having done在非谓语中的用法
having done在非谓语中的用法如下:
having done是现在分词或动名词的完成式 。
Having been done,是现在分词或动名词的现在完成式的被动形式。
二者都表示先于其他动词发生或完成的动作。前者主动是后者是被动。如果需要表示先于其他动词发生或完成的动作可以用该形式。
不过作状语时一般用过去分词done,表示被动和完成而不用having been done。
如having done my home work,i went to play basketball.
现在分词的完成形式作状语与句子主语是主动关系其动作先于谓语.。
Went my home work done i went to play basketball.
这是过去分词的独文主格结构作状语。过去分词与自带的逻辑主语是被动关系。
