2019年mpa考试英语真题——虚拟语气884

{01}—Has Ham started out? He said he would join in the party.
—He ____. He is a man who always keeps his word. A.must have left B.need have left C.should have left D.could have left 解析：考查情态动词+have done，A是过去一定做了，B是过去本有必要做却没做，C是过去本应该做却没做，D是过去本可以做却没做，句意是：--Ham出发了吗？--他说他会参加聚会的。--他一定已经走了，因为他是守信的人。选A。
本题选A。
{02}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 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。
本题选D。
