At first sight, you would think the collection of hundreds of colored shards（碎片）could be a work of abstract art. But the objects are the contents of the stomach of a sea turtle that lost its battle with plastic pollution.
Environmentalists examined the stomach of the turtle found off the coast of Argentina. What they found is the symptom of the increasing threat to sea turtles from a human addiction to plastic.
Sea turtles often mistake plastic items for jellyfish or other food. Ingesting（摄取）ocean pollution can cause a digestive blockage and internal cuts. The result can be dangerous, followed by death.
Humans produce 260 million tons of plastic a year. When those products are pulled into the sea’s currents, the plastics are just broken into smaller pieces which are consumed by marine life at the bottom of the food chain. An examination of a green turtle found off Florida discovered that, over the course of a month, the animal’s faeces（粪便）had contained 74 foreign objects, including “four types of balloons, different types of hard plastic, a piece of carpet--like material and two 2--4 mm tar balls.”
“The oceans have become a giant refuse bin for all manner of plastics. All sea turtle species may be seriously harmed, “according to the biologists Colette Wabnitz, from the University of British Columbia. ”The symptom of this growing crisis can be seen inside and on sea turtles as well as their oceanic and terrestrial habitats. It is urgently necessary to directly confront the source of plastic pollution, redesign packaging and rethink the very idea of ‘throwaway culture’.”
Almost all marine species, from plankton to whales, have ingested plastic. But, even in small quantities, plastic can kill sea turtles, the biologists said.
Fifty out of 92 turtles found dead, stranded on the shorelines of Rio Grande do Sul state in Brazil, had ingested a “considerable amount of man-made debris”.
【小题1】What’s tile passage mainly about?A．How to prevent the sea turtle from plastic.B．Why plastic is dangerous to the sea turtle.C．Protecting the sea turtle from being polluted.D．Sea turtles suffering from plastic pollution.【小题2】The author mentions the “throwaway culture” probably in a（n） tone.A．praisingB．positiveC．ironicD．comedic【小题3】The underlined word in the last paragraph probably means .A．a kind of foodB．a kind of fishC．pieces of clothD．pieces of rubbish【小题4】The paragraph following the last one will probably talk about .A．the way the biologists examined the sea turtleB．some tips on how to make sea turtles avoid plasticC．how to prevent plastic pollutionD．the reason why we should protect the sea turtleD

(答案→)D 解析：试题分析: 目前人类产生的垃圾越来越多，大量垃圾进入海里后，塑料等物品不会腐烂，只是会分解成小块的物品而被海洋生物误食，因而造成了海龟的大量死亡。在本文中作者就这个问题用讥讽的语言介绍了这种现象。【小题1】D。主旨大意题。文章开头描述了海龟胃里面五颜六色的东西，指出这是海龟误食的塑料垃圾等，然后在下文详细介绍了垃圾对海龟造成的危害，由此判断文章中心内容是关于塑料垃圾对海龟的危害，故答案选D。【小题2】C。推理判断题。A赞扬的；B积极的；C讽刺的，反语的；D喜剧的。从文章倒数第三段. It is urgently necessary to directly confront the source of plastic pollution, redesign packaging and rethink the very idea of ‘throwaway culture’.”可以推断作者对“throwaway culture”是持反对态度的，由此推断作者是用讽刺的语气，答案选C。【小题3】D。词义猜测题。整篇文章介绍了海龟因误食垃圾而大量死亡的情况，再根据…..had ingested a “considerable amount of man-made…. 推断划线的词应该指一种垃圾，故答案选D。【小题4】C。推理判断题。文章开头提出了海龟因误食垃圾而死亡的问题，然后再对此进行分析，根据提出问题，分析问题，解决问题的写作模式可以判断作者接下来要讨论的是如何去保护海龟，避免垃圾污染的问题， 故答案选C。

就是这个解释
