Having suffered a great loss,
he is now regretting _____ his business abroad.
A.to expand B.having expanded
C.to be expanding D.being expanded
为什么,请详细解答,谢谢!

选B.
regret doing sth,固定短语,后悔做过某事.这样就应该从BD里边选了.你再想想他现在后悔的是不是他"过去"在国外扩展市场?从"过去"持续到"现在"是不是应该用现在完成时?退一步讲,即使你不会做,也可以推出来.前半句话是不是给你提示了?前边用现在完成时,为了保持时态一致,后边是不是也应该用现在完成时呢你想想.
