由to be+过去分词构成。如：

【注】有时用不定式的完成体被动式(to have been+过去分词)：

2. 现在分词的被动语态
由being+过去分词构成。如：
The building being repaired is our library. 正在维修的那座楼是我们的图书馆。
Being protected by a wall，he felt quite safe. 有一堵墙保护，他感到很安全。
He was seen being taken away by the police. 有人看见他被警察带走了。
【注】有时用现在分词的完成体被动式(having been+过去分词)：
Having been invited to speak, Ill start making preparations tomorrow. 因为邀请我去讲话，我明天就得做准备。
3. 动名词的被动语态
由being+过去分词构成。如：
She likes being looked at. 她喜欢被人瞧。
He objected to being treated as a child. 他反对被当成孩子看待。
This question is far from being settled. 这个问题远没解决。
4. 过去分词没有被动式
过去分词本身可以表示被动意义，但它没有相应的被动语态形式。如：
The door remained locked. 门仍然锁着。
