Thepenwhichmyunclegavemeismissing. Helivesinahousewhosewindowsfacesouth. Thefactorywheremyfatherworksisintheeastofthecity. Perhapsthedaywillewhenpeoplewillbeabletobreathecleanairincities. Ⅱ.关系代词 1.先行词是人,作主语,关系代词用who,that eg.Heisaman()neverleavestoday’sworktilltomorrow. Theboy()isstandingthereismycousin. 2.先行词是人,作宾语,关系代词用whom,who,that, eg.Hereistheman()you’vebeenexpectingtomeet. Theman()youmetyesterdayisMr.Smith. 3.先行词是物,作主语,关系代词用which,that eg.Thetrain()hasjustleftisforGuangzhou. Childrenliketoreadbooks()havewonderfulpictures. 4.先行词是物,作宾语,关系代词用which,that,或省略 eg.Thebook()youborrowedyesterdayisreallyinteresting. Thepen()myunclegavemeismissing. 5.先行词是人、物,作定语,关系代词用whose eg.Heistheprofessor()namewasJackson. China,()populationisthelargestintheworld,isdevelopingveryfast. Ⅲ.关系副词 1.先行词是表示时间的名词,在定从中作时间状语,关系代词用when eg.Ican’trememberthedate()hewentabroad. I’llneverettheday()Ijoinedthearmy. 2.先行词是表示地点的名词,在定从中作地点状语,关系代词用where;其中注意表示抽象概念的地点名词,如,situation、stage、degree、point等表示方面或程度时,也需用where eg.Thisisthevillage()UncleWangoncelived. Theyhavereachedthepoint()theyhavetoseparatewitheachother. He’sgothimselfintoadangeroussituation()heislikelytolosecontrolovertheplane. 3.先行词是reason,在定从中作原因状语,关系代词用why eg.Idon’tknowthereason()hewaslate. Noneofusknowthereason()Tomwasabsentfromthemeeting. 4.引导定语从句的关系副词也可以用“适当介词+which”来代替。
eg.October1,1949wasthedaywhen(=)thePeople’sRepublicofChinawasfounded. Thisisthefactorywhere(=)weworkedayearago. Idon’tbelievethereasonwhy(=)hewaslateforschool. Ⅳ.关系代词that&which的区别: ⒈只用that的情况 ①先行词为all,everything,anything,nothing,little,much等不定代词时 eg.Thereisnothing()canpreventhimfromdoingit. ②先行词被any,only,few,no,very,little等修饰时 eg.Thisistheverybook()I’mlookingfor. ③先行词被形容词最高级或序数词修饰时 eg.Thefirstplace()theyvisitedinGuilinwasElephantTrunkHill. Thisisthebestfilm()Ihaveeverseen. ④先行词既有人又有物时。
eg.Hetalkedaboutthingsandpersons()theyrememberedintheschool. ⑤先行词被theonly,thevery修饰时 eg.Mr.Smithistheonlyforeigner()heknows. ⑥句中已有who或which,为了避免重复时 eg.Whoistheman()isstandingbesideTom? ⒉不能用that的情况: ①引导非限制性定语从句; eg.Hehadfailedinthemathsexam,()madehisfatherveryangry. ②介词+关系代词 eg.Thisistheroomin()myfatherlivedlastyear. Ⅴ.as引导定语从句时的用法(as相当于that&which) ①as引导限制性定语从句通常用于thesame…as,such…as结构中 eg.Thisisthesamebook()Ilentyou. Suchmachines()areusedinourworkshoparemadeinChina. ②as引导非限制性定语从句既可放在主句之前,也可放在主句之后,位置灵活,用来修饰整个句子。
通常用下列句型:asisknowntoall,asissaid,asisreported,asisannounced,asweallknow,asIexpect等 eg.()Iexpected,hegotthefirstplaceagaininthismid-termexamination. Taiwan,()weallknow,belongstoChina. Ⅵ.限制性定语从句和非限制性定语从句的主要区别: 限制性定语从句:一般紧跟在先行词后面,不用逗号把从句与先行词分隔开来使先行词的意思十分明确,成为特定的人或物,是句子中不可缺少的成分,少了它句子就会失去意义不能成立,或意思不清楚,不能说明问题通常译为定语 非限制性定语从句:通常由逗号与句子其他成分隔开只是对先行词作进一步的说明,没有它句子仍能成立,意思仍很清楚通常译为并列的句子 eg.Iwastheonlypersoninouroffice()wasinvited.(去掉定语从句,意思就不完整) Tom’sfather,()isoversixty,stillworksharddayandnight.(整个句子可分成两句来翻译) Ⅶ.分隔定语从句 即先行词与关系代词、副词之间被介词短语,同位语,谓语等分隔开来。
此种定语从句,在选择关系词时,要注意找准先行词 eg.Thereisanexpressioninhiseyes()Ican’tunderstand. Iwastheonlypersoninmyoffice()wasinvitedtotheimportantball. IsuggestyouchoosesomeoneIthink()isverykindandfriendly. 选择填空: 1.ItwasApril29,20XX PrinceWilliamandKateMiddletonwalkedintothepalacehalloftheweddingceremony.
