"We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations," Obama said. The President pointed out that recent severe weather supplied an urgent impetus for energy innovation and staked the nations economic future on responding to a changing climate. "We cannot cede to other nations the technology that will power new jobs and new industries--we must claim its promise," Obama said. " Thats how we will maintain our economic vitality and our national treasure--our forests and waterways; our croplands and snowcapped (山顶积雪的) peaks. That is how we will preserve our planet, commanded to our care by God. " So what could the President reasonably do to deliver on that vow？ Here are ten of their suggestions: Sunset coal with new incentives and regulations. [B] "Provide incentives to phase out the oldest, most polluting power plants," said Robert Jackson, a climate scientist at Duke University. Its already happening, to some degree, as more of the nation transitions to natural gas. Earth scientist Bill Chameides, dean of Dukes Nicholas School of the Environment and a former chief scientist at the Environmental Defense Fund, urges the administration to use its Clean, Air Act authority to promulgate (颁布 )carbon regulations for existing power plants like it has for new ones: "Doing that will force fuel switching from coal to natural gas. "Invest federal stimulus money in nuclear power. [C] Its hardly a perfect fuel, as accidents like Japans Fukushima fallout have shown, but with safety precautions new nuclear plants can meaningfully offset dirtier types of energy, supporters say."Nuclear is the only short-to medium-term way to really get away from fossil fuels," said Peter Raven. President emeritus of the Missouri Botanical Garden. He said the damage done by relentless global warming will far exceed the damage done by faults in the nuclear system. Kill the Keystone pipeline. [D] The controversial Keystone XL oil pipeline is up for review again by the White House this year. "The fn~t thing he should do to set the tone to a lower carbon economy is to reject the Keystone pipeline,"said Raymond Pierrehumbert, a geophysical scientist at the University of Chicago. The pipeline was never going to be a major driver of global emissions, but Pierrehumbert and some other environmentalists say that by killing it the President would send a clear message about Americas intent to ramp down fossil fuels. Protect the oceans by executive order. [E] Land use is complicated, but large swaths of oceans can be protected by executive order. Just as President George W. Bush designated the worlds largest marine monument northwest of Hawaii in 2006. Obama could single-handedly protect other areas. National Geographic Explorer-in-Residence Sylvia Earle said the President should focus on parts of the Arctic that are under U. S. control, putting them off limits to energy production, commercial fishing, and mineral exploration. Marine sanctuaries (禁捕区) wont stop climate change, but they can give marine species a better chance of adapting to it by reducing the other man-made threats the animals face. Experiment with capturing carbon. [F] Huge untapped reserves of natural gas and oil make it unlikely that the U. S. will transition away from fossil fuels in the immediate future. Instead, said Wallace Broecker, geology professor at Columbia Universitys Lamont-Doherty Earth Observatory, we should attack the atmospheres carbon surplus directly. "Obama could make available funds to build and test prototype air capture units" to capture and store CO2, said Broecker. Removing some carbon from the atmosphere could buy valuable time as policy makers and scientists explore more permanent solutions. Grow government research for new energy sources. [G] The Department of Energy has a nimble program thats tasked with innovative energy research—the Advanced Research Projects Agency-Energy. The ARPA-E funds research in biofuels, transmission,and battery storage, with an annual budget of $ 275 million. Last year, DOE officials requested at least $ 75 million more. Increasing funding for ARPA-E, said Rare Pomerance, former deputy assistant secretary of state for environment and development and currently an environmental consultant, "you get new technologies that undercut coal, oil, and gas. " Plus, he said, yon get a competitive advantage if American researchers uncover the next big idea in new energy. Tax carbon. [H] Congress would have to agree, but many climate experts say that the most meaningful way to tackle emissions is to set a price on carbon. "We should be asking people to pay the cost of putting carbon into the atmosphere as they buy the fuel," said Josh Willis, climate scientist and oceanographer at NASAs Jet Propulsion Laboratory. To gain political support for the idea, Obama would probably have to show that the tax wonld help accelerate technology, grow new industries, and pay down the deficit. Dial back the federal governments energy use. [I] With more than I. 8 million employees, $ 500 billion in annual purchasing power, and 500,000 buildings to operate, the federal government has been a leader in reducing energy use since Obama