标题: 对aeoluseros斑竹对having done 解释的疑问

问题源自新PREP sc1 188

188.
(26379-!-item-!-188;#058&001961)

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, 答案：A

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

aeoluseros斑竹对A项用having done作定语的解释是，having done不能引导限制性定语从句的而可以引导非限制性定语从句。但是请看旧PREP SC1 97题：

97. (29753-!-item-!-188;#058&003991)

Industrialization and modern methods of insect control have improved the standard of living around the globe while at the same time they have introduced some 100,000 dangerous chemical pollutants, having gone virtually unregulated since they were developed more than 50 years ago.

(A) while at the same time they have introduced some 100,000 dangerous chemical pollutants, having

(B) while at the same time introducing some 100,000 dangerous chemical pollutants that have

(D) but introducing some 100,000 dangerous chemical pollutants at the same time that have 答案：B

(E) but at the same time introducing some 100,000 dangerous chemical pollutants, having

问题：

1.对于A项，语法笔记上十分明确地说现在分词的完成时态不能作修饰语并没有考虑是否是限定性的问题，而且这里的having····也可以理解为是非限制性定语从句啊，为什么这里就不行呢？

2.就是语法笔记上说A项的having gone有作状语的歧义存在，我没有看出这里怎么能做状语，请讲解

3.怎样判断having结构在句中是作定语还是状语，像188题我觉得having···无论作定语还是状语都能够理解的通，有没有什么诀窍？

我想了一下，新PREP sc1 188题里的having结构不是作定语，而是状语，用having是因为amass这个动作在前,are now drawing 这个动作在后，不知道是不是这样啊。

同意LZ，having done/been done 做后置定语是一定不可以的，但可以做状语，prep上还有一道题是这样的

请NN帮忙，这道题真的很困惑。特别是我的第三个问题。

我对定语、状语的理解是这样的：有的时候同一个成分、结构可以做定语，也可以做状语，只要区分被修饰对象与结合时态等分析逻辑上能不能合理修饰就够了，没必要太在意是做定语还是做状语。也就是说，区不区分定语、状语都可以，关键是要明白定语和状语的功能都是“修饰”(有点像废话，不过我的意思是平时我统一把他们记为“修饰语”，只有在做题目解释的时候才区分一下)。

prep1-188中，A选项"having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood"，你可以把这个成分理解成状语，也可以理解为定语，修饰的都是Neuroscientists这个主体或这个主体发出的动作，只要你把having看做定语和状语时，句意理解起来是一样的，那么就没有歧义问题。

而prep1-97：Industrialization and modern methods of insect control have improved the standard of living around the globe while at the same time they have introduced some 100,000 dangerous chemical pollutants, having gone virtually unregulated since they were developed more than 50 years ago.这里面having可能修饰pollutants，也可能修饰they have introduced some 100,000 dangerous chemical pollutants整个分句，所以having产生了修饰歧义。

关键是逻辑先后
