Hevelia airstrip, 40 miles away, would, if upgraded and expanded, be an attractive alternative for fully 20 percent of the passengers using Greentown airport. Nevertheless, experts reject the claim that turning Hevelia into a full-service airport would end the chronic delays at Greentown.Which of the following, if true, most helps to justify experts' position?A Turning Hevelia into a full-service airport would require not only substantial construction at the airport itself, but also the construction of new access highways.B A second largely undeveloped airstrip close to Greentown airport would be a more attractive alternative than Hevelia for many passengers who now use Greentown.C Hevelia airstrip lies in a relatively undeveloped area but would, if it became a full-service airport, be a magnet for commercial and residential development.D If an airplane has to wait to land, the extra jet fuel required adds significantly to the airline's costs.E Several airlines use Greentown as a regional hub, so that most flights landing at Greentown have many passengers who then take different flights to reach their final destinations.正确答案：E题目翻译：G机场需要减少10%的客流才能避免目前的拥挤。

TEST ATime 30 minutes 20 Questions1. Mr. Janeck: I don’t believe Stevenson will win the election for governor. Fewvoters are willing to elect a businessman with no political experience to such a responsible public office.Ms. Siuzdak: You’re wrong. The experience of running a major corporation is a valuable preparation for the task of running a state government.M. Siuzdak’s response shows that she has interpreted Mr. Janeck’s remark toimply which of the following?(A) Mr. Janeck considers Stevenson unqualified for the office of governor.(B) No candidate without political experience has ever been elected governor of astate.(C) Mr. Janeck believes that political leadership and business leadership areclosely analogous.(D) A career spent in the pursuit of profit can be an impediment to one’s ability torun a state government fairly.(E) V oters generally overestimate the value of political experience when selectinga candidate.2. Which of the following best completes the passage below?One tax-reform proposal that has gained increasing support in recent years is the flat tax, which would impose a uniform tax rate on incomes at every level.Opponents of the flat tax say that a progressive tax（累进税）system, which levies a higher rate of taxes on higher-income taxpayers, is fairer, placing thegreater burden on those better able to bear it. However, the present crazy quilt of tax deductions（扣除）, exemptions（免税额）, credits, and loopholes benefits primarily the high-income taxpayer, who is consequently able to reduce his or her effective tax rate, often to a level below that paid by the lower-income taxpayer.Therefore, ______(A) higher-income taxpayers are likely to lend their support to the flat-taxproposal now being considered by Congress(B) a flat-tax system that allowed no deductions or exemptions wouldsubstantially increase actual government revenues(C) the lower-income taxpayer might well be penalized by the institution of aflat-tax system in this country(D) the progressive nature of our present tax system is more illusory（虚幻的）than real(E) the flat tax would actually be fairer to the lower-income taxpayer than anyprogressive tax system could be3. As part of our program to halt（停止）the influx（涌入）of illegal immigrants（移民）, the administration is proposing the creation of a national identity card.The card would be available only to U.S. citizens and to registered（注册登记）aliens, and all persons would be required to produce the card before they could be given a job. Of course, such a system holds the potential, however slight, for the abuse of civil liberties. Therefore, all personal information gathered through this system would be held strictly confidential, to be released only by authorizedpersonnel under appropriate circumstances. Those who are in compliance（服从、听从）with U.S. laws would have nothing to fear from the identity card system.In evaluating the above proposal, a person concerned about the misuse ofconfidential information would be most interested in having the author clarify（使澄清）the meaning of which of the following phrases?(A) “all persons” (line 5)(B) “however slight” (line 7)(C) “civil liberties” (line 8)(D) “appropriate circumstances（适当的条件下）” (line 11)(E) “U.S. laws” (line 2)4. At one time, European and Japanese companies tried to imitate（模仿）theirAmerican rivals（竞争对手）. Today, American appliance manufacturers（制造商）import European scientists to lead their research staffs; Americanautomakers design cars that mimic the styling of German, Italian, and Frenchimports; and American electronics firms boast（自吹自擂）in their advertising of “Japanese-style” devotion to quality and reliability. In the world of hightechnology, America has lost the battle for international prestige（国际威望）.Each of the following statements, if true, would help to support the claim above EXCEPT:(A) An American camera company claims in its promotional literature to producecameras “as fine as the best Swiss imports.”(B) An American maker of stereo components designs its products to resemblethose of a popular Japanese firm.(C) An American manufacturer of video games uses a brand name chosenbecause it sounds like a Japanese word.(D) An American maker of televisions studies German-made televisions in orderto adopt German manufacturing techniques.