问答题US Environmental Protection While the G8 summit was under way, and once the news of Wednesday’s London bombings became known, the American president George Bush was widely quoted on the subject of international terrorism. He spoke of his resolve to bring the perpetrators to justice, and to “spread an ideology of hope and compassion that will overwhelm” what he called “their ideology of hate”. But as the G8 meeting drew to a close, the US President had rather less to say about the Plan of Action, announced by the world leaders, to tackle what they deemed the serious and long-term challenge of climate change. Stephen Evans, who’s on a driving tour of the western United States, says many Americans remain unconvinced that this is an issue they need to take seriously: I’ve just driven down from Salt Lake City, through the desert of Utah and Nevada. It is a magnificent sublime wilderness where horizons are wide when they’re not broken by the craggy splendour of an ancient volcanic landscape. As the sun sinks here, the rocks glow red and it’s hard to imagine a threat to the environment where space seems limitless. And yet, many of these escarpments hide sites where humans dispose of all sorts of waste. Just beyond the beauty is a land being violated. This is where America throws its trash over the back wall. In Europe, insurance premiums rise as homes get built on flood plains in a search for every inch of exploitable space. In America, there is not this connection between wallets and weather. Extremes of climate seem natural. Only on the crowded coasts is the environment an issue. California and New York have tough regulations. In between, they often can’t see what the fuss is about. It’s a big country they feel. The taxi-driver in Texas who told me that global warming was hokum is not a lone voice, some of the big oil companies that lobby Mr. Bush are also loathe to concede a link between their product and climate change. The environment sometimes seems like the fashionable issue of the moment, the right badge to wear, the current political designer label. Things are changing though. Neo-conservatives are worried that importing oil means relying on hostile regimes, which, moreover, might funnel some of the dollars to anti-American causes— what the neocons call a terrorism tax on the American people. So there is pressure on Mr. Bush over the environment but not as a grand cause. It’s a concern rather about importing an expensive fuel from hostile places. And Mr. Bush may respond with tax incentives for cleaner technology that the US market seems increasingly to want.

问答题扶贫开发 二十一世纪中国扶贫(poverty alleviation；poverty relief；aiding the poor)开发面临的难点和比较突出的问题是：第一，虽然贫困人13的收入水平明显提高，但目前中国扶贫的标准是低水平的。第二，由于受自然条件恶劣、社会保障系统(social insurance system)薄弱和自身综合能力差等因素的掣肘，目前已经解决温饱问题的贫困人口还存在很大的脆弱性，容易重新返回到贫困状态。第三，尽管扶贫开发已使广大农村贫困地区的贫穷落后状况明显改变，但贫困农户的基本生产生活条件还没有质的变化，贫困地区社会、经济、文化落后的状况还没有根本改观。第四，由于中国人口基数很大，在今后相当长的一个时期将面临就业压力，这必然会影响到贫困人口的就业，使很多本来能够奏效的扶贫措施难以发挥出应有的作用。第五，尚未解决温饱(have enough to eat and wear)的贫困人口一般都生活在自然条件恶劣、社会发展程度低和社会服务水平差的地区，这些地区投入与产出效益的反差较大。

问答题重视儿童肥胖问题 如今，由于肥胖，年轻人正受到像糖尿病等一些潜在的病魔的折磨。伦敦卫生及热带医学学院的安德鲁．普伦蒂斯(Andrew Prentice)教授认为，高脂肪的快餐饮食，加上电视和电脑使得孩子们养成了久坐不动的生活方式，极有可能大大缩短年轻一代的寿命。 与此同时，人类的体形正在发生着革命性的变化，因为成人正越长越胖。最新的研究表明，1972年，英国男性的平均腰围仅为32.6英寸，目前是36～38英寸。而女性的平均腰围则从1920年的22英寸增加到50年代的24英寸，现在，则是30英寸。 仅仅在英国，就有100多万l6岁以下的儿童被归为超重或者肥胖一族，比80年代中期多了一倍。每10个4岁的孩子中就有1个有医学上的肥胖症。这股源于美国的肥胖风已经传遍了欧洲、澳大利亚、美洲中部和中东。目前许多国家记录在案的医学肥胖者有20%，而超重人口已经占到总人数的一半以上。 普伦蒂斯教授说，导致我们体形变化的原因是，高热量食物随手可得，而科技的发展使得人们每天消耗的热量却大大减少。

