标题: PREP 2008 Q188 请教大牛~~
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,(A)

E.Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,

我能理解为什么A对,但D为什么错呢?理解成now drawing....做结果状语从句不可以么?——N从过去到现积累了大量知识...,然后导致今天的这个结论,没什么不通呀~求NN指教~~

NN~~你们在哪里。。。。

我觉这是因为:如果原句的逻辑意思没有错误,就不要改变原句的意思,D的话把主次变了,毕竟状语从句跟主句谓语相比的话还是次要的,所以,既然有比它好的答案,而且没有改变原句的逻辑意思,就不选这个多此一举的选项啦
我不是牛==!大家共同学习,如果不对的话大家探讨一下啦~

一上来我就having done直接把A扔了~~然后D就怎么看怎么顺眼。。。哎~估计考试考这类题还得错~~~

而且,这个题还有一个提示就是now,你想如果是D的话,主句动词是完成时,而状语一开头就是now,明显不太合逻辑嘛,我之前也错过这题,因为想到很多人解释having done 不能做状语,但是发现其实可以的,而且好像还很make sense!

我还不是很明白D中now为什么不可以做结果状语~~?——N从过去到现积累了大量知识...,然后导致今天(now drawing)的这个结论,没什么不通呀~

对于DE,原句划线部分后面的句子将变为now drawing solid... 对于此处的drawing首先,我们不能将其理解为伴随动作,因为DE选项中,都提到了have amassed这一现在完成时结构,而now drawing与该现在完成时有明显的时间GAP,故不可能时同一时间层面上的动作伴随。其次,drawing也不可能是结果状语,因为若是结果状语,其“逻辑主语”(其实是不存在逻辑主语的),应是主句整个句子,但很明显drawing这个词是由主句主语neuroscientists发出的,而不是主句整个句子,故也不对。最后,语法上只剩下做定语修饰前面紧邻名词adulthood的可能了。但是明显,这么理解从逻辑上肯定是不通的。故在DE选项中drawing用法没有一个是正确的。所以DE选项不对。

ing型的独主只有2种情况能够使用:
1) it should apply most nearly to the subject of the preceding clause ; and, even more importantly,
2) it should have one of the following RELATIONSHIPS to that clause:
* a direct and inevitable, immediate consequence
* simultaneous, but lower-priority, action

这个now drawing不是immediate consquence或者inevitable consequence,更加不是同时发生的事情
