不带to的动词不定式通常有下面十八种情况

动词不定式何时不带to?在英语中，常见的不定式是带to的不定式，但在某些情况下，要使用不带to的不定式。

关于这类不带to的不定式，在使用时极易出错，因此，只有经常注意分析此类语言现象，才能达到正确理解的目的。

现将不带to的不定式的几种情况列举如下：一、在“动词＋宾语＋不定式”结构中，如果动词是表示感官意义的，如see，feel，hear，observe，notice，watch，listen to，look at等等，其后作宾语补足语的动词不定式结构不带to。

例如：Did you see him go into the house？你看到他进入那座房子了吗？She looked at（watched）other people play basketball．她在观看别人打篮球。

I didn't notice anyone enter the room．我没注意到有人进入那房间。

He listened to us talk．他听我们谈话。

二、在使役动词make，let，have等之后，作宾语补足语的不定式结构不带to。

例如：John made her tell him everything．约翰叫她把一切事情都告诉他。

The soldier had him stand with his back to hisfather．士兵要他背对他父亲站着。

Let me do it．让我来做。

注意：当这类动词转换为被动语态时，后面不带to的动词不定式要转换为带to的动词不定式（但have一般不用于被动句）。

但当句子的动词为let时，to仍可省略。

例如：The boy was seen to go into the house．有人看到那男孩走进那座房子。

They were made to work day and night．他们被迫日夜干活。

The prisoners were let go．罪犯被释放了。

省略to的动词不定式情况举例以下是小编为大家列举的省略to 的动词不定式情况，希望能帮助大家更好地认识不定式，提高英语水平。

1) 情态动词 ( 除ought 外，ought to)：2) 使役动词 let, have, make：3) 感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后作宾补，省略to。

8) 由and, or和than连接的两个不定式，第二个to 可以省去：9) 通常在discover, imagine, suppose, think, understand等词后，可以省去to be：He is supposed (to be) nice. 他应该是个好人。

举例：He wants to do nothing but go out.He wants to move to France and marry the girl.比较： He wants to do nothing but go out.He wants to believe anything but to take the medicine.典型例题1) ---- I usually go there by train.---- Why not ___ by boat for a change?A. to try goingB. trying to goC. to try and goD. try going答案：D. why not 后面接不带to 的不定式，因此选D。

不带to的不定式不带to的不定式1)在表示生理感觉的动词后的不定式不带to。

这类词有:feel 觉得 observe 注意到,看到 overhear听到watch注视 listen to听perceive察觉,感知notice注意 see看见 look at看 hear听On seeing the young child fell into the lake,Eric sprang to his feet,and went on the rescue.2)另一类是某些使役动词,如make, let,have等。

(注):①上述感觉动词与使役动词转换为被动结构时.其后的不定式一般需带to,如: He was seen to come.The boy was made to go to bed early.②在动词find与help之后,不定式可带to亦可不带to,如:He was surprised to find the sheep (to) break fence at this season.他发现羊在此季节越出栅栏,感到惊讶。

