The longevity ascribed to Hawaii’s current population is attributable mostly to genetically determined factors |
4 | 他因-其他可能 | Insurance Company X is considering issuing a new policy to cover services required by elderly people who suffer from diseases that afflict the elderly. Premiums for the policy must be low enough to attract customers. | Company X is concerned that the income from the policies would not be sufficient to pay for the claims that would be made. | A. Attracting middle-aged customers unlikely to submit claims for benefits for many years. |
5 | 他因-其他可能 | A program instituted in a particular state allows parents to prepay their children’s future college tuition at current rates. The program then pays the tuition annually for the child at any of the state’s public colleges in which the child enrolls. | Parents should participate in the program as a means of decreasing the cost for their children’s college education. | B. The amount of money accumulated by putting the prepayment funds in an interest-bearing account today will be greater than the total cost of tuition for any of the public colleges when the child enrolls. |
7 | 他因-其他方面 | The ice on the front windshield of the car had formed when moisture condensed during the night. | The ice melted quickly after the car was warmed up the next morning because the defrosting vent, which blows on the front windshield, was turned on full force. | B. Even though no attempt was made to defrost the back window, the ice there melted at the same rate as did the ice on the front windshield. |
9 | 他因-其他方面-根据中心词shy animals | A conservation group in the United States is trying to change the long-standing image of bats as frightening creatures. | The group contends that bats are feared and persecuted solely because they are shy animals that are active only at night. | D. Raccoons and owls are shy and active only at night; yet they are not generally feared and persecuted. |
12 | 断桥。fewer restrictions=〉the more lawyers advertise their services=〉charge less=〉 legal costs will be lower | The fewer restrictions there are on the advertising of legal services, the more lawyers there are who advertise their services, and the lawyers who advertise a specific service usually charge less for that service than lawyers who do not advertise | Therefore, if the state removes any of its current restrictions, such as the one against advertisements that do not specify fee arrangements, overall consumer legal costs will be lower than if the state retains its current restrictions. | E. Most lawyers who advertise specific services do not lower their fees for those services when they begin to advertise. |
14 | 否定前提wear seat belts =〉personal right， Automobile insurance rates for all automobile owners are higher | Opponents of laws that require automobile drivers and passengers to wear seat belts argue that in a free society people have the right to take risks as long as the people do not harm other as a result of taking the risks. | they conclude that it should be each person’s decision whether or not to wear a seat belt. | B. Automobile insurance rates for all automobile owners are higher because of the need to pay for the increased injuries or deaths of people not wearing seat belts. |
18 | 反对结论 | A proposed ordinance requires the installation in new homes of sprinklers automatically triggered by the presence of a fire. | a home builder argued that because more than ninety percent of residential fires are extinguished by a household member, residential sprinklers would only marginally decrease property damage caused by residential fires. | E. The largest proportion of property damage that results from residential fires is caused by fires that start when no household member is present. |
27 | 他因-其他可能 | Red blood cells in which the malarial-fever parasite resides are eliminated from a person’s body after 120 days. | Because the parasite cannot travel to a new generation of red blood cells, any fever that develops in a person more than 120 days after that person has moved to a malaria-free region is not due to the malarial parasite. | D. In some cases, the parasite that causes malarial fever travels to cells of the spleen, which are less frequently eliminated from a person’s body than are red blood cells. |
29 | 他因-其他原因 | The number of people diagnosed as having a certain intestinal disease has dropped significantly in a rural county this year, as compared to last year. | ealth officials attribute this decrease entirely to improved sanitary conditions at water-treatment plants, which made for cleaner water this year and thus reduced the incidence of the disease. | C. Because of a new diagnostic technique, many people who until this year would have been diagnosed as having the intestinal disease are now correctly diagnosed as suffering from intestinal ulcers |
31 | 反对结论 | | Some who favor putting governmental enterprises into private hands suggest that conservation objectives would in general be better served if private environmental groups were put in charge of operating and financing the national park system, which is now run by the government. | A. Those seeking to abolish all restrictions on exploiting the natural resources of the parks might join the private environmental groups as members and eventually take over their leadership |
