高中英語(yǔ)語(yǔ)法講解不定式
（The Infinitive）
定義：動(dòng)詞不定式是非謂語(yǔ)動(dòng)詞的一種，它沒(méi)有人稱(chēng)和數(shù)的變化，在句子中不能獨(dú)立作謂語(yǔ)，但它仍保持動(dòng)詞的特點(diǎn)，既可以有自己的賓語(yǔ)和狀語(yǔ)。 E.g. He want his students to read the book aloud.
A．
1不定式的構(gòu)成 （以動(dòng)詞do為例）
主動(dòng)形式 被動(dòng)形式
一般式 to do to be done
完成式 to have done to have been done
進(jìn)行式 to be doing 無(wú)
完成進(jìn)行式 to have been doing 無(wú)
2?不定式的意義
不定式的一般式(to do )
一般式表示的動(dòng)作或狀態(tài)，發(fā)生在謂語(yǔ)動(dòng)詞表示的動(dòng)作或狀態(tài)的同時(shí)或之后
My wish is to become a doctor
He seemed to be tired.
She stopped to have a rest.
不定式的被動(dòng)式 (to be done)
當(dāng)不定式的邏輯主語(yǔ)是這個(gè)不定式所表示的動(dòng)作的承受者時(shí),不定式一般要用被動(dòng)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?
如果謂語(yǔ)表示的動(dòng)作(情況)發(fā)生時(shí), 不定式表示動(dòng)作正在進(jìn)行,這時(shí)候不定式就要用進(jìn)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動(dòng)作或狀態(tài)發(fā)生在謂語(yǔ)動(dòng)詞所表示動(dòng)作或狀態(tài)之前，就用完成式 (to have done) ；若是在此基礎(chǔ)上的被動(dòng)含義，就用完成被動(dòng)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.
如果不定式的動(dòng)作是在謂語(yǔ)所表示的時(shí)間之前一直在進(jìn)行的動(dòng)作，就要用完成進(jìn)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.
B. 用法：
動(dòng)詞不定式具有名詞、形容詞和副詞的特征。因此在句中可以做主語(yǔ)、表語(yǔ)、賓語(yǔ)、賓語(yǔ)補(bǔ)足語(yǔ)、定語(yǔ)和狀語(yǔ)。
一、不定式做主語(yǔ)：
1、不定式做主語(yǔ)一般表示具體的某次動(dòng)作。===動(dòng)名詞doing 表示習(xí)慣的，經(jīng)常的動(dòng)作。
e.g: To finish the building in a month is difficult.
To do such things is foolish.
To see is to believe. (對(duì)等)
注: 1). 不定式作主語(yǔ)時(shí),謂語(yǔ)用單數(shù)
2). 當(dāng)主語(yǔ)較長(zhǎng)，謂語(yǔ)較短時(shí)，常用it做形式主語(yǔ)，而將不定式放到謂語(yǔ)的后面。
it做形式主語(yǔ)，不定式放在謂語(yǔ)動(dòng)詞之后常用于下列結(jié)構(gòu)中：
(1)It is/was +adj.+of sb. to do…
(2) It is +adj.+for sb.+to do…
It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary
(3) it is +a +名詞+ to do...
It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do
It takes (sb.) some time / courage / patience …to do…
It requires courage / patience / hard work… to do…
*注意: probable 和 possible 均可作表語(yǔ)，但possible可以用不定式作真實(shí)主語(yǔ)， 而probable不能用不定式作真實(shí)主語(yǔ)。
It is probable for him to come to the meeting.(錯(cuò)）
It is possible for him to come to the meeting.
It is possible / probable that he will come to the meeting.
二、不定式做表語(yǔ)
主語(yǔ)是以aim duty hope idea intention plan job suggestion wish purpose task 等為中心詞的名詞詞組 或以 what 引導(dǎo)的名詞性從句表示，后面的不定式說(shuō)明其內(nèi)容, 不定式作表語(yǔ)常表示將來(lái)或現(xiàn)在的動(dòng)作或狀態(tài)。
eg My idea is to climb the mountain from the north.
