③ 英语的不定式是什么

不定式的定义是：在英语语法中，动词不定式是指动词中的一种不带词形变化从而不指示人称、数量、时态的一种形式。它之所以被称做不定式，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形式。

对于英语来说接不定式的单词多为“打算”“计划”“希望”“将要做某事”等表示未来（未做的事）的动词。同样与不定式表示不同,现在分词表示正在进行，一般性或经常性发生的行为。

（语态）动词和参与此动作的主语之间关系的一个术语。当主语是动作的发起者（或之一）时，称为主动语态，如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者，不定式一般要用被动语态形式。

3、进行式：表示动作正在进行，与谓语动词表示的动作同时发生。

4、完成进行式。

5、疑问词who，what，which，when，where，whether，how后可接不定式构成不定式短语，在句中作主语、宾语、表 语等。

⑤ 英语动词不定式

动词不定式：
动词不定式由“to+ 动词原形”构成，如： study, to play，动词不定式虽然不能作谓语动词用，但仍留着动词的特征，它可以带有所需要的宾语或状语而构成动词不定式短语，如：to study hard, to play table tennis。
1. 动词不定式的形式变化：动词不定式有下列时态和语态的形式变化。
语态式 一般式 完成式 进行式 完成进行式
主 动 to build to have built to be building to have been building
被 动 to be build to have been build

2. 动词不定式的基本用法：动词不定式能起名词、形容词和副词的作用，可在句中作主语、表语、宾语补足语、定语和状语用，如：
（1）作主语：To help each other is good.（动词不定式作主语时，一般可用it作形式主语，而将作主语的动词不定式置于句末，如：It is good to help each other.
（2）作表语：My job is to drive them to the power station every day. 动词不定式在系动词be之后作表语，与表示将来时的be + 动词不定式结构有所区别，如：Our plan is to set up another middle school for the peasants’ children.我们的计划是给农民子弟再成立一所中学。（句中的谓语动词为is，动词不定式to set up… 为表语，主语为plan，但plan并不是动词不定式的逻辑主语，即动词不定式 to set up所表示的动作不是主语plan产生的。）We are to set up another middle school for the peasants’ children.我们将为农民的子弟再成立一所中学。（句中的are to set up整个结构为句中谓语，主语为we，同时也是动词不定式to set up所表示的动作的逻辑主语，即动词不定式to set up所表示的动作是由we产生的）。
（3）作宾语：① 作及物动词的宾语，如：She wishes to be a musician.；② 作某些形容词的宾语：可以有动词不定式为宾语的形容词一般有glad, sorry, afraid, pleased, determined, willing, eager, anxious, ready, sure等，如：I am determined to give up smoking.；③ 动词不定式一般不作介词的宾语，但动词不定式之前如有疑问词时，就可作介词的宾语，如：Can you give us some advice on what to do next?
（4）作宾语补足语，如：Tell the children not to play on the street. 如果句中的谓语动词为see, hear, watch, notice, have, make, let等，作宾语补足语的动词不定式须将to省去，如：I saw a little girl run across the street.
（5）动词不定式在句中作宾语，如带有宾语补足语时，须先用it作形式宾语，而将该动词不定式后置，如：I don’t think it right to do it that way.
（6）作定语：动词不定式作定语时，须位于被其修饰的名词或代词之后，如：Is this the best way to help him? 和定语用的动词不定式如果是不及物动词，不定式后面就要用必要的介词，如：He is the man to depend on. 如果被不定式修饰的名词为place, time, way，不定式后面的介词，习惯上可以省去，如：The old man is looking for a quiet place to live.
（7）作状语：动词不定式可以作下列的状语：① 目的状语： Every morning he gets up very early to read English. 为了强调不定式表示目的的作用，可在不定式前加in order to或so as to（以便或为了），但应注意in order to位于句首或句中均可，而so as to不能位于句首，如：She reads China Daily every day in order to （so as to） improve her English. 将表示目的的不定式置于句首，也可强调目的的作用，如：To master a foreign language, one must work hard at it. ② 结果状语：They lived to see the liberation of their home town.他们活到亲眼见到了他们家乡的解放。③ too + 形容词或副词 + 动词不定式，表示“足能…”的结果，如：You are old enough to take care of yourself now.
3. 复合结构不定式：由for + 名词（或代词宾格）+ 动词不定式即构成复合结构的动词不定式。其中for本身无意义。for后面的名词或代词是不定式的逻辑主语，这种不定式在句中可作主语、表语、宾语、定语或状语，如：It is very important for us to get everything ready for the harvest. 当作表语用的形容词表示不定式的逻辑主语的性质或特征时，就用介词of而不用for引出不定式的逻辑主语，这些形容词一般有good, nice, kind, wise, silly, stupid, foolish, right, wrong, careless, impolite等，如：It is very kind of you to help him every day.
4. 疑问词 + 动词不定式：疑问代词和疑问副词后可加动词不定式构成不定式短语，在句中可作主语、表语或宾语，如：How to prevent them from swimming in this river is a problem.
5. 动词不定式的否定式：动词不定式的否定式是由not + 动词不定式构成，如：It’s wrong of you not to attend the meeting.
6. 动词不定式的时态形式所表示的时间关系：（1）一般式：动词不定式一般式所表示的动作是和谓语动词所表示的动作同时发生，但在多数情况下，是在谓语动词所表示的动作之后发生，如：We decided to plant more trees this spring.（其后），They often watch us play table tennis.（同时）；（2）完成式：动词不定式完成式所表示的动作发生在谓语动词所表示的动作之前，如：I am sorry to have kept you waiting.（3）进行式：动词不定式进行式所表示的动作正在进行中，而且与谓语动词所表示的动作同时发生，如：She happened to be writing a letter in the room when I came in.
7. 动词不定式的被动语态用法：如果动词不定式的逻辑主语为这个不定式所表示的动作的承受者时，不定式一般就用被动语态形式，如：What is to be done next hasn’t been decided yet.