39 | 反对结论 | Most archaeologists have held that people first reached the Americas less than 20,000 years ago by crossing a land bridge into North America. | But recent discoveries of human shelters in South America dating from 32,000 years ago have led researchers to speculate that people arrived in South America first, after voyaging across the Pacific, and then spread northward. | B. Some North American sites of human habitation predate any sites found in South America. |
41 | 他因-其他方面 | Since the mayor’s publicity campaign for Greenville’s bus service began six months ago, morning automobile traffic into the midtown area of the city has decreased seven percent. During the same period, there has been an equivalent rise in the number of persons riding buses into the midtown area | the mayor’s publicity campaign has convinced many people to leave their cars at home and ride the bus to work. | C. Road reconstruction has greatly reduced the number of lanes available to commuters in major streets leading to the midtown area during the past six months. |
43 | 他因-其他可能 | With the emergence of biotechnology companies, it was feared that they would impose silence about proprietary results on their in–house researchers and their academic consultants. | This constraint, in turn, would slow the development of biological science and engineering. | D. To enhance the companies’ standing in the scientific community, the biotechnology companies encourage employees to publish their results, especially results that are important. |
52 | 他因-其他可能 | For example, seventeen percent of the adults in the United States own jogging shoes, but only forty-five percent of the owners jog more than once a year, and only seventeen percent jog more than once a week. | Most consumers do not get much use out of the sports equipment they purchase. | (C) Many consumers purchase jogging shoes for use in activities other than jogging. |
61 | 反对结论 | | The recent decline in the value of the dollar was triggered by a prediction of slower economic growth in the coming year. But that prediction would not have adversely affected the dollar had it not been for the government’s huge budget deficit, which must therefore be decreased to prevent future currency declines. | (D) Before there was a large budget deficit, predictions of slower economic growth frequently caused declines in the dollar’s value. |
64 | 他因-其他可能 | In fact, the quotas will help “mini-mills” flourish in the United States. Those small domestic mills will take more business from the big American steel mills than would have been taken by the foreign steel mills in the absence of quotas. | The imposition of quotas limiting imported steel will not help the big American steel mills | (E) Domestic “mini-mills” produce low-volume, specialized types of steels that are not produced by the big American steel mills. |
67 | 答案要架桥A greater number of newspapers are sold不等于 better informed about major world events | A greater number of newspapers are sold in Town S than in Town T. | the citizens of Town S are better informed about major world events than are the citizens of Town T. | (E) The average newsstand price of newspapers sold in Town S in lower than the average price of newspapers sold in Town T. |
68 | 反对结论 | A drug that is highly effective in treating many types of infection can, at present, be obtained only from the bark of the ibora, a tree that is quite rare in the wild. It takes the bark of 5,000 tree to make one kilogram of the drug. | It follows, therefore, that continued production of the drug must inevitably lead to the ibora’s extinction. | (D) The ibora can be propagated from cuttings and grown under cultivation. |
70 | 反对结论 | Shelby Industries manufactures and sells the same gauges as Jones Industries. Employee wages account for forty percent of the cost of manufacturing gauges at both Shelby Industries and Jones Industries. Shelby Industries is seeking a competitive advantage over Jones Industries | to promote this end, Shelby Industries should lower employee wages. | (B) Lowering wages would reduce the quality of employee work, and this reduced quality would lead to lowered sales. |
78 | 他因-其他可能 | A group of children of various ages was read stories in which people caused harm, some of those people doing so intentionally, and some accidentally. When asked about appropriate punishments for those who had caused harm, the younger children, unlike the older ones, assigned punishments that did not vary according to whether the harm was done intentionally or accidentally. | Younger children, then, do not regard people’s intentions as relevant to punishment. | (A) In interpreting these stories, the listeners had to draw on a relatively mature sense of human psychology in order to tell whether harm was produced intentionally or accidentally. |
81 | 他因-其他方面 | If the program had been successful, the wholesale price of most illegal drugs would not have dropped substantially in 1987. | The program to control the entry of illegal drugs into the country was a failure in 1987. | (B) domestic production of illegal drugs increased substantially in 1987 |
93 | 否定前提 | Dental researchers recently discovered that tooth-brushes can become contaminated with bacterial that cause pneumonia and strep throat. They found that contamination usually occurs after toothbrushes have been used for four weeks. | For that reason, people should replace their toothbrushes at least once a month. | (C) The dental researchers found that among people who used toothbrushes contaminated with bacterial that cause pneumonia and strep throat, the incidence of these diseases was no higher than among people who used uncontaminated toothbrushes. |
