Question

--- Mary’s got crazy and has been sent to the mental hospital. Did you tell her boss about that?
--- Yes, but I _____ her husband first.

A．should have told	B．shouldn’t have told
C．must have told	D．needn’t have told

Answer 1

A

试题分析：句意：——玛丽得了疯病已经被送进精神病院了。你告诉她的老板了吗？——是的。但是我本应该先就告诉她丈夫的。Should have done 本应该做（实际上没做）。shouldn’t have told本不该告诉；must have told肯定已经告诉了；needn’t have told没必要告诉。结合语境，选A。
