呼唤版主和同学们帮忙看一个问题：OG128 完成时问题

deityc

Australian embryologists have found evidence that
suggests that the elephant is descended from an
aquatic animal, and its trunk originally evolving as a
kind of snorkel.
(A) that suggests that the elephant is descended
from an aquatic animal, and its trunk originally
evolving
(B) that has suggested the elephant descended from
an aquatic animal, its trunk originally evolving
(C) suggesting that the elephant had descended
from an aquatic animal with its trunk originally
evolved
(D) to suggest that the elephant had descended
from an aquatic animal and its trunk originally
evolved
(E) to suggest that the elephant is descended from
an aquatic animal and that its trunk originally
evolved

答案是E

OG对于B的解释：Th e evidence still suggests these things
about the evolution of the elephant and its
trunk, so the present-perfect verb tense is
inaccurate.

我疑惑的是，现在完成时应该有两个含义1）动作还在继续 2）动作的效果还在持续。

不管用哪个解释都可以说 Has suggest是对的啊。现在完成时并没有说现在这个动作已经不持续了的意思啊

再说了主句用的是 have found 按照OG的逻辑是 现在就不发现了么.......

B怎么看都是错的。。。
不单单是完成时的问题。这句话确实没有用完成时的必要
关键是后面根本就不知道他在说什么。suggest后面两部分都不是句子，而且descend做遗传讲时事不及物动词，所以不能用过去分词做定语表被动，而且两部分没有平衡。B一看就是不对的呀。

我知道 B不对 我所凌乱的是OG关于完成时的解释

版主也是同学的T T，不能这么歧视大四的孩纸~哈哈

完成时，第二个用法：【动作的效果还在持续】，你所说的表达并不准确。
更准确的说法是：【过去已经完成了的事情，其效果仍在现在有影响】。所以，那用完成时，可能就在表达【进化已完成，只是进化的效果持续至今】。

哈哈 版主同学， 按你上面这么说 我觉得has suggest 更对了，“过去已经完成了的事情，其效果仍在现在有影响”
影响还在啊，现在还是证明“大象的鼻子是.....进化来的”，效果还在啊

(B) that has suggested the elephant descended from
an aquatic animal, its trunk originally evolving

完成时仔细想想确实没有什么太好的反驳的理由
但后面宾语从句缺that，以及descended的时态是硬伤

its的指代也不明确，不像E通过句式平行可以找到指代elephant

恩  ls说的是 ，我也是看得出别的地方的问题，但是就是这句解释有问题
