Question

---- Please tell Tom about the meeting tomorrow.

---- We ______him yesterday.It is a little late ,in my opinion.

A．ought to tell	B．would have told
C．should have told	D．must have told

Answer

C

【解析】考察虚拟语气。根据yesterday说明是对过去的情况进行虚拟，使用情态动词+have done的形式。排除A。would have done会做某事；should have done sth本应该做某事（实际上却未作）；must have done一定做了某事（对过去发生事情的推测）。句意：—请告诉Tom明天的会议。—我们本应该昨天就告诉他的。在我看来，有一点晚了。故C正确。
