逻辑-GWD5-Q3 (GWD24中的GWD-TN-3)
[font=Tahoma][size=9.5pt][/size][/font][font=Tahoma][size=9.5pt]The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia.
Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed.
However, recent statistics show a drop in the number of television assemblers in Borodia.
Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.[/size][/font]
[font=Tahoma][size=9.5pt][/size][/font]
[font=Tahoma][size=9.5pt]Which of the following is an assumption on which the argument depends?[/size][/font]
[font=Tahoma][size=9.5pt][/size][/font]
[font=Tahoma][size=9.5pt]A. [/size][/font][font=Tahoma][size=9.5pt]The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.[/size][/font]
[font=Tahoma][size=9.5pt]B. [/size][/font][font=Tahoma][size=9.5pt]Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.[/size][/font]
[font=Tahoma][size=9.5pt]C. [/size][/font][font=Tahoma][size=9.5pt]The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.[/size][/font]
[font=Tahoma][size=9.5pt]D. [/size][/font][font=Tahoma][size=9.5pt]The number of televisions assembled annually in Vernland has increased significantly during the past three years.[/size][/font]
[font=Tahoma][size=9.5pt]E. The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years.[/size][/font]
[font=Tahoma][size=9.5pt]正确答案是C,我选了D[/size][/font]
[font=Tahoma][size=9.5pt]这道题目,我看了几遍都觉得脑子里一团糨糊.XDF老师说过,碰到这种题目,脑子里面应该有一个式子可以列出来,跟式子的变量相关的,就是正确答案...但是这道题目的关系太复杂啦,我推不出来...[/size][/font]
[font=Tahoma][size=9.5pt]想问一下,碰到这样的题目,解题的思路是什么样的呢?这道题目正确的解题思路又是什么呢?[/size][/font] 题干说 Borodia 制造电视的工人人数减少了，因而得到结论 Borodia 从 Vernland 进口的电视增加了。这里有个关键，工人人数减少了，那就等于出产的电视数目也减少了么？C 就是补充这点。 [quote]原帖由 [i]Asrgbf[/i] 于 2009-5-28 21:33 发表 [url=http://bbs.taisha.org/redirect.php?goto=findpost&pid=14403971&ptid=1247444][img]http://bbs.taisha.org/images/common/back.gif[/img][/url]
题干说 Borodia 制造电视的工人人数减少了，因而得到结论 Borodia 从 Vernland 进口的电视增加了。这里有个关键，工人人数减少了，那就等于出产的电视数目也减少了么？C 就是补充这点。 [/quote]
就是说,"工人的人数减少了,但是在B地制造每台电视机的时间并没有减少,由此得出B地出产电视机的总体数量减少了,因而在B地销售的数量不变的情况下,可以得出结论是从V地进口的数量多了." 是这样推理的吗? 要分清楚什么是 assumption，什么是推理的一部份。
题干说 Borodia 工人减少了，因此电视机生产也减少了。这里面的 assumption 就是：每个工人生产的电视机数目没有增加（即每个工人制造一个电视机的时间没有减少），不然虽然人数减少，生产数量却未必减少。结论就不成立了。 明白了,谢谢A大大教导 不错 谢谢
