标题: OG12-21 sc
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 brainand 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

对于D选项OG解释：解释: The final descriptor in present tense,now drawing conclusions....does not fit the opening clause, which is in present-prefect tense(have amassed a wealth)and seems to modify adulthood.
我想问一下为什么不能把 ”now drawing solid conclusions"看为“have amassed"的直接结果呢？（因为前20年积累了大量的知识所以现在得出可靠的结论啊）谢啦～～～～

首先，comma Ving 表示consequence 的时候必须是“肯定的、无法避免” 的结果； 20年的只是的知识的累积并不一定就能够得到draw the conclusion （援引Ron 的解释）

其次，如果硬要说是结果的话，D选项的句意的重心也和原来的句意不同。Intended meaning 是要强调 are drawing conclusion 这个部分所以将 having aamassed... 用modifier 的形式来表达以示主次之分。而D选项却将主次换了个位置

楼主加油

二楼解释很棒！说点我的想法。这道题目考的并不是简单的语法，而是逻辑。

如果（1）和（2）标注如下，那么（1）和（2）是否同时发生（simutaneously or sequentially)？如果同时发生，（1）和（2）有没有因果联系（或先后关系）？

A. Neuroscientists, (1) having amassed a wealth of knowledge ..., (2) are now drawing solidconclusions...

D. (1) Neuroscientistshave amassed a wealth of knowledge ..., (2) now drawing solid conclusions ...

选项A，（1）和（2）可以同时发生，因为having amassed是present-perfect verb tense，已成事实。在神经科学家们做结论时，他们确实掌握了一些知识，意味着二者可同时发生。这些知识是他们做结论的原因。

选项D，（1）和（2）搭配没有语法错误，但有逻辑错误，（1）发生在过去，已经完成，而conclusion是现在（now）才得出，有了now这个词，（2）就不是紧随（1）其后，用comma verb-ing这个modifier修饰main clause意思不对。如果是修饰adulthood，显然也不是原句的intended meaning。

有没有大神讲讲 ,ing 这段修辞的是什么啊？他不能修辞名词吧。
Neuroscientists, （having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, ）

同样的情况
D) Many people, willing to admit that they lack computer skills or other technical skills, are disinclined to recognize that their analytical skills are weak

这个 ,ing 怎么modify non?
跪求大神

就是说 comma ing 是可以直接修辞名词的越来越混了
