语法大全{蓝皮} 86题

In his eagerness to find a city worthy of Priam, the German archaeologist Schliemann cut through Troy and uncovered a civilization a thousand years older as was the city Homer's heroes knew.

A. older as was the city Homer's heroes knew.

B. more ancient than the city known to Homer's heroes

C. older than was the city known to Homer's heroes

D. more ancient of a city than Homer's heroes knew

E. older of a city than was the one known to Homer's heroes

答案是B

C为什么不对？

老师说是虽然有比较时动词习惯补出原则，但当动词多于一个时就没法补出，就不用补出了，本题就是这样

但我觉着这里划线部分是做civilization的定语的， 怎么还跟前面 cut和uncovered 有关呢？

请会的高手们赐教

谢谢