signed a 2009 executive order to cut waste. "I would urge him to keep using the power of government to promote energy conservation," said Syndonia Bret-Harte, an Arctic biologist who studies climate change at the University of Alaska, Fairbanks. Build a scientific clearinghouse for climate information. [J] "I advocate for building a better information system on what is happening and why," said Kevin Trenberth, head of the Climate Analysis Section at the U. S. National Center for Atmospheric Research. That involves compiling observations related to climate change from around the world and using the data to refine climate modeling. Think of it as a one-stop, user-friendly website that clearly demonstrates how weather data from around the globe are influenced by broader shifts in the planets climate. Keep talking. Despite a consensus among top scientists, the world still needs some convincing on climate change. [K] A CNN poll last week found that just 49 percent of Americans agree that global warming is real and is due to human activities. "The most important thing the President can do is to build on his inaugural comments to heighten the sense of urgency about rapid climate destabilization and clarify its connection to virtually every other issue on the national agenda," said David Orr, environmental studies professor at Oberlin College. That means using the bully clergymen to show how a more volatile climate affects everything from agriculture to transportation to 21st-century warfare. The urge to promulgate carbon regulations is aimed at pushing power plants to replace coal by natural gas.

Questions 下列各 are based on the following passage. A recent BBC documentary, The Town That Never Retired, sought to show the effects of increasing the state pension age by putting retirees back to work. Although the results were entertaining, they need not have bothered. Away from the cameras, unprecedented numbers of older people are staying in work .Since the start of the recession that began in 2008, the number of 16-to 24-year-olds in work has fallen by 597,000. Over the same period the number of workers over the age of 65 has increased by 240 o000. The greying of the British workforce dates back to around 2001, since when the proportion of older people working has nearly doubled. But it has accelerated since the start of the recession. There are several reasons why. Happily, people are living longer and healthier lives, which makes staying in work less daunting than it was. Less happily, low interest rates, a stagnant stock market and the end of many defined-benefit (固定收益 ) pension schemes make it a financial necessity. And changing attitudes ,spurred by rules against age discrimination, are making it easier than ever. Most older workers are simply hanging on at the office: 63% of workers over state pension age have been with their employer for more than ten years. Over two-thirds of them work part-time, mostly doing jobs that they once performed full-time. A big advantage is that they do not pay national insurance contributions effectively a second income tax on younger workers. According to Stephen McNair, director of the Centre for Research into the Older Workforce, this flexibility explains why older workers have not suffered so much in the slump. Instead of slashing the workforce, as in previous recessions, many firms have halted recruitment and cut working hours. At small businesses in particular, keeping on older workers is cheaper and less risky than training replacements.Over half of workers over state pension age work for businesses with fewer than 25 employees. Christopher Nieper, who owns David Nieper, a womenswear manufacturer based in Derbyshire,prizes his semi-retired workers, who can be employed at short notice and do not need to work full-time to survive. Retired machinists can fill in if there is a surge in orders; former sales advisers can work as part-time consultants. As his competitors have moved production abroad, depleting the pool of trained labour, retaining older workers and their skills has become even more important. There is scope for the older workforce to expand. Workers over the age of 50 who are made unemployed find it harder to pick up new jobs, which could mean that more oldsters want to work than are able to. That would be good. The Office for Budget Responsibility, the fiscal watchdog, reported on July 12th that an ageing, unproductive population is the biggest long-term threat to Britains economic health. Data from the OECD, a think-tank, shows that employment rates among workers approaching retirement age are split in Europe, with old workers hanging on best in the north. Government credit ratings follow a similar pattern. That Britains ageing workforce more closely resembles Germanys than Italys could prove the countrys salvation(拯救). Which of the following can be inferred from the BBC documentary The Town That Never Retired？
A.What it intends to reveal is contrary to the reality.
B.It has received good comments from audience.
C.It aims to criticize the poor pension provision in the UK.
D.It reflects the current phenomenon of retirees coming back to work.