(E) An American maker of frozen foods advertises its dinners as “RealEuropean-style entrees prepared by fine French and Italian chefs.”5. Johnson is on firm ground（坚定的）when he asserts（声称、断言）that the earlyeditors of Dickinson’s poetry often distorted（扭曲）her intentions. Yet Johnson’s own, more faithful, text is still guilty of its own forms of distortion. Tostandardize（使规范）Dickinson’s often indecipherable handwritten punctuation by the use of the dash is to render permanent a casual mode of poetic phrasingthat Dickinson surely never expected to see in print. It implies that Dickinsonchose the dash as her typical mark of punctuation when, in fact, she apparently never made any definitive choice at all.Which of the following best summarizes the author’s main point?(A) Although Johnson is right in criticizing Dickinson’s early editors for theirdistortion of her work, his own text is guilty of equally serious distortions.(B) Johnson’s use of the dash in his text of Dickinson’s poetry misleads readersabout the poet’s intentions.(C) Because Dickinson never expected her poetry to be published, virtually anyattempt at editing it must run counter to her intentions.(D) Although Johnson’s attempt to produce a more faithful text of Dickinson’spoetry is well-meaning, his study of the material lacks sufficientthoroughness.(E) Dickinson’s editors, including Johnson, have failed to deal adequately withthe problem of deciphering Dickinson’s handwritten manuscripts.6. A law requiring companies to offer employees unpaid time off to care for theirchildren will harm the economic competitiveness of our nation’s businesses.Companies must be free to set their own employment policies without mandated parental-leave regulations.Which of the following, if true, would most seriously weaken the conclusion of the argument above?(A) A parental-leave law will serve to strengthen the family as a social institutionin this country.(B) Many businesses in this country already offer employees some form ofparental leave.(C) Some of the countries with the most economically competitive businesseshave strong parental-leave regulations.(D) Only companies with one hundred or more employees would be subject to theproposed parental-leave law.(E) In most polls, a majority of citizens say they favor passage of a parental-leavelaw.7. If A, then B.If B, then C.If C, then D.If all of the statements above are true, which of the following must also be true?(A) If D, then A.(B) If not B, then not C.(C) If not D, then not A.(D) If D, then E.(E) If not A, then not D.8. Dear Applicant:Thank you for your application. Unfortunately, we are unable to offer you aposition in our local government office for the summer. As you know, funding for summer jobs is limited, and it is impossible for us to offer jobs to all those who want them. Consequently, we are forced to reject many highly qualifiedapplicants.Which of the following can be inferred from the letter?(A) The number of applicants for summer jobs in the government office exceededthe number of summer jobs available.(B) The applicant who received the letter was considered highly qualified.(C) Very little funding was available for summer jobs in the government office.(D) The application of the person who received the letter was consideredcarefully before being rejected.(E) Most of those who applied for summer jobs were considered qualified for theavailable positions.9. Studies of fatal automobile accidents reveal（揭示、显露）that, in the majorityof cases in which one occupant of an automobile is killed while another survives, it is the passenger, not the driver, who is killed. It is ironic that the innocentpassenger should suffer for the driver’s carelessness, while the driver oftensuffers only minor injuries or none at all.Which of the following is an assumption（假设）underlying（潜在的）the reasoning in the passage above?(A) In most fatal（致命的、严重的）automobile accidents, the driver of a car inwhich an occupant is killed is at fault.(B) Drivers of automobiles are rarely killed in auto accidents.(C) Most deaths in fatal automobile accidents are suffered by occupants of carsrather than by pedestrians.(D) Auto safety experts should increase their efforts to provide protection forthose in the passenger seats of automobiles.(E) Automobile passengers sometimes play a contributing role in causing autoaccidents.Questions 10-11 are based on the followingAs one who has always believed that truth is our nation’s surest weapon in the propaganda war against our foes, I am distressed by reports of “disinformation”campaigns by American intelligence agents in Western Europe. In a disinformation campaign, untruths are disseminated（散步、传播）through gullible（易受骗的）local journalists in order to damage the interests of our enemies and protect our own. Those who defend this practice say that lying is necessary to counter Soviet disinformation campaigns aimed at damaging America’s political interests. These apologists contend that one must fight fire with fire. I would point out to the apologists that the firedepartment finds water more effective.10. The author of the passage above bases his conclusion on which of the following?(A) A circular（迂回的、圆形的）definition of “disinformation”(B) An example of the ineffectiveness of lying as a weapon in the propagandawar(C) An analogy（类似、比拟、类推）between truth and water(D) An appeal to the authority of the fire department(E) An attack on the character of American intelligence agents in Western Europe11. The author’s main point is that(A) although disinformation campaigns may be effective, they are unacceptableon ethical grounds(B) America’s moral standing in the world depends on its adherence to the truth(C) the temporary political gains produced by disinformation campaignsgenerally give way to long-term losses(D) Soviet disinformation campaigns have done little to damage America’sstanding in Europe(E) disinformation campaigns do not effectively serve the political interests of theUnited States12.

