There are twice as many A as B=A are twice as many as

应该是一样的,我个人觉得。 再问： 请问 There are more than five times as many books as five years ago。five years ago后面省略了book吗 再答： 没有省略book。 这句话其实省略了一个now There are more than five times as many books （now）as five years ago。 as前后其实应该是now 和five years ago ，是这两个时间状语的比较
