关系代词在从句中充当主语、宾语、定语（whose,which）。表示人时用who（主格/宾格）,whom（宾格，也就是动词或介词的宾语）,that,whose（所有格）；表示物时用which,that,whose。（注意that和whose既可表人也可表物），另外which可以指代前面整个句子；注意，介词后宾语表人用whom，表物用which，若是表所有格，用whose。特别注意：what不能引导定语从句，只能引导名词性从句。我们来看以下几个例句：Thegirlwho/thatisstandingatthegateisanEnglishteacher.(who或that作从句的主语,表人)That’snotTomwho/thatissittingnexttoJohn.(who或that作从句的主语,表人)=That’snotTom.TomissittingnexttoJohn.Thegirlwhom/who/thatPeteristalkingtoisateacher.(whom作从句宾语,表人)ThegirltowhomPeteristalkingisateacher.(介词可以前置)Thegirltowho/that×Peteristalkingtoisateacher.×（当介词前置时，表人只能用whom）(人)Thegirl(whosemotherisanurse)isateacher.(whose与它所修饰的名词一起构成一个名词短语在从句中担当成分)(物)Thebook(whosecoverismissing)isveryfunny.(不可分割的一部分,指物时可用ofwhich来代替)=Thebook,thecoverofwhichismissing,isveryfunny.Theroom(whosedoorfacessouth)isverybright.(物质所属)=Theroom,thedoorofwhichfacessouth,isverybright.Thebook(which/thatbelongstome)ismissing.（which/that作从句主语，表物）Idon'tlikethenovel(that/whichyouarereading).(that/which作从句动词的宾语，表物)
