语法问题having done 和done
好象感觉差不多 比如having finished homework,he went out to play 和with his homework finished,he went out to play
或者说第2句用with his homework having been finished 可以挖
如果可以的话意思上什么区别

having finished homework,he went out to play
这个句子是属于非谓语的一个考点,having+pp,是现在分词的完成形式,在这个句子中“having finished homework,he went out to play”是现分短语做的状语,表示分词动作发生在主句谓语动词之前,先完成作业,再出去耍.
with his homework finished,he went out to play
第2句用with his homework having been finished,这是with的复合宾语做状语,但是你这个句子有一点问题,因为with的复合宾语结构中没有with+n+having的结构,你需要把这个问题在看看
having done 是用进行态来表示已经发生或者正在发生的事情
to have done 是表示将要去做 目前还没做
这种表示法很常见的.
意思上差不多吧
过去式只是纯粹的表示 完成的动作
过去完成式刚有点强调完成的状态,
一般自己用时都可以,只有考试时选择时,要故意考你的语法时才去区别
