I heard they went skiing in the mountains last winter.
A.may not be B.won't be C.couldn't be D.mustn't be
A.may not be B.won't be C.couldn't be D.mustn't be
应该选C,因为从时态来看 “last winter”是过去时态,这句话是过去时态的虚拟语气,动词形式应该用过去时,所以选择C.
从另一个角度讲,这句话的陈述句是“I heard they must be went skiing in the mountains last winter.” 动词形式是“must be”,它的否定形式是固定的“couldn't be ”.
而“mustn't be”的意思是“不必的,不应该的”与题意不符.
