高一英语题目

Joe ____ here by now. That's too bad. We can't have the meeting

without him.

A.ought to be
B.should come
C.should have come
D.may have come

为什么 A 和 C 不可以呢？为什么 B 是对的呢？谢谢！

Answer 1

A.ought to be没有责备，抱怨的意思，而原句“That's too bad”“ We can't ...”则有责备，抱怨的意味，故用B.should come.

C.虽然有by now，但come是非延续性动词，故不用should have come而用should come.

Answer 2

should do+除了应该做，还有另外一个意思：本该做什么而没有做；
ought to do+没有此用法；
should have done+用于过去式。
