onwhichIfirstmethim.(表示具体某一天用介词on)(2)二动：根据从句谓语动词习惯搭配e.g.Thisisn'tthebook

aboutwhichtheteachertalkedinclass.(talkabout谈论)Thethingsofwhichtheyareproudweretheirgoldwatchandbeautifullooking.(3)三意义:根据从句表达的意义e.g.Thecolorlessgas

withoutwhichwecannotliveiscalledoxygen.(离开介词用without).特殊：1.介词前有时加名词、数词等，构成“名词/数词/不定代词＋ofwhich/whom”结构，在定语从句中作主语e.g.Englishisalanguagesharedbyseveraldiversecultures,eachofwhichusesitdifferently.英语是一种多元文化共享的语言，每一种文化使用它的方式各不相同。Conclusion关系副词先行词
