※ 引述《denizee3 (妮 快疯了!!!)》之铭言： : 56. Gortland has 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 per capita income continues to rise， : whereas domestic grain production will not increase， : Gortland will soon have to import either grain or meat or both． : 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 把NOT去掉,意思是这国家的种稻面机会大量下降,符合原文,无法反驳 : (B) The population of Gortland has remained relatively constant during : the country's years of growing prosperity. 人口总数的变动不是题目重点,纵使人口下降,但每人平均食肉量大幅增加,也无法反驳 : (C) The per capita consumption of meat in Gortland is roughly the same : across all income levels． 各阶层间每人食肉量也不是重点,纵使各阶层差异大,但总食肉量还是大增,也无法反驳 : (D) In Gortland, neither meat nor grain is subject to government price : controls． 这选项....价格稳定与否不是重点 : (E) People in Gortland who increase their consumption of meat will not : radically decrease their consumption of grain． 去掉NOT,国民增加食肉量同时,会大幅下降实用谷物量,所以并非会造成谷物不够需进口 之情形发生,同时被减少的谷物又能拿来饲养产生更多肉品,所以肉品也未必会短缺 固反驳原文!!! 是反驳的反驳法 : 答案是E. : 我看了後面的解释..感觉好像稍微懂为什麽是E但是又好像没有完全懂 : 是否请各位贤人能够帮忙解释一下呢? : 感激不尽! <(__ __)> --