问答题Is There Life on Mars? The American space agency, NASA (the National Aeronautics and Space Administration), has drawn up a short list of ten research projects that will form the basic of an ambitious program to explore the planet Mars in a mission scheduled for launch in 2007. Scientists are being asked to use their ingenuity to devise novel ways to explore the red planet using intelligent robots and probes that might perhaps answer the biggest question of all—-is there life on Mars? NASA chose the ten projects from a list of 43 hopefuls. It has included missions for returning samples of Martian dust and gas to Earth, networks of small landers, orbiting constellations of microprobes and a rover that would try to date the precise age of rocks and soils. The ten concepts are part of the Mars Scout program to be launched in six years. This follows a decade of the most intensive interest in Mars since the two Viking probes of 1976 which sent back eerie images of the Martian landscape some 400 million kilometers away. But the history of Mars exploration is littered with failure—more than half of the 30 missions to date have ended in fiasco. It was NASA’s announcement in August 1996 of possible signs of life in a Martian meteorite which had fallen to Earth that rekindled intense interest in Earth’s nearest neighbor. It was assumed that liquid water had once flowed on Mars and an ancient atmosphere might have supported living organisms. However, opposing camps of scientists bitterly disputed NASA’s evidence for primitive life-forms in the Martian meteorite ALH84001. This led to the conclusion that the only way of finding out whether life ever existed on Mars is to go there and have a look. NASA planned a bold series of increasingly complex missions involving the launch of a couple of space probes every year for a dozen years. One of the most successful so far was the shoe-box-sized So-journer rover which thrilled a world Internet audience when it was wheeled out in 1997. Since then, however, NASA has suffered a series of setbacks. In September 1999 its Mars Climate Orbiter was lost as a failed rocket bum plunged it into the Martian atmosphere. NASA blamed it on one of its team using imperial units and another using metric. Three months later, NASA lost contact with its Polar Lander as it approached touchdown on the frozen South Pole of the planet. Space commentators muttered darkly about Mars being a cosmic equivalent of the Bermuda triangle. The year of 2001 saw the successful completion of the Global Surveyor mission, an orbiting probe that took pictures of what some scientists say are channels in the dust where water may still occasionally flow from underground well. More recently, the Mars Odyssey probe was launched without hitch and is due to arrive in 2008. Meanwhile, the European Space Agency is planning its own visit to the red planet with the launch of its Mars Express mission scheduled for take-off in .June 2003. Britain is designated to take a lead role in the project with the Beagle 2 Lander, a small craft, the size of a kitchen sink designed to shuffle over the Martian landscape taking soil and rock samples, analyzing them for signs of life and transmitting the data back to Earth. Beagle 2—framed after the ship that carded Charles Darwin on his voyage of discovery—will weigh just 60 kilograms and will cost about US $225,000 to build, a fraction of the cost of building the Viking space probes more than 25 years ago. Beagle 2 will look for water, minerals and organic matter. Although it will reach Mars before NASA’s Scout mission is even launched, it will be considerably less sophisticated in tea’ms of analytical technology. The focus now for NASA is on what instruments and robots to put on the Mars Scout mission in six years. Ed Weiler, NASA’s associate administrator for space science, had to decide on a top ten to concentrate NASA’s limited resources. Each project is to receive a grant of $150,000 to see them through the next six months of development. It all has to come out of a total project budget capped at $300 million. These Scout concepts embody the spirit I first thought about more than a year ago; and will enable us to explore the diversity of Mars in new ways, Dr Weiler said.
