修饰词是否必须紧挨被修饰对象 - ChaseDream

Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, arenow drawing solid conclusions about how the human brain grows and how babies acquire language.E

(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，没有问题，但是 about the brain and its development from birth to adulthood应该是修饰知识的，但是却紧挨着years，这个是否有歧义啊？还是说over the past years 是副词，既可以放在 about the brain and its development from birth to adulthood之前也可以放在之后。有些题确实是考修饰对象问题的的，比如：

22.Plants are more efficient at acquiring carbon than are fungi,in the form of carbon dioxide, and converting it to energy-rich sugars.

(A) Plants are more efficient at acquiring carbon than are fungi,

(B) Plants are more efficient at acquiring carbon than fungi,

(C Plants are more efficient than fungi at acquiring carbon,

(D) Plants, more efficient than fungi at acquiring carbon,
