复盘笔记：A. that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolving that the elephant... and 缺that its trunk 平行不对 B。 that has suggested the elephant descended from an aquatic animal, its trunk originally evolving the elephant and its trunk 要有连词； C。suggesting that the elephant had descended from an aquatic animal with its trunk originally evolved had descended from 这个时态就不对， 大象还在 怎么也至少是个现在完成时吧。 另外， with its 形容aqual animal 所以再evolve 这个意思就不对了。 D。 to suggest that the elephant had descended from an aquatic animal and its trunk originally evolved had descended 时态错误； to suggest that the elephant and 缺that 平行有问题1

即使不看descend的问题也有其他问题。C的问题是独立主格里的evolve成了被动态，D的问题是要表达俩宾语从句并列的话后面its trunk前面也得加that，B的问题是宾语从句的that不可以省略

不知道为什么点击不了回复…那就在这儿说一句，根据Ron大神的解释，A, and B表示A和B无关。eg: there was a lot of traffic this morning, and i was late. 这句话表明我迟到与交通堵塞无关，可能有别的原因，是两个独立的陈述。但要是说 there was a lot of traffic this morning, and thus i was late.说明我迟到是因为交通。

Isabel730回复entropy
我感觉加了逗号，前后就是两个独立的分句了，而这里明显不是，and前后都是suggest的内容，its trunk originally evolving明显不能和Australian embryologists have found evidence并列。所以A选项即使加上that可能也有问题（个人意见，仅供参考，希望有小伙伴告诉我这样想对不对）

胡说八道，"evidence to suggest" and "evidence that suggests" are both acceptable in this sort of context. neither is a basis for elimination.

key split是大象的起源和大象鼻子的变化是两个发现，逻辑上应该用两个that clause并列。

何闭关
"evidence to suggest" and "evidence that suggests" are both acceptable in this sort of context. neither is a basis for elimination. normally you would see "evidence that suggests..." however, they've used "evidence to suggest..." here, in order to avoid writing evidence THAT suggests THAT xxxxx. not because it's wrong -- just because it's ugly. "suggesting" should be fine in this case. "has descended" means "has moved downward". this can be in either a literal sense (he has descended to sea level from a height of 8000 feet) or a metaphorical sense (i don't want to descend to the level of common street thugs), but it can't refer to ancestry. if you mean to discuss ancestry, which is clearly the case here, then you must use "is descended". "is descended from" is indeed a description of a condition in the present

为什么不用that suggest，而是to suggest？ 看helr大神的解释是，不定式与从句的区别：用之于本题，主句“澳大利亚胚胎学家发现证据”这件事会直接影响“证据能表明大象的进化史”这件事的发生与否（如果不发现证据，证据自然什么都无法证明）。 但是我还是不太懂，我觉得”发现证据“并不影响”证据能表明大象的进化史“。对于这个解释很模糊。
