While consumers pay for perceived shortages at the pump, scientists and economists struggle to reach consensus over "proven oil reserves," or how much oil you can realistically mine before recovery costs outstrip profits. Economist Leonardo Maugeri fired up the debate that accused the "oil doomsters" of crying wolf. Oil pessimists estimate that maximum oil production around the globe will peak in 2008 as demand rises from developing economies such as China. "If you squeezed all the oil in Iraq into a single bottle, you could fill four glasses, with the world consuming one glass of oil each year," says a physicist. "We've consumed nine bottles since oil was discovered, and we have another 9 or 10 in the refrigerator. How many more are there？ Some say five or six, but we say three." Others believe, like Maugeri, that the number of glasses is virtually limitless. John Felmy, chief economist at the American Petroleum Institute, argues that peak oil-production estimates are so far off that. "Ever since oil was first harvested in the 1800s, people have said we'd run out of the stuff," Felmy says. In the 1880s a Standard Oil executive sold off shares in the company out of fear that its reserves were close to drying up. Some scientists said in the 1970s that we'd hit peak oil in 2003. It didn't happen. If there is an end to the debate, advanced oil-recovery technologies will most likely find it. A new seismic survey technique, for instance, sends sound waves of varying frequencies thousands of meters belowground. Microphones arrayed aboveground record the reflected signals, and computer software models a 3-D portrait of possible oil hot spots. The surveys have now added a fourth dimension, creating a time-lapse simulation of fluid movements. Companies are also finding sophisticated ways to mine more oil from existing wells. Flexible, coiled-tube drills that carve out horizontal side paths are a marked improvement over conventional, rigid drills that move only straight down. Using such technology, companies hope to soon harvest 50 to 60 percent of oil from existing wells, up from today's 35 percent. Biotechnology, too is keeping the black gold flowing. University of Albert scientists are searching for microorganisms that could dilute viscous, hard-to-recover oil and make it flow more freely. "Technology can help push peak oil production further and further out," says an expert. But only time will tell when oil production will peak. According to the passage, which of the following statements is true？ A．How long the oil age will last is simply an academic question. B．The oil price this year set a new record. C．Shell Group reduced its reserves to 4.5 billion barrels this year. D．Economists disagree with one another on how much oil you can realistically mine.

【77】 Instead of trying to make gradual changes in small increments, make big changes. After all, big changes are relatively easier to make than are small ones. Some people assume that the way to bring about improvement is to make the change small enough so that nobody will notice it. This approach has never worked, and one can' t help but wonder why such thinking continues. Everyone knows how to resist small changes; they do it all the time. If, however, the change is big enough, resistance can' t be mobilized against it.【78】 Management can make a sweeping organizational change, but just let a manager, try to change someone' s desk from here to there, and see the great difficulty he encounters. All change is resisted, so the question is how can the changes be made big enough so that they have a chance of succeeding？ Buck Minster Fuller has said that instead of reforms society needs new forms; e. g. , in order to reduce traffic accidents, improve automobiles and highways instead of trying to improve drivers. The same concept should be applied to human relations. There' s a need to think in terms of social architecture, and to provide arrangements among people that evoke what they really want to see in them selves.【79】 Mankind takes great pains with physical architecture, and is beginning to concern it self with the design of systems in which the human being is a component. But most of these designs are only for safety, efficiency, or productivity. System designs are not made to affect those aspects of life people care most about such as family life, romance, and esthetic experiences.【80】 Social technology as well as physical technology need to be applied in making human arrangements that will transcend anything mankind has yet experienced. People need not be victimized by their environments; they can be fulfilled by them. (76)

Florida's E-school attracts many students who need flexible scheduling, from young tennis stars and young musicians to brothers Tobias and Tyler Heeb, who take turns working on the computer while helping out. with their family's clam-farming business on Pine Island, off Florida's southwest coast. Home-schoolers also are well represented. Most students live in Florida, but 55 hail from West Virginia, where a severe teacher shortage makes it hard for many students to take advanced classes. Seven kids from Texas and four from Shanghai round out the student body. The great majority of Florida Virtual Schoolers—80 percent—are enrolled in regular Florida public or private high schools. Some are busy overachievers. Others are retaking classes they barely passed the first time. The school's biggest challenge is making sure that students aren't left to sink or swim on their own. After the school experienced a disappointing course completion rate of just 50 percent in its early years,Executive Director Julie Young made a priority out of what she calls "relationship-building," asking teachers to stay in frequent E-mail and phone contact with their students. That personal touch has helped. The completion rate is now 80 percent. Critics of online classes say that while they may have a limited place, they are a poor substitute for the face-to-face contact and socialization that take place in brick-and-mortar classrooms. Despite opportunities for online chats, some virtual students say they'd prefer to have more interaction with their peers. Students and parents are quick to acknowledge that virtual schooling isn't for everyone. "If your child's not focused and motivated, I can only imagine it would be a nightmare," says Patricia Haygood of Orlando, whose two daughters are thriving at the Florida school. For those who have what it takes, however, virtual learning fills an important niche. "I can work at my own pace, on my own time," says Hackney. "It's the ultimate in student responsibility."
