选择题
——Alice looks sad. Did you tell her about the accident?
——Yes, but I ______ her just before her final examinations.
A．should have told
B．shouldn’t have told
C．needn’t have told
D．must have told
答案
答案：B
考查情态动词。shouldn’t have done 本不应该做某事，而实际上做了。句意：艾丽斯看起来很伤心，你告诉她这个事故了吗？是的，但是我本不应该在期末考试之前告诉她的。所以选B。
