【正文】 on tons. The World Bank estimates that the largest amount of trash today, about 44 percent, is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic. Now, that may be changing. A new environmentallyfriendly shopping model was recently launched at the World Economic Forum in Davos, Switzerland. This shopping model, called Loop, aims to replace throwaway containers with reusable ones. Loop is the idea of Terra Cycle, an Americanbased recycling pany. Its chief, Tom Szaky told the Associated Press (AP) that removing plastics from the ocean is not enough. He said the point is to get away from singleuse packages. Szaky said that Loop is the future of shopping. But it es from an idea of the past. He pared it to the milkman model of the 1950s in the United States. Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste. Jennifer Morgan from the environmental nonprofit organization Greenpeace also joined in the discussion about Loop at Davos. She said that Greenpeace weles the aim of the Loop Alliance to move away from throwaway culture and disposability. But Morgan questioned whether panies worldwide are ready to change their business models. Loop is set to launch later this year in three eastern . states, and also in Paris, France and some of the surrounding area. Then Loop plans to expand to the . West Coast, Toronto, Canada and Britain by the end of this year or 2020.（1）What does the author intend to do in Paragraph 2?

By the year 2050 that number is expected to rise to 3 billion tons. The World Bank estimates that the largest amount of trash today, about 44 percent, is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic.”可知，世界上的城市每年產(chǎn)生大量的垃圾，并且其中最大的垃圾量是塑料，結(jié)合下文可知，作者寫本段目的是為下文提出新的購物模式提供背景信息。故選A。 （2）考查細(xì)節(jié)理解。根據(jù)第四段中的“Szaky said that Loop is the future of shopping.

Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on his idea that there was an evolutionary basis for older people39。s increased positive outlook. Our research took us in the fascinating direction of exploring how the body uses its energy. When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陳代謝) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energydemanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us hea
