请各位NN们指点。。54.动物过敏 的C选项为什么不对？？
People who have spent a lot of time in contact with animals often develop animal-induced allergies, some of them quite serious. In a survey of current employees in major zoos, about 30 percent had animal-induced allergies. Based on this sample, experts conclude that among members of the general population who have spent a similarly large amount of time in close contact with animals, the percentage with animal-induced allergies is not 30 percent but substantially more.
Which of the following, if true, provides the strongest grounds for the experts’ conclusion?

A.    A zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation.
B.    A zoo employee is more likely than a person in the general population to keep one or more animal pets at home
C.    The percentage of the general population whose level of exposure to animals matches that of a zoo employee is quite small.
D.    Exposure to domestic pets is, on the whole, less likely to cause animal-induced allergy than exposure to many of the animals kept in zoos.
E.    Zoo employees seldom wear protective gear when they handle animals in their care.

我觉得如果是assumptiion, 就应该改选b. 因为如果 developed country 石油用量大量削减，然后整体石油会上升，就有可能compensate developing country的石油用量的上升。

1. developing countries undergo a dramatically increase in economy, 然后讲oil 的使用会大量上升，而发达国家使用量没什么变化，而且今后几年石油的全球开采量只是moderately 上升 结论是会有短期的石油shortage 问的是weaken 还是assumption 忘记了 不过两个问法做 法一样的 有两个选项满搞的：

a. 经济发展不会导致寻找替代资源 b.发达国家在将来的那段时间内将不会greatly reduce 他们的石油用量

我觉得这两个选项都有削弱的作用，应该选哪个呢？谢谢~~盼回答

请问这道题的答案是哪个？ 我怎么觉得都没有答案呢。c是削弱啊，结论是zoo employee-》great population, 但是选项说great population中和zoo employee像的很少，所以削弱啊。

我试着回答一下吧，这题是个explanation题，discrepancy在于人们常识性地认为在动物园里接触动物容易患过敏症，但是出人意料的是动物园以外接触动物的工作者里患过敏症的人的比例更高。

我觉得C选项并没有解释这个discrepancy。题干内容是比较在动物园工作的人和在外面同样程度接触动物的人患过敏症的比例，而C说的却是患过敏症的程度不同。这个应该是典型的偷换概念。

打个比方说，我说上GWD的课的同学上700分的比例肯定比只上CD的复习时间相同的同学比例高，但是事实上只使用CD论坛学习的人上700分的比例超过了只上GWD的同学。问为什么有这种现象，有人就说了，上GWD的同学760分以上的比例较低。——这个明显就不能解释discrepancy了。说得可能啰嗦了点，呵呵

JJ的第52题是不是有点问题啊?小车比大车发生的事故更严重还可以通过坐小车减少伤害??

-- by 会员 liaogaoqian (2009/12/1 17:19:26)

我也同意， 好像后面的问题 应该是大车吧？

请NN或者考过的同学上来确认一下啊。。。

19题那个雪橇的那个题为啥不是b呢？因为我觉得b也能undermine那个fact

-- by 会员 treepple (2009/11/30 12:16:29)

我个人之见：

我认为是无关。

退一步说，即使有关，不戴安全头盔之类的，那文章也没说wood的滑板带了安全头盔了，不管使用所料雪橇还是木质雪橇都没带安全头盔，属于各打50大阪，不能削弱啊。

人们只知道S的鸡肉可能会感染病毒， 而别的鸡肉不会（人认为）
实际上s的鸡肉会在超市里传染没感染s的鸡肉
然后就削弱了，实际上这种病毒还是会对人有影响

-- by 会员 lovesasa0820 (2009/11/29 14:54:56)

这个题我也有点晕。

专家说这有病毒S的肌肉对人没影响，（就是人可以吃。）

(削弱的方向应该是对人有影响，)

这个选项s病毒的肉会在超市传染没有S病毒的肉。 既然专家都说了，有S病毒的肉不会影响人。 那么肉传染还是不传染到没病毒的肉都没关系啊。。。

所以我认为没有削弱啊。。。

请再详细解释一下。。。

谢谢

渔民抓大鱼，放小鱼，普遍观点是：为了维持鱼群的生态平衡。有个实验：抓每个GENERATION的大鱼，只留10%的小鱼，一直抓到7个GENERATION，发现这种鱼的数量大量减少。结论：实验结果表明抓大鱼，放小鱼，不利鱼群生态。问题：哪项可以WEAKEN这个实验的观点。
这题不是很明白~

-- by 会员 htsea8 (2009/11/29 15:05:04)

题目问的是削弱--求解的方向应该是 抓大鱼方小雨有利于鱼群生态。

实验中， 我们就做一个少一点的generation , 2代吧， 只抓只抓爷爷和儿子这两代大鱼，那么爷爷以上的gernation 和孙子的一下的generation 还继续繁殖， 不会影响鱼群的生态平衡。

渔民是把所有的每一代的大鱼都抓走了，谁来繁殖啊，所以鱼群就减少了。 我认为这个答案渔民抓大鱼并不分哪一代，应该是削弱了，说明这个实验抓大鱼方小雨有利于鱼群生态。

46. 维生素D
V1 说现在很多人没有缺维生素D的疾病，但是很多人维生素却不足
应该选A
说摄入标准定的太高，因为当时定的标准是为了防止缺维生素D疾病的发生 Answer Warranty By ONGHAT

这道题目没怎么想的明白,哪位NN给讲讲啊,是不是可以理解为不得病的标准远远还是要低于设定的标准,然后定一个高标准让人们多吃,所以实际上超过了不得病的标准,但还是缺乏...不知道我这么说一通说明白没..

-- by 会员 liaogaoqian (2009/11/30 17:25:34)

我不是NN， 我也这样理解的。

请NN路过扫一眼。。。

还有一道
40. 潜意识

Psychologists think…will power和下意识的一个关系；反对者认为will power怎样怎样，有提到一个单词involuntary. 问assumption.选：psychologists 不认为某样事情是involuntary的。此题不是难在逻辑本身，是太抽象了，不容易读懂。

大家说，它想说什么呢。。。。。。。

-- by 会员 skyice九九 (2009/11/29 15:35:09)

我猜是：

心理学家认为意志力和下意识是存在xxx样的联系的（可能是谁能导致谁之类的），而有人反对说意志力是自动形成之类的，两者之间没有必然关联。

问假设（可能是问心理学家的假设？）（如果问反对者的假设，那么前面的观点就可能是相反的）

所以，选了 心理学家不认为意志力是自动形成的。

乱猜啊

这个题是哪个版本的40啊， 我怎么没找到呢，最近版本是多少题？
