回答網友讀者有關[ twicedouble ]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 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。
