单选题{{B}}Passage Three{{/B}} The wandering ship was a dramatic symbol for a problem plaguing our age. In 1987, the ship, loaded with thousands of tons of New York garbage, spent weeks wandering from one port to another in search of a dump before finally returning home, mission unaccomplished. New York, like other communities throughout the world is running out of space to put its trash. As throwaway societies, the US and other industrialized countries expect their garbage to be picked up by trucks that magically transported the refuse to some out-of-sight incinerator(焚化炉) or dump. But in the developing counties of Asia, Africa and Latin America, thousands of tons of trash collected daily are thrown into open dumps, where it feeds huge populations of rats that swarm through poor neighborhoods. "The world is literally swimming in garbage," says a scientist. "Communities worldwide are being forced to confront the problem." Green Peace spokesman Bryan Bence adds, "The crisis in garbage stems in part from the fact that we've ignored long-term disposal problem in favor of cheap quick fixes." The garbage glut (过剩) has inspired many communities in the U.S., Japan and Western Europe to start recycling programs. Once considered a curious counter culture activity recycling has moved firmly into the mainstream. Recycling involves separating usable products from trash, processing them so they can be substituted for more expensive raw materials and returning them to the marketplace as parts of new products. Many countries now have mandatory recycling programs, and others plan to follow the trend soon. Most notably, Japan has stood out as a model and leader of the waste management trend, recycling an estimated 65 percent of its waste. "That's what we should do, to the garbage crisis", says David Antonioli, a staff member with the New York Public Interest Research Corp. "The earth is not a dump!"

单选题Remember global warming? Back in December, the threat of climate change was thundering, and the rich countries agreed to cut their carbon-dioxide and other green-house-related emissions. Since then, interest has cooled markedly, and many European countries are already running away from the promises they made so loudly a few months ago. But there has been much talk, and a bit of action, to encourage renewable (可更新的) energies such as wind, hydro, solar and all living organisms. These emit no greenhouse gases, but tend to cost more than coal, oil or gas. The better, simpler idea is to remember that the easiest way to reduce something is to tax it—in this case, by taxing the carbon content of power. The dirtier the power, the more tax it would pay. So dirty coal would be more expensive than clean coal, which would see its price rise in relation to oil, which would be even more expensive compared to gas, which would lose some of its price advantage over renewables. Unless a carbon tax was so huge as to be economically crippling, it would not remove the price differential (差别) between all renewables and fossil fuels. But it would narrow that gap, by fixing the differing environmental costs into the price—a useful principle in itself. It would also give renewable producers a strong incentive to cut costs, and fossil-fuel suppliers an motivation to clean their products. Precedents suggest strongly that a carbon tax would be effective. But the disadvantage to carbon taxes is political. After almost a decade of trying, the European Union gave up an attempt at a European carbon tax last year. Germany's ruling coalition is fighting against a proposed energy tax. In America, politicians believe that even mentioning the notion is certain death. But many of the political objections could be met if a carbon tax were made up for the loss elsewhere, for example by lowering payroll or sales taxes. There is always suspicion when governments come up with clever new ways to tax, and rightly so. The response to that suspicion should be to win the argument, not to abandon it.
