结构为动词+do sth.had better do sth. / why not do sth.2.动词不定式作宾语补足语(1)宾语补足语是对宾语的补充说明，结构：“动词+宾语+动词不定式”。
其否定结构要在to do 前面加not,构成not to do。
如：allow sb. to do sth. / choose sb. to do sth. / want sb. to do sth. / tell sb. to do sth. / ask sb. to do sth. / invite sb. to do sth. /(2)在表示感觉、祈使等意义的动词help, make, let, have, feel, see等后接不带to 的不定式。
3.动词不定式作目的状语(1)如果表示“做某事是为了什么”，可以用动词不定式表示目的，常与soas，in order等构成短语不定式既可以放在句首，也可以放在句尾。
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.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。
动词不定式练习题及讲解
动词不定式用法要点讲解一、作主语动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种：(1)把不定式置于句首。
如：To get there by bike will take us half an hour.(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。
如：①It＋be＋名词＋to doIt's our duty to take good care of the old.②It takes sb+some time+to doHow long did it take you to finish the work?③It＋be＋形容词＋for sb＋to doIt is difficult for us to finish writing the composition a quarter of an hour.④It＋be＋形容词＋of sb＋to doIt is stupid of you to write down everything the teacher says.⑤It seems(appears)＋形容词＋to doIt seemed impossible to save money.二、作宾语⒈不定式作宾语①以下动词后，只能跟不定式作宾语。
如：agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,longmanage,offer,plan,prepare,pretend,promise,refuse,wish等，这些词大部分可接th at引导的从句。
如：When our visit to the farm was over, we expected to start back on foot.When our visit to the farm was over, we expected that we would start back on foot.②当复合宾语中的宾语是不定式时，先用形式宾语it代替不定式，把不定式置于补语之后，即：主语＋动词＋it＋补语＋to do句式。
初中英语动词不定式详细讲解+练习
动词不定式(to do)语法讲解动词不定式是由“to+动词原形”构成 (有时可以不带to)，其否定形式是“not to + 动词原形”。
它属于一种非谓语动词的形式,在句子中不能充当谓语,没有人称和数的变化,但它可以保留动词的性质,其本身可以带宾语或状语等附加成分（不定式和其附加成分称为不定式短语）。
动词不定式（短语）的句法功能非常广泛,在句中可作主语、宾语、补足语、表语、定语及状语等成分。
一、作主语（1）动词不定式作主语时,谓语动词常常用单数，例如：To do morning exercises is useful for our health. 做早操有利于我们的健康。
To sweep the floor is my duty every day. 每天打扫地板是我的责任。
把以上两句变为it作形式主语的句子：（2）如果动词不定式太长，常常用it 作形式主语,而将真正的主语——动词不定式后置，例如：To learn English well is important. 对我们来说,学好英语是重要的。
It’s important for us to learn English well．It took me half an hour to walk there．我走到那儿花了半小时的时间。
it不作形式主语：___________________________________________________________ 二、作宾语（1）能够接动词不定式作宾语的有ask, agree, beg, decide, determine，fail, hope, manage, offer, plan, prepare, pretend, promise, refuse, wish 及would like/love 等动词，但finish, enjoy, miss, appreciate, mind, advise, suggest 等动词后面通常只能接动名词（doing）作宾语，例如：I hope to visit this place again.我希望能再度访问此地。
中考英语专题讲练 动词不定式(含解析)
动词不定式动词不定式知识精讲非谓语动词指的是在句中不能单独作谓语，但保留动词的某些特征（如有自己的宾语或状语等）的动词形式。
非谓语包括动词不定式、现在分词、过去分词和动名词。
非谓语动词没有人称和数的变化，但要遵循基本的时态语态规则，在句中充当各种成分。
一、动词不定式基本构成注意：动词不定式在一些感官动词（see, watch, hear等）或使役动词（make, let, have 等）的后面，做宾补时，通常会省略to，如：The boss made me work ten hours a day.=I was made to work ten hours a day by the boss.这个老板让我一天工作十个小时。
二、动词不定式的语法功能动词不定式在句子中可充当主语、表语、宾语、宾补、定语和状语（即除谓语之外的各种成分）。
1. 不定式作主语1). 动词不定式短语作句子主语时，视为单数，谓语动词用第三人称单数，如：To make work more efficient is our goal.让工作更有效率是我们的目标。
2). 不定式短语作主语时，为了考虑句子的平衡，常用it作形式主语，而将真正的不定式主语放在句子后面，结构为：It+is/ was+adj. (+for sb.)+动词不定式，如上一句话也可写成：It’s our goal to make work efficient.我们的目标是让工作更有效率。
It’s very important for us to learn English well.学好英语对于我们来说很重要。
2. 动词不定式作宾语1). 动词不定式跟在及物动词后作宾语，这种形式非常常见，就是我们平时积累的一些动词后面跟to do形式，如：I have decided to study hard.我已经决定要刻苦学习。
常见的这类动词有：begin, choose, continue, decide, expect, fail, forget, hate, help, hope, learn, manage, mean, need, offer, plan, prefer, pretend, promise, refuse, try, want, wish, determine, afford, agree, start, like等。
