这里为什么要用to which,

1个回答

  • 最简单的方法是从

    the extent to which it has become a political liability for the White House.

    的问句开始,

    这个句子的问句是

    To what extent has it become a political liability for the White House?

    句子的倒装形式就是

    the extent to which it has become a political liability for the White House.

    (倒装句 不用 to what ,而必须用 to which .)

    再举两个类似例子:

    In what way is the invention useful?

    倒装形式:

    The way in which the invention is useful is ...

    On what grounds are you justifying this action?

    倒装形式:

    The grounds on which I justify this action are ...

    这是弄清楚短语

    to which,in which,on which 等等

    的用法的唯一方法.
