12、 works on a 5-year-plan basis, and they are about to (7) _ the 12th 5-year-plan which runs from 2011 to 2015. The A350 deliveries that we can offer are now in the what will become the 13th 5-year-plan period.”Eric Chen, Airbus Chinas Vice President, adds that the Chinese carriers timid (8) _ to the

13、A350 is due to its competing product, Boeings 787. “Several years ago, Chinese airlines ordered more than 60 Boeing 787s and for various reasons, airlines lack this kind of courage and determination to be a launching customer for a new program again. In other words, we are buying the bill for our ri

You will hear them ONLY ONCE. In each of the

16、se passages some of the sentences are already printed. You are required to translate the missing parts into Chinese. After each of the passages there will be a pause lasting one and a half minutes. The pause is intended for you to do the translation. 1) The ARJ21-700 jetliner, Chinas first self-desi

17、gned aircraft, will undertake its maiden flight before the end of the year. COMAC chairman, Zhang Qingwei says this first homegrown regional jet has aroused great interest from aviation companies at home and abroad.” I just came back from the United States and Canada. _.”2) Nine top tier US manufact

18、uring companies won competitive contracts to build and supply the aviation system for Chinas new aircraft program, the C919. Airport infrastructure needs are filling opportunities in the US companies as well. _3) The Deputy Chief of the Chinas Civic Aviation Administration, Xia Xinghua, says more co

19、operation is crucial for the Chinese side. “Firstly, we need to strengthen our cooperation on sustainable security development, expanding the relationship in a pragmatic way._”4) The Transportation Secretary Ray LaHood said that the review would be comprehensive covering design, manufacturing and as

20、sembly of the Dreamliner. Michael Huerta of the Federal Aviation Administration said emphasis would be put on electrical systems and how these and the planes sophisticated mechanical systems interact._.5) Though the tricycle arrangement may be most popular today, that was not always the case. The ta

21、il 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 Comprehen

22、sion（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 avi

23、ation 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 pr

24、ices 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. Brea

25、kthroughs 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

26、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

27、 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 fan

28、s 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

29、 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

30、 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

31、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, whic

32、h 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 sup

33、erconductive 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

34、 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 vas

35、t 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 p

36、resently 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 c

37、ould 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

38、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 purch

39、ased 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 moun

40、tains (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 e

41、nergy 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 id

42、ea 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 b

43、eing “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 o

44、ccur 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）
