本篇文章主要讲的是海洋上有大量的的塑料垃圾。很大一部分都来自于捕鱼的网上的碎片。这些垃圾环绕着整个世界的水。减少我们自己的垃圾才能为减少海洋垃圾做贡献。下面前程百利小编带大家一块看一下这篇托福听力背景材料中出现的生词，希望能给正在备考托福听力的同学带来帮助。
The Great Pacific Garbage Patch may be the most infamous (名声狼藉的)of the world's floating trash(垃圾) dumps(倾倒). But it's far from the only one. There's plastic trash littering(垃圾) "the Bay of Bengal, the Mediterranean Sea, the coast of Indonesia, all five subtropical gyres; coastal regions(沿海地区), enclosed (与世隔绝)bays, seas and gulfs(海湾)." Marcus Eriksen, director of research at the Five Gyres Institute.
Eriksen surveyed those areas, along with his seafaring(航海的) colleagues. Collectively,(共同的) they spent some 900 hours logging(记录) every large piece of plastic they could spot from their boats. And they trawled(拖网) for plastic nearly 700 times along the way, picking through their nets and cataloguing(目录) the debris(碎片). "I find the necks of bottles, fragments of toothbrushes(牙刷) and combs. Action figure parts. Army men. I find a lot of army men."
The researchers plugged (阻塞)that trash census(普查数据) data into ocean models, which simulate the circulation(流通) of the world's waters. Based on the densities(密度) of trash the researchers found, the models predicted some 5.25 trillion particles(微粒) of plastic may be floating out there…adding up to about 269,000 tons. And more than 90 percent of those pieces may be smaller than a grain of rice. The study appears in the journal PLOS ONE.
What happens to all that plastic? "The ocean's going to take it, blast it to smithereens(碎片), it's going to cycle it through marine organisms, and sink it to the sea floor. That's the ultimate (最终的)life cycle, I believe, for plastics. We're like constantly sprinkling(喷洒) fish food on the entire ocean surface." The solution, Marcus says, isn't some fleet(舰队) of seafaring(航海的) garbage trucks(垃圾车). It's keeping our trash to ourselves—which would be a sea change in behavior.