96 | 否定前提-根据free-wheel systems | The difficulty with the proposed high-speed train line is that a used plane can be bought for one-third the price of the train line, and the plane, which is just as fast, can fly anywhere. The train would be a fixed linear system, and we live in a world that is spreading out in all directions and in which consumers choose the free-wheel systems (cars, buses, aircraft), which do not have fixed routes. | Thus a sufficient market for the train will not exist. | C) Planes are not a free-wheel system because they can fly only between airports, which are less convenient for consumers than the high-speed train’s stations would be. |
101 | 他因-其他可能-根据alteration in the intensity of incident light | Biological functions of many plants and animals vary in cycles that are repeated every 24 hours.It is tempting to suppose that alteration in the intensity of incident light is the stimulus that controls these daily biological rhythms. | But there is much evidence to contradict this hypothesis. | (E) Even when exposed to constant light intensity around the clock, some algae display rates of photosynthesis that are much greater during daylight hours than at night. |
102 | 他因-其他可能 | Although migraine headaches are believed to be caused by food allergies, putting patients on diets that eliminate those foods to which the patients have been demonstrated to have allergic migraine reactions frequently does not stop headaches. | Obviously, some other cause of migraine headaches besides food allergies much exist. | (A) Many common foods elicit an allergic response only after several days, making it very difficult to observe links between specific foods patients eat and headaches they develop. |
106 | 他因-其他可能-medical expenses | Treatment for hypertension forestalls certain medical expenses by preventing strokes and heart disease. Yet any money so saved amounts to only one-fourth of the expenditures required to treat the hypertensive population. | there is no economic justification for preventive treatment for hypertension. | (A) The many fatal strokes and heart attacks resulting from untreated hypertension cause insignificant medical expenditures but large economic losses of other sorts. |
110 | 他因-其他可能- repaire | Robot satellites relay important communications and identify weather patterns. Because the satellites can be repaired only in orbit, astronauts are needed to repair them. Without repairs, the satellites would eventually malfunction. | space flights carrying astronauts must continue. | (E) Technical obsolescence of robot satellites makes repairing them more costly and less practical than sending new, improved satellites into orbit. |
111 | 问题是问weaken ….except, 还是和结论相关 | Advocates of a large-scale space-defense research project conclude that it will represent a net benefit to civilian business. | They say that since government-sponsored research will have civilian applications, civilian businesses will reap the rewards of government-developed technology. | (C) Many civilian businesses will receive subcontracts to provide materials and products needed by the research project. |
112 | 他因-其他可能 | In an attempt to promote the widespread use of paper rather than plastic, and thus reduce non biodegradable waster, the council of a small town plans to ban the sale of disposable plastic goods for which substitutes made of paper exist. | The council argues that since most paper is entirely biodegradable, paper goods are environmentally preferable.
| (D) Since most townspeople prefer plastic goods to paper goods in many instances, they are likely to purchase them in neighboring towns where plastic goods are available for sale |
113 | 他因-其他可能 | Since the deregulation of airlines, delays at the nation’s increasingly busy airports have increased by 25 percent. | To combat this problem, more of the takeoff and landing slots at the busiest airports must be allocated to commercial airlines. | (A) The major causes of delays at the nation’s busiest airports are bad weather and overtaxed air traffic control equipment. |
114 | 他因-其他可能，否定前提 | The more frequently employees take time to exercise during working hours each week, the fewer sick days they take. Even employees who exercise only once a week during working hours take less sick time than those who do not exercise. | Therefore, if companies started fitness programs, the absentee rate in those companies would decrease significantly. | (B) Employees who are frequently absent are the least likely to cooperate with or to join a corporate fitness program. |
118 | 他因-其他可能 | According to the Tristate Transportation Authority, making certain improvements to the main commuter rail line would increase ridership dramatically. The authority plans to finance these improvements over the course of five years by raising automobile tolls on the two high-way bridges along the route the rail line serves | Although the proposed improvements are indeed needed, the authority’s plan for securing the necessary funds should be rejected because it would unfairly force drivers to absorb the entire cost of something from which they receive no benefit.
