FunctionsofInfinitive

1主语(subject)2表语(predicative)3宾语(object)4宾补(objectcomplement)5定语(attribute)6状语(adverbial)

7独立结构(absoluteconstruction)

1不定式作主语(subject)Tokeepsmiling

ishealthyforyou.It’simportanttolookupthenewwordsinthedictionary

whenyoustudyEnglish.单个不定式作主语时,谓语动词用单数。若不定式太长,往往用it作形式主语,不定式后置。Myjobtoprotecttheworld.Myambitionisto_____________.is2不定式作表语(predicative)

Seeingistobelieve.Toseeisbelieving.Seeingisbelieving.Toseeistobelieve.×√√×不定式常用在系动词be,seem,appear,get,remain等后作表语。Allyouhavetodois(to)finishthejobquickly.如果主语部分有个表示不定式内容的do,用作表语的不定式可省略to。YaoMinglikestoplay

basketball.Ifinditstillnecessary(forhim)to_________ifhewantstowin.

3不定式作宾语(object)句型：think/consider/findit+adj.+todo常接动词不定式作宾语的动词有：agree,afford,appear,ask,attempt,care,choose,claim,dare,decide,demand,deserve,determine,expect,fail,get,hate,hesitate,hope,hurry,intend,learn,manage,offer,plan,prepare,pretend,promise,refuse,seem,tend,threaten,want,wish。2)feel,find,judge,make,think,believe,consider

等动词后如果是不定式做宾语，补语是形容词(间或是名词)，常用it作形式宾语，把不定式后移。

Ifinditdifficulttoworkwithhim.疑问词who,which,when,how,what等与不定式连用，在句中起名词作用，可充当主语、表语、宾语等。Hedidn’tknowwhattosay.(宾语)他不知道说什么。Howtosolvetheproblemisveryimportant.(主语)如何解决这个问题很重要。Myquestioniswhentostart.(表语)我的问题是什么时候开始。

疑问词+不定式4不定式作宾补(objectcomplement)Mymumasksmetoplaythepiano

twohourseveryday.Theteachertoldmetocleantheblackboard.Iexpectyoutogivemesomehelp.引导不定式作宾补的动词：warn,tell,allow,help,ask,force等+sbtodosth

lookat

observe

notice三使

let

make

have

二听一感觉:

feel+sbdosth（不带to）1.Theysawtheboyfallsuddenlyfromthetree.Theboywasseentofallsuddenlyfromthetree.但当以上的动词用于被动式，to要还原：

MothermadeJohnwashthecarforaweek.

Johnwasmadetowashthecarforaweek.3不定式用在介词but,except,besides后时,如果这些介词前有行为动词do的各种形式,那么介词后的不定式不带to,相反则带to。1.Shecoulddonothingbutcry.2.Ihavenochoicebuttogo.3.Whatdoyouliketodo

besidessleep.5不定式作定语(attribute)1.Kateislookingforasuitablecoattowear.2.Tomhasanicepentowritewith.1.不定式作定语与所修饰的词之间有三种关系：Ihavealotofworktodo.我有很多工作要做。Heisalwaysthefirsttocome.他总是第一个来。Weallhaveachancetogotocollege.我们都有上大学的机会。(1)动宾关系(2)主谓关系(3)同位关系2.当名词被thefirst,thelast,theonly等词以及形容词最高级修饰时eg:

Sheisalwaysthefirsttocomeandthelasttoleave.3.something,anything,nothing,everything等复合不定代词常用不定式做后置定语。注意比较：1)Haveyouanythingtosend?

你有什么东西要寄吗？2)Haveyouanythingtobesent?

你有什么要（我或别人）寄的东西吗？

（不定式tosend的动作执行者是you）（不定式tobesent的动作执行者是已被省略的me或someoneelse）5.如果不定式是不及物动词,则后面需适当的介词。

Pleasepassmesomepapertowrite____.on4.也可用在have…todo和therebe

句型中。

Thereisnoonetotakecareofher.Ihavenojewelrytowear.Igotupearlyto_____________.

Youcamehereto________.inorderto,soasto,enoughto,onlyto,too...tocatchthetrain

6不定式作状语(adverbial)在一些短语中也有体现eg:Hespokeloudly(soas/inorder)tobeheard.1.

表示目的:toinordertosoastoso/such…astodo不定式作状语2.

表示原因:

不定式可以用在作表语的形容词后作状语,sorry,surprised,happy,glad,eager,angry,foolish,right,wrong,slow,quick,rude,cruel,disappointed等。eg:I’mglad/pleasedtoseeyou.Weweresurprisedtohearthenews.so+adj./adv.+astodo…such+adj.+n.+astodo…adj./adv.+enough+todotoo+adv./adj.+todo

Hewassofoolishastobelieveit.=Hewassuchafoolastobelieveit.=Hewasfoolishenoughtobelieveit.3.结果状语:常与only,enough或too连用Hestudiedhardonlytofailtheexam.Totellthetruth,Iamnothappyatthemoment.tobefranktobehonesttotellthetruth7

独立结构(absoluteconstruction)

8.不定式的否定结构：不定式的否定结构多由“not+不定式”构成，否定副词not,never,seldom,hardly等要置于to前。请告诉你的小孩不要在街上玩耍。Pleasetellyourchildnottoplayinthestreet.她检查名字为了不犯错误。Shecheckedthenamesso
