Tom ____his homework yesterday, because he was in hospital all day.

A．can’t finish

B．couldn’t finish

C．couldn’t have finished

D．mustn’t finish

答案

解析

试题分析：考查情态动词表示推测。根据第二句的过去时，说明是对过去的推测，使用“情态动词+have done”对过去的情况进行推测。如果是对现在情况的推测，使用“情态动词+动词原形”；句意：Tom不可能完成他的家庭作业，因为他整体都住院。故C正确。
点评：使用“情态动词+have done”对过去的情况进行推测。如果是对现在情况的推测，使用“情态动词+动词原形”；
