不定式省略to的几种情况及练习题

不定式省略to的几种情况及练习题

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：

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 everything.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 twenty hours a day.

正：He was made to work twenty hours a day.

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：

They forced her to sign the paper.他们强迫她在文件上签字。

The law obliged parents to send their children to school.法律要求父母送子女上学。

二、感觉动词与to的省略

当不定式用于表示感觉的动词feel, hear, notice, observe, see, watch, look at, listen to等作宾语补足语时，不定式必须省略to。如：

We all felt the house shake.我们都感觉这房子在震动。

I heard him go down the stairs.我听见他下楼了。

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

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

但是，当feel后用作宾语补足语的不定式为to be时，则不能省略to。如：

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

注意，当这些动词变为被动语态时，不定式前的to不能省略。如：

They were heard to break a glass in the next door.听见他们在隔壁打破了一个玻璃杯子。

另外，若用作宾语补足语的不定式为完成式，则通常应带to。如：

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

三、介词except / but与to的省略

当不定式用作介词except或except的宾语时，该不定式有时带to，有时不带to，情形比较复杂，大致原则是：其前有do，不定式不带to；其前没有do，不定式通常带to。如：

He likes nothing except to watch TV.除了看电视外，他什么都不喜欢。

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

There’s little we can do except wait.除了等待我们没有什么办法。

I could do nothing except agree.我除了同意，没有别的办法。

四、help与to的省略

当动词help后跟一个不定式用作宾语或宾语补足语时，不定式可以不带to，也可以不带to。如：Can you help (to) carry this table upstairs?你能帮忙把桌子搬到楼上去吗?

I have lost my watch. Will you help me (to) look for it?我把表丢了，你能不能帮我找一下?

但是，当help用于被动语态时，其后不定式必须带to。如：

Millie was helped to overcome her fear of flying.米利被帮助克服了她的飞行恐惧。

另外，当不定式为否定式时，其中的to通常不宜省略。如：

How can I help my children not to worry about their exams?我怎样才能帮助我的孩子们不为他们的考试着急呢?

五、固定搭配与to的省略

1、Why not...? = Why don't you...? 习惯上接动词原形，不能接带to不定式或现在分词，主要用于表示同意、赞成、劝诱等，其意为“为什么不……呢”。如：

Why not go with him? = Why don't you go with him? 为什么不和他一起去呢？

2、had better...，最好做某事，如：

You had better stay here. 你最好呆在这里。

3、“would rather+动词原形”意为“宁愿做某事”。如：

We’d rather stay at home.我们宁愿呆在家里。

I would rather not tell him.我宁愿不告诉他。

4、prefer+不定式+rather than+动词原形，其意为“宁愿做某事而不愿做另一事”。如：

I prefer to walk there rather than go by bus.我宁愿走着去，而不愿坐公共汽车去。

He prefers to read rather than watch television.他喜欢读书而不喜欢看电视。

但，prefer+动名词+to+动名词，其意为“宁愿做某事而不愿做另一事”。如：

He prefers swimming to riding as a sport.作为一项运动项目，他更喜欢游泳而不是骑马。

注：这类结构的prefer前有时也可用would, should等。如：

We would prefer playing outdoors to watching television.我们宁愿在外面玩而不愿看电视。

习惯上只接动名词（V+ING）作宾语的动词

常用动词有：admit承认、advise建议、allow允许、appreciate感激、avoid避免、consider考虑delay 推迟、deny否认、discuss讨论、dislike不喜欢、enjoy喜爱、escape逃脱、excuse原谅、fancy设想、finish完成、forbid禁止、forgive原谅、give up放弃、imagine想像、keep保持、mention 提及、mind介意、miss没赶上、pardon原谅、permit允许、practise练习、prevent阻止、prohibit禁止、put off推迟、report报告、risk冒险、stop停止、suggest建议、understand理解等，这些动词后面常接动名词作宾语。

