() this afternoon you would have to wait for another chance

这题考查的是倒装句和虚拟语气语法.
在虚拟语气条件句中从句谓语动词有 were, had, should 等词,可将 if 省略,把 were, had, should 移到主语之前,采取部分倒装.
这道题的后半句 you would have to wait for another chance next time.可以看出是虚拟语气,那么前半句的the boss的谓语应该使用虚拟语气形式,be动词变成were.
在倒装之后,Were提前到句首,省略if,即是：Were the boss not to return this afternoon, you would have to wait for another chance next time.
这句如果不用倒装的话,即为：If the boss were not to return this afternoon, you would have to wait for another chance next time.
满意的话,记得采纳咯~
