3.作定语的及物动词的现在分词形式有doing和beingdone两种。当被修饰的名词与分词之间为主动关系时,用doing;当被修饰的名词与分词之间为被动关系且表示现在分词的动作与谓语的动作同时进行时,用beingdone;作定语的不及物动词的现在分词形式只有doing。Wecanseetheflowersnoddinggentlyinthewind.我们能看见花在风中轻轻摇曳。Thefilmbeingshowninthecinemaisexciting.正在电影院上映的那部电影很令人激动。 【名师点津】现在分词作定语,要注意现在分词所表示的动作发生的时间。一般说来,主要有下列两种情况:(1)表示与谓语动作同时进行的动作(变为定语从句时要用进行时态)。(2)表示经常性、习惯性的动作或现在(当时)的状态或事实常理(变为定语从句时多用一般现在时或一般过去时)。Didyouseethegirldancingwithyourbrother?→Didyouseethegirlwhowasdancingwithyourbrother?Welivedinaroomfacingthesouth.→Welivedinaroomwhich/thatfacedthesouth.Thefactorymakingthesepensisasmallone.→Thefactorywhich/thatmakesthesepensisasmallone. 二、动名词作定语动名词作定语用于说明被修饰词的用途、功能或目的,常放在被修饰词之前。awalkingstick=astickforwalking拐杖awashingmachine=amachineforwashing洗衣机areadingroom=aroomforreading阅览室Shetrainedfivetimesaweekatherlocalswimmingpool.她一周在当地的游泳池训练五次。 学以致用·随堂检测全达标 Ⅰ.单词拼写1.Thetwohillswiththevalleyformedabeautiful(风景).2.Ifwetaketheshortest(路线),wemaycomeacrossatrafficjam.3.I’mafraidIcan’tgoshoppingwithyoutodaybecauseIdon’thaveenough(现金)now.4.Wehavepreparedabeautiful(纪念品)foryou.5.Ihadalongconversationwithherinthe(咖啡馆).6.Hehasbeentoa(遥远的)villagetodosomevoluntaryworkfortwomonths.landscaperoutecashsouvenircaféremote 7.Tooursurprise,thegirl’s(行李)wasfilledwithbooksinsteadofbeautifulclothes.8.Theplaneistakingoff.Pleasego(登机)rightnow.9.IfIleavenow,Icancatchtheearlier(航班)ontime.10.Only10%ofAmericanseniorpeople(参与)inregularexercise.luggageaboardflightengage Ⅱ.用所给词的适当形式填空1.Atthattime,hungerwasa(disturb)problem.2.Thehospitalnow(build)isexpectedtobecompletedinfiveyears.3.Itiswisetolenda(help)handtothoseinneed.4.The(grow)grassbreaksoutoftheearthinspring.5.Theyrepresenttheearth(come)backtolifeandbestwishesfornewbeginnings.6.Therefore,youcansmelldifferentchemicals(come)outofyournewbook.disturbingbeingbuilthelpinggrowingcomingcoming 7.I’vealsonoticedthattherearesomepeopleofnon-Chinesebackground(attend)theevents.8.Theresearchersareconductingastudy(describe)thetechnology.9.Johnissohappybecausehehasgottheletter(offer)himthejobhehasbeendreamingof.10.Recentlyasurvey(compare)pricesofthesamegoodsintwodifferentsupermarketshascausedheateddebate.attendingdescribingofferingcomparing Ⅲ.语法与写作(用动词-ing形式作定语改写句子)1.ThemanwhoissittingbythefireisTom’sfather.→2.Womenwholookaftersmallchildrenusuallygetpaidbythemonth.→3.Thisisoneoftheproblemswhicharebeingdiscussedatthemeetingatpresent.→ThemansittingbythefireisTom’sfather.Womenlookingaftersmallchildrenusuallygetpaidbythemonth.Thisisoneoftheproblemsbeingdiscussedatthemeetingatpresent. 4.Thebookwhichbelongstohimislyingontheground.→5.Doyouwanttoseethedoctorwhoisworkingonthecasereportintheoffice?→Thebookbelongingtohimislyingontheground.Doyouwanttoseethedoctorworkingonthecasereportintheoffice?
