问题描述:

What would you do if it-------tomorrow?We have to go on with our work,since we have got everything ready
A.rains B.rained

A,if引导条件状语从句,时态遵循“主将从现”.即当主句用将来时的时候,从句用现在时.如 If it rains tomorrow,I'll stay at home.即使表示明天的动作,条件句也必须用现在时.可是题中是would,不是will,would是will的过去式及过去分词,所以我觉得应该是rainedwould是will的过去式及过去分词,但它不只是这样,would常常用来表达客气委婉,在这里就是表达客气而用的,并不是过去式。而且这道题中讨论的是明天要干嘛,不可能用过去式
