在做非谓语动词做壮语时很容易碰到这种体型，请问怎样把他们充分的区别开来？最好有例子
非谓语动词作状语，其强调与主语之间的关系。现分作状语，其与句子的主语是逻辑上的主谓关系（及主谓关系），而过分作状语，其与句子主语是逻辑上的动宾关系（及被动关系）。having done作状语，强调的一是个先于谓语动作完成的主动动作，doing作状语，其表示与句子的谓语同时发生或不强调时间只强调与句子主语之间的主动关系，having been done作状语，其强调的是一个已完成的被动动作，侧重于时间上已完成，若不强调时时，可以用过分来替换，done作状语，表示与主语之间为被动关系。

i省略的形式，其实都是一种书面语，口语一般不喜欢省略的。
(after he has finished )After having finished his homework, he went out to play football.(强调动作有先后，主动关系)
(since he saw)seeing nobody in the room, he decided to stay there for a while..(主动关系)
(after we have been punished )After having been punished by the teacher, we don't behave like that any longer.动作有先后、被动动关系
（because they were led by）Led by the old elephant, they went on looking for the water.（被动关系本回答被网友采纳
