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

 

A.      offer the most dramatic evidence yet discovered of the close evolutionary relationship between dinosaurs and birds

B.      offer evidence more dramatic than what has yet been discovered of the close evolutionary relationship between dinosaurs and birds

C.      offer more dramatic evidence of the close evolutionary relationship than any yet discovered between dinosaurs and birds

D.      have offered the most dramatic evidence of the close evolutionary relationship between dinosaurs and birds （A）

E.       have offered more dramatic evidence than any that has yet been discovered of the close evolutionary relationship between dinosaurs and birds

我选D，答案A，其实没看懂这题。。。

我查了牛津字典，yet用于完成时态，可以跟在最高级的后面 i.e., the most comprehensive study yet of his poetry.

但A选项用了一个一般现在时，好奇怪！

不必过多考虑时态。没有时间状语要指向现在完成时。GMAT的语法里能用一般现在时的不会选其它时态。

2.      (= so far) used after a superlative

我觉得在GMAT 这个字yet除了连接词的用法外，其他把他当作so far代入，似乎都OK。

单纯就时态看，考题有yet在smiple present也有present perfect或past perfect

我认为D的错误还在于没有yet discovered这个时间限定，会造成“这些fossils怎么样都是最好的证据”，改变了原意。

yet discovered 是做定语修饰evidence，每句都有yet discovered，唯独D没有，可能是漏掉了，应该加上，加上后应该选D，yet要求用完成时

可以这样理解吗

yet discovered表示“已发现的”，做evidence的后置定语，为了便于理解，可以放到前面来修饰：fossils offer the most dramatic yet discovered evidence of the relationship between…
