问题描述：
you are late for school today.you___to school earlier
A.ought to come
B.should have come
C.ought have come
D.should com
答
C错误。ought to才表示应该，后面加动词原形！D选项后面应该是come.A选项的意思是你应该来早一点！B选项的意思是你本应该早点就到的！有一种责备的语气在里面！更符合前面说的你今天迟到了更贴近！
答
答案为：B.should have come
这是考察should做虚拟语气的用法,
should +have done：表示本应该.而实际上没有.
全句翻译为：今天你上学迟到了,你本应该早点到学校的.（暗含有责备的意思）
