问题：Theairlinerwashalfanhourlate,soI? 
The airliner was half an hour late,so I_____to the airport.A.  didn’t ne to hurryB.  needed not to hurryC.  needn’t have hurriedD.  need not to have been hurried
回答：nen't have done sth　 本没必要做某事　如　I dressed very warmly for the trip, but I　needn't have done so. The weather was hot. hurried  to the airport 的hurried是动词过去时 不是形容词 B. needed not to hurry  这里有to 说明是need行为动词 但行为动词的否定是助动词否定 是 didn't need to 而不是needed not to hurry   D need not to have been hurried  也是否定错了 而且hurried是动词过去时 (hurry to sp.结构中的hurry是动词)　A. didn’t need to hurry　至于这个选项　虽然他也是过去的　但根据句子意思　他已经来了　是本来没必要这么早来的　而needn't have done sth　是 ＂本没必要做某事的＂意思　用这个确切点　意思比较符合
