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（面部识别）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 how 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.

People read books less often in these days. With the invention of radio, television and most recently, the Internet and computer games, it seems that reading books is no longer a popular activity. However, I believe that books are an important part of our lives.
Books offer an outstanding wealth of learning and at a cheaper price than taking a course. Books can make people cleverer, because heavy readers have greater knowledge of how things work and who or what people were.
Everything in today’s society requires reading. Imagine trying to do something as simple as reading the directions on a medicine bottle without good reading skills. Someone could not understand them and become very sick or even die.
Even something as simple as walking or driving through the city could become very dangerous without enough reading. Sometimes, you must be able to understand what is written and explain the meaning of them.
Some people say that reading is a waste of time and we can do better things with our time. Even if we don't read books, we still read every day, and reading books can strengthen (加强) our abilities. Reading is one of the greatest things we can do in our spare time.
With a book, you can travel anywhere you want, do anything you want, and talk to anyone you want. Reading is very important in our lives, no matter your age. So I think people should read books.
