The world economy has run into a brick wall. Despite countless warnings in recent years about the need to address a potential hunger crisis in poor countries and an 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 increased more than three times since the start of 2004. These food-price increases, combined with increasing energy costs, will slow if not stop economic growth in many parts of the world and will even affect political stability. Practical solutions to these problems do exist, but we'll have to start thinking ahead and acting globally.

Here are three steps to ease the current food crisis and avoid the potential for a global crisis. The first is to promote the dramatic success of Malawi, a country in southern Africa, which three years ago established a special fund to help its farmers get fertilizer and seeds with high productivity. 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 altogether

Second, the U.S. and Europe should abandon their policies of paying partly for the change of food into biofuels. The U.S. government gives farmers a taxpayer-financed payment of 51 cents per gallon of ethanol(乙醇) changed from corn. There may be a case for biofuels produced on lands that do not produce foods ---- tree crops, grasses and wood products ---- but there's no case for the government to pay to put the world's dinner into the gas tank.

Third, we urgently need to weather-proof die 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 in dry weather ---- can make the difference between a good harvest and a bad one. The world has already committed to establishing a Climate Adaptation Find to help poor regions climate-proof vital economic activities such as food production and health care but has not yet acted upon the promise.

Mr. Glen is a millionaire. Five years ago, after returning from abroad to his motherland, he   37    up his small company. Speaking of success, Glen often tells us a story about his    38    expensive “school” fees. He always    39    his success to it.

   52    carrying fake and shoddy (偽劣) goods, he would be   53    according to law! Suddenly, his face turned red, and he had nothing in mind after boarding the plane for long.

After returning to the homeland, he often told the story to his family, and his employees, too. He said that this made a deep    54    on him, because an additional high “school” fee that he had ever paid made him realize the value of    55   , which he would    56    as the secret of his success forever.