3)在do nothing/anything/everything but(except)结构中。

例如:Last night I did nothing but watch TV.昨天晚上,我除了看电视别的什么也没有干。

不带to的不定式用法之老阳三干创作动词不定式的基本形式是“to+动词原形”,它具有名词、形容词、副词的特征,因此在句子里用作主语、宾语、宾语补足语、主语补足语、定语、状语和表语.但在某些结构中,不定式又往往不带to,现将有关不定式不带to的用法年夜致综述如下：1．用在感觉动词see,watch,notice,look at,hear,listento,feel等后,作为宾语补足语,动词不定式不带to.如：We often heard them sing．我们经常听到他们唱歌.I saw her walk into the headmaster's office．我看见她走进了校长办公室.2．用在使役动词make,let,have等后,作为宾语补足语,动词不定式不带to.如：What makes you think I'm a farmer？你怎么认为我是一个农民？Now let me hear you play．现在让我听你演奏.I'll have my brother repair the radio for you．我要让我哥哥给你修理收音机.注意：感觉动词see,hear,watch,notice,feel,look at,listen to和使役动词let,make,have等用于主动语态时,动词不定式作为主语补足语则要带to.如：She was heard to sing in the next room．有人听到她在隔壁房间里唱歌.3．用在had better,had best（最好）, would rather（宁愿）, may/might as well (最好), cannot but (不能不, 肯定, 不能不), can not help but (不能不) , can not choose but (不能不,只好), 等结构后,词不定式不带to.如：I'd better go and look for him．我最好现在就去找他.You'd best get there before lunch．你最好午饭前达到那儿. We would rather wait till tomorrow．我们宁愿比及明天. 4．两个或两个以上句法功能相同的动词不定式并列使用时,通常只是第一个动词不定式带to,后面的动词不定式则不带to.如：So he decided to go and get some medicine for his cough．因此他决定去买点咳嗽药.They began to read and write．他们开始读和写.5．用在“Will you please+动词不定式”一类暗示邀请或命令的句型中,动词不定式不带to.如：Will you please bring me some chicken？请你给我带点鸡肉来好吗？Will you please ask her to call me tomorrow？请你让她明天给我打个德律风好吗？6．用在由“Why…”或“Why not…”一类暗示建议的句型中,动词不定式不带to.如：Why not join us？（＝Why won't you join us？）为什么不加入到我们傍边来呢？Why spend so much money？为什么花这么多钱呢？7．用在助动词will,shall,would,do和情态动词can,may,must,need,dare等后,动词不定式不带to.如：I can sing in English．我会用英语唱.I think it'll fit me quite well before long．我想这（件年夜衣）很快就会合身的.Unfair！How dare you say that？不公平！你怎么敢这么说？注意：ought to,have to中的to不能少.dare和need用作实义动词时,它后面的动词不定式要带to.如：The girl doesn't dare to swim in the river．这女孩不敢在河里游泳.8．用在动词help后作为宾语补足语,动词不定式既可以带to,也可以不带to.如：Will you help me repair my bike？请你帮我修理一下自行车好吗？Li Ping often helps me（to）do my lessons．李平经常帮手我做功课.9．用在do anything（nothing,everything）but或except一类结构后,动词不定式不带to.如：Can't you do anything but ask silly questions？难道你只会提些愚蠢的问题吗？There is nothing to do except wait until the rain stops．除静候雨停之外别无法子.9）在make do(make do with v.设法应付; make do without在没有...的情况下, 设法应付过去), make believe (假装, 假扮), let drop(使跌下, 丢下), let fall (放下(吊桥等) ,使(帷幕)落下) , let fly (v.发射, 猛烈, 攻击), let slip(v.放走, 松开, 错过, 无意中说出), let drive at (,v.瞄准打),let go of (释放, 放开), leave go of(v.松手)等固定搭配中,用不带to的动词不定式.例如：They let go of the rope.他们松开了绳子.John let fly a torrent of abuse at me.约翰朝我痛骂了一顿.10)当What one does/did ;The first thing one shoulddo 等含有实意动词do的结构在句中做主语,且表语是动词不定式时,to常省略.Eg.

不带to的动词不定式有哪些不定式是英语动词的非限定形式之一，是英语中一种非常活跃的语言现象，不带to的不定式（bare infinitive）是我们学习、掌握和运用这一语法现象的难点。

本文的目的就是要对不带to的不定式作一粗浅的探讨。

首先要指出的是，不带to的不定式的使用实际上非常普遍，主要用在情态动词和助动词will，shall，would，should，can，could，may，might，must…以及在作为情态动词的need和dare之后。

但因为这一点在学习英语的过程中极易掌握，故不在此赘述。

除此以外，在下列情况下也要使用不带to的动词不定式。

1．在see，feel，hear，watch，observe，listen to，look at, notice等感官动词或短语以及let，have，make等表示祈使意义的动词后面；不定式作宾语补足语不能带to；help后面的不定式可以不带to，也可以保留to；know在一定的条件下，后面的不定式作宾语补足语时可以不带to。

例如：I saw the man come out of the house．I heard her say that she was from Japan．We felt the house shake．They watched the sun sink into the sea．Did you notice him stop？They did not observe Jim come in and go upstairs．She was listening to him climb the stairs．Look at the boy run！I'll let you know as soon as I hear from her．I had him mend my watch．Electricity makes motors run．He helped me（to）plant trees．I have never known him sing so beautifully．不带to的动词不定式跟在上述动词后面时，情况比较复杂，有以下几个问题须特别注意：（1）当上述句子变成被动语态时，原来作宾语补足语的不定式则相应地成为主语补足语。

但是，在有些情况下动词不定式却不带to。

1. had betterhad better的意思是“最好……”，后接不带to的不定式，即接动词原形作宾语。

had在此不能看成是过去式，而应是一般现在时态。

如：You'd better come to school early tomorrow morning. 你最好明天早上早点来上学。

We'd better catch a bus. 我们最好乘公共汽车。

He had better go to see the doctor. 他最好去看医生。

2. Why not + 动词原形+ 其它?在“Why not + 动词原形+ 其它?”的句型中，Why not后接不带to的不定式，意为“为什么（怎么）不做……呢？”这种结构表示向对方征求意见或提出请求。

如：Why not come with me? 为什么不和我一起来呢？Why not ask the policeman? 怎么不问问警察呢？3. let, make, have使役动词let，make，have后接不带to的不定式作宾语补足语。

如：Let me see. 让我想想。

Let's go to the school by bus. 让我们乘公共汽车上学吧。

He made me have a try. 他让我试一试。

Who had you be so careless? 谁让你那么粗心呢？4. 表示感官的动词或短语如hear, see, watch, notice, look at, listen to等hear, see, notice等感观动词或短语等常接不带to的不定式作宾语补足语，表示动作已经做过或完成了。
