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 evolving

D. to suggest that the elephant has descended from an aquatic animal and its trunk originally evolved

答案是E

1。不定式可以做定语吗？

2。descend作为“是。。。的后裔”或遗传的意思时是不及物动词，为什么用被动？

下面是langman查的固定用法。

descend from somebody/something phrasal verb
1
be descended from somebody
to be related to a person or group who lived a long time ago
She claims to be descended from Abraham Lincoln. The people here are descended from the Vikings.
2
to have developed from something that existed in the past
ideas that descend from those of ancient philosophers

不定式可以做定语，比如，I have some work to do.这儿就是做定语

这道题,那个descend作为“是。。。的后裔”或遗传的意思时是不及物动词，为什么用被动？

为什么用被动????

不懂

这里descended 是形容词，不是descend的过去分词

to suggest 是不定式短语表目的,

C 里面 suggesting 如果做定语, 表示持续的,重复的动作,与意思不符合

1
be descended from somebody/sth.
to be related to a person or group who lived a long time ago
She claims to be descended from Abraham Lincoln. The people here are descended from the Vikings.

suggesting没错,但是C中的过去完成时是没有道理的

既然字典里都说is descended from是可以的,我们就当主动被动都可以吧.

反正选项里除了这一点都能找出其他错误 

PS:不过descended好象没有形容词这一说吧?

请问:这里E的its有没有指代歧义的问题呢？

its是不是也遵循就近指代的原则呢？

 NN, thx 

再顶!

希望有人解答啊!

我觉得its应该有指代的歧义的
