OG-SC-21（12版）解释说: The final descriptor in present tense, “now drawing conclusions … ” does not fi t the opening clause, which is in present-perfect tense (have amassed a wealth ...) and seems to modify "adulthood"
可是我就是seems不出这个意思来。不知道怎么理解。 有人说：主句动作是完成时，所以已经完成了，就没法伴随了。 Does it make any sense??? 不理解唉。。。 现在不是说SC越来越靠逻辑意思和句意理解了吗？ 所以我真的很希望弄清楚这里面的道道唉。。。 希望好心人帮我点拨一下。作者: fdrandom 时间: 2011-9-8 10:51

选A么？ 我以为，D和E都改变了句子的重心，从句->主句，这不好。作者: 毛毛carina 时间: 2011-9-8 11:24
首先，这道题的确可以靠逻辑意思选出答案
Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, now drawing solid conclusions about how the human brain grows and how babies acquire language.
