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。

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。

初中初中英语动词不定式的用法

初中初中英语动词不定式的用法篇一:初中动词不定式用法讲解初中动词不定式用法讲解动词不定式是动词的一种非谓语形式,又叫非谓语动词,它没有人称和数的变化,在句子中不能做谓语;它由“to+动词原形”构成,这里的to是动词不定式符号,本身没有词义,其否定形式常在to前加not;由于它仍保持动词的特点,可以有自己的宾语和状语,还可以带疑问词和由for引出其逻辑主语等形成动词不定式短语;不定式或不定式短语具有名词、形容词和副词的特征,在句子中可作主语、表语、宾语、宾语补足语、定语和状语等句子成分。

为使同学们更好地掌握其用法,现总结如下:一、动词不定式作主语动词不定式作主语时,为避免句子的头重脚轻,常用it作为形式主语,而真正的主语动词不定式后置。

如要说明动作的执行者,可在不定式前加for引导的短语;但如果表语是nice, kind, clever等描述动作执行者的性格、品质的形容词时,则应在不定式前加of引导的短语。

常用句型: 1,It +be+adj./n.+(for/of sb.) to do sth.(用of还是for决定于前面的adj, adj若是指sb.的特性,就用of,adj若是指sth的特性就用for)例句:It’s so nice of you to help me with my homework.你真是太好了,帮助我完成作业。

It’s very difficult for me to do the math homework.数学作业对于我来讲太难了。

2,It takes sb. some time to do sth.例句:It takes my mother all day to do the housework.做家务花了我妈妈一整天的时间。

二、动词不定式作宾语一些动词,如want, decide, hope, ask, offer, agree, choose, learn, plan, need, teach,prepare等,常接动词不定式作宾语(如want/decide to do sth.等)。

初中英语语法(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
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
后面能接不定式作宾语的动词有:agree, ask, choose, decide, forget, hope, learn, want, wish, would like等。

We hope to get there before dark. 我们希望天黑以前到那儿。

The girl decided to do it herself. 那个姑娘决定自己做那件事。

动词不定式作宾语的注意事项(2点)
1. 有些动词既可跟不定式作宾语,也可跟动名词作宾语,但含义不同:
remember to do 记住要做某事 remember doing 记得曾经做过某事
forget to do忘记要做某事 forget doing 忘记曾经做过某事
stop to do 停下来去做某事 stop doing 停止做某事
go on to do 继续做另一件事 go on doing 继续做原来在做的事
I remember seeing you somewhere before.
我记得以前在哪儿见过你。

Please remember to turn off the light when you leave.
离开时请记得关好灯。

2. 不定式作宾语时,如带有宾语补足语,则要把不定式放到后面,用it作形式宾语,构成“主语+动词+it+宾补(形容词、名词)+不定式”结构。

如:He found it very difficult to get to sleep. 他发现很难入睡。

四. 动词不定式作宾语补足语
1. 后面能接to不定式作宾语补足语的动词有:ask, order, teach, tell, want, wish, help 等。

The teacher told us to do Exercise 1. 老师要我们做练习一。

I want both of you to go. 我要你们俩去。

We helped her (to) repair her bike. 我们帮助她修理自行车。

2. 使役动词let, have, make及感官动词see, watch, notice, hear, feel等要以不带
to的不定式作宾补。

Let’s have a rest. 我们休息一会吧。

I saw him come in. 我看见他进来了。

感官动词后既可跟不带to的不定式作宾补,也可跟v-ing作宾补,前者表示动作的全部过程已结束;后者表示动作正在进行。

I saw him come downstairs.我看见他下了楼。

(说明他下楼了这件事)
