介词+which
eg:this is the book for which I paid 5 yuan(pay…for…“支付”)
定语从句中,关系词做宾语可以省略(介词后面的关系词不可省略)
eg:this is the pen(that)I am looking for
eg:I have many friend(whom)I can ask for help at anytime
表示时间、地点、原因的名词在定语从句中做主语或宾语时,用that/which
eg:He bought the house that/which/不填 I visited yesterday
eg:I still remember the day that/which/不填 is his birthday
当先行词为表示模糊地点或者抽象地点名词时,关系词在从句作地点状语,则用where引导
包含:condition、point、position、case、situation
句型结构:…先行词,数词/名词/代词 of which/whom
eg:In this movie,there are many actors,2 of whom are famous
eg:they are two modles left,one of which is almost finished
whose指物时,可用…of which(=of which …)代替。(其中when、where、why也有此类用法,介词取决于时间、地点前的介词,原因介词是for)
when/where/why=介词+which
指时间状语when=at/on/in/during+which
指地点状语where=at/on/in+which
先行词:village、park、place、room、house等
定语从句只能用that的情况
极端修饰:序数词、最高级、the very、the only、the right、the same
不避人物
主语是who/which引导的特殊疑问句时,避免重复
定语从句只能用which的情况
非限制性定语从句(主从句有逗号隔开),指物用which,指人用who
指物且在介词之后,指物用which,指人用whom
