在og和大全中经常有结构比较复杂的as……as出现，有时会造成困惑，特在此提问。
我知道A is as good as B 这是一个很简单的结构 是A is good 和B is good 的程度在做比较。
大全52的两个选项：
(C) failure to advertise the highest price in a range of prices for a service or product as prominently as the lowest
(D) failure to advertise as prominently the highest price in a range of prices for a service or product as the lowest 分别是什么在和什么比较呢？特别是两个as之间的东西我应该怎么看待呢？
记得有一个og题说：破土路 costs as much money to maintain as 柏油路
应该是：土路costs to maintain的money 与 柏油路 costs to maintain的money比
也就是说，两个as之间的东西应该是比较双方共同的东西，在看比较双方的平衡性时，都必须能够带上两个as之间的东西才行，对么？
og187中的一段话：four times as many Americans were killed as would later be killed on……是不是可以改写为：Americans were killed four times as many as Americans would later be killed on……
我主要是对这种结构中两个as之间可以放什么，以及怎么拆出来产生了疑惑，不知道我的问题大家能否看懂。呵呵 我都有点晕了 |
