单选题
Americans eat ______as they actually need every day.
A、
twice as much protein
B、
twice protein as much twice
C、
twice protein as much
D、
protein as twice much
【正确答案】
A
【答案解析】
解析:本题考查倍数表达法。根据选项可知,本题采用的是“…times+as+形容词/副词的原级+as…”句型,即much修饰名词,应放在protein之前,twice表示倍数,修饰as much protein as,也应前置,故答案为[A]项。
