25.He went away without answering my question where the post office was.He _______a dumb man.
A.may be B.must be
C.can have been D.must have been

A. may be 表示推测, "也许,或许"
句意: 他没有回答我的"邮局在哪儿"这个问题就离开了. 他也许是个哑巴.
(must be "一定是, 准是", 不说话不一定就是哑巴, 因此不能选B)
( can have been是虚拟语气, 不适合; )
(must have been 是对过去情况的推测. 表示他离开那天一定是个哑巴, 这显然不合情理.
推测某人是个怎样的人,应该用一般现在时,因此D也不能选)
