—Actually, you________the party. It was canceled at the last moment.

A.didn’t need to attendB.needn’t have attended

C.shouldn’t have attendedD.shouldn’t attend

【答案】A

【解析】

考查动词need的用法。句意：——对不起，昨天错过了你的派对因为一位意外来客。——事实上，你没必要来。它最后取消了。didn’t need to do没有必要做某事，而实际上也没有做；needn’t have done本没有必要做某事，而实际上却做了。根据Sorry, I missed your party yesterday because of an unexpected visitor.可知，实际上没有参加派对，所以应用didn’t need to attend。故选A项。
