——I left my handbag on the train, but luckily someone gave it to a railway official.
——How unbelievable to get it back! I mean, someone ______ it.

A．will have stolen	B．might have stolen
C．should have stolen	D．must have stolen

答案

B

解析

句意为“——我把我的手提包落在火车上了。但幸运的是，有人拾到交给了铁路部门。——失而复得，简直难以置信！我是说，本来可能有人会偷了去。”will have done将来可以完成，must have done一定做过某事，表示对过去事情的肯定推测，都与题意不符。should have done本来应该做某事，而实际没做，这就意味着希望有人偷包。might have stolen 过去可能做过，语气比较婉转或不肯定，根据句意选B。
