请教下各位,OG12- 128关于its的指代问题
128. 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
1、关于E里的指代,理论上可以指代elephant也可以指代an auqtic animal吧,可是为什么没有产生歧义呢?是因为两个that从句平行,所以its必须和前一个从句的主语一样么?还是因为aquatic animal没有trunk,所以不会产生歧义?个人偏向后者的解释,想问前面一种解释可以么?因为做题的时候真的不知道trunk是象鼻啊- -直接排除了这个选项。
2、丢人地问一下,我有点混乱了。have found evidence that 后面不是应该跟过去式么?为什么是is descend from呢?是因为evidence表示定理,必须用现在时,还是因为have found that后面本来就是跟一般现在时?
谢谢! |
