The train has gone You two ___ on time A should come B must have come C ought to have come

答案:选A.The train has gone You two _should come__ on time.
解析:火车已经开走了.你们应该按时到的.
解析:这道题是考察should作为情态动词的基本用法.根据句意,第二句话是说应当做某事,责备他们应该按时来,不用使用虚拟语气.
A should come 应当来
B must have come 一定已经来了,表示对过去事情的肯定推测.
C ought to have come 这里不能用have,ought to come也是对的
D shouldn't have come 不应当来,不符合句意.
