(2)用it作形式主語(yǔ)，把真正的主語(yǔ)不定式置于句后，常用于下列句式中。如：

17、Itbe名詞to do It's our duty to take good care of the old. It takes sb+some time+to do How long did it take you to finish the work? 不定式作賓語(yǔ) 以下動(dòng)詞后，只能跟不定式作賓語(yǔ)。如：agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,long, manage,offer,plan,prepare,pretend,promise,refuse,wish等，這些詞大部分可接th

18、at引導(dǎo)的從句。如： I decided to ask for my money back. I decided that I would ask for my money back.When our visit to the farm was over,we expected to startback on foot. When our visit to the farm was over, we expected that wewould start back on foot. 當(dāng)復(fù)合賓語(yǔ)中的賓語(yǔ)是不定式時(shí)，先用形式賓語(yǔ)it代替不定式，把不定式置于補(bǔ)語(yǔ)之后，即：主語(yǔ)動(dòng) 詞it補(bǔ)語(yǔ)to do

19、句式。如： We think it quite important for us to learn a foreignlanguage well. He feels it his duty to help the poor. 介詞but,except,besides+to do(do) 在這種句型中，如介詞前有動(dòng)詞do，后面應(yīng)接不帶to的不定式；如無(wú)do，則接to不定式，即帶do不帶to， 帶to不帶do。如： The enemy soldiers had no choice but to give in. On Sunday afternoon I had nothing to do but

20、 watch TVIt is +adj.+ to do sth 句型It is difficult for us to finish writing the compositionin a quarter of an hour. Itbe形容詞of sbto do It is stupid of you to write down everything the teachersays. It seems(appears)形容詞to do It seemed impossible to save money.在句型中，常用表示客觀情況的形容詞，如：difficult,easy,hard,impo

21、rtant,impossible,necessary 等；在句型中，常用careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise等 表示贊揚(yáng)或批評(píng)的詞。在不定式前的sb，可看作其邏輯主語(yǔ)。這一句式有時(shí)相當(dāng)于Sb is形容詞to do句式 ，如：It'skind of you to help me with my English.=You are kind to helpme with my English. 2.動(dòng)詞+to do（作賓語(yǔ)）動(dòng)詞不定式做賓語(yǔ)其實(shí)你只要把不定式(to do sth)看

22、成一個(gè)名詞即可,它屬于五種基本句型里的主+謂+賓結(jié)構(gòu),例如 I beg to differ.我不敢茍同.能用此結(jié)構(gòu)的動(dòng)詞有:決心decide determin學(xué)會(huì)learn想want希望expect wish hope,拒絕refuse設(shè)法manage strive愿care假裝pretend,主動(dòng)ofer答應(yīng)promise選choose計(jì)劃plan,同意agree請(qǐng)求ask beg幫一幫help.為方便記憶大家把漢字連成句.另外再加上afford to do sth 承擔(dān)的起   3. 在一些動(dòng)詞之后，可以在連接代詞（what/who/which)或者連接副詞（

23、how/when/where)以及whether后面接一個(gè)帶to的動(dòng)詞不定式。這種結(jié)構(gòu)是連接詞賓語(yǔ)從句的簡(jiǎn)略形式。I wonder who to invite. (= who I should invite)Show us what to do. (=what we must do)I dont know whether to answer his letter. (=此處不用if）4.不定式作賓語(yǔ)時(shí),如帶有賓語(yǔ)補(bǔ)足語(yǔ),則要把不定式放到后面,用it作形式賓語(yǔ),構(gòu)成"主語(yǔ)+動(dòng)詞+it+賓補(bǔ)(形容詞,名詞)+不定式"He found it very

24、 difficult to get to sleep. 他發(fā)現(xiàn)很難入睡.注意：常用此結(jié)構(gòu)的動(dòng)詞有consider,judge,make,feel,make 等。句型四： 形容詞+ to do sth of sb to do 用來(lái)說(shuō)明人的性格特征和行為表現(xiàn)的動(dòng)態(tài)形容詞與不定式連用，常用brave,careful cruel, generous,clever, foolish, kind,modest, pilite,nice,rude,stupid,等形容詞 It is wise of you not to agree with you

25、.It is generous of him to lend me his car,不定式作狀語(yǔ) 作目的狀語(yǔ)(1) I stayed there to see what would happen. Henry has decided to go to the hospital to be examinedby the doctor. (2)有時(shí)為了強(qiáng)調(diào)，不定式前可加in order或so as。如： Bob took down my telephone number so as(in order)not toforget it. 有時(shí)為強(qiáng)調(diào)目的狀語(yǔ)可把in order to或不定式置于句首，但

26、so as to不能這樣用。在這種句式中不定式部 分可轉(zhuǎn)換為so that,in order that,成為目的狀語(yǔ)從句，如： I stayed there so that (in order that)I could see whatwould happen. (3)在部分表示感情色彩的形容詞、過(guò)去分詞或動(dòng)詞之后可接不定式，如：astonished,glad,happy,laugh ,pleased, sad,smile,sorry,surprised等。 We are glad to hear the news. I was surprised to see that a three-ye

27、ar-old baby could write so well. 在部分形容詞后接不定式，用主動(dòng)形式表示被動(dòng)意義，這種句型中的主語(yǔ)是不定式的邏輯賓語(yǔ)。如：The question raised by thestudent is difficult to answer. The room is really comfortable to live in. 常這樣用的形容詞有：comfortable,easy,dangerous,difficult,expensive,fit,impossible等。 作結(jié)果狀語(yǔ) We came home after our holiday to find our

