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,

答案是A OG对D的解释为 the final descripor in the present tense, now drawing conclusion...does not fit the opening clause, which is in present-perfect tense(have amassed a wealth..) and seems to modifey adulthood.
为什么 doing 不能跟在have done 的后面呢，各位大仙给解释一下呗谢谢谢谢～～～

自己顶一下大家帮帮忙~

这里的doing只有两种用法，表示伴随或者结果。表伴随的话，不能用一个正在进行的动作表示一个已经完成的动作。。。
表结果的话，从逻辑上来看，drawing solid conclusions并不是 amassed a wealth of knowledge 的结果。

关于2楼hehe316的解释，我觉得D中的drawing 也可以作为结果解释啊，为什么你觉得不可以作为结果解释呢？

我有一点不明白，在解释D项
The final descriptor in present tense, now
drawing conclusions ... does not fit the
opening clause,
which is in present-perfect
tense (have amassed a wealth ...) and seems
to modify adulthood.
为什么是只修饰adulthood

现在分词的伴随语-now drawing conclusions。。。。
按照意思理解不可能修饰现在完成时这个句子，所以语法上只能修饰adulthood，所以是错的

个人认为：drawing前面有个now，和前面句子的时间形成逻辑上的对比，所以最后一句now drawing。。。做伴随状语就不合适了。即使做定语也不合适吧。

doing 做定语肯定是不可能，但为什么不能做伴随结果呢。have done 是说他们过去二十年已经...，这个动作的结果是：现在得出...结论，不行吗