⑥ 英语 动词不定式

选D首先因为sit 与chair有动宾关系。所以要加介词on然后因为forget是发生在seem前面的前面。表示过去的过去。是他过去的过去忘记带椅子了。。所以选D。。

⑦ 英语的动词不定式

一、不定式的基本形式: to＋动词原形,有时可以省略.

二、 动词不定式的特点: （1）没有人称和数的变化,在句子中不能作谓语.

（3）动词不定式具有名词、形容词和副词的特征,因此,在句中可以作主语、表语、宾语、宾语补足语、定语和状语.

三、动词不定式作宾语.即不定式直接跟在谓语动词后,是谓语动词涉及的直接对象.如果没有这个不定式,这个句子的意思就让人难以理解. 能直接带不定式作宾语的及物动词主要有: want, like , love , need , try , ask , learn , begin , start , forget , remember, hope , wish , agree, choose , fail , refuse , decide , afford , offer , make sure , take turns , would like , plan , hate , try one’s best 等.

【注意】如果动词不定式是不及物动词,后面就应有必要的介词. 如: He is looking for a room to live in. Give me a piece of paper to write on. He has nothing to worry about. There is not enough space to stand in on the earth.. She is a nice person to work with. a place to go to.

七、动词不定式作主语: 如 To learn a foreign language is not easy.

在现代英语中,常用it来作形式主语,而把真正的动词不定式主语放在后面.即句型:

“It is＋形容词＋for （ of） sb. to do sth.”中，当形容词是kind ，nice ， good ， clever ， careful ， careless , right , wrong , foolish 等表示人的性格特征时, 用of ; 如果形容词为difficult , easy , hard, important ,interesting, possible ,necessary 等表示事物的特征时, 用for. It is necessary / important / easy / hard/ possible for us to learn English well. It is very kind /nice / good of you to help me with my English.

※ 在句型: 主语＋find / think / feel / make +it +形容词+ to do sth.中,it为形式宾语.

I found it very important to learn English well. I think it easy to learn English well.

八、作表语: My job is to teach English. His wish is to become a scientist.

九、动词不定式和疑问词连用.动词不定式可以和疑问词what, which , how , when , where ,who 等连用,构成不定式短语,在句子中作主语、宾语、表语等成分.这时往往可以扩写成宾语从句; The question is how to use the computer.

（3）在助动词和一些情态动词如will , would , shall , should , can , could , may , might , must , do , does , did , didn’t , don’t , doesn’t 等的后面,用动词原形,即动词不定式不带to.

不定式有很多式，其中你先掌握一般式哦，如果这些都明白了 我再给你看看内其他的。这个是基容础哦·

不定式一般式就是指“to+动词原形”，其主要用法如下：
1. 表示未发生的动作，即表示发生在谓语动作之后的动作。如：
We decided to leave early. 我们决定早点动身。
He asked me to buy him some paper. 他叫我给他买些纸。

2. 表示同时发生的动作，即表示与谓语动作同时发生或略先于谓语动作的动作。如：
She is helping us to clean the window. 她在帮我们擦窗户。
I’m sorry to hear that. 听到这事我很难过。

3. 表示一般情况，即看不出动作的先后关系，而是表示一种情况或现象。如：
Washing the car seems to be your main hobby. 擦洗汽车似乎是你的主要爱好。
None of her many lovers seemed to want to marry her. 在她的许多情人节中似乎没有一个愿意娶她的。

⑨ 英语动词不定式是什么

在语法中，动词不定式是指动词的一种不带词形变化从而不指示人称、数量、时态的形版式。它之所以被权叫做不定式，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。
然而在一些语言里（例如葡萄牙语），存在着受时态、人称和数量影响的不定式形态。亦有些语言完全没有不定式，例如阿拉伯语、保加利亚语和现代希腊语。
在外语学习的课程中，动词不定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”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。
动词不定式可以作以上各种成分，但它毕竟是动词，所以有动词的属性。
动词不定式及其短语还可以有自己的宾语、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。这一使动者我们称之为逻辑主语。
