_____tomorrow morning,she would reach Beijing by this Sunday.

题目

_____tomorrow morning,she would reach Beijing by this Sunday.
请问这里为什么要用Were she to live而不用would she live?

答案

这是一个虚拟语气的假设句.
__Were she to live__tomorrow morning,she would reach Beijing by this Sunday.
意思是她不可能办到.
would she live 是问句形式,不合此句语义.
