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 1

C

考察虛擬語氣。根據(jù)yesterday說明是對過去的情況進行虛擬，使用情態(tài)動詞+have done的形式。排除A。would have done會做某事；should have done sth本應(yīng)該做某事（實際上卻未作）；must have done一定做了某事（對過去發(fā)生事情的推測）。句意：—請告訴Tom明天的會議�！�我們本應(yīng)該昨天就告訴他的。在我看來，有一點晚了。故C正確。
