定语从句初中英语 17页

一、定义：在复合句中，修饰某一名逊词的从句叫做定语从句。女口：1)Themanwholivesnexttousisapoliceman.2)YoumustdoeverythingthatTdo.上面两句中的man和everything是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。*引导定语从句的词有关系代词that,which,who(宾格whom,所有格whoso)和关系副词where,when、why*关系词常有三个作用：1、引导定语从句2、代替先行词3、在定语从句中担当一个成分二、关系代词引导的定语从句*l.who指人，在从句中做主语(1)TheboyswhoareplayingfootballarefromClassOne.(2)YesterdayThelpedanoldmanwholosthisway.*2.whom指人，在定语从句中充当宾语，常可省略。(1)Mr.Liuistheperson(whom)youtalkedabout.注意：关系代词whom在口语和非正式语体中常用who代替，可省略。(2)Theman(who/whom)youmetjustnowismyfriend.*3.which指物，在定语从句中做主语或者宾语，做宾语时可省略(1)Footballisagamewhichislikedbymostboys.(which在句子中做主语)(2)Thisisthepen(which)heboughtyesterday.(which在句了屮做宾语)*4.that指人时,相当于who或者whom；指物时,相当于which,在定语从句中做主语或者宾语，做宾语吋可省略。(1)Thepeoplethat/whocometovisitthecityareallhere.(在句子中做主语)(2)Whereistheman(that/whom)Isawthismorning?(在彳ij了屮做宾语)*5.whose通常指人，也可指物，在定语从句中做定语(1)Hehasafriendwhosefatherisadoctor.(2)T1ivedinahousewhoseroofhasfallenin.whose指物时，常用以卜•结构來代替(3)Theclassroomwhosedoorisbrokenwillsoonberepaired.=Theclassroomthedoorofwhichisbrokenwillsoonberepaired.(4)Doyoulikethebookwhosecolorisyellow?=Doyoulikethebookthecolorofwhichisyellow?*具体使用时还要注意下列问题：1、只能使用that,不用which的情况:*1)当先行词是:all,any,anything,everything,nothing或被它们修饰时。TsthereanythingthatIcandoforyou?有什么可以为你做的吗?Allthatcanbedonemustbedone.凡是能做的都必须做。*2)当先行词被形容词的最高级或序数词修饰时。例如：Thatisoneofthemostinterestingbooksthataresoldinthebookshop.那是这家书店出售的最冇趣的书Z—。Thefirstthingthatweshoulddoistogetsomefood.我们该做的第一件事是弄点吃的。*3)当先行词有：theonly,thevery,thesame,thelast等修饰时。例如：Mynecklaceisnottheonlythingthat'smissing・\n我的项链不仅是丢掉的东西。*4）当主句以who或which开头时，定语从句中引导词用that,不用which或who,以避免重复。例如：Whoisthegirlthatiswearingaredcoat?正穿一件红色外套的女孩子是谁？*5）当先行词既有人又有物时，用that。例如：Thewriterandhisnovelthatyouhavejusttalkedaboutarereallywellknown.伤〈刚才谈起的那位作家以及他的小说确实很著名。2、只用which不用that的情况：*1）关系代词前有介词时；e.g.ThisistheroominwhichLuXunlived.*2）非限定性定语从句中；作宾语用的关系代词也不能省略。e.g.Thatnccklace,whichyougavemeasapresent,waslostyesterday.Hehasadaughter,whoworksinahospital.*3）先行词本身是that时；e.g・TheclockisthatwhichtelIsthetime非限定性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从旬拿掉示其他部分仍可成立。CharlesSmith,whowasmyformerteacher,retiredlastyear.査理史密斯去年退休了，他曾经是我的老师。（非限）Thereissomebodyherewhowantstospeaktoyou这里有人要和你说话（限制性）*4）which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种从句小，which可以作主语，也可以作宾语或表语，多数情况下意思是少andthis相似，并可以指人。Hedidverywel1inthecompetition,whichmadehisparentsveryhappy.*关系代词whom,which在定语从句中作介词宾语时，可以和介词一起放于先行词与定语从旬之间，有时为了关系紧凑也可以将whom与which与先行词紧挨着书写，而将介词置于定语从句的后面，Thatwastheroominwhichwehadlivedfortenyears.