【题目】

Artificial intelligence(AI in short人工智能) can give computers and machines ability(能力) to think and work like humans. AI scientists and engineers have made much progress in this field.

Facial Recognition

AI is rapidly catching up with the human ability to read faces. Facial recognition(识别) is used widely in the world. Chinese police use this technology to identify(认出) criminals(罪犯). They had caught about 50 criminals at Zhang Xueyou's concerts by October, 2018. It also checks the ID of ride-hailing(网约车) drivers and lets people pay for things with a smile.

Self-driving Cars

Most drivers may wave or nod at passers-by(路人,行人) to let them cross the street, but self-driving cars don’t have this ability. Car makers are testing(测试) a light signal system(灯管信号系 ) to help them “speak” to humans. For example, if a driverless(无人驾驶) 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(加速).

Service Robots

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.
