C(2026·扬州市梅岭中学期末)
Every summer, many accidents happen because of drowning(溺水). Seeing this, 15-year-old Li Ming from Zhejiang wanted to create a tool to protect people’s lives. After months of hard work, he invented(发明) an anti-drowning bracelet(防溺水手环) and won the first prize at a national youth science and technology innovation(创新) competition.
The anti-drowning bracelet is small and light, just like a normal watch. It has many smart functions. First, it has a water immersion sensor(浸没传感器)—if it stays in water for more than 18 seconds, it judges that a drowning may happen. Then, a built-in airbag inflates(充气) in just 2 seconds, creating enough buoyancy(浮力) to lift the person to the water surface with their face up. At the same time, the bracelet sends an alarm with precise(精确的) GPS location to the guardian’s phone app via 5G.
To make the bracelet reliable(可靠的), Li Ming tested it many times. He tried different materials for the airbag and adjusted the sensor’s reaction time. “Once, the airbag didn’t inflate quickly enough,” he said. “I spent a whole week improving the gas cylinder(气瓶) design, and finally it worked perfectly.” The bracelet is suitable for rivers, lakes and swimming pools.
Li Ming’s invention has won great praise. Experts say it can save precious(珍贵的) time in rescue(救援)—since the “golden rescue window” for drowning is only 4 to 6 minutes. His story inspires(鼓舞) many students: “We don’t have to be adults to make a difference. Paying attention to the problems in life and trying to solve them can lead to great creations.”
