问题 ______ before we leave the day after tomorrow, we should have a wonderful dinner party.

选项 A、Had they arrived
B、Were they to arrive
C、Were they arriving
D、Would they arrive

答案B

解析 根据主句中的should have和从句中的the day after tomorrow可知,本句包含一个if引导的非真实条件句,表示对将来情况的虚拟。因此从句谓语动词用过去式(be动词用were)或“should/were to+动词原形”的形式。有时可以省略if,并把were,should或had提至句首。故选B。
