问题     The price of wheat is setting an all-time high in the United Kingdom. Food【C1】______are spreading across Algeria. Russia is【C2】______grain to sustain its cattle herds【C3】______spring grazing begins. And the U. N. Food and Agricultural organization announced that its food price index for December【C4】______an all-time high.
    But【C5】______in years past it’s been weather that has caused a spike in commodities prices, now it’s trends on both sides of the food supply /demand equation that are【C6】______up prices. On the demand side, those to blame are population growth, rising【C7】______, and the use of grain in car fuel. On the supply side: soil【C8】______, the loss of cropland to non-farm uses, and—on【C9】______of climate change—crop-withering (农作物枯萎) heat waves and【C10】______mountain glaciers and ice sheets. These climate-related trends seem destined to take a far greater【C11】______in the future. The current【C12】______in world grain and soybean (大豆) prices, and in food prices more broadly, is not a【C13】______phenomenon. We can no longer expect that things will soon return to normal, because in a world with a【C14】______changing climate system there is no【C15】______to return to.
    The unrest today is no longer【C16】______between heavily armed superpowers, but【C17】______spreading food shortages and rising food prices that【C18】______our global future. Unless governments quickly redefine security and shift【C19】______from military uses to investing in climate change ease, water efficiency, soil【C20】______, and population stabilization, the world will in all likelihood be facing a future with both more climate instability and food price volatility (波动).
【C20】
选项 A、erosion
B、safeguard
C、reduction
D、conservation
答案D
解析 名词辨义题。根据前面提到的“加大在缓和气候变化、提高用水效能等方面的投入”可知，此处也指采取的积极行为，soil conservation“土壤保持”符合题意。erosion“腐蚀”；safeguard“保护措施”，语气强，指采取积极措施预防可能发生的一切攻击或危险；reduction“减少”，均与题意不符，故排除。
