补充1： PREP1 Q79
To improve the long-term savings rate of the citizens of Levaska, the country's legislature decided to implement a plan that allows investors to save up to $1,000 per year in special accounts without paying taxes on the interest earned unless withdrawals are made before the investor reaches age sixty-five.  Withdrawals from these accounts prior to age sixty-five would result in the investor's having to pay taxes on all the accumulated interest at the time of withdrawal.

Which of the following, if true, most strongly supports the prediction that the legislature's plan will have its intended effect?

A. The money saved in the tax-free savings accounts will be deposited primarily in those banks and financial institutions that supported the legislation instituting the plan.
B. The majority of people choosing to take advantage of the tax-free savings accounts will withdraw their money prior to age sixty-five.
C. A significant number of the citizens of Levaska will invest in the tax-free savings accounts well before they reach the age of sixty-five.
D. During the ten years prior to implementation of the plan, Levaskans deposited an increasingly smaller percentage of their annual income in long-term savings accounts.
E. People who are not citizens of Levaska are not eligible to invest in the tax-free savings accounts, even if their income is taxable in Levaska.


ANSWER: C
补充2   PREP1 Q80
In Europe, many large animal species, such as mammoths, became extinct soon after humans first migrated to the animals' areas of habitation.  The spread of such extinctions closely followed the pattern of human migration.  However, since humans tended to migrate to areas as the climate in those areas began to warm, the extinctions might have been precipitated by the climatic warming rather than by human migration.

Which of the following, if true, provides the best evidence that it was human migration and not climatic change that precipitated the extinctions?

A. Many animal species, such as deer and bison, continued to thrive in Europe even after humans migrated there.
B. Several periods of marked climatic warming have occurred in Europe, during which many large animal species that lived there became extinct.
C. Many animal species that became extinct in Europe survived longer in areas that were isolated from human populations but that experienced intense climatic warming.
D. In some areas of Europe, only a few archaeological sites have yielded evidence that shows an overlap between the arrival of humans and the extinction of large animals.
E. Some large animals had become extinct in Europe even before humans migrated there.

ANSWER:  C


1. PREP2  Q76
In response to mounting public concern, an airplane manufacturer implemented a program with the well-publicized goal of reducing by half the total yearly amount of hazardous waste generated by its passenger-jet division.  When the program began in 1994, the division's hazardous waste output was 90 pounds per production worker; last year it was 40 pounds per production worker.  Clearly, therefore, charges that the manufacturer's program has not met its goal are false.  

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

A. The amount of nonhazardous waste generated each year by the passenger-jet division has not increased significantly since 1994.
B. At least as many passenger jets were produced by the division last year as had been produced in 1994.
C. Since 1994, other divisions in the company have achieved reductions in hazardous waste output that are at least equal to that achieved in the passenger-jet division.
D. The average number of weekly hours per production worker in the passenger-jet division was not significantly greater last year than it was in 1994.
E. The number of production workers assigned to the passenger-jet division was not significantly less in 1994 than it was last year.


Answer: E

2. PREP2  Q77. (30553-!-item-!-188;#058&005527)
Citizens of Parktown are worried by the increased frequency of serious crimes committed by local teenagers.  In response, the city government has instituted a series of measures designed to keep teenagers at home in the late evening.  Even if the measures succeed in keeping teenagers at home, however, they are unlikely to affect the problem that concerns citizens, since most crimes committed by local teenagers take place between 3 p.m. and 6 p.m.

Which of the following, if true, most substantially weakens the argument?

A. Similar measures adopted in other places have failed to reduce the number of teenagers on the streets in the late evening.
B. The crimes committed by teenagers in the afternoon are mostly small thefts and inconsequential vandalism.
C. Teenagers are much less likely to commit serious crimes when they are at home than when they are not at home.
D. Any decrease in the need for police patrols in the late evening would not mean that there could be more intensive patrolling in the afternoon.

