如题所述
是指英语里面的一种动词形态,它不是真正的谓语动词,但表达谓语动词的意思,所以用法上有将就。非谓语动词不定式(infinitive)I.基本形式:“to+动词原形”。有时to可省略。不能作谓语,没有人称和数的变化。既具有动词的特征----可以有自己的宾语和状语,又具有名词,形容词和副词的句法功能。不定式可以做主语,宾语,表语,定语,状语,同位语和宾语补足语式 态主动语态被动语态一般式to writeto be written完成式to have writtento have been written进行式to be writing完成进行式to have been writing不定式的否定式为:not+to doII.不定式的主动语态与被动语态:a. 一般式:表示谓语动词的动作与不定式的动作几乎同时发生,或发生在谓语动作之后。We must learn to speak EnglishI want to be a scientist when I grow up.b. 完成式: 表示不定式的动作早于谓语动词的动作发生。I'm sorry to have given you so much trouble.It's a good thing for him to have beencriticized.c.进行式:表示谓语动词的动作发生的时候,不定式的动作正在进行。He seems to be waiting for somebody.He pretended to be listening attentively.注:在某些结构中(尤其做宾语时, 不定式虽然表被动,但是用主动形式表示。 1.在的there be句式中,不定式的主动式可表被动的意思。There is no matter to drink here.2)当不定式与前面的名词构成动宾关系,又与另一代词或名词构成主谓关系,这时不定式的主动可以表被动。We have many difficulties to overcome.The next thing for them to do is to sweep the floor.He has no one to take care of. 1.当不定式做表语形容词的状语,又和句中的主语构成动宾关系,这时不定式的主动形式表被动意味。常可这样用的形容词一般1有以下几个:easy ,difficult , afraid, hard ,heavy,pleasant, nice, dangerous, important, interesting, bitter, light 等。They found the report was hard to understand.4) to let(出租),blame用主动代替被动形式表被动意味。The car is to let.III.句法功能: 1.做主语:当主语是个动宾结构时,或动状结构时,这时用不定式做主语。To learn English well is not easy.不定式短语做主语时,为了保持句子的平衡,往往以先行词做形式主语,而把不定式短语置于谓语动词之后。It's so nice to hear your voice.It cost us 5 0000 yuan to build the house. 1.作表语:a. 当表语是动宾结构或动状结构时,用不定式做表语。My job is to raise pigs. a.当主语是不定式时,表语也要用不定式。To see is to believe. a.主语是由动词转化或派生而来的名词,如果原动词要求接不定式,则表语也应当用不定式。 to buy a new car.My wish/hope/ idea/plan/purpose/intention is to visit Africa.to be a college student 1.作宾语:某些动词后,只能用不定式作宾语。如: allow ,afford, agree, apply, arrange, ask, choose, claim, decide, demand, desire, determine, expect, hope, wish, learn, manage, offer, pretend, promise, refuse, threaten等。We decided not to go with the work.Einstein once refused to speak on the radio for $ 1,000 a minute.有些动词既可接不定式作宾语,也可接动名词作宾语, 如:want, begin ,start, remember, need, forget, like, learn等,含义稍有不同。区别将在非谓语用法区别中讲解。注:a. 如果作宾语的不定式有自己的补语,则一般用先行词it做形式宾语,而将真正的宾语不定式后置。Do you think it better to translate in this way?They found it impossible to get there everything ready in time.2b. 不定式一般不做介词宾语,只有在极少数介词如:but, except ,besieds等后才行。此时不定式可带to或不带to。But前无动词do时,其后接带to的不定式:but前有动词do时,其后的不定式to常省略。In very cold winter weather a cold-blooded creature has no choice but to lie down and sleep.There was clearly nothing left to do but sit down on the little coach and weep.What do you like to do besides swim.但 “疑问词+不定式” 结构可以用做介词宾语.I have no idea about what to donext.The first was the question of what to call it 1.宾语补足语: 常带有不定式做宾语补足语的动词有(1). ask, force, expect, encourage,teach, cause, allow, beg, forbid, invite, permit, persuade, remind, want, warn, tell等.He told me to make a sentence with the word.(2). see, watch, notice, observe ; let, make, have ; listen to hear ;feel 这些动词后的不定式宾补,要省略 “to”. 但要变为被动语态时,要加上toShe had the pupils work out the problem.5). 定语: 放在它所修饰的名词或代词之后.不定式与它所修饰的名词或名词词组之间的关系为 A: 名词或名词词组是不定式的逻辑宾语; B: 名词或名词词组为不定式的逻辑主语. C:名词或名词词组与不定式既无动宾关系又无主谓关系A: He gave me something to eat.B: He needs someone to help him with his work..C: I have no time to do it.He has no money to buy the car.We must find a place to live.I have a better way to repair it.注: 带疑问词的不定式不直接做定语:(x ) That's the only way how to solve the problem.That's the only way to solve the problem.不定式做定语时可带逻辑主语,而且常用for引出.I have a letter for you to read.不定式一般作定语时,往往含有将来,必须等附加意味,相当一个定语从句.3 1.状语:目的状语:Yesterday I went to the station to meet my old brother.Mr. Smith came to China to studyChinese.常用的强调目的的短语in order to; so as to结果状语:He returned home tohear that his con has just join the army.He hurried to the school to find nobody there.常用的短语:so (such… as to +v.); too….to ; enough to +v.原因状语:(常表示喜怒哀乐等情绪)We were very excited to hear thenews.I'm glad to see you.表语形容词状语:结构为 be+adj. +to do sth.The article is easy to read.The man is hard to work with.We likely to attend the class.7)“疑问词+不定式”结构:主语: How to get rid of these things is a big question.宾语:I hardly knew how to write.表语:The question is where to find the answer. 1.定式的省略:A: 当两个或两个以上的不定式并列在一起时,第一个不定式带to,后面的不定式往往把to省去。Eg:I wished to finish my task and (to) get away.但是如果在对照的场合,则不可以省去:It is better to laugh thanto cry.B: 在感官动词see, hear, feel, watch, notice observe, listen to , look at 和使役动词let, make have的复合宾语中,不定式须省去to被动语态中要加上to.C: 在why引起的句子中省去to: Why not do it right now?Why quarrel with him?D: 在一些固定搭配后面,如:had better; would/had rather; but等,不用toE: help sb. (to) do sth.此句式中,可用to也可不用to.-ing form-ing form 既具有动词的一些特征(可带自己的宾语又可有自己的状语)又具有形容词,副词(现在分词)和名词(动名词)的句法功能。其形式为:v+-ing。现在分词表示动作正在进行和主动意味。一般式:dongI.(现在分词和动名词)主动语态:完成式:having done一般式:being

