旧题新问：Prep2008-186 The greatest road system

shl020

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.

A.Columbus was the Incan highway, which, over 2,500 miles long and extending
B.Columbus was the Incan highway, over 2,500 miles in length, and extended
C.Columbus, the Incan highway, which was over 2,500 miles in length and extended
D.Columbus, the Incan highway, being over 2,500 miles in length, was extended
E.Columbus, the Incan highway was over 2,500 miles long, extending

这道题可以迅速排除A,C,和D.但是在B和E之间我有些迷糊。诚然看了其它帖子里的讨论，E作为正确选项我是接受的。但是对于B，我当时理解成的句子结构是The greatest road system...was the Incan highway, 至此svo齐全，然后over...和extended...都是作为后置定语修饰the Incan highway的。没绕出来我这个想法的错误在哪里，请大家指教！非常感谢！

C木有谓语呀～

嗯嗯，“over 2500 miles, 所以伴随结果就是捏 从xx延伸到xx了 ” 这个说法对的。自己刚才也复习了一下过去分词做后置定语的情况，如果过去分词做后置定语，那过去分词和它所修饰的词之间是被动的关系，那么"highway"被"extend"就肯定不对了。看来还是基本功太不扎实了@@，感谢回复和提示！

弱弱的问为什么C是错的啊。。。。。

其实这句话里面还是有内部联系的，over 2500 miles, 所以伴随结果就是捏 从xx延伸到xx了，而b是没有这个意思的。另外b的这个, and extended 中的extended和谁并列呢，并且extended用被动也是不对的。
