其实，现在分词的四种形式在句子中的功能不尽相同：
doing 定 状 补 表
being done 定 状 补
having done 状
having been done 状
其中最难把握的是being done 的用法。下面对其用法详细总结：
a，做后置定语，表“正在被...”
注意与done ,to do/to be done做定语的区别：
done 做定语表“已被....”;
to do/to be done做定语表“即将/即将被...”
例见以上前三例。
b 作状语 being done 做状语，表“由于...正在被....”，一般置于句首；
注意与being + adj., adj. 短语， 过去分词短语作状语相区别：
being + adj 做状语，表“由于.... 处于....状态”，一般置于句首；
过去分词短语作状语，相当于being + adj 做状语,表状态，一般置于句首；
adj. 短语做状语，表 伴随状态，一般置于句末；
e.g.
Being painted, the house looks like a mess. (由于正在被漆)
Being poor, hte boy can't go to school. （由于穷）（“处于...状态”而非“正在...”）
Engaged in his work, he didn't notice my entering.(由于忙于...)（“处于...状态”而非“正在被...”，相当于busy in...)
(Addicted to the film, Lost in thought, Devoted to his work, Busried in he books,等同理)
He was born blind/dumb/noble/disabled.
He came back alive/sound and safe/tired and hungry. (伴随状态)
简而言之，做状语时，being done 表动作，而being + adj ，adj.短语，过去分词短语都表状态。
c 做补语
主要区别 being done 与 done 做 补语的不同：
与作状语的区别类似，being done 表“正在被....”(动作)(必须是延续动词）
而done 表“已经被...”或“处于某状态”（动作结果或状态）（可以是延续或短暂动词）
e.g.
With such an important issue being discussed, I couldn't leave ahead of time.
With the most important issues discussed, I decided to leave ahead of time.
I saw my son being beaten by that rude man.
I saw my son beaten by that rude man.
With my glasses broken, I had to buy a new pair.
综上所述，being done 无论做定状还是补语，都强调“正在被....”强调动作；
done 做定状补表时则表示“已经被...”或“处于...状态（形容词化的那些词如addicted, tired,等）”，强调动作结果或状态。
