lawyer的话实在是太高了！不过虽然觉得说的有道理，但是如果真那么复杂，全世界能在短时间内做对的没几个人了，我觉得还是C更象ETS的思路。lawyer说呢？

6.The quality of unrefined olive oil is not actually defined in terms of acidity, yet       extensive tests have shown that the less free oleic acid an unrefined olive oil contains per liter, the higher its quality.  The proportion of free oleic acid that an olive oil         contains is an accurate measure of the oil’s acidity.                                                               

If the statements above are all true, which of the following conclusions is best supported by them?

1. When an olive oil is refined, the concentration of oleic acid in the oil is reduced.
   

   
   

2. The quality of an unrefined olive oil can be determined only by accurately measuring its acidity.
   

   
   

3. If an unrefined olive oil is intermediate in acidity between two other unrefined olive oils, it will also be intermediate between them in quality.
   

   
   

4. Free oleic acid is the only acid that unrefined olive oil contains.
   

   
   

5. People who judge the quality of unrefined olive oils actually judge those oils  by their acidity, which the judges can taste.(06/18/2004)

从另外的观点看看E: 原文起点-The quality of unrefined olive oil is not actually defined in terms of acidity.其他内容都是围绕"酸"(尽管,yet)是很好的指标(客观上),但是它没有在实际使用中应用.这样E提出结论,评审的标准是taste(主观上). 原文作为铺垫, 最后到E

A有一个Assumption:Refine以后, 酸度下降=>无法(或者不用)根据酸度,判定refine的好坏(或者变成一样品质的,这样对于unrefined的酸度就无所谓.).

但A最后用的是"Reduced", 而不是"eliminated",这样的话,其酸度还是可测的,还是可以作为评判的标准. 除非根据原文把酸度只是定义为只应用在Unrefined. ---- 是不是A与E相比太delicate

C肯定不对,因为它已经把酸度作为判定unrefine质量的标准.

没各位想得深, 第一题做错了选了D, 因为说实话1分半里我A就没看明白, 看各位一分析发现其实就是自己看完题后脑子里设想的答案, 但是绕了一层说. FAINT, 挨千刀的ETS有话不好好说

第二题赞成A, 看见这个答案一取非当时感觉就是了. 其他的也想不深了~~

lawyer1的分析有一些地方我不能苟同，我认为其第四点的翻译有误，它并不是说提炼后的FREE　ACIDITY和ACIDITY一样，而是说FREE ACIDITY是测量ACIDITY的一个精准的方法。也就是说在这两种酸之间有一种比例可以进行计算。那么我们看C选项，如果原句中的最后一句话就是我的理解的话，那么知道ACIDITY的比例就可以反推FREE ACIDITY，而这个又决定了粗品油的品质。所以如C选项所说，如果一种油其ACIDITY的含量在其他两个ACIDITY的含量中，那么它的FREE ACIDITY也一定是居中的，于是它的品质也会居中，故选C。而且我个人认为A选项完全就和题目无关，是一个不可能由理由推出的结论

不理解为什么d不对，最后一句话说the proportion of free acid is an accurate（精确的） measure of acidity,如果free acid is NOT the only acid in the unrefined olive oil,那么他怎么可能是衡量酸性的精确标准呢？

对于c，觉得和题目中第一句话矛盾，虽然后面有一个转折，但是问题说的事if the statements above all are true

觉得自己被它绕进去了，第一次作的时候选得c，这次就有了这么多疑问

对啊, C和原文第一句话The quality of unrefined olive oil is not actually defined in terms of acidity 矛盾啊!

不同意lawyer的解释，A选项里面说得是When an olive oil is refined, the concentration of oleic acid in the oil is reduced.而原文说得是free oleic acid，两者不同，所以A不对，同意选C

以下是引用vacationer在2005-9-6 23:58:00的发言：

对啊, C和原文第一句话The quality of unrefined olive oil is not actually defined in terms of acidity 矛盾啊!

我觉得应该选C。因为A中使用的是oleic acid, 而不是free oleic acid.但是C又和第一句话冲突。

有没有人解释一下。谢谢

sweetstar

up!

i prefer C to A, since A use "oleic acid"  instead of " free oleic acid" ...but the C is against the 1st sentence of the argument,

any thoughts about this? thanks
