May as well和might as well的区别

may [might] (just) as well…
意为“不妨”、“还是…为好”等,用 might 比用 may 语气更委婉.如：
I’m ready,so I might as well go now．我已准备好,因此不妨现在就走.
There’s nothing to do, so I may [might] as well go to bed. 既然没什么事可做,我还是去睡觉为好.
注：might as well 还可用于指过去的情况或用于比较两个令人不愉快的情况：
This holiday isn’t much fun; we might as well be back home. 这个假日过得真没意思,我们还不如呆在家里.
