OG12-21 关于现在分词完成时态不能作定语修饰名词

tenny0109 · 发表于 2009-11-8 03:47:01

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 human brain grows and how babies acquire language.

如题答案是A，但having amassed 不是现在分词完成时态不是不可以当定语修饰名词Neuroscientists吗？

困惑..

怎么发上来这么多符号

做的是状语吧~??

难道中间有逗号隔开就可以了没有逗号就不行？

不是这么说,你可以这么看

它其实就是换了下位子,现在就是现在分词在句首做状语,修饰主语,主句主语就是其逻辑主语了吧??

嗯是刚才在“请教G12-第一题-伴随状语的用法”这个帖里看6楼的lcy19812000说：

“，doing”结构是状语，不可作逗号前面名词的定语。
这时GMAC的家规，记住就好，没什么好讨论的。因为根本就没有反例。

不知道可不可以这么理解

96. (29707-!-item-!-188;#058&003977)

In some species of cricket, the number of chirps per minute used by the male for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve as an approximate thermometer.

(A) for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve
(B) for attracting females rises and falls in accordance with the surrounding temperature, which can in fact serve
(C) in attracting females rise and fall in accordance with the surrounding temperature, in fact possibly serving
(D) to attract females rises and falls in accordance with the surrounding temperature, and it can in fact serve
(E) to attract females rises and falls in accordance with the surrounding temperature, in fact possibly serving

你看E,serving应该是做状语修饰number的,但这里它就有歧义作为temperature的后置定语

,doing是可以做逗号前名词的定语的,故有时候是有歧义存在的,到底是做状语还是做定语~

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
(C) while they have introduced some 100,000 dangerous chemical pollutants at the same time, and have
(D) but introducing some 100,000 dangerous chemical pollutants at the same time that have
(E) but at the same time introduce some 100,000 dangerous chemical pollutants, having

这题的E,我觉得也是有这样的歧义存在
