(2018·河南实验中学模拟)At the end of every year, Time picks the best 25 inventions t hat are “making the world better and smarter”. Here we have picked three of this year’s inventions that could be a part of your life in the near future.The levitating(悬浮的) light bulbThis special light bulb was invented by U.S. artist and scientist Simon Morris. He got the idea of making a light bulb float from hoverboards(悬浮滑板), which he used to dream of having as a kid.But the floating is not the most amazing part. The rejection force between the opposite ends of the magnets(磁铁), which were put in the bottom of the bulb and in the wooden base, does the job. What’s new here is a technology called induction(电磁感应). It allows the light bulb to get power from the base even they are not in contact.Shoes that tie themselvesThey’re not what you think—shoelaces that tie themselves in the way we tie them. Instead, the new shoes have small motors that control their laces. When you step into them, your feet will hit a sensor(传感器) in the shoes and the motor will automatically tighten the laces.But the shoes weren’t just designed for lazy people’s needs. They could actually give athletes an advantage during competition. They are also useful for people who cannot move their arms or fingers easily.The no touch thermometer(体温计)Taking your body temperature usually means putting a thermometer in your armpits(腋窝) and staying still for minutes. It may be easy for you, but it’s an impossible task for little kids.Now, with the new thermometer, users can simply put it 2.5 centimeters from a patient’s forehead and press the button, and it can get reading in two seconds.【解题导语】每到年终岁尾,《时代周刊》都会评选出25项“让世界变得更加美好和智能”的最佳发明。