coming late made herteacher very angry.Do you mind my opening the window.在口语中,如果这种结构作宾语时,其中的物主代词常用人称代词的宾格来代替,用名词的普通格来代替名词所有格。如:Do you mind (me) opening the window?注:不过动名词的逻辑主语在遇有下列情况时,必须用名词的普通格(或人称代词的宾格)。 1.无生命词:The boy were alarmed by the door suddenly shutting.Fire burns better by oxygen being at work.(2) 有生命名词但表示 泛指意义。Have you ever heard of women

people4. 状语:时间状语When heated, ice will be changed into water.(=When it is heated,…)条件状语Given better instructions, the plants could have grown better.(=If they had been given…,)原因状语Given an apple, the child stoppedcrying.5. 宾补:She had his bike repaired yesterday.在英语中,有些动词即可接不定式作宾语,也可接-ing form(动名词)作宾语。有些意义区别不大,有些区别较大。如: 1.remember:remember +to do 记住要作某事remember + doing 记得过去曾经作过某事Please remember to

首先,一个句子里面,谓语只能有一个。
非谓语,是指动词,本来应该在句子中应作谓语,但在此之前已经有一个动词或系动词作谓语,该动词便以非谓语形式存在
例如
i run. run 是谓语
i am running. am这个系动词便作为谓语存在,run就必须变形为running,此为非谓语
或 i go to run. 前面有个go作谓语,run便不能作谓语,只能变形to run以非谓语形式存在本回答被提问者和网友采纳