Read the Daily Clarion, the only real voice of thepeople of Gotham City!Which of the following most directly refutes the argument raised in theadvertisement above?(A) Over half of the advertising revenues of the Daily Clarion come from firmswhose headquarters are located outside of Gotham City.(B) The Daily Clarion usually devotes more of its pages to out-of-town news thandoes the Daily Bugle.(C) Nearly 40 percent of the readers of the Daily Clarion reside outside the limitsof Gotham City.(D) The editor-in-chief and all the other members of the editorial staff of theDaily Bugle have lived and worked in Gotham City for ten years or more.(E) The Daily Bugle has been published in Gotham City for a longer time thanhas the Daily Clarion.Questions 13-14 are based on the following.The earth’s resources are being depleted much too fast. To correct this, the United States must keep its resource consumption at present levels for many years to come.13. The argument above depends on which of the following assumptions?(A) Per capita resource consumption in the United States is at an all-time high.(B) The United States wastes resources.(C) The United States uses more resources than any other country.(D) The United States imports most of the resources it uses.(E) Curbing U.S. resource consumption will significantly retard world resourcedepletion.14. Which of the following, if true, would most strengthen the argument above?(A) New resource deposits are constantly being discovered.(B) The United States consumes one-third of all resources used in the world.(C) Other countries need economic development more than the United Statesdoes.(D) Other countries have agreed to hold their resource consumption at presentlevels.(E) The United States has been conserving resources for several years.15. Alba: I don’t intend to vote for Senator Frank in the next election. She is not astrong supporter of the war against crime.Tam: But Senator Frank sponsored the latest anticrime law passed by the Senate.Alba: If Senator Frank sponsored it, it can’t be a very strong anticrime law.Which of the following identifies the most serious logical flaw in Alba’sreasoning?(A) The facts she presents do not support her conclusion that Senator Frank issoft on crime.(B) She assumes without proof that crime is the most important issue in theupcoming election.(C) She argues in a circle, using an unsupported assertion to dismiss conflictingevidence.(D) She attacks Senator Frank on personal grounds rather than on he merit as apolitical leader.(E) In deciding not to vote for Senator Frank, she fails to consider issues otherthan crime.16. Which of the following best completes the passage below?the most serious flaw in television’s coverage of election campaigns is itstendency to focus on the horse-race side of politics—that is, to concentrate on the question “Who’s winning?” at the expense of substantive coverage of the issues and the candidates’ positions on them. The endless interviews with campaignmanagers, discussions of campaign strategies, and, especially, the obsession with opinion polls have surrounded elections with the atmosphere of a football game or a prizefight. To reform this situation, a first step might well be______(A) a shortening of the length of election campaigns to a period of six weeks(B) a stringent limit on campaign spending(C) a reduction in the television coverage of opinion polls during electioncampaigns(D) the publication and distribution of voter-education literature to inform thepublic about each candidate’s position on the major issues(E) a limit on the length and number of political advertisements broadcast ontelevision17. With Proposition 13, if you bought your house 11 years ago for $75,000, yourproperty tax would be approximately $914 a year (1 percent of $75,000 increased by 2 percent each year for 11 years); and if your neighbor bought an identicalhouse next door to you for $200,000 this year, his tax would be $2,000 (1 percent of $200,000). Without Proposition 13, both you and your neighbor would pay$6,000 a year in property taxes (3 percent of $200,000).Which of the following is the conclusion for which the author most likely isarguing in the passage above?(A) Proposition 13 is unconstitutional because it imposes an unequal tax onproperties of equal value.(B) If Proposition 13 is repealed, every homeowner is likely to experience asubstantial increase in property taxes.(C) By preventing inflation from driving up property values, Proposition 13 hassaved homeowners thousands of dollars in property taxes.(D) If Proposition 13 is not repealed, identical properties will continue to be taxedat different rates.(E) Proposition 13 has benefited some homeowners more than others. Questions 18-19 are based on the following.At an enormous research cost, a leading chemical company has developed a manufacturing process for converting wood fibers into a plastic. According to the company, this new plastic can be used for, among other things, the hulls of small sailboats. But what does the company think sailboat hulls used to be made of? Surely the mania for high technology can scarcely go further than this.18. The author’s opinion of the manufacturing process described in the passage isbased primarily on the fact that(A) plastic is unlikely to be durable enough for high-quality sailboat hulls(B) the research costs of developing the process outweigh any savings possiblefrom the use of the plastic(C) a small sailboat is not normally regarded as a high-tech product(D) hulls for small sailboats can be made from wood without converting it intoplastic(E) many other spheres of human activity are in far greater need of technologicalresearch19. Which of the following, if true, would most seriously weaken the author’sconclusion?(A) The plastic produced by the process is considerably lighter, stronger, andmore watertight than wood.(B) The wood used in producing the plastic is itself in increasingly short supply.(C) The cost of the manufacturing process of the plastic increases the cost ofproducing a sailboat hull by 10 to 15 percent.(D) Much of the cost of the research that developed the new process will bewritten off for tax purposes by the chemical company.(E) The development of the new plastic is expected to help make the chemicalcompany an important supplier of boat-building materials.20. A young man eager to become a master swordsman journeyed to the home of thegreatest teacher of swordsmanship in the kingdom. He asked the teacher, “How quickly can you teach me to be a master swordsman?” The old teacher replied, “It will take ten years.” Unsatisfied, the young man asked, “What if I am willing to work night and day, every day of the year?” the teacher replied, “In that case, it will take twenty years.”The teacher’s main point is that an important quality of a master swordsman is(A) humility(B) willingness to work hard(C) respect for one’s elders(D) patience(E) determinationTEST BTime 30 minutes 20 Questions1. Below is an excerpt from a letter that was sent by the chairman of a corporationto the stockholders.A number of charges have been raised against me, some serious, some trivial.Individuals seeking to control the corporation for their own purposes havedemanded my resignation. Remember that no court of law in any state has found me guilty of any criminal offense whatsoever. In the American tradition, as you know, an individual is considered innocent until proven guilty. Furthermore, as the corporation’s unbroken six-year record of growth will show, my conduct of my official duties as chairman has only helped enhance the success of thecorporation, and so benefited every stockholder.Which of the following can be properly inferred from the excerpt?(A) The chairman believes that all those who have demanded his resignation aremotivated by desire to control the corporation for their own purposes.(B) Any misdeeds that the chairman may have committed were motivated by hisdesire to enhance the success of the corporation.(C) The chairman is innocent of any criminal offense.(D) The corporation has expanded steadily over the past six years.(E) Any legal proceedings against the chairman have resulted in his acquittal.2.

