修饰物体时关系代词that和which的区分使用that的情况:1
当先行词是nothing,something,anything,all,each等不定代词时
Doyouhaveanythingthatisimportanttotellme
当先行词被all,any,some,no,not,every,each等修饰时
Ihavesomebooksthatareverygood
当先行词被形容词最高级、序数词所修饰时
ThisisthefirstbookthatIboughtmyself
ThebiggestbirdthatIcaughtisthisbird
主句是以which或who开头的特殊疑问句时e
Whichisthebikethatyoulost
Whoisthewomanthatwaspraisedatthemeeting
当先行词在从句和主句中都作表语时,无论先行词是人还是物
Chinaisnolongerthecountrythatshewas
如有两个定语从句,其中一个已用which引导,另一个宜用that
Edisonbuiltupafactorywhichproducedthingsthathadneverbeenseenbefore
在therebe句型中,只用that
Heaskedforthelatestbook(that)thereisonthesubject
当先行词被thevery,thelast,thenext,theonly等词修饰时
ThisistheverybookthatIlostyesterday
当先行词又有人又有物时
Iwon’tforgetthethingsandthepersonsthatIsaw
只能使用which的情况
1、非限制性定语从句
