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,

若将D选项代入原句，后半段如果要表伴随状语， now drawing部分应该如何修改？

不用分词结构，句子应该是
Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, and they are now drawing solid conclusions about how the human brain grows and how babies acquire language.
能够采用分词结构，第一点一定要主语相同，第二点是谓语间的逻辑关系，本题明显第一个谓语动词是第二个的原因状语，所以第一个用分词结构。
如果第二个用分词结构，则第二个谓语是第一个谓语的结果状语，显然，不符合他们的逻辑关系

doing只能做伴随状语和结果状语，怎么会有原因状语一说？？？

用现在时修饰现在完成时，不符合逻辑。

同意LS

好像没有看到做原因状语的吧。。。

doing 在“句末”只能做伴随或结果状语……用作插入成分的时候只相当于一个形容词，可以是原因状语……I think
