The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, which, over 2,500 miles long and extending from northern Ecuador
through Peru to Southern Chile.


B.Columbus was the Incan highway, over 2,500 miles in length, and extended
E.Columbus, the Incan highway was over 2,500 miles long, extending

B不好：be动词与一般动词并列
E不好：前面修饰语太长，重心不对

本题选E
如果我们就此认为be 动词与实意动词 不能并列， 再看下一题

Fossils of a whale that beached on an African shore more than a million years ago and was subsequently butchered by hominids have been recovered by paleontologists.

A.that beached on an African shore more than a million years ago and then was subsequently butchered by hominids has

B.that beached on an African shore more than a million years ago, which was subsequently butchered by hominids, has

C.having been beached on an African shore more than a million years ago and subsequently butchered by hominids, have

D.having beached on an African shore more than a million years ago and then subsequently were butchered by hominids have

首先就把A排除了，可答案是A

所以，be动词 到底能和 实意动词 并列吗？

我觉得第一题的B不是因为并列，而是逻辑。system extended。。。,你不觉得讲不通吗？
E把主语改成了highway并用doing做伴随状语，回避了这个问题。

所以，我认为be做系动词时，可以和有实意的动词并列，但是做主动词时不可以。

这题不是因为并列才改成这样，而是因为over 2,500 miles long 和 extending from ...  to ...说的是同一件事情，都是说这个highway怎么怎么长，因此后面用一个分词结构“extending from ...  to ...”来作为对“over 2,500 miles long”的进一步解释
