語(yǔ)法點(diǎn)撥
動(dòng)詞不定式
不定式由“to+動(dòng)詞原形”構(gòu)成，其否定形式是“not to do“，不定式可以帶賓語(yǔ)或狀語(yǔ)構(gòu)成不定式短語(yǔ)，沒(méi)有人稱和數(shù)的變化，但有時(shí)態(tài)和語(yǔ)態(tài)的變化。
不定式可作主語(yǔ)、賓語(yǔ)、狀語(yǔ)、表語(yǔ)和定語(yǔ)，但不能單獨(dú)作謂語(yǔ)。不定式的邏輯主語(yǔ)有時(shí)用“for+名詞或代詞賓格”構(gòu)成。
1．不定式的用法：
(1)作主語(yǔ)
不定式短語(yǔ)作主語(yǔ)時(shí)，往往放在謂語(yǔ)之后，用It作形式主語(yǔ)。例如：
To see is to believe．眼見(jiàn)為實(shí)。
It is right to give up smoking. 戒煙是對(duì)的。
(2)作賓語(yǔ)
不定式短語(yǔ)作賓語(yǔ)時(shí)，如果還帶有賓語(yǔ)補(bǔ)足語(yǔ)，往往把不定式賓語(yǔ)放在賓語(yǔ)補(bǔ)足語(yǔ)之后，而用it作形式賓語(yǔ)。例如：
He wanted to go．他想走。
I find it interesting to work with him．
我發(fā)現(xiàn)和他一起工作有趣。
(3)作賓語(yǔ)補(bǔ)足語(yǔ)。例如：
He asked me to do the work with him．
他叫我跟他一起做這個(gè)工作。
注意：在feel，hear，listen to，look at，notice，observe，see，watch，have，1et，make等詞后的補(bǔ)足語(yǔ)中，不定式不帶to。但是這些句中如果變成被動(dòng)結(jié)構(gòu)時(shí)，就必須帶to。例：
I often hear him sing the song．He is often heard to sing the song
我常聽(tīng)到他唱這首歌。他經(jīng)常被聽(tīng)到唱這首歌。
注意：不定式動(dòng)詞在介詞but，except，besides后面時(shí)，如果這些介詞之前有行為動(dòng)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。
例如：
She could do nothing but cry．她只會(huì)哭了。
What do you like to do besides swim?
除游泳外你還喜歡什么?
I have no choice but to go．我不得不走。
(4)作定語(yǔ)。例如：
I have some books for you to read.
我有幾本書(shū)供給你讀。
注①：作定語(yǔ)的不定式如果是不及物動(dòng)詞，或者不定式所修飾的名詞或代詞是不定式動(dòng)作的地點(diǎn)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 ．
他在找一個(gè)房間住。
There is nothing to worry about．
無(wú)什么可擔(dān)心的。
Please give me a knife to cut with．
請(qǐng)給我把刀子來(lái)切東西。
但是，不定式所修飾的名詞如果是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(méi)錢沒(méi)地方住。
注②：當(dāng)作定語(yǔ)的不定式所修飾的名詞或代詞是不定式動(dòng)作的承受者時(shí)，不定式既可以用主動(dòng)語(yǔ)態(tài)，也可用被動(dòng)語(yǔ)態(tài)，但其意義有所不同。試比較：
A)Have you anything to send?你有什么東西要寄嗎?(不定式tosend的動(dòng)作執(zhí)行者是you)
B)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(dòng)作執(zhí)行者是已被省略的me或someone else)
(5)作狀語(yǔ)，表示目的、原因、結(jié)果或條件。例
I came here to see you．(目的)
We were very excited to hear the news．(原因)
He hurried to the school to find nobody there . (結(jié)果)
To look at him，you would like him．(條件)
要是看見(jiàn)他，就總會(huì)喜歡他的。
目的狀語(yǔ)還可以用in order to或so as to來(lái)表示。例如：
In order to pass the exam，he worked very hard．
為了考試及格，他學(xué)習(xí)很刻苦。
We ran all the way so as not to be late．
為了別遲到我們一路上跑來(lái)的。
不定式也可以在作表語(yǔ)用的形容詞后面作狀語(yǔ)。例如：
I am very glad to hear it 聽(tīng)見(jiàn)這事我很高興。
The question is difficult to answer．這個(gè)問(wèn)題難回答。
“too+形容詞或副詞+不定式”也作狀語(yǔ)。例：
He is too old to do that．
他太老不能做這事了。
另外句子中有enough這個(gè)詞時(shí)，常用不定式作狀語(yǔ)。例如：
The room is big enough to hold us．
這間屋子夠大能盛得下我們。
(6) 作表語(yǔ)。例如：
My job is to help the patient 我的工作是幫助病人。
(7)作獨(dú)立成分。例如：
To tell the truth，I don't agree with you．
說(shuō)實(shí)話，我不同意你的觀點(diǎn)。
(8)不定式與疑問(wèn)詞who，which，when，where ,how，what等連用，在句中起名詞作用，可充當(dāng)主語(yǔ)表語(yǔ)、賓語(yǔ)等。例：
He didn't know what to say. (賓語(yǔ))
他不知道說(shuō)什么。
How to solve the problem is very important （主語(yǔ)）
如何解決這個(gè)問(wèn)題很重要。
My question is when to start．(表語(yǔ))
我的問(wèn)題是什么時(shí)候開(kāi)始。
注意：在與why連用時(shí)，只用于why或why not開(kāi)頭的簡(jiǎn)短疑問(wèn)句中，后面緊跟的動(dòng)詞不定式不帶to。例：
Why not have a rest?
