问题    Our marine life now is being 【C1】______ by a gathering minefield of plastic in our oceans, and the images in the following make for 【C2】______ viewing. A rainbow runner fish with a(n) 【C3】______kaleidoscope of plastic bits in its liver. A mahi mahi fish with plastic bottle caps in its stomach. Or the mussels and clams, the filters of the sea, that harbour hidden microplastics, 【C4】______ to our naked eye.
   Our first reaction to the above scene is often disgust.【C5】______this reflex quickly【C6】______to a more sobering thought: the【C7】______impact of the eight million metric tons of plastic pollution that enter our ocean every year. Not just【C8】______of our mounting ecological misdeeds, this【C9】______also directly【C10】______to poison us where we are truly vulnerable: our plates.
   The【C11】______of such a future impact how we shop for food. Last year, a European shopper survey【C12】______by the research firm McKinsey & Company,【C13】______a long-known trend: quality food continues to be more important than price. In other words, shoppers【C14】______care about consuming safe food, and willingly【C15】______it with their wallets.
   That is all about to【C16】______. New technology is now【C17】______this information gap and【C18】______the power of knowledge to consumers. By cataloging the long trail of supply chain data on encrypted ledgers, the【C19】______world of the global food network will be exposed. Shoppers will soon be able to follow the "story of the fish"—a report card【C20】______the product’s original photo, place of catch, initial weight, species type, vessel and crew details, RFID tag number, catch water details and more.
【C4】
选项 A、apparent
B、likely
C、invisible
D、accessible
答案C
解析 本句意为“或者像贻贝和蛤蜊这些‘海洋过滤器生物’，身体里都是我们肉眼______的塑料微粒”。根据本句关键词hidden microplastics“隐藏的塑料微粒”可知，our naked eye“我们的肉眼”是难以发现它们的，因此C项“隐藏的，看不见的”为正确答案。A项“明显的”、B项“可能的”和D项“可接近的”均不符合题意。故本题选C。
