一 快捷識記
限制性定語從句和主句之間不用逗號分開，修飾主句中的某一個(gè)名詞或名詞詞組或代詞；非限制性定語從句常用逗號和主句隔開，可以修飾主句中的某一個(gè)詞，也可修飾整個(gè)句子。非限制性定語從句不能用that引導(dǎo)，引導(dǎo)非限制性定語從句的關(guān)系詞不能省略。
非限制性定語從句例：Li Pings father, who works in a factory, is an engineer./He tore up my photo, which made me very angry.(which指代主句內(nèi)容，因前后兩句是因果關(guān)系，此時(shí)which不可換為as。)
He is good at physics, as is known to us all.＝As is known to us all, he is good at physics.(as指代主句內(nèi)容，在as is known/believed, as we all know/believe這類結(jié)構(gòu)中as不可換為which)
