his number would have been up

问题描述:

his number would have been up
语境:If my brother had driven home from bar that night,his number would have been up.Something bad would have happened.

即使不给出语境,也可以断言,楼上的回答是不合逻辑的!
one's number is up.是口语
意思是 某人节数已尽; 轮到某人遭殃,某人完蛋了!
知道这个知识点,这个句子就好理解了!
还有一个知识点是:
would+have+过去分词:表示过去本来要做某事却因某种原因没做成,通常用来说明某种情况.
这个句子的意思,自己理解下吧!
希望我的回答你能满意!
