在复合句中修饰名词或代词的从句叫定语从句,被修饰的名词或代词叫先行词,引导定语从句的词叫关系代词或关系副词,关系代词有that,which,who,whom,whose,as,关系副词有when,where,why
一、关系词的基本用法二、必须用“that”引导的定语从句4、当先行时前有such或thesame修饰时,先行词和关系代词指同一物时
Sheiswearingthesamedressthatsheworeyesterday
5、先行词既有人又有物时,Latertheytalkedofthingsandpersonsthattheyrememberedintheschool
6、当主句是以who或which开始时的特殊疑问句时,Whoistheboythatwonthegoldmedal
7、在同一个句子里,若有两个定语从句,其中一个关系词已用了which,另一个宜用that
Edisonbuiltupafactorywhichproducedthingsthathadneverbeenseenbefore
8、当关系代词在从句中作表语时
(只限于限制性定语从句中)Chinaisnolongerthecountrythatitusedtobe
9、当先行词是集体名词时,多用that,Hewantstojointheteamthatwonthegame
10、that在有些句型中可作为关系副词,且可省略
Idon’tliketheway(that)hetalkstome
Ihavethesamebookasyou(have)
Takeasmanyasyouwant
Hereissobigastoneasnomancanlift