(9)不定式在句中用主動(dòng)式還是被動(dòng)式，多數(shù)情況下是容易判別的，但有時(shí)的確比較復(fù)雜，請(qǐng)注意以下幾點(diǎn)：
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(shí)，不定式往往用主動(dòng)形式。
Have you got a key to unlock the door?
你有開(kāi)門的鑰匙嗎?
(A key unlocks the door．)
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(dòng)賓關(guān)系，又和該句主語(yǔ)構(gòu)成邏輯上的主謂關(guān)系時(shí)，不定式常用主動(dòng)形式。
I have got a letter to write．(I write a letter．)
我有封信要寫(xiě)。
He needs a room to live in．(He lives in a room．)
他需要間屋子住。
C)不定式作表語(yǔ)形容詞的狀語(yǔ)，和句中的主語(yǔ)構(gòu)成邏輯上的動(dòng)賓關(guān)系時(shí)，不定式多用主動(dòng)形式，這是因?yàn)槿藗兺J(rèn)為形容詞后省去了for one或for people．例如：
He is hard to talk to．很難跟他交談。
The book is difficult to understand．這本書(shū)很難懂。
但如果強(qiáng)調(diào)句中的受事者時(shí)，亦可用不定式被動(dòng)句。例如：
The handwriting is very difficult to be read．
這字太難認(rèn)讀了。
The box is to heavy to be lifted．
這箱子太重舉不起來(lái)。
D)在there be結(jié)構(gòu)中，當(dāng)說(shuō)話人考慮的是必須有人去完成某件事時(shí)，不定式用主動(dòng)形式，如果說(shuō)話人強(qiáng)調(diào)的是事情本身必須完成，則用被動(dòng)形式。
There is a lot of work to do． (Somebody has to do the work．)
There isa lot of work to be done．(The work has to be done．)
請(qǐng)注意下面兩個(gè)句子的含義是不同的：
There is nothing to do．意為無(wú)事可做，感到十分乏味。
There is nothing to be done．意為某東西壞了，無(wú)法使之恢復(fù)正常。
2．不定式的時(shí)態(tài)
(1)不定式的一般形式所表示的動(dòng)作，通常與謂語(yǔ)的動(dòng)作(狀態(tài))同時(shí)(或幾乎同時(shí))發(fā)生，或是在它之后發(fā)生。例如：
I saw him go out．我看見(jiàn)他出去了。
(2)如果謂語(yǔ)表示的動(dòng)作(情況)發(fā)生時(shí)，不定式表示的動(dòng)作正在進(jìn)行，這時(shí)不定式就要用進(jìn)行式。
例如：
I am very glad to be working with you．很高興和你一起工作。
(3)如果不定式的動(dòng)作發(fā)生在謂語(yǔ)動(dòng)詞之前，要用完成式。例如：
I'm sorry to have kept you waiting．對(duì)不起讓你久等了。
3．不定式的語(yǔ)態(tài)
當(dāng)不定式邏輯上的主語(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)形式。例如：
He asked to be sent to work in the countryside．
他要求被派往農(nóng)村工作。
