如题所述
twice as much as 和twice as many as这两个词组采用了“倍数+as+形容词/副词/名词+as”的表达形式，均表示两倍之多的意思。但是，twice as much as 后面要跟不可数名词或数词，twice as many as 后面要跟可数名词。
例如：
1、Since 1951 the arctic has warmed roughly twice as much as the globalaverage.
释义：自从1951年以来，北极变暖的速度基本上是全球平均速度的两倍。
2. The numbers of the machiens are twice as many as those of ten years ago.
