being done / be being done / have been doing / having been done 有没有谁可以帮我好好分析一下

Question

它们的用法还有各自代表的意思，还有它们的区别。麻烦请写出例句，举例说明。谢谢。

Answer 1

being done；现在分词的被动语态，修饰名词，置于名词后面，作定语，相当于现在进行时的定语从句。 例如；
the house（ being built）=the house （which/that is being built）
be being done; 现在进行时的被动语态，作谓语；例如
The house is being built.
have been doing 现在完成进行时。表明动作从过去开始，持续到现在，还在延续。例如；
我学英语已10年了。
I‘ve been studying English for ten years. (还在继续学)
having been done ；现在分词词组的完成式，常作状语，置于句首，相当于一个从句，表明分词动作早于主句动作。例如；
Having been translated into several foreign languages, the novel was world famous.
=Because the novel had been translated , it was world famous.
相信你能理解和赞同吧！ 祝你进步！追问

being done 是不是都只是用来修饰名词，有时当它放在句首时又如何理解？ being done 和 be being done 是不是都是理解成某物现在正被怎样怎样？谢谢。

追答

being done放在名词后修饰名词没错。它放在句首时 作状语，相当于状语从句。
being done 和 be being done 都可理解成某物现在正被.....但后者作谓语，前者做状语，置于句首。

Answer 2

be being done与have been doing 做谓语使用的，前者表示某事正在被做（被动句），后者表示一直在做（主动句）
其余两个，我已解释过。