Your mistake was not to write that letter.
What I would suggest is to start work at once.
三 動(dòng)詞不定式作賓語(yǔ)
以不定式結(jié)構(gòu)為賓語(yǔ)的動(dòng)詞有：
ask, agree, care, choose, demand, decide, expect, fail, help, hope, learn, manage, offer, plan, prepare, pretend, promise, refuse, want, wish等只能用動(dòng)詞不定式作賓語(yǔ)
口訣（接不定式作賓語(yǔ)的動(dòng)詞）
想要學(xué)習(xí) 早打算（ want learn plan）
快準(zhǔn)備 有希望（ prepare hope wish expect）
同意否 供選擇（agree offer choose）
決定了 已答應(yīng)（decide be determined promise）
盡力去 著手做（manage undertake）
別拒絕 別假裝（refuse pretend）
失敗不是屬于你（fail）
e.g.Tom refused to lend me his pen.
We hope to get there before dark.
The girl decided to do it herself.
*注意:某些及物動(dòng)詞可用-ing也可用動(dòng)詞不定式作賓語(yǔ)但意義不同的有
stop go on remember forget
regret try mean can’t help
be used to
四． 動(dòng)詞不定式做定語(yǔ)
1．. 不定式作定語(yǔ)需要后置。
2. 作定語(yǔ)的不定式與被修飾的名詞或代詞存在著兩種主要的邏輯關(guān)系，即被修飾的名詞和代詞是不定式的邏輯主語(yǔ) （邏輯上的主謂關(guān)系）或邏輯賓語(yǔ)（邏輯上的動(dòng)賓關(guān)系）
1）不定式前的名詞是它的邏輯主語(yǔ)。
He is the doctor to do the operation.
2) 不定式和它所修飾的名詞是邏輯上的動(dòng)賓關(guān)系。
I have a lot of things to do.
3）不定式前的名詞是它修飾的對(duì)象。
This is the right time to start.
注意．如果不定式所修飾的詞是way 或 place, 介詞可省略。
He has no way to go (by). This is the best place to work (at)
五．賓語(yǔ)補(bǔ)足語(yǔ)
He want you to be his assistant. I saw her cross the street.
[注1] 如果謂語(yǔ)動(dòng)詞為感官動(dòng)詞或使役動(dòng)詞，則作賓補(bǔ)的不定式不可帶to，這些動(dòng)詞有see, hear, feel, watch, notice; have, make, let等。
I felt my blood run cold. What made you think like that?
但如果句子是被動(dòng)語(yǔ)態(tài)，則to不可省略。
He was made to clean the windows as a punishment.
Someone was heard to come up the stairs.
[注2] 1.謂語(yǔ)動(dòng)詞help后可接帶to或不帶to的不定式作賓補(bǔ)。用不帶to的不定式表示幫助者直接參與動(dòng)作；用帶to的不定式表示主語(yǔ)沒(méi)有直接參與動(dòng)作。
They helped me carry the boxes.
This kind of soap will help you to wash the clothes more easily.
2.在美式英語(yǔ)或非正式文體中，help后用作賓補(bǔ)的不定式均不帶to。
3.help后可以直接用帶to或不帶to的不定式作賓語(yǔ)。
They helped (to) carry the furniture upstairs.
[注3]look at及l(fā)isten to后用作賓補(bǔ)的不定式不帶to（這主要是美式英語(yǔ)）。
We have been listening to the radio tell a long story.
六 ．表語(yǔ)補(bǔ)足語(yǔ) 當(dāng)不定式與主語(yǔ)存在邏輯上動(dòng)賓關(guān)系的時(shí)候，用主動(dòng)表被動(dòng)。
That is hard to say. The chair is comfortable to sit in.
七． 不定式做狀語(yǔ)
不定式做狀語(yǔ)修飾動(dòng)詞、形容詞、副詞等，表示目的、原因、結(jié)果、 條件等。
1、表目的 e.g. To learn a foreign language well, you must try your best (主語(yǔ)一致)
He came here to attend an important meeting.