| (D) When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved. |
119 | 他因-其他可能 | 同上 | 同上 | (D) The roads along the route served by the rail line are highly congested and drivers benefit when commuters are diverted from congested roadways to mass transit. |
125 | 他因-wholesale price of raw cotton不等于clothing price | Unlike the wholesale price of raw wool, the wholesale price of raw cotton has fallen considerably in the last year. | although the retail price of cotton clothing at retail clothing stores has not yet fallen, it will inevitably fall. | (A) The cost of processing raw cotton for cloth has increased during the last year. |
131 | 否定前提 | 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. | (B) When the government did not insure deposits, frequent bank failures occurred as a result of depositors' fears of losing money in bank failures. |
132 | 反对结论 | 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. | (A) Test evacuations showed that putting on the smoke hoods added considerably to the overall time it took passengers to leave the cabin. |
136 | 他因-其他可能reducing by one half the number of issues=>advertising cost down to 1/2 if same amount per issue | 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. | (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. |
137 | 因果倒置 | 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. | (D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses. |
141 | 反对结论 | In the past most airline companies minimized aircraft weight to minimize fuel costs. The safest airline seats were heavy, and airlines equipped their planes with few of these seats. | This year the seat that has sold best to airlines has been the safest one—a clear indication that airlines are assigning a higher priority to safe seating than to minimizing fuel costs. | (E) Because of technological innovations, the safest airline seat on the market this year weighed less than most other airline seats on the market |
143 | 反对结论 | Division manager: I want to replace the Microton computers in my division with Vitech computers.
General manager: Why?
Division manager: It costs 28 percent less to train new staff on the Vitech. | General manager: But that is not a good enough reason. We can simply hire only people who already know how to use the Microton computer. | (C) Experienced users of Microton computers command much higher salaries than do prospective employees who have no experience in the use of computers. |
144 | 他因-其他可能 | An airplane engine manufacturer developed a new engine model with safety features lacking in the earlier model, which was still being manufactured. During the first year that both were sold, the earlier model far outsold the new model | the manufacturer thus concluded that safety was not the customers’ primary consideration. | (B) Many customers consider earlier engine models better safety risks than new engine models, since more is usually known about the safety of the earlier models |
146 | 因果倒置 | Firms adopting “profit-related-pay” (PRP) contracts pay wages at levels that vary with the firm’s profits. | In the metalworking industry last year, firms with PRP contracts in place showed productivity per worker on average 13 percent higher than that of their competitors who used more traditional contracts. | (D) Many firms in the metalworking industry have modernized production equipment in the last five years, and most of these introduced PRP contracts at the same time. |
147 | 他因-其他可能 | Crops can be traded on the futures market before they are harvested. If a poor corn harvest is predicted, prices of corn futures rise; if a bountiful corn harvest is predicted, prices of corn futures fall. This morning meteorologists are predicting much-needed rain for the corn-growing region starting tomorrow. | Therefore, since adequate moisture is essential for the current crop’s survival, prices of corn futures will fall sharply today. | (D) Agriculture experts announced today that a disease that has devastated some of the corn crop will spread widely before the end of the growing season. |
154 | 结论中因果倒置 | Start-up companies financed by venture capitalist have a much lower failure rate than companies financed by other means. | Source of financing, therefore, must be a more important causative factor in the success of a start-up company than are such factors as the personal characteristics of the entrepreneur, the quality of strategic planning, or the management structure of the company. | (E) Venture capitalists base their decisions to fund start-up companies on such factors as the
characteristics of the entrepreneur and quality of strategic planning of the company.

157 | 他因-其他可能 | Companies O and P each have the same number of employees who work the same number of hours per week. According to records maintained by each company, the employees of Company O had fewer job-related accidents last year than did the employees of Company P. | Therefore, employees of Company O are less likely to have job-related accidents than are employees of Company P | (B) Company P considered more types of accidents to be job-related than did Company O. |
158 | 他因-其他可能 | In comparison to the standard typewriter keyboard, the EFCO keyboard, which places the most-used keys nearest the typist’s strongest fingers, allows faster typing and results in less fatigue, | Therefore, replacement of standard keyboards with the EFCO keyboard will result in an immediate reduction of typing costs. | (D) The more training and experience an employee has had with the standard keyboard, the more costly it is to train that employee to use the EFCO keyboard. |
163 | 他因-其他可能 | Neighboring Country Y has experienced the same climatic conditions, but while agricultural production has been falling in Country X, it has been rising in Country Y.
