Sunflowers growing in pots were placed, with their roots submerged, in the pond contaminated with radioactive elements.  The sunflowers kept growing; in the process, they absorbed radioactive elements.  Within twelve days, 85 percent of the radioactive elements were removed from the water, which is no less than can be accomplished with the much more expensive conventional filtration techniques.  Scientists therefore propose using sunflowers for decontamination wherever there are radioactively contaminated ponds.

Which of the following, if true, points to a limitation on the applicability of the proposed method of decontamination?

1. Some plants other than sunflowers can also remove radioactive elements from water.
2. The water in many ponds contaminated with radioactive elements is so cold that it would kill sunflowers whose roots were submerged in it.
3. Sunflowers that grow with their roots submerged in water grow less well than sunflowers growing under optimal conditions on dry land.
4. Only species of sunflowers with large leaves can have their roots submerged in water and still keep growing.
5. In ponds in which the circulation of the water is artificially increased, sunflowers absorb radioactive elements far faster than they do in other ponds.

The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia.  Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed.  However, recent statistics show a droip in the number of television assemblers in Borodia.  Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.

Which of the following is an assumption on which the argument depends?

1. The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.
2. Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
3. The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.
4. The number of televisions assembled annually in Vernland has increased significantly during the past three years.
5. The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years.

The city of Workney, in raising bus fares from $1.00 to $1.25, proposed that 18 fare tokens be sold for $20.00 to alleviate the extra burden of the fare increase on the city’s low-income residents.  Critics suggested alternatively that 9 fare tokens be sold for $10.00, because a $20.00 outlay would be prohibitive for low-income riders.

The alternative proposal depends on which of the following assumptions?

1. Low-income residents of Workney will continue to ride the buses in the same numbers despite the fare increase.
2. Low-income riders would be more likely to take advantage of the savings afforded by the 9-token offer than would other riders.
3. The outlay of $10.00 for the purchase of 9 fare tokens would not be prohibitive for low-income bus riders.

Tanco, a leather manufacturer, uses large quantities of common salt to preserve animal hides.  New environmental regulations have significantly increased the cost of disposing of salt water that results from this use, and, in consequence, Tanco is considering a plan to use potassium chloride in place of common salt.  Research has shown that Tanco could reprocess the by-product of potassium chloride use to yield a crop fertilizer, leaving a relatively small volume of waste for disposal.

In determining the impact on company profits of using potassium chloride in place of common salt, it would be important for Tanco to research all of the following EXCEPT:

1. What difference, if any, is there between the cost of the common salt needed to preserve a given quantity of animal hides and the cost of the potassium chloride needed to preserve the same quantity of hides?
2. To what extent is the equipment involved in preserving animal hides using common salt suitable for preserving animal hides using potassium chloride?
3. What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride?
4. How closely does leather that results when common salt is used to preserve hides resemble that which results when potassium chloride is used?

Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development.  They plan to do this by purchasing that land from the farmers who own it.  That plan is ill-conceived:  if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders.  On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable.  But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires.  And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability.

In the argument as a whole, the two boldface proportions play which of the following roles?

1. The first presents a goal that the argument concludes cannot be attained; the second is a reason offered in support of that conclusion.
2. The first presents a goal that the argument concludes can be attained; the second is a judgment disputing that conclusion.
3. The first presents a goal, strategies for achieving which are being evaluated in the argument; the second is a judgment providing a basis for the argument’s advocacy of a particular strategy.

Astronomer:  Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter’s atmosphere in 1994, but they did not show how big those fragments were.  Nevertheless, some indication of their size can be inferred from spectrographic analyses of Jupiter’s outer atmosphere.  After the fragments’ entry, these analyses revealed unprecedented traces of sulfur.  The fragments themselves almost certainly contained no sulfur, but astronomers believe that the cloud layer below Jupiter’s outer atmosphere does contain sulfur.  Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter’s outer atmosphere without being burned up.

