Question

Mr. White ___________ at 8:30 am for the meeting, but he didn’t show up.

A. ought to arrive    B. should arrive

C. should have arrived    D. was supposed to arrived

Answer

C

【解析】考查情态动词用法。句意：怀特先生本应该在8：30来参加会议的，但是他没有出现。

Should have done本应该做某事，实际上却未做；根据后面的did说明是对过去发生的情况的推测。故选C.

【名师点睛】

“should +have +done”意思是“本来应该做某事，而实际没做。” “shouldn't +have +done”表示本来不应该做某事，而实际做了。含有指责对方或自责的含意。

1. Tom, you are too lazy. The work should have been finished yesterday. 汤姆，你太懒惰了，这项工作本来应该昨天就做完的。

2. Look, Tom is crying. I shouldn't have been so harsh on him. 看，汤姆哭了，我本来不应该对他如此严厉。