| An overly centralized economy, not the changes in the climate, is responsible for the poor agricultural production in Country X since its new government came to power. | (D) The crops that have always been grown in Country X are different from those that have always been grown in Country Y. |
166 | 他因-其他可能 | Last year the rate of inflation was 1.2 percent, but for the current year it has been 4 percent. | We can conclude that inflation is on an upward trend and the rate will be still higher next year. | (B) Last year a dip in oil prices brought inflation temporarily below its recent stable annual level of 4 percent. |
168 | 他因-其他可能 | In the United States in 1986, the average rate of violent crime in states with strict gun-control laws was 645 crimes per 100,000 persons—about 50 percent higher than the average rate in the eleven states where strict gun-control laws have never been passed. | Thus one way to reduce violent crime is to repeal strict gun control laws. | (A) The annual rate of violent crime in states with strict gun-control laws has decreased since the passage of those laws. |
170 | 他因-其他可能 | There is sufficient funding to pay the salaries of the new officers, but not the salaries of additional court and prison employees to process the increased caseload of arrests and convictions that new officers usually generate. | The proposal to hire ten new police officers in Middletown is quite foolish. | (E) Middletown’s ratio of police officers to citizens has reached a level at which an increase in the number of officers will have a deterrent effect on crime. |
176 | 他因-其他可能 | Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested. Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, whose novel aerodynamic design is extremely fuel efficient. | The Skybus’ fuel efficiency results in both lower fuel costs and reduced time spent refueling. | (E) The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs. |
178 | 他因-其他可能 | In countries in which new life-sustaining drugs cannot be patented, such drugs are sold at widely affordable prices; those same drugs, where patented, command premium prices because the patents shield patent-holding manufacturers from competitors. | These facts show that future access to new life-sustaining drugs can be improved if the practice of granting patents on newly developed life-sustaining drugs were to be abolished everywhere. | (D) Pharmaceutical companies can afford the research that goes into the development of new drugs only if patents allow them to earn high profits. |
179 | 他因-其他可能 | A museum has been offered an undocumented statue, supposedly Greek and from the sixth century B.C. Possibly the statue is genuine but undocumented because it was recently unearthed or because it has been privately owned. However, an ancient surface usually has uneven weathering, whereas the surface of this statue has the uniform quality characteristically produced by a chemical bath used by forgers to imitate a weathered surface. | Therefore, the statue is probably a forgery | (C) The chemical bath that forgers use was at one time used by dealers and collectors to remove the splotchy surface appearance of genuinely ancient sculptures. |
180 | 反对结论 | In the arid land along the Colorado River, use of the river’s water supply is strictly controlled: farms along the river each have a limited allocation that they are allowed to use for irrigation. But the trees that grow in narrow strips along the river’s banks also use its water. | if farmers were to remove those trees, more water would be available for crop irrigation. | (A) The trees along the river’s banks shelter it from the sun and wind, thereby greatly reducing the amount of water lost through evaporation. |
182 | 他因-其他可能-对于implements由不同的解释 | The earliest Mayan pottery found at Colha, in Belize, is about 3,000 years old. Recently, however, 4,500-year-old stone agricultural implements were unearthed at colha. These implements resemble Mayan stone implements of a much later period, also found at Colha. Moreover, the implements’ designs are strikingly different from the designs of stone implements produced by other cultures known to have inhabited the area in prehistoric times. | there were surely Mayan settlements in Colha 4,500 years ago | (D) Successor cultures at a given site often adopt the style of agricultural implements used by earlier inhabitants of the same site. |
183 | 他因-其他可能-找有可能export的措施 | Regulations recently imposed by the government of Risemia call for unprecedented reductions in the amounts of pollutants manufacturers are allowed to discharge into the environment. It will take costly new pollution control equipment requiring expensive maintenance to comply with these regulations. Resultant price increases for Risemian manufactured goods will lead to the loss of some export markets. | annual exports of Risemian manufactured goods will in the future occur at diminished levels. | (A) The need to comply with the new regulations will stimulate the development within Risemia of new pollution control equipment for which a strong worldwide demand is likely to emerge. |
186 | 他因-其他可能 | .Offshore oil-drilling operations entail an unavoidable risk of an oil spill, but importing oil on tankers presently entails an even greater such risk per barrel of oil | if we are to reduce the risk of an oil spill without curtailing our use of oil, we must invest more in offshore operations and import less oil on tankers. | (A) Tankers can easily be redesigned so that their use entails less risk of an oil spill. |
