回答網友讀者有關[ twice與double ]用法的問題

有位網友讀者(邦邦)昨天問了一個有關倍數詞的問題，以下是問題與我的回答。

dear teacher:  請教您，針對twice 與 double 仍有點疑惑，舉例：我該用twice 還是 double 呢？  The new machine is _______ as fast as the old one. （ A ） twice       （ B ） two         （ C ） double       （ D ） second  

Dear邦邦,

1)   你的例子的答案是(A)。

假如你要用[ as + adj/adv + as ]的句型，我就用下列例句來解說你的問題：

2)   使用[ twice ]

a) Denise’s purse is twice as much as I paid for mine. [ twice是副詞 ]

      b) Denise’s purse is twice the amount I paid for mine. [ twice是限定詞 ]

3)   使用[ double ]

Denise’s purse is double the amount I paid for mine. [ double是限定詞 ]

      = Dennis’s purse is twice the amount I paid for mine.

      = Dennis’s purse is twice as much as I paid for mine.

因為詞性關係，在使用[ double ]的用法裡，沒有與[ as + adj/adv + as ]連用的句型。
