findsb.tobe likesb.todo

wouldlikesb.todohelpsb.todoImadehimdohiswork.Hewasmadetodohiswork(byme).不定式用在介詞but,except,besides后時(shí),如果這些介詞前有行為動詞do的各種形式,那么介詞后的不定式不帶to,相反則帶to.(1).Shecoulddonothingbutcry.(2).Ihavenochoicebuttogo.(3).Whatdoyouliketodo

besidessleep.Ihavesomethingtosay.Hehasalotofhomeworktodo.Heislookingforaroomtolivein.Thereisnothingtoworryabout.(5).定語(如果不定式中的動詞是不及物動詞,則不定式中要有介詞.)不定式作定語時(shí)，應(yīng)放在被修飾詞的后面，而且放在其他后置定語之后。1.不定式做定語與所修飾的詞之間有三種關(guān)系：(1)動賓關(guān)系

Ihavealotofworktodo.我有很多工作要做。(2)主謂關(guān)系

Heisalwaysthefirsttocome.他總是第一個(gè)來。(3)同位關(guān)系

Weallhaveachancetogotocollege.我們都有上大學(xué)的機(jī)會。2.不定式所修飾的名詞或代詞是不定式動作的地點(diǎn)工具等，即使是及物動詞，不定式后面仍須有相應(yīng)的介詞。

3.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。Hehadnomoneyandnoplacetolive.他沒錢沒地方住。請給我一支寫字的筆.Pleasegivemeapentowritewith.4.something,anything,nothing,everything等復(fù)合不定代詞常用不定式做后置定語。注意比較：Doyouhaveanythingtosend?你有什么東西要寄嗎？（不定式tosend的動作執(zhí)行者是you）2.Doyouhaveanythingtobesent?你有什么要（我或別人）寄的東西嗎？（不定式tobesent的動作執(zhí)行者是已被省略的me或someoneelse）Icameheretoseeyou.Hegotupearlytocatchthetrain.(6)狀語inorderto,soasto,enoughto,onlyto,too….to.,(7).獨(dú)立結(jié)構(gòu)tobefrank,tobehonest,totellthetruthTotellthetruth,Idon’tagreewithyou.關(guān)于小品詞to(1).不定式中的動詞上文已出現(xiàn)過,下文要省略該動詞.eg:Wouldyouliketogowithme?I’dliketo.(2).不定式是tobe結(jié)構(gòu),be不可省.eg:Wouldyouliketobeateacher?I’dliketobe.不定式與疑問詞who,which,when,how,what等連用，在句中起名詞作用，可充當(dāng)主語、表語、賓語等。Hedidn’tknowwhattosay.他不知道說什么。(賓語)Howtosolvetheproblemisveryimportant.如何解決這個(gè)問題很重要。(主語)Myquestioniswhentostart.我的問題是什么時(shí)候開始。(表語)注意：在與why連用時(shí)，只用于why或whynot開頭的簡短疑問句中，后面緊跟的動詞不定式不帶to。

Whynothavearest?固定句型:hadbetter/hadbest+(not)dosth.最好（不）做某事Why(not)dosth.?…prefertodo/preferdoing…prefer+n./doingA+to+n./doingB…prefer+todoAratherthan(to)doB…wouldrather(not)dosth.…wouldratherdoAthan(do)B…wouldrather+句子（過去式）（虛擬語氣）要做……(1).Theypretendednottoseeus.(2).Hepretendedtobesleeping.(3).Shepretendedtohaveknownitbefore.(一般式表示與謂語的動作同時(shí)/幾乎/發(fā)生在它之后.)(在謂語動詞發(fā)生的同時(shí),不定式的動作也正在進(jìn)行)(完成式表示動作發(fā)生在謂語動作之前)(4).We’rehappytohavebeenworkingwith

