小升初定语从句讲解及习题
定语从句
一、定语从句及相关术语
1•定语从句:
修饰一个名词或代词的从句称为定语从句,一般紧跟在它所修饰的先行词后面。
2•关系词:
引导定语从句的关联词成为关系词
关系词有关系代词和关系副词。
关系代词有that,which,who,whom,whose,as等;
关系副词有where,when,why等。
关系词常有3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
1.who指人,在从句中做主语

2.whom指人,在定语从句中充当宾语,常可省略。

(6)Whereisthemanthat/whomIsawthismorning?
5.whose通常指人,也可指物,在定语从句中做定语.对主句先行词的所属性进行修饰的。

(5)Doyoulikethebookwhosecoverisyellow?
(6)Doyoulikethebookthecolorofwhichisyellow?
*三.介词+关系代词引导的定语从句
关系代词在定语从句中做介词宾语时,从句常由介词+关系代词引导
(1)Theschool(that/which)heoncestudiedinisveryfamous.
(2)Theschoolinwhichheoncestudiedisveryfamous.
(3)TomorrowIwillbringhereamagazine(that/which)youaskedfor.

lookfor,lookafter,takecareof等

(2)ThisisthewatchforwhichIamlooking.(F)
2.若介词放在关系代词前,关系代词指人时用whom,不可用who或者that;指物时用which,不能用that;关系代词是所有格时用whose

(2)Themanwho/thatyoutalkedwithismyfriend.(F)

要注意区分以下几个句子的不同

(他还有其他的哥哥)
(2)Hisbrother,whoisnowadoctor,alwaysencourageshimtogotocollege.他的哥哥是当医生的,常鼓励他要考上大学。
(他只有一个哥哥)
难点分析
(一)限制性定语从句只能用that的几种情况
1.当先行词是anything,everything,nothing(something除外),few,all,none,little,some等代词时,或者是由every,any,all,some,no,little,few,much等修饰时
(1)HaveyoutakendowneverythingthatMr.Lihassaid?
(2)Thereseemstobenothingthatseemsimpossibleforhimintheworld.
(3)Allthatcanbedonehasbeendone.
(4)ThereislittlethatIcandoforyou.
注意:
当先行词指人时,偶尔也可以用who
(4)Anymanthat/.whohasasenseofdutywon'tdosuchathing.
2.当先行词被序数词修饰
(1)ThefirstplacethattheyvisitedinLondonwastheBigBen.
3.当先行词被形容词最高级修饰时
(1)ThisisthebestfilmthatIhaveseen.
4.当形容词被thevery,theonly修饰时
(1)ThisistheverydictionarythatIwanttobuy,
(2)Afterthefireinhishouse,theoldcaristheonlythingthatheowned.当先行词指人时,偶尔也可以用who
(3)WangHuaistheonlypersoninourschoolwhowillattendthemeeting
5.当先行词前面有who,which等疑问代词时
(1)Whoisthemanthatisstandingthere?
(2)WhichistheT-shirtthatfitsmemost?
6.当先行词既有人,也有动物或者物体时
(1)Canyourememberthescientistandhistheorythatwehavelearned?
(二)关系代词as和which引导的定语从句
as和which引导非限制性定语从句,有相同之处也有不同之处。
具体情况是:
1.As和which都可以在定语从句中做主语或者宾语,代表前面整个句子。
(1)Hemarriedher,as/whichwasnatural.
(2)Hewashonest,as/whichwecansee.
2.as引导非限制性定语从句,可放在主句之前,或者主句之后,甚至可以切割一个主句;
which引导的非限制性定语从句只能放在主句之后。
另外,as有“正如”,正像””的意思
(1)Asisknowntoall,Chinaisadevelopingcountry.
(2)Heisfromthesouth,aswecanseefromhisaccent.
(3)John,asyouknow,isafamouswriter.
(4)HehasbeentoParismorethanseveraltimes,whichIdon'tbelieve.
注意:
当主句和从句存在逻辑上的因果关系时,常用which
(5)Tomwasalwayslateforschool,whichmadehisteacherangry.
3.当先行次受such,thesame修饰时,常用as
(1)Ihaveneverheardsuchastoryashetells.
(2)Heisnotsuchafoolashelooks.
(3)ThisisthesamebookasIlostlastweek.
注意:
当先行次由thesame修饰时,偶尔也用that引导定语从句,但是和由as所引导的定语从句意思不同
(4)SheworethesamedressthatsheworeatMary'swedding.她穿着她在Mary婚礼上穿过的一条裙子。
(5)Sheworethesamedressasheryoungsisterwore.她穿着和她妹妹所穿的一样的裙子。
(三)以theway为先行词的定语从句通常由inwhich,that引导,而且通常可以省略。
(1)Thewayinwhich/that/./heansweredthequestionwassurprising.
(四)but有时也可以做关系词引导定语从句
(1)Thereareveryfewbutunderstandhisidea.(but=whodon't)
(五)区分定语从句和同位语从句1.定语从句修饰先行词,它和先行词是修饰关系;同位语从句说明先行词的具体内容,是补充说明的关系
(1)TheplanethathasjusttakenoffisforLondon.定语从句
(2)Thefactthathehasbeendeadisclear.同位于从句2.定语从句由关系代词或者关系副词引导,关系词在句中充当成分,有时可以省略;同位语从句主要由that引导,在句中一般不做成分;句子也可以由when,where,how,why,whether,what等词引导,充当成分
(1)Thenewshetoldmeistrue.
(2)Thenewsthathehasjustdiedistrue.
(3)Theproblemthatwearefacingnowishowwecancollectsomuchmoney.定语
(4)Theproblemhowwecancollectsomuchmoneyisdifficulttosolve.
3.同位语从句和先行词一般可以用be动词发展成一个完整的句子,而定语从句不可以
(1)Theideathatwecouldasktheteacherforadviceiswonderful.
(2)Theideawasthatwecouldasktheteacherforadvice.
(3)Thefactthattheearthmovesaroundtheearthisknowntoall.同位语
(4)Thefactisthattheearthmovesaroundtheearth.
介词短语+先行词的定语从句
1.关系代词whose,引导定语从句时,既可指人,又可指物,在从句中只能作定语;
ofwhom只能指人;ofwhich只能指物,有时whose可以与ofwhom禾口ofwhich互
换使用•
女口:
ThegirlwhosehairisgoldenisfromEngland.
头发金色的那个女孩是英国人.
Thehousewhosedoorsaregreenisanofficebuilding.
门是绿色的那座房子是办公楼.
2."介词+whose+名词"引导定语从句

Ilovemymotherland,forwhosegoodfutureIwillworkhard.
我爱我的祖国,为了她美好的未来我要努力工作J
