单选题Motorola Inc., the world's second-largest mobile phone maker, will begin selling all of the technology needed to build 'a basic mobile phone to outside manufacturers, in a key change of strategy. The inventor of the cell phone, which has been troubled by missteps compounded by a recent industry slump in sales, is trying to become a neutral provider of mobile technology to rivals, with an eye toward fostering a much larger market than it could create itself. The Chicago area-based company, considered to have the widest range of technologies needed to build a phone, said it planned to make available chips, a design layout for the computer board, software, development tools and testing tools. Motorola has previously supplied mobile phone manufacturers with a couple of its chips, but this is the first time the company will offer its entire line of chips as well as a detailed blueprint. Mobile phones contain a variety of chips and components to control power, sound and amplification. Analysts said they liked the new strategy but were cautious about whether Motorola's mobile phone competitors would want to buy the technology from a rival. The company, long known for its top-notch (等级) engineering culture, is hoping to profit from its mobile phone technology now that the basic technology to build a mobile phone has largely become a commodity. Motorola said it will begin offering the technology based on the next-generation GPRS (Global Packet Radio Service) standard because most mobile phone makers already have technology in place for current digital phones. GPRS offers faster access to data through "always on" network connections, and customers are charged only for the information they retrieve, rather than the length of download. Burgess said the new business will not conflict with Motorola's own mobile phone business because the latter will remain competitive by offering advanced features and designs. Motorola's phones have been criticized as being too complicated and expensive to manufacture, but Burgess said Motorola will simplify the technology in the phones by a third. In addition to basic technology, Burgess said, Motorola would also offer additional features such as Bluetooth, a technology that allows wireless communications at a short distance, and Global Positioning System, which tracks the user's whereabouts, and MP3 audio capability.

单选题1 The period of adolescence, i.e. , the period between childhood and adulthood, may be long or short depending on social expectations and on society's definition as to what constitutes maturity and adulthood. In primitive societies adolescence was frequently a relatively short period of time, while in industrial society with patterns of prolonged education coupled with laws against child labor, the period of adolescence is much longer and may include most of the second decade of one's life. Furthermore, the length of the adolescent period and the definition of adulthood status may change in a given society as social and eco- nomic conditions change. Examples of this type of change are the disappearance of the fron- tier in the latter part of the nineteenth century in the United States, and more universally, the industrialization of an agricultural society. In modern society, ceremonies for adolescence have lost their formal recognition and symbolic significance and there no longer is agreement as to what constitutes initiation ceremonies. Social ones have been replaced by a sequence of steps that lead to increased recog- nition and social status. For example, grade school graduation, high school graduation and college graduation constitute such a sequence, and while each step implies certain behavioral changes and social recognition, the significance of each depends on the socio-economic status and the educational ambition of the individual. Ceremonies for adolescence have also been replaced by legal definitions of status, roles, rights, privileges and responsibilities. It is during the nine years from the twelfth birthday to the twenty-first that the protective and restrictive aspects of childhood and minor status are removed and adult privileges and responsibilities are granted. The twelve-year-old is no longer considered a child and has to pay full fare for train, airplane, theater and movie tickets. Basically, the individual at this age loses childhood privileges without gaining significant adult rights. At the age of sixteen the adolescent is granted certain adult rights which increase his social status by pro- viding him with more freedom and choices. He now can obtain a driver's license; he can leave public schools; and he can work without the restrictions of child labor laws. At the age of eighteen the law provides adult responsibilities as well as rights. The young man can now be a soldier, but he also can marry without parental permission. At the age of twenty-one the individual obtains his full legal rights as adult. He now can vote, he can buy liquor, he can enter into financial contracts, and he is entitled to run for pubic office. No additional basic rights are acquired as a function of age after maturity status has been attained. None of these legal provisions determine at what points adulthood has been reached but they do point to the prolonged period of adolescence.

单选题Farmers in the developing world hate price fluctuations. It makes it hard to plan ahead. But most of them have little choice: they sell at the price the market sets. Farmers in Europe, the U. S. and Japan are luckier: they receive massive government subsidies in the form of guaranteed prices or direct handouts. Last month U. S. President Bush signed a new farm bill that gives American farmers $ 190 billion over the next 10 years, or $83 billion more than they had been scheduled to get, and pushes U. S. agricultural support close to crazy European levels. Bush said the step is necessary to " promote farmer independence and preserve the farm way of life for generations". It is also designed to help the Republican Party win control of the Senate in November's mid-term elections. Agricultural production in most poor countries accounts for up to 50% of GDP, compared to only 3% in rich countries. But most farmers in poor countries grow just enough for themselves and their families. Those who try exporting to the West find their goods whacked with huge tariffs or competing against cheaper subsidized goods. In 1999 the United Nations Conference on Trade and Development concluded that for each dollar developing countries receive in aid they lose up to $ 14 just because of trade barriers imposed on the export of their manufactured goods. It's not as if the developing world wants any favours, says Uganda's Minister of Finance. "What we want is for the rich countries to let us complete. " Agriculture is one of the few areas in which the Third World can compete. Land and labour are cheap, and as farming methods develop, new technologies should improve output. This is no pie-in-the-sky speculation. The biggest success in Kenya's economy over the past decade has been the boom in exports of cut flowers and vegetables to Europe. But that may all change in 2008, when Kenya will be slightly too rich to qualify for the " least-developed country" status that allows African producers to avoid paying stiff European import duties on selected agricultural products. With trade barriers in place, the horticulture industry in Kenya will shrivel as quickly as a discarded rose. And while agriculture exports remain the great hope for poor countries, reducing trade barriers in other sectors also works: American's African Growth and Opportunity Act, which cuts duties on exports of everything from handicrafts to shoes, has proven a boon to Africa's manufacturers. The lesson: the Third World can prosper if the rich world gives it a fair go. This is what makes Bush's decision to increase farm subsidies last month all the more depressing. Poor countries have long suspected that the rich world urges trade liberalization only so it can wangle its way into new markets. Such suspicions caused the Seattle trade talks to break down three years ago. But last November members of the World Trade Organization, meeting in Doha, Qatar, finally agreed to a new round of talks designed to open up global trade in agriculture and textiles. Rich countries assured poor countries, that their concerns were finally being addressed. Bush's Handout last month makes a lie of America's commitment to those talks and his personal devotion to free trade.
