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,
请问，这里的d选项为什么错啊，drawing不能做结果状语吗？svo，doing  。  这里的doing修饰什么？我看了解释是这么说的Th e final descriptor in present tense, now
drawing conclusions … does not fi t the
opening clause, which is in present-perfect
tense (have amassed a wealth …) and seems
to modify adulthood.  不太明白啊，是说这里有歧义所以去掉吗？

可是这个句子的主语不是fossils吗，为什么之后并列的动词was butchered 的主语又变成了whale呢？求解~~

请问啊，不是收集完信息才会得出结论吗？drawing做结果状语啊，答案说的是前面动词是having amassed  所以drawing的修饰会有歧义。这是什么逻辑啊？

tinyhuhus

“收集完信息”就必然会“得出结论”吗？显然不是。
LZ可以结合OG 12中出现的其他题目（23，26，47, 66） ，仔细体会“必然性”这个规则。

哦。这样啊。我看了看你指出的几个题，有点恍然大悟的感觉，有几个的确也是我疑惑的。谢谢了！
