定语从句中的关系词为关系副词时,从句有没有介词?
2个回答
一般来说,关系副词和介词不会连用.
但是,对于介词 from,可能出现一些特殊情况.如：
Beijing is the place where he comes from.
（正如可以说：Where does he come from?或 Where is he from?）
The school library is the place where he got the book from.
（这一句中from也可以不用.）
His head soon appeared out of the second-storey windows,from where he could see nothing but trees.(这一句where 也可改用which.)
（比较：His head soon appeared out of the second-storey windows.From there he could see nothing but trees.）
