【正文】 her face stretch and relaxand her reactions changeas she continues reading. That39。 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.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 programss 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。Delighted.Unwilling.Confused.Optimistic.（2）What can we infer about previous news robots? A.They looked like a human beingC.They could interact with audience.（3）What do we know about the third technology? A.This technology is quite popular nowC.This technology is far from mature.（4）From the last paragraph, we can draw a conclusion that____. A.Al anchors perform much better than human news anchors at presentC.t replace human news anchors in the near futureD. （1）考查詞義猜測。s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday及第二段中的That39。 （2）考查推理判斷。 she reads it almost like a human being.

They need to do more to prepare for the sideeffects. Countries are removing cash at varying speeds. In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years. America is perhaps a decade behind. Outside the rich world, cash is still king. But even there its leading role is being challenged. In China digital payments rose from 4% of all payments in 2012 to 34% in 2017. In the main, the prospect of a cashless economy is excellent news. Cash is inefficient. When payments dematerialise, people and shops are less open to theft. It also creates a credit history, helping consumers borrow.s shopping habits and private multinationals exploit their personal data.（1）Some rich countries are trying to dematerialize moneyB.make the economy more efficient by protecting endangered speciesD.the differences between developed and developing countriesB.digital payments are being a trend that cannot be stoppedD..

Some ants will just cheat and take the nectar and run, but some will stick around and attack anything that tries to hurt the plant.