you.(完成進(jìn)行式表示謂語動作發(fā)生之前,不定式的動作一直在進(jìn)行而且可能之后也繼續(xù))Myteacherwasmade_____histeachingbecauseofpoorhealth.givingupB.togiveupC.giveupD.givenup2.Thesentencewants____oncemore.explainedB.toexplainC.beingexplainedD.explaining3.TheArcticisconsidered____thenorthernpartoftheAtlantic.havingbeenB.tohavebeenC.tobeD.beingBDC4.TheEmperororderedthewonderfulcloth_____forhimwithoutdelay.tohavewovenB.tobewovenC.tobeweavingD.toweave5.IfoundtheGermanlanguagehard____.learnedB.learningC.tobelearnedD.tolearn6.—Thelightintheofficeisstillon.Oh,Iforgot______.turningitoffB.turnitoffC.toturnitoffD.havingturneditoffBDC7.Howdoyoudealwiththedisagreementbetweenthecompanyandthecustomers?Thekey____theproblemistomeetthedemand____bythecustomers.tosolving,makingB.tosolving,madeC.tosolve,makingD.tosolve,made8.Whatdoyouthinkoftheschool?Itisaverygood_____.schooltostudyinB.schoolforchildrentostudyC.studyingschoolD.schooltostudyBA9.Didyougetajob?No,I___,butit’snouse.expectedB.triedtoC.managedtoD.planned10.Wefinditimpossibleforthework___aheadoftime.tofinishB.finishingC.beingfinishedD.tobefinished11.IusuallygotoShanghaibytrain.Whynot___therebyboatforachange?totrytogoB.trygoingC.totrygoingD.trytogoBDB12.___aliving,shehadtoworkfrommorningtillnight.TomakeB.MadeC.MakingD.Tohavemade13.Iwouldratherstarvetodeaththan___forfood.begB.beggingC.beggedD.tobeg14.Theboypretended____whenhismotherentered.readingB.toreadC.tobereadingD.beingreadAACExercise1.Robertissaid____abroad,butIdon’tknowwhatcountryhestudiedin.tohavestudiedB.tostudyC.tobestudyingD.tohavebeenstudying2.Thepurposeofnewtechnologiesistomakelifeeasier,____itmoredifficult.notmakeB.nottomakeC.notmakingD.don’tmake3.I’veworkedwithchildrenbefore,soIknowwhat____inmynewjob.expectedB.toexpectC.tobeexpectingD.expects4.Havingatripabroadiscertainlygoodfortheoldcouple,butitremains____whethertheywillenjoyit.toseeB.tobeseenC.seeingD.see5.ItissaidinAustraliathereismorelandthanthegovernmentknows____.itwhattodowithB.whattodowithitC.whattodoitwithD.todowhatwithit6.Themotherdidn’tknow____toblameforthebrokenglassasithappenedwhileshewasout.A.whoB.whenC.howD.why7.Pauldoesn’thavetobemade____.Healwaysworkshard.A.learnB.tolearnC.learned D.learning8.Weagreed____herebutsofarshehasn’tturnedupyet.A.havingmetB.meetingC.tomeetD.tohavemet9.Theboywantedtoridehisbicycleinthestreet,buthismothertoldhim____.A.nottoB.nottodoC.notdoitD.donotto10.Thepatientwaswarned____oilyfoodaftertheoperation.A.toeatnotB.eatingnotC.nottoeatD.noteating11.Iwouldlove____tothepartylastnightbutIhadtoworkextrahourstofinishareport.A.togoB.tohavegoneC.goingD.havinggone12.CharlesBabbageisgenerallyconsidered____thefirstcomputer.A.toinventB.inventingC.tohaveinventedD.havinginvented13.LittleJimshouldlove____tothetheatrethisevening.A.tobetakenB.totakeC.beingtakenD.taking14.____lateintheafternoon,Bobturnedoffthealarm.A.TosleepB.SleepingC.SleepD.Havingsleep15.Theteacheraskedus____somuchnoise.A.don’tmakeB.notmakeC.notmakingD.nottomakeEx2onPage6rewriting:HewasoverheardtosaythathehopedJohnwouldresign.
