_she_yesterday,she would meet the famous singer today.答案为什么是Had't,left?

问题描述:

_she_yesterday,she would meet the famous singer today.答案为什么是Had't,left?
不是如果省略的谓语动词是否定形式,不能用动词的缩略形式吗?

答案应该是: Had,not left
这是一个虚拟语气省略了if的倒装结构,原句是:If she hadn't left yesterday, she would meet the famous singer today.(如果她昨天没走,今天就能看到那个著名歌手了)
当虚拟语气的从句中有should,were,had(助动词)时,可省略if,用倒装,把它们放到主语的前面,但要注意如果从句是if的否定句,not不能和它们一起提前.