In the astronomer’s argument, the two portions in boldface play which of the following roles?

1. The first is a claim that the astronomer seeks to show is true; the second acknowledges a consideration that weighs against the truth of that claim.
2. The first is a claim that the astronomer seeks to show is true; the second provides evidence in support of the truth of that claim.
3. The first and the second are each considerations advanced in support of the conclusion of the argument.
4. The first provides evidence in support of the conclusion of the argument; the second is that conclusion.
5. The first is a circumstance for which the astronomer seeks to provide an explanation; the second acknowledges a consideration that weighs against the explanation provided by the astronomer.

第一段：1908年，在某个例案中，高级法院根据一项关于建立印第安人保留区的treaty,规定联邦政府必须保证保留区内印第安人的水权。之后，又作出了详细的规定，规定在以下三种情况下联邦政府可行使该项权利：1、...2、...3、...

第二段：RG这样一个印第安地区，虽然不符合以上1、2两种情况（情况3没有讨论），但事实上也遵循了winter doctrine. 因为，尽管没有正式的文件，但RG一直都被联邦政府视为保留区....最后，还有一个1963年的法律规定联邦政府设立保留区的方式并不影响到这种保留区遵循winter doctrine，因此，最终确定了RG的水权。

The author cites the fact that the Rio Grande pueblos were never formally withdrawn from public lands primarily in order to do which of the following?          

1. Suggest why it might have been argued that the Winters doctrine ought not to apply to pueblo lands
2. Imply that the United States never really acquired sovereignty over pueblo lands
3. Argue that the pueblo lands ought still to be considered part of federal public lands
4. Support the argument that the water rights of citizens other than American Indians are limited by the Winters doctrine

Suggest that federal courts cannot claim jurisdiction over cases disputing the traditional diversion and use of water by Pueblo Indians

The passage suggests that, if the criteria discussed in lines 16 – 32 were the only criteria for establishing a reservation’s water rights, which of the following would be true?        

1. The water rights of the inhabitants of the Fort Berthold Indian Reservation would not take precedence over those of other citizens.
2. Reservations established before 1848 would be judged to have no water rights.
3. There would be no legal basis for the water rights of the Rio Grande pueblos.

According to the passage, which of the following was true of the treaty establishing the Fort Berthold Indian Reservation?

1. It was challenged in the Supreme Court a number of times.
2. It was rescinded by the federal government, an action that gave rise to the Winters case.
3. It cited American Indians’ traditional use of the land’s resources.
4. It failed to mention water rights to be enjoyed by the reservation’s inhabitants.
5. It was modified by the Supreme Court in Arizona v. California.

2. explain the legal bases for the water rights of American Indian tribes
3. question the legal criteria often used to determine the water rights of American Indian tribes
4. discuss evidence establishing the earliest date at which the federal government recognized the water rights of American Indians
5. point out a legal distinction between different types of American Indian reservations

主旨题
本题分析：
根据全文翻译可知文章的主旨就是在讨论印第安人保留地用水权的法律依据。

Rye sown in the fall and plowed into the soil in early spring leaves a residue that is highly effective at controlling broad-leaved weeds, but unfortunately for only about 45 days.  No major agricultural crop matures from seed in as little as 45 days.  Synthetic herbicides, on the other hand, although not any longer-lasting, can be reapplied as the crop grows.  Clearly, therefore, for major agricultural crops, plowing rye into the soil can play no part in effective weed control.

The argument is most vulnerable to the objection that it fails to

1. consider that there might be minor, quick-growing crops that do mature in 45 days or less
2. identify any alternative method of weed control that could be used instead of the method it rejects
3. distinguish among the various kinds of synthetic herbicides
4. allow for the possibility of combining the two weed-control methods it mentions
5. allow for the possibility that plants other than rye, handled the same way, might have the same effect

Fearing competition from stores that rent video games for home use, owners of stores that sell video games lobbied for protective

legislation.  Citing as a precedent legislation that postpones home film rentals until one year after general release to theaters, the video sellers proposed as an equitable solution a plan that would postpone rental of any video game until it had been available for sale for one year.