He came here in order to see Charlie.
I turned the radio down so as not to disturb him
注：表示目的的不定式可以置于句首，這也是區(qū)別于 其他功能的標(biāo)志之一。
* 但是，置于句首表示目的的不定式可以是to, in order to ，但卻不可以是so as to. ”,” To draw maps properly, you need a special pen.
In order to draw maps properly, you need a special pen.
To get the best results, use clean water.
To be elected monitor of our class, he gave money to us.
* 放在句末時(shí)， to do 表示目的， 不可有“，”若有用doing 表示伴隨的目的
e.g. He bowed to us to thank us for helping him find the way.
He worked day and night, hoping to finish the work beforehand.
注：1. 不定式結(jié)構(gòu)表示目的時(shí)，通常句子的主語(yǔ)就是它的邏輯主語(yǔ) (主語(yǔ)一致)
e.g.He bought a bicycle to go to town more quickly.
He went home to see his mother.
例外 e g He opened the door for the children to come in.
They sent a man to mend the window.
2、表結(jié)果
不定式結(jié)構(gòu)表示結(jié)果更常見(jiàn)于下列句型
① so …as to …
Would you be so kind as to lend me your bicycle / tell me the time?
② such (…) as to …
I’m not such a fool as to believe that.
③ adj./adv. + enough to …
The boy is old enough to go to school.
④ too … to …
His eyesight is too poor to read such small letters.
（5）only to find , only to be told 出乎意料之外的結(jié)果
3． 原因不定式可以用于動(dòng)詞、形容詞或-ed分詞后表示原因。
He was too excited to get high marks.
八．同位語(yǔ)
Is this your purpose, to avoid being punished?
九．獨(dú)立成分
To tell you the truth, I don’t like you. They arrived here at 11:55 a.m., to be exact.
類(lèi)似的有：to be frank坦率地說(shuō)，to hear him talk聽(tīng)他說(shuō)話(huà)的口氣，to cut a long story short 長(zhǎng)話(huà)短說(shuō)，等等。
C
不定式的各種結(jié)構(gòu)
1．賓格詞 + 不定式
1）普通結(jié)構(gòu) 此結(jié)構(gòu)中的賓格詞為名詞或代詞的賓格，賓格詞是謂語(yǔ)動(dòng)詞的賓語(yǔ)，同時(shí)又是不定式的邏輯主語(yǔ)，不定式和賓格詞一起構(gòu)成復(fù)合賓語(yǔ)。
I want Henry to come. She expects this to be true. I heard them sing yesterday.
2) “there to be + 賓格詞”結(jié)構(gòu)
此結(jié)構(gòu)的賓格詞仍是不定式的邏輯主語(yǔ)，只是它位于不定式to be 的后面。
I don’t want there to be any misunderstanding.
3) 各種形式的不定式都可以用于此種結(jié)構(gòu)中。
The judge wanted the man to be punished.
He expected each of his students to be working hard for the coming exam.
2．主格詞 + 不定式
當(dāng)上一種結(jié)構(gòu)變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí)，就出現(xiàn)了此種結(jié)構(gòu)，此結(jié)構(gòu)中，不定式都要帶to，主格詞是不定式的邏輯主語(yǔ)，不定式在句中作主語(yǔ)補(bǔ)足語(yǔ)。
They are allowed to go. ← We allowed them to go.
He was seen to enter the store. ← I saw him enter the store.
3．for + 賓格詞 + 不定式
此結(jié)構(gòu)中，賓格詞是不定式的邏輯主語(yǔ)，這種結(jié)構(gòu)在句中可作：
1） 主語(yǔ) It is difficult for us to learn a second foreign language.
2）賓語(yǔ) I consider it necessary for her to learn French.
3）表語(yǔ) The best thing is for us to make our own decision.

