单选题{{B}}Passage One{{/B}} Men are happier with money, while women find greater joy in friendships and relationships with their children, co-workers and bosses, a new global survey reveals. The online survey of 28,153 people in more than 51 countries by global marketing and information firm Nielsen found that as the world grapples(努力解决) with a recession and financial markets remain volatile(反复无常), many people are reminding themselves that money can't buy happiness. The Nielsen Happiness Study found that globally, women are happier than men in 48 of the 51 countries surveyed in April 2008, and only in Brazil, South Africa and Vietnam were men found to be happier than women. "Because they are happier with non-economic factors, women's happiness is more recession-proof which might explain why women around the world are happier in general than men are," Nielsen Vice President of Consumer Research Bruce Paul said in a statement. Japanese women reported the greatest difference and are 15 percent happier than Japanese men. Women are also more optimistic about the future, scoring higher than men on predictions of their happiness in the next six months. Men are generally happier with their physical health than women, and this is especially pronounced in South Africa. Egypt bucks(相反，相对立)the trend, with women rating their happiness with their health considerably higher than men. Globally, men rated their happiness with their mental health higher than women. This was echoed in Belgium, South Korea, Mexico, Norway, Spain, Sweden, Egypt, and Israel. As well as measuring levels of happiness, the Nielsen survey examined what specific factors contributed to happiness around the world. "Happiness is a local and personal matter and Nielsen sought to uncover what specific factors contribute to making people happy in different parts of the world," Paul said. "Many of the world's poorer and emerging markets outranked developed countries for happiness and satisfaction levels in nearly ail aspects of their lives." Nielsen also looked closely at survey results to find out if a nation's happiness level was influenced by low income inequality, low corruption or peace. Surprisingly, markets which performed poorly on these factors were in many cases the happiest nations, Paul said. "For consumers in rapidly developing markets, there could be a greater sense of appreciation for things that bring a better life than they had a few years ago."

单选题The Internet, perhaps the most important technological development of the past 30 years, succeeded unexpectedly. It started out in an experimental backwater, nurtured far from the mainstream. It was spawned with no business plan and with no CEO leading the charge. Instead, a group of researchers—nerds, really—had the very unentrepreneurial idea to develop a set of free and open technical protocols to move data from one place to another. The PC, which I think of as a companion technology to the Internet, likewise groomed as the hobbyhorse of passionate nerds who (at least initially) shared their designs. Both the Internet and the PC were released unfinished, and because they were open technologies, businesses and inventors could use them as a springboard for innovation. New applications were deployed to use them without needing the permission of their vendors. This kind of openness isn't found in cars, fridges, Video or any other major technology. It's what helped the Internet and PC succeed over more boring, predictable counterparts—proprietary networks like CompuServe and information appliances like dedicated smart word processors. However, now that PCs and the Internet have become mainstream tools, there's rising pressure to turn them into the appliances they defeated: to close them, in some cases forbidding outside tinkering altogether, and in others allowing it only under closely monitored and controlled circumstances. The Internet and the PC as well-springs of innovation are living on borrowed time. The new closed models that represent the likely future of consumer computing and networking are no minor tweaks. We face wholesale revision of the Internet and PC environment of the past several decades. The change is coming partly because of the need to address security problems peculiar to open technologies, and partly because businesses want more control over the experience that customers have with their products. The trend from open systems toward closed ones threatens the culture of serendipitous tinkering that has given us the Web, instant messaging, peer-to-peer networking, Skype, Wikipedia and a host of other innovations, each of which emerged from left field. It will produce a concentrated set of new gatekeepers, with us and them prisoner to their limited business plans and to regulators who fear things that are new and disruptive.

单选题It was time to get creative. In 2006, a head of government had signed a law requiring that greenhouse gases be cut 20 percent below 1990 levels by 2020 and 80 percent by 2050. The cuts will be carried out through a cap-and-trade system, like the one passed by the House of Representatives and introduced in the Senate, due to start in 2012. In an effort to reduce the cost of those greenhouse cuts, the executive reached out to his counterparts in Brazil and Indonesia, which have more than half of the world's remaining tropical forests. Because reducing deforestation is the cheapest way to mitigate climate change in the short term, he wanted utilities and other greenhouse emitters to be able to pay state governments in Brazil and Indonesia to preserve their forests, which ranchers and loggers keep whacking (砍劈), yielding the same net gain for the atmosphere as reducing their own emissions of carbon dioxide. The details—how to measure the CO2 cuts, how much to pay for preserving forests—will be worked out in the next few months, in time to set the rules for cap-and-trade. The official is Gov. Arnold Schwarzenegger of California, and his bilateral agreements with counterparts from Amazonas, Papua, and six other states in Brazil and Indonesia with millions of hectares of tropical forests illustrate why the impending failure to reach a new global climate accord isn't the disaster it might have been. Think "subnational". Although the 192 countries set to meet in Copenhagen next month will not reach a legally binding treaty setting out targets for greenhouse-gas reductions starting in 2012, cities, states, and provinces are on track to cut greenhouse gases. They see it as a way to retool their economies, draw high-paying jobs, and establish the industries of tomorrow, leapfrogging the sclerotic (僵化的) global talks. California's partnerships, for instance, will be the first time tropical forests are corralled (包围) into an international agreement. Not even the 1997 Kyoto climate treaty which requires wealthy countries to reduce their emissions of six greenhouse gases 5.2 percent from 1990 levels, does that. "We will definitely keep moving ahead," says Anthony Brunello, California's deputy secretary for climate and energy. That's the promise not only from states and provinces but also from businesses, especially those placing big bets on renewable energy and technologies to boost energy effeciency. Which raises a question that makes climate activists uneasy: why, exactly, was the Copenhagen meeting painted as the do-or-die moment—"the most important meeting since the end of the second world war", one green group called it—for averting calamitous climate change? Seeing the failure of Copenhagen as something short of Armageddon is not contrarianism for contrarianism's sake. Just to be clear, if the world had agreed on what quantity of greenhouse-gas emissions to cut by when—on "targets and timetables", in the prevailing argot (行话)—it would have launched us down a path that could keep global warming below 2 degrees Celsius, relative to pre-industrial levels, which many climate scientists see as a point of no return. The meltdown of global climate talks is therefore a setback to efforts to avert the worst consequences of global warming.