另在一些固定搭配中也常接动名词作宾语。如：

1、insist on doing坚持要做某事。如：

He insisted on doing it by himself. 他坚持要一个人做。

2、have difficulty /trouble (in) doing sth. 相当，意为“在做某事方面有困难、麻烦”。如：

She has difficulty/trouble (in) learning maths well. 她学好数学有困难。

3、be busy (in) doing sth. 忙于做某事。如：

They are busy (in) doing with the trouble. 他们正在忙于处理那个问题。

【典型用法实例】

I advise waiting a few more days.我建议再等几天。

They avoided mentioning that name.他们避免提到那个名字。

He denied having been there.他否认到过那里。

He disliked being laughed at.他不喜欢别人笑他。

I’ve enjoyed seei ng you and talking about old times.我见到你一起谈往事非常高兴。

We don’t allow (permit) smoking on this plane.在这架飞机上我们不允许抽烟。

I admit breaking the window.我承认窗子是我打破的。

Try to imagine being on the moon.设法想像你是在月球上。

He made a New Year’s resolution to give up smoking.他下了新年决心要戒烟。

They risked losing everything.他们冒失去一切的危险。

He tried to escape being punished.他设法逃避惩罚。

You shouldn’t keep thinking about it.你不应老想着这事。

Would you mind going with her?你可否同她一起去?

I can’t understand neglecting children like that.对孩子那样毫不经心，我不能理解。

We only missed seeing each other by five minutes.我们只因差五分钟而未能见面。

I suggest doing it in a different way.我建议以另一种方法做这事。

I put off writing from day to day.我日复一日地推迟写它。

【几点用法说明】

(1) 有的动词后接动名词作宾语时通常带有逻辑主语：

The rain prevented his coming.下雨使他不能来。

Excuse my opening your letter by mistake.原谅我不慎把你的信拆开。

(2) 有的动词(如advise, allow, forbid, permit等)后虽然不能直接跟不定式作宾语，但可接不定式作宾语补足语：

He advised buying a computer.他建议买台电脑。

He advised her to buy a computer.他建议她买台电脑。

(3) 有些动词(如consider, understand, discuss等)虽不接不定式作宾语，却可接“疑问词+不定式”作宾语：Have you considered how to get there?你是否考虑过如何到那儿去?

She doesn’t understand how to look after him.她不知道应如何照顾他。

We discussed what to do and where we should go.我们讨论了该怎么办及到哪里去。

习惯上接不定式作宾语的动词

通常只接不定式(而不是动名词)作宾语的动词有：afford负担得起、agree同意、arrange安排、ask要求、care想要、choose决定、decide决定、demand要求、determine决心、expect期待、fail未能、help帮助、hesitate犹豫、hope希望、long渴望、manage设法、offer主动提出、plan计划、prepare准备、pretend假装、promise答应、refuse拒绝、want想要、wish希望等。如：

I can’t afford to buy a car.我买不起汽车。

She refused to help me.她不肯帮助我。

He agreed to come over right away.他同意马上就来。

He managed to avoid an accident.他设法避免了一次事故。

The boy decided not to become a sailor.那孩子决定将来不当水手。

He chose not to go abroad until later.他决定晚点出国。

He pretended not to know the facts.他佯装不知实情。

v+sb to do sth用法

通常可带不定式作宾语补足语的动词有advise建议, allow允许, ask要求、叫, bear忍受, beg请求, cause 引起, command命令, encourage鼓励, expect期待, forbid原谅, force强迫, get使, hate讨厌, help帮助, intend打算, invite邀请, leave离开, need需要, oblige逼迫、责成, order命令, permit准许、允许, persuade 说服, prefer宁愿, request要求, remind提醒, teach教, tell告诉, trouble麻烦, want想要, warn警告, wish 希望、hope希望等：

The doctor warned him not to smoke.医生告诫他不要抽烟。

My parents encouraged me to study abroad.父母鼓励我出国留学。

I tried to persuade him to leave, but he wouldn’t li sten.我想劝他离开，可他不听。

注意：promise sb to do sth

该结构中的不定式的逻辑主语不是其前的宾语sb，而是句子主语，所以严格说来，此句中的不定式不是宾语补足语，如He promised me to go.的意思是“他答应我他去”，而不是“他答应让我去”。

