这两天刷OG，理解了N多doing 定语状语结构，晚上突然又不明白了。下边这两粒的 having有和不同哦

OG70
The first trenches that were cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence for centrally administered complex societies in northern regions of the Middle East that were arising simultaneously with but independently of the more celebrated city-states of southern Mesopotamia, in what is now southern Iraq.
C) having been cut into a 500-acre site at Tell Hamoukar, Syria
这个选项是错误的，但是不知道为什么having been 不行，因为这里边没有逗号所以我理解直接修饰trenches;

OG25
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

这个选项是正确的，有逗号但是可以向前修饰主语，S,doing,VO.

第一句一定是定语，所以这里having done是错误的。
第二句，虽然可以认为向前修饰，但仔细读句，发现它的作用是对整个句子的修饰，完全的状语，所以可以用having done。

having done结构可以做非限定性修饰不能做限定性修饰

是不是只有having done特殊啊，其它ving是可以做限定性修饰的

是的，因为其他ing的时态取决于被修饰的时态，而having相当于强调了完成时，所以不能做限定修饰
