Directions: Read the following passages. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need. Your Next Nurse Could Be a Robot Dr. De Momi, of the Politecnico di Milano (Italy), led an international team that trained a robot to imitate natural human actions. Over time this should lead to improvements in safety during surgeries because unlike their human counterparts robots do not tire and can complete an endless series of precise movements. The goal is not to remove human skill from the operating room, but to complement it with a robot's particular skills and benefits. "As a roboticist, I am convinced that robotic (co)workers and collaborators will definitely change the work market, but they won't steal job opportunities. " De Momi explains. To conduct their experiment De Momi's team photographed a human being conducting numerous reaching motions, in a way similar to handing instruments to a surgeon. These camera captures were input into the neural network of the robotic arm, which is crucial to controlling movements. Next a human operator guided the robotic arm in imitating the reaching motions that the human subject had initially performed. Although there was not a perfect overlap between the robotic and human actions, they were broadly similar. These observers determined whether the actions of the robotic arms were "biologically inspired," which would indicate that their neural networks had effectively learned to imitate human behavior. About 70% of the time this is exactly what the human observers concluded. These results are promising, although further research is necessary to confirm or refine De Momi's conclusions. If robotic arms can indeed imitate human behavior, it would be necessary to build conditions in which humans and robots can cooperate effectively in high stress environments like operating rooms. De Momi's work is part of the growing field of healthcare robotics, which has the potential to change the way we receive health care sooner rather than later. A. This future may not be as far away as we think. B. Robots can't successfully imitate doctors' motions in the operating room. C. Finally, several humans observed as the robotic arm made numerous motions. D. The nursing assistant for your next trip to the hospital will still be a robot instead of human beings. E. They will just allow us to decrease workload and achieve better performances in several tasks. F. His work indicates that humans and robots can effectively cooperate during high-risk events such as surgeries. 答案：【1】F【2】E【3】C【4】A
