Be that as it may: A set phrase that acknowledges a previous statement as true but ultimately unable to override some fact or sway one’s thoughts on the matter. Used to mean that you accept that a piece of information is true but it does not change your opinion of the subject you are discussing. As in I know he’s tried hard; be that as it may, his work is just not good enough.
中文释义：be that as it may 是尽管如此，即使如此，尽管那样；话虽如此的意思， 即使前面陈述的是真实情况，但是最终不能推翻某些事实或改变某人对这件事的想法的。比如：I know that he has tried hard; be that as it may, his work is just not good enough. (我知道他已经尽力了，尽管如此，他的工作仍不太理想。)
