如何区分关系代词和关系副词引导的定语从句用法依据根据从句的谓语动词是及物动词，后面若无宾语，用关系代词；是不及物动词则用关系副词根据先行词在从句中所作的成分把先行词代入定语从句中，若作主语或宾语用关系代词；作状语则用关系副词定语从句的引导词用关系代词还是关系副词可以用以下两种方式判断：1.when相当于“at/in/on/during等+which”Iremembertheday________________

IsettledinChina.2.where

相当于“in/at/on等+which”Thehouse________________Marklivedisnowalibrary.3.why

相当于“for+which”Isthatthereason________

shesuddenlychangedhermind?5.“介词+关系代词”引导的定语从句1.关系副词when，where，why引导定语从句时，也可用“介词+which”代替关系副词。when(=onwhich)where(=inwhich)why(=forwhich)1.Thisisthestudent__________

Iboughtabook.2.Thisistheship_________

IwenttoShanghai.2.在“介词+关系代词”引导的定语从句中，关系代词只能用which或whom,不可用that/who。先行词指物时用which，先行词指人时用whom。forwhombywhich(二)选用介词的依据1.根据先行词的搭配，,从句中的动词、形容词等的搭配(即固定短语)。(1)YesterdaywevisitedtheWestLake___________Hangzhouisfamous.(2)Heisthestudent___________weshouldlearn.(3)Irememberthedays____________Ilivedhere.(4)Ican’tremembertheage_________

hewontheprize.2.根据句子的意思来选择。(5)Thisisthepilot_________mybrotherhasworkedfortenyears.(6)Thisisthepilot___________mysonwassaved.forwhichfromwhomduringwhichatwhichwithwhombywhom3.“名词，不定代词或数词+of+which(指物)/whom(指人)”在定语从句中作主语，说明整体中的一部分。1.Chinahaslotsofislands,____________
