Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world’s oceans today, waiting to be eaten by some fish or oyster, and finally perhaps by one of us.Because plastic wasn’t inven ted until the late 19th century, and its production only really took off around 1950, we have a mere 9.2 billion tons of the stuff to deal with. Of that, more than 6.9 billion tons have become waste. And of that waste, a surprising 6. 3 billion tons never made it to a recycling bin—the 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 earth’s last sink. In 2015, Jenna Jambeck, a University of Georgia engineering professor, caught everyone’s attention with a rough estimate: between 5. 3 million and 14 million tons of plastic waste each year just come 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 one-fifth of an inch across.“This isn’t a problem where we don’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 garbag e. “We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle.” It’s a matter of building the necessary institutions and systems, he says, ideally before the ocean turns into a thin soup of plastic.28. 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.29. What’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.30. What does Ted Siegler want to tell us in the last paragraph?A. Some people don’t know the solution of plastics waste.B. Plastics will turn the ocean into a soup of plastic.C. It’s time to take measures to deal with plastic waste.D. People should avoid using plastics to protect the ocean.31. From which is the text probably taken?A. A biology textbook.B. A travel brochure.C. An environmental report.D. A lifestyle magazine.DChoosing to forget something might take more mental effort than trying to remember it, researchers at The University of Texas discovered. Their findings suggest that in order to forget anunwanted experience, more attention should be focused on it.“Decades of research has shown that we have the ability to forget something out of our own free will, but how our brains do that is still being questioned. Once we can figure out how memories are weakened and come up with ways to control this, we can design treatment to help people rid themselves of unwanted memories，” said Jarrod Lewis-Peacock, the study’是senior author.Memories are dynamic constructions of the brain that regularly get updated, adjustedand reorganized through experience. The brain is constantly remembering and forgetting information—and much of this happens automatically during sleep.Their findings not only confirmed that humans have the ability to control what they forget, but that successful intentional forgetting requires more activity than what is required to remember.“A proper level of brain activity is important to this forgetting mechanism. Too strong, it will strengthen the memory; too weak, you won’t change it,” said Tracy Wang, lead author of the study. “Importantly，it’s the intention to forget that increases the activation of the memory, and when this activation hits the proper level sweet spot, that’s when it leads to later forgetting of that experience. ”The researchers also found that participants were more likely to forget scenes than faces. “We’re learning how these mechanisms in our brain respond to different types of information, and it will take a lot of further research before we understand how to use our ability to forget,” said Lewis-Peacock. “Hopefully we can find out how we process and get rid of those really strong memories, which can have a powerful effect on our health and well-being.”32. What remains a puzzle to researchers?A. How our memories can be strengthened.B. How our brains voluntarily forget something.C. What effect unwanted memories have on our brains.D. Whether our brains can voluntarily forget something.33. Which of the following words can best describe memories?A. Casual.B. Stable.C. ActiveD. Permanent.34. It can be learned from the text that .A. it requires less attention to forget than to rememberB. the more active the brain is, the faster it forgetsC. humans can’t keep memories under controlD. humans forget faces less easily than scenes35. What can be a suitable title for the text?A. What It Takes to Forget an Unwanted ExperienceB. Strong Memories Have a Great Influence on HealthC. Forgetting Uses More Brain Power than Remembering .D.
