到底谁是谁的两倍啊？ 大全20-10新问

20-10.      Last year the worldwide paper industry used over twice as much
                fresh pulp (pulp made directly from raw plant fibers) as recycled pulp (pulp made from wastepaper). A paper-industry analyst has projected that by 2010 the industry will use at least as much recycled pulp annually as it does fresh pulp, while using a greater quantity of fresh pulp than it did last year.

If the information above is correct and the analyst’s projections prove to be accurate, which of the following projections must also be accurate?

(A) In 2010 the paper industry will use at least twice as much recycled pulp as it did last years.

(B) In 2010 the paper industry will use at least twice as much total pulp as it did last year.

(C) In 2010 the paper industry will produce more paper from a given amount of pulp than it did last year.

(D) As compared with last year, in 2010 the paper industry will make more paper that contains only recycled pulp.

(E) As compared with last year, in 2010 the paper industry will make less paper that contains only fresh pulp.

不看答案反推，各位能告诉我到底 F(fresh)是R(recycle)的两倍，还是R(recycle)是F(fresh)的两倍吗？

想了半天，总觉得这个as比较用的蹊跷，好像和学语法时习惯用法的完全不一样，绕不过弯来。

感情过路朋友指导，最好能举个例子，谢谢。

前面是后面的两倍，即fresh pulp是recycled pulp的两倍，Math题目中常见此句式。

twice as much
        fresh pulp (pulp made directly from raw plant fibers) as recycled pulp (pulp made from wastepaper)

遇到这种倍数问题有个方法，就是第二个as 后面的**（recycled pulp ）都是乘以这个倍数等于前面那个的XX
