The effects of the exercise were clear. The people were better at remembering images after they had ridden the bike, especially when the images most closely resembled one another. In other words, the harder their memories had to do their best, the better they performed after the exercise. The M. R. I. scans showed that memory parts of each people39。 The scientists invited 36 people of different ages to the lab and had them sit quietly on a fixed bicycle for 10 minutes or, on a separate visit, pedal the bicycle at a pace so gentle that it barely raised their heart rates. It also was short, lasting for only 10 minutes. Immediately after each session of the sitting or slow pedaling, the people pleted a puterized memory test during which they would see a brief picture of, for instance, a tree, followed by a variety of other images and then a new image of either the same tree or a similar one. The people would press buttons to show whether they thought each image was new or the same as an earlier shot. The test is difficult, since many of the images closely resemble one another. It requires rapid, skillful scanning recent memories to decide whether a picture is new or known. Next, the scientists had each people repeat this processriding or sitting on the bike for 10 minutes and then pleting memory testingbut the testing now took place inside an M. R. I. machine(磁共振成像儀)that scanned the people39。2．閱讀理解 故選B。 （4）主旨大意題。根據(jù)But Andersen says there is more that people can do.

There are efforts around the world to address the problem, including at this newly opened recycling center in Lebanon(黎巴嫩). But Andersen says there is more that people can do. “Cut back on singleuse plastics, straws, plastic cups, plastic water bottles, plastic bags and find alternatives like reusable materials.” She says healthy oceans are essential to our survival.（1）What can we learn from the passage? A. The pieces of the plastic garbage infect the food chain, sometimes visibly, and more so at the microscopic level, where the plastic particles interact with other pollutants. “There are heavy metals, medicines, industrial waste in the sea, while it acts like magnets(磁鐵). These poisonous substances absorb on the plastic, and then when seafood absorbs the plastics, those poisonous substances enter the fatty tissues. ”To be consumed by other sea life and by people at last.s oceans. A film crew traveled the globe to document the rubbish. And Julie Andersen of the Plastic Oceans Foundation says what we see is just the tip of the problem. “Half of the waste actually sinks to the bottom, and that remains on the surface actually breaks down. ”（英語(yǔ)）高考英語(yǔ)高中英語(yǔ)閱讀理解解題技巧及練習(xí)題一、高中英語(yǔ)閱讀理解1．閱讀理解 Plastic sludge(污泥)and garbage is a disaster for the world39。 The filmmakers found rubbish in ocean gyres, the circulating currents that trap large concentrations of pollution in the Atlantic, Indian, and Pacifc Oceans, home of what some have plastic. What we found was a plastic smog that spread throughout all the water. And in some parts of the oceans, scientists have found more plastic than plant. ” China, Indonesia, the Philippines, Thailand and Vietnam are the worst plastic polluters.
