The ground is all wet. It _________ last night.A.can’t have rained | B.may have rained | C.can have rained | D.must have rained |
|
答案
D |
解析
考查情态动词表推测。时间是last night,所以要用情态动词加完成时态表对过去事实的推测。can’t have rained表不可能下雨,和前一句矛盾,排除A;may have rained可能下雨了,把握性不大,和前一句不符,排除B;can不能用于肯定句表推测,排除C;所以选D,must have rained肯定下雨了,把握性很大,符合句意。 |
