On hot summer days, Li Ming, a middle school student from Suzhou, felt uncomfortable studying in his classroom because the old fans there were too noisy and weak. To solve this problem, he decided to build a solar-powered desk fan using simple materials.
First, Li Ming collected a small solar panel(太阳能电池板) from an old garden light, a motor from a broken toy car, and a plastic bottle. He cut the bottle into fan blades(叶片) and fixed them to the motor. Then, he connected the motor to the solar panel with wires. When sunlight hit the panel, the motor turned the blades, creating a cool breeze.
However, his first design didn't work well. The fan blades were too heavy, so the motor spun slowly. Li Ming then replaced the plastic blades with lighter ones made of cardboard. He also added a switch(开关) to control the fan's speed. After testing it in the sun, the fan worked perfectly! His classmates loved it because it was quiet, energy-saving, and eco-friendly.
Li Ming shared his idea in a school science fair. A teacher suggested he add a small battery to store solar energy for cloudy days. Now, he is improving his design to make it even better.
1. What did Li Ming make to help his classroom be more comfortable?
2. Why did Li Ming choose solar energy for his fan?
3. What problem did Li Ming face with his first design?
4. How did Li Ming fix the problem?
5. What can we learn from Li Ming according to the passage? (请自拟一句话作答)
