标题: 一直没搞明白题目~ 所以做不出~ 题目到底在说啥？ [打印本页] 作者: promiselu 时间: 2010-8-17 18:22 标题: 一直没搞明白题目~ 所以做不出~ 题目到底在说啥？ Gortlandhas long been narrowly self-sufficient in both grain and meat. However, as per capita income in Gortland has risen toward the world average, per capita consumption of meat has also risen toward the world average, and it takes several pounds of grain to produce one pound of meat. Therefore, since percapita income continues to rise, whereas domestic grain production will not increase, Gortland will soon have to import either grain or meat or both.
“and it takes several pounds of grain to produce one pound of meat.” ！为啥要用几磅谷子生产一磅猪肉？ 这个It是什么？
Which of the following is an assumption on which the argument depends? (A) The total acreage devoted to grain production in Gortland will not decrease substantially. (B) The population of Gortland has remained relatively constant during the country’s years of growing prosperity. (C) The per capita consumption of meat in Gortland is roughly the same across all income levels. (D) In Gortland, neither meat nor grain is subject to government price controls. (E) People in Gortland who increase their consumption of meat will not radically decrease their consumption of grain.作者: grubesure 时间: 2010-8-17 20:58
it takes several pounds of grain to produce one pound of meat. 不就是to produce one pound of meat takes several pounds of grain么.... 猪要吃谷子把作者: rudder26 时间: 2010-8-17 21:10
题目大致意思是 G城过去人穷，吃肉吃grain少，但现在有钱了，肉需求自然就多了，并且肉的增加需要grain来支持，但是生产力不给力啊~所以（结论）要进口,肉，谷子，或者both。。。
但是如果谷子需求少，那么多余的谷子就可以用来提高肉的产量，那么谷子就不用进口，故这个假设必须说明作者: rudder26 时间: 2010-8-17 21:12
其实楼主不要纠结于意思中逻辑关联是否符合常理，只要元素的关系清除就足够了 同时，做逻辑最怕就使主观想多了，楼主一纠结的话，很容易会想多。不知不觉就会想high了。作者: promiselu 时间: 2010-8-17 23:19
猪要吃谷子 对对 哈哈 但是人们对猪肉的需求增加了，所以用更多的谷子喂猪，所以谷子的用量增加导致不够了，并不一定代表买猪肉的人也要买谷子吃啊——People in Gortland who increase their consumption of meat will not radically decrease their consumption of grain. C不是很对么？ 因为人均收入和人均食肉量增长都很迅猛，所以Gortland will soon have to import either grain or meat or both.
