With prices rising sharply, we now have to spend three months ago on basic living materials.
A. as twice much as
B. twice as much as
C. twice as more than
D. twice as many as

A. as twice much as(答案→)B. twice as much asC. twice as more thanD. twice as many as解析：考查倍数表达法。因为此处spend的宾语是指钱，所以选择much，as与as之间用的形容词的原级，故排除C,D。倍数必须放置于句型之前，排除A

这个答案应该是对的
