高中英语人教版课件 必修4 Unit 4 Period 3 Grammar

Unit4BodyLanguageGrammar本课件主要介绍动词-ing形式作定语和状语，做练习启发学生思考，通过示例引导学生总结出动词-ing形式在什么情况下作状语或定语。举例说明如果动词-ing形式出现在名词前后，并修饰该名词，一般作定语，该定语可变为介词短语或定语从句。举例说明如果动词-ing形式用于修饰某动词或整个句子时作状语，可变换为状语从句。作状语时对谓语起修饰和陪衬作用，表示时间，原因，条件，让步，结果，方式或伴随情况。最后让学生做练习，题型涉及造句，填空，改错和单选，让学生当堂完成，及时巩固。Grammar

一:V-ing形式由

“do＋ing”

构成,其否定形式是

“notdoing”,V-ing可以带宾语或状语构成

V-ing短语,没有人称和数的变化,但有时态和语态的变化。V-ing形式语态时态主动语态被动语态一般式完成式(not)doing(not)beingdone(not)havingdone(not)havingbeendoneV-ing形式在句中作定语和状语是本单元的学习重点。1.作定语

V-ing形式可以单独充当名词的前置修饰语,这时有两种情况。-ing形式表示“供作......之用”的意思,这类作定语的-ing形式过去叫动名词。

Aswimmingpool=apoolforswimmingAsleepingcar=acarforsleeping2)

-ing形式表示“......的”意思,过去叫现在分词

Asleepingchildworkingpeopletherisingsun-ing形式短语作定语时一般放在它所修饰的名词之后,相当于一个定语从句。如:Theyarevisitorscomingfromseveralcountries.Theboystandingthereisaclassmateofmine.2.作状语可以表示时间,原因,结果,条件,行为方式或伴随动作等。Usingyourhead,you’llfindagoodway.条件1)Fourpeopleenteredtheroomlookingaroundinacuriousway.=Fourpeopleentertheroomandlookedaroundinacuriousway.(伴随动作)

2)Beingpoor,hecouldn’taffordaTVset.

(原因)3)Workinghard,you’llsurelysucceed.条件4)Theboysatinfrontofthefarm-house,cuttingthebranch.伴随5)Hecamerunningbacktotellmethenews.方式6)(When)Hearingthenews,hegotfrightened.=Whenheheardthenews,hegotfrightened.(时间,可以在分词前保留when)

7)Thechildslippedandfell,hittinghisheadagainstthedoor.结果AttentionPlease-ing形式作状语时,它的逻辑主语必须与主句的主语是一致的。Timepermitting,Iwillpayavisittothewholecity.

(分词的逻辑主语是time,而句子的主语是I,两者不构成主谓关系,所以只能用独立主格结构,也就是给现在分词补充一个主语。)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单句改错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
