1、定语从句专讲学习定语从句的关键是如何选择关联词。关联词在句中作状语就应使用关系副词.(where,when,why等。)否则使用关系代词(who,whom,whose,which,that等。)二、由who,whom,whose引导的定语从句:(who作主语,whom作宾语,whose用作定语,同时whose还可以指物,相当于ofwhich。)e.g.:Thisisthedoctorwhosavedthebaby'slife.Heisthestudentwhomtheteacherpraisedatthemeeting.一、在复句
2、中修饰名词或代词的从句叫做定语从句。需要学习和掌握的定语从句有以下三种:由关系代词或关系副词引导的定语从句。由介词+which引导的定语从句。非限制性定语从句。1.Iknowthegirlwhosemotherdiedayearago.2.Haveyouseenthenotebookwhosecoverisblack?三、由which引导的定语从句:(which在从句中作主语或谓语动词的宾语。)E.g.1.Thisisthestorewhichopensallnight.2.Thisisthepenwhichmybrotherb
3、oughtforme.3.IsthistheHouseinwhichLuXunoncelived?(orIsthisthehousewhichLuXunoncelivedin?)4.Thisisthemagazinewhichyouarelookingfor.Notes:which,whom在从句中作介词的宾语时,介词一般可置关系代词之前或放在从句原来的位置。但在含有介词的动词固定短语中介词只能放在原来的位置上,而不能放在which之前,如例4则不能改为Thisisthemagazineforwhichyouarelooking
4、.3.Helivesinaroomwhosewindowopenstothesouth.四由that引导的定语从句,可以指人或物,代替who,whom,which.1.在定语从句中that在从句中作主语、宾语,但不能放在介词后作介词宾语:、E.g.:1.Thisisthephoto(that/which)ItookinBeijinglastyear.2.Thisistheman(that/who)livesnextdoor.3.Isthistheprofessorthatyoutalkedaboutyesterday?(a
5、bout不能放在that前面。)但下列情况只能用that。1.序数词或最高级形容词修饰先行词时用that。E.g.:1.ThisisoneofthebestnovelsthatIhaveeverread.2.ThefirstEnglishsongthatIlearnedwasABCsong.2.Allmuch,everything,nothing,something,anything作先行词时用that.(但先行词是everybody,everyone时应用who,one指人时也用who。)E.g.:1.Everythingtha

7、ehasreceivedfromhim.3.Thisistheverymuseumthatwevisitedforthefirsttime.4.that可以用来引导限制性定语从句,当它在从句中作介宾时,介词应后移。E.g.:Thisisthegoodstudentthattheteacherstalkedaboutjustnow.5.先行词既指人又指物的并列名词时,用that.E.g.:Mymotherandheroldfriendstalkedofthethingsandpersonsthattheyremembered
8、intheschool.非限制性定语从句:限制性定语从句对先行词起限制作用,而非限制性定语从句是对概念清楚的先行词加以追加阐述或补充说明1.非限制性定语从句一般用which/who引导而不用that或what引导,作宾语的关系代词不能省略,
