| 第3题：Global energy demand is expected to triple by mid-century. The earth is unlikely to run out of fossil fuels by then, given its vast reserves of coal, but it seems unthinkable that we will continue to use them as we do now. It’s not just a question of supply and price, or even of the disease caused by filthy air. The terrorist assault on the World TradeCenter raises other scary scenarios: how much easier would it be to crack open the Trans-Alaska pipeline and how much deadlier would it be to bomb a nuclear plant than to attack a wind arm Skeptics may recall the burst of enthusiasm for conservation and renewable power when oil prices quadrupled in the 1970s. State-funded energy research and development surged, while tax incentives boosted solar, wind and other alternatives to petroleum and the atom.But when oil supplies loosened and prices dropped in the early 1990s, governments lost interest. In the state ofCalifornia, subsidies evaporated, pushing wind companies into bankruptcy. Clean energy has long way to go. Only 2.2% of the world’s energy comes from "new" renewables such as small hydroelectric dams, wind, solar and geothermal. How to boost that share--and at what pace--is debated in industrialized nations--from Japan, which imports 99.7 % of its oil, to Germany, where the nearbyChernobyl accident turned the public against nuclear plants, to the U.S., where theBushAdministration has strong ties to the oil industry.But the momentum toward clean renewables is undeniable. How soon we reach an era of clean, inexhaustible energy depends on technology. Solar and wind energies are intermittent: When the sky is cloudy or the breeze dies down, fossil fuel or nuclear plants must kick into compensate.But scientists are working on better ways to store electricity from renewable sources. While developed nations debate how to fuel their power plants, however, some 1.6 billion people--a quarter of the globe’s population--have no access to electricity or gasoline. Many spend their days collecting firewood and cow dung, burning it in primitive stoves that belch smoke into their lungs. To emerge from poverty, they need modern energy.And renewables can help. From village-scale hydropower to household photovoltaic systems to bio-gas stoves that convert dung into fuel. Ultimately, the earth can meet its energy needs without fouling the environment. "But it won’t happen," asserts Thomas Johansson, an energy adviser to the United NationsDevelopment Program, "without political will." To begin with, widespread government subsidies for fossil fuels and nuclear energy must be dismantled to level the playing field for renewables. Moreover, government should pressure utility to meet targets for renewable sources of energy. The author’s biggest worry about using nuclear energy is that ______. A、it will do great harm to the inadequate reserves of coal B、it is deadly if terrorists attack a nuclear plant C、it will limit the development of many other alternatives D、there will be a wider gap between developed and developing countries |

| 第4题：虽然世界市场上供应的一部分象牙来自被非法捕杀的野生大象，但是，还有一部分是来自几乎所有国家都认为是合法的渠道，如自然死亡的大象。因此，当人们在批发市场上尽力限制自己只购买这种合法的象牙时，世界上仅存的少数野生象群是不会受到威胁的。 以下哪项是上述论证所必须假设的 A．试图购买限于合法象牙的批发商能够可靠地区分合法与非法象牙。 B．在不久的将来，对合法象牙产品的需求会持续增长。 C．目前世界上合法象牙的批发来源远少于非法象牙的批发来源。 D．象牙的批发商总是意识不到世界象牙供应减少的原因。 E．持续地供应合法象牙可以得到保证，因为圈养的大象可以繁殖。 |

| 第6题：有确凿证据表明，偏头痛(严重的周期性头痛)不是由于心理上的原因引起的，而完全是由于生理上的原因引起的。然而，研究数据表明，那些因为偏头痛受到专业治疗的人患有标准心理尺度的焦虑症的比率比那些没有经过专业治疗的偏头痛患者高。 下面哪一点如果正确，最有助于解决上述论述中的明显矛盾 A．那些患有偏头痛的人，倾向于有患有偏头痛的亲戚。 B．那些患有偏头痛的人，在心情紧张时经常头痛。 C．那些患有标准心理尺度的焦虑症且发作率较高的人追求专业治疗的可能性要比那些同样尺度上发作率较低的人大。 D．在许多有关偏头痛的起因的研究中，大多数认为偏头痛是由像焦虑这样的心理因素引起的研究已经被广泛宣传。 E．不管他们的医生认为偏头痛的起因是心理方面的，还是生理方面的，大多数患有偏头痛且追求专业治疗的人在他们停止患有偏头痛后仍坚持治疗。 |
