参考答案

参考解析
解析：
细节题。首段第二句提到，自从石油输出国组织在3月份决定减少石油供应以来，原油已从去年12月不到10美元一桶攀升到现在26美元一桶。由此可知，供应量的减少是石油价格攀升的主要原因。故B项正确。首段第四句指出，前两次类似的涨价都导致了通货膨胀和全球经济衰退，A项将因果关系倒置了，故排除。C项文中未提及。第二段第一句指出，伊拉克中止石油出口给这次涨价推波助澜，可见D项并不是主要原因，可排除。

考题 问答题The world economy has run into a brick wall. Despite countless warnings in recent years about the need to address a looming hunger crisis in poor countries and a looming energy crisis worldwide, world leaders failed to think ahead. The result is a global food crisis. Wheat, corn and rice prices have more than doubled in the past two years, and oil prices have more than tripled since the start of 2004. These food-price increases combined with soaring energy costs will slow if not stop economic growth in many parts of the world and will even undermine political stability, as evidenced by the protest riots that have erupted in places like Haiti, Bangladesh and Burkina Faso. Practical solutions to these growing woes do exist, but we'll have to start thinking ahead and acting globally.　　The crisis has its roots in four interlinked trends. The first is the chronically slow productivity of farmers in the poorest countries, caused by their inability to pay for seeds, fertilizers and irrigation. The second is the misguided policy in the U.S. and Europe of subsidizing diversion of food crops to produce biofuels like corn-based ethanol. The third is climate change: take the recent droughts in Australia and Europe, which cut the global production of grain in 2005 and 2006. The fourth is the growing global demand for food and feed grains brought on by swelling populations and incomes. In short, rising demand has hit a limited supply, with the poor taking the hardest blow.　　So, what should be done? Here are three steps to ease the current Crisis and avert the potential for a globa1 disaster. The first is to scale-up the dramatic success of Malawi, a famine-prone country in southern Africa, which three years ago established a special fund to help its farmers get fertilizer and high-yield seeds. Malawi’s harvest doubled after just one year. An international fund based on the Malawi model would cost a mere $10 per person annually in the rich world, or $10 billion in all. Such a fund could fight hunger as effectively as the Global Fund to fight AIDS, TB and Malaria is controlling those diseases.　　Second, the U.S. and Europe should abandon their policies to subsidizing the conversion of food into biofules. The U.S. government gives farmers a taxpayer-financed subsidy of 51 cents per gal of ethanol divert corn from the food and feed-grain supply. There maybe a case for biofuels produced on lands that do not produce foods—tree crops (like palm oil) , grasses and wood products—but there’s no case for doling out subsidies to put the world’s dinner into the gas tank. Third, we urgently need to weatherproof the world’s crops as soon and as effectively as possible. For a poor farmer, sometimes something as simple as a farm pond—which collects rainwater to be used for emergency irrigation in a dry spell—can make the difference between a bountiful crop and a famine. The world has already committed to establishing a Climate Adaptation Fund to help poor regions climate-proof vital economic activities such as food production and health care but has not yet acted upon the promise.
