C.Columbus, the Incan highway, which was over 2,500 miles in length and extended 请问C哪里错了呢？

C选项没有main verb哦，并且in length不如long 简洁。看了其他解释说， C中extended是被动，含义变成了highway被延展，这一点我不是很理解，是不是因为and extended中间有个was 被省略了？

同意~~ 我也是，看完B以后觉得extend的主语是 the system了，没往同位语方面想。。。。。。

the system 和 the highway可以是同位语结构吗？？

extended 和 extending也是SC考点之一。

例题：
Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.

(A) extending
(B) extends
(C) extended
(D) it extended
(E) is extending

所以为什么D不对，was extended by who?
这题答案为A

睡不完的觉

B 简化：The greatest road system was Incan Highway and extended from A to B.
一直不知道为什么错。。。。

B的 , and extended 是不是没主语啊？

这里错在extending是伴随状语，不能用b项的结构，直接当谓语了，b的语法上是没错的

本题，很明显E答案的higway后面少了一个逗号
