128. Australian embryologists have foundevidence that suggests that the elephant is descended from an aquaticanimal, and its trunk originally evolving as a kind of snorkel.
(A) that suggests that the elephant isdescended from an aquatic animal, and its trunk originally evolving
(B) that has suggested the elephant descendedfrom an aquatic animal, its trunk originally evolving
(C) suggesting that the elephant haddescended from an aquatic animal with its trunk originally evolved
(D) to suggest that the elephant had descendedfrom an aquatic animal and its trunk originally evolved
(E) to suggest that the elephant isdescended from an aquatic animal and that its trunk originally evolved
问题1就是历史遗留问题——OG对于B选项的解释the evidence still suggests these things about the evolution of the elephant and its trunk,so the present-perfect verb tense is inaccurate.
但是我们知道现在完成时用于:过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在并且有可能还会持续的动作或状态。(来自百度百科)
那么这个B选项中的has suggested我怎么看怎么都是对的,因为suggest这个动作发生在过去,同时到现在都是一直在suggest后面的内容,并且会一直持续下去,太切合现在完成时的用法了,所以怎么就不对了呢?我严重怀疑OG的解释!
我在这两个以前的帖子的时候注意到一个问题,bat斑斑说——“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】”,但是这里是suggest这个动词用的完成时态,而并不是进化,所以是suggest这个动作一直在持续。
问题2:关于C选项中with后面跟的成分,OG认为其实一个句子,我想问的问题是,如果我把后面这部分视为一个独立主格的话,难道with前面必须要使用逗号隔开么?更一般的情况下,使用独立主格的时候是不是必须使用逗号或者一对逗号把独立主格的结构与句子其他成分隔开呢??
