(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。如： Itbe名词to do Its our duty to take good care of the old. It takes sb+some time+to do How lon

17、g did it take you to finish the work? 不定式作宾语 以下动词后，只能跟不定式作宾语。如：agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,long, manage,offer,plan,prepare,pretend,promise,refuse,wish等，这些词大部分可接that引导的从句。如： I decided to ask for my money back. I decided that I would ask for my money back.Whe

18、n 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. 当复合宾语中的宾语是不定式时，先用形式宾语it代替不定式，把不定式置于补语之后，即：主语动 词it补语to do句式。如： We think it quite important for us to learn a foreignlanguage well. He feels it his duty

19、to help the poor. 介词but,except,besides+to do(do) 在这种句型中，如介词前有动词do，后面应接不带to的不定式；如无do，则接to不定式，即带do不带to， 带to不带do。如： The enemy soldiers had no choice but to give in. On Sunday afternoon I had nothing to do but watch TVIt is +adj.+ to do sth 句型It is difficult for us to finish writing the compositionin a

20、quarter of an hour. Itbe形容词of sbto do It is stupid of you to write down everything the teachersays. It seems(appears)形容词to do It seemed impossible to save money.在句型中，常用表示客观情况的形容词，如：difficult,easy,hard,important,impossible,necessary 等；在句型中，常用careless,clever,good,foolish,honest,kind,lazy,nice,right,si

21、lly,stupid,wise等 表示赞扬或批评的词。在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is形容词to do句式 ，如：Itskind of you to help me with my English.=You are kind to helpme with my English. 2.动词+to do（作宾语）动词不定式做宾语其实你只要把不定式(to do sth)看成一个名词即可,它属于五种基本句型里的主+谓+宾结构,例如 I beg to differ.我不敢苟同.能用此结构的动词有:决心decide determin学会learn想want希望expect

22、wish hope,拒绝refuse设法manage strive愿care假装pretend,主动ofer答应promise选choose计划plan,同意agree请求ask beg帮一帮help.为方便记忆大家把汉字连成句.另外再加上afford to do sth 承担的起3. 在一些动词之后，可以在连接代词（what/who/which)或者连接副词（how/when/where)以及whether后面接一个带to的动词不定式。这种结构是连接词宾语从句的简略形式。I wonder who to invite. (= who I should invite)Show us what t

23、o do. (=what we must do)I dont know whether to answer his letter. (=此处不用if）4.不定式作宾语时,如带有宾语补足语,则要把不定式放到后面,用it作形式宾语,构成主语+动词+it+宾补(形容词,名词)+不定式Hefounditverydifficulttogettosleep.他发现很难入睡.注意：常用此结构的动词有consider,judge,make,feel,make 等。句型四： 形容词+ to do sth of sb to do 用来说明人的性格特征和行为表现的动态形容词与不定式连用，常用brave,carefu

24、l cruel, generous,clever, foolish, kind,modest, pilite,nice,rude,stupid,等形容词 It is wise of you not to agree with you.It is generous of him to lend me his car,不定式作状语 作目的状语(1) I stayed there to see what would happen. Henry has decided to go to the hospital to be examinedby the doctor. (2)有时为了强调，不定式前可加

25、in order或so as。如： Bob took down my telephone number so as(in order)not toforget it. 有时为强调目的状语可把in order to或不定式置于句首，但so as to不能这样用。在这种句式中不定式部 分可转换为so that,in order that,成为目的状语从句，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词、过去分词或动词之后可接不定式，如：astonished,glad,ha

26、ppy,laugh ,pleased, sad,smile,sorry,surprised等。 We are glad to hear the news. I was surprised to see that a three-year-old baby could write so well. 在部分形容词后接不定式，用主动形式表示被动意义，这种句型中的主语是不定式的逻辑宾语。如：The question raised by thestudent is difficult to answer. The room is really comfortable to live in. 常这样用的形

27、容词有：comfortable,easy,dangerous,difficult,expensive,fit,impossible等。 作结果状语 We came home after our holiday to find our garden neat and tidy. 不定式作结果状语还常用在下列句式中。如： soas to;suchas to Im not so stupid(a fool) as to put it in writing.我不至于愚蠢到会把它写下来。 Im not such a stupid fool as to put it in writing. enought

28、o The speed is high enough for us to catch up with thefirst liner. only to Jane hurried back only to find her mother dying inthehospital. tooto Im too tired to stay up longer. 但在下列结构中，tooto并非是“太而不能”之意。如： Im only too glad to have passed the exam.考试及格我太高兴了。（too修饰glad to have，相当 于very） We have too much

29、 to learn.我们要学的太多了（不定式作定语）。 too.to 的用法一、too. to. 的意义 too. to 句型形式上是肯定的，但是它在意义上却是否定的，表示太而不能。too 的后面接形容词或副词的原级，to 的后面接动词原形。too. to.句型是简单句。例如：He is too young to join the army. 他年龄太小，不能参军。二、动词不定式的逻辑主语动词不定式所表示的动作的执行者与整个句子的主语不指同一人或物时，需要在动词不定式前加上一个逻辑主语(常用for sb.)。例如：The maths problem is too difficult for m

30、e to work out. 这道数学题太难我解不出来。三、too. to. 结构表达肯定的意义1. too 前面含有表示否定意义的词，如: not, never, nothing等时，too. to. 结构不表示否定的意义。例如：It is never too old to learn. 活到老，学到老。(要学永远都不迟。)2. 如果在too. to.这种结构的前面出现了only, 不仅免去了too的否定意义，反而加强了too的肯定语气，only too 相当于very 或very much。例如：I shall be only too pleased to get home. 到了家我将极