28、 garden neat and tidy. 不定式作結(jié)果狀語(yǔ)還常用在下列句式中。如： soas to;suchas to I'm not so stupid(a fool) as to put it in writing.我不至于愚蠢到會(huì)把它寫(xiě)下來(lái)。 I'm not such a stupid fool as to put it in writing. enoughto The speed is high enough for us to catch up with thefirst liner. only to Jane hurried back only to find

29、her mother dying inthehospital. tooto I'm too tired to stay up longer. 但在下列結(jié)構(gòu)中，tooto并非是“太而不能”之意。如： I'm only too glad to have passed the exam.考試及格我太高興了。（too修飾glad to have，相當(dāng) 于very） We have too much to learn.我們要學(xué)的太多了（不定式作定語(yǔ)）。 too.to 的用法一、too. to. 的意義 too. to 句型形式上是肯定的，但是它在意義上卻是否定的，表示"太而不能

30、"。too 的后面接形容詞或副詞的原級(jí)，to 的后面接動(dòng)詞原形。too. to.句型是簡(jiǎn)單句。例如：He is too young to join the army. 他年齡太小，不能參軍。二、動(dòng)詞不定式的邏輯主語(yǔ)動(dòng)詞不定式所表示的動(dòng)作的執(zhí)行者與整個(gè)句子的主語(yǔ)不指同一人或物時(shí)，需要在動(dòng)詞不定式前加上一個(gè)邏輯主語(yǔ)(常用for sb.)。例如：The maths problem is too difficult for me to work out. 這道數(shù)學(xué)題太難我解不出來(lái)。三、too. to. 結(jié)構(gòu)表達(dá)肯定的意義1. too 前面含有表示否定意義的詞，如: not, never, n

31、othing等時(shí)，too. to. 結(jié)構(gòu)不表示否定的意義。例如：It is never too old to learn. 活到老，學(xué)到老。(要學(xué)永遠(yuǎn)都不遲。)2. 如果在too. to.這種結(jié)構(gòu)的前面出現(xiàn)了only, 不僅免去了too的否定意義，反而加強(qiáng)了too的肯定語(yǔ)氣，only too 相當(dāng)于very 或very much。例如：I shall be only too pleased to get home. 到了家我將極其高興。3. too后接表示感情的形容詞，如glad, pleased, happy, sad等時(shí)，too. to.句型不再表示否定意義，而表示的是肯定意義。例如：He

32、 is too sad to hear the bad news. 聽(tīng)到這個(gè)不幸的消息他太悲傷了。四、too. to. 結(jié)構(gòu)與enough.to. 結(jié)構(gòu)及so. that.結(jié)構(gòu)的相互轉(zhuǎn)換1. 將too.to.結(jié)構(gòu)轉(zhuǎn)換為enough. to. 結(jié)構(gòu)時(shí)，要注意：(1) enough 前的形容詞或副詞應(yīng)是too前面形容詞或副詞的反義詞；(2) enough. to. 句式須用否定式；(3) too. to.結(jié)構(gòu)有邏輯主語(yǔ)時(shí)，enough. to. 結(jié)構(gòu)也要加上邏輯主語(yǔ)。例如：She is too young to do the work. = She isn't old enough to

33、do the work. The problem is too hard for him to work out.= The problem isn't easy enough for him to work out.2. 將too.to.結(jié)構(gòu)轉(zhuǎn)換為so. that. 結(jié)構(gòu)時(shí)，要注意：(1) so. that. 結(jié)構(gòu)是復(fù)合句，so 的后面接形容詞或副詞的原級(jí)，that的后面接從句。(2) that后面的從句要用否定形式。例如：She is too young to go to school. = She is so young that she can't go to scho

34、ol.請(qǐng)同學(xué)們做做下列中考題，以便檢驗(yàn)?zāi)銓?duì)too. to.用法的掌握情況。變換下列句型：1. a. The box is so heavy that I can't carry it.b. The box is _ heavy_ _ _ carry. c. The box is not _ _ for me to carry.2. a.

My wish to visit France has come true at last. 不定式短語(yǔ)作定語(yǔ)和被修飾詞之間表示以下關(guān)系： (1)表示將來(lái)的動(dòng)作（例）。 (2)與被修飾詞之間有動(dòng)賓關(guān)系，如是不及物動(dòng)詞，則需加介詞（例）。 (3)與被修飾詞之

37、間有動(dòng)賓關(guān)系，同時(shí)與句中其它詞之間又有邏輯上的主謂關(guān)系時(shí)，盡管有被動(dòng)含義，卻仍 用主動(dòng)語(yǔ)態(tài)（例）；如只有動(dòng)賓關(guān)系，而無(wú)邏輯上的主謂關(guān)系，則需用被動(dòng)語(yǔ)態(tài)（例）。 (4)不定式作定語(yǔ)時(shí)，一般可轉(zhuǎn)換為定語(yǔ)從句，例to arrive=that will arrive。作賓語(yǔ)補(bǔ)足語(yǔ) 一些及物動(dòng)詞除要求按賓語(yǔ)外，有時(shí)還需要有賓語(yǔ)補(bǔ)足語(yǔ)，說(shuō)明賓語(yǔ)的行為、狀態(tài)、特征，這時(shí)意思才相對(duì)完整。 (1)常要求不定式作賓補(bǔ)的動(dòng)詞有：allow,ask,advise,beg,cause,drive（強(qiáng)迫），encourage,expect,fo rbid,force,get,would like(love,hate),o
