标题: 一个国外的GMAT 论坛。里面好像有新题

一个国外的GMAT 论坛。里面好像有新题 www.beatthegmat.com

In recent years, unions have begun to include in their demands at the
collective bargaining table requests for contract provisions which
give labor an active voice in determining the goals of a corporation.
Although it cannot be denied that labor leaders are highly skilled
administrators, it must be recognized that their primary loyalty is
and must remain to their membership, not to the corporation. Thus,
labor participation in corporate management decisions makes about as
much sense as __________.
Which of the following represents the best continuation of the
passage?
A. allowing inmates to make decisions about prison security
B. a senior field officer asking the advice of a junior officer on a
question of tactics
C. a university's asking the opinion of the student body on the
scheduling of courses
D. Chicago's mayor inviting the state legislators for a ride on the
city's subway system
E. the members of a church congregation discussing theology with the
minister

Land Management Specialist:
"Building the Glenn Canyon dam on the Colorado river caused unforeseen
environmental effects. One of these is that, by preventing annual
floods, the dam prevents the river from stirring up sediments
collected on the river bottom and depositing them high on the banks of
the river. The deposited sediments are needed to create and maintain
sandbars, which form natural habitats for native fish. By releasing
water from the dam annually, we will flood the river and thus recreate
the sandbars normally found below the dam."

Which of the following must be true if the prediction of the land
management specialist above is also to prove true?
A. There are no other effects of the dam which will prevent the native
fish of the river from using the new sandbars below the dam.

B. The flood caused by massively releasing water from the dam will be
like a natural flood in every major respect.

C. The size of a sandbar on a river always stays the same or increases
after a flood.

D. Any other dams upriver from the Glen Canyon dam must also release
enough water to cause a flood in order for the flood from the Glen
Canyon dam to be successful.

E The dam does not prevent the flow of sediments from upriver needed
to replenish the sediments that inevitably wash downstream over time.

Can someone please explain the answers to these questions?

另外请各位解答一下上面2题

作者: mgq 时间: 2008-8-6 11:31

In 1980, a Danish ten-øre coin minted in 1747 was sold at auction for $8,000. Eleanor Bixby owns another Danish ten-øre coin minted in 1747. When she puts it on the market next week, it will fetch a price over $18,000.

Which of the following, if true, would most weaken the conclusion drawn above?

(A) Since 1980, the average price for rare coins has increased by over 150 percent.
(B) There are only four coins like the one in question in the entire world.
(C) Since 1980, the consumer price index has risen by over 150 percent.
(D) In 1986, a previously unknown cache of one hundred coins just like the one in question was found.
(E) Thirty prominent, wealthy coin collectors are expected to bid for Bixby’s coin.

这个题比较怪，论坛上的答案是D 但是D明显就超出结论范围了。其他的答案也是。请各位解答

作者: jesuiscjj 时间: 2008-8-6 13:42

第二题选E

第二题有些犹豫，recreate这应该是关键词，必须证明dam不把用来recreate的sediment阻挡住就行了。

第三题D正确，因为当时有同样的钱币被发掘，原来只有两块，现在多了一百块，就不那么值钱了。

1楼，我选A和E

我的思路：

第1题：工会和公司管理层做企业决定的关系就如同囚犯和制定监狱治安条款的微妙关系是同一种pattern. 题目中最关键的一句是 it must be recognized that their primary loyalty is and must remain to their membership, not to the corporation. 也就是说工会和企业的利益是对立的，而工会领导人必须选择对立的2个立场中的一个。

第2题：题目是must be true的题型，也就是“阅读理解”，即根据题干信息顺着理解来选答案，我选E，因为其他选项的结论都不能根据题干中提供信息得出来

4楼，我也选D

我的思路：weaken题，题中的argument是说预测同一种古董COIN现在比1980年时更值钱。选项中ABCE都表明这种预测可能是对的，只有D中情况表明这种coin可能因为1986时市场供给增加了，而需求可能没变，所以价格反而会跌。

my 2 cents, welcome more opinions and discussions. :-)

请问ls第一题中的Although it cannot be denied that labor leaders are highly skilled
administrators如何对应，难道说也要赞美囚犯一下不成吗？

第二题有些想假定题的意思，如果选B，题干怎么会正确，我把sediment都挡住了，如何recreat，in every major respect明显是限定词了，怎么需要must be true

作者: mgq 时间: 2008-8-6 14:03

但结论是When she puts it on the market next week, it will fetch a price over $18,000.

