英语中倍数的表达：谁能帮我做下这个题目？

Question

It is said Americans eat ________ as they actually need every day.

A. twice sugar as much B. twice as much sugar
C. sugar as twice much D. as twice much sugar

在网上搜了很多关于倍数表达的内容，但都是be+形容词形式的句子的倍数表达，没有实物动词的形式。
请高人指点，谢了。第一次提问，给20悬赏积分。
选的答案是B，但正确答案是C，不知道是什么原因，请解释一下。

Answer 1

B
【特别提醒】

“as…as”中间加入名词的句式：

●倍数+as+形容词+a/an+可数名词单数+as…

●倍数+as+形容词+可数名词复数/不可数名词+as…。如：

Last year my brother twice as big a new house as mine.

He has collected more than three times as many stamps as I (have).

I spent twice as much time on my studies as you did.
比较和倍数的表达
例：1998年6月四级第56题
Americans eat ________ as they actually need every day.
A) twice as much protein B) twice protein as much
C) twice protein as much D) protein as twice much
结合选项，本句的大意是：“美洲人所食用的蛋白质是他们实际需要的两倍”。表达倍数的方法是：…times as … as …，在两个as只见可用many（修饰可数名词），much（修饰不可数名词）和其它相应的词。所以答案是A)。 可能是答案给错了

Answer 2

具体情况，具体而定。若是be 动词，那么应该是be twice as 。。。as 的形式

而这里，sugar 是eat 的宾语， eat sugar 与 actually need 进行比较。

Answer 3

twice在as前后都没问题，但sugar只能在eat之后
