单选题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{{B}}Passage One{{/B}} Gravity is a slippery beast. We don't know how strong it is, how it works or how fast its effects move. But this year we made progress. October saw the most accurate measurement yet of Newton's gravitational constant(引力常数 ), G, a measure of the strength of the gravitational interaction between two objects. A Swiss team calculated G's value by measuring how the gravitational pull of two huge tanks of mercury affected the weights of test masses. However, there are discrepancies between measurements of G made in different labs. This year a highly contentious(有争议的) explanation for this was proposed. A group of string theorists proposed that gravity is subtly affected by magnetic fields, and that G should be larger near Earth's poles where the magnetic field is stronger. Sure enough, this fits with the measurements so far. So G's varying values might just be the first proof of the hidden dimensions predicted by string theory. Equally tantalising is possible evidence for the existence of gravitational waves, the ripples in space-time supposedly caused by abrupt, violent cosmic events. An Italian team reported that two massive aluminium bars, one at CERN(欧洲粒子物理研究所) near Geneva, the other in Italy, had once vibrated in unison(一致)—perhaps as a result of a passing gravitational wave, they suggest. The claims will be closely scrutinised by gravity researchers in Washington state. They got to turn on a very expensive toy this year. LIGO, one of the biggest scientific instruments ever built. Its twin sets of intersecting 4-kilometre-long laser beams should be very sensitive to any waves. But so far the $400-million machine has not seen anything. At least one gravitational mystery has (hopefully) been wrapped up this year. when you move something, how long before its new position will affect its gravitational pull on surrounding objects? In other words, what is the speed of gravity? Newton thought the effect instantaneous, but Einstein said it could travel no faster than the speed of light. Astronomers have finally devised a way to test which one of them was right, based on the way gravity bends radio waves from a distant quasar(类星体). They finished the experiment in September. We don't yet know the answer but our money is on Einstein.
