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
为什么OG解释说D 中now drawing conclusion seems to modify adulthood? 逗号之后现在分词不是修饰主句的主语的吗?求大神指点
请仔细读句子,本句的重心在于are now drawing solid conclusions about 。。。。是在描述事件本身,是句子主干。而having amassed 说到底只是对Neuroscientists进行补充,不讲述事件,所以在重心上应属修饰成分。所以各个答案比较而言,A比D更合适些。