Which of the following, if true, would support an objection by owners of video rental stores that the fairness of the proposed legislation is not supported by the precedent cited?

1. Although the daily rental fee for home use of films is generally the same as that for video games, the average rental period for a video game is longer than that for a film.
2. Film rentals for home use tend to particularly strong during the first year after a film has been made available for both sale and rental at video rental stores.
3. Most people are interested in playing only the latest video games and tend to find video games that have been available for over a year unappealing whether they have played them before or not, whereas films maintain their appeal far longer after their release.
4. People who rent video games tend to play them by themselves, whereas people who rent films invite friends and neighbors to watch.
5. A slight decline in revenues from films that have been recently released in theaters has been attributed to the growing market for rentals of films for home use.

Press Secretary:  Our critics claim that the President’s recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties.  They offer as evidence the fact that 90 percent of the projects canceled were in such districts.  But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors.  So the President’s choice was clearly motivated by sound budgetary policy, not partisan politics.

Which of the following is an assumption on which the press secretary’s argument depends?

1. Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.
2. The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party.
3. The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future.
4. The highway projects canceled in districts controlled by the President’s party were not generally more expensive than the projects canceled in districts controlled by opposition parties.
5. Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.

1.      GWD-10-Q33 -Q35旅行社业另辟蹊径走向全球化 

(This passage was excerpted from material

published in 1993.)

Like many other industries, the

travel industry is under increasing

pressure to expand globally in order

Line to keep pace with its corporate cus-

(5) tomers, who have globalized their

operations in response to market

pressure, competitor actions, and

changing supplier relations. But it is

difficult for service organizations to

(10) globalize. Global expansion through

acquisition is usually expensive, and

expansion through internal growth is

time-consuming and sometimes

impossible in markets that are not

(15) actively growing. Some service industry

companies, in fact, regard these

traditional routes to global expansion

as inappropriate for service industries

because of their special need to pre-

(20) serve local responsiveness through

local presence and expertise. One

travel agency has eschewed the traditional

route altogether. A survivor

of the changes that swept the travel

(25) industry as a result of the deregulation

of the airlines in 1978—changes that

included dramatic growth in the corporate

demand for travel services,

as well as extensive restructuring and

(30) consolidation within the travel industry—

this agency adopted a unique structure

for globalization. Rather than expand

by attempting to develop its own offices

abroad, which would require the devel-

(35) opment of local travel management

expertise sufficient to capture foreign

markets, the company solved its

globalization dilemma effectively by

forging alliances with the best foreign

(40) partners it could find. The resulting

cooperative alliance of independent

agencies now comprises 32 partners

spanning 37 countries.

结论解释

Like many other industries, the travel industry… But it is difficult for service organization to globalize, expensive, time-consuming, impossible. One has eschewed.. a survivor… solved dilemma effectively….

The passage suggests that one of the effects of the deregulation of the airlines was          

1. a decline in the services available to noncommercial travelers
2. a decrease in the size of the corporate travel market
3. a sharp increase in the number of cooperative alliances among travel agencies
4. increased competition in a number of different service industries

Unless tiger hunting decreases, tigers will soon be extinct in the wild.  The countries in which the tigers’ habitats are located are currently debating joint legislation that would ban tiger hunting.  Thus, if these countries can successfully enforce this legislation, the survival of tigers in the wild will be ensured.

The reasoning in the argument is most vulnerable to criticism on the grounds that the argument

1. assumes without sufficient warrant that a ban on tiger hunting could be successfully enforced
2. considers the effects of hunting on tigers without also considering the effects of hunting on other endangered animal species
3. fails to take into account how often tiger hunters are unsuccessful in their attempts to kill tigers
