It's true that there are some bad people on the internet. They try to get your money or information. So it is necessary to be careful of the internet. However, staying safe online doesn't ask you to turn your internet off. The following advice will help you keep away from dangers on the internet. ●Check the links(链接) carefully You may often need to click(点击) links when you check your emails or read online. Before clicking them, you should make sure they are safe. There's a good way to tell whether a link is safe. First, put the mouse over it and the full link will appear near the mouse. Then you can check whether this link is an official(官方的) website. If it is, then you can click it. ●Don't share your personal(个人的) information You should never tell others your own information online, such as your family information and bank information. You should also know that anything you post on the internet may stay there online for a long time. So, be careful about anything you post on the internet. ●Remember to use a safe public Wi-Fi If a public Wi-Fi is open for everyone, it may be not safe. You'd better not use such a Wi-Fi. When you have to use one, don't enter in(输入) any personal information. |
Over the past few years, cars have become smarter and smarter. Some of them can even drive themselves. Now, our roads have followed the steps. In the United Kingdom alone, there are around650 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(给……充电)
Global warming has forced us to search for new energy sources. Why not look to the roads? Piezoelectric roads, a new kind of smart road, use vibrations(震动) from passing cars to produce electricity. In fact, Piezoelectricity was invented in
1880. However, it has never been widely used before now. The U. K.'s Lancaster University is going to improve it.
▲ Built- in brain
Roads of the future may be able to know how many people are on them, send drivers updates(最新的情况) on weather and traffic jams, and recharge electric cars while driving.
This seems impossible, but one American company has almost made it come true. By sensing the weight of a car, the smart roads can track the speed of each wheel. The smart roads are like large touchpads(触摸屏) so that they can collect data(数据) by looking for wheels. And then the roads will send it to the drivers.
▲ Roads that never freeze
It can be dangerous to drive in snowy weather. A tech company in Israel has developed the Snowless roads. When they find snow or ice on their surfaces, the roads will heat themselves up, melting(使融化) them away. The company has succeeded in testing this project on a few Canadian roads and in some of its car parks.
