【正文】 ose emotionally.（3）Why were participants asked to eat up the snack before the game? A.To prove sharing food increases petition.C.A meal taken in a family atmosphere.（2）For what purpose did the researchers carry out the present experiments? A.A meal consumed by oneself.B.A meal taken at home. The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster（in 8. 7rounds）than those who did not（ rounds）. A similar experiment was conducted with 104participants and Goldfish crackers（餅干）, this time negotiating an airline39。 For the first test they recruited 100 pairs of participants from a local cafe, none of whom knew each other. The participants were seated at a table and fed tortilla chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began. 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。5．犇犇閱讀理解 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)側重于提高識別物體和成像形狀及體積的準確性，故選B。檢查行李總是需要人力，我們希望開發(fā)一種互補的方法來減少人力，可推知選A。s in airports.

In large public areas, it39。 When it was tested on a backpack, the accuracy rate topped 95 percent. 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. Research suggested that WiFi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天線)that could be fitted in existing WiFi networks.4．犇犇閱讀理解根據(jù)最后一段中的Actually. AI is still no match for human qualities.可知，人工智能仍無法與人類素質相匹敵，由此可知，在不久的將來，人工智能新聞主播不會取代人類新聞主播，故選C。 t always change according to the content. As a result, her expressions look anything but human.可知，真正的難點在于第三技術，使辛曉萌的面部表情根據(jù)新聞報道的內容而變化，事實上，辛曉萌的表情不總是隨著內容而變化，她的表情一點也不像人類，由此可知，第三技術還遠遠不夠成熟，故選D。 （3）考查推理判斷。根據(jù)第二段中的Unlike previous news robots though, Xin does not read news like a cold machine。s why many news anchors were worried: Will AI replace us in the near future?可知，擔心將來自己的工作會被人工智能取代的新聞主播一定不愿意透露下面這個消息：上周日，新華社新聞主播辛曉萌成為世界上第一位女性人工智能新聞主播，由此可知畫線詞詞義為不愿意的，故選B。根據(jù)第一段中的Xin Xiaomeng began working as the world39。Xin Xiaomeng s expressions vary so naturally that they are true to life【答案】 （1）B（2）A（3）D（4）C 【解析】【分析】本文是一篇說明文，上周日，新華社新聞主播辛曉萌成為世界上第一位女性人工智能新聞主播，作者介紹了人工智能背后的技術，并指出在不久的將來，人工智能新聞主播不會取代人類新聞主播。Al news anchors won39。human news anchors should learn from AT anchors to save their jobsB.This technology remains at the theoretical stageD.This technology is very perfect so farB.They could interview sports starsD.They read news without expressions.B.D.C.B.t always change according to the content.

Both the technologies used to make Xin39。 Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person39。s why many news anchors were worried: Will AI replace us in the near future? Unlike previous news robots though, Xin does not read news like a cold machine。 News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world39。 【點評】本題考點涉及細節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇環(huán)境類閱讀，考生需要準確掌握細節(jié)信息，同時根據(jù)上下文的邏輯關系，進行分析，推理，從而選出正確答案。根據(jù)最后一段中的“…At the current rate, the world39。根據(jù)第一段中的“to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.”到達一個新發(fā)現(xiàn)的在拉森冰架下面隱藏了12萬年的的生態(tài)系統(tǒng)，可知選D。故選C。 （2）考查詞義猜測。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)。冰山下面顯現(xiàn)的新的海洋生態(tài)系統(tǒng)為科學家提供了研究未知的海洋生物的機會。Many creatures living in deep water will die ou