Which of the following best completes the passage below?In opposing government regulation of business, conservatives often appeal to the Jeffersonian ideal of limited government, expressing the wish that government would “get off the backs of the American people.” Yet, paradoxically, many of these same conservatives address questions of private morality, such as thosedealing with sexual behavior, by calling for______(A) a return to the restrictive sexual morality of the Victorian era(B) a strengthening of the role of the family in setting moral norms for society(C) a limitation on the amount of sexually provocative material appearing inbooks, motives, and television shows(D) greater freedom for individuals to choose their own way of handling sexualissues(E) an increased governmental role in the regulation and control of private sexualbehaviorQuestions 4-5 are based on the following:In an experiment, two different types of recorded music were played for neonates in adjacent nurseries in a hospital. In nursery A, classical music was played; in nursery B, rock music was played. After two weeks, it was found that the babies in nursery A cried less, suffered fewer minor ailments, and gained more weight than did the babies in nursery B.4. In evaluating the validity of the conclusion suggested by the experiment above, itwould be most important to know which of the following?(A) The musical preferences of the parents of the two groups of newborns(B) Whether the newborns in both nurseries were equally healthy and happy atthe start of the experiment(C) Whether loud rock music can damage the hearing of newborns(D) What the average weight of the neonates was before and after the experiment(E) Whether the music was played in the nurseries at all times or only at certaintimes5.

The ancient city of Cephesa was not buried by an eruption of Mt. Amnos in A.D.310, as some believe. The eruption in the year 310 damaged the city, but it did not destroy it. Cephesa survived for another century before it finally met itsdestruction in another eruption around A.D. 415.Which of the following, if true, would most strengthen the author’s claim that the city of Cephesa was not buried by the eruption of Mt. Amnos in A.D. 310?(A) The city of Cephesa is mentioned in a historical work known to have beenwritten in A.D. 400.(B) Coins bearing the image of an emperor who lived around A.D. 410 have beendiscovered in the ruins of Cephesa, which were preserved by the cinders andashes that buried the city.(C) Geological evidence shows that the eruption of Mt.

Reva: Using extraneous incentives to get teenagers to change their attitudetoward school and schoolwork won’t work. Take the program in West Virginia,for instance, where they tried to reduce their dropout rate by revoking the driving licenses of kids who left school. The program failed miserably.Anne: It’s true that the West Virginia program failed, but many schools havedevised incentive programs that have been very successful in improvingattendance and reducing discipline problems.According to Anne, the weak point in Reva’s claim is that it(A) fails to consider the possibility that the majority of potential dropouts in WestVirginia do not have driving licenses(B) doesn’t provide any exact figures for the dropout rate in West Virginia beforeand during the program(C) ignores a substantial body of evidence showing that parents and employershave been using extrinsic incentives with positive results for years(D) assumes that a positive incentive—a prize or a reward—will be no moreeffective than a negative incentive, like the revoking of a driving license(E) is based on a single example, the incentive program in West Virginia, whichmay not be typical10. In many surveys, American consumers have expressed a willingness to spend upto 10 percent more for products that are ecologically sound. Encouraged by such surveys, Bleach-O Corporation promoted a new laundry detergent, Bleach-OGreen, as safer for the environment. Bleach-O Green cost 5 percent more thantypical detergents.

Gmat考试逻辑试题90题(1)1. Although 90 percent of the population believes itself to be well inFORMed about health care, only 20 percent knows enough about DNA. So apparently at least 80 percent of the population does not know enough about medical concepts to make well-inFORMed personal medical choices or to make good public policy decisions about health care.The argument's reasoning is questionable because the argument fails to demonstrate that(A) those people who can understand news stories about DNA are able to make well-inFORMed personal medical choices(B) more than 20 percent of the population needs to be well inFORMed about health care for good public policy decisions about health care to be made(C) one's being able to make well-inFORMed personal medical choices ensures that one makes good public policy decisions about health care(D) an understanding of DNA is essential to making well-inFORMed personal medical choices or to making goodpublic policy decisions about health care(E) since 90 percent of the population believes itself to be well inFORMed about health care, at least 70 percent of the population is mistaken in that belief.2. During the 1980's, Japanese collectors were very active in the market for European art, especially as purchasers of nineteenth-century Impressionist paintings. This striking pattern surely reflects a specific preference on the part of many Japanese collectors for certain aesthetic attributes they found in nineteenth-century Impressionist paintings.Which one of the following, if true, most strongly supports the explanation above?(A) Impressionist paintings first became popular among art collectors in Europe at the beginning of the twentieth century.(B) During the 1980's, the Japanese economy underwent a sustained expansion that was unprecedented in the country's recent history.(C) Several nineteenth-century Impressionist painters adopted certain techniques and visual effects found in Japanese prints that are highly estee11. The average cable television company offers itscustomers 50 channels, but new fiber-optic lines will enable telephone companies to provide 100 to 150 television channels to their customers for the same price as cable companies charge for 50. Therefore, cable companies will be displaced by the new companies within a few years.Which of the following, if true, most helps to strengthen the argument?(A) The initial cost per household of installing new fiber-optic television service will exceed the current cost of installing cable television service.(B) The most popular movies and programs on channels carried by cable companies will also be offered on channels carried by the fiber-optic lines owned by the telephone companies.(C) Cable television companies will respond to competition from the telephone companies by increasing the number of channels they offer.(D) Some telephone companies own cable companies in areas other than those in which they provide telephone services.