标题: GWD-10-Q30:GWD-2-17 [打印本页] 作者: hanyichen 时间: 2012-6-29 22:28 标题: GWD-10-Q30:GWD-2-17 GWD-10-Q30:GWD-2-17 整理出的思路 综合外网的解释 我觉得很对。 Thequality of unrefined olive oil is not actually defined in terms of acidity, yetextensive tests have shown that the less free oleic acid an unrefined olive oilcontains per liter, the higher its quality. The proportion of free oleic acid that an olive oil contains is anaccurate measure of the oil’s acidity.
If thestatements above are all true, which of the following conclusions is bestsupported by them?
A. When an olive oil is refined, theconcentration of oleic acid in the oil is reduced. B. The quality of an unrefined olive oil can bedetermined only by accurately measuring its acidity. C. If an unrefined olive oil is intermediate inacidity between two other unrefined olive oils, it will also be intermediatebetween them in quality. D. Free oleic acid is the only acid thatunrefined olive oil contains. E. People who judge the quality of unrefinedolive oils actually judge those oils by their acidity, which the judges cantaste.
这是思路图： Acidity 不等于 Quality free o o 与 quality 成反比 结论： free o o 是衡量 可以衡量acidity 选C： 意思为，在ACIDITY上， 如果一个UOO 在其他两个UOO 中间， 那么在quality上也是 一个UOO 在其他两个UOO 中间。 只有3个UOO 在一起 才能看出 ACIDITY 和 QUALITY 的关系。他们的关系不知道 但是肯定是有关系的
