__before we leave the day after tomorrow,we should have a wonderful party
答案是were they to arrive 还有 Had they arrived Were they arriving Would they arrive
一点这个倒装句的助词提前为什么是were是过去式 ,不是原形are 不是had或 did
二点 to arrive arrived ariving arrive分别在什么情况下用

were they to arrive 在这里是虚拟条件句,从时间状语the day after tomorrow（后天）来看是对将来的虚拟, 所以选这个
它等于If they were to arrive...

Had they arrived 是对过去的虚拟, 等于 if they had arrived, 与语境不符

没有这两种虚拟形式（Were they arriving 和 Would they arrive）

再问：虚拟条件为什么用 were这个是过去式但不定式to arrive表将来做的，就是
再答：将来的虚拟中虚拟条件句有三种形式were + to + 动词原形should + 动词原形动词过去式这些都是虚拟语气的特定形式，记住就是，不要按常规用法来推
