不定式省略to的九种情况总结

  总结是事后对某一阶段的学习或工作情况作加以回顾检查并分析评价的书面材料,它可以帮助我们总结以往思想,发扬成绩,让我们抽出时间写写总结吧。如何把总结做到重点突出呢?以下是小编整理的不定式省略to的九种情况总结,希望对大家有所帮助。

  不定式省略to的九种情况总结

  英语不定式中to有时可以省略,什么样的情况下可以省略,为你总结。小编为大家提供不定式省略to的九种情况总结,供大家参考。

  一、使役动词后省略to的情况

  在let, make, have等使役动词后用作宾语补足语的不定式必须省略to。如:

  My mother wouldn’t let me go to the film. 我妈妈不会让我去看电影的。

  I don’t like milk, but mother made me drink it. 我不喜欢牛奶,可是母亲强迫我喝。

  I would have him wait for me at the gate of the park. 我要他在公园门口等我。

  注意:

  1. 当使役动词用于被动语态时,要补上在主动语态中省略的to(主要是指make,let和have很少用于被动语态)。

  2. 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:

  He forced me to go with them. 他迫使我同他们一起去。

  The police obliged him to leave. 警方强迫他离开。

  二、感觉动词后省略to的情况

  在感觉动词后用作宾语补足语的不定式必须省略to。如:

  I watched her get into the car. 我看着她上了车。

  I saw the woman enter a bank. 我看见这个女人进了一家银行。

  We often hear her sing this song. 我们经常听到她唱这首歌。

  Did you notice her leave the house? 她离开屋子你注意到了吗?

  注意:

  1. 这里所说的感觉动词主要包括see, hear, observe, notice, feel, watch等。但是它们用于被动语态时,其后的不定式必须带to。如:

  The woman was seen to enter a bank. 有人看见这个女人进了一家银行。

  但是,用于以上句型的动词notice 和watch通常不用于被动语态。

  2. 类似地,动词look at和listen to后用作宾语补足语的不定式也不带to。如:

  We listened to the old man tell his story. 我们听这位老人讲述他的经历。

  3. 若动词feel后用作宾语补足语的不定式为 to be,则要带 to(其他情况不带 to)。如:

  They felt the plan to be unwise. 他们认为这个计划不明智。

  4. 若不定式为完成式,通常应带 to。如:

  I noticed her to have come early. 我注意到她来得很早。

  三、动词help后省略to的情况

  在动词help后用作宾语或宾语补足语的不定式可以不带to。如:

  Can I help (to) carry this heavy box? 我可以帮忙扛这个重箱子吗?

  Mother helped me (to) do my homework. 妈妈帮助我做作业。

  注意:

  1. 当 help 之后接一个较长的名词词组作宾语或当其中的不定式所表示的动作主语不直接参加时,不定式通常带to。如:

  Help the little boys at the back of the hall to carry the chairs out. 请帮大厅后面那些小男孩把椅子搬出去。

  These tablets will help you to sleep. 这些药片将对你的睡眠有帮助。

  2. 在当help用于被动语态时,不定式前的to不能省略。如:

  The boy was helped by a woman to collect his scattered coins. 那男孩由一个妇女帮他捡拾散乱一地的钱币。

  四、why (not)…后省略to的情况

  在why (not)…?之后的不定式不能带to。如:

  Why go with him? 为什么要同他一起去?

  Why not ask the teacher? 为什么不去问问老师?

  Why not try to expand your story into a novel? 你怎么不把你的故事扩展成小说呢?

  五、动词know后省略to的情况

  在“know+宾语+不定式”中,不定式有时省略to,有时不省,可分以下两种情况讨论:

  1. 若 know 为现在式,该结构中的不定式只限于 to be,且其中的to不能省略。如:

  I know him to be ill. 我知道他病了。

  We knew her to be honest. 我们知道她是诚实的。

  2. 若know为完成式或过去式,则该结构中的不定式可以用除 to be外的其他动词,且此时其中的to可以省留。如:

  I never knew him (to) do such a thing. 我从未听说他会干那种事。

  We’ve never known him (to) tell a lie. 我们从未听说他撒过谎。

  I’ve never known it (to) snow in July before. 我从未听说过有七月下雪的事。

  但在被动语态中不定式前的to不能省略。这样用的know不仅仅表示一般意义的“知道”,而是表示一种经历,因此常译为“曾……过”(用于肯定句时)或“(从来)没有……过”(用于否定句时)。

  六、介词except / but后省略to的情况

  用作介词except, but宾语的不定式有时带to,有时不带to。其大致原则是:若其前出现了动词 do,其后的不定式通常不带 to;若其前没有出现动词 do,则其后的不定式通常带 to。

  如:

  I had no choice but to wait. 除了等,我没有别的选择。

  He wanted nothing but to stay there. 他只想留在那儿。

  It had no effect except to make him angry. 除惹他生气外,没产生任何效果。

  She can do everything except cook. 除了做饭之外她什么都会。

  七、主语带do表语省略to的情况

  当主语部分有动词do的某种形式时,用作表语的不定式可以省略to。如:

