Question

The door was pushed open,who should come in but the woman they were talking about.

求大神帮我分析一下后面句子的语法，有那个but有什么用处，should应该怎么解释？

Answer 1

为你解答：

The door was pushed open, who should come in but the woman they were talking about.
门被推开了，进来的人竟然就是他们在谈论的那个女人。

后面句子的语序可以调整为：who but the woman (that) they were talking about should come in

主语：the woman
谓语：should come in
定语从句：they were talking about （修饰the woman）
who but...表示强调，类似于 nothing but
should 表示意料之外

不懂请追问，满意请采纳。谢谢！
