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.)
