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 dont 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 lash 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 how powerful Al 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
