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，但是想知道C错在哪里了？

1）ancient用来表述civilization更好

2）S uncovered a civiliaztion than {i)代词或新名词; (ii)had done S（过去时间概念）；(iii)did T （S和T的动作对象比较）

不外乎这三种情况，不存在S do A than is B. （A, B比较）