(E) The new fiber-optic services offered by telephone companies will be subject to more stringent governmentalprogramming regulations than those to which cable companies are now subject.12. The only physical factor preventing a human journey to Mars has been weight. Carrying enough fuel to propel a conventional spacecraft to Mars and back would make even the lightest craft too heavy to be launched from Earth. A device has recently been invented, however, that allows an otherwise conventional spacecraft to refill the craft's fuel tanks with fuel manufactured from the Martian atmosphere for the return trip. Therefore, it is possible for people to go to Mars in a spacecraft that carries this device and then return.Which one of the following is an assumption on which the argument depends?(A) The amount of fuel needed for a spacecraft to return from Mars is the same as the amount of fuel needed to travel from Earth to Mars.(B) The fuel manufactured from the Martian atmosphere would not differ in composition from the fuel used to travel to Mars.(C) The device for manufacturing fuel from the Martian atmosphere would not take up any of the spaceship crew's living space.(D) A conventional spacecraft equipped with the device would not be appreciably more expensive to construct than current spacecraft typically are.(E) The device for manufacturing fuel for the return to Earth weighs less than the tanks of fuel that a conventional spacecraft would otherwise need to carry from Earth for the return trip.13. In 1712 the government of Country Y appointed a censor to prohibit the publication of any book critical of Country Y's government; all new books legally published in the country after 1712 were approved by a censor. Under the first censor, one half of the book manus submitted to the censor were not approved for publication. Under the next censor, only one quarter of the book manus submitted were not approved, but the number of book manus that were approved was the same under both censors. If the statements in the passage are true, which one of the following can be properly concluded from them?(A) More books critical of Country Y's governments were published before the appointment of the first censor than after it.(B) The first censor and the second censor prohibitedthe publication of the same number of book manus.(C) More book manus were submitted for approval to the first censor than to the second.(D) The second censor allowed some book manus to the published that the first censor would have considered critical of Country Y's government.(E) The number of writers who wrote unpublished manus was greater under the first censor than under the second.14. If the government increases its funding for civilian scientific research, private patrons and industries will believe that such research has become primarily the government's responsibility. When they believe that research is no longer primarily their responsibility, private patrons and industries will decrease their contributions toward research. Therefore, in order to keep from depressing the overall level of funding for civilian scientific research, the government should not increase its own funding.Which one of the following is an assumption on which the argument relies?(A) Governments should bear the majority of the financial burden of funding for civilian scientific research.(B) Any increase in government funding would displace more private funding for civilian scientific research than it would provide.(C) Private donations toward research are no longer welcomed by researchers whose work receives government funding.(D) Civilian scientific research cannot be conducted efficiently with more than one source of funding.(E) funding for civilian scientific research is currently at the highest possible level.15. Dental researcher: Filling a cavity in a tooth is not a harmless procedure: it inevitably damages some of the healthy parts of the tooth. Cavities are harmful only if the decay reaches the nerves inside the tooth, and many cavities, if left untreated, never progress to that point. Therefore, dentists should not fill a cavity unless the nerves inside the tooth are in imminent danger from that cavity.Which one of the following principles, if valid, most strongly supports the researcher's reasoning?(A) Dentists should perFORM any procedure that is likely to be beneficial in the long term, but only if the procedure does not cause immediate damage.(B) Dentists should help their patients to prevent cavities rather than waiting until cavities are present to begin treatment.(C) A condition that is only potentially harmful should not be treated using a method that is definitely harmful.(D) A condition that is typically progressive should not be treated using methods that provide only temporary relief.(E) A condition that is potentially harmful should not be left untreated unless it can be kept under constant surveillance.【。

The local board of education found that, because the current physics curriculum has little direct relevance to today’s world, physics classes attracted few high school students. So to attract students to physics classes, the board proposed a curriculum that emphasizes principles of physics involved in producing and analyzing visual images.Which of the following, if true, provides the strongest reason to expect that the proposed curriculum will be successful in attracting students?(A) Several of the fundamental principles of physics are involved in producing and analyzing visual images.(B) Knowledge of physics is becoming increasingly important in understanding the technology used in today’s world.(C) Equipment that a large producer of photographic equipment has donated to the high school could be used in the proposed curriculum.(D) The number of students interested in physics today is much lower than the number of students interested in physics 50 years ago.(E)(E) In today’s world the production and analysis of visual images is of major importance in communications, business, and recreation.2. Many companies now have employee assistance programsthat enable employees, free of charge, to improve their physical fitness, reduce stress, and learn ways to stop smoking. These programs increase worker productivity, reduce absenteeism, and lessen insurance costs for employee health care. Therefore, these programs benefit the company as well as the employee.Which of the following, if true, most significantly strengthens the conclusion above?(A) Physical fitness programs are often the most popular services offered to employees.(B) Studies have shown that training in stress management is not effective for many people.(C) Regular exercise reduces people’s risk of heart disease and provides them with increased energy.(D) Physical injuries sometimes result from entering a strenuous physical fitness program too quickly.(C)(E) Employee assistance programs require companies to hire people to supervise the various programs offered.3. Unlike the wholesale price of raw wool, the wholesale price of raw cotton has fallen considerably in the last year. Thus, although the retail price of cotton clothing at retail clothing stores has not yet fallen, it will inevitably fall.Which of the following, if true, most seriously weakens the argument above?