TT 4-39

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B，但是感觉很模糊。不知道这里为什么其他选项是错误的。有没有DANN给逐一分析一下呢？？多谢啊！！！！

非牛

A discovered错误地修饰了evidence，它应该修饰fossils

C\E 比较错误，这里是比较主语fossils，any就算做代词也没有任何词可以代，所以than后面缺可以和fossils对等的成分

D 和 A一样

B fossils和what相比，what范围比fossils更广，相当于anything discovered，名词与名词做比较。正确
