ReferenceforTeaching

现在分词和过去分词的区别现在分词和过去分词主要差别在于:现在分词表示“主动和进行”,过去分词表示“被动和完成”(不及物动词的过去分词不表示被动,只表示完成)。分词可以有自己的状语、宾语或逻辑主语等。?1.单个分词作定语一般放在被修饰之前（有些单个过去分词作宾语时,也可放在被修饰词之后）,如:分词短语作定语一般放在被修饰词之后,有时可用定语从句代替。单个分词作前置定语表示被修饰词所发出的动作,即分词动作的逻辑主语是它修饰的词。如:?TheexcitingnewsthatChineseathleteswonover20goldmedalsinSydney2000OlympicGamesinspiredallofus.（单个现在分词作前置定语,表示被修饰词所发出的动作,即Thenewswasexciting.）?Thebuildinglyingonthewestoftheseacostsome20000000dollars.（现在分词短语作后置定语,相当于一个定语从句thatlies）?现在分词表示主动的动作或正在进行的主动动作,如:boilingwater,therisingsun,developingcountry;过去分词表示被动动作或已完成的动作,如:boiledwater,therisensun,developedcountry。?2.分词作后置定语应注意:?(1)现在分词表示的动作:?①一个正在进行的动作,如:?Canyouseetheshipdisappearing(thatisdisappearing)inthedistance??②表示将来的动作,如:?Canyoutellmethenumberofpeoplecomingtotheparty(whowillcometotheparty)??③表示某个经常性的动作或状态,如;?Thegirllookingafter(wholooksafter)Harry’schildrengets200dollarsaweek.?(2)过去分词表示的动作:?①发生在谓语动词的动作之前,如:?Isthisthebookwritten(thatwaswritten)byHenryJames??②与句中谓语动词是相应的经常性的动作,如:?Hewasthenaprofessorrespected(thatwasrespected)byalltheteachersandstudentsofthecollege.?③being+过去分词结构表示动作正在进行,如:?The65-storeyedbuildingbeingbuilt(thatisbeingbuilt)willberunbyaUScompany.?正在建设的那座65层大楼将由一家美国公司经营。?④tobe+过去分词结构表示一个将来动作,如:?Hewasinvitedtotheconferencetobeheld(thatwillbeheld)inShanghaiinMay2001.?分词前置?Wecanseetherisingsun.我们可以看到东升的旭日。?Heisaretiredworker.他是位退休的工人。?分词后置(i.分词词组;ii.个别分词如given,left;iii.修饰不定代词something等)?Therewasagirlsittingthere.有个女孩坐在那里。?Thisisthequestiongiven.这是所给的问题。?Thereisnothinginteresting.没有有趣的东西。?过去分词作定语?与其修饰的词是被动关系,相当于一个被动语态的定语从句。?Mostofthepeopleinvitedtothepartywerefamousscientists.?MostoftheartistsinvitedtothepartywerefromSouthAfrica.?

典型例题1)Thefirsttextbook__________forteachingEnglishasaforeignlanguagecameoutinthe16thcentury.A.havewrittenB.tobewrittenC.beingwrittenD.written解析：书与写作是被动关系,应用过去分词作定语表被动,相当于定语从句whichiswritten。?答案：D?2）What’sthelanguage__________inGermany??A.speakingB.spokenC.bespokenD.tospeak解析：主语language与谓语动词之间有被动的含义。spoken是动词speak的过去分词形式,在句中作定语,修饰主语language,spoken与language有被动关系。该句可以理解为:What’sthelanguage(whichis)spokeninGerman??答案：B?3.作表语的分词通常看作形容词来用。现在分词表示主语的性质,而且主语多为物;过去分词表示主语的感受或状态,主语多为人。如:?(1)Thestoryisinteresting.故事有趣。?Weareinterestedincomputers.我们对计算机感兴趣。?(2)Theglassisbroken.玻璃杯破了。?(3)Thewaterisboiled.水是开的。?

两种形式的过去分词在英语中,有些动词有两种过去分词形式,并且它们在用法和意义上不同?1)learned/learnt?两者都可用在完成式中构成谓语,但learned还可作定语“博学的”之意解。而learnt不能。[举例]Wehavelearned/learnt200newwordssincelastterm.?从上学期开始,我们已经学了200个新词了。?ProfessorWangisalearnedman.王教授是个有学问的人。?2)lighted/lit?lighted可用作定语,lit用作表语。?[举例]Thelightedcandlelitthewholeroom.?点燃了的蜡烛照亮了房间。?Thecigaretteisnotlit.烟没点着。?3)hung/hanged?hung意为“悬挂”,hanged意为“绞死,吊死”。?[举例]Afamouspaintingishungonthewall.墙上挂着一幅名画。?Hewashangedbyhisenemy.他是被敌人绞死的。?4)hid/hidden?hid用于完成时,hidden可作表语和定语。?[举例]Thesunishidden.?太阳被云遮住了。?Theremustbesomeonehiddeninthecupboard.?一定有人藏在柜子里。?Wherehaveyouhidmybook??你把我的书藏在哪儿了？?5)struck/stricken?struck用于完成时构成谓语,stricken用作定语,还可表示“受到打击”。?[举例]Theclockhasstruckthree.?时钟已敲响了三点。?Therescueteamsracedtothestrickenship.?救援队立刻前往抢救遇难船只。?6)born/borne?born既可用作表语,又可用作定语,borne用于完成时构成谓语。?[举例]HewasborninJapanin1973.?他于1973年出生于日本。?Sheisabornsinger.?她是个天生的歌唱家。?Shehasbornetwoboys.?她已经生了两个男孩。?7)burned/burnt?burned强调燃烧的动作,burnt强调状态或结果,还可用作定语。?[举例]Alotofpeoplewereburnedinthebigfire.?很多人在那场大火中被烧死了。?Oilisburntincars.汽车用汽油作燃料。?Theburntpeoplearebeingtreatedinhospital.?烧伤的人们正在住院接受治疗。?8)sunk/sunken?sunk用作表语,sunken用作定语。?[举例]TheshipofTitanicwassunkforever.?泰坦尼克永久地沉没了。?Thesunkenboatcouldneverbefound.?那艘沉船再也没有找到。?9)melted/molten?melted用作表语,molten用作定语。?[举例]Theiceintheriverismelted.?河里的冰融化了。?Themoltensteellookslikewater.?熔化了的钢看上去像水一样。?
