Over the past few years, cars have become smarter and smarter. Some of them can even drive themselves. Now, our roads have followed suit (跟着做) . In the United Kingdom alone, there are around 650 kilometers of “smart roads” in use. Across the world, many more are being built. Some new technologies are being put to use.
Roads that recharge (充电)
Global warming has made us search for new energy sources. Why not look to the roads? With the right technologies, cars around the world could be producing energy as they go. Piezoelectricity ads mix traditional asphalt (柏油) with new material. They use vibrations (振动) from passing cars to produce electricity. In fact, piezoelectricity is nothing new. It was invented in 1880. However, it has never been widely used before now. The UK’s Lancaster University is going to change that. It has been improving the technology, including developing roadside batteries that can store the electricity.
Roads that never freeze
________ A tech company in Israel has developed the Snowless roads. When they detect snow or ice on their surfaces, the roads will heat themselves up, melting the snow or ice away. The project has been successfully tested on a few Canadian roads and in some of its car parks.
Built-in brain
Roads of the future may be able to know how many people are on them. They could send them updates (实时信息) on weather and traffic jams, and recharge electric cars as they drive. This seems to be a dream, but one American company has almost made it come true. By sensing the weight of a vehicle, the company’s smart roads can track (跟踪) the speed of each wheel. “We are basically making very large touchpads,” says Tim Sylvester, CEO of the company. “but instead of looking for fingers, our roads look for tires.” After having collected traffic data, the roads will send it to the drivers.

【分析】
文章主要从不同的几个方面介绍了未来道路的情况。
1. 细节理解题。根据 “In the United Kingdom alone, there are around 650 kilometers of “smart roads” in use. Across the world, many more are being built.” 可知, “ 智能道路 ” 在一些国家已经开始使用,故选 D 。
2. 推理判断题。根据 “A tech company in Israel has developed the Snowless roads. When they detect snow or ice on their surfaces, the roads will heat themselves up, melting the snow or ice away.” 可知,这里应该是说开发无雪道路的原因,应该是下雪天开车是危险的,选项 C“ 在下雪天开车可能是危险的 ” 属于开发无雪道路的原因,故选 C 。
3. 细节理解题。根据 “ “We are basically making very large touchpads,” says Tim Sylvester, CEO of the company. “but instead of looking for fingers, our roads look for tires.” After having collected traffic data, the roads will send It to the drivers.” 可知, Tim Sylvester 主要是解释道路的工作原理,故选 A 。
4. 推理判断题。根据 “A tech company in Israel has developed the Snowless roads.” 可知,以色列的一家科技公司开发了无雪道路,故选 C 。
