Unearthed in China, fossils of feathered dinosaurs offer the most dramatic evidence yet discovered of the close evolutionary relationship between dinosaurs and birds.

1. offer the most dramatic evidence yet discovered of the close evolutionary relationship between dinosaurs and birds
2. offer evidence more dramatic than what has yet been discovered of the close evolutionary relationship between dinosaurs and birds
3. offer more dramatic evidence of the close evolutionary relationship than any yet discovered between dinosaurs and birds
4. have offered the most dramatic evidence of the close evolutionary relationship between dinosaurs and birds that have yet been discovered
5. have offered more dramatic evidence than any that has yet been discovered of the close evolutionary relationship between dinosaurs and birds

答案是A，我的答案是E

D为什么不对啊？

A offer the most dramatic evidence yet discovered of    没有that又啰嗦

ed分词可以直接修饰名词不用加that

原文中用yet discovered修饰evidence 是强调 已发现的证据当中最dramatic的，不

是罗嗦， D选项直接把定语删掉，影响了逻辑意思，表达就没有那么精准了～

D,E 用现在完成时，意思就是：从过去开始一直到现在，这些化石都提供了最有

力的证据，逻辑含义错误。化石在过去还没被发现的时候，是不能提供最有力的证据

的，只有被发现以后，才能提供。

直接排除D，E。

B，C 用了than what has yet been discovered ，than any ，相当于比较的时候把

自己都放在一起比了，错误。应该是 any other fossils 才行。
