36.    (26354-!-item-!-188;#058&003133)

A group of paleontologists recently announced that a site in Utah has yielded fossils of some of the biggest armored dinosaurs ever found, and that they were at least 25 million years older than any similar dinosaur type previously found in North America.

(A) and that they were at least 25 million years older than any similar dinosaur type previously

(B) and they are at least 25 million years older than those of any similar dinosaur type that previously was

(C) and the fossils are at least 25 million years older than any similar dinosaur types that previously were

(D) fossils that are at least 25 million years older than those of any similar dinosaur type previously

(E) fossils at least 25 million years older than similar dinosaur types previously

这个题选D，我刚开始被A迷惑了，是因为and that很平行，这种原句本来是that and that的平行结构改成了同位语，但是记得XDF老师说原句结构最好不要改变，在这一点上有点混，请各位指教～～

我觉得不存在什么不改变原来句子结构的说法。关键看看句子的原意有没有被改变。在原意合理正确的情况下不要轻易改变。

这题中总的来说句子的原意是被改变了的。因为A中有一个重要的错误，就是没有补出those of

A group of paleontologists recently announced that a site in Utah has yielded fossils of some of the biggest armored dinosaurs ever found, and that they were at least 25 million years older than any similar dinosaur type previously found in North America.

(A) and that they were at least 25 million years older than any similar dinosaur type previously

(B) and they are at least 25 million years older than those of any similar dinosaur type that previously was

(C) and the fossils are at least 25 million years older than any similar dinosaur types that previously were

(D) fossils that are at least 25 million years older than those of any similar dinosaur type previously

(E) fossils at least 25 million years older than similar dinosaur types previously

D是同位语结构用在句子中没有问题,A固然平行但是主语they指代不明啊,容易让人认为是A group of paleontologists 

考试是灵活的，不是什么xdf老师总结出来的所谓规律,即便是用也要灵活不能生搬硬套!
