一:V-ing形式由

“do＋ing”

構(gòu)成,其否定形式是

“notdoing”,V-ing可以帶賓語(yǔ)或狀語(yǔ)構(gòu)成

V-ing短語(yǔ),沒(méi)有人稱和數(shù)的變化,但有時(shí)態(tài)和語(yǔ)態(tài)的變化。V-ing形式語(yǔ)態(tài)時(shí)態(tài)主動(dòng)語(yǔ)態(tài)被動(dòng)語(yǔ)態(tài)一般式完成式(not)doing(not)beingdone(not)havingdone(not)havingbeendoneV-ing形式在句中作定語(yǔ)和狀語(yǔ)是本單元的學(xué)習(xí)重點(diǎn)。1.作定語(yǔ)

V-ing形式可以單獨(dú)充當(dāng)名詞的前置修飾語(yǔ),這時(shí)有兩種情況。-ing形式表示“供作......之用”的意思,這類作定語(yǔ)的-ing形式過(guò)去叫動(dòng)名詞。

Aswimmingpool=apoolforswimmingAsleepingcar=acarforsleeping2)

-ing形式表示“......的”意思,過(guò)去叫現(xiàn)在分詞

Asleepingchildworkingpeopletherisingsun-ing形式短語(yǔ)作定語(yǔ)時(shí)一般放在它所修飾的名詞之后,相當(dāng)于一個(gè)定語(yǔ)從句。如:Theyarevisitorscomingfromseveralcountries.Theboystandingthereisaclassmateofmine.2.作狀語(yǔ)可以表示時(shí)間,原因,結(jié)果,條件,行為方式或伴隨動(dòng)作等。Usingyourhead,you’llfindagoodway.條件1)Fourpeopleenteredtheroomlookingaroundinacuriousway.=Fourpeopleentertheroomandlookedaroundinacuriousway.(伴隨動(dòng)作)

2)Beingpoor,hecouldn’taffordaTVset.

(原因)3)Workinghard,you’llsurelysucceed.條件4)Theboysatinfrontofthefarm-house,cuttingthebranch.伴隨5)Hecamerunningbacktotellmethenews.方式6)(When)Hearingthenews,hegotfrightened.=Whenheheardthenews,hegotfrightened.(時(shí)間,可以在分詞前保留when)

7)Thechildslippedandfell,hittinghisheadagainstthedoor.結(jié)果AttentionPlease-ing形式作狀語(yǔ)時(shí),它的邏輯主語(yǔ)必須與主句的主語(yǔ)是一致的。Timepermitting,Iwillpayavisittothewholecity.

(分詞的邏輯主語(yǔ)是time,而句子的主語(yǔ)是I,兩者不構(gòu)成主謂關(guān)系,所以只能用獨(dú)立主格結(jié)構(gòu),也就是給現(xiàn)在分詞補(bǔ)充一個(gè)主語(yǔ)。)theBritishladytheColumbiantheJapanesetheCanadianYouseeherstepbackappearingsurprised.HisnosetouchesMr.Cook’smovinghand.Youseeherstepbackappearingsurprised.=Youseeherstepbackandsheappearssurprised.Theyalsoexpresstheirfeelingsusingunspokenlanguage.=Theyalsoexpresstheirfeelingsbythewayofusingunspokenlanguage.HisnosetouchedMr.Cook’smovinghand.=HisnosetouchedMr.Cook’shandwhichismoving.=Theyarevisitorswhocomefromseveralcountries.Theyarevisitorscomingfromseveralcountries.=Thisisanexperiencewhichisexciting.Thisisanexcitingexperience.1.WhenheapproachedMsSmith,hetouchedhershoulderandkissedher._________________MsSmith,hetouchedhershoulderandkissedher.Rewritethefollowingsentences.Whenapproaching2.Thepersonwhoistranslatingthesongscanspeaksevenlanguages.Theperson__________________canspeaksevenlanguages.translatingthesongs3.Theboystandingthereisreadingabookaboutbodylanguage.Theboy______________thereisreadingabookaboutbodylanguage.whoisstanding4.BecausehecomesfromJordan,hemovesclosetoaskyouaquestion.____________Jordan,hemovesclosetoaskyouaquestion.Comingfrom5.Shesatatthedeskanddidherhomework.Shesatatthedesk____________________.doingherhomeworkUsingstructureshold…inarms,cry,appearsadThewomanholdshersoninarms,cryingandappearingverysad.Thewomancriesloudly,holdinghersoninarms.box,hitontheface,move,stepsThetwoboxingmentrytohittheotherontheface,movingtheirstepscarefully.ski,laugh,excitingMickeyandMimiareskiingdownthehill,laughingalltheway.Whatanexcitingsceneitis!dance,sing,raisearmsup,amazingmusicMickeyandMimiaredancingtoamazingmusic,singingandraisingtheirarms.KoalaBear,carry,climb,searchforfoodCarryingherlittlebabyontheback,themotherKoalaBearclimbsupthetrees,searchingforfood.1.Havingnotseenthefilm,Ican’ttellyouwhatIthinkofit.2.Themenworkedforextrahoursgotanextrapay.3.Seenfromthetopofthehill,wefindthecitymorebeautiful.4.Generallyspeak,facialexpressionsarehelpfulcommunications,too.NothavingworkingSeeingspeaking單句改錯(cuò)5.“Can’tyouread?”themansaid,angrilypointedtothenoticeonthewall.6.Knockingatthedoorbeforeentering,please.7.Europeanfootballisplayedin80countries,madeitthemostpopularsportintheworld.pointingKnockmaking1.Thestrangersaidsomethingina_______voiceandthelittlegirlwasverymuch________A.frightening,frightenedB.frightened,frighteningC.frightening,frighteningD.frightened,frightenedChoosethebestanswer.2.________thepiano,someonesuddenlyknockedatthedoor.A.PlayingB.WhenIwasplayingC.RepairingD.Examining3.Mothercaughttheboy______inthecorner.A.smokeB.tosmokeC.beingsmokedD.smoking4.______theprogramme,theyhavetostaythereforanother2weeks..A.NotcompletingB.NotcompletedC.NothavingcompletedD.Havingnotcompleted5.“Wecan’tgooutinthisweather”,saidBob,____outofthewindow.A.lookingB.tolookC.lookedD.havinglooked6.Though_____money,hisparentsmanagedtosendhimtouniversity.A.lackedB.lackingofC.lackingD.lackedin7.Thebell_______theendoftheperiodrang,______ourheateddiscussion.A.indicating;interruptingB.indicated;interruptingC.indicating;interruptedD.indicated;interrupted8._______suchheavypollutionalready,itmaynowbetoolatetocleanuptheriver.A.HavingsufferedB.SufferingC.TosufferD.Suffered9.Helookedaroundandcaughtaman______hishandintothepocketofapassenger.A.putB.tobeputtingC.toputD.putting10.Suddenly,atallmandrivingagoldencarriage_____thegirlandtookheraway,____intothewoods.A.seizing;disappeared