不定式用法详解

不定式用法详解 定义：在句子中充当除了谓语以外的各种句子成分的动词形式叫做非谓语动词。 非谓语动词有三种：不定式，动名词，分词。 注：非谓语动词具有时态和语态的变化，可以同否定词not连用，构成否定形式，可以带宾语，状语，补语。非谓语动词的名词，形容词，副词的特征；可用在句中做主语，宾语，补语，状语，和定语等。 —不定式（原形动词前加to, 构成动词不定式。不定式不做谓语，属于非谓语动词） 不定式的时态，语态 一般式：不定式所表示的动作和谓语动词所表示的动作或状态同时发生或几乎同时发生或存在。但多数情况下是在谓语动词所表示的动作之后发生。 e.g :They often watch us play football. (同时) She hopes to go there again. (之后发生) 完成式：不定式所表示的动作或状态发生在谓语动词所表示动作或状态之前。 e.g : I’m glad to have seen your mother yesterday 注：1）用在intended, expected, meant, hoped. promised, wanted, planned. wished. thought, desired, was, were等后，表示过去没有实现的愿望，期待或计划的等，也用来表示先于谓语动词发生的动作或状态。 e.g: He wanted to have met (=had wanted to meet) you at the airport,but he didn’t get there in time. 他原想去机场接你（事情已经发生），但他没及时赶到那儿。（没接成） e.g: We planned to have done (had planned to do) good deeds for the poor people last month. 我们原计划上个月为贫困的人们作些好事。（没作成）。

动词不定式练习题及讲解说课讲解

动词不定式练习题及 讲解

动词不定式用法要点讲解 一、作主语 动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种： (1)把不定式置于句首。如： To get there by bike will take us half an hour. (2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。如： ①It＋be＋名词＋to do It's our duty to take good care of the old. ②It takes sb+some time+to do How long did it take you to finish the work? ③It＋be＋形容词＋for sb＋to do It is difficult for us to finish writing the composition a quarter of an hour. ④It＋be＋形容词＋of sb＋to do It is stupid of you to write down everything the teacher says. ⑤It seems(appears)＋形容词＋to do It seemed impossible to save money. 二、作宾语 ⒈不定式作宾语 ①以下动词后，只能跟不定式作宾语。如： agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,long manage,offer,plan,prepare,pretend,promise,refuse,wish等，这些词大部分可接 th at引导的从句。如： When our visit to the farm was over, we expected to start back on foot. When our visit to the farm was over, we expected that we would start back on foot. ②当复合宾语中的宾语是不定式时，先用形式宾语it代替不定式，把不定式置于补语之后，即：主语＋动词＋it＋补语＋to do句式。 He feels it his duty to help the poor. ③介词but,except,besides+to do(do) 在这种句型中，如介词前有动词do，后面应接不带to的不定式；如无do，则接to 不定式，即带do不带to，带to不带do。如： The enemy soldiers had no choice but to give in. ⒉部分动词后面，既可接动词不定式，也可接动名词作宾语，意义不变。如：begin,continue,start,hate,like,love,need,require,want等。 在need,require,want后接-ing形式，表示被动意义，也可接不定式，但要用被动形式，如：Your handwriting needs improving(tobe improved). hate,love,like接不定式表示特定的未来事件，接动名词表示目前正在进行的活动或一般的行为。 在下列情况下，一般要用不定式： ①hate,like,love前有would(should)时，如：I'd like to have a cup of coffee. ②当谓语动词begin,continue,start等是进行式时，如：Thestudents are starting to work on the difficult maths problem. ③begin,continue,start与know,understand等状态动词连用时，如：I soon began to understand what was happening. 3．advise,allow,encourage,forbid,permit等动词后接动名词作宾语，或带不定式作宾语补足语。如： Our teachers don't permit our/us swimming in the lake. Our teachers don't permit us to swim in the lake. 4．部分动词后接不定式或动名词时，意义差别较大，应根据句子语境选择使用。 ①forget,remember,regret后接不定式，表示现在或未来的动作，接动名词表示动作已经发生。如： We regret to tell you that all of you are not invited to attend the meeting. They regretted ordering these books from abroad. ②mean to do 打算做某事 ;mean doing 意味着…… ③try to do 设法尽力做某事; try doing 试着做某事 ④stop to do 停下一件事去做另一件事（不定式作目的状语）; stop doing 停止做某事 ⑤can't help doing 禁不住…; can’t to do不能帮助干…… ⑥go on to do 做不同的事或不同内容的事; doing 继续不停地做某事，指同一动作的继续 ⑦leave off to do 离开某地去干什么（目的状语）; leave doing停下某事 三、做表语 To be kind to the enemy is to be cruel to the people. 四、作定语 不定式在句中作定语，置于被修饰的名词或代词之后。如： Have you anything to be taken to your sister? 收集于网络，如有侵权请联系管理员删除