31、其高兴。3. too后接表示感情的形容词，如glad, pleased, happy, sad等时，too. to.句型不再表示否定意义，而表示的是肯定意义。例如：He is too sad to hear the bad news. 听到这个不幸的消息他太悲伤了。四、too. to. 结构与enough.to. 结构及so. that.结构的相互转换1. 将too.to.结构转换为enough. to. 结构时，要注意：(1) enough 前的形容词或副词应是too前面形容词或副词的反义词；(2) enough. to. 句式须用否定式；(3) too. to.结构有逻辑主语时，enoug

32、h. to. 结构也要加上逻辑主语。例如：She is too young to do the work. = She isnt old enough to do the work. The problem is too hard for him to work out.= The problem isnt easy enough for him to work out.2. 将too.to.结构转换为so. that. 结构时，要注意：(1) so. that. 结构是复合句，so 的后面接形容词或副词的原级，that的后面接从句。(2) that后面的从句要用否定形式。例如：She is

33、too young to go to school. = She is so young that she cant go to school.请同学们做做下列中考题，以便检验你对too. to.用法的掌握情况。变换下列句型：1. a. The box is so heavy that I cant carry it.b. The box is _ heavy_ _ _ carry. c. The box is not _ _ for me to carry.2. a. The maths problem isnt easy enough for me to work out. b. The

The book is _ interesting_ everybody likes to readit. Keys: 1. b. too, for me to c. light enough2. b. so, that c. too, for me to 3. b. s

35、o, that不定式作定语 不定式在句中作定语，置于被修饰的名词或代词之后。如： The next train to arrive is from Washington. Have you anything to be taken to your sister? Do you have anything to say on the question? Would you please give me some paper to write on? My wish to visit France has come true at last. 不定式短语作定语和被修饰词之间表示以下关系： (1)表

36、示将来的动作（例）。 (2)与被修饰词之间有动宾关系，如是不及物动词，则需加介词（例）。 (3)与被修饰词之间有动宾关系，同时与句中其它词之间又有逻辑上的主谓关系时，尽管有被动含义，却仍 用主动语态（例）；如只有动宾关系，而无逻辑上的主谓关系，则需用被动语态（例）。 (4)不定式作定语时，一般可转换为定语从句，例to arrive=that will arrive。作宾语补足语 一些及物动词除要求按宾语外，有时还需要有宾语补足语，说明宾语的行为、状态、特征，这时意思才相对完整。 (1)常要求不定式作宾补的动词有：allow,ask,advise,beg,cause,drive（强迫），enco

37、urage,expect,fo rbid,force,get,would like(love,hate),order,permit,persuade,teach,tell,want,warn,wish等。如： Would you like me to give your regards to Mary? I want you to understand the whole passage clearly.(2)部分动词后常接to be形容词、名词短语等形式，有时to be可省略，如：believe,consider,discover,find(=consider),feel(=think),i

38、magine,judge,know,prove,think,suppose,see(=understand),understa nd等。 We all believe John(to be)honest. I consider him(to be)one of the best biology teachers of No. 1 Middle School. 但当不定式是完成式时，to不能省略，如：We consider him tohave been foolish. (3)感觉动词和使役动词后用作宾补的不定式须省略to。 I didnt hear anyone say anything a

39、bout it. They make the students do too much homework every day. 这种句式在变为被动语态时，to不能省略，如第句：Thestudents are made to do too much homework every day. (4)help,know后面的to可有可无。如： Would you please help me(to) fill in the taxform? Ive never known her(to)be late before.但：He was known to have been to France befor

40、e. (5)部分短语动词后，常接不定式作宾补，如： You may depend on them to be there early. The Party calls on us to increase production and practise economy. 常这样用的短语动词有：ask for,care for,call on,count on,depend on,wait for,long for（渴望）， prepare for,wish for等。作主语补足语 不定式作主语补足语，和主语构成一种逻辑上的主谓关系。如： He was not allowed to enter t

41、he classroom for being late. The young university student is considered to have great promise. 不定式短语还可作独立成分，用于句首、句中或句末。如： To tell the truth,the play was a great disappointment tome. 常见的短语有to be exact（确切地说），to begin with（首先），to do him justice（说句对他公道的 话），to be sure（真的）等等。不定式作表语表示具体动作或将来动作；To be kind t

42、o the enemy is to be cruel to the people. My chief purpose is to point out the difficulties ofthe matter. What I would suggest is to put off the meeting. 动名词作主语 Learning without practice is no good. 动名词作主语时，也常用It句式。如： Its +no good(no use,fun,a pleasure,a waste of time)+doing Its no good reading in d

43、im light. Its no use sitting here waiting. Its形容词doing Its dangerous swimming in the sea in windy days. 这样用的形容词有expensive,nice,tiring等，但important,necessary则不适用于这种结构，应用不定式 代替，如：Itsimportant for you to keep fit. There is no+doing There is no saying what will happen next. 在这一结构中，动名词后常带宾语，相当于Its impossi

44、ble to结构。 动词不定式和动名词作主语的区别 不定式作主语经常表示具体动作，常与特定的动作执行者联系在一起；而动名词作主语经常表示抽象动作，经常不与特定的动作执行者联系在一起。如： Its no good eating too much fat. Its no good for you to eat so much fat. 动名词结构作主语，可以用名词或代词属格形式作逻辑主语。如： Its no use your pretending that you didnt know the rules.二、作宾语 动名词作宾语 以下动词后，只能接动名词作宾语，如：admit,appreciat

45、e,consider,delay,enjoy,finish,keep,imag ine,mind,miss,practise,resist,risk,save,suggest,dont mind,give up,insist,on, put off等。如： I suggest spending our summer vacation in a seaside town.
