标题: 求拯救一道题啊！！！OG13 25题~~

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
看了很多帖子都说D选项改变了句子重心什么的这点俺不是很明白呢求解
以及 OG上的解释 D，说now drawing conclusions....does not fit the opening clause 怎么错呢？那应该要咋样？
还有and seems to modify adulthood 看到prep语法笔记上不是说逗号后面分词做状语不是要修饰相邻句子的主语吗为什么会看上去修饰adulthood呢？
百思不得其解求大神相助啊！！！！感谢！！！！！！！！！！！

首先明确 V-ing的三种用法：1：伴随状语句子末尾逗号隔开 2：主系表句子中句子末尾逗号隔开修饰整个句子 3：句子末尾逗号隔开可以作为定语 1：伴随状语不可能动作要同时发生但文章一个是过去一个是现在所以不是伴随状语 2：主洗标也不是 3：所以drawing可以做 adulthood的定语也可以修饰主句主语问题应该实在这里。语法原则不是绝对的