(A) The cost of processing raw cotton for cloth has increased during the last year.(B) The wholesale price of raw wool is typically higher than that of the same volume of raw cotton.(C) The operating costs of the average retail clothing store have remained constant during the last year.(D) Changes in retail prices always lag behind changes inwholesale prices.(A)(E) The cost of harvesting raw cotton has increased in the last year.4. Small-business groups are lobbying to defeat proposed federal legislation that would substantially raise the federal minimum wage. This opposition is surprising since the legislation they oppose would, for the first time, exempt all small businesses from paying any minimum wage.Which of the following, if true, would best explain the opposition of small-business groups to the proposed legislation?(A) Under the current federal minimum-wage law, most small businesses are required to pay no less than the minimum wage to their employees.(B) In order to attract workers, small companies must match the wages offered by their larger competitors, and these competitors would not be exempt under the proposed laws.(C) The exact number of companies that are currently required to pay no less than the minimum wage but that would be exempt under the proposed laws is unknown.(D) Some states have set their own minimum wages—in some cases, quite a bit above the level of the minimum wage mandated by current federal law—for certain key industries.(B)(E) Service companies make up the majority of small businesses and they generally employ more employees per dollar of revenues than do retail or manufacturing businesses.5. Reviewer: The book Art’s Decline argues that European painters today lack skills that were common among European painters of preceding centuries. In this the book must be right, since its analysis of 100 paintings, 50 old and 50 contemporary, demonstrates convincingly that none of the contemporarypaintings are executed as skillfully as the older paintings.Which of the following points to the most serious logical flaw in the reviewer’s argument?(A) The paintings chosen by the book’s author for analysis could be those that most support the book’s thesis.(B) There could be criteria other than the technical skill of the artist by which to evaluate a painting.(C) The title of the book could cause readers to accept the book’s thesis even before they read the analysis of the paintings that supports it.(D) The particular methods currently used by European painters could require less artistic skill than do methods used by painters in other parts of the world.(A)(E) A reader who was not familiar with the language of art criticism might not be convinced by the book’s analysis of the 100 paintings.6. The pharmaceutical industry argues that because new drugs will not be developed unless heavy development costs can be recouped in later sales, the current 20 years of protection provided by patents should be extended in the case of newly developed drugs. However, in other industries new-product development continues despite high development costs, a fact that indicates that the extension is unnecessary.Which of the following, if true, most strongly supports the pharmaceutical indus try’s argument against the challenge made above?(A) No industries other than the pharmaceutical industry have asked for an extension of the 20-year limit on patent protection.(B) Clinical trials of new drugs, which occur after the patentis granted and before the new drug can be marketed, often now take as long as 10 years to complete.(C) There are several industries in which the ratio of research and development costs to revenues is higher than it is in the pharmaceutical industry.(D) An existing patent for a drug does not legally prevent pharmaceutical companies from bringing to market alternative drugs, provided they are sufficiently dissimilar to the patented drug.(B)(E) Much recent industrial innovation has occurred in products—for example, in the computer and electronics industries—for which patent protection is often very ineffective.Questions 7-8 are based on the following.Bank depositors in the United States are all financially protected against bank failure because the government insures all individuals’ bank deposits. 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. If depositors were more selective, then banks would need to be secure in order to compete for depositors’ money.7. The economist’s argument makes which of the following assumptions?(A) Bank failures are caused when big borrowers default on loan repayments.(B) A significant proportion of depositors maintain accounts at several different banks.(C) The more a depositor has to deposit, the more careful he or she tends to be in selecting a bank.(D) The difference in the interest rates paid to depositors bydifferent banks is not a significant factor in bank failures.(E)(E) Potential depositors are able to determine which banks are secure against failure.8. Which of the following, if true, most seriously weakens the economist’s argument?(A) Before the government started to insure depositors against bank failure, there was a lower rate of bank failure than there is now.(B) When the government did not insure deposits, frequent bank failures occurred as a result of depositors’ fears of losing money in bank failures.(C) Surveys show that a significant proportion of depositors are aware that their deposits are insured by the government.(D) There is an upper limit on the amount of an individual’s deposit that the government will insure, but very few indiv iduals’ deposits exceed this limit.(B)(E) The security of a bank against failure depends on the percentage of its assets that are loaned out and also on how much risk its loans involve.9. Passengers must exit airplanes swiftly after accidents, since gases released following accidents are toxic to humans and often explode soon after being released. In order to prevent passenger deaths from gas inhalation, safety officials recommend that passengers be provided with smoke hoods that prevent inhalation of the gases.Which of the following, if true, constitutes the strongest reason not to require implementation of the safety officials’ recommendation?(A) Test evacuations showed that putting on the smoke hoods added considerably to the overall time it took passengersto leave the cabin.(B) Some airlines are unwilling to buy the smoke hoods because they consider them to be prohibitively expensive.(C) Although the smoke hoods protect passengers from the toxic gases, they can do nothing to prevent the gases from igniting.(D) Some experienced flyers fail to pay attention to the safety instructions given on every commercial flight before takeoff.