关于OG SC21题选项D的一个疑问

Pythagoras · 发表于 2011-10-15 21:17:18

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.

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

OG Explanation:
D. The final descriptor in present tense, now drawing conclusions … does not fit the opening clause, which is in present-perfect tense (have amassed a wealth …) and seems to modify adulthood.

我对最后的seems to modify adulthood有点不理解，句末的V+ing形式难道不是修饰主句的么？

因为主句结构是N are drawing ^*&$^#$#
如果像D那样，adulthood后面紧跟的V.ing就有被误解为定语的危险，那样就完全改变了句子逻辑
不合理

D的主句是N have amassed ...., now drawing ... 吧

在prep08上找到答案了

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

同意楼上的，v-ing可做状语修饰整个句子，也可做定语修饰前面名词。

不过我在语法书上看见了这种主语+have +done...., v+ing +...... 形式的，ving是对前面句子的修饰，表示前面句子所造成的结果。所以个人觉得跟时态木有很大的关系，主要还是看逻辑关系吧。

~~~~请问下LZ
这是对应prep08上的哪一道题的解释吗？
