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? A. 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. The world39。故選B。 （4）考查推斷判斷。 （3）考查代詞指代。綜上所述，可知，蝙蝠與鳥運動方式的不同是本文的主題。 （1）考查主旨大意。B.Bats might hurt themselves when landing.the flying directionThey sleep upside down.C.Ways in which bats move differently from birds.（2）Which of the following is a false assumption about bats that was recently corrected? A. these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.（1）Which of the following is the topic of the passage? A. 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. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢體). 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. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or pletely reverse it, something a bird cannot easily do.可知選C。 出于好奇心，他們做了一系列實驗。 （2）考查細節(jié)理解。根據(jù)第二段中的“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。D.To reward them for their participation.C.To confirm sharing food can promote cooperation.D.D.s route prices. The results were much the same, with the foodsharers negotiating successfully 63. 3%of the time and those who did not share doing so 42. 9%of the time. （1）What does the familystyle meal in the report refer to？ A. The game asked the participants to negotiate an hourly wage rate during a fictional strike. Each person was randomly assigned to represent the union or management and follow a set of rules. （4）考查詞義猜測。s hard to set up expensive screening equipment like what39?？芍xB。D.Discovering.D. privacy.It uses antennas to pick up networks39。The benefit of the study findings.（2）What39。The principle the study is based on. It uses channel state information (CSI) that is readily available in lowcost WiFi devices. This could have a great impact on protecting the public from dangerous objects, said Yingying Chen, a coauthor of the study, There39。 A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them. These items could include weapons, chemicals, laptops and batteries for bombs, the research team said on Tuesday. 【點評】本題考點涉及詞義猜測和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確掌握細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。根據(jù)最后一段中的The real difficulty lies in the third the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don39。 （2）考查推理判斷。 （1）考查詞義猜測。Al anchors perform much better than human news anchors at presentC.This technology is quite popular nowC.They looked like a human beingC.s performance impressive are mature. The real difficulty lies in the third the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don39。s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro electric motors behind her face move to make her expressions seem more human. she reads it almost like a human being. The muscles on her face stretch and relaxand her reactions changeas she continues reading.
