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）考查細節(jié)理解。根據(jù)第四段中的“Szaky said that Loop is the future of shopping. But it es from an idea of the past.”和第五段“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.”可知，Loop購物模式的想法來自于過去送奶工模式，是一種可以杜絕零浪費的模式。故選C。 （3）考查細節(jié)理解。根據(jù)最后一段“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.”可知，Loop計劃在2020年前將業(yè)務擴大到加拿大和法國。故選D。 （4）考查主旨大意。根據(jù)第三段中的“A new environmentallyfriendly shopping model was recently launched at the World Economic Forum in Davos, Switzerland.”及全文內(nèi)容可知，文章主要介紹美國一家公司推出一種新的零浪費購物模式。故選A。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇環(huán)保類閱讀，考生需要準確掌握細節(jié)信息，并根據(jù)上下文進行邏輯推理，概括歸納，從而選出正確答案。5．犇犇Choose the one that fits best according to the information given in the passage you have just read. 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 healthy in the future. We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function. When you39。re being chased by a tiger, you don39。t need to waste energy making immune cells to fight off tomorrow39。s cold. What you need is to shift all available energy resources to your legs, with the hope that you will live to experience another cough or sneeze. As a result, our immune system evolved to run in maximum amounts when we39。re happy, but to slow down dramatically when we39。re not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, being more focused on the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the unpleasant things in life more easily.（1）According to Robert Trivers, when our body needs extra energy, ______. A.muscles will respond to it by relaxing a little bitB.organs will speed up metabolic processes to answer itC.immune system will temporarily shut down to fulfill itD.brain will satisfy it by sharing optional metabolic output（2）In paragraph 3 this relationship most probably refers to the one between ______.
