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

正确答案是A。我是同意的。我的问题在于选项B。OG的答案解释B项中，over the past twenty years是修饰adulthood的。但是to adulthood是一个介宾语结构，介宾结构里的名词一般不是修饰不到吗？？？？？？

谢谢了O(∩_∩)O~

OG没错啊，经常耍的把戏之一，misplaced modifier！介词短语修饰preceding noun,一定要根据逻辑判断清楚modifier的位置是否正确...

LS的 misplaced modifier的解释很对，即使是修饰不到介宾结构，over the past twenty years在这个位置上也没办法修饰having amassed。

那再请问，会不会是修饰development呢？我经常搞不清修饰。
