高考熱點：動詞不定式動詞不定式的構成：todo解讀:動詞不定式雖然不能作謂語動詞用”但仍留著動詞的特征,它可以帶有所需要的賓語或狀語而構成動詞不定式短語,如:tostudyhard,toplaytabletenniso動詞不定式的形式變化語態(tài)般式完成式進行式完成進行式主動tobuildtohavebuilttobebuildingtohavebeenbuilding被動tobebuilttohavebeenbuilt動詞不定式的基本用法：這里只學習不定式做主語,賓語,和狀語的用法”它作定語和賓補的用法與分詞一塊學習。作主語句型：Itis/was+形容詞何數(shù)名詞單數(shù)+todosth解讀1:不定式作主語常見的是it作形式主語,放在句首,將真正的主語動詞不定式（短語）放在句子后面。經(jīng)典例句：1）Ifseasytobewiseaftertheevent.2）Itiseasiertospendmoneythantomakemoney.3）It'sbettertolovesomeoneyoucan'thavethantohavesomeoneyoucan7tlove.4）Itisnotagoodhabittostayuptoolate解讀2:此外開纟式主語it不能用that、this來替換。這也是不定式作主語時的考點。出題句型是:is/was+形容詞何數(shù)名詞單數(shù)+todo此句型特別重要,要牢記。判斷下列句子讀錯，并說明理由：.Thisisimpossibleforpeopletostaredirectlyatthesun...Duetotherefractionoflightrays,thisisimpossibleforthenakedeyetodeterminetheexactlocationofastarclosetothehorizon.解讀3：it作形式主語,不定式可以有自己的邏輯主語,通常用for+名詞（代詞）或of+名詞（代詞）放在不定式的前面。此時不定式的語態(tài)須看與邏輯主語的主被動關系。For與of的區(qū)別是初中內(nèi)容。經(jīng)典例題：Ispossibletoflytothemooninaspaceship?A.thisB.thereC.thatD.itThedoctorthoughtwouldbegoodforyoutohaveaholiday.（2010全國卷II14）.A.thisB.thatC.oneD.itIt'simportantforthefiguresregularly.（2011北京卷）A.tobeupdatedB.tohavebeenupdatedC.toupdateD.tohaveupdated二.作賓語直接作賓語句型：動詞（vt）+todo解讀:直接跟在一個及物動詞后面作賓語。這時句子有以下兩個特點:第_:句子的主語和不定式的邏輯主語是一致的”不定式的語態(tài)需看與句子主語的關系。第二：這時句子的謂語動詞多是描寫態(tài)度；不定式動作則說明行為。經(jīng)典例句：1）Nobodywantstobelaughedat.2）Thiscompanyrefusedtocooperatewithus.經(jīng)典例題：Idon'twantlikeI'mspeakingiiiofanybody,butthemanager'splanisunfair.（2005天津卷）A.tosoundB.tobesoundedC.soundingD.tohavesoundedcan'tstandwithJaneinthesameoffice.Shejustrefusestalkingwhilesheworks.（2006北京卷）A.working;stoppingB.towork;stoppingC.working;tostopD.towork;tostopAsayoungman,Ihateinpublic.A.laughedatB.tobelaughedatC.tolaughatD.laughingat句型：某些及物動詞+連詞+todo_解讀:在一些動詞之后,可以在連接代詞（what,who,which）或連接副詞（how,when,where）及連詞whether后面接一帶to的動詞不定式作賓語。常見的動詞有：ask,decide,explain,forget,五ndout,guess,imagine,know,wonder.經(jīng)典例句：1）Iwonderwhotoinvite.2）Showuswhattodo.3）Idon'tknowwhethertoanswerhisletter.考點解讀：不定式的語態(tài):必須用主動形式,此時易誤選為被動形式。當連接詞為代詞時,不定式為及物動詞,且其后不加賓語。經(jīng)典例題：There7ssomuchdeliciousfood!Ican'tdecided.A.whattoeatB.whentoeatC.howtoeatD.wheretoeatCanyoutellmeontheInternet?A.howtosearchB.howsearchC.wherecanIsearchD.whencanIsearchHetolduswhetherapicnicwasstillunderdiscussion.（2009四丿丨|卷）A.tohaveB.havingC.haveD.had?不定式作賓語后置:如果不定式（賓語）后面有賓語補足語，則用it作形式賓語，真正的賓語（不定式）后置，放在賓語補足語后面，構成句型“動詞+it+賓補（名詞或形容詞）+賓語to經(jīng)典例句：Ithinkiihardtoanswerthequestioninonego.我覺得很難—下子回答這個問題。