187 | 否定前提 | The Highway Traffic Safety Institute reports that the PZ 1000 has the fewest injuries per accident of any car in its class. | This shows that the PZ 1000 is one of the safest cars available today. | (C) Cars in the class to which the PZ 1000 belongs are more likely to be involved in accidents than are other types of cars. |
188 | 他因-其他可能more money是因为 new workers，所以不一定会导致该结果发生。拆桥 | When demand for a factory’s products is high, more money is spent at the factory for safety precautions and machinery maintenance than when demand is low. | Thus the average number of on-the-job accidents per employee each month should be lower during periods when demand is high than when demand is low and less money is available for safety precautions and machinery maintenance. | (B) It s management hires new workers but lacks the time to train them properly. |
191 | 他因-样本没有代表性 | To evaluate a plan to save money on office-space expenditures by having its employees work at home, XYZ Company asked volunteers from its staff to try the arrangement for six months. | During this period, the productivity of these employees was as high as or higher than before. | (A) The employees who agreed to participate in the test of the plan were among the company’s most self-motivated and independent workers. |
192 | 反对结论-因为 根据general impression不能readily distinguished | Mourdet Winery: Danville Winery’s new wine was introduced to compete with our most popular wine, which is sold in a distinctive tall, black bottle. Danville uses a similar bottle. Thus, it is likely that many customers intending to buy our wine will mistakenly buy theirs instead. | Danville Winery: Not so. The two bottles can be readily distinguished: the label on ours, but not on theirs, is gold colored. | (D) It is common for occasional purchasers to buy a bottle of wine on the basis of a general impression of the most obvious feature of the bottle. |
193 | 他因-其他可能-因为 Commercial buildings linked directly to the fire department | The mayor plans to deactivate the city’s fire alarm boxes, because most calls received from them are false alarms. The mayor claims that the alarm boxes are no longer necessary, since most people now have access to either public or private telephone. | But the city’s commercial district, where there is the greatest risk of fire, has few residents and few public telephones, so some alarm boxes are still necessary. | (B) Commercial buildings have automatic fire alarm systems that are linked directly to the fire department. |
194 | 他因-其他可能-方案不可行，反而使成本上升。 | A major impediment to wide acceptance of electric vehicles even on the part of people who use their cars almost exclusively for commuting is the inability to use electric vehicles for occasional extended trips. | In an attempt to make purchasing electric vehicles more attractive to commuters, one electric vehicle producer is planning to offer customers three days free rental of a conventional car for every 1,000 miles that they drive their electric vehicle. | (B) Because a majority of commuters drive at least 100 miles a week, the cost to the producer of making good the offer would add considerably to the already high price of electric vehicles. |
196 | 否定前提-举相反的例子。 | An unusually severe winter occurred in Europe after the continent was blanketed by a blue haze resulting from the eruption of the Laki Volcano in the Europeans republic of Iceland in the summer of 1984. | it is evident that major eruptions cause the atmosphere to become cooler than it would be otherwise. | (C) A few months after EI Chichon’s large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term weather trends. |
198 | 他因-其他可能 | A factory was trying out a new process for producing one of its products, with the goal of reducing production costs. A trial production run using the new process showed a 15 percent reduction in costs compared with past performance using the standard process. | The production managers therefore concluded that the new process did produce a cost savings. | (C) While the trial was being conducted, production costs at the factory for a similar product, produced without benefit of the new process, also showed a 15 percent reduction. |
200 | 他因-其他可能 比如该方法的危害。 | Outsourcing is the practice of obtaining from an independent supplier a product or service that a company has previously provided for itself. | Since a company’s chief objective is to realize the highest possible year-end profits, any product or service that can be obtained from an independent supplier for less than it would cost the company to provide the product or service on its own should be outsourced. | (B) Successful outsourcing requires a company to provide its suppliers with information about its products and plans that can fall into the hands of its competitors and give them a business advantage. |
201 | 因果倒置 | Many businesspeople who have not been to our state believe that we have an inadequate road system. | Those people are mistaken, as is obvious from the fact that in each of the past six years, our state has spent more money per mile on road improvements than any other state. | (E) Only states with seriously inadequate road systems need to spend large amounts of money on road improvements. |
203 | 他因-其他可能 | In physics journals, the number of articles reporting the results of experiments involving particle accelerators was lower last year than it had been in previous years. | Several of the particle accelerators at major research institutions were out of service the year before last for repairs, so it is likely that the low number of articles was due to the decline in availability of particle accelerators. | (E) Recent changes in the editorial policies of several physics journals have decreased the likelihood that articles concerning particle-accelerator research will be accepted for publication. |
