题型:不详难度:来源:
He _____ have completed his work; otherwise, he wouldn’t be enjoying himself by the seaside.
A.shouldB.mustC.wouldn’tD.can’t

答案
B
解析

试题分析:must have done表示对于过去动作所做的确定的推断,意为“(过去)一定做了某事”。根据He wouldn’t be enjoying …推断,他一定完成了工作。should have done表示“(过去)该做某事而没有做”;wouldn’t have done表示“(过去)实际上做了某事”; can’t have done表示对于过去动作否定的推断,意为“(过去)不可能做了某事”。故答案为A.
