过去完成时被动语态:在过去某个时刻之前,某事已经被做完
B2接续
had been + past participle
解释
had been + 过去分词把过去完成时和被动语态结合起来。它表示某个动作在过去某个更晚的时间点之前就已经被完成,而动作的执行者未知或不重要:The letter had been sent before she arrived。当较早的那件事是被动的时候,用它来理清两件过去事件的先后顺序。执行者可以用 by 引出,但常常省略。
例句
注意
这个结构常和 before、by the time 或 when 搭配:When we arrived, the room had already been cleaned。只有当先后顺序已由其他词表明时,才可以不用 had。