(A)(E) In many airplane accidents, passengers who were able to reach emergency exits were overcome by toxic gases before they could exit the airplane.10. In 1960, 10 percent of every dollar paid in automobile insurance premiums went to pay costs arising from injuries incurred in car accidents. In 1990, 50 percent of every dollar paid in automobile insurance premiums went toward such costs, despite the fact that cars were much safer in 1990 than in 1960.Which of the following, if true, best explains the discrepancy outlined above?(A) There were fewer accidents in 1990 than in 1960.(B) On average, people drove more slowly in 1990 than in 1960.(C) Cars grew increasingly more expensive to repair over the period in question.(D) The price of insurance increased more rapidly than the rate of inflation between 1960 and 1990.(E)(E) Health-care costs rose sharply between 1960 and 1990.11. Caterpillars of all species produce an identical hormone called “juvenile hormone” that maintains feeding behavior. Only when a caterpillar has grown to the right size for pupation to take place does a special enzyme halt the production ofjuvenile hormone. This enzyme can be synthesized and will, on being ingested by immature caterpillars, kill them by stopping them from feeding.Which of the following, if true, most strongly supports the view that it would not be advisable to try to eradicate agricultural pests that go through a caterpillar stage by spraying croplands with the enzyme mentioned above?(A) Most species of caterpillar are subject to some natural predation.(B) Many agricultural pests do not go through a caterpillar stage.(C) Many agriculturally beneficial insects go through a caterpillar stage.(D) Since caterpillars of different species emerge at different times, several sprayings would be necessary.(C)(E) Although the enzyme has been synthesized in the laboratory, no large-scale production facilities exist as yet.12. Although aspirin has been proven to eliminate moderate fever associated with some illnesses, many doctors no longer routinely recommend its use for this purpose. A moderate fever stimulates the activity of the bo dy’s disease-fighting white blood cells and also inhibits the growth of many strains of disease-causing bacteria.If the statements above are true, which of the following conclusions is most strongly supported by them?(A) Aspirin, an effective painkiller, alleviates the pain and discomfort of many illnesses.(B) Aspirin can prolong a patient’s illness by eliminating moderate fever helpful in fighting some diseases.(C) Aspirin inhibits the growth of white blood cells, which arenecessary for fighting some illnesses.(D) The more white blood cells a patient’s body produces, the less severe the patient’s illness will be.(B)(E) The focus of modern medicine is on inhibiting the growth of disease-causing bacteria within the body.13. Because postage rates are rising, Home Decorator magazine plans to maximize its profits by reducing by one half the number of issues it publishes each year. The quality of articles, the number of articles published per year, and the subscription price will not change. Market research shows that neither subscribers nor advertisers will be lost if the magazine’s plan is instituted.Which of the following, if true, provides the strongest evidence that the magazine’s profits are likely to decline if the plan is instituted?(A) With the new postage rates, a typical issue under the proposed plan would cost about one-third more to mail than a typical current issue would.(B) The majority of the magazine’s subscribers are less concerned about a possible reduction in the quantity of the magazi ne’s articles than about a possible loss of the current high quality of its articles.(C) Many of the magazine’s long-time subscribers would continue their subscriptions even if the subscription price were increased.(D) Most of the advertisers that purchase advertising space in the magazine will continue to spend the same amount on advertising per issue as they have in the past.(D)(E) Production costs for the magazine are expected to remain stable.14. A study of marital relationships in which one partner’s sleeping and waking cycles differ from those of the other partner reveals that such couples share fewer activities with each other and have more violent arguments than do couples in a relationship in which both partners follow the same sleeping and waking patterns. Thus, mismatched sleeping and waking cycles can seriously jeopardize a marriage.Which of the following, if true, most seriously weakens the argument above?(A) Married couples in which both spouses follow the same sleeping and waking patterns also occasionally have arguments than can jeopardize the couple’s marriage.(B) The sleeping and waking cycles of individuals tend to vary from season to season.(C) The individuals who have sleeping and waking cycles that differ significantly from those of their spouses tend to argue little with colleagues at work.(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses.(D)(E) According to a recent study, most peopl e’s sleeping and waking cycles can be controlled and modified easily.Questions 15-16 are based on the following.Roland: The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.Sharon: But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed. So at any given time if a person knows approximately 50 workers, 1 or more will very likely be unemployed.15. Sharon’s argument is structured to lead to which of the following as a conclusion?(A) The fact that 90% of the people know someone who is unemployed is not an indication that unemployment is abnormally high.(B) The current level of unemployment is not moderate.(C) If at least 5% of workers are unemployed, the result of questioning a representative group of people cannot be the percentage Roland cites.(D) It is unlikely that the people whose statements Roland cites are giving accurate reports.(A)(E) If an unemployment figure is given as a certain percent, the actual percentage of those without jobs is even higher.16. Sharon’s argument relies on the assumption that(A) normal levels of unemployment are rarely exceeded(B) unemployment is not normally concentrated in geographically isolated segments of the population(C) the number of people who each know someone who is unemployed is always higher than 90% of the population(D) Roland is not consciously distorting the statistics he presents(B)(E) knowledge that a personal acquaintance is unemployed generates more fear of losing one’s job than does knowledge of unemployment statistics。

知识模块：逻辑推理16．The population of peregrine falcons declined rapidly during the 1950’s and 1960’s and reached an all-time low in the early 1970’s. The decline was attributed by scientists to the widespread use of the pesticide DDT in rural areas. Which of the following, if true, gives the strongest support to the scientists’ claim?A．DDT was not generally in use in areas devoted to heavy industry.B．In the time since the use of DDT was banned in 1972, the population of peregrine falcons has been steadily increasing.C．Peregrine falcons, like other birds of prey, abandon eggs that have fallen out of the nest, even if the eggs remain intact.D．Starlings, house sparrows, and blue jays-birds the peregrine falcon preys on were not adversely affected by DDT in their habitats.E．Other birds of prey, such as the osprey, the bald eagle, and the brown pelican, are found in the same areas as is the peregrine falcon.正确答案：B解析：本题由“游隼数量快速下降”这一事实，得出一个解释性的结论“DDT 是原因”，属于典型的“B，A”题型的支持，如果自从1972年DDT被禁用以后，游隼数量稳步增加，正如(B)所说，相当于“没有DDT，就没有游隼数量的下降”，即无因就无果。

