[解析]
(1)D.推理判断题。根据文章第一段Due to climate change and changes in land use,wildfires are predicted to rise by up to 14 percent by 2030,30 percent by 2050 and 50 percent by the end of this century,and even areas once considered safe from major fires such as the Arctic,will "very likely" experience a major increase in burning,according to a new report by the UN Environment Programme (UNEP). (根据联合国环境规划署的一份新报告,由于气候变化和土地利用的变化,森林野火预计到2030年将上升14%,到2050年30%,到这个世纪末达到50%,即使是像北极这样曾经被认为安全的地区也很有可能经历燃烧大幅度增加)可知联合国环境规划署的报告预计森林野火是在逐渐上升的,所以作者提到北极是为了表明野火逐渐上升的趋势。故选D项。
(2)C.段落大意题。根据文章第三段Wildfires can threaten people's health and lives,contaminate water,destroy crops and reduce land available to grow food.Costs of rebuilding after areas are struck by wildfires can be beyond the means of low﹣income countries.Wildlife,as well as natural habitats,is also rarely spared.(野火会危及人们的健康和生命,污染水,破坏农作物,减少可耕种的土地。在野火袭击后重建地区的成本可能超出了低收入国家的能力。野生动物和自然栖息地也很少能幸免)可知文章第三段主要是围绕着野火所带来的可能的危害展开。故选C项。
(3)B.推理判断题。根据文章第四段The publication calls on governments to adopt a new "Fire Ready Formula," with two﹣thirds of spending devoted to planning,prevention,preparedness,and recovery,with one﹣third left for response. (该刊物呼吁各国政府采用一种新的应急公式,将三分之二的开展用于计划、预防、准备和恢复,剩下的三分之一用于应对)以及We have to minimize the risk of extreme wildfires by being better prepared:invest more in fire risk reduction and shift from passive response to prevention and preparedness, (我们必须通过更好的准备,将极端野火的风险降到最低;在降低风险上增加投资,并从被动反应转向预防和准备)可知环境署的报告呼吁我们要将投资投在预防和准备方面,B项中的 "Restoring wetlands as well as wildlife species.(恢复湿地和野生动物)"属于预防方面的投资。故选B项。
(4)A.细节理解题。根据文章第二段The report,Spreading like Wildfire:The Rising Threat of Extraordinary Landscape Fires,says that wildfires and climate change are "mutually exacerbating." Wildfires are made more serious by climate change through increased drought,high air temperatures,low humidity,lightning,and strong winds.Meanwhile,climate change is made worse by wildfires,mostly by ravaging sensitive and carbon﹣rich ecosystems like rainforests.(这份名为《野火般蔓延:异常景观火灾的威胁不断上升》的报告称,野火和气候变化正在相互加剧。由于气候变化,干旱加剧,气温升高,湿度降低,闪电和强风野火变得更加严重。与此同时,野火使气候变得更糟,主要是由于破坏了热带雨林等敏感而富含碳的生态系统)可知野火和气候变化正在相互加剧。故选A项。
