学科网(北京)股份有限公司 中考热点阅读理解—冬奥会 During the Beijing 2022 Winter Olympics, athletes (运动员) from all over the world broke both personal and Olympic records. High-tech elements have been giving “wings” to these hard-working athletes, helping them become “faster, higher, stronger”. The National Speed Skating Oval (国家速滑馆) (the Ice Ribbon) saw 12 new Olympic records and one world record, including Chinese speed skater Gao Tingyu’s Olympic record of 34.32 seconds in the men’s 500 meters. Known as “the fastest ice”, the 12,000-square-meter rink (冰场) has received very good feedback from the athletes. “It makes everyone skate faster,” Gao Tingyu said after he bagged the gold. The secret behind is a new carbon dioxide (一氧化碳) ice-making technology. Speed-skating requires a very flat (平滑的) ice surface. If the ice surface temperature doesn’t change much, the ice stays flatter. Flat ice is easier to skate on.Liguid (液态的) carbon dioxide was put under the ice for the first time. It cooled the ice and kept the temperature changes on the surface within just half of one degree. In events like freestyle skiing and ski jumping, the direction and speed of the wind could largely affect athletes’ performance. A research team from the Chinese Academy of Sciences developed a wind measuring (测量) system using AI technology. “Some events only last a few seconds, and the wind is changing all the time. This system allows athletes and coaches to ‘see’ wind directly through real-time data (数据) on their pads, and decide when and where to jump,” the team leader Shao Yun told Beijing Daily. There are many more high-tech elements that boost athletic performance, including drag-reducing (减少阻力的) sportswear, smart beds that massage (按摩) athletes, and robots that cook. All these helped keep China’s promise to hold an “athlete-centered” Olympics, said Zhao Weidong, the spokesperson of the Beijing organizing committee. 学科网(北京)股份有限公司 1.Gao Tianyu set a record for ________.