59. Top college graduates are having more difficulty demonstrating their superiority to prospective employers than did the top students of twenty years ago when an honors degree was distinction enough. Today's employers are less impressed with the honors degree. Twenty years ago no more than 10 percent of a given class graduated with honors. Today, however, because of grade inflation, the honors degree goes to more than 50 percent of a graduating class. Therefore, to restore confidence in the degrees they award, colleges must take steps to control grade inflation. Which one of the following is an assumption that, if true, would support the conclusion in the passage? (A) Today's students are not higher achievers than the students of twenty years ago. (B) Awarding too many honors degrees causes colleges to inflate grades. (C) Today's employers rely on honors ranking in making their hiring decisions. (D) It is not easy for students with low grades to obtain jobs. (E) Colleges must make employers aware of the criteria used to determine who receives an honor degree. 60. One of the more reliable methods of determining regional climatic conditions in prehistoric periods is to examine plant pollen trapped in glacial ice during ancient times. By comparing such pollen samples with spores take from modern vegetation, scientists can figure out approximately what the weather was like at the time of pollen deposition. Furthermore, by submitting the prehistoric samples to radiocarbon dating techniques, we can also determine when certain climatic conditions were prevalent in that portion of the globe. Which one of the following may be inferred from the inFORMation in the passage? (A) The earth has undergone several glacial periods. (B) Radiocarbon dating can be corroborated by glacial evidence. (C) Similarities between prehistoric and contemporary climates do not exist. (D) Pollen deposition is a fairly continuous process. (E) Certain flora are reliably associated with particular climatic conditions. 61. Investigators concluded that human failure was not responsible for the fatal airplane crash last August, and since that time new and more stringent rules for identifying and reporting mechanical problems have been in effect. That accounts for the fact that reports of airplane mechanical problems have increased in frequency by 50 percent since last August. Which one of the following is an assumption underlying the argument in the passage? (A) Airplane travel is still relatively safe, despite the increase in reported mechanical problems. (B) Mechanical problems in airplanes have increased dramatically since last August. (C) Mechanical problems in airplanes have not increased by 50 percent since last August. (D) Airlines are less reluctant to report mechanical problems than they previously were. (E) Mechanical problems in airplanes have become easier to detect since last August. 62. Brushing your teeth regularly no matter which toothpaste you use, will reduce your chances of tooth decay. Scientists have concluded that, when you brush, you reduce tooth decay by removing the film of plaque that FORMs on teeth and gums. So, you can forget about fluorides: brush your teeth carefully and say goodbye to cavities. Which one of the following is a criticism of the reasoning in the argument? (A) Brushing with fluoride toothpaste has been shown to reduce tooth decay. (B) The fact that brushing will reduce tooth decay does not show that fluorides are of no value. (C) Few people adequately remove plaque by brushing. (D) People have plaque on their teeth most of the time. (E) Scientists have been wrong about fluorides. 63. Some good cooks are gourmet cooks who pride themselves on always using extravagantly rich ingredients in elaborate recipes. Some good cooks can be characterized as fast-food cooks. They may use rich ingredients as long as the recipes are easy to follow and take little time. Other good cooks are health food enthusiasts, who are concerned primarily with the nutritional value of food. But even though not all good cooks are big eaters, they all enjoy preparing and serving food. If the inFORMation in the passage is true, which one of the following CANNOT be true? (A) Most good cooks do not use extravagantly rich ingredients. (B) Everyone who enjoys preparing and serving food is a good cook. (C) More good cooks who use extravagantly rich ingredients are big eaters than are good cooks who do not use such ingredients. (D) There are fewer good cooks who enjoy serving and preparing food than there are good cooks who are big eaters. (E) Gourmet cooks, fast-food cooks, and cooks who are health food enthusiasts are all big eaters Questions 64-65 If the city council institutes new parking regulations, city revenues will surely increase, since studies have conclusively shown that, if such parking regulations are put into effect, there is an increase in parking violations, and an increase in parking violations will result in a greater number of parking fines collected. 64. If the statements in the passage are true, which one of the following must also be true? (A) Unless there is an increase in the number of parking violations in the city, city revenues will not increase. (B) If the city council institutes new parking regulations, the council will fall from favor with the citizens. (C) The city council will institute new parking regulations only if an increase in city revenues can be expected to result. (D) If the city council's new regulations cause more parking violators to be ticketed, the city revenues will increase. (E) Unless the city institutes a complex system of parking regulations, the city cannot expect traffic violations to increase. 65. According to advertisements, the higher a suntan lotion's sun protection factor, or SPE, the more protection from sunburn. In order for a suntan lotion to work, however, one has to remember to put it on before going in the sun, put on an adequate amount to cover the skin, and reapply it as needed. Therefore, it really does not matter what SPE a suntan lotion has. Which one of the following best identifies the error in reasoning made in the passage? (A) It is unreasonable to assume that the only purpose of a suntan lotion is to provide protection from sunburn. (B) Because some people get sunburned more easily than other, the fact that there are different SPEs cannot be ignored. (C) It cannot be concluded that the SPEs is not important just because there are requirements for the application of the suntan lotion. (D) It is unreasonable to assume that all suntan lotions required the same application procedures in order to work effectively. (E) There is no reason to assume that manufacturers are unaware that people sometimes forget to apply suntan lotion before going in the sun.。