D是1980年的next week 很明显超出了范围

作者: natalietong 时间: 2008-8-6 14:05

第一题我选C 理由：原文说工会对公司决策的作用。但工会毕竟代表工人利益。选项中的大学就像是公司，学生代表起的作用就像是工会，毕竟代表学生利益

第二题我选E 理由: 原文结论说
dam不好，理由是dam 一年只能放水一次，造成一次flood, 这样会导致dam 下部sidebar的囤积。而在建dam以前，一年多次的flood，可以将河水的淤泥stir up在岸边囤积。总的说来就是有泥就有sidebar。只是囤积地点不同。选E是用无因无果。如果dam能够滤掉淤泥的话，就不会造成放水时sidebar在底部的囤积。

第三题只能选啦，1980年值8000，现在该值18000，削弱它，找因果推理。根据供需理论，东西多了价格就讲了，所以D解决了这个问题。而且就发掘了100枚，一定程度上稀世了这种硬币的数量，也降低了相对价值。

作者: mgq 时间: 2008-8-6 14:06

对不起说错了D 是1986年发现明显超出条件所给信息的范围

作者: mgq 时间: 2008-8-6 14:07
所以我就得D是最好的答案，但是并不正确

作者: jesuiscjj 时间: 2008-8-6 14:13
第一题选C是不正确的，学生和学校的关系搞错了，正确的应该是学校是老板，学生是顾客，学校是为学生服务的，学生没有义务为学校做出贡献，而原题中labor明显是为公司服务的

作者: earlscourt 时间: 2008-8-6 14:15

第2题，我改变选择，E是对的。

第1题，我认为不用把highly skilled作为一个必须对应的因素来考虑。因为以although引导的句子，它的意思核心是it must be recognized....,而although引导的分句只是为后面的转折起铺垫作用。

4楼的题，In 1980, a Danish ten-øre coin minted in 1747 was sold at auction for $8,000，因为是was，所以1980肯定是过去的时间点了。

When she puts it on the market next week, it will fetch a price over $18,000.
will fetch是将来时。

所以题目implied的时间是现在，而不是1980。

第二题那个论坛上的答案也是倾向于E 再来一题。

The only purpose for which a particular type of tape is needed is to hold certain surgical" wounds closed for ten days—the maximum time such wounds need tape. Newtape is a,new brand of this type of tape. Newtape's salespeople claim that Newtape will improve healing because Newtape adheres twice as s long as the currently used tape does.

Which of the following statements, if true, would most seriously call into question the claim made by Newtape's salespeople?

(A) Most surgical wounds take about ten days to heal.
(B) Most surgical tape is purchased by hospitals and clinics rather than by individual surgeons.
(C) The currently used tape's adhesiveness is more than sufficient to hold wounds closed for ten days.
(D) Neither Newtape nor the currently used tape adheres well to skin that has not been cleaned.
(E) Newtape's adhesion to skin that has been coated with a special chemical preparation is only half as good as the currently used tape's adhesion to such coated skin.
这题我在C E 之间考虑倾向于C。E似乎扯得有点远：a special chemical preparation is only half as good as the currently used在原文没有提及

作者: earlscourt 时间: 2008-8-6 14:38

呵呵，请问LS第1题有正确答案吗？

14楼的题我也选C

再来一题

Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton on the world market. By contrast, the price of soybeans has long remained stable. Knowing that cotton plants mature quickly, many soybean growers in Ortovia plan to cease growing soybeans and begin raising cotton instead, thereby taking advantage of the high price of cotton to increase their income significantly,
at least over the next several years.

Which of the following, if true, most seriously weakens the plan’s chances for success?

