The tail wheel undercarriage dominated aircraft design for the first four decades of flight and is still widely used on many small piston-engine planes. What makes this form of landing gear most attractive is its simplicity. Another potential advantage results from the fact that _Part II Reading Comprehension（30%）Section 1 Skimming and Scanning (10%)Directions: In this section there are 10 incomplete statements. Based on the following passage, please complete the statements with the information given in the passage. Commercial aviation is an essential component of the global economy. The cost of aviation fuel is directly determined by the prevailing world price of oil, and it accounts for a major proportion of airplane operating costs. Several airline companies now add a fuel surcharge to the ticket cost of a commercial flight to compensate for the recent rapid rise in fuel costs. World oil prices are expected to remain high for several years. The prospect of sustained high aviation fuel prices could propel airline companies to seek alternative aviation fuels. Seeking alternative fuel could become paramount（最高的） for the airline industry should the peak-oil phenomenon actually occur. Breakthroughs and Research It may become possible for super-cooled liquid hydrogen（氢） to eventually be used as an alternative fuel for some types of commercial airline service. Other alternative fuels may include high-density energy-storage technologies that result from breakthroughs in research in the areas of nanotechnology(纳米技术) and in high-temperature superconductivity(超导性). High-temperature superconductivity holds great promise for use in high-density energy-storage technology. Advances in nanotechnology could enable superconductive materials to eventually be manufactured at a cost that could justify their application in airliner propulsion. Electrical Storage and PropulsionEnergy stored in a superconductive storage technology could power electric motors that drive the identical propulsion fans that are found at the front-end of modern, “high-bypass” turbo-fan aircraft engines. Such fans provide up to 90% of the propulsive thrust of the turbo-fan engine. Each electrically powered propulsion fan may be driven by multiple (induction) lightweight electric motors during take-off. Some electric motors would “cut-out” under reduced power demand at cruising altitude so that the remaining motors will operate at higher efficiency (electric motors have poor part-load efficiency). Coanda fans may propel subsonic commercial aircraft that use high-density electrical storage technology. Such units were originally developed by physicist Henri Coanda and can operate at comparable efficiency and at comparable flight speeds as turbine-driven propulsion fans. Electrically powered aircraft that use either turbine propulsion fans or Coanda fans could be flown in thinner air at higher altitude (up to 65,000-feet) to reduce energy consumption (less drag on aircraft) on extended flights. The cooler air found at such altitudes could assist in keeping the superconductive energy storage systems functioning properly. Superconductive energy storage systems used in future commercial aircraft would likely be cooled by liquid nitrogen(氮). Both systems would need to be frequently recharged, which would likely be both energy-intensive as well as time consuming. It may be possible to design the energy storage systems along with their cooling systems to be removed and replaced during shorts layoverssuch technology could help reduce the turn-around time of the aircraft. The introduction of superconductive energy storage systems in commercial aircraft in the long-term future would require that future airport terminals be equipped with power generation technology at or near the premises. Power GenerationThe number of electrically powered and hydrogen powered road and railway vehicles would likely increase during a post peak-oil period. Commuter aircraft that operate short-haul service could be powered by ethanol(乙醇) or by hydrogen while future supersonic aircraft could use liquid hydrogen as fuel. The commercial aviation industry of the future (post peak oil) could likely require vast amounts of electric power to recharge superconductive energy storage systems, recharge liquid nitrogen cooling systems as well as to generate, compress and supercool large amounts of hydrogen. Modern commercial aircraft are energy intensive during take-off. Airports that serve metropolitan areas presently process continual processions of large long-distance aircraft during peak periods. Such aircraft could require between 300-Mw-hr and 1000-Mw-hr of power to undertake trans-oceanic flights at subsonic speed. The power requirements of a future electrically based commercial aviation industry could likely overwhelm the power generation industry of most developed nations. Major international airports may eventually need to generate electric power on-site to meet the energy needs of future fleets of electrically powered and hydrogen-fueled commercial aircraft. Airport power stations may be nuclear; use hydrogen fusion or be based on some other unconventional power generation technology that is still subject to research. Energy StorageThe ability to store large amounts of energy at or near major airports could gain importance during a post peak-oil period. Electric power could be purchased from the grid during their off-peak periods and put into short-term storage. Airport power stations that encounter off-peak periods could