Unit 2 Nature in the balance (译林版2020必修第三册) 单元话题阅读精练(阅读理解15篇+七选五5篇) Ⅰ. 阅读理解 A (2024上·内蒙古乌兰察布·高一统考期末)The Yellow River is the cradle of China’s civilization. And flood control and prevention have always been key to the wellbeing of the people living along it. Now, scientists can better work on these issues by giving the river a digital twin. The digital twin of the Yellow River uses various technologies, including big data, artificial intelligence, and the internet of things. Devices(设备) set up along the river collect and transmit information to the center. Based on the information, a 3D model of the river is presented on the computer screen. It’s like the Yellow River has a twin that reflects its real conditions. One big breakthrough in the river’s digital governance(治理) is “smart stones”. According to Wang Qin, a lead researcher at the Information Center of Yellow River Henan Bureau, a smart stone is a water-proof stone-shaped device with chips, a battery, and a signal transmitter. They are buried in important dike(堤坝) locations to record and report the movement of dike stones. “Upon feeling movement of the dike stones, the smart stone sends an alarm to the center for quick response,” Wang said. “In the past, researchers had to learn the conditions of the dike on the spot by themselves, putting their lives at risk,” said Zhao Xiao from the bureau. “Now the smart stones can do this for us, more safely, quickly, and accurately.” And in the sky, drones(无人机) are flying. On the routes designed by engineers, the drones become expert patrollers(巡逻员) of the river, looking at its dikes and flood prevention projects. According to Shen Lin from the Yellow River Conservancy Commission, thanks to the drones, researchers at the command center can get first-hand photos and information. “Researchers then update the 3D model according to the changes the drones reported. The newly updated model helps us test our floodwater release plans in case we ever need to batten down the hatch
