过去分词作状语【教学内容】过去分词作状语【教学目标】熟练掌握过去分词作状语的用法【教学重难点】和现在分词作状语时的区别【教学过程】*过去分词作状语，表示动作发生的背景或情况，在意义上相当于一个状语从句。过去分词在句中作状语可以作状语可以表示时间、条件、方式、让步、原因、结果等。*动词的-ed形式：与句中主语为逻辑上的被动关系一、表示时间动词的-ed形式可置于句首，也可置于句尾，有时还可以置于主语和谓语之间例：当问到有关他的家庭情况时，他没有回答。.Whenhewasaskedabouthisfamily,hemadenoanswer.—Askedabouthisfamily,hemadenoanswer.—He,askedabouthisfamily,madenoanswer.—Hemadenoanswer,askedabouthisfamily.【活学活用】把下列状语从句改为过去分词作时间状语.Whenhewasaskedwhyhewaslate,hewentred.第1页/共11页—Askedwhyhewaslate,hewentred..Whenwaterisheated,waterchangesintosteam.—Heated,waterchangesintosteam.二、表示条件表条件的状语常位于句首例：从远处看，这个村庄看上去更漂亮。1.IfthevillageisSeeninthedistance,thevillagelooksmorebeautiful.—Seeninthedistance,thevillagelooksmorebeautiful.【随即随练】把下列状语从句改为过去分词作条件状语1.Ifweweregivenmoretimeandmoney,wewouldhavedonetheworkbetter.—Givenmoretimeandmoney,wewouldhavedonetheworkbetter.2.IfIwascomparedwithyou,Istillhavealongwaytogo.—Comparedwithyou,Istillhavealongwaytogo.三、表示原因表示原因的分词短语一般置于句首，偶尔置于句尾或句中例：1.由于伤得严重，只好把他送往医院。Becausehewasseriouslyinjured,hehadtobetakentohospital.—Seriouslyinjured,hehadtobetakentohospital.第2页/共11页【小试牛刀】把下列状语从句改为过去分词作原因状语l.Becausethechildrenweredeeplymovedbythestory,thechildrenbegantocry.—Deeplymovedbythestory,thechildrenbegantocry.2.Thechildlearnsfast,becausethechildiswellbroughtupbyhisparents.—Thechildlearnsfast,wellbroughtupbyhisparents.四、表示伴随/方式这种状语可置于句首、句中或句尾综上所述，试着把下列的状语从句改为过去分词作伴随或方式状语.猎人在森林里慢慢走着，后面跟着一条狗。Thehunterwalkedslowlyintheforestandhewasfollowedbyhisdog.—Thehunterwalkedslowlyintheforest,followedbyhisdog.—Followedbyhisdog,thehunterwalkedslowlyintheforest.—Thehunter,followedbuhisdog,walkedslowlyintheforest..他失望地走开了。Hewentaway,disappointed.—Hewentawayandhewasdisappointed.五、表示让步尝试把下列状语从句改为用过去分词作让步状语第3页/共11页1.虽然被对方的队打败了，但我们并没有灰心而是相互鼓励。Thoughwewerebeatenbytheoppositeteam,wedidn,tloseheartandencouragedeachother.—Beatenbytheoppositeteam,wedidn,tloseheartandencouragedeachother.2.虽然受伤了，但那个勇敢的战士依然继续作战。Wounded,thebravesoldiercontinuedtofight.—Thoughhewaswounded,thebravesoldiercontinuedtofight.*特别提示*①根据需要，-ed形式前面也可加上when,while,until,once,though,although,aslongas,solongas,unless,asif,asthough,evenif,eventhough等连词例：1.Whenaskedifhehadanydrugswithhim,heclaimedhewasclean.当问他身上是否藏有毒品时，他声称没有。.Unlessinvited,Iwon,tattendtheget-together.除非受到邀请，否则我不会参加聚会。.Theboylefttheplayhousewithoutbeingseen.这个男孩离开了游戏室没有被人发现。②有些过去分词已经形容词化，作状语时表示人的状态或动作的完成。常见的有：satisfied,surprised,interested,moved,worried,pleased,disappointed等。第4页/共11页例：l.Disappointedattheexaminationresults,thegirlstoodtherewithoutsayingaword.因为对考试结果很失望，小女孩站在那儿一句话也没说。.Finallytheyarrivedthehotel,tiredandhungry.最后，他们到达了那家宾馆，又累又饿。③过去分词（短语）作状语时，分词的逻辑主语与句子的主语要一致。例:小偷如果被抓，会受到警方的处理。1.Ifcaught,thepolicewillpunishthethief.（误）2.Ifcaught,thethiefwillbepunishedbythepolice.（正）【牛刀小试】判断下列句子的正误.Foundhimangry,Ibegantotelljokes.（x）（found与I在这个句中不是被动关系）.Findinghimangry,Ibegantotelljokes.（v）.Lookingaround,therewasnoonenearby.（x）（lookaround的逻辑主语不是noone，故本句不成立）.Lookingaround,Ifoundtherewasnoonenearby.（v）▼动词的-ing形式、动词的-ed形式和不定式皆可作状语，区别如下：1）表方式或伴随时作方式或伴随状语时常用动词的-ed形式，习惯上不用-ing形式一般式的被动语态，即不用beingdone形式第5页洪11页例：l.Manyparentswerewalkingaboutthezoo,followedbytheirchildren.很多父母在动物园里游玩，后面紧跟着自己的孩子。2.Ledbyaschoolgirl,theblindmancrossedtheroad.这个盲人由一个女学生领着穿过了马路。2）表示时间作时间状语时，动词的-ed形式如果同时表示被动和完成，常可换用现在分词的被动完成式；如果只表示被动，不表示完成，则不可换用。例：1.Readmanytimes（=havingbeenredmanytimes）,thecrabbedstoryseemsmucheasier.读过多遍，这个深奥的故事似乎变得容易多了。（表示被动和完成）2.Seenfromthetopofthehill,theparklooksmorebeautiful.从山顶上看，这个公园显得更加美丽。（表示被动）3）表示“为了……”，常用不定式作状语，状语动词动作发生时间与句子谓语动作时间相比，是将来。例：Tosleeplateinthemorning,Bobturnedoffthealarm为了明天早上可以睡得晚点，Bob把闹钟关了。【随堂练习】单项选择.“Youcan,tcatchme!”Janeshouted, Baway.A.run B.running C.torun第6页/共11页
