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!
