Bus 59. But as fuel prices rose, the school district needed to find a way to cut its transportation costs. So the schools busing company redrew its route map, eliminating Nias bus altogether. Now Nia and her neighbors travel the half mile to school via a "walking school bus" —a group of kids, supervised by an adult or two, who make the walk together. Like the rest of us, school districts are feeling pinched by rising fuel costs—and finding new way to adapt. The price of diesel fuel has gone up 34 percent in the past two years. For the typical American school district, bus bills total 5 percent of the budget. As administrators look to trim, busing is an inviting target, since it doesnt affect classroom instruction (or test scores). More than one third of American school administrators have eliminated bus stops or routes in order to stay within budget. Many parents are delighted to see their kids walking to school, partly because many did so themselves: according to a 1969 survey, nearly half of school kids walked or biked to school, compared with only 16 percent in 2001. Modern parents have been unwilling to let kids walk to school for fear of traffic, crime or simple bullying, but with organized adult supervision, those concerns have diminished. Schools and busing companies are finding other ways to save. In rural areas where busing is a must, some schools have even chosen four-day school weeks. Busing companies instruct drivers to eliminate extra stops from routes and to turn off the engine while idling. They are also using computer software to determine the most fuel-efficient routes, which arent always the shortest ones. There could be downsides, however, to the busing cutbacks. If every formerly bused student begins walking to school, its an environmental win—but if too many of their parents decide to drive them instead, the overall carbon footprint can grow. Replacing buses with many more parent-driven cars can also increase safety risks. A 2002 report concluded students are 13 times safer on a school bus than in a passenger car, since buses have fewer accidents and withstand them better due to their size. And some students complain about the long morning hikes, particularly when the route contains a really big hill.

The "walking school bus" ______.

A．does not consume fuel

B．aims to keep children fit

C．seldom causes traffic jams

D．is popular with school kids

ate-change plan spells out in detail how much pain each of its 27 members will have to beat if the EU is to meet ambitious targets set by national leaders last March. The aim is to cut greenhouse-gas emissions by 2020 by at least a fifth, and more than double to 20% the amount of energy produced from renewable sources such as wind or wave power. If fuel from plants proves green enough, 10% of the fuel used in transport must come from biofuels by the same date. The new plan turns these goals into national targets. This will surely start much grumbling and months of horse-trading, as the European Commissions recommendations are turned into binding law by national governments and the European Parliament. Countries with greenery in their veins are being asked to take more of the burden uian newer members. Sweden, for example, is being invited to meet 49% of its energy from renewables. At the other end, Malta gets a renewables target of just 10%. It is a similar story when it comes to cutting greenhouse gases; by 2020, Denmark must cut emissions by 20% from 2005 levels; Bulgaria and Romania, the newest members, may let their emissions rise by 20%. EU leadership on climate change will not come cheap. The direct costs alone may be 60 billion ($ 87 billion) , or about 0.5% of total EU GDP, by 2020, said the commissions president, Jose Manuel Barroso. But this is still presented as a bargain compared with the cost of inaction , which Mr. Barroso put at ten times as high. "Oh, leading the world in the fight against climate change need not cost jobs. Even in the most heavily polluting branches of heavy industry. We want to keep out industry in Europe," insisted Mr. Barroso. The trick to achieve the seemingly impossible targets is the EU s emissions-trading scheme (ETS). This obliges big polluters such as power companies or manufacturing giants to trade permits that allow them to emit CO2 and other climate-change nasties, within a steadily tightening overall cap. If countries such as the US do not sign binding international agreements by 2001, then the heaviest greenhouse-gas emitters inside the EU may be given these allowances free, the commission suggests. Or, it threatens, firms to buy ETS permits.

To its member nations, the EU s plan means_____.

A．a fierce competition

B．an ideal goal

C．a good opportunity

D．a difficult task

The new aircraft will be______to a test of temperatures of-65 °C and 120 °C
