解释
to have been + 过去分词 把完成不定式(to have done,表更早时间)和被动(be + 过去分词,表承受动作)结合起来。它表示主语在主句动作发生之前经历了某个被动动作:He claims to have been cheated(受骗发生在他声称之前)。常用于 seem、appear、claim、be said/believed/thought to 等动词后,以及情态词后:The painting is believed to have been stolen。当被动事件明显早于转述动词时,用它而不用一般被动不定式 to be done。

注意
对比一般被动不定式 to be done,后者指更晚或泛指的时间:He wants to be promoted(将来)vs He is proud to have been chosen(更早)。
