来代替不定式结构,这时it被称为形式主语,而作为句子真正主语的不定式则被后置.往往放v.和adj.之后.e.g.TolearnEnglishwellisnoteasy.=It’snoteasytolearnEnglishwell.It’s+adj.(+forsb.)+todosth.1.不定式做主语（主体是什么事什么人）：常用句型：It’s+adj.(+forsb.)+todosth.

（对某人来说）做某事是怎样的形式主语真正主语=Toworkouttheproblemisdifficultforme.It’sdifficultformetoworkouttheproblem.=Workingouttheproblemisdifficultforme.e.g.对我来说解答出这道题是很难的。2.ThebestwaytolearnEnglishistoreadloudly.(做表语)可与be动词构成系表结构.HerwishistostudyinJiYanMiddleschool.Myjobistocleanthestreets.在形式上，位于系动词后的就是表语。从含义上讲，表语是回答主语“是什么”的语法成分。2.不定式做表语：常放在be动词后，表明主语“是什么”。e.g.Ourplanistogotherebyplane.

我们的计划是乘飞机去那儿。（主语和表语指代的是同一事物）1.Myjobis_________computers.tosellingB.sellC.tosell2.Herhobbyis______(play)football.toplay=Herhobbyisplayingfootball.3.Iwanttobuyaticket.(做宾语)接动词不定式作宾语常见的几个动词是want,plan,hope,decide,begin,start.need,wait,wouldlike.hate.refuse.wish.prefer,learn.try.like.agree,fail.beabletodo,do/tryone’sbesttodo等.e.g.Theydecidedtotryagain.Thelittleboywantedtogettoschoolbefore8o’clock.3.不定式做宾语：即动词+todo的结构中这里的todo就是做宾语(表示动作、行为的对象)1.Myfriendswant________(book)someticketstothemovieforus.2.Myparentsdecide_____(give)memoremoney.3.Heplans_____(go)toBeijingforaholiday.4.Theboyhopes______(pass)theEnglishexam.5.Mylittlesonisable_____(read)somewords.6.I’lltrymybest_____(help)you.7.Shewouldlike_____(become)beautiful.4.KangkanghelpedustolearnEnglish.（1）动词不定式作宾语补足语,常见的动词有tell,ask,get,want,wouldlike,wish,teach,help,order

,invite,get,allow,send,lead等.常构成下面的句式：V+sb.+todo其否定形式为：V+sb.not+todo(做宾语补足语)Shetoldmenottogivethebooktohim.

IaskedPaultocarrythebox.4.不定式做宾语补足语：即动词+sb.+todo的结构中这里的todo就是做宾语补足语（补充说明宾语，至于宾语之后）1.Don’taskJim___(go)swimmingwithus,becausehismotherwon’tallowhim____(do)so.2.Doesyoumotherwishyou____adoctor?A.beingB.tobeC.become3.Myteacheralwaystellsme____(study)hard.4.Idon’twantyou____(help)me.5.She’dlikeme____(join)them.6.Iwishyou____(have)agoodtime.Mybestfriendsteachme____(swim).8.Herfriendofteninvitesher____(have)dinner.9.Mymotheralwaysgetsmyfather____(do)housework.10.Iorderyou____(wash)yourhands二看

todotoliveintotalkwith

不定式做定语：用来修饰前面的名词或者不定代词。注意：

他在找一个房间住。没什么可担心的。

请给我把笔来写东西。Heislookingforaroomtolivein

．Thereisnothingtoworryabout．Pleasegivemeapentowritewith．不定式和宾语之间有时候必须加上相应的介词，才能构成完整的动宾关系。5.Igetupearlytocatchthebus.(做目的状语)不定式作状语一般表示目的，原因或结果．Iamsorrytohearthat.Let’sstoptohavearest.Theorangearetoohightoreach.Shedidn’tworkhardenoughtopasstheexam.(表原因)(表目的)不定式做状语：常用来表示目的，原因或结果。(表结果)(表结果)Shesellsflowers___makemoney.A.madeB.makeC.tomake2.Theroomisnotbigenough____.A.toliveinB.forlivingC.tolive3.I’msorry______you.A.hitB.tohitC.hitting4.Heistooyoung___(go)toschool.7.疑问词+todo构成短语。Wedon’tknowwhentoleaveBeijing.Canyoushowmehowtoswim.Hedidn’ttellmewhentoleave.1.JoeisteachingAlice______thechair.howmendB.howmendingC.howtomend2.Idon’tknowwhat____(do)next.3.Couldyoutellmewhen____(have)dinner?8.在学习不定式中,我们需要注意些什么呢?1）记住基本形式:todo否定:nottodo2）todo是非谓语动词,没有人称和数的变化,不能充当谓语.但可以和系动词构成系表结构.如:Mydreamistobeadoctor.3）感官动词see,watch,hear,feel等和使役动词make,let等接do作宾语补足语时,do称为不带to的不定式如:Doyouoftenseehimplaytennisontheplayground?4）充当后置定语时,要特别注意动词的不定式短语中的介词不能省去.如:Theoldmanhavenohousetolivein.8.只能跟ving的动词：finish,enjoy,mind,keep(on),practise,feellike(want),bebusydoing,giveup,lookforwardtodoing,can’thelpdoing,can’tstanddoing1.Ican’thelp_____(cry).2.Hedidn’tfinish____(do)homework.3.Wouldyoumind____(close)thewindow.4.EverydayMarypractise______(speak)English.5.Kangkangisbusy_____(watch)TVnow.6.Ilookforwardto___(hear)fromyou.7.Theykeep____(play)basketball.8.Mysisterfeelslike______(eat)icecream.9.既可以跟动词不定式又可以跟Ving的几组动词而意思无太大区别的：liketodolikedoingprefer.hatebeginstart…….10.注意stoptodo与stopdoing：stoptodo指的是：停下其它的事情，去做不定式的动作。
