生态系统(ecosystems),有利生态(eco-friendly),河流群落(river community)等等表达,都是与生态环境相关的表达。
老夏考研“每日一题”选自《自然》,原文文章标题为“Prepare river ecosystems for an uncertain future”(为不确定的未来做好河流生态系统的准备)。
今天这个词“resilience”是一个外刊高频词,虽然不在大纲词表内,但还是值得关注哟。
【题目】The word “resilience” is closest in meaning to ______
[A] diversity.
[B]mechanism.
[C] reluctance.
[D] flexibility.
【试题】
①To maintain water supplies and avoid devastating fish population crashes, rivers must be managed adaptively, enhancing their resilience* and limiting risk. ②Researchers must also develop better forecasting tools that can project how key species, life stages and ecosystems might respond to environmental changes. ③This will mean moving beyond simply monitoring the state of ecosystems to modelling the biological mechanisms that support their survival. ④Today, river managers track properties such as species diversity and population abundance, and compare them with historical averages. ⑤If they spot troubling declines, they might intervene by, for instance, altering the amount of water released from dams. ⑥But by the time trends are detected, they can be impossible to check. ⑦Understanding how sensitive ecosystems might change is crucial to managing them in the future.
【参考译文】
①To maintain water supplies and avoid devastating fish population crashes, rivers must be managed adaptively, enhancing their resilience and limiting risk. 为了维持水的供应和避免毁灭性的鱼类数量崩溃,必须对河流进行适应性管理,增强其顺应力并限制风险。
②Researchers must also develop better forecasting tools that can project how key species, life stages and ecosystems might respond to environmental changes. 研究人员还必须开发更好的预测工具,以预测关键物种、生命阶段和生态系统可能如何对环境变化作出反应。
③This will mean moving beyond simply monitoring the state of ecosystems to modelling the biological mechanisms that underpin their survival. 这将意味着不仅仅是监测生态系统的状态,还要模拟支撑它们生存的生物机制。
④Today, river managers track properties such as species diversity and population abundance, and compare them with historical averages.如今,河流管理人员会追踪物种多样性和种群丰度等属性,并将它们与历史平均水平进行比较。
⑤If they spot troubling declines, they might intervene by, for instance, altering the amount of water released from dams. 如果他们发现了令人不安的水量下降,可能会进行干预,例如水坝放水改变大坝的水量。
⑥But by the time trends are detected, they can be impossible to check.但是当趋势被探查到的时候,水量下降也不无法遏制了。
⑦Understanding how sensitive ecosystems might change is crucial to managing them in the future.了解敏感的生态系统可能会发生怎样的变化,对于未来管理它们至关重要。
