29. The number of people diagnosed as having a certain intestinal disease has dropped significantly in a rural county this year, as compared to last year, Health officials attribute this decrease entirely to improved sanitary conditions at water-treatment plants, which made for cleaner water this year and thus reduced the incidence of the disease.
Which of the following, if true, would most seriously weaken the health officials’ explanation for the lower incidence of the disease?
(A) Many new water-treatment plants have been built in the last five years in the rural county.
(B) Bottled spring water has not been consumed in significantly different quantities by people diagnosed as having the intestinal disease, as compared to people who did not contract the disease.
(C) Because of a new diagnostic technique, many people who until this year would have been diagnosed as having the intestinal disease are now correctly diagnosed as suffering from intestinal ulcers.
(D) Because of medical advances this year, far fewer people who contract the intestinal disease will develop severe cases of the disease.
(E) The water in the rural county was brought up to the sanitary standards of the water in neighboring counties ten years ago.

问题:
1) A也可以理解为削弱? 既然5年前水的条件就改善了, 说明去年和今年,水的条件是相同的, 但结果不同, 说明有别的因素?
2) C的逻辑角度可以理解, 但在理解题意上有些不明白的地方. intestinal ulcers.难道不属于intestinal disease 嘛? C只是说明新技术更准确的判断出是哪种肠道疾病而异.

(A) Many new water-treatment plants have been built in the last five years in the rural county.
only introduce to readers that there are many new water treatment plants
BUT did not mention anything about the sanitary conditions there, which is the key to weakend the arguments.

and C provides us with an alternative explanation of why increased in sanitary conditions at water plants will not help to decrease the intestinal dieases.

谢谢. A我懂了.C还是有些不明白, intestinal ulcers.和 intestinal disease 的概念不是从属关系嘛? 是否只是个翻译理解的不同? 肠道溃烂不属于肠道疾病嘛? 是否说检查出是溃烂了, 这部分人就不算作是得肠道病的人了?

上文说：a certain intestinal disease，根据它的意思：这种病好像是有细菌引起的肠道传染病，肠溃疡是不一样的。

个人理解。

Intestinal ulcers and is one type of intestinal dieases, but here you dont really have to know the difference between these two.

请教：D为什么不对？

携隐 · 发表于 2004-9-18 09:27:00

文章讨论的是得不得病,D讨论的却是得病后程度会不会加深,跟文章无关.

我觉得你有这个问题，是因为没有把C读透，C说

Because of a new diagnostic technique, many people who until this year would have been diagnosed as having the intestinal disease are now correctly diagnosed as suffering from intestinal ulcers

很明显的C告诉你这两种病现在是不一样的，不管他概念上是不是从属关系。

当头棒喝！

我经常就是盯住几个中心词就卡在那儿了，这句话提醒了我应当是从整体上看句子所要表达的意义。谢谢espirit。

ince A supports the view that sanitary conditions have been improving, it tends to support the officials’ explanation.

og的还是认为过去5年卫生条件一直在提高，所以认为是支持而不是反对？

不明白，如此解释应该是反对？

nn帮忙！着急！
