It’s reported that the United States uses energy as the whole of Europe.
A. as twice
B. twice much
C. twice much as
D. twice as much

A. as twiceB. twice muchC. twice much as(答案→)D. twice as much解析：考察倍数表达法。“A+倍数+形容词或副词的比较级+than+B”，表示“A比B大（长、高、宽等）多少倍”。“A+倍数+as+形容词或副词的原级+as+B”，表示“A正好是B的多少倍 “……times+more+名词（可数或不可数）+than+被比对象 “A+倍数+the size/height/length/width，etc+of+B”，表示“A正好是B的多少倍 “……times as many/much+名词+as+被比对象 “……times+what+从句，根据结构可知，D正确

就是这个解释
