二、合作探究
【观察例句】从课文中找出与划线句子意思相同的句子。

____________________________________,Iwasunsettledforthefirstfewdays.
②WhileIwasconfusedbythenewsurroundings,Iwashitbythelackoffreshair.

【自我归纳】
从上述例句总结出,过去分词在句中可以作__________,进一步说明谓语动词的动作和状态,其逻辑主语通常就是___________________,过去分词与主语之间是__________关系。
三、解难答疑
【知识精析】过去分词作状语,相当于一个状语从句,表明原因、时间、条件等。
(1)作原因状语
过去分词作原因状语时,可转换为as,since或because等引导的状语从句。
Tiredbythetrip,hesoonfellasleep.
=Becausehewastiredbythetrip,hesoonfellasleep.
Lostinthought,healmostranintoacar.
=Ashewaslostinthought,healmostranintoacar.
Encouragedbytheprogresshehasmade,heworksharder.
=_______________________________________________________________.
(2)作时间状语
过去分词作时间状语时,可转换为when,while或after等引导的状语从句。
Seenfromthehill,thecitylookslikeagarden.
=Whenthecityisseenfromthehill,itlookslikeagarden.
Don’tspeakuntilspokento.
=Don’tspeakuntilyouarespokento.
(3)作条件状语
过去分词作条件状语时,可转换为if,once或unless等引导的状语从句。
Givenmoretime,Iwouldhaveworkedouttheproblem.
=IfIhavebeengivenmoretime,Iwouldhaveworkedouttheproblem.
Oncepublished,thedictionarywillbeverypopular.
=Onceitispublished,thedictionarywillbeverypopular.
Comparedwithyourprogress,mineisnothing.
=__________________________________________________________________.
(4)作伴随状语
过去分词作伴随状语时,一般可转换为并列结构。
AuntWucamein,followedbyherdaughter.
=AuntWucamein,and(she)wasfollowedbyherdaughter.
Theteachercamein,followedbysomestudents.
=__________________________________________________________________.
(5)作让步状语
过去分词作让步状语时,可转换为although,though或evenif等引导的状语从句。
Althoughexhaustedbytheclimb,wecontinuedourjourney.
=Althoughwewereexhaustedbytheclimb,wecontinuedourjourney.
Thedogremainedfaithfultoitsownerthoughtreatedbadly.
=Thedogremainedfaithfultoitsownerthoughitwastreatedbadly.
Beatenbytheoppositeteam,theplayerswerenotdiscouraged.
=_________________________________________________________________.
(6)作方式状语
过去分词作方式状语时,如有连词asif,就可转换为asif引导的方式状语从句;若无连词,则可转换为并列结构。
Hebegantocryasifbittenbyasnake.
=Hebegantocryasifhewerebittenbyasnake.
【小试牛刀】
把下列划线部分中的状语改写成状语从句。
①Askedwhathadhappened,hetoldusaboutit.
__________________________________________,hetoldusaboutit.
②Wellknownforhisexpertadvice,hereceivedmanyinvitationstogivelectures.
__________________________________________,hereceivedmanyinvitationstogivelectures.
③Givenmoretime,wewouldbeabletodotheworkmuchbetter.
______________________________,wewouldbeabletodotheworkmuchbetter.

___________________________________,thebookbecameverypopularamongChineseteenagers.
⑤Deeplyinterestedinmedicine,shedecidedtobecomeadoctor.
___________________________________,shedecidedtobecomeadoctor.
⑥Leftaloneathome,Samdidnotfeelafraidatall.
___________________________________,Samdidnotfeelafraidatall.
⑦Unitedwestand,dividedwefail.
____________________,westand.____________________,wefail.
3.【注意】
(1)分词短语作状语时,通常与主句中的主语在逻辑上一致,但有时它也可以有自己独立的逻辑上的主语,这种结构称为独立主格结构。
Hergrandfatherbeingill,shehadtostayathomelookingafterhim.
Timepermitting,youcanpayavisittosomeplacesofinterestinHangzhou.
Theworkfinished,wewenthome.
(2)speaking和judging作悬垂状语时,不需和句子的主语保持一致。
Generallyspeaking,womenlivelongerthanmen.
一般来说,女人比男人长寿。
Strictlyspeaking,itisn’tacorrectanswer.
严格地说,这不是正确答案。
Judgingbyherlook,shewasdisappointed.
从她的表情看,她很失望。
(3)considering“考虑到”,形式上是分词,可以用作介词。
Consideringthedistance,hearrivedearly.
考虑到这么远的路程,他是来得早的。
(4)given“考虑到”,“如果有”,形式上是分词,可以用作介词。
Giventhechance,IwouldcometoseeyouinAustralia.
如果有机会,我愿意来澳大利亚看你。
Giventheirinexperience,theyhavedoneagoodjob.
考虑到他们没有经验,他们已经干得很好了。
Giventhegeneralstateofhishealth,itmaytakehimawhiletorecoverfromtheoperation.
考虑到他的健康状况,手术后康复还需要一段时间。
4.现在分词与过去分词作状语的区别
(1)过去分词与句子的主语之间存在逻辑上的动宾关系,即表被动;现在分词与句子的主语之间存在逻辑上的主谓关系,即表主动。
Askedwhyhewaslate,hecried.
被问到他为什么迟到时,他哭了。
Lookingoutofthewindow,Isawsomestudentsplayingthere.
我朝窗外望去,看见几个学生在那边玩耍。
Followingtheoldman,wewentupstairs.—wefollowed
跟着那个老人,我们上去了。
Followedbytheoldman,wewentupstairs.
被那个老人跟着,我们上去了。