不定式用法讲解

高中英语语法讲解不定式 （The Infinitive） 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。 E.g. He want his students to read the book aloud. A． 1 2 不定式的意义 不定式的一般式(to do ) 一般式表示的动作或状态，发生在谓语动词表示的动作或状态的同时或之后My wish is to become a doctor He seemed to be tired. She stopped to have a rest. 不定式的被动式 (to be done) 当不定式的逻辑主语是这个不定式所表示的动作的承受者时,不定式一般要用被动式. The building to be finished next month is for our teachers. I am going to Beijing, I have something to take to my parents, do you have something to be taken to your parents? 如果谓语表示的动作(情况)发生时, 不定式表示动作正在进行,这时候不定式就要用进行式.（to be doing） They are said to be building another bridge across the street. They seemed to be talking about something important. When I went to his home, he happened to be traveling around the world. I’m glad to be working with you. 如果不定式所表示的动作或状态发生在谓语动词所表示动作或状态之前，就用完成式 (to have done) ；若是在此基础上的被动含义，就用完成被动式( to have been done). He is said to have written a novel about the Long March. He thought it a pity not to have invited us. The assistant seemed to have been fired. He is said to have been taught French when he was a child. Einstein is said to have built up his theory when he was in his twenties. 如果不定式的动作是在谓语所表示的时间之前一直在进行的动作，就要用完成进行式. They are said to have been collecting folk song in Xinjiang. We’re happy to have been working with the experts all the month.

有关to do不定式的,to do不定式什么时候可以省略to do;还有什么时候用被动形式,什么时候不用。

2014年8月4日 17:10 有关to do不定式的，to do不定式什么时候可以省略to do；还有什么时候用被动形式，什么时候不用。 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：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 everything. 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 twenty hours a day. 正：He was made to work twenty hours a day. 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： They forced her to sign the paper.他们强迫她在文件上签字。 The law obliged parents to send their children to school. 法律要求父母送子女上学。 二、感觉动词与to的省略 当不定式用于表示感觉的动词feel, hear, notice, observe, see, watch, look at, listen to等作宾语补足语时，不定式必须省略to。如： We all felt the house shake. 我们都感觉这房子在震动。 I heard him go down the stairs. 我听见他下楼了。 Did you notice her leave the house? 她离开屋子你注意到了吗? I watched her get into the car. 我看着她上了车。 但是，当feel后用作宾语补足语的不定式为to be时，则不能省略to。如： They all felt the plan to be unwise. 他们都认为这个计划不明智。 注意，当这些动词变为被动语态时，不定式前的to不能省略。如： They were heard to break a glass in the next door. 听见他们在隔壁打破了一个玻璃杯子。 另外，若用作宾语补足语的不定式为完成式，则通常应带 to。如： I noticed her to have come early. 我注意到她来得很早。 三、why (not) 与to的省略 在why (not)…?之后的不定式不能带to。如： Why argue with him? He’ll never change his mind. 为什么要跟他争论? 他永远不会改变 自己的看法。 Why not try going by boat for a change? 为什么不试着坐船去，这样也可以换换花样? Why not wait till the winter sales to buy a new coat? 为什么不等到冬季大贱卖时再买一件新外衣呢? 四、介词except / but与to的省略 当不定式用作介词except或except的宾语时，该不定式有时带 to，有时不带 to，情形比较复杂，大致原则是：其前有do，不定式不带 to；其前没有 do，不定式通常带to。如： He likes nothing except to watch TV. 除了看电视外，他什么都不喜欢。 It had no effect except to make him angry. 除惹他生气外，没产生任何效果。

M5U1语法——动词不定式【附练习题+答案】

M5U1语法——动词不定式【附练习题+答案】动名词的构成形式 动词不定式是由“to + 动词原形”构成；动名词由动词+ing构成。 主动式有：一般式、进行式、完成式和完成进行式； 被动式有：一般式、进行式和完成式。 动词不定式、动名词用法要点讲解 一．做主语 ⒈不定式作主语 动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种： (1)把不定式置于句首。如： To get there by bike will take us half an hour. (2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。如： ① It＋be＋名词＋to do It's our duty to take good care of the old. ② It takes sb. + some time + to do How long did it take you to finish the work?

