Unit2 success stories-grammar学案The Relative Clause III. I. 由关系副词引导的定语从句.1. 1. 关系副词: when, where, why2. 2. 用法: 关系副词在定语从句中均不作主语或宾语, 而是作状语1) 1)when指时间, 在从句中作时间状语I still remember the day when we first met. = I still remember the day on which we first met.2) 2)where指地点, 在定语从句中作地点状语Shanghai is the city where I was born.= Shanghai is he city in which I was born.3) 3)why指原因, 在定语从句中作原因状语Do you know the reason why he was absent from school?= Do you know the reason for which he was absent from school?II.

(作宾语)Is this the museum where we saw a film last month? (作状语)This is the reason that he gave us for his behavior. (作宾补)This is the reason why he didnt come to school. (作状语)III. 特殊句型Each time/ every time / the moment / the first time etc. + 从句, 当这一结构表示某个时间时, 可以把这些试件词看成一个整体, 相当于由when引导的状语从句, 因此其后不用关系副词Each time I call on him, he is out. (R) When I call on him, he is out.Each time when I call on him, he is out. (W)