A. The cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb.

B. Tests of a newly developed, inexpensive pesticide have shown it to be both environmentally safe and effective against the insects that have infested cotton crops.

C. In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.

D. Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.

E. The species of insect that has infested cotton plants has never been known to attack soybean plants.

这一题我用排除法：由于原文是要weaken the plan that the gower's income will increase,因此必定会有影响income的元素而且和cotton有关

A 提及到cost irrelevent

B 这个应该是support吧

C 无关吧（原文信息中无法推断出过去的信息）

D明显会影响收入 correct

E无关

作者: jesuiscjj 时间: 2008-8-6 15:11

20楼我选C

推理过程是这样的，虫害--棉花产量少，价格提高--收入显著增加（但原文没告诉是否收入真的增加了）

明显在最后一步少了一个条件，就是需求量，只要攻击这点就行了，说他没需求，空有高价格也没用

另外In the past several years正是Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton on the world market. 的这段时间，正因为过去的被否定了，所以对将来才产生疑问。

再来

Serious novelists start writing because of a desire to create a work of art and recognize as great literature the works of other novelists who achieve this goal. As a consequence, when a novel becomes a best-seller, the authors of other novels conclude that the best-seller is not truly great literature.

The explanation offered above for the view authors hold of best-sellers assumes that

A work on a novel that the author hopes will be regarded as great literature must be undertaken in solitude

B serious novelists tend not to view as great literature a novel produced by an author whose success they envy

C a novelist can produce a best-seller without having already produced great literature

D serious novelists believe that those novelists who produce best-sellers must not have aimed at producing a work of art

E the claim of a novel to status as great literature cannot be evaluated by individuals who are not themselves serious novelists
似曾相识吧 GWD有一道类似的题目不过内容变了

明显在最后一步少了一个条件，就是需求量，只要攻击这点就行了，说他没需求，空有高价格也没用

结论是说要增加收入。问题是要削弱结论。条件是因为虫害导致棉花价格升高继而导致了O 国家的农民要种植棉花赚钱。C说某个杀虫剂可以控制虫害，这样棉花的产量不就上去了？那价格还会涨吗？

而且文章也没有说需求啊。

你看错了，你说的选项是B

是要削弱结论或者从前提推出结论的过程，明显者各过程存在漏洞，因为原题中没有提过会有高收入，只说有搞价格，所以如果过去的时间里，搞价格没有带动高需求，也就没有了高收入，那些农民是根据过去到现在的事实判断的，这样一来，他们的判断不正确，因此采取措施效果也就不一定好了

Although most people know that the exercise is good for the body, few realize the extent to which it is valuable to the mind. The blood circulates more rapidly after the physical exertion, thus allowing all of the body's organs to operate more efficiently. This increased activity enables brain to receive more oxygen, thereby creating a higher capacity for concentration.

The main point in the argument above is that

1. the greater the amount of oxygen brain receives, the better it functions.

2. Exercise is a mental as well as physical activity.

3. Exercise helps the brain more than it does the rest of the body.

4. people can greatly improve their powers of concentration by exercising more often.

5.exercise serves more than one purpose.

A certain drug, when taken by patients with high blood pressures, was found to lower the blood pressure to high-normal levels, or from an average of 30 percent to an average of 10 percent above normal. However a survey of patients with normal blood pressures found that almost 80 percent exercised atleast 5 days per week for 30 minutes and maintained a normal blood pressure.
Therefore, the drug is not as affective in reducing blood pressure in patients with high blood pressure as is exercise. The validity of the above conclusion depends on the truth of which of the following ?

A.None of the patients with high blood pressure exercise regularly.
B. No patient with high blood pressure successfully achieved below-normal levels with drug alone.
C. Patients with normal blood-pressure maintained healthy diets for the duration of the study.
D. Daily exercise has the same effect on the blood pressures in all patients.
E. The drug has little or no effects on patients with normal blood pressures.

A. Shoplifters usuall steal only items that they need but cannot afford.
B. Retailers do not take shoplifting losses into account when they initially set their prices.
