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. II.      容易用错的关系副词和关系代词先行词是时间, 地点, 原因的名词, 定语从句不一定就由关系副词引导We will never forget the day that we spent together.(作宾语)We will never forget the day when we spent the holiday together.(作状语)Is this the museum that we visited last month? (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 didn’t 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)。
