2.been held 由“since ancient times”可知，句子要用现在完成时，又因各种各样的节日和庆典应该是被举行，所以要用现在完成时的被动语态。
3.been taught 句意：在日本，所有的学生小时候就被教会如何准备和应对灾害。根据句意以及时间状语“since a young age”可知，此处用现在完成时的被动语态。 4.have been recognized 句意：过去的几个世纪，沿着北卡罗来纳州海岸的灯塔是海上旅行者们公认的安全标志。recognize和the lighthouses是动宾关系，故用被动语态。根据时间状语“In the past few centuries”可知，此处应用现在完成时。 5.had been removed 分析句子成分可知，remove与computer构成逻辑上的动宾关系，应用被动语态，remove这一动作发生在returned之前，故此处应用过去完成时。
