英语的被动语态由“助动词be＋过去分词”构成，其中be有时态、人称和数的变化。本文中，我整理了被动语态的相关知识，欢迎阅读。
被动语态的结构为“助动词be+及物动词的过去分词(p.p)”。被动语态的不同时态是通过be的时态变化来表示的，其人称和数方面应与主语保持一致。其具体变化为：
一般现在时：am/is/are+p.p.
一般过去时：was/were+p.p.
一般将来时：shall /will be +p.p.
现在完成时：have /has been +p.p.
现在进行时：am/is/are+being+p.p.
过去将来时：should /would be +p.p.
含情态动词的被动结构：情态动词+be+p.p.
