【高考英語】不定式做句法成分
不定式短語作主語時,可以直接放在句首,但在很多情況下,尤其是在疑問句和感嘆句中,往往放在謂語之后,而用先行代詞it作形式主語。不定式由“ to十動詞原形”構(gòu)成,其否定形式是“ not to do”。不定式可以帶賓語或狀語構(gòu)成不定式短語,沒有人稱和數(shù)的變化,但有時態(tài)和語態(tài)的變化.不定式可作主語、賓語、狀語、表語和定語,但不能單獨(dú)作謂語.不定式的邏輯主語有時用“ for十名詞或代詞賓格”構(gòu)成。
1.不定式作主語
To see is to believe.
常用it作形式主語
It's for sb/It's of sb
1)for sb. 常用于表示事物的特征特點,表示客觀形式的形容詞,如easy, hard, difficult, interesting, impossible等:
It's very hard for him to study two languages.
2)of sb的句型一般用表示人物的性格,品德,表示主觀感情或態(tài)度的形容詞,如good, kind, nice, clever, foolish, cruel, right。
It's very nice of you to help me
To serve the people is my great happiness. 為人民服務(wù)是我的最大幸福。
It is right to give up smoking.戒煙是對的。
不定式作主語常見句型如下:
a.It is + adj (easy, important, difficult…) + 不定式
b. It is + n (a pity, a pleasure, one’s duty, a shame) + 不定式
c. It takes/needs/requires + some time (hours, months, days, patience…) + 不定式
It’s important for us to learn English well. 我們學(xué)好英語很重要。
It’s my duty to teach you how to be a useful person. 教你如何做一個有用的人是我的職責(zé)。
It requires patience to be a good teacher. 當(dāng)個好老師需要耐心。
【高考英語】不定式作賓語
不定式短語作賓語時,位于及物動詞之后??梢灾苯佑貌欢ㄊ阶髻e語的動詞很多,常見 的有:agree, afford, tend, ask, decide, determine, expect, fail, hope, learn, intend, manage, offer, plan, promise, refuse, want, wish等。例如:
I offered to help her, but she refused. 我提出幫助她,但她拒絕了。
He pretended not to hear me. 他假裝沒聽見我(的聲音)。
I don’t want to sound like I’m speaking ill of anybody, but the manager’s plan is unfair.
我不想聽起來象在說別人壞話,但經(jīng)理的計劃是不公平的。
如果還帶有賓語補(bǔ)足語。往往把不定式賓語放在賓語補(bǔ)足語之后,而用 it作形式賓語。常用動詞有feel, think, find, believe, consider, make等。例如:
I find it interesting to work with him. 我發(fā)現(xiàn)與他共事很有趣。
We feel it our duty to help others. 我們認(rèn)為幫助別人是我們的責(zé)任。
Science and technology has made it possible for man to fly in space.科學(xué)技術(shù)已經(jīng)使人類能夠遨游太空了。
下列動詞后可接疑問詞+不定式:
teach、decide、wonder、show、learn、forget、ask、find out、advise、know等
例如:
Can you teach me how to use the computer 你能教我使用電腦嗎
I don’t know what to do next. 我不知道下一步怎么辦。
I want to speak to Tom.
Please show us how to do that.
【高考英語】不定式作賓補(bǔ)
不定式作賓語補(bǔ)足語位于賓語之后,表示賓語的動作或狀態(tài)。常用于以下動詞之后:ask, tell, advise, allow, enable, expect, force, get, like, order, teach, want, invite, wish, beg等。例如:
He asked me to do the work with him.他要我與他一起干。
You should get more people to help you.你應(yīng)該多找些人幫你。
The teacher expected everyone to study hard,老師希望每個人都努力學(xué)習(xí)。
注意:
a. 在see,watch,look at,notice, observe,have,let,make, hear,listen to,feel,help等詞后的補(bǔ)足語中,不定式不帶 to。例如:
I often hear him sing the song.我經(jīng)常聽見他唱這只歌。
The teacher usually made the students recite the text.老師通常讓學(xué)生背頌課文。
Would you please help me (to) repair my bike請幫我修理自行車好嗎
但是這些句子如果變成被動結(jié)構(gòu)時, 就必須帶 to。例如:
He is often heard to sing the song.人們常聽到他唱這只歌。
The students were usually made to recite the text.學(xué)生們常被要求背頌課文。
b. 不定式動詞在介詞 but,except,besides后面時,如果這些介詞之前有行為動詞 do的各種形式,那么,這些介詞后的不定式不帶 to,否則要帶 to.如:
She could do nothing but cry.她只是哭。
What do you like to do besides swim 除了游泳你還喜歡干什么
c.主句含有不定式,后面有rather than, rather than后省to。
d. Why not、had better、would rather、can’t but等詞后省to。如:
He could not but walk home.他只好走回家。
注意:e. 常用帶不定式作賓補(bǔ)的幾種情況:
(a) 主語 + ask / require / tell / order / force / get / want / like + sb.to do sth.
