2.关系副词可以替换为“介词+which(代词)”。即,when/where/why(副词)=介词+which(代词)。(注意:只有在定语从句中,when/where/why可以替换为“介词+which”,在名词性从句和状语从句中不能替换。) ●I remember the day when /on which the heat wave started. ●This is the place where /in which we used to live. ●High taxation is the main reason why /for which governments fall. 3.当先行词是抽象地点或模糊时间,引导词常用where/when。 ①表示抽象地点的先行词(如case, degree, point, stuation)后,一般用where(作状语)引导其定语从句,偶尔也用which(作主语/宾语)引导其定语从句。总之,抽象地点后的引导词,其实仍然是很规则的,只不过大多数都属于该用where的情况而已。 例句(抽象地点后,一般用where,偶尔也用which。) ●I can think of many cases ____you know nothing. (填副词where) ●I can think of many cases ____you know nothing about. (填代词which/that/Ø) ②表示模糊时间的先行词(如,occasion,stay,interval),经常用when(作状语)引导其定语从句。如, ●The occasion when he is misunderstood often happen.他被误解的情况时常发生。 4.当先行词是“表示时间/地点的介词短语”时,引导词用“介词+when/where”。如,“from/to+where”和“since/by+when”。(对比:当先行词是“表示时间/地点的名词”时,引导词常用“介词+which”或when/where。) ●We last saw the man in 1999, since when we have never heard of him. (since when=since in 1999) ●They stood near the north window, from where they could see the whole garden. (from where=from near the north window) 这种结构并非特殊情况,回顾以前学过的特殊疑问句,也有“介词+when/where”的用法。 ●where are you?你在哪里?where are you from?你来自哪里? |
