which(代词)引导非限制性定语从句。
下边详细讲解。
(一)as(代词)引导限制性定语从句
1. 当先行词是“such/the same+名词”时,用as引导定语从句。即,such+n.+as(代词),the same +n.+as(代词)。
例句(as指代such+n.,作主语/宾语/表语)
●We invited all such people as were likely to come.
(as在从句中作主语。as=all such people,即,All such people were likely to come.)
●I have never heard such stories as he tells. 我从未听说过他讲的这类故事。
(as在从句中作宾语。as=such stories,即,He tells such stories。)
●I’ve never seen such a fool as he is.
(as在从句中作表语。as= such a fool,即,He is such a fool.)。
例句(as指代the same +n.,作主语/宾语/表语)
●Is this the same mosquito as bit you just now?(as作主语。The same mosquito (=as) bit you.)
●This is the same knife as I lost yesterday.(as作宾语。I lost the same knife (=as) yesterday.)
●She is just the same person as she used to be.(as作表语。She used to be the same person (=as).)