=Thatwastheroomwhichwehad1ivedinfortenyears.*像listento,lookat,takecareof等固定短语动词,在定语从句中一般不宜将介词与动词分开。例如:Thisistheboywhomshehastakencareof.三、关系副词引导的定语从句*1、when：当主句屮的先行词（即主句中被后面定语从句修饰的词）是表示时间意义的名词时，它只能作定语从句的时间状语，放在定语从句句首。如果定语从句的引导词是作该定语从句的主语或宾语，则要改用关系代词that或which来引导。例如：I'11neverforgetthetimewhenweworkedonthefarm.HearrivedinBeijingonthedaywhonIleft.Thedayswhenweusedforeignoilaregone.我们用洋油的日子—去不复返了。I'llneverforgetthedaywhenIwasborn.（=T，11neverforgetmybirthday.）我永远不会忘记我出牛的H子。\nIthappenedinNovemberwhentheweatherwaswetandcold.这事发生在天气乂湿又冷的十一月。Theday（that）Ialwaysrememberinal1mylifeismybirthday.我一^■牛中最难忘的日子是我的生日。（that作定语从句"thatIalwaysrememberinallmylife"的宾语，that可以省略）*2.where：当主句中的先行词是表示地点意义的名词时，它只能作其所在的定语从句的地点状语，放在定语从句的句首。如果定语从句的引导词作该定语从句的主语或宾语吋,也要改用关系代词that或which來引导。例如：ThefactorywherehisfatherworksisintheeastofthecityThisistheroomwhere（=inwhich）Ilivedlastyear.这就是我去年住过的房间。Isthistheclassroomwhere（=inwhich）theoldworkerisgoingtomake/giveusareport?这就是那位老工人要给我们做报告的教室吗？Let'slookforaplacewherewecanswim.咱们找一个可以游泳的地方吧。Thebuildingthatisbeingbu订tovertherewillbeanewhospital.正在那边建的楼房将是一家新医院。（引导词that作定语从句"thatisbeingbuiltoverthere"的主语）Thatisthefactory（that）theyvisitedlastmonth.那就是他们上个月参观过的工厂。（引导词that作定语从句"（that）theyvisitedlastmonth*的宾语，that可以省略）*注意：不要以为在时间名词后就一定用关系副词when,在地点名词后就一定用关系副词where,在表示原因的thereason就•定用关系副诃why。到底选用关系副诃还是关系代词，关键是看它们在从句中是用作状语（用关系副词）还是用作主语或宾语（用关系代词）。如：Don'tforgetthetime（that）I'vetoldyou.不要忘记我告诉你的时间。（that用作told的宾语）1911neverforgetthedayswhenIworkedwithyou.我永远不会忘记我与你共事的日了。（when用作状语）lieworksinafactorythat/whichmakesradioparts.他在一•家制造无线电零件的工厂工作。（that/which在从创屮用作主语，且不能省略）Heworksinthefactorywherehisfatherworked.他在他父亲工作过的那家工厂工作。（where作状语）That"sthereason（that/which）heexplainedtous.那就是他向我们解释的理由。（that或which在从句中用作explained的宾语）That'sthereasonwhyshelefthome.那就是她离家出走的原因。（why在从句中作状语）*英语中的关系副词主要是when,where,why三个，不要想当然地将how用作关系副词修饰theway。女II不说Thisisthewayhowhespoke,可改为Thisishowhespoke（how引导的是表语从句）,当然也可说成Thisistheway（that/inwhich）hespoke.（其中的that/inwhich可省略）*另外，when和where可引导限制性和非限制性定语从句，而why则只用于引导限制性定语从句，不用于引导非限制性定语从句。\nSundayisahoiiday,whenpeopledonotgotowork・星期天是假日，（这天）人们不上班。Hetookusintotheclassroom,wheretherewereonlyafewstudents.他把我们带进教室，那儿只有少数几个学生。*在定语从句的使用中，oneof后面的名词是复数，这个复数名词制约示面的定语从句的谓语动词，用复数；而在oneof前面有the或theonly时，后面引导的定语从句小的谓语动词则用单数形式。Heistheonlyoneofthestudentswhoiselected?Jasperisoneofthosepeoplewhoknowabouttheaccident•定语从句练习一、请分析一卜•定语从句：（请划出定语从句，并标出先行词）\n1.CheckthewaysyoustudyforanEnglishtest・2・AnotherthingthatIfoundverydifficultwasEnglishgrammar.3.Youcouldn'tunder