  All you do now is (to) complete the form. 你现在要做的只是把这张表填好。

  The only thing to do now is (to) go on. 前进是现在唯一的出路。

  What I’ll do is (to) tell her the truth. 我要做的就是告诉她真相。

  八、并列不定式省略to的情况

  当两个或多个作用相同的不定式并列时,通常只需在第一个不定式前用to,其余不定式前的to可以省略。如:

  He told me to stay there and wait for him. 他叫我在那儿等他。

  I’m really puzzled what to think or say. 我真不知该怎么想怎么说。

  It is easier to persuade people than (to) force them. 说服人容易,强迫人难。

  但是,如果两者有对比关系,则后面不定式前的to不可省略。如:

  To try and fail is better than not to try at all. 尝试而失败总比不尝试好。

  九、省略不定式是否保留to

  在一定的上下文中,为了避免重复,有时不定式可以省略,但通常保留不定式符号to。如:

  I shall go if I want to. 如果我想去就去。

  “Don’t be late.” “I’ll try not to.” “不要来晚了。”“我尽量不来晚。”

  Don’t go till I tell you to. 等我叫你走你再走。

  注意:

  1. 若被省略的不定式为to be短语,则通常应保留to be。如:

  He is not the man he used to be. 他已不是原来的那个样子了。

  2. 有时省略不定式时,同时也可省略to。如:

  She may go if she likes (to). 她想去就可以去。 不定式省略to的九种情况总结,由提供。

  动词不定式作名词、形容词和副词,及其省略to的情况

  一、作名词

  名词在句子中可以作主语、表语、宾语、宾语补语、同位语,那么不定式也可以。

  1.主语

  a.主语在前:

  不带to:Saywell is good, butdowell is better. (Samuel Clarke)

  带to:To arragetime reasonably isto savetime. (F.Bacon) -更常见的是带to的情况

  b.主语在后:

  It is the most pleasant thing in the worldto strugglefor a noble idea. (Socrates)

  =To strugglefor a noble idea is the most pleasant thing in the world.

  2.表语

  I amto bea great man one day.

  He seemedto beashamed of himselft for getting so angry.

  It is betterto lighta candle than to curse the darkness. (Anna Eleanor Roosevelt)

  To speak knowledge isto spreadhappiness.

  3.宾语

  宾语概念的核心是,它是某个谓语的动作对象,它可以被补语修饰。

  a.动词宾语:

  I hopeto beable to come.

  Who daresto teachmust never cease to learn. (J.C.Dand, Motto)

  The driver failedto seethe other cars in time.

  Andersens father likedto readbetter than to make shoes.

  b.介词宾语:

  大多数介词不接不定式,但常见于这7个介词, about, besides, but, except, instead of, save, than

  He desires nothing butto studyabroad.

  I am aboutto startfor the States.

  注意2:为何此处介宾不称为表语?因为表语说明的是主语的静态状态,而不是包含宾语的动态动作

  4.补语

  补语概念的核心是,没它不行,没它句子意思就变了;不像定语和状语,完全可以省略。据此可以判断该不定式是补语,定语还是状语。补语要么修饰主语,要么修饰宾语。

  a.主语补语:

  We have been toldto waithere.

  注意3:也有人认为“主语补语”=“表语”,请君自便

  b.宾语补语:

  Adversity causes some mento break, othersto break records. (W.A.Ward)

  注意4:考点,如果动词是感官动词和使役动词causative verbs,用不带to的不定式,如see, feel, hear, find, get, behold, let, make...如下

  They were sorry to see himgo.

  We felt the houseshake.

  I heard himcough.

  We observed herwalkaway with a smile.

  She noticed the manlookat her.

  Love makes the worldgoround. (Charles Dickens)

  Let sleeping dogslie. (别去捅马蜂窝)

  5.同位语

  There is only one happiness in life,to love and to be loved. (George Sand)

  二、作形容词

  1.后置定语

  I have some questions about gravityto askyou.

  The grand essentials of happiness are: somethingto do, somethingto do, somethingto love, and somethingto hopefor. (Allan K. Chambers)

  Being polite is the gold keyto get alongwith others. (J.A.deAunznegui)

  Tom was the first manto comehere.

  The enemy failed in the attemptto landon the island.

  That was the last playto beperformed that year.

  2.前置定语

  严格意义上不是动词不定式,而是不定式构成的形容词

  Here theeay-to-usemodel.

  This is anever-to-be-forgottenday.

  3.表语

  All they could do isgobackto their own country.

  注意5:考点,主语含有实义动词do时to省略,如上

  The important thing in life isto havea great aim, and the determinationto attainit.

  三、副词

  1.目的状语

  She walked slowly on the ice in order notto falldown.

  We are hereto puta dent in the universe.

  2.结果状语

  They lift a stone onlyto dropit on their own feet.

  3.原因状语
