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. 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.Provide background information.Explain the reason for trash.D.United States and Switzerland.B.France and Canada.（4）What is the text mainly about? A.The development of future city.C. （1）考查推理判斷。 （2）考查細(xì)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(jì)劃在2020年前將業(yè)務(wù)擴(kuò)大到加拿大和法國。故選A。 Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has bee an annual publichealth emergency despite government vows to solve the problem. 根據(jù)第三段“Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has bee an annual publichealth emergency despite government vows to solve the problem.”印度首都的空氣污染飆升至多年來最嚴(yán)重的水平，籠罩著這座城市的濃霧已成為年度公共衛(wèi)生緊急事件，盡管政府誓言要解決這個(gè)問題；第五段“New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coalbased power plants, swirling dust ..., leaving Delhi the world39。由此可判斷出政府幾乎沒有保護(hù)其公民免受嚴(yán)重污染。學(xué)校、大學(xué)、醫(yī)院和市場(chǎng)分發(fā)了數(shù)百萬個(gè)防污染口罩。根據(jù)第五段中的“New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coalbased power plants, swirling dust from construction sites and roads and smoke from crop stubble burning in neighboring states.”本句是說新德里每年都籠罩在污染中。故選A。故選B。m using at the time? There39。Is it necessary to learn more than one foreign language?C.care less about the five peoplepull the switch to the side tracksC.sacrifice the stranger on the footbridge（3）The underlined word in Paragraph 5 is closest in meaning to . A.C. （1）考查細(xì)節(jié)理解。根據(jù)第四段中的“But Costa and his colleagues found that presenting the dilemma in a language that volunteers had learned as a foreign tongue dramatically increased their stated willingness to push the sacrificial person off the footbridge, from fewer than 20% of respondents working in their native language to about 50% of those using the foreign one.”可知，志愿者們用已經(jīng)學(xué)會(huì)的外語來表達(dá)這種兩難境地時(shí)，極大地增加了他們將犧牲者推下人行橋的意愿。根據(jù)第五段中的“According to one explanation, such judgments involve two separate and peting ways of thinking173。 （4）考查細(xì)節(jié)理解。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和詞義猜測(cè)兩個(gè)題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，從而選出正確答案。 For some time, psychologists have been studying how personality traits affect health and healthrelated choices. Not surprisingly, they have found that people blessed with innate conscientiousness, meaning that they are organized and predictable, typically eat better and live longer than people who are disorderly. They also tend to have immaculate offices.t necessarily innately conscientious. To find out, researchers at the University of Minnesota conducted a series of experiments. In the first experiment, they randomly assigned a group of collegeage students to spend time in two office spaces, one of which was very neat, the other wildly cluttered (亂堆) with papers and other workrelated stuff. The students spent their time filling out questionnaires unrelated to the study. After 10 minutes, they were told they could leave with an apple or a chocolate bar. Those students who sat in the orderly office were twice as likely to choose the apple as those who sat among the mess.B.terrible1
