中小学教育资源及组卷应用平台 Unit 3　Times change！ 【话题导入】 Robots have certain advantages compared to① humans. They are efficient②， tireless, can be repaired when damaged and they never get sick. The last quality has made them the star during our fight against the COVID 19(新冠肺炎). [1]While thousands of medical workers have fallen ill③ dealing with this highly infectious④ virus and a lot more have to stay at home for fear of⑤ getting the disease, this isn't a problem for robots. This is why the COVID 19 outbreak is seen as the “tipping point” for robots to start to replace humans in certain jobs.,In hospitals, robots are used to perform high risk tasks. In China, for example, a hotel in Hangzhou employed a robot to deliver⑥ food to people under quarantine (隔离). In Spain, robots are about to be used to test people for the coronavirus (冠状病毒).,In non medical companies, robots are also replacing human employees since they don't have the problem of the social distancing and will never take sick leave⑦. Fast food chains like McDonald's are not only delivering food with robots in some areas, but also looking to use them as cooks and servers. Walmart and Amazon, for example, where robots are already used in packing and shipping, are planning to increase the number of robots in these areas. But this sudden boom⑧ in robot demand doesn't mean that they can replace humans successfully in every aspect⑨. According to Bill Smart, a roboticist at Oregon State University, the human contact between doctors and patients is still important. Doctors comfort the patients and guide them through hard decisions while robots are only doing daily tasks, like cleaning and giving tests. [2]It might be true that robots have certain advantages over⑩ humans, but they are still secondary to human's communication and emotion.
