高二英语Scienceversusnature教案
Verb-edform
一、V-ed分词具有形容词和副词性质,在句中可充当定语、表语、宾语补语、状语。
1.作定语
过去分词作定语,表示已经完成的被动的动作或状态,但不及物动词构成的过去分词只表示完成,而不表示被动意义。
例如:完成+被动:apollutedriveralockedroomawell-educatedman
只有完成:aretiredworkerafallenleafboiledwater
作定语的V-ed分词也有前置和后置两种情况。单个过去分词作定语,常常位于被修饰的名词前;而过去分词短语作定语时,常常位于被修饰的名词后面,相当于一个定语从句。
Eg.1).Youshouldimproveyourspoken(speak)English.
2).What’sthelanguagespoken(speak)inthatarea?
=.What’sthelanguagewhich/thatisspoken(speak)inthatarea?
3).Thefiremenweretryingtorescuethepeopletrappedinthefire.
=Thefiremenweretryingtorescuethepeoplewhowastrappedinthefire.
4).Themeeting,attendedbyonethousandstudents,wasasuccess.
=Themeeting,whichwasattendedbyonethousandstudents,wasasuccess.
2.作表语
作表语的V-ed分词大多转化成为形容词,通常用于联系动词之后(例如be,seem,appear,look,sound,feel,remain,stay,become,get等),表示主语所处的状态
1).Edisonbecameinterested(interest)insciencewhenhewasveryyoung.
2).Shelooksveryexcited(excite)atthenews.
3).WhenIwascleaningthewindow,myfingergotcut(cut)unexpectedly.
3.作宾语补足语
如果宾语与后面作宾补的动词构成被动关系,则使用V-ed分词作宾补。可以带V-ed分词作宾补的词有:with,see,watch,observe,notice,lookat,hear,listento,feel,sense,find,leave,keep,get,have,make.
1).Ihadmymoneystolen(steal)onthebus.
2).AsheknowslittleEnglish,hefindsitdifficulttomakehimselfunderstood(understand).
3).Inthemorning,peoplewokeupandfoundtheworldoutsidetheirhousescompletelychanged(change).
4.作状语
作状语的V-ed分词与主句之间常有逗号隔开,在句中可表示时间,原因,条件,让步,伴随等情况,并可转化为相应的状语从句。作状语的V-ed和主句的主语常有被动关系。
1)时间状语
Seenfromspace,theearthlooksblue.
=Whentheearthisseenfromspace,itlooksblue.
Askedwhathadhappened,heloweredhishead.
=Whenhewasaskedwhathadhappened,heloweredhishead.
2)原因状语
Bornintoapoorfamily,hehadonlytwoyearsofschooling.
=Ashewasbornintoapoorfamily,hehadonlytwoyearsofschooling.
Becausetheyweremovedbythestory,theydecidedtohelpher.
=Movedbythestory,theydecidedtohelpher.
3)条件状语
Givenmoretime,wearesuretofinishit.
=Ifwearegivenmoretime,wearesuretofinishit.
Comparedwithotherprofessors,sheisanexcellentspeaker.
=.
4)让步状语
Laughedatbyeverybody,hehadmysympathy.
=Thoughhewaslaughedatbyeverybody,hehadmysympathy.
Eventhoughhewasdefeatedbyhisopponent,hestillisaheroinmyheart.
=Defeatedbyhisopponent,hestillisaheroinmyheart.
5)伴随状语
Theboysatatthetableburiedinhishomework.
=Theboysatatthetableandhewasburiedinhishomework.
Thegirllayinbedlostinthought.
=Thegirllayinbedandshewaslostinthought.
Iwillspendthenightlocked(lock)inyourroom.
Shelefttherestaurant,disappointed(disappoint)withthebadservice.
二、转化为形容词的V-ed
有一些过去分词已转化为形容词,失去被动意义,仅表状态。如:hidden,dressed,lost,seated,determined,absorbed,injured,based,surprised,satisfied,bored,tired…
e.gWhatmadeyousofrightened?
Thedog,boredwiththegame,willnotplayanymore.
=Thedog,whichisboredwiththegame,willnotplayanymore.
Muchinterested,heagreedtogiveitatry.
=Ashewasmuchinterested,heagreedtogiveitatry.
Seatedinthecar,thePresidentwavedtothecrowd.
=Whilehewasseatedinthecar,thePresidentwavedtothecrowd.
三、连词+V-ed
过去分词有时和连词(when,while,whenever,until,if,unless,once,though,
although,eventhough/if)一起用,相当于状语从句的紧缩式。
(注意:before/after后不直接跟V-ed分词,而用before/after+beingdone,因为此时分词前的before/after是介词。)
Ifaccepted(accept)forthispost,youwillbeinformedbyMay1st.
Unlesschanged(change),thislawwillmakelifedifficultforfarmers.
Iwillnotgiveupmyplaneveniftold(tell)to.
Thesemachinesmustbecheckedbeforebeingused(use).
四、tobedone,beingdone,done,havingbeendone作定语的区别:
以上四种形式都表示被动,都可作定语。tobedone表示即将被…;beingdone表示正在被…;done表示被做过了…;havingbeendone作非限制性定语,和被修饰词用逗号隔开,强调在谓语动词的动作之前完成。
Thequestiontobediscussed(discuss)tomorrowinvolvespollution.
Thequestiondiscussed(discuss)yesterdayinvolvespollution.
Thequestionbeingdiscussed(discuss)nowinvolvespollution.
Thequestion,havingbeendiscussed(discuss)foryears,involvespollution.
五、done,havingbeendone作状语的区别:
beingdone一般在句中不作状语,而用done代替之。havingbeendone强调动作在谓语动作之前完成,或已经持续一段时间的动作,常用作时间和原因状语,done则不强调时间先后和持续一段时间。
Led(lead)bythelocalguide,wewentfurtherintotheforest.
Havingbeentaken(take)goodcareofforhalfayear,thepatientbecamefarbetter.
Havingbeentranslated(translate)intomanylanguages,thenoveliswell-knownthroughouttheworld.
