關系代詞which有何用法

關系代詞which在定語從句中通常只用于指事物，不用于指人。它在句子中主要用作主語或賓語。如：

She was not on the train which arrived just now. 她不在剛才到達的那列火車上。(which在定語從句中用作主語)

I’ve found the car keys which you were looking for. 你要找的汽車鑰匙我找著了。(which在定語從句中用作賓語)

關系代詞which有時還可在定語從句中用作定語。如：

He advised me to hide behind the door, which advice I took at once. 他勸我躲在門后，我立即照他的話做了。

注意，關系代詞which原則上只指物，不指人。但是，有時指的不是具體的某人，而是指某人的職業、身份、地位、職務、品質、特征等，此時要用which 而不用who。如：

He talked like a scholar, which he was not. 他說起話來像個學者，其實他沒什么學問。

She talked like a native, which she hardly was. 她說起話來像是個本地人，其實她不見得是。

They accused him of being a traitor, which he was. 他們指控他是叛徒，他真是叛徒。
