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 E. have offered more dramatic evidence than any that has yet been discovered of the close evolutionary relationship
比如OG 68The first trenches cut into a 500-acre site at Tell Hamoukar,Syria, have yielded strongevidence that centrally administered complex societies in northern regions of the Middle East arose simultaneously with but independently of the more celebrated city-states of southern Mesopotamia,in what is now southern Iraq .
128.Australian embryologists have foundevidenceto suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved as a kind of snorkel.
而且A的yet不是用在完成时态里，we have not found the clue yet.这样的么？怎么可以用在一般现在时里呢？
求指教！

A&D 差在D 省去了yet discovered 在這yet 為adv 表 尚未 還 仍然 很明顯這樣D&A句意就有所不同了 A 是表示在未發現的close evolutionary relationship, fossil給了很大的證明 而D卻是表示已發現的close evolutionary relationship, fossil給了很大的證據 應該有感覺到差距！ 依照題意盡量不變原則 我想A preferable作者: fannybeibei 时间: 2010-8-10 12:14 呵呵，又看到fly了～～～ 懂了，谢谢哦作者: fly12404 时间: 2010-8-10 12:41

In 1926, in her second attempt to swim across the English Channel, Gertrude Ederle not only crossed the Channel against currents that forced her to swim thirty-five miles instead of the minimal twenty-one, but also set a record for speed, swimming the distance almost two hours faster than anyone had yet done.
the biggest/worst etc (something) yet used to say that something is the biggest, worst etc of its kind that has existed up to now: This could turn out to be our biggest mistake yet. Nordstrom’s latest novel looks like his best yet.
yet more/bigger/higher etc used to emphasize that something is even more than it was before or is in addition to what existed before SYN still: He got a call from the factory, telling of yet more problems. Inflation had risen to a yet higher level. yet another reason to be cautious The meeting has been cancelled yet again (=one more time after many others).
