that has suggested the elephant descended from an aquatic animal, its trunk originally evolving
suggesting that the elephant had descended from an aquatic animal with its trunk originally evolved

题目分析：
略。
选项分析：
A选项：and是连词，应该连接两个句子。本选项and身后缺少谓语动词。
另外，本选项整个划线部分是evidence的定语从句，这个定语从句应该改为不定式短语。这点考查了“不定式和从句的区别”。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）。
B选项：定语从句错误同(A)。
C选项：本选项也是evidence的定语，是一个现在分词短语。这点考查了“不定式和ing的区别”。同理于选项(A)，本题中evidence的定语必须是不定式形式。另外，had descended是过去完成时，表示某一个在过去的过去发生的事件。由于证据表明的是“客观真理”，不是某一个事件，所以应该过一般现在时而非过去完成时。
D选项：“大象来自于水生动物”是一个客观存在的事实，所以应该用一般现在时而不是过去完成时。（该错误同选项(C)）
E选项：Correct. 本选项在语法和逻辑上均是正确的。
that... and that...
"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.
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.
C中的客观真理只能用一般现在时。
做题重在体会啊啊啊啊啊啊啊啊啊啊啊

而18OG 716中的C，“gather evidence suggesting XX”科学家是收集证据，是不是说证据本身就表明XX了呢？是不是说这个证据是已经存在的且已经被证明是可以来表明XX。
而这一题中的find，根据老师的讲解，这个是新的证据，是需要被发现然后来被证明是可以表明XX的。
descend from 表示下降或者沦落到
CD选项：had descended是过去完成时，表示某一个在过去的过去发生的事件。由于证据表明的是“客观真理”，不是某一个事件，所以应该过一般现在时而非过去完成时。
find用的意思不同，约束力也不同哟~登录 或 注册 后可以参加讨论
且“大象进化自水生动物”和“大象鼻子如何进化的”两者之间没有很强的因果联系或者主从联系，所以用并列表示挺好的
客观真理最好能用一般现在时表示
B has suggested现在完成时-截止到现在为止可以表明，之后不一定可以
C had descended错误 客观事实用一般现在时 evolved 不能被动进化 只能主动进化 所以evolved是动词过去式 with介词后面不能跟句子
--Ron
A选项，and后面无主语；B选项后面无主语；DE 选项相比，D选项前面时态用的不对；E选项前面时态用一般现在时表示一种客观事实，没毛病。同时，and前后两个句子均有that开头，平行关系成立
2. 第一个内容是客观事实 后一个内容是历史事件
if you mean to discuss ancestry, which is clearly the case here, then you must use "is descended".
是有这种说法吗？按照约束力那种理论？
