One day a farmer went out for a walk with his little son. The farmer wore a pair of wrong shoes. One had thick sole(厚鞋底) but the other didn't. He began to walk and then his feet hurt. When he was just out of the house, he turned to his son and said, “Why is one of my legs longer than the other today?”
The son looked at his father's legs carefully as he was walking and then laughed, “Oh, no, Daddy. Your legs are all right. You're wearing the wrong shoes.” The farmer was very happy to hear that and said to himself, “What a clever son!” Then he asked his son to go back and got the other pair of shoes for him. The farmer had only two pairs of shoes.
When the son ran back to the house, he found that the other pair was also a wrong pair. He had to return to his father with nothing in his hands and said, “It's no use changing them, Daddy! The shoes at home are not a pair, either!”
High-tech Pollution Protection Technology company Dyson has created headphones, with a purifying visor (面罩) to help people avoid polluted air. Called the Dyson Zone, it combines noise-canceling headphones with a visor that sits just in front of the nose and mouth, providing users with filtered (过滤的) air. The device is designed to fight against air and sound pollution. Watch Your Stress When we feel stressed, our bodies produce something called cortisol (皮质的). Researchers from the University of California, US, recently developed a smart watch. It can monitor cortisol levels in your sweat (汗液) and give real- time information. The watch uses a special thin film. The film collects tiny drops of sweat. It can tell you when you have a high stress level. Remember to take a deep breath. ____ Do you like watching dandelion seeds (蒲公英种子) fly in the wind? This childhood pleasure is giving scientists some new ideas. A team from the University of Washington, US, created small, solar-powered Sensors (传感器). They fly like dandelion seeds and measure things like temperature and light. Their short "hairs" help slow their fall to the ground. |
