问题 The ground is wet. It ________ last night.

选项 A、might have been raining
B、can have rained
C、should have rained
D、must have rained

答案D

解析句意：地面是湿的，因此昨晚一定下雨了。情态动词must除了表示“必须”外，后面加动词原形或动词的完成式可用来表示对现在或者过去发生的事情的推测，表示“一定是，准是”。例如：fudging by the smell, the food must be good. 从香气上来判断，这菜一定很好吃。He must have been there last week. 他上周一定在那儿。
