過去分詞作狀語【教學內容】過去分詞作狀語【教學目標】熟練掌握過去分詞作狀語的用法【教學重難點】和現(xiàn)在分詞作狀語時的區(qū)別【教學過程】*過去分詞作狀語，表示動作發(fā)生的背景或情況，在意義上相當于一個狀語從句。過去分詞在句中作狀語可以作狀語可以表示時間、條件、方式、讓步、原因、結果等。*動詞的-ed形式：與句中主語為邏輯上的被動關系一、表示時間動詞的-ed形式可置于句首，也可置于句尾，有時還可以置于主語和謂語之間例：當問到有關他的家庭情況時，他沒有回答。.Whenhewasaskedabouthisfamily,hemadenoanswer.—Askedabouthisfamily,hemadenoanswer.—He,askedabouthisfamily,madenoanswer.—Hemadenoanswer,askedabouthisfamily.【活學活用】把下列狀語從句改為過去分詞作時間狀語.Whenhewasaskedwhyhewaslate,hewentred.第1頁/共11頁—Askedwhyhewaslate,hewentred..Whenwaterisheated,waterchangesintosteam.—Heated,waterchangesintosteam.二、表示條件表條件的狀語常位于句首例：從遠處看，這個村莊看上去更漂亮。1.IfthevillageisSeeninthedistance,thevillagelooksmorebeautiful.—Seeninthedistance,thevillagelooksmorebeautiful.【隨即隨練】把下列狀語從句改為過去分詞作條件狀語1.Ifweweregivenmoretimeandmoney,wewouldhavedonetheworkbetter.—Givenmoretimeandmoney,wewouldhavedonetheworkbetter.2.IfIwascomparedwithyou,Istillhavealongwaytogo.—Comparedwithyou,Istillhavealongwaytogo.三、表示原因表示原因的分詞短語一般置于句首，偶爾置于句尾或句中例：1.由于傷得嚴重，只好把他送往醫(yī)院。Becausehewasseriouslyinjured,hehadtobetakentohospital.—Seriouslyinjured,hehadtobetakentohospital.第2頁/共11頁【小試牛刀】把下列狀語從句改為過去分詞作原因狀語l.Becausethechildrenweredeeplymovedbythestory,thechildrenbegantocry.—Deeplymovedbythestory,thechildrenbegantocry.2.Thechildlearnsfast,becausethechildiswellbroughtupbyhisparents.—Thechildlearnsfast,wellbroughtupbyhisparents.四、表示伴隨/方式這種狀語可置于句首、句中或句尾綜上所述，試著把下列的狀語從句改為過去分詞作伴隨或方式狀語.獵人在森林里慢慢走著，后面跟著一條狗。Thehunterwalkedslowlyintheforestandhewasfollowedbyhisdog.—Thehunterwalkedslowlyintheforest,followedbyhisdog.—Followedbyhisdog,thehunterwalkedslowlyintheforest.—Thehunter,followedbuhisdog,walkedslowlyintheforest..他失望地走開了。Hewentaway,disappointed.—Hewentawayandhewasdisappointed.五、表示讓步嘗試把下列狀語從句改為用過去分詞作讓步狀語第3頁/共11頁1.雖然被對方的隊打敗了，但我們并沒有灰心而是相互鼓勵。Thoughwewerebeatenbytheoppositeteam,wedidn,tloseheartandencouragedeachother.—Beatenbytheoppositeteam,wedidn,tloseheartandencouragedeachother.2.雖然受傷了，但那個勇敢的戰(zhàn)士依然繼續(xù)作戰(zhàn)。Wounded,thebravesoldiercontinuedtofight.—Thoughhewaswounded,thebravesoldiercontinuedtofight.*特別提示*①根據(jù)需要，-ed形式前面也可加上when,while,until,once,though,although,aslongas,solongas,unless,asif,asthough,evenif,eventhough等連詞例：1.Whenaskedifhehadanydrugswithhim,heclaimedhewasclean.當問他身上是否藏有毒品時，他聲稱沒有。.Unlessinvited,Iwon,tattendtheget-together.除非受到邀請，否則我不會參加聚會。.Theboylefttheplayhousewithoutbeingseen.這個男孩離開了游戲室沒有被人發(fā)現(xiàn)。②有些過去分詞已經形容詞化，作狀語時表示人的狀態(tài)或動作的完成。常見的有：satisfied,surprised,interested,moved,worried,pleased,disappointed等。第4頁/共11頁例：l.Disappointedattheexaminationresults,thegirlstoodtherewithoutsayingaword.因為對考試結果很失望，小女孩站在那兒一句話也沒說。.Finallytheyarrivedthehotel,tiredandhungry.最后，他們到達了那家賓館，又累又餓。③過去分詞（短語）作狀語時，分詞的邏輯主語與句子的主語要一致。例:小偷如果被抓，會受到警方的處理。1.Ifcaught,thepolicewillpunishthethief.（誤）2.Ifcaught,thethiefwillbepunishedbythepolice.（正）【牛刀小試】判斷下列句子的正誤.Foundhimangry,Ibegantotelljokes.（x）（found與I在這個句中不是被動關系）.Findinghimangry,Ibegantotelljokes.（v）.Lookingaround,therewasnoonenearby.（x）（lookaround的邏輯主語不是noone，故本句不成立）.Lookingaround,Ifoundtherewasnoonenearby.（v）▼動詞的-ing形式、動詞的-ed形式和不定式皆可作狀語，區(qū)別如下：1）表方式或伴隨時作方式或伴隨狀語時常用動詞的-ed形式，習慣上不用-ing形式一般式的被動語態(tài)，即不用beingdone形式第5頁洪11頁例：l.Manyparentswerewalkingaboutthezoo,followedbytheirchildren.很多父母在動物園里游玩，后面緊跟著自己的孩子。2.Ledbyaschoolgirl,theblindmancrossedtheroad.這個盲人由一個女學生領著穿過了馬路。2）表示時間作時間狀語時，動詞的-ed形式如果同時表示被動和完成，?？蓳Q用現(xiàn)在分詞的被動完成式；如果只表示被動，不表示完成，則不可換用。例：1.Readmanytimes（=havingbeenredmanytimes）,thecrabbedstoryseemsmucheasier.讀過多遍，這個深奧的故事似乎變得容易多了。（表示被動和完成）2.Seenfromthetopofthehill,theparklooksmorebeautiful.從山頂上看，這個公園顯得更加美麗。（表示被動）3）表示“為了……”，常用不定式作狀語，狀語動詞動作發(fā)生時間與句子謂語動作時間相比，是將來。例：Tosleeplateinthemorning,Bobturnedoffthealarm為了明天早上可以睡得晚點，Bob把鬧鐘關了?！倦S堂練習】單項選擇.“Youcan,tcatchme!”Janeshouted, Baway.A.run B.running C.torun第6頁/共11頁
