定语从句why的用法:
关系副词why在定语从句中也是用作状语,表示原因;why引导定语从句时,其先行词只有一个,那就是the reason;在许多情况下why也可以理解为for which。如:
These are the reasons why we do it. 这些就是我们这样做的`理由。
句中的why we do it为修饰the reason的定语从句,关系副词why在此相当于for which。
Do you know the reason why she doesn’t like me? 你知道她不喜欢我的原因吗?
句中的why she doesn’t like me为修饰the reason的定语从句,关系副词why在此相当于for which。
why是一个比较特殊的关系副词,它引导定语从句时,除可换成for which外,有时也可换成that,甚至省略。如:
他失去工作的主要原因是他喝酒。
正:The main reason why he lost his job was that he drank.
正:The main reason for which he lost his job was that he drank.
正:The main reason that he lost his job was that he drank.
正:The main reason he lost his job was that he drank.
