21.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.

(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,没有异议。 但是我觉得还是不严谨,请问NN有没有一个考点,是指时间状语的位置引起歧义的,虽然这道题别无选择。 可是over past twenty years 放在knowledge后面,是明确修饰knowledge么,有没有歧义:如果是修饰knowledge,就是积累了过去20年的知识,如果是修饰amass的则是用20年积累的知识。 大家讨论一下,别沉啊,没看到有专门讨论og12新题的帖子。

挺明确的。在这个结构中,over past twenty years 应该优先修饰 谓语 have amassd |
