3、satellite-communications technology in recent years are at last yielding benefits for air travelers, particularly executives who need to keep in touch with their offices. Five airlines three of them based in the Asia-Pacific regionhave recently equipped aircraft to offer outbound (向外的)telephone call
4、s to anywhere in the world using a new satellite system. And in the not-too-distant future, businessmen will be able to send faxes in flight, too.Air Canada, Qantas of Australia, United Airlines of the US and Japan Air Lines have at least one satellite-communication aircraft apiece. Hong Kongs Catha
5、y Pacific Airways is also about to offer the service and several other airlines are expected to follow. The calls, dialed directly and charged to a credit card, will cost about US $ 9 10 per minute.The earlier flying phonesPhone communications from aircraft are not entirely new. For some time, telep
6、hones have been available to passengers on US internal flights, for example, and on private jets.But these systems have used cellular phones operating on very high frequency radio links. These systemsthe same links that keep pilots in touch with flight controllershave either limited range or low qua
7、lity and reliability, particularly over vast oceans such as the Pacific. By contrast, the new satellite service will provide clear links instantly to destinations around the world.Technological obstaclesSeveral technological problems had to be resolved before the service could be introduced. One was
8、 to define an effective technical standard, Airinc 741, that guarantees compatibility among different manufacturers avionics systemsessential if the service was to be truly global.Another was to make reliable antennas(天线) small enough and light enough to mount on aircraft of different types. And a t
9、hird was to perfect voice-coding algorithms(规则系统), which tell machinery how to break down voice signals into digital signals for transmission at the standard rate of 9,600 bits a second.A further drawback, for any type of call routed by satellite, is an uncomfortable time lag between words being spo
10、ken and received. Because of the distance that signals have to travel, there is a delay of about a quarter of a second. With airborne calls, there is the potential for a double delay as signals arriving via satellite at a ground station are passed on via another satellite to their destination.To avo
11、id this problem, ground stations have been equipped to identify calls from aircraft and route them to coaxial or fibre-optic cables for the second lag of their journey. Surface links, though long, are still considerably shorter than the 72,000-km round-trip into space. Most calls will therefore not
12、suffer the double delay.The International Maritime Satellite Organization (Inmarsat) approved the initial sitcom system for commercial service last November after two years of trials. Besides the handful of aircraft operated by the five major carriers who have signed on to the system, about two doze
13、n company jets have fitted with the necessary equipment.A new technologyThe technology has three components: antennas and associated equipment on board planes, communications satellites, and ground stations.In the course of development, antennas have lust both their dish shape and several kilograms.
14、 Even so, antenna and avionics weigh as much as two occupied scats. One obstacle to further weight savings, however, is that lighter antennas are more easily confused by the plethora(过多 ) of satellites now circling the Earth.The satellites themselves are provided by Inmarsat, a London-based cooperat
15、ive of 64 nations. One operational satellite and several back-ups cover each of three zones the Atlantic Ocean (East), the Pacific, and the Indian Ocean. A fourth zone, Atlantic Ocean (West), will go into action later this year.Ground stationsThree consortiums(国际财团) are competing for airlines busine
16、ss by setting up ground stations to accept calls bounced off Inmarsat satellites and channel them into telephone networks.Skyphone, comprising British Telecom International, Norwegian Telecom and Singapore Telecom, has worldwide coverage through stations at Goonhilly, England; Elk, Norway; and Singa
17、pore. US satellite corporation Comsat has joined up with Japans international operator, KDD, with ground stations in Yamaguchi, Japan, and Southbury and Santa Paula, on the US East and West Coasts.In addition, the Societe Internationale de Telecommunications Aeronautique, a cooperative owned by airl
18、ines, has combined with Teleglobe Canada; France Telecom and OTC of Australia to create Satellite Aircom, with ground stations in Perth, Australia; Aussaguel, France; Weir, Canada; and Niles Canyon, US.Advantages and prospectsAccording to Hans Karisen, Inmarsats marketing manager for aeronautical (航
19、空的) services, the prospects for aircraft-satellite communications look particularly bright in the booming Asia-Pacific air travel market. Around the region, aircraft are flying full and carriers are better able to afford the roughly US $ 500,000 Cost of equipping each airliner. But many carriers wil
20、l order the equipment only for new aircraft rather than take existing ones out of service for lengthy modifications.Satellite communications will also help improve flight efficiency. A system of voice and data links is already operating between aircraft and their operations centres which, for exampl
21、e, enables crews to obtain permission to change altitudes at the optimum time for fuel efficiency.Crews can also call ahead for maintenance; an aircraft with a vibrating engine, for example, can be met on arrival by engineers who have already obtained computerized data on its behaviour. These commun
22、ications, however, like most existing airborne telephones, mostly use radio links; in the future they, too, will be transferred to the satellite system.The instant nature of the air-to-ground communications will also improve navigation, by allowing continuous reporting of aircraft positions. Indeed,
23、 a study by the International Civil Aviation Organization indicates that the technology could provide benefits worth between US $ 5 6 billion annually in fuel efficiency, faster repair turn-arounds and improved traffic flows through airports.For the fidgety (坐立不安的 ) executive, meanwhile, air travel
24、need no longer mean a communications black-out. And some airlines are already developing data terminals that will permit passengers to change hotel and car-hire reservations, or contact their banks and brokers.2 It is the progresses in satellite-communications technology that make it possible for ai

39、ully for its general idea. When the passage is read for the second time, you are required to fill in the blanks numbered from 36 to 43 with the exact words you have just heard. For blanks numbered from 44 to 46 you are required to fill in the missing information. For these blanks, you can either use
40、 the exact words you have just heard or write down the 29 People tend to be more impressed by evidence that seems to confirm some relationship. Thus many are【B1】_their dreams are prophetic(预言的)because a few have come true; They fail to【B2 】_the many that have not.Consider also the belief that “the p
41、hone always rings when I m in the shower.“ If it does ring while you are in the shower, the event will stand out and be【B3 】_. If it doesnt ring, that non-event probably wont even register(留下印象).People want to see order,【B4】_and meaning in the world. Consider, for example, the【B5】_belief that things
42、 like personal misfortunes, plane crashes, and deaths “happen in threes.“ Such beliefs stem from the【B6 】_of people to allow the third event to【B7】_the time period. If three plane crashes occur in a month, then the period of time that counts as their “happening【B8】_“is one month; if three crashes oc
43、cur in a year, the period of time is stretched.【B9】_.We also tend to believe what we want to believe. A majority of people think they are more intelligent, more fair - minded and more skilled behind the wheel of an automobile than the average person.【B10】_As economist Thomas Schelling explains, “Eve

You are required to select one word for each blank from a list of choices given in a word bank following the
46、 passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item with a single line through the center. You may not use any of the words in the bank more than once.40 Nowadays, it was fashio
47、nable to speak of a generation gap, a【S1】_between young people and their elders. Parents complained that their children did not show them proper respect and【S2】_. while children complained that their parents did not understand them at all. What had gone wrong? Why had the generation gap【S3 】_appeare
48、d? Actually, the generation gap has been around for a long time. Many critics argue that it is built into the fabric of our society.One important cause of the generation gap is the【S4 】_that young people have to choose their own lifestyles. In more【S5 】_societies, when children grow up, they are exp
49、ected to live in the【S6】_area as their parents, to marry people that their parents know and approve of, and often to continue the family occupation. In our society, young people often travel great distances for their education, move out of the family home at an early age, marry or live with people whom their parents have never【 S7】_. and choose occupations different from those of their parents.In our modern s