(b)主語 + think / judge / suppose / believe / consider / imagine / consider / feel + sb. + to be/ to have done
(c)主語 + call on / upon / depend on / wait for / ask for + sb.+ to do sth.
a. Father will not allow us to play on the street.
b. We believe him to be guilty.
【高考英語】不定式作表語
不定式可放在連系動詞或be動詞后面,形成表語。
例如:
My job is to help the patient.我的工作是幫助病人。
Our most important task now is to make a plan.我們現(xiàn)在最重要的任務(wù)是制定一個計劃。
注:作表語的不定式都帶to,但當(dāng)主語部分有實義動詞do時,to可以省略。
例如:
The only thing we can do now is wait and see.我們現(xiàn)在唯一能做的事就是等著看。
My work is to clean the room every day.
【高考英語】不定式作定語
不定式做定語通常要放在被修飾的詞后。例如:

We have a lot of homework to do today.今天我們有很多作業(yè)要做。
He hasn’t kept his promise to write to his parents regularly.他沒有信守定期給父母寫信的諾言。
注意:a.作定語的不定式如果是不及物動詞,或者不定式所修飾的名詞或代詞是不定式動作 的地點、工具等,不定式后面須有相應(yīng)的介詞。例如:
He is looking for a room to live in.他在找房子住。
There is nothing to worry about.沒有什么可擔(dān)心的。
Please give me a knife to cut with.請給我一把刀用。
但是,不定式所修飾的名詞是 time,place或 way,不定式后面的介詞習(xí)慣上要省去。例如:
He had no money and no place to live.他沒有錢,也沒有房子住。
b.當(dāng)作定語的不定式所修飾的名詞或代詞是不定式動作的承受者時,不定式既可以用主動語態(tài),也可用被動語態(tài),但其含義有所不同.試比較:
Have you anything to send 你有什么東西要寄嗎(不走式 to send的動作執(zhí)行者是 you)
Have you anything to be sent 你有什么要(我或別人)寄的東西嗎(不定式 to be sent的動作執(zhí)行者是已被省略的 me或 someone else)
c.下列詞語后常接不定式作定語:chance、wish、right、courage、need、promise、time、opportunity、way、the first、the second、the last、the only等。
He is always the first to come and the last to leave.他總是第一個到,最后一個走。
I have a lot of work to do.
【高考英語】省to 的動詞不定式

2) 使役動詞 let, have, make:
3) 感官動詞 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后作賓補(bǔ),省略to。
注意:在被動語態(tài)中則to 不能省掉。
The boss made them work the whole night.
=They were made to work the whole night.
4) would rather,had better:
5) Why… / why not…:
6) help 可帶to,也可不帶to, help sb (to) do sth:
7) but和except:but前是動詞do時,后面出現(xiàn)的動詞用不帶to的動詞不定式。He wants to do nothing but go out.
8) 由and, or和than連接的兩個不定式,第二個to 可以省去:
He wants to move to France and marry the girl.
9) 通常在discover, imagine, suppose, think, understand等詞后,可以省去to be:He is supposed (to be) nice.
【高考英語】動詞不定式的否定式
放在不定式符號to 前面
Tell him not to shut the window…
She pretended not to see me when I passed by.
不定式特殊句型too…to…
1)too…to太…以至于不能…
He is too excited to speak.
2) 如在too前有否定詞,則整個句子用否定詞表達(dá)肯定, too 后那個詞表達(dá)一種委婉含義,意為"不太"。
It's never too late to mend.(諺語)
3)當(dāng)too 前面有only, all, but時,意思是:非常… 等于very。
I'm only too pleased to be able to help you.
He was but too eager to get home.
不定式特殊句型so as to
1) 表示目的;它的否定式是so as not to do。

不定式的形式和主、被動
一般式 to do to be done
進(jìn)行式 to be doing
完成式 to have done to have been done
完成進(jìn)行式 to have been doing
1) 一般式:有時與謂語動詞表示的動作同時發(fā)生,有時發(fā)生在謂語動詞的動作之后。
He seems to know this.
I hope to see you again. = I hope that I'll see you again.
2) 完成式:表示的動作發(fā)生在謂語動詞表示的動作之前。
I'm sorry to have given you so much trouble.
3) 進(jìn)行式: 表示動作正在進(jìn)行,與謂語動詞表示的動作同時發(fā)生。
He seems to be eating something.
4) 完成進(jìn)行式: 表示動作或狀態(tài)從謂語動作之前一直持續(xù)到謂語動作發(fā)生。
She is known to have been thinking over the problem for many days.
【高考英語】動名詞與不定式
1) 動名詞與不定式的區(qū)別:
動名詞表達(dá)的是: 狀態(tài),性質(zhì),心境,抽象,經(jīng)常性,已發(fā)生的
不定式表達(dá)的是: 目的,結(jié)果,原因,具體,一次性,將發(fā)生的
2) 接不定式或動名詞,意義相近。
begin/ start to do = begin/ start doing; continue to do =continue doing
3) 不定式作獨(dú)立成分
例如:To tell the truth,I don’t agree with you.說實話,我不同意你的觀點。
4)不定式與疑問詞 who,which,when,where,how,what等連用,在句中起名詞作用,可充當(dāng)主語、表語、賓語等.
