1.此题考查倍数表达法结构.
2.倍数表达法一般有如下三个结构:
1)倍数词 + as + 形容词原级 (+名词) + as ...
倍数词 + as + 副词原级 + as ...
2)倍数词 + 形容词/副词比较级 + than ...
3) 倍数词 + 名词(短语/从句)
3.所以选项中必须先把倍数词twice置前,由此就可以排除ABD;
而C项是“倍数词 + 名词(短语/从句)”结构,其中的much代指不可数名词money.
twice much意思是“两倍一样(多的价钱)”.
4.按照倍数表达法的结构,该题答案也可以是:
twice much = twice as much money = twice more (money)
