"having + been + 过去分词"是什么句型？请举几个例子，谢谢！

并不是所谓的完成进行时,完成进行时应该是:have+been+doing.
这里是完成时的被动作状语的情况,一般用在句首.
例如:
Having been blamed by the teacher, he does not dare to run away from school again.已经被老师骂过了，他再也不敢逃学了。
又如:
Having been told that he didn't pass the exam, he felt extremely sad.被告知没通过考试后，他极其郁闷。

having been finished是：
动词的-ing形式＋完成式 ＋ 被动式
意思是（某件工作）已经做完了
表示动作是先于主语的动作完成的
并且动作是主句主语的承受者
Having been cheated, I don't believe any girl at all.
被欺骗后，我再相信女人了。

是不是太绕了

如果你问的是have been + -ed分词，我再举例子：
The car has been cleaned.
车洗完了。 （意思是车是干净的了）
The book has been adapted into a movie.
这本书被改变成电影了，或已经搬上了银幕

OK? Take a rest!

现在完成进行时，可以表示现在进行的动作仍在继续，二爷可以表示动作刚结束。似乎考试一般喜欢抓住第二种解释。
例子。I have been watching TV.可以表示我刚才在看电视，但是现在已经没有看了。

比如说：昨晚10点之前一直在下雨！可以翻作：
She having been cried before 10pm last night.

完成时的被动式.不过是have been+过去分词.没有having been....
例:I have been told already.
He has been sent to the hospital.