③ It＋be＋形容词＋for sb.＋to do It is difficult for us to finish writing the composition in a quarter of an hour. ④ It＋be＋形容词＋of sb.＋to do It is stupid of you to write down everything the teacher says. ⑤ It seems(appears)＋形容词＋to do It seemed impossible to save money. 在句型③中，常用表示客观情况的形容词，如：difficult, easy, hard, important, impossible, necessary 等； 在句型④中，常用careless, clever, good, foolish, honest, kind, lazy, nice, right, silly, stupid, wise 等表示赞扬或批评的词。在不定式前的sb.，可看作其逻辑主语。这一句式有时相当于sb. is ＋形容词＋to do句式，如： It's kind of you to help me with my English. =You are kind to help me with my English. ⒉动名词做主语 Learning without practice is no good. 动名词做主语时，也常用It句式。如： ①It's +no good(no use, fun, a pleasure, a waste of time)+doing… It's no good reading in dim light. It's no use sitting here waiting. ② It's＋形容词＋doing It's dangerous swimming in the sea in windy days. 这样用的形容词有expensive, nice, tiring等，但important, necessary则不适用于这种结构，应用不定式代替，如：It's important for you to keep fit. ③ There is no + doing There is no saying what will happen next. There is no denying that he has stolen the bike. 在这一结构中，动名词后常带宾语，相当于"It's impossible to…"结构。 ⒊动词不定式和动名词作主语的区别 ①不定式作主语经常表示具体动作，常与特定的动作执行者联系在一起；而动名词作主语经常表示抽象动作，经常不与特定的动作执行者联系在一起。如： It's no good eating too much fat. It's no good for you to eat so much fat. ②动名词结构作主语，可以用名词或代词属格形式作逻辑主语。如： It's no use your pretending that you didn't know the rules. 二、作宾语 ⒈不定式作宾语 ①以下动词后，只能跟不定式作宾语。如：agree, ask, aim, arrange, choose, decide, demand, expect, fail, help, hope, lean, long, manage, offer, plan, prepare, pretend, promise, refuse, wish等，这些词大部分可接that引导的从句。如： I decided to ask for my money back. I decided that I would ask for my money back.

动词不定式用法讲解

动词不定式用法讲解 1、构成及特征 动词不定式(infinitive)是动词的一种非限定形式，即非谓语动词形式，它有两种形式：一种是“to + 动词原形”构成（to- infinitive）；另一种是不带to的不定式,即动词原形(bare- infinitive)。所有行为动词都有不定式形式，其否定式是在不定式前加not。动词不定式（或不定式短语）没有人称和数的变化，在句子中不能作谓语。动词不定式仍保留有动词的特点：（1）可以有时式和语态的变化，也可以有自己的宾语或状语，它们一起构成了不定式短语。He tried to work out the problem in five minutes.他试图在五分钟之内算出这道题。（带宾语和状语） The factory to be built here next year is a car factory.明年在这里建的工厂是一家汽车制造厂。（有语态的变化） （2）动词不定式还具有名词、形容词和副词的特征，在句中可以作主语、宾语、表语、补语、定语、状语等成分。 He wants to study English.他想学英语。（to study English在句中作want的宾语，而to study又有自己的宾语English, to study和English一起构成了不定式短语。）Never to offend anyone is his principle.不得罪人是他的原则。（不定式作主语） 注意：不定式在许多场合具有情态意义。作主语时，相当于一个带有情态动词的主语从句；作宾语时，相当于一个带有情态动词的宾语从句；作定语时，相当于一个带有情态动词的定语从句；作目的状语时，相当于so that 或in order that引导的目的状语从句。 It is right for her to say so.(= It is right that she should say so.)她这样说是对的。 He has a lot of work to do.(=…that he should do)他有很多工作要做。 I don’t know where to get the ticket.(= …where I could get the ticket.)我不知道哪

