難點(diǎn)
1. Imagination is more important than knowledge．

他的工作比過去做得更好。

但是，該句型有時(shí)卻不表示否定，而表示肯定，有以下三種情況：
(1)如果too后為glad，pleased，happy，eager，anxious，willing，ready(甘心的、情愿的)，easy 等表示心情(情緒)的形容詞時(shí)，該句型表示肯定意義，這時(shí)too相當(dāng)于very。

Grammar
一 不定式的用法
不定式由“to+動(dòng)詞原形”構(gòu)成其否定形式是"not to do”。
不定式可以帶賓語或狀語構(gòu)成不定式短語，
沒有人稱和數(shù)的變化，但有時(shí)態(tài)和語態(tài)的變化。
to do 一般式
不定式的主動(dòng)式有 to have done 完成式
to be doing 進(jìn)行式
被動(dòng)式最常用的是 to be done。
不定式的用法主要有：主語、賓語、表語、定語、賓語補(bǔ)足語、狀語,但不能作謂語。
1.作主語：不定式短語作主語時(shí)，往往放在謂語之后，用it作形式主語。 例：To see is to believe．
It is right to give up smoking．
It is a great pleasure to talk with him.
It is important for us to learn English well.
It is kind of you to help me so much.
注意：
要想說明不定式的動(dòng)作是由誰發(fā)出，可在不定式前加for sb.；但如果是形容詞
careless, clever, foolish, good, impolite, kind, nice, silly, stupid 等作表語時(shí)用of sb.
2.作賓語：不定式短語作賓語時(shí)，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。
eg：e wanted to go．
I find it interesting to work with him．
Most of them don't know how to solve the problem.
You can decide whether to stay at home or play football.
注意：
有些動(dòng)詞后如：know, decide, find out, show, learn, teach, tell, wonder 常用 動(dòng)詞+疑問詞+不定式 的形式。
3.作定語: 一般放在被修飾的名詞或代詞之后。
eg：I have some books for you to read．
注意：
(1)作定語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。
eg：He is looking for a room to live in．
There is nothing to worry about．
Please give me a knife to cut with．
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。
eg：He had no money and no place to live．
(2)當(dāng)作定語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)語態(tài)，也可用被動(dòng)語態(tài)，但其含義有所不同。試比較：
(1)Have you anything to send? 你有什么東西要寄嗎?
(不定式to send的動(dòng)作執(zhí)行者是you)
②Have 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)
4.作狀語: 表示目的、原因、結(jié)果或條件
eg：I came here to see you．(目的)
We were very excited to hear the news．(原因)
He hurried to the school only to find nobody there．(only to…常表示未曾料到的結(jié)果)
To look at him，you would like him．(條件)
注意：
目的狀語還可以用in order to或so as to來表示。
eg：In order to pass the exam, he worked very hard.
We ran all the way so as not to be late．
(2)不定式也可在作表語用的形容詞后面作狀語。
eg：I am very glad to hear it．
he question is difficult to answer．
(3)“too+形容詞或副詞+不定式”也作狀語。
eg：He is too old to do that．
另外句子中有enough這個(gè)詞時(shí)，常用不定式作狀語。
eg： The room is big enough to hold us．
5.作賓語補(bǔ)足語
eg：He asked me to do the work with him．
(1)在feel，hear，listen to，look at，notice，observe，see，watch，have，let，
make等詞后的補(bǔ)足語中，不定式不帶to，但是這些句子如果變成被動(dòng)結(jié)構(gòu)時(shí)，就必須帶to。
eg: I often hear him sing the song．
He is often heard to sing the song．
(2)動(dòng)詞不定式在介詞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。
eg：She could do nothing but cry．
What do you like to do besides swim?
I have no choice but to go．
6.作表語
eg：My job is to help the patient．
7.作獨(dú)立成分
eg： To tell the truth，I don't agree with you．
8.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。
eg：He didn't know what to say．(賓語)
How to solve the problem is very important．(主語)
My question is when to start．(表語)
二 不定式的省略
在一定的語境中，為了避免重復(fù)，在某些詞語的后面不定式可省略，但不定式to通常不能省略。
1. 形容詞后不定式的省略。這類形容詞有：happy，gIad，ready，eager，anxious等。
如：I’ ll be away on a business trip．Would you mind looking after my cat?
Not at all。I’ d be happy to．
2. 賓語補(bǔ)足語、主語補(bǔ)足語中不定式的省略。這類動(dòng)詞有l(wèi)agk，teIl，order，persuade，advise，wish，permit，allow等。
如：The boy wanted to ride his bicycle in the street, but his mother told him not to．

2. When I handed the report to John，he said that George was the person______．(上海高考題)
A．to send B．for sending
C．to send it to D．for sending it to
[解析] 賓語從句還原則完成了send the report(it)to the person。當(dāng)它變成不定式作定語則成了the person to send it(the report)to。 for 引導(dǎo)的短語不可作定語。[答案] C

A．to wash B．washing C．wash D．to be washing
[解析] 不定式在使役動(dòng)詞 make 后作賓語補(bǔ)足語時(shí)不帶to，但如果make變?yōu)楸粍?dòng)語態(tài),不定式就成了主語補(bǔ)足語，就須加上to。 [答案】 A

A．sit B．sit on
C．be sat D．be sat on (全國高考題)

一-- 0h，I forgot_______．
A．turning it off B．turn it off

A．to be taken B．to take
C．being taken D. taking (全國高考題)

12. He gave me this strange object for my birthday and I don't know_______.
A．it what to do with B．what to do it with
C．what to do with it D．to do what with it
[解析] 該題考查名詞詞組作用的“疑問詞+不定式”的用法。根據(jù)句意和結(jié)構(gòu)，空白處應(yīng)填“疑問詞+不定式”結(jié)構(gòu)，作know的賓語。do with 在此意為“利用”、“使用”。[答案] c

has a role_______ in making the earth a better place to live．
A．to have played B．to play
C．to be played D．to be playing(2003年上海春招題)
[解析] 本題考查動(dòng)詞不定式作后置定語的用法。這里是不定式作定語，修飾a role。但要注意不定式的不同形式表達(dá)不同含義。to have played表示完成；to be playing表示進(jìn)行;play表示將來；to be played表被動(dòng)關(guān)系。根據(jù)句意“她會(huì)告訴我們?yōu)槭裁此@樣強(qiáng)烈地感覺到：在使地球成為更美好的居住地中，我們每個(gè)人起到一定作用�！笔潜硎緦�。
再者要注意當(dāng)動(dòng)詞不定式與所修飾的名詞之間為動(dòng)賓關(guān)系，同時(shí)與句子主語為主謂關(guān)系時(shí)，動(dòng)詞不定式用其主動(dòng)形式表示被動(dòng)意思，故排除c項(xiàng)。由題干從句中時(shí)態(tài)來看，為一般現(xiàn)在時(shí)(has arole)，故此處表示“起作用”，并非已完成的動(dòng)作或正在起作用，故排除A、D兩項(xiàng)。[答案] B
