单选题 General Wesley Clark recently discovered a hole in his personal security—his cell phone. A resourceful blogger, hoping to call attention to the black market in phone records, made his privacy-rights experiment on the general in January. For $ 89.95, he purchased, no questions asked, the records of 100 cell-phone calls that Clark had made. (He revealed the trick to Clark soon after.) "It's like someone taking your wallet or knowing who paid you money", Clark says. "It's no great discovery, but it just doesn't feel right." Since then, Clark has become a vocal supporter of the movement to outlaw the sale of cell-phone records to third parties. The U.S.'s embrace of mobile phones—about 65% of the population are subscribers—has far outpaced efforts to keep what we do with them private. That has cleared the way for a cottage industry devoted to exploiting phone numbers, calling records and even the locations of unsuspecting subscribers for profit. A second business segment is developing applications like anonymous traffic monitoring and employee tracking. Most mobile phones are powerful tracking devices, with global-positioning systems (GPS) inside. Companies like Xora combine GPS data with information about users to create practical applications. One similar technology allows rental-car companies to track their cars with GPS. California imposed restrictions on the practice last year after a company fined a customer $ 3,000 for crossing into Nevada, violating the rental contract. Other applications have not yet been challenged. For about $ 26 a month per employee, a boss can set up a "geofence" to track how workers use company-issued cell phones or even if they go home early. About 1,000 employers use the service, developed by Xora with Sprint-Nextel. The companies selling those services insist that they care about privacy. AirSage, for example, gets data from wireless carriers to monitor drivers' cell-phone signals and map them over road grids. That lets it see exactly where gridlock is forming and quickly alert drivers to delays and alternative routes. The data it gets from wireless carrier companies are aggregated from many users and scrambled, so no one can track an individual phone. "No official can use the data to give someone a speeding ticket", says Cy Smith, CEO of AirSage. Privacy advocates say that even with those safeguards, consumers should have a choice about how their information is used. Some responsibility, of course, rests with the individual. Since his data were revealed, Clark took his mobile number off his business cards. Wireless carriers also recommend that customers avoid giving out their mobile numbers online. But Clark insists that the law should change to protect our privacy, no matter how much technology allows us to connect." One thing we value in this country", he says, "is the freedom to be left alone."

单选题Soon after his appointment as secretary-general of the United Nations in 1997, Kofi Annan lamented that he was being accused of failing to reform the world body in six weeks. "But what are you complaining about.9" asked the Russian ambassador. "You've had more time than God." Ah, Mr. Annan quipped hack, "but God had one big advantage. He worked alone without a General Assembly, a Security Council and [all] the committees. " Recounting that anecdote to journalists in New York this week, Mr. Annan sought to explain why a draft declaration on UN reform and tackling world poverty, clue to be endorsed by some 150 heads of state and government at a world summit in the city on September 14th - 16th, had turned into such a pale shadow of the proposals that he himself had put forward in March. "With 191 member states", he sighed, "it's not easy to get an agreement." Most countries put the blame on the United States, in the form of its abrasive new ambassador, John Bolton, for insisting at the end of August on hundreds of last-minute amendments and a line-by-line renegotiation of a text most others had thought was almost settled. But a group of middle-income developing nations, including Pakistan, Cuba, Iran, Egypt, Syria and Venezuela, also came up with plenty of last-minute changes of their own. The risk of having no document at all, and thus nothing for the world's leaders to come to New York for, was averted only by marathon all-night and aii-weekend talks. The35-page final document is not wholly devoid of substance. It calls for the creation of a Peacebuilding Commission to supervise the reconstruction of countries after wars; the replacement of the discredited UN Commission on Human Rights by a supposedly tougher Human Rights Council; the recognition of a new "responsibility to protect" people from genocide and other atrocities when national authorities fail to take action, including, if necessary, by force; and an "early" reform of the Security Council. Although much pared down, all these proposals have at least survived. Others have not. Either they proved so contentious that they were omitted altogether, such as the sections on disarmament and non-proliferation and the International Criminal Court, or they were watered down to little more than empty platitudes. The important section on collective security and the use of force no longer even mentions the vexed issue of pre-emptive strikes; meanwhile the section on terrorism condemns it "in all its forms and manifestations, committed by whomever, wherever and for whatever purposes", but fails to provide the clear definition the Americans wanted. Both Mr. Annan and, more surprisingly, George Bush have nevertheless sought to put a good face on things, with Mr. Annan describing the summit document as "an important step forward" and Mr. Bush saying the UN had taken "the first steps" towards reform. Mr. Annan and Mr. Bolton are determined to go a lot further. It is now up to the General Assembly to flesh out the document's skeleton proposals and propose new ones. But its chances of success appear slim.

单选题{{B}}Text 4{{/B}} Everyday some 16m barrels of oil leave the Gulf through the Strait of Hormuz. That is enough to fill a soft-drink can for everyone on earth, or to power every motor vehicle on the planet for 25 miles (40kin). Gulf oil accounts for 40% of global trade in the sticky stuff. More important, it makes up two-thirds of known deposits. Whereas at present production rates the rest of the world's oil reserves will last for a mere 25 years, the Gulf's will last for 100. In other words, the region's strategic importance is set to grow and grow. Or at least so goes the conventional wisdom, which is usually rounded out with scary talk of unstable supplies, spendthrift regimes and a potential fundamentalist menace. Yet all those numbers come with caveats. A great deal of oil is consumed by the countries that produce it rather than traded, so in reality the Gulf accounts for less than a quarter of the world's daily consumption. As for reserves, the figures are as changeable as a mirage in the desert. The most comprehensive research available, conducted by the US Geological Survey, refers to an "expected" total volume for global hydrocarbon deposits that is about double current known reserves. Using that figure, and throwing in natural gas along with oil, it appears that the Gulf contains a more moderate 30% or so of the planet's future fossil-fuel supplies. Leaving out the two Gulf states that are not covered in this survey--Iran and Iraq--the remaining six between them hold something like 20% of world hydrocarbon reserves, not much more than Russia. All the same, {{U}}it is still a hefty chunk;{{/U}} enough, you might think, to keep the people living atop the wells in comfort for the foreseeable future. But you might be wrong. At present, the nations of the Gulf Cooperation Council have a combined national income roughly equal to Switzerland's, but a population which, at around 30m, is more than four times as big. It is also the fastest-growing on earth, having increased at nine times the Swiss rate over the past quarter-century. Meanwhile the region's share of world oil trade has fallen, as has the average price per barrel. As a result, the income per person generated by GCC oil exports has been diminishing since the 1970s. True, surging demand from America and Asia has recently boosted the Gulf's share of trade, but the medium-term outlook for oil pries remains weak. Combined with continued growth in oil consumption, this should create sustained upward pressure on prices. And high oil prices will speed the search for alternatives. Who knows, in 20 years' time fuel cells and hydrogen power may have started to become commercial propositions.
