如果说： I ate twice as much apples as pears
那么到底： 苹果是梨的两倍，还是梨是苹果的两倍啊？
小弟的疑问，来源于一道逻辑题：
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.
答案是A，查了帖子都在讨论算法，而且都认为是Fresh=2*Recicled. 但没有解释为什么这个奇怪的twice as much as 应该怎样理解。
想了半天，总觉得这个比较用的蹊跷，绕不过弯来。
请过路朋友指导，就拿苹果和梨的例子解说则个，谢谢！
额。。这么貌似是逻辑区的。。。
确实是逻辑题。
但小弟确实被这个 twice as much as 搞糊涂了。
还是请路过的兄弟帮帮忙，因为在SC中习惯的 twice as much as结构中，好像没有碰到这种比较的都是宾语的状况，通常都习惯是主语来比。
所以这里到底谁是谁的两倍，就自己把自己绕进去了。
多谢多谢！
"I ate twice as much apples as pears"当然是苹果是梨的两倍啦呵呵
我的理解是：去年原生纸浆的使用是回收纸浆的使用的两倍。业内分析家认为，到2010年，每年回收纸浆的使用量将至少和原生纸浆的使用量一样多，而同时，在2010年，原生纸浆的使用量会比去年还多。所以选A。
第二个AS后面的就是比较的基准，前面的多少倍就是对比第二个AS后面的那个DD来说的。
多谢Christinee,你的解释很清楚。
一并谢谢楼上诸位了！
twice as A as B. A是B的两倍 A/B＝2/1
假设上年用了2吨F的纸，那么R纸就是1吨。（2F：1R）
今年用的F和R的比例是一比一。while using a greater quantity of fresh pulp than it did last year。就是说今年用了不止2吨F。就当今年用了还是2吨的F，那今年的R就是2吨。今年的2R比上年1R比，是twice。要是今年用了2。2F，那今年就用了2.2的R（上年用了1R）。所以怎么着，今年的R都是往年的2倍还要多
