【答案解析】[听力原文]14-16
The energy crisis has been with us for a long time and will be with us for an even longer period. Because the supply of oil can be shut off unexpectedly at any time, and what's more, the oil wells will run dry in thirty years or so at the present rate of use. TO make the situation worse, there is as yet no sign that any slo wing of the world's population is in sight. Although the birth rate had dropped in some nations, including the United States, the population of the world seems sure to pass six billion as the twenty-first century opens. With such a large population, there will be more problems we have to deal with in the future. Food is one of them.
To begin with, the world's food supply is going to become steadily tighter. The world will find it hard to expand production to fill the additional mouths. Scientists are striving to create artificial food. A big progress has been made and soon people may have to accept more "unnatural food". That might be a way to solve the food problem.
