求助一道语法题~

晒太阳阳阳阳阳

之前总结了prep08笔记关于现在分词和过去分词的修饰情况：
1.当过去分词在句末时，不管有无逗号，一般都是就近修饰名词；但偶尔也做状语修饰整个句子，如He hurried to the hall, followed by two guards. 修饰情况由逻辑决定；
2.现在分词在句末时，无逗号时作就近修饰的名词的定语；
3.当现在分词在句尾且前有逗号时，修饰邻近句子的主语，做主语的伴随状语或做句子的伴随结果。因此不能用句尾现在分词修饰前面句尾的名词；(在GMAT里，having been done的用法错误，应直接用done)
4.当现在/过去分词在句中且前没有逗号,修饰前面紧邻名词；
5.当现在/过去分词在句中且前后都有逗号，有歧义：1)修饰前面紧邻的名词，2)向后修饰后面句子的主语
里面说现在分词前有逗号时只能修饰前面句子的主语，但是做og18的时候发现有一道题就是错在逗号后的现在分析修饰有歧义，所以很困惑
把题目贴上来：
(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
(D) Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood,
请大家帮忙看看到底是我理解有问题，还是笔记存在疏漏，谢谢了

有道理~做题的时候没太关注到

我认为排除到AD两项，用语义逻辑比较直接。
科学家（积累了知识）所以才能 draw solid conclusions
两者比较来说，主动作自然是draw solid conclusions，逻辑上来说积累知识是为主动作做铺垫的。

找了Ron的解释~
this sort of modifier should actually satisfy TWO requirements:
1) it should apply most nearly to the subject of the preceding clause (as you've said); and, even more importantly,
2) it should have one of the following RELATIONSHIPS to that clause:
* immediate consequence
* simultaneous, but lower-priority, action
here, this modifier doesn't have either of these 2 relationships to the main clause, so it's used inappropriately.
在这种修饰情况下必须满足上述两个条件，即既要修饰主句主语，又要作为整个句子的伴随动作或伴随状语，D在这里是不能作伴随动作或结果的，因为伴随结果指的是主句动作带来的基本的、不可避免的结果，而这里的drawing并不是amass的必要结果，所以错误。我懂了！！

ron之前说过comma+ing的是修饰之前整个clause,放在这里显然是逻辑上会有问题的 drawing conclusion显然无法 ...

修饰整个句子吗~也可以说是伴随动作或伴随结果吗？

这样一看确实，逗号+which一般要紧跟被修饰对象，这种修饰题还是多比较的好~谢谢你！

ron之前说过comma+ing的是修饰之前整个clause,放在这里显然是逻辑上会有问题的 drawing conclusion显然无法修饰scientist have amessed...因为drawing conclusion明显是在amess这个动作之后，不可能去修饰前一个动作

By merging its two publishing divisions, the company will increase their share of the country's $21 billion book market from 6 percent to 10 percent, a market ranging from obscure textbooks to mass-market paperbacks.
A. their share of the country's $21 billion book market from 6 percent to 10 percent, a market ranging
B. from 6 percent to 10 percent its share of the $21 billion book market in the country, which ranges
C. to 10 percent from 6 percent in their share of the $21 billion book market in the country, a market
ranging
D. in its share, from 6 percent to 10 percent, of the $21 billion book market in the country, which ranges
E. to 10 percent from 6 percent its share of the country's $21 billion book market, which ranges
其实就像这个题，BE， B的which修饰逻辑意思层面来讲只能跳跃修饰market，所以B单独拉出来是没有错误的, 但是E就因为离名词更近所以更好.    修饰我感觉一定是对比出最好的就行

可能是我思维太僵化了记住了语法规则做题的时候一看到相悖点就排除排除...
那这个题now drawing是既可 ...

D我记得是讨论挺多的，做结果状语我觉得也是还行的，别太纠结这么小的点，记得当时看这道题搜cd, 大牛们讨论了好几页。

我记得昨天看RON解释过类似的题，你说的第五点，好像并不存在歧义，  S, ed+.., V+O,还是挺常见的用法。（ ...

第5点我觉得你说的对~具体情况具体分析