replenish(装满) airport energy storage systems that may include superconductive storage, flow batteries, hydraulic storage in hydroelectric dams in nearby mountains (coastal airports) or off-site pneumatic storage (subterranean salt domes that were emptied). Air that is exhausted from pneumatic storage systems may be sufficiently cold to assist in “replenishing” liquid nitrogen super-cooling systems.Power Regulation (Airports)Power stations that provide energy for air transportation use may have to be excluded from the regulatory framework. Most of the electrically powered airliners that will be recharged would be “foreign” owned, that is, the owners would be domiciled in a different jurisdiction(司法权) to where the aircraft would be recharged. The idea of regulators in one jurisdiction looking after the interests of parties who live, do business and pay taxes in another jurisdiction is quite ludicrous. Power stations that supply a future airline industry with electric power would need to be regulatory-free despite the “foreign” airline owners being “captive” customers. It would be possible for power to be supplied to a single airport by several small providers who compete against each other. Power providers and airline companies could negotiate deals, perhaps even on a daily basis. ConclusionFuture scientific breakthroughs are likely to occur in both nanotechnology and in superconductivity. High-density energy storage technologies could be the likely result and appear in the distant future. Electrically powered commercial aircraft that fly at subsonic speeds could appear in the future irrespective of whether or not peak-oil actually occurs. Alternative liquid fuels that are cost-competitive to fossil oil are also likely to appear and find applications in aviation. Large ground-effect aircraft（地效飞行器） that fly above water and that carry either passengers or freight between coastal cities are also likely appear in the future.1.

Section 2 Reading Comprehension (10%)Directions: The following passage is followed by some questions. For each of them there are four choices marked A), B), C) and D). You should choose the best answer from the four choices.Living standards have soared during the twentieth century, and economists expect them to continue rising in the decades ahead. Does that mean that we humans can look forward to increasing Happiness? Not necessarily, warns Richard A. Easterlin, an economist at the University of Southern California, in his new book, Growth Triumphant: The Twenty-first Century in Historical Perspective. Easterlin concedes that richer people are more likely to report themselves as being happy than poorer people are. But steady improvements in the American economy have not been accompanied by steady increases in peoples self-assessments of their own Happiness. The explanation for this paradox(悖论) may be that people become less satisfied over time with a given level of income. In Easterlins word: “As incomes rise, the aspiration level does too, and the effect of this increase in aspirations is to vitiate (破坏) the expected growth in Happiness due to higher income.”Money can buy Happiness, Easterlin seems to be saying, but only if ones amounts get bigger and other people arent getting more. His analysis helps to explain sociologist Lee Rainwaters finding that Americans perception of the income “necessary to get along” rose between 1950 and 1986 in the same proportion as actual per capita income. We feel rich if we have more than our neighbors, poor if we have less, and feeling relatively well-off is equated with being happy.Easterlins findings, challenge psychologist Abraham Maslows “hierarchy(等级) of wants” as a reliable guide to future human motivation. Maslow suggested that as peoples basic material wants are satisfied they seek to achieve nonmaterial or spiritual goals. But Easterlins evidence points to the persistence of materialism. “Despite a general level of affluence never before realized in the history of the world.” Easterlin observes, “Material concerns in the wealthiest nations today are as pressing as ever and the pursuit of material need as intense.” The evidence suggests there is no evolution toward higher order goals. Rather, each step upward on the ladder of economic development merely stimulates new economic desires that lead the chase ever onward. Needs are limited, but not greeds. Science has developed no cure for envy, so our wealth boosts our Happiness only briefly while shrinking that of our neighbors. Thus the outlook for the future is gloomy in Easterlins view. “The triumph of economic growth is not a triumph of humanity over material wants; rather, it is the triumph of material wants over humanity.”1. What does Easterlin warn in his new book? A) Humans can look forward to increasing happiness with soaring living standards.B) Humans might not be able to enjoy increasing happiness with soaring living standards. C) Richer people tend to report themselves as being happy more than poorer people do.D) Richer people tend to report themselves as being happy less than poorer people do. 2. Which of the following statements may account for the paradox(悖论) mentioned in paragraph 3?A) People become less satisfied though the income rises over time.B) A general level of affluence never before realized in the history of the world.C) Though the American economy improved steadily, there isnt a steady increase in peoples self-assessments of their own happiness.D) As incomes rise, there will be an increase in the aspira