例如:
He didn’t know what to say. (賓語)他不知道說什么。
How to solve the problem is very important.(主語)如何解決問題是非常重要的。
My question is when to start. (表語)我的問題是何時開始。
注意:在與 why連用時,只用于 why或 why not開頭的簡短疑問句中,后面緊跟的動 詞不定式不帶 to.例如:
Why not have a rest 為什么不休息一下呢
5)不定式的復(fù)合結(jié)構(gòu) … for / of sb to do sth
以it為形式主語或形式賓語引導(dǎo)的復(fù)合結(jié)構(gòu),如果其前的形容詞是指行為的性質(zhì)就用:for sb. to do sth.。這種句式中的常用形容詞有:easy, difficult, hard, important, necessary, possible, impossible等。
如果該形容詞是指行為人的性質(zhì)和特征,則用of sb. to do sth.。這種句式中的常用形容詞有:right, wrong, brave, careful, careless, clever, wise, stupid, cruel, foolish, good, honest, kind, nice, silly等。這種復(fù)合結(jié)構(gòu)在句中可作主語、表語、賓語、定語、狀語等
It is necessary for me to learn English well.我學(xué)好英語十分必要。
It’s difficult for us to master a foreign language.我們掌握一門外語是困難的。
It’s very kind of you to come to see me.你來看我太好了。
It’s careless of the boy to make the same mistake again.那個孩子又犯了同樣的錯誤,真是太粗心了。
6)不定式在句中用主動式還是被動式, 多數(shù)情況下是容易判別的,但有時的確比較復(fù)雜, 請注意以下幾點:
a. 不定式修飾的名詞或代詞和不定式邏輯上構(gòu)成主謂關(guān)系時,不定式往往用主動形式.
Have you got a key to unlock the door(A key unlocks the door.)你有鑰匙開門嗎
b. 不定式和它前面被修飾的名詞或代詞構(gòu)成邏輯上的動賓關(guān)系,又和該句主語構(gòu)成邏輯上的主謂關(guān)系時,不定式常用主動形式.
I have got a letter to write.( I write letter.)我有一封信要寫。
He needs a room to live in.( He lives in a room.)他有一個房間住。
I know what to do.( I do what.)我知道做什么。(我自己做)
但這句如改為下列形式,不定式就得用被動形式:
I know what is to be done.我知道能做什么。(表示可能性,客觀)
這是因為 what is to be done是賓語從句,從句中的主語 what是動詞 do的動作對象。
【高考英語】不定式的時態(tài)
①不定式的一般形式所表示的動作,通常與謂語的動作(狀態(tài))同時(或幾乎同時)發(fā)生,或是在它之后發(fā)生, to do…,例如:
I saw him go out.我看見他出去了。
She wanted to be a doctor when she grew up.她長大了想當(dāng)醫(yī)生。
② 如果謂語表示的動作(情況)發(fā)生時,不定式表示的動作正在進(jìn)行,這時不定式就要用進(jìn)行式。 to be doing …
例如:
I am very glad to be working with you.我很高興與你共事。
Some students pretended to be reading English when the teacher came in.
當(dāng)老師進(jìn)來時,一些學(xué)生假裝在看書。
③ 如果不定式的動作發(fā)生在謂語動詞之前,就要用完成式。 to have done …,例如:
I’m sorry to have kept you waiting.對不起,讓你久等了。
He is said to have left the stage already as he has become an official.
據(jù)說他已經(jīng)離開舞臺了,因為他已經(jīng)當(dāng)了官員了。
【高考英語】不定式的語態(tài)
當(dāng)不定式邏輯上的主語是這個不定式所表示的動作的承受者時,不定式一般要用被動形 式。to be done / to have been done, 例如:
He asked to be sent to work in the countryside.他要求被派到農(nóng)村去工作。
It is impossible for our hopes to be realized.我們的希望不可能實現(xiàn)。
The book is said to have been translated into English. 據(jù)說這本書已經(jīng)被翻譯成英語了。
【高考英語】不定式的否定形式
不定式的否定形式由not加上不定式構(gòu)成,即:
not to do sth, not to be doing sth, not to have done sth
例如:
Mother told the children not to play football in the street.媽媽要孩子們不要在大街上踢足球。
In order not to miss the train they got up early.為了不錯過火車,他們很早就起床了。
He pretended not to have seen his friend 他假裝沒有看見他的朋友。
【高考英語】誤區(qū)提醒
1.不定式的不同形式誤用;2.被動語態(tài)中仍然省to;3.否定形式not位置弄錯;4.主動語態(tài)中該省to不省; 5.不定式作定語時丟內(nèi)容