3. PREP2  Q78. (32009-!-item-!-188;#058&006754)

Kitchen magazine plans to license the use of its name by a line of cookware.  For a magazine, licensing the use of its name for products involves some danger, since if the products disappoint consumers, the magazine's reputation suffers, with consequent reductions in circulation and advertising.  However, experts have evaluated the cookware and found it superior to all other cookware advertised in Kitchen.  Therefore, Kitchen can collect its licensing fee without endangering its other revenues.

The argument above assumes which of the following?

A. No other line of cookware is superior to that which will carry the Kitchen name.
B. Kitchen will not license the use of its name for any products other than the line of cookware.
C. Makers of cookware will not find Kitchen a less attractive advertising vehicle because the magazine's name is associated with a competing product.

ANSWER: C

4. PREP2  Q100. (30745-!-item-!-188;#058&005748)
Lyme disease is caused by a bacterium transmitted to humans by deer ticks.  Generally, deer ticks pick up the bacterium while in the larval stage by feeding on infected white-footed mice.  However, certain other species on which the larvae feed do not harbor the bacterium.  If the population of these other species were increased, more of the larvae would be feeding on uninfected hosts, so the number of ticks acquiring the bacterium would likely decline.

Which of the following would it be most important to ascertain in evaluating the argument?

A. Whether populations of the other species on which deer tick larvae feed are found only in areas also inhabited by white-footed mice
B. Whether the size of the deer tick population is currently limited by the availability of animals for the tick's larval stage to feed on
C. Whether the infected deer tick population could be controlled by increasing the number of animals that prey on white-footed mice
D. Whether deer ticks that were not infected as larvae can become infected as adults by feeding on deer on which infected deer ticks have fed
E. Whether the other species on which deer tick larvae feed harbor any other bacteria that ticks transmit to humans


ANSWER: B

1.

Background: Medical researcher: As expected, records covering
the last four years of ten major hospitals
indicate that babies born prematurely were
more likely to have low birth weights and to
suffer from health problems than were babies
not born prematurely.

Premise: These records also
indicate that mothers who had received
adequate prenatal care were less likely to have
low birth weight babies than were mothers who
had received inadequate prenatal care.

Conclusion: Adequate prenatal care, therefore, significantly
decreases the risk of low birth weight babies.

(B) Correct, right to the point

2.

Background: Sales of telephones have increased dramatically over the last year.

Premise: n order to take
advantage of this increase, Mammoth Industries plans to expand production of its own model

Conclusion: while continuing its already very extensive advertising of this product.

(E)

3.

Background: ank depositors in the United States are all financially protected against bank failure because
the government insures all individuals' bank deposits.

Premise: An economist argues that this
insurance is partly responsible for the high rate of bank failures, since it removes from
depositors any financial incentive to find out whether the bank that holds their money is
secure against failure.

Conclusion: if depositors were more selective, then banks would need to be
secure in order to compete for depositors' money.

(E)

4.

Background: A drug that is highly effective in treating many types of infection can, at
present, be obtained
only from the bark of the ibora

Premise: a tree that is quite rare in the wild. It takes the bark of
5,000 trees to make one kilogram of the drug.

Conclusion: It follows, therefore, that continued
production of the drug must inevitably lead to the ibora's extinction.

(D) Correct, the tree doesn't die from harvesting

5.

Background: Manufacturers sometimes discount the price of a product to retailers for a promotion period
when the product is advertised to consumers.


Premise: Such promotions often result in a dramatic
increase in amount of product sold by the manufacturers to retailers.


Conclusion: Nevertheless, the
manufacturers could often make more profit by not holding the promotions.

(D) Correct

B. At least as many passenger jets were produced by the division last year as had been produced in 1994. emmm....感觉没什么关系，取非之后好像不能削弱，待定
C. Since 1994, other divisions in the company have achieved reductions in hazardous waste output that are at least equal to that achieved in the passenger-jet division.
other divisions超出范围，排除
D. The average number of weekly hours per production worker in the passenger-jet division was not significantly greater last year than it was in 1994. 取非无法削弱