5．疑問(wèn)詞 + 不定式 此結(jié)構(gòu)相當(dāng)于名詞詞組，在句中可作：
1） 主語(yǔ) When to visit that farm has not been decided yet.
2） 賓語(yǔ) We must know how to operate this machine.
3） 表語(yǔ) The problem now is how to collect enough money.
4） 同位語(yǔ) The problem what to do next is unknown.
注意 intend, plan, hope, expect, mean, promise, want, think, wish, were (was), would like, should like + 不定式完成式，可表過(guò)去沒(méi)有實(shí)現(xiàn)的愿望，期待和計(jì)劃。

F
常見(jiàn)的含有動(dòng)詞不定式的句式主要有以下幾種：
一.
It takes sb. some time （money）to do sth.
某人花費(fèi)多少時(shí)間（金錢(qián)）做某事。例如：
1. It often takes me half an hour to watch TV every evening.
每天晚上我常常用半小時(shí)看電視。
2. It took me ten yuan to buy the book last week.
上周我花了10元買(mǎi)那本書(shū)。
3. How long will it take them to finish the work?
完成那項(xiàng)工作需要花費(fèi)他們多少時(shí)間？
在使用該句式要注意的是：sb. 如果代詞表示用賓格；take隨時(shí)態(tài)改變；句中的時(shí)間用段時(shí)間，對(duì)此提問(wèn)用how long。
例：It takes us more than two hours to do our homework every day.
It took us more than two hours to do our homework yesterday.
It will take us more than two hours to do our homework tomorrow.
How long did it take you to do your homework yesterday?
二. It’s time to do sth. 該做某事了，同義句為：
It’s time for sth. / doing sth. 例：
It’s time to go to school. 該上學(xué)了。
（It’s time for school.）
It’s time to get up. 該起床了。
（It’s time for getting up.）
此句可以擴(kuò)展為：It’s time for sb. to do sth.
是某人做某事的時(shí)間了。
for sb. to do sth. 是動(dòng)詞不定式的復(fù)合結(jié)構(gòu)。例：
It’s time for me to work.
到我工作的時(shí)間了。
It’s time for you to go to school.
到你們上學(xué)的時(shí)間了。
三. 主語(yǔ)＋be（not）+adj.+enough to do sth.
（某人、某物）足夠（不能）做某事。例：
The boy is old enough to go to school.
這個(gè)孩子到了上學(xué)年齡。
I’m tall enough to reach the top of the tree.
我夠高能夠到樹(shù)頂。
*1. 此句是肯定句時(shí)，可以用主＋be＋so＋adj.＋that的句型（即so…,that…表示的結(jié)果狀語(yǔ)從句）來(lái)替換。
The boy is so old that he can go to school.
I’m so tall that I can reach the top of the tree.
2. 此句是否定句式時(shí)，既可以用so…that…引導(dǎo)的結(jié)果狀語(yǔ)從句來(lái)替換，還可以用too…to…句式替換。例：
He is not old enough to go to work.
他太小不能去上班。
He is so young that he can’t go to work.
He is too young to go to work. 再如：
The box is not light enough for me to carry.

The box is so heavy that I can’t carry it.
四. sb. +be ready + to do sth. （某人樂(lè)意做某事）
He is always ready to help others.
（他總是樂(lè)于幫助別人）
I’m always ready to make new friends.
我總是樂(lè)于結(jié)交新朋友。
五. It’s +adj. + for / of sb. to do sth.
對(duì)某人來(lái)說(shuō)做某事…例：
It’s dangerous for children to play football in the street.
對(duì)孩子來(lái)說(shuō)在街上踢足球是很危險(xiǎn)的。
It’s good for us to take more exercise.
對(duì)我們來(lái)說(shuō)多運(yùn)動(dòng)是有益的。
It’s very kind of you to say so.
你這樣說(shuō)真是太好了。
It’s very kind of you to help me.
