    One day while driving from my home to work. I noticed a car in front of me had a wobbly(不稳定的) wheel. It was clear that the wheel had been changed recently and had not been fixed correctly. On a slow road this would not show much of a problem but I knew a highway was coming soon. There the traffic would move much faster and the driver would be in danger as the wheel could come off at that speed.

    I was driving a large jeep at the time and the car in front was a small one driven by a young lady on her own. So as I tried to flash(闪) my lights and wave her to pullover,  I was worried that she wouldn't pull over on the road side when she found in her mirror a single man chasing(追) her down in a jeep and waving for her to pull over.

    Thankfully. she trusted more in the good nature of people and pulled over where I could explain the problem. She said the wheel was changed only the night before and that she would pull into the nearest garage(修车间) where the repairman had tools to fix the wheel correctly.

    My belief is that the act of kindness was hers and not mine. How so? Well, it was she who chose to believe in the possibility that people are good over the belief that bad things would come from being waved over to the side of the road by strangers.

    I am glad I was able to wave her down in time and so a serious accident might have been avoided. But I am even happier that she believed in a stranger.

    Artificial intelligence（人工智能）, or AI in short, is the science of giving computers and machines ability to think and work like humans. AI scientists and engineers have made a lot of cool technologies.

    AI is rapidly catching up with the human ability to read faces. As a result, facial recognition（识别）is used a lot in the world. Chinese police use this technology to identify criminals（罪犯）.Once they caught a criminal when he attended a concert. It also checks the ID of ride-hailing（网约车）drivers and lets people pay for things with a smile.

    AI is also used in self-driving cars, which are believed to be the future of driving. Most drivers may wave or nod at passers-by to let them cross the street, but self-driving cars don't have this ability. Carmakers are testing a light signal system to help them "speak" to humans. The system can show what self-driving cars will do. For example, if a driverless car is yielding（让路）, it will flash two white lights side to side. A rapidly flashing light tells passers-by that the car is about to speed up.

    Service Robots also show you know powerful AI is. Imagine this—you come back home from school and your robot housekeeper is waiting for you at the door. After dinner, he teaches you to play the piano, just like a real music teacher. Such thoughts will soon happen in the real world. In the future, more and more service robots will become good home helpers.

    AI is so powerful that it can help human beings and even replace us in many jobs.
