The Flying Phone Box A surprise for air travelers The strides made in 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 region—have recently equipped aircraft to offer outbound (向外的)telephone calls 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 Kong’s Cathay 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 phones Phone communications from aircraft are not entirely new. For some time, telephones 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 systems—the same links that keep pilots in touch with
flight controllers—have either limited range or low quality 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 obstacles Several technological problems had to be resolved before the service could be introduced. One was to define an effective technical standard, Airinc 741, that guarantees compatibility among different manufacturers’ avionics systems—essential 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 third 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 spoken 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 avoid 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 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 dozen company jets have fitted with the necessary equipment.
A new technology The 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. 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 cooperative 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 stations Three consortiums(国际财团) are competing for airlines’ business 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 Singapore. US satellite corporation Comsat has joined up with Japan’s 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 airlines, 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 prospects According
to Hans Karisen, Inmarsat’s marketing manager for aeronautical (航空的) 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 will 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 example, 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 communications, 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, 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 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.

听力原文： A significant effort will be waged this year to bring more state-owned land used for non-agricultural purposes into paid land-use contract which will boost land available for agriculture. These lease or contracts agreements will regulate land use while bringing the State income that went uncollected previously. To avert the misuse or loss of State land during the transformation, the State Land Administration (SLA) and its local agencies will appraise land use rights before contracting leases, share purchases or other usage agreements. This effort will not only add to the State revenue and improve the management of the land, but will ensure the best use of land resources and control its redistribution. Over the past year, some 714,000 hectares of cultivated land have been taken over by industrial and residential development, 14% more than in the previous year. The figure matched the 1992 total, the worst year of China’s farmland shrinkage in the last five years.

听力原文：There are over 3,000 languages that are used throughout the world today. Almost all of these languages belong to a much smaller number of language families. All of the languages within a language family are related and all of them have a similar history. Therefore, the grammar, vocabulary, and sounds of related languages ate similar. In addition, the way of thinking and the style of talking among related languages is similar. Even though there are over 3,000 languages that are used today, there are only 20 or 30 major language families. Each of these large families includes many individual languages. The language that we are using now is English and English is, of course, a member of a larger language family. English is a member of the Indo-European language family. The Indo-European language family includes most of the languages that are spoken throughout Europe, languages such as English, French, and Greek. Of course, nowadays many Indo-European languages are spoken in other parts of the world. For instance, Spanish, which is an Indo-European language, is spoken throughout South and Central America, but originally it was spoken only in Europe.

听力原文：The World Health Organization is to call for strict controls on junk food in a major campaign against obesity, and the agency will unveil its actual strategy next week. Based on evidence obtained through various investigations, the WHO believes that obesity has become a global epidemic that is directly associated with more than 30 million deaths each year. According to the agency, obesity is now one of the world’s three greatest health threats, along with smoking and malnutrition. Recent estimates suggest that 1.7 billion people are now obese, which has led to a surge in diseases such as cancers and diabetes. The WHO will call for heavy cuts in the use of sugar, salt and saturated fats. And this is bound to sound the alarm to many of Britain’s top-selling brands, including Cadbury’s, Coca-Cola, and Birds Eye. The WHO will produce a policy paper calling for new daily limits for sugar, salt and fats, as well as tougher control of food advertising. According to the figures issued by the WHO, the safety threshold for sugar would be 10gms a day—a limit already exceeded by one 500ml bottle of cola and, salt should be limited to 5gms a day—the amount of salt contained in a standard tin of baked beans.

Nowadays, it was fashionable 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】______appeared? 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 expected 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 society, parents often expect their children to do better than they did; to find better jobs, to make more money, and to do all the things that they were unable to do. But often they discover that they have very little in【S8】______with each other. The speed at which changes take place in our society is【S9】______cause of the gap between the generations. In a traditional culture, elderly people are valued for their wisdom, but in our society the knowledge of a lifetime may become out of date【S10】______.