你真好，肯幫我。
該句式中，引導(dǎo)動(dòng)詞不定式的邏輯主語(yǔ)的介詞用for還是of，主要取決于前面的形容詞。如果形容詞是描述動(dòng)詞不定式的行為者的性格、品質(zhì)的。如：kind, good, nice, wrong, right, clever, careless, foolish等，應(yīng)用of；如果形容詞僅僅是描述事物，不是對(duì)動(dòng)詞不定式的行為者的品質(zhì)進(jìn)行評(píng)價(jià)的，就用for. 常見(jiàn)這類(lèi)形容詞有difficult, easy, hard, important, dangerous等。
It’s wrong of you to do it.
你做這件事是錯(cuò)的。
It’s hard for you to be a lawyer.
對(duì)你來(lái)說(shuō)做律師很困難。

It’s very cold outside, you’d better put on your coat.
外面很冷，你最好穿上大衣。
We’d better go right now.
我們最好馬上去。
…had better do 的否定式為…had better not do. （在better后加not即可）例：
You’d better not speak when your mouth is full of food.
滿(mǎn)嘴食物時(shí)你最好別講話(huà)。
八. Why don’t you +動(dòng)詞原形+…？（Why not＋動(dòng)詞原形…？）你為什么不…？
這本書(shū)有點(diǎn)難，為什么不讀些容易的？
This book is a bit hard, why not read something easier?
It’s warm here, why don’t you take off your coat?
這很暖和，你為什么不脫掉外衣？
There is a seat, why not sit down?
還有座位，怎么不坐下？
九. Would / Will / Could you please ＋動(dòng)詞原形＋…？
請(qǐng)你…好嗎？（用來(lái)請(qǐng)求對(duì)方為自己做某件事）

解析：
1．tell sb. not to do sth告訴某人不做某事
2．take sth for granted “把某事想當(dāng)然”， 是一個(gè)固定詞組。Eg. You shouldn’t take it for granted that everyone should help you.你不要認(rèn)為每個(gè)人都理應(yīng)幫助你。
4. 不定式的省略要保留到to,否則就完整地表達(dá)， 如:…but his mother told him not to do so.
5. warn sb not to do sth. 此處用never替代not.
8. allow sb to do sth允許某人做某事；risk doing sth冒險(xiǎn)做某事
9. see sb do sth看見(jiàn)某人做某事
12. make sb do 讓某人做某事， 但用于被動(dòng)結(jié)構(gòu)后， 則要用不定式符號(hào)to連接。
16．which 用于有范圍中的“哪一個(gè)”， 此處作buy的賓語(yǔ)。
18．when +to do 做decide的賓語(yǔ)， 若用when引導(dǎo)賓語(yǔ)從句，用陳述句語(yǔ)序。
21. pretend to do 假裝做某事。
22．forget to do sth忘記（要）做某事。
24．should love to be taken to …愿意被帶去……
25．因?yàn)闋钫Z(yǔ)是last night，用不定式的完成式表示本想……
27. go on to do sth. 繼續(xù)做（與原來(lái)不相同的）事。此句可以從the other exercise 斷 定。
28．stop to do sth. 停下來(lái)（去）做……
32．被動(dòng)語(yǔ)態(tài)后用不定式連接，根據(jù)句意用完成式。
33. would rather not do sth. 寧愿不做某事。
34. prefer to do sth. rather than do sth. 寧愿做……不愿做……
37．to eat 此處作something 的定語(yǔ)。for+doing多表用途。
38. why not do sth…“為什么不……” ；try doing sth試一試
39．Do nothing but do sth, 此處用except替代but
40. spare sb. sth勻出、騰出……， 賓語(yǔ)為sb.； share分享， 賓語(yǔ)為sth.
41. let sb do, 此處用的是被動(dòng)語(yǔ)態(tài)
42． get sth. done讓某事被做
44．tired此處是過(guò)去分詞， 表示主語(yǔ)的狀態(tài)。only to learn…此處的不定式表結(jié)果。
45．此處的to find it, 表示目的
47. to eat at the restaurant, 介詞at不能丟
