标题: OG題.請幫幫忙(第一次pose題目)og-159,og-144,og-153
有沒有人可以幫我解釋#164.我對於ETS的解釋不是很懂......
另外#159(B)為何不是正確答案?
#144(A)及#153(E)如何解釋錯的原因?
感謝好心人的幫忙!

#164 Useful protein drugs, such as insulin , must still be administered by the cumbersome procedure of injection under the skin. If proteins are taken orally, they are digested and can not reach their target cells. Certain nonprotein drugs , however, contain chemical bonds that are not broken down by the digestive system . They can , then, be taken orally.

The statement s above most strongly support a claim that a research procedure that sucessfully accomplishes which of the following would be beneficial to users of protein drugs?
(A) Coating inslin with compounds that are broken down by target cells, whose chemical bonds are resistant to digestion.
(B) Converting into protein compounds, by procedures that work in lab.. the nonprotein drugs that resist digestion.
(C) Removing permianently from the digestive system any substances that digest proteins.
(D) Determining , in a systematic way, what enzymes and bacteria are present in the normal digestive system and whether they tend to be broken down within the body.
(E) Determining the amount of time each nonprotein drug takes to reach its target cells.

#159 Half of the subjects in an experiment---- the experimental group ----consumed large quantities of a popular artificial sweetener. Afterward, this group showed lower cognitive ability than did the other half of the subjects--- the control group--- who did not consume the sweetener. The detrimental effects were attributed to an amino acid that is one of sweetener's prinicipal constituents.
Which of the following , if true, would best support the conclusion that some ingredient of the sweetener was responsible for the expenimental results?
(B) The amino acid referred to in the conclusion is a component of all protein , some of which must be consumed for adequate nutrition.-------可以解釋為何錯?

===================================
这道题实际上是一个问题解决型，在文章中作者提到这种叫Protain Drugs由于会被消化道分解，不能到达目标细胞，因此只能注射，不能口服。题目要求找一个研究成果能有效解决这个问题。

（A)发现一种糖衣片，既包含这种药物成分，又不会中途被消化道分解，所以这项发现将能保证即使口服这种糖衣片，其中的药物成分到达目标细胞。[/face]

看了一下；本题要找出这种Amino Acid是不是原因的支持，而不是说这种Amino Acid是如何造成的原因或怎样才能避免这种不良的效果。所以判断文章的论证重点和方向很重要。如果没有记错的话，这道题的答案因该是一个它因排除型的选项，即实验之前两组的认知能力基本没有区别。由此加强服用这种Amino Acid正是造成这种效果的原因。[/face]

请问The statement s above most strongly support a claim that a research procedure that sucessfully accomplishes which of the following would be beneficial to users of protein drugs?
怎么翻译？

作者: orchidbrook 时间: 2005-4-8 05:38

请问164 （B)是什么意思？是不是“通过试验把protein转化为nonprotein",这样好像也可以解决问题。

作者: 我爱欧洲 时间: 2005-5-23 23:43
159.B项说Amino Acid包含在一种两组都会吃的蛋白质里，因此这个factor在两个组都出现，不能作为区别结果的原因。

上述强烈支持一种说法，结合下面哪一种做法一个研究过程对蛋白质药品的服用者有好处？

B是把nonprotein转化为protein。OG的解释是转化为protein就必须注射，这样更麻烦。

THANKS TO DORBEAR.

我觉得这个问题的好像是问：从上面的论述可以得出一个研究程序成功完成下列哪一个，这个研究程序就可以使protein drugs服用者受益？

这道题我觉得应该是conclusion题。即从原文的信息来获得结论，而这题不是直接问这个结论是什么，而是故意绕弯子

作者: dreamerps 时间: 2005-7-26 23:04

偶对OG中对C的解释不明白，请XDJM们帮忙分析下~~感谢~

if removing substances that digest proteins(choice C)enabled protein drugs to be taken orally,it would be at the expense of normal digestive function.

作者: xixi2004 时间: 2005-8-15 21:42

如果为了使p能被口服，而将能消化P的物质去掉，那将是以牺牲正常消化功能为代价的。

这道题的后半部分(non-p)是在混淆视听，因为问的是p user.

