Larsen C is a long way south and there39。To explore a new way to prevent climate change.D.It will disappear in a very short time.D.根據(jù)第二段中的“Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light.”可知，科學(xué)家著急趕去世界最大的冰山是為了在其受到光照影響之前研究這座冰山下面的海洋生態(tài)系統(tǒng)。根據(jù)最后一段中的“…At the current rate, the world39。t always change according to the content.

But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools, the team said, noting its design can inspect bags or luggage without being an exposure to privacy. signals.D.B. （2）考查細(xì)節(jié)理解。根據(jù)最后一段中的“Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes”今后的工作將繼續(xù)側(cè)重于提高識別物體和成像形狀及體積的準(zhǔn)確性，故選B。 Having conducted previous research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the way in which food was served also had a psychological effect. They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of petition. However, they also reasoned that it could instead lead people to bee more aware of others39。B.To find out whether sharing food can get people close emotionally.（3）Why were participants asked to eat up the snack before the game?

Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain.可知，蝙蝠飛行的另一個有趣特征是蝙蝠倒立著降落的方式！不同于那些降落在地上或樹枝上的鳥，觀察到蝙蝠可以四處飛行，然后突然倒掛在頭頂?shù)奈矬w上。 Environmental experts warn that our planet is drowning in 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.Explain the reason for trash.United States and Switzerland.B.The development of future city.C. （1）考查推理判斷。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(wù)擴大到加拿大和法國。 （4）考查主旨大意。s cities produce 2 billion tons of trash every year. 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。s environmental issue.Canada and Britain.Demand of some panies.C. 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.因此蝙蝠與鳥不同，蝙蝠可以倒掛著。根據(jù)第二段中的 In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings…This makes coordinating (協(xié)調(diào)) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances.可推斷出，過去人們認(rèn)為蝙蝠與鳥在飛行運動方式與鳥沒有區(qū)別，最近的研究發(fā)現(xiàn)，這是不正確的，故也是要糾正的，故選C。以前人們認(rèn)為蝙蝠和鳥類在運動方面沒有什么區(qū)別，但現(xiàn)在的研究證明蝙蝠的構(gòu)造不同于鳥類，它們的翅膀由前肢和后肢組成，它們自我調(diào)節(jié)能力好，可迅速改變飛行方向，或完全逆行，這是鳥類不容易做到的，而且蝙蝠飛行的另一個有趣特征是蝙蝠倒立著降落的！這不同于那些降落在地上或樹枝上的鳥。the sense of flying heightC.B.
