须茜盼13775925206 ______ I have been here over 20 years.这个句中虽然出现了been ,但它不是被动语态而是现在完成时态.been 用于被动语态结构为(have/has been done).它的句式如下:主语+have+been+done.My homework has been finished . 我的家庭作业已被完成.主动语态: I have finished my homework.been 用于被动语态 是完成时态的被动式 have/has been doneI have been here over 20 years.你给的句子been 后面没有done, 它不是被动语态.
