weweretalkingaboutthepersonsandthingsthatwerememberedinourschool 先行词前有theonly thevery theright thesame等修饰时 要用that itistheveryskirtthatsuitsmewell 2 宜用which引导的定语从句当定语从句的介词提前时 要用which

istillrememberthetimewhenifirstbecameacollegestudent doyouknowthedatewhenlincolnwasborn 注 when时常可以省略 特别是在某些句型和某些时间状语中 例如 eachtimehecame hedidhisbesttohelpus buthelpneverstoppedcomingfromthedayshefellill 2 where指地点 在从句中作地点状语 它的先行词通常有 place spot street house room city town country等 如 thisisthehotelwheretheyarestaying iforgetthehousewherethesmithslived 注 where有时也可以省略 如 thisistheplace where wemetyesterday 3 why指原因或理由 它的先行词只有reason thatisthereasonwhyheisleavingsosoon 注 why时常也可以省略 如 thatistherealreasonhedidit 使用关系副词应注意下列几点 1 这三个关系副词在意义上都相当于一定的介词 which结构 when on in at during which where in at on which why forwhich 如 iwasinbeijingonthedaywhen onwhich hearrived theofficewhere inwhich heworksisonthethirdfloor thisisthechiefreasonwhy forwhich wedidit 2 当先行词是表时间的time day等和表地点的place house等时 一定要注意分析从句的结构 如果缺少主语或宾语时 关系词应该用which或that 缺少时间状语或地点状语时 才能用when或where 试比较 i llneverforgetthedaywhenmyhometownwasliberated i llneverforgetthedayswhich thatwespenttogetherlastsummer hisfatherworksinafactorywhereradiopartsaremade hisfatherworksinafactorywhich thatmakesradioparts 温馨提示 when和where既可以引导限制性定语从句 也可以引导非限制性定语从句 而why只能引导限制性定语从句 1 i llneverforgetthedays weworkedtogether 2 i llneverforgetthedays wespenttogether 3 iwenttotheplaceiworkedtenyearsago 4 iwenttotheplace ivisitedtenyearsago 5 thisisthereason hewaslate 6 thisisthereason
