谢谢大家的耐心讲解。^-^

我认为18题的E应该只是个前提而不能加强结论。

但是同样A也起不到加强结论的作用，只是对公式的另外一种理解。

疑惑了。到底哪个是正确答案啊。。。。

请哪个告诉我大全-6-18答案到底是A还是E. 谢谢.

大全-6-19.      In January there was a large drop in the number of new houses sold, because interest rates for mortgages were falling and many consumers were waiting to see how low the rates would go. This large sales drop was accompanied by a sharp rise in the average price of new houses sold.

原文说 房子销售量下降，伴随着房子平均售价的上升。

(A) Sales of higher-priced houses were unaffected by the sales drop because their purchasers have fewer constraints limiting the total amount they pay.

choice A, 高价房销售并未受影响。

销售量和房子的平均售价有关系么？？？

fk！！！ 今天下午看了10几道逻辑，基本上都不明白

崩溃了......

I think it's a perfect explanation, clear and convincing. definitely the answer should be E

以下是引用albert在2003-9-12 21:53:00的发言：

Hi emonee,

I don't quite agree with your explanation..I think E is the answer, below is my reason.

first, we should know what is the evidence and conclusion of the argument.
evidence:
1. value of product= quality/price
2. the higher the value, the better will be its competitive position.
conclusion: either increasing the quality or decreasing the price, customer will be likely to choose the product.

In the passage, we notice a GAP between evidence and conclusion: value of product and customer's choosing the product..We can not safely conclude that the higher the value, the more likely that customers will choose the product UNLESS we know that customer can identify the value correctly. In other words, IF customers can't make sure which product has higher value, how can we conclude that customers will surely choose the product with higher value?

a is incorrect because it simply repeat the meaning of evidence 1..without mentioning the relation between evidence and conclusion, it can not support the conclusion..

e is correct because it fill the GAP between evidence and conclusion..without E, the conclusion can not safey be drew.
"the actual quality of the product" in choice is the same meaning of "the value of the product".

my two cents.

good luck!

这题偶恰好明白了。因为有钱人一般并不在乎按揭的利率高低，所以在平民百姓都不买，在等按揭利率进一步降低的时候，有钱人没有减少买房，也就是说这段时间卖出去的都是贵房咯，于是平均售价自然升高。

大大太牛了，完全同意“取非法”的观点。下面是我自己的推导过程，希望对大家有帮助。

如果A不成立，也就是说同时提高price和quality必然改变competitive position，那么也就能推理出，competitive position和price，quality之间没有ratio的关系，那么原来的整个推理的前提都不成立了。其实A是题干推理的前两个条件的推论，value = quality/price, 和competitive position正比于value，推出competitive position正比于quality/price，进而推出A。就如同“所有的马都跑得快”能够推出“白马也跑得快”一样，“白马也跑得快”反过来也能加强“所有的马都跑得快”的结论。所以A也能够加强题干推理的前两个条件，这样自然也就加强了整个推理的结论。

E选项的问题在于引入了无关topic，perception和actual quality都是跟原题目无关的内容，E选项扩大了论述的外延。之前有大大提到原题目的推论有gap，gap顶多就是competitive position的提高不能必然导致consumer will select that product rather than a competing one。因为根据前两句话提供的条件，either increasing the quality or lowering the price必然导致value的增加，也导致competitive position的提高。gap只存在于competitive position的提高和顾客更乐于选择这种商品之间。而E也不能弥补这个gap。事实上，个人觉得，这根本就没有gap，competitive position的含义应该就是顾客更多的选择这种商品。

1。 E is wrong because it just explain unilateral reason---quality.
     From the question:
     Bigger Premise:The higher the value of a product, the better will be its competitive position.
     Small Premise:The value of a product is determined by the ratio of its quality to its price.
     Quality cannot make the value of product by itself, so it is unilateral.
     B,C,D are weaken.
     A is correct answer. You can use 取非法
