Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world39。s oceans today, waiting to be eaten by some fish or oyster, and finally perhaps by one of us. Because plastic wasn39。t invented until the late 19th century, and its production only really took off around 1950, we have a mere billion tons of the stuff to deal with. Of that, more than billion tons have bee waste. And of that waste, a surprising billion tons never made it to a recycling binthe figure that shocked the scientists who published the numbers in 2017. No one knows how much unrecycled plastic waste ends up in the ocean, the earth39。s last sink. In 2015, Jenna Jam beck a University of Georgia engineering professor, caught everyone39。s attention with a rough estimate between million and 14 million tons of plastic waste each year just e from coastal regions. Meanwhile, ocean plastic is estimated to kill millions of marine(海洋的）animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly, stuck by abandoned things made of plastic. Many more are probably harmed invisibly. Marine species of all sizes, from zooplankton to whales, now eat microplastics, the bits smaller than onefifth of an inch across. This isn39。t a problem where we don39。t know what the solution is, says Ted Siegler, a Vermont resource economist who has spent more than 25 years working with developing nations on garbage. We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle. It39。s a matter of building the necessary institutions and systems, he says, ideally before the ocean turns into a thin soup of plastic. （1）Why does the author mention the Pilgrims in paragraph 1? A.To prove plastic was difficult to invent.B.To introduce what marine animals like eating.C.To tell the Pilgrims contributed a lot to the marine protection.D.To show plastic waste has a lasting effect on the ocean.（2）What39。s the main trouble marine animals face according to the text? A.Lacking protection.B.Being stuck by plastics.C.Being caught by humans.D.Treating plastics as food.（3）What does Ted Siegler want to tell us in the last paragraph? A.Some people don39。t know the solution of plastics waste.B.Plastics will turn the ocean into a soup of plastic.C.It39。s time to take measures to deal with plastic waste.D.People should avoid using plastics to protect the ocean.（4）From which is the text probably taken? A.A biology textbook.B.A travel brochure.C.An environmental report.D.A lifestyle magazine.【答案】 （1）D（2）B（3）C（4）C 【解析】【分析】本文是一篇說(shuō)明文，介紹了塑料垃圾給海洋以及海洋生物帶來(lái)的危害。 （1）考查推理判斷。根據(jù)第一段中的“their plastic waste would likely still be around four centuries later.”他們的塑料廢物很可能在四百年后仍會(huì)存在，可知 作者提到the Pilgrims是為了說(shuō)明塑料廢物對(duì)海洋有持久的影響，故選D。 （2）考查細(xì)節(jié)理解。根據(jù)第四段中的“Some are harmed visibly, stuck by abandoned things made of plastic. Many more are probably harmed invisibly.”一些明顯受到傷害，被塑料制成的廢棄物品卡住了?？赡苡懈嗟娜耸艿綗o(wú)形的傷害?？芍xB。 （3）考查推理判斷。根據(jù)最后一段中的“It39。s a matter of building the necessary institutions and systems, he says, ideally before the ocean turns into a thin soup of plastic.”他說(shuō)最好在海洋變成塑料湯之前建立一個(gè)必要的機(jī)構(gòu)和制度的問(wèn)題，可推知選C。 （4）考查推理判斷?？v觀全文可知，本題介紹了塑料垃圾給海洋以及海洋生物帶來(lái)的危害。是一篇環(huán)境保護(hù)類(lèi)閱讀，因此選C。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇環(huán)保類(lèi)閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。5．犇犇閱讀理解 Acting is the least mysterious of all crafts, Marion Brando once said. But for scientists, working out what is going on in an actor39。s head has always been something of a puzzle. No
