The villagers? observation.31. What is the writing purpose of the passage?A. To describe the beauty of Hui architecture.B. To explain how people live in harmony with nature.C.To attract tourists to visit cultural heritage sites.D. To praise the creativity of people in Xidi and Hongcun.DResearchers at UC San Francisco have developed a brain-computer interface (BCI) that allows aparalyzed (瘫疾的） man to control a robotic arm using his thoughts. The device, which translates brainimagining the actions. Remarkably, the BCI functioned for a record seven months without requiringadjustments, a significant improvement over previous systems that lasted only a day or two.The breakthrough relies on an AI model that adapts to subtle changes in brain activity as a personrepeatedly imagines performing a movement. This adaptability allows the system to better itsperformance over time. “This blending of learning between humans and AI is the next stage forbrain-computer interfaces,” said Dr. Karunesh Ganguly, a neurologist at UCSF. “It's what we need toachievesophisticated,lifelike functionThe study, funded by the National Institutes of Health and published in Cell, focused onunderstanding how brain activity patterns shift over time. Ganguly and his team discovered that whilethe brain's representations of movements remain consistent,their locations change slightly from day today.By programming the AI to account for these shifts, the BCI maintained its functionality for months.The participant,who was paralyzed by a stroke,had tiny sensors implanted on his brain to detectactivity when he imagined moving. Over two weeks, the team trained the AI by having him imaginesimple movements, such as moving his fingers or hands. Initially, the robotic arm’s movements wereimprecise, but after practicing with a virtual arm that provided feedback, the participant improved hiscontrol. Once he transitioned to the real robotic arm, he quickly mastered tasks like pickingup blocks,opening cupboards, and holding a cup to a water machine. Even months later, he could control the armafter a brief "tune-up" to adjust for changes in his brain activity.Ganguly is now improving the AI to make the robotic arm faster and smoother, with plans to testthe BCI in home settings. For individuals with paralysis, this technology could be life-changing,enabling them to perform everyday tasks independently.“I'm very confident that we've learned how tobuild the system now, and that we can make this work," Ganguly said.32.How doesthe paralyzed man control a robotic arm through theBCI?A. By using his thoughts.B. By adjusting the device.C. By translating brain signals.D. By improving the present system.英语试题第6页(共10页)6/1033.Whichof thefollowingis afeatureoftheAI model?