Hefeelsitchallengingtobeamarketingsupervisor.經(jīng)典例題：Usingmanysymbolsmakestoputalargeamountofinformationonasinglemap.A.possibleB.itispossibleC.itpossibleD.thatpossibleThechairmanthoughtnecessarytoinviteProfessorSmithtospeakatthemeeting.（2005全國卷1）A.thatB.itC.thisD.himAsthebusiestwomaninNorton,shemadeherdutytolookafteralltheotherpeople'saffairsinthattown.（2006湖南卷）A.thisB.thatC.oneD.itrdappreciateifyouwouldliketoteachmehowtousethecomputer.（2006山東卷）A.thatB.itC.thisD.youThefactthatshewasforeignmadedifficultforhertogetajobinthatcountry.（2010遼寧卷33）A.soB.muchC.thatD.itThetwogirlsaresoalikethatstrangersfinddifficulttotellonefromtheother.（2011山東卷）A.itB.themC.herD.thatNewtechnologieshavemadepossibletoturnoutnewproductsfasterandatalowercost.[2012四川】A.thatB.thisC.oneD.it三.狀語構成以下幾種句型句型1:形容詞+todo（語言山表述為:形容詞后面的動詞不定式）解讀1:該形容詞為表示動作特點的形容詞時,一般做兩種成分:表語和賓補★當該形容詞作表語時”句子主語和不定式動詞可構成邏輯上的動賓關系。★當該開纟容詞作賓補時”句子賓語和不定式動詞可構成邏輯上的動賓關系。經(jīng)典例1）Sheisverynicetotalkto.2）Maryiseasytogetonwith.3）IfindEnglishdifficulttospeak.4）IfindFootballveryinterestingtowatch.★此句型三大考點不定式動詞一般不用被動形式:（最容易出錯）不定式后不能再加賓語:不定式動詞所帶的介詞不能省略：經(jīng)典例題：Tomaskedthecandymakersiftheycouldmakethechocolateeasierintosmallpieces.（2011安徽卷）A.breakB.breakingC.brokenD.tobreakThismachineisveryeasy.Anybodycanlearntouseitinafewminutes.[2012遼寧】A.operatingB.tobeoperatingC.operatedD.tooperated解讀2:在本句型中,如果形容詞是表示人的性格特征（如:brave,careful,clever,considerate,foolish,generous,kind，等）或情緒感受（happy；surprised；glad；honored）的詞。句子主語或賓語和不定式動詞可構成邏輯上的主謂關系.經(jīng)典例句：1）Hewaskindtohelpus.2）Theboywascarelesstobreakthewindow.3）Wethinktheboycarelesstobreakthewindow.經(jīng)典例題：Theoldmansatinfrontofthetelevisioneveryevening,happyanythingthathappenedtobeon.[2012全國卷II】A.towatchB.watchingC.watchedD.tohavewatchedfeelgreatlyhonoredintotheirsociety.（2008北京卷）A.towelcomeB.welcomingC.tobewelcomedD.welcomedWewereastonishedthetemplestillinitsoriginalcondition.（2010遼寧卷）A.findingB.tofindC.findD.tobefoundThedifferenceinthicknessandweightfromtheearlierversionmakestheiPad2morecomfortable.（2011福建卷）A.heldB.holdingC.beheldD.tohold句型2:不定式作目的狀語，可構成句型：Todo/Inordertodosth,主語+謂語或主語+謂語+todo/inordertodo/soastodo.經(jīng)典例句：Hatingpeopleislikeburningdownyourownhousetogetredofarat.]Toacquireknowledge,onemuststudy;buttoacquirewisdom,onemustobserve.Wehadbetterstartearlytocatchthetrain.Wehadbetterstartearlysoastocatchthetrain.wenttothepostofficeinordertomailaletter.經(jīng)典解讀：soasto—般不用在句首。但todo或inordertodo可提到句首。目的狀語放在句首時,和句子之間要有“,”間隔；當目的狀語位于句末時,和句子之間不可以有“,”間隔。不定式的語態(tài):看與句子主語的關系:主動todo；被動tobedoneo
