This makes tracking and monitoring the problematic rubbish using technology like satellites challenging for researchers.”可知,污染地球海洋的大部分塑料在海浪之下,这使得使用卫星等技术跟踪和监测有问题的垃圾具有挑战性,由此可知,研究人员在海洋污染方面面临隐藏的塑料的挑战。故选A项。 2.B 段落大意题。根据第二段“As detailed in a study published on June 14 in Nature Communications, a project trained a machine-learning program on 300,000 images of the Mediterranean Sea gathered over six years by the European Space Agency’s Copernicus Sentinel-2 satellite. The team then used this database to identify what are known as windrows—floating filaments (丝状物) composed of garbage and plastic formed by ocean currents and wind.”可知,本段主要介绍的是确认风积丘(windrows)的过程。故选B项。 3.A 词义猜测题。根据画线单词所在的句子“While windrows only account for an extremely small portion of overall ocean litter, researchers theorized the rubbish could serve as proxies for pollution hot spots.”可知,风积丘占海洋垃圾的很小部分,结合下文中的“Between July 2015 and September 2021, the team detected and monitored a total of 14, 374 windrows—an exponential (越来越快的) increase in documented litter structures.”可知,该团队共检测并监测了14 374个风积丘———记录的垃圾结构增长速度越来越快,由此可推断,这些风积丘可以看作是垃圾的标志,所以画线单词的意思与“标志”意义相近。故选A项。 4.C 推理判断题。根据倒数第二段中的“Further analyses allowed the team to infer a number of influences, such as nearby population distribution, geograph ... ...