159.B项说Amino Acid包含在一种两组都会吃的蛋白质里，因此这个factor在两个组都出现，不能作为区别结果的原因。

159的B可以看出以上解释吗?

(B) The amino acid referred to in the conclusion is a component of all proteins, some of which must be consumed for adequate nutrition.

我的理解是: 结论中提到的氨基酸是所有蛋白质的一种成分, 一些蛋白质可以带来营养.

我的理解有误?

另外, 麻烦XDJM帮我看看OG对B的解释:

Choice B indicates that, outside of the experiment, both groups consume the amino acid. If relatively small quantities are involved, the conclusion is unaffected; otherwise it is weakened.

真的看不懂. 个人觉得B只是陈述了一下氨基酸的背景. 似乎和做实验无关, 所以根本无法理解"the conclusion is unaffected; otherwise it is weakened".

请大家帮忙看看!!

up!

作者: cynthia704 时间: 2005-10-5 11:11
If relatively small quantities are involved,the conclusion is unaffected;otherwise it is weakened. 選項B中如果只有相當少量的amino acid(在proteins consumed for adequate nutrition中)被攝取，那麼結論是不受影響的，反之如果量很大的話，結論就會被weaken. 這是個人對於這段話的看法

,不知道是否正確，請大家幫忙一起討論看看

作者: snowjing 时间: 2005-10-6 10:26

谢谢cynthia704.

再问一句:

显然这里的 quantities involved是outside of the experiment, 那怎么会对experiment result有影响呢?

作者: cynthia704 时间: 2005-10-6 11:39
實驗的中心內容是"amino acid對cognitive abilities的影響"，所控制的因素在於"被實驗者攝取amino acid的量"，如果額外攝取的amino acid相當大量，應該是會對實驗結果造成影響的唷.... 我是這樣想的，snowjing不知道你覺得ok嗎?

我最近也深深爲CR所苦呀

作者: snowjing 时间: 2005-10-7 00:53

我觉得OG解释: Choice B indicates that, outside of the experiment, both groups consume the amino acid. If relatively small quantities are involved, the conclusion is unaffected; otherwise it is weakened. 后半句若是放在实验中, 如你所说, 我是可以理解. 但是, 它前面又加了一句 outside of the experiment, 真令人费解(还是不明白).

幸好,答案还是蛮简单的. 就这样放过B了?

作者: snowjing 时间: 2005-10-7 00:56

MM在CD上的最早两篇文章都帮我解题了, 实在感激.

CR是GMAT中最费脑细胞的啦, 慢慢来. 听哪位NN曾说过, 逻辑在于理解理解, 再理解!

作者: cynthia704 时间: 2005-10-8 11:22

呵呵~~被MM發現了..你真是細心... 正好在看CD的時候發現你的帖子，覺得有人一起努力真是感動...心裡就覺得一定要回...大家一起激盪腦力...

對於OG這邊的解釋我的理解是，實驗中有兩組人"consume large quantities"和"did't consume "，而只有"consume large quantities"這組有lower cognitive abilities的現象，是造成結論"some ingredient(amino acid) of the sweetener was responsible for the experiment results-- lower cognitive abilities."的主要原因......

如果除了實驗中提供的amino acid以外，兩組人各自都還是攝取了相當量的amino acid，那麼實驗本身假設的前提就不存在了...因此對實驗結果帶來影響....

我想你的想法和我的中間一定有gap，偏偏我文字的表達能力實在不夠，沒有辦法清楚表現我的意思，真是汗顏~~~ ...btw，謝謝你的鼓勵唷....

作者: coolhany 时间: 2005-12-19 14:21

我对B的想法是：amino acid 既然是a component of all proteins，而且some of which must be consumed for adequate nutrition，那么人都会摄入amino acid ，无论是否有这个实验。换句话说就是the experimental group和the control group都摄入了amino acid 。既然如此就不能说明amino acid 在起作用了。而且这也和OG的解释吻合了，Choice B indicates that, outside of the experiment, both groups consume the amino acid. If relatively small quantities are involved, the conclusion is unaffected; otherwise it is weakened.如果摄入量多，你也不能确定是从其它渠道摄入的还是从sweetener中摄入的amino acid 影响了小孩的cognitive abilities 。

请NN指教
