修饰词是否必须紧挨被修饰对象

none123

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,

(E) Plants acquire carbon more efficiently than fungi,

答案是c因为in the form ...结构修饰carbon，所以要紧挨。那到底应不应该紧挨呢？
ps：改变文章成分在文章中的地位是不是一定错？比如第一道题里面的E选项，本来主句中的are..被改成了修饰成分，而原文中的修饰成分 having amassed 却变成了主句成分的谓语动词。这种错误是不是致命的呢?

不一定。 基本是说modifier 必须touch  修饰主语。The man smokes outside the door who has been a teacher for 20 years and has beed respected as a professor in science.. 这个句子也是对的 虽然who 没有touch {The man}

misplace the right phrase or sentence 可能会造成歧义，改变句子原意，改变句子中心 等等。即使语法 很concision 都对 这种问题也是致命的