(完整版)省略to的动词不定式用法归纳

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： 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 everything.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 twenty hours a day. 正：He was made to work twenty hours a day. 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： They forced her to sign the paper.他们强迫她在文件上签字。 The law obliged parents to send their children to school.法律要求父母送子女上学。 考例： 1.The teacher forbade ________ our seats. https://www.sodocs.net/doc/6216100170.html, to leave https://www.sodocs.net/doc/6216100170.html, leaving C.to leave D.to leaving 2.Mary had her friend ________ the best one. A.choose B.chosen C.chose D.to choose 3.The girl was ma de _________ she didn’t love at all. A.marry a man B.to marry a man C.to marry with a man D.married with a man 二、感觉动词与to的省略 当不定式用于表示感觉的动词feel, hear, notice, observe, see, watch, look at, listen to等作宾语补足语时，不定式必须省略to。如： We all felt the house shake.我们都感觉这房子在震动。 I heard him go down the stairs.我听见他下楼了。 Did you notice her leave the house?她离开屋子你注意到了吗? I watched her get into the car.我看着她上了车。 但是，当feel后用作宾语补足语的不定式为to be时，则不能省略to。如：They all felt the plan to be unwise.他们都认为这个计划不明智。 注意，当这些动词变为被动语态时，不定式前的to不能省略。如： They were heard to break a glass in the next door.听见他们在隔壁打破了一个

初中英语动词不定式讲解试题和答案

初中英语动词不定式讲解试题和答案 一、作主语，可以用it代替，it叫形式主语，动词不定式放在后面叫真正主语 1．To learn a foreign language is not easy. It is not easy to learn a foreign language. 2. It’s dangerous to drive very fast. 二、作表语 My idea is to ring him up at once. 我的想法是马上给他打电话。 如果主语部分含实义动词do，且作表语的动词又是“do”的内容，这时表语不定式的“to”可以省略。如：All I did was wait here. 我能做的就是在这里等。 三、常可接动词不定式作宾语的动词有：agree(同意), hope(希望), decide(决定), need(需要), mean(打算), wish(希望), fail(失败), want(想要), begin(开始), would like(想要)等。 He has decided to go to the countryside. 他已决心去乡下。 四、“疑问词+ 动词不定式”结构可以作动词know、think、find out等的宾语。 I don’t know who to ask. 我真不知道该问谁。 五、“疑问词+ 动词不定式”可以作动词show、teach、ask等后面的直接宾语。 She told me where to find the earphone. 她告诉我什么地方可以找到耳机。 六、如果宾语太长，可用it作形式宾语，构成“主语+ 谓语+ it + 宾语不足语(名词或形容词) + to do sth”结构，谓语动词常为find、think、feel等。 I found it difficult to stop him. 我发现拦截他很困难。 七、动词不定式可以作介词的宾语。 Autumn harvest is about to start. 秋收即将开始。 I’m worrying about what to do next.我正愁下一步该怎么办。 八、作定语的动词不定式与被修饰词有动宾关系。

九种不定式省略to的情况

句子成分 句子主要有以下几种成分： 1）主语（subject）是一句话的中心，整句话都在谈它的情况：my sister is a nurse. Her room is on the 5th floor. 2）谓语（predict）是主语的主要情况，可以表示动作，也可以表示状态：she works in a hotel.(动作) she knows a little English.（状态） 3）宾语（object）表示动作的承受者，也可以表示动作的结果：Everybody likes her. She is writing a letter now. 4）表语（predicative）和系动词一道构成谓语：she is conscientious girl.她是一个工作认真的女孩。 5）定语（attributive）修饰名词，代词等： Her hospital is not very big. But everyone in the hospital works hard.. 6）状语（adverbial）修饰动词，形容词或者副词：She goes to work very early. She feels very happy 此外还有同位语（appositive）插入语（parenthesis）以及呼语（vocative）This is my sister Mary. Mary is good girl, they say Sit down, Mary 句子的类型 1）按照说话的目的分为四类： A．陈述句（statement）: 陈述一个事实，表示一个看法等：Beijing is the capital of China She may be right. B．问句（question）: 提出问题： Where are you from? C．祈使句（imperative）提出命令请求等。 Don’t be late again. Take a seat, please. D．感叹句（exclamation）表示赞美惊异等情绪： W hat a nice view from the window! 2）从结构上来区分又可以分为三类： a简单句 如果一个句子只包含一个主谓结构，而句子各个成分都只用单词或短语表示,它就是简单句。 I live in the country. The teachers and students cheered at the news. 简单句主要由五种基本句型构成，千千万万的句子变化可以看作是这五种基本句型的扩展、省略、组合和倒装。 基本句型一：主语+谓语（不及物） The baby smiled. The teacher came in, followed by some students. 基本句型二：主语+谓语（系）+表语。
