问题     A third of the planet’s land is severely degraded and fertile soil is being lost at the rate of 24bn tonnes a year, according to a new United Nations-backed study that calls for a shift away from destructively intensive agriculture. The alarming【C1】________, which is forecast to continue as demand for food and productive land increases, will add to the risks of conflicts unless【C2】________actions are implemented, warns the institution behind the report.
    "As the ready supply of healthy and productive land dries up and the population grows, competition is【C3】________for land within countries and globally," said executive secretary of the UN Convention to Combat Desertification (UNCCD) at the launch of the Global Land Outlook. "To【C4】________ the losses, the Outlook suggests it is in all our interests to step back and rethink how we are managing the pressures and the competition. "
    The Global Land Outlook is【C5】________as the most comprehensive study of its type, mapping the interlinked impacts of urbanization, climate change, erosion and forest loss. But the biggest factor is the【C6】________of industrial farming. Heavy tilling, multiple harvests and【C7】________use of agrochemicals have increased yields at the【C8】________of long-term sustainability. In the past 20 years, agricultural production has increased threefold and the amount of irrigated land has doubled, notes a paper in the Outlook by the Joint Research Centre (JRC) of the European commission. Over time, however, this【C9】________fertility and can lead to abandonment of land and【C10】________desertification.

选项

答案 E

解析 分析句子结构可知,空格所在句缺少谓语,因此应填入动词,且根据主语this及本文时态为现在时可知,该谓语动词应该使用第三人称单数形式。上文提到,机械化农业的扩张导致土地失去可持续发展的能力,再结合下文中的土地被撂荒可知,此处说的是随着时间的推移,土地生产力下降了,故E)diminishes“降低,削弱”为本题答案。
