prep08上面关于比较的一些解释

flywer

语法笔记在“比较之庖丁解牛”中谈到了as的用法，有一部分我不是很明白，请教大家

AS族的比较大同小异，as 可单独引导比较，也可以复合成as many as, as hard as 等形式，但ETS宗旨不变，如

Sand road costs twice as many to build as to manintain(类似于介宾比较）

Sand road costs twice as many to build as stone road do(主语比较,）

Sand road costs the govement twice as many to build as the residents.(宾语比较）

请问这里的cost后面为什么是跟的as many as？cost后面一般不是都接不可数名词（比方说时间、金钱之类的）吗？那好像应该用as much as呀？

另外最后这个宾语比较是不是可以补全为：Sand road costs the goverment twice as many as (costs) the resdidents.

谢谢大家~
