关于as old as的疑惑

33. Carbon-14 dating reveals that the megalithic monuments in Brittany are nearly 2，000 years as old as any of their supposed Mediterranean predecessors

(A)  as old as any of their supposed

(B)  older than any of their supposed

(C)  as old as their supposed

(D)  older than any of their supposedly

(E)  as old as their supposedly

Logical predication + Diction

The original sentence has two problems．(1) Comparisons must be logical and easy to follow The Brittany monuments are logically older than the Mediterranean ones．Therefore，the appropriate comparison uses the phrase older than，not as old as．(2)Adjectives，not adverbs，modify nouns．The phrase Mediterranean predecessors requires the adjective supposed．

A  Suggests two sets of megaliths are equally old，not that one is older

B  Correct．This sentence makes the proper comparison and uses the adjective supposed．

C  Suggests two sets of megaliths are equally old，not that one is older

D  Makes correct comparison；adverb supposedly used instead of adjective supposed

E  Suggests two sets of megaliths are equally old，not that one is older

The correct answer is B．

答案里说从逻辑上来讲应该是用older than，那么用as old as从语法上来讲对么？

上新东方的时候，听老师讲过as old as前面好像不能加2000years这样的时间词

在as … as 的结构中，第一个as的前面可以加上表示倍数的词、或是某些副词修饰语：twice , ( three ) times , nearly , almost , just , exactly , not nearly（根本不）, by no means（绝不）, quite 等等。上题中如果是 nearly as 2000 years old as 就顺了。
