问题描述：
________ before we depart the day after tomorrow,we should have a wonderful dinner party.
A) Had they arrived
B) Would they arrive
C) Were they arriving
D) Were they to arrive
答
选A.
答
A
答
如果他们后天来,我们本可以有一个不错的晚宴
the day after tomorrow表示将来时,我觉得选D
答
选A. 本句为虚拟语气的倒装
虚拟语气中主将从现，主句是should have（本应该做某事而没有做），从句要用had
含有if的虚拟条件句可省去if而把助动词had,should,were提到句首构成倒装。
