自己给自己顶一个。
具体说说我的疑惑点。

1、having done能修饰名词吗?
 比如 主语+谓语+宾语+having done.


抱歉这些没有找到具体的例题。只找到一个直接修饰主语的
Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.
    A Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are
    B Neuroscientists, having amassed a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are
    C Neuroscientists amassing a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are
    D Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood,
    E Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,


2、having done 能表伴随吗?
比如 主语+谓语+宾语,having done.

很负责的说,having done不能作为定语修饰名词。但可以作为状语。

主语+谓语+宾语,having done.(修饰主语n)
n+having done(直接修饰该n)

是这两类都不可以吗?

刚才有个地方问得好像不对。
如果是 主语+谓语+宾语,having done,
这里的having done 其实应该是一个状语。

应该是 主语+谓语+宾语+having done

having done 来修饰宾语n

这种确实不可以啊。看来看去的都被自己绕糊涂了。

谢谢你的解答啊!
