标题: 求助:关于svo,ving中ving作定语还是作状语的问题
有个语法点困扰我很久了。。大牛门帮帮忙吧!

svo+ving的形式。基本的我都明白,就是关于ving即可做状语也可做定语这点。是不是只要逗号前有名词就会歧异呢?还是说优先作状语,只要意思通就可以,不用考虑作定语的问题?快点醒我吧~~~


在语法笔记中看到的内容:
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
但是,下面这道题的解释又让我觉得有些冲突:
188.
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,    
E. Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,

笔记解释:
现在分词在句尾用逗号隔开,必须要注意的一点是这个结构从来都没有失去过“做定语”的功能,只是优先做状语而已,即优先修饰到前面主句的主语和谓语。如下题如果前面主句的谓语是完成时态,那么既然已经完成了,drawing就无法再做其的伴随,所以只剩下做定语的功能。

是不是说97里面having done作的是结果状语,所以即使主句是完成时也不影响句意呢?到底什么时候考虑ving做定语产生歧义的问题呢?


我的问题好麻烦,大家耐心看完吧!谢谢啦!

总结的来说,SVO,VING结构中,ving优先作状语,伴随修饰V,逻辑主语是S.但是如果原句是完成时,由于完成时是不能伴随的,所以ving只能做定语修饰the nearest noun,即O

97的解释我个人认为是有问题的,真正错误的原因是:
由于这里having gone不能伴随(因为have introduced 是完成时态),所以只能做定语,但是having done在gmat中是不能做定语的,所以这句话不对~

有一点LZ需要牢记,现在分词的完成时态(having done)绝对不可以做定语。只能作状语!!(任何一本语法书和教语法的教材都会明确的告诉你)。所以,97题的句子不能表达逻辑含义,是错的。

188题的笔记解释错误,having amassed 这里不是作定语修饰Neuroscientists,而是作时间状语从句修饰后面的主句谓语 are now drawing。

非常感谢!!
但是你为什么没有考虑到having done做结果状语的情况呢?从句意来看,也有因果关系啊。

那也是伴随的一种情况,可以称之为伴随结果。但是只要是主句是完成时态,就不可以伴随~
