标题: 讨论一道重要题！

In the past, every ten-percentage-point increase in cigarette prices in the country of Coponia has decreased per capita sales of cigarettes by four percent. Coponia is about to raise taxes on cigarettes by 9 cents per pack. The average price of cigarettes in Coponia is and has been for more than a year 90 cents per pack. So the tax hike stands an excellent chance of reducing per capita sales of cigarettes by four percent.
Which of the following is an assumption on which the argument depends?
A.Tobacco companies are unlikely to reduce their profit per pack of cigarettes to avoid an increase in the cost per pack to consumers in Coponia.
B.Previous increases in cigarette prices in Coponia have generally been due to increases in taxes on cigarettes.
C.Any decrease in per capita sales of cigarettes in Coponia will result mainly from an increase in the number of people who quit smoking entirely.
D.At present, the price of a pack of cigarettes in Coponia includes taxes that amount to less than ten percent of the total selling price.
E.The number of people in Coponia who smoke cigarettes has remained relatively constant for the past several years.

此题的答案是D吗？？

此题的重点在于对stands的理解，是“阻碍”还是“维持”？

选A吧

选D.

应该是选D把，说明了TAX是含在PRICE里的，所以如果提高TAX9美分，价格也上涨9美分，刚好是原来价格的10%

STAND是支持价格上涨引起销售亮下降的意思把

请问题目给的答案是什么?

我认为选A,通过建桥:

Coponia is about to raise taxes on cigarettes by 9 cents per pack. The average price of cigarettes in Coponia is and has been for more than a year 90 cents per pack.

推出前提:CO将对CI增加10%的税收

So the tax hike stands an excellent chance of reducing per capita sales of cigarettes by four percent.
结论:税收的增长使CI的销售减少4%

所以题目逻辑是:税收增加10%=>CI的销售减少4%

文中给出信息是:In the past, every ten-percentage-point increase in cigarette prices in the country of Coponia has decreased per capita sales of cigarettes by four percent 价格增长10%=>CI销售减少4%

通过建桥可得出税收的增加=>价格增长,即A:

A.Tobacco companies are unlikely to reduce their profit per pack of cigarettes to avoid an increase in the cost per pack to consumers in Coponia

支持楼上的分析，price=cost+profit, 选A

作者: cjyc1 时间: 2007-6-10 02:06

没有答案啊，但是你对stands的理解，是“阻碍”还是“维持”？如果是“维持”就是选A，是阻碍则选D吧！

你们的理解呢？？

"sb stands a chance of doing sth" is an idiom that means sb has a chance to succeed in doing sth or has the probability of being successful in doing sth.

The below URL is for your reference:

So obviously choice A is the correct answer.

多谢，哥们的知识面真全面阿

选Ａ，对于assumption , 用not +weaken 的方法去看，具体来说此累题目一般正确答案都会用否定句的形式（除了一些个别的），看到否定句先把否定词盖住，在看剩下的句子是不是起削弱作用，比如本题　中Ａ，先去掉unlikely，于是变成了Tobacco companies are reduce their profit per pack of cigarettes to avoid an increase in the cost per pack to consumers in Coponia.可以清楚的看到Tobacco companies为了不让他的香烟的价格增加，所以将其成本减少，　导致价格不变，所以税收的增加并不能让人均香烟的消费水平减少，　Ａ去掉否定词起ＷＥＡＫＥＮ　的作用，　所以选Ａ

首先，stand 没有“阻碍”的意思

表达上述意思，你只能说 stand in the way of something

另外，如8楼所说，这里stand 也不是“维持”的意思

不过，我想这个词，大概不是题目的重点，，，

这道题的本意，是看你能不能注意到，政府增加9分钱的税不一定等于香烟的价钱增加9分钱

所以一个隐含前提是，加税之后，烟草商不能改变现有成本利润额

所以选A

选项D 完全属于无关选项，不管你怎么理解stand

题设说的是香烟价格变动导致人均消费变动，与现有税率完全无关，

选项D 不过是把题设中的几个词抽出来，组合成一句话而已，与题目逻辑无关

作者: starbird 时间: 2007-6-12 08:27

补充，

你大概把D 的意思理解错了，D 说的是，Coponia 现在每包香烟含不到售价10%的税

从题目中可以退出现在的tax低于10%，但是对结论不产生影响。而a中，明确提出了生产商不会降价，因此价格一定上涨，sales一定下降。
