动词不定式中的省略动词不定式中的省略现象可分为两种情况,一是动词不定式符号to后的动词部分的省略;二是动词不定式符号to的省略.一,省略动词不定式符号to后的动词部分的情况1.一些表示心理活动,情感态度的动词或短语,如expect \want \hope \wish \love \hate \decide \plan \mean \try \would like \be ready \be afraid \be glad等后,动词不定式省略to后面的动词部分,但保留to.例如:(1)-I 'll be away on a business trip.Would you mind looking after my dog-Not at all .I'd be glad to. (2)-Will you go with me-Well ,I 'd like to.(3)-Will you go home tomorrow -No.I 'm going to a lecture,or at least I am planning to.2.不定式作宾语补足语时,省略to后的动词部分,即用to代替整个不定式.例如:(1)The boy wanted to ride his bicycle in the street but his mother told him not to.(2)You'd better finish the job on time if he ordered you to.3.在一些情态动词或助动词ought to \have to \used to \be able to 后.例如:(1)-Must I go now-No.You don 't have to.(2)-Are you planning to see your grandfather-No.But I ought to.二,省略动词不定式符号to的情况1.动词不定式作感官动词feel \see \notice \watch \find \hear\listen to \observe和使役动词have \make \let等的宾语补足语时,动词不定式符号to省略.如果这些动词用于被动语态,其后的动词不定式符号to不能省略(但let除外).例如: (1)We often hear him sing the song at home .(=He is often heard to sing the song at home.)(2)The y knew her verywell.They had seen her grow up from childhood.(=They knew her very well.She was seen to grow up from childhood.)注意:Mother got Tom to buy a pack of sugar.2.两个或两个以上的动词不定式由连词and \or \than \but连接时,从第二个不定式起,往往省略不定式符号to.但如果强调对比之意时不省略.例如:(1)She 'd like to take off her coat and have a break.(2)The students are taught to read,write and do many other things.(3)I t 's more difficult to do than to say .(强调语意前后对比)(4)The teacher came not to punish you but to help you.(强调语意前后对比)(5)I wondered whether to study or to work.(强调语意前后对比) 3.不定式作表语,用来解释主语或主语从句中do的精确含义时,往往可以省略动词不定式符号to.例如:(1)The first things he did was go up to her trainer and thank her for all her help during her training.(2)What we want to do now is lie down and rest.(3)What a dictionary does is help the students to find out the meaning and the usage of new words .4.在why或why not引起的表示建议或责问的省略问句中.例如: (1)Why get so excited(2)Why quarrel with your mother(3)Why not join us,Tom5.在一些类似情态动词词组had better \would rather \had best \rather than \can't but \can't help but等之后.例如:(1)In China it is important to invest in education rather than increase personal wages. (2)Jack would rather read than talk.(3)You'd better put on more clothes,or you'll catch a bad cold.(4)She dares to go to the lonely island by herself.I can 't but admire her bravery.6.在美国口语中,用在祈使语气中表示目的的动词come \go \try \run 之后的动词不定式符号to可省略,也可不省略.例如:(1)Come tell me if he arrives.(2)Go tell your mot her.(3)Run swim together.(4)Try open the door again.(5)Try to open the door again.(不省略语气更强烈)7.在一些固定短语中,make believe(假装)make do(凑合,设法对付)let slip(说出)leave go(放手)hear say(听说)let pass(忽略)let be(别打扰).例如:(1)The teacher didn 't let slip a word to us about the coming exam.(2)I 've heard say that Mary was about to come .(3)The boy made believe that he was reading when his father entered .(4)Let him be.(5)Don 't leave go(of)the fish. 另外值得注意的几种情况:1.need作行为动词时,后面接带to 的动词不定式;当dare作情态动词时,一般不用于肯定陈述句中;当dare作行为动词时,其后既可接带to的动词不定式,也可接不带to的动词不定式.例如:(1)I dare to swim across the river.(2)He dares to say that to his father.(3)She doesn 't dare(to)answer her teacher 's question.(4)We need to finish the job before lunch.2.关于动词help后接动词不定式的问题:一般说来,help后既可接带to 的动词不定式,也可接不带to的动词不定式(在美国英语及非正式文体中多见不带to).例如:(1)Would you like to helpme(to)carry the luggage (2)Help the baby(to)getup,Susan!3.but \besides \except作介词,后接动词不定式的情况:如果这些介词之前有行为动词do的各种形式,那么这些介词后的不定式不带to,反之则要带to.例如:(1)She could do nothing but cry .(2)What do you like to do besides swim(3)He has no choice but to leave.4.当like或want在由when\whenever \what \whatever \as \if等引导的状语从句中时,其后往往省略整个动词不定式.例如:(1)Come whenever you like .(2)Tom,don 't be nervous. Take whatever you want!(3)Do anything as you like.(4)You don 't have to come swimming if you don 't want.。

省略to的动词不定式用法归纳一、使役动词与to的省略当不定式用于let,make,have等使役动词后作宾语补足语,不定式必须省略to。
如:Letmehaveanothercupoftea给.我再来一杯茶。

Theymadehimtellthemeverything他.们强迫他把一切全告诉他们。
但是,当使役动词用于被动语态时,其后的不定式那么必须要带to。
如:他被迫一天工作20小时。
误:Hewasmadeworktwentyhoursaday.正:Hewasmadetoworktwentyhoursaday.注意,表示使役意义的let和have很少用于被动语态。
另外注意,force,oblige等虽然也表示“使〞,但它们后用作宾语补足语的不定式必须带to。
如:Theyforcedhertosignthepaper他.们强迫她在文件上签字。
Thelawobligedparentstosendtheirchildrentoschool法.律要求父母送子女上学。

不定式的省略一般有三种常见形式:省略动词原形而保留符号to 、省略不定式符号to和省略整个带to不定式。
一、省略动词原形而保留符号to动词原形的省略是指前面出现过的动词在下文再次出现时,可以单纯使用不定式符号to即:只省去动词,而保留符号“to ”。
如:. Don’t stop unless you have to (stop ).You may bring the dictionary with you if you want to (bring it ).---Will you go with me ?---Well, I’d like to ( go with you ).---Have you ever been to the seaside ?---No, we can’t afford to ( go to the seaside).就不定式在句中的所起不同作用这一角度来看,在语言意义十分清楚和语境非常明确的情况下,动词原形在以下几种情况下省略:1.动词不定式在care, want, hope, wish , expect, prefer, refuse, mean, try , promise, like , love(尤其在would like, would love, want等之后)等动词后作宾语时,常常可以省略动词原形。

例如:(1)Mr. Wang has his son write a diary every day.王先生让儿子每天写一篇日记。
(2)I knew him very much because I had seen him grow up from childhood.我很了解他,因为我是看着他长大的。

(2) She is noticed to water the garden every morning.人们看到她每天早上浇花园。
2.介词but或except之后跟不定式作宾语,且but或except前面有do的某种形式时,不定式符号to要省略。
例如:(1)There was nothing I could do but wait.我只能更待。
(2) She would do anything except clean the floor.除了扫地,她什么都愿意干。

如:Let me have another cup of tea.给我再来一杯茶。
She had him dig away the snow.她让他把雪挖走。
They made him tell them everyth ing.他们强迫他把一切全告诉他们。
但是,当使役动词用于被动语态时,其后的不定式则必须要带to。
如:他被迫一天工作20小时。
误:He was made work twentyhours a day.正:He was made to work twentyhours a day.注意,表示使役意义的let和ha ve很少用于被动语态。
另外注意,force, oblige等虽然也表示“使”,但它们后用作宾语补足语的不定式必须带t o。
如:They forcedher to sign the paper.他们强迫她在文件上签字。

英语动词不定式的省略的知识点
英语在我们的生活中是很重要的,今天小编就给大家分享一下英语的知识大全,大家有兴趣可以多多看看哦
英语知识
1、动词不定式的省略为了避免重复,我们常常把作宾语、宾补和谓语动词的一部分的不定式省略,只保留动词不定式的符号to。
现将常见省略不定式的几种情况通过实例加以简析,供大家参考:
(1)—How about coming to my house? —I’d love to if it doesn’t give you so much trouble. 在hope, like, love, promise, want, wish等词后作宾语的不定式常省略。
再如: You may go if you want to. She can get a job if she hopes to. —How about going hunting with me tomorrow? —I’d like to, but I have no time.
(2)Don’t close the window until I ask you to. 在allow, ask, tell 等词后作宾语补足语的不定式常省略。
再如:Don’t touch the light unless your mother allows you to. Don’t plant potatoes until the peasant tells you to.
(3)He didn’t want to hand in his composition, but he had to. 在be able to, be going to, have to, need to, enough to, used to等后的不定式需省略。
再如:I don’t sing much, now, but I used to a lot. If you don’t want to say anything at the meeting, you don’t need to.
She didn’t go out last night, because she was afraid to. 在afraid, glad, happy, pleased, sorry等词后作状语的不定式常省略。
再如:—Will you go with me to see the film tonight? —I’ll be glad to. 2、due to/be due to be due(to)有“应付给,应到的,预期的”之意,多用作表语,to不定式符号;而due to表示“由于,起因于”时,to是介词,相当于because of。
如: The train is due to arrive at 12.火车应于12点到。
When is the ship due?船预定何时到?。
