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 Propulsion
Energy 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 layovers—such 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 Generation
The 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. power
