U4 reading 语法填词 Imagine 1 (wake) up one morning with the option of staying in bed and pressing a button to send a robot to do all the work for you. How cool that would be! It may seem like building castles in the air, but 2 (give) the rate at which artificial intelligence, or Al, is being developed, in the future such dreams may actually come true. 3 the basic level, artificial intelligence is a branch of computer science that aims 4 (create) intelligent machines. One of the essential aims of Al is to develop computer intelligence capable 5 learning from experience, adjusting 6 new inputs and performing tasks like humans. To achieve this aim, many approaches to creating a true Al have been put forward, including "deep learning”, which 7 (able) a machine to improve its own performance by learning from the results of its previous actions. Deep-learning Al has the capacity to analyse massive amounts of data through multiple layers, imitating the complex networks of the human brain.The dream of Al has been around for centuries, and the development of computers .since the 1940s has finally made it 8 reality. Years before the term "'artificial intelligence" 9 (coin) in the mid-1950s, the theory 10 (explore) byAlan Turing, one of the pioneers in the field of computer science. However, for a long time, Al technology developed very slowly. A major breakthrough in Al came in 1997, when Deep Blue, a chessplaying computer, beat the world chess champion Garry Kasparov. Then in 2017, a computer program 11 (name) AlphaGo defeated Ke Jie, arguably the best human Go player, 12 demonstrated a significant advance in deep-learning Al systems.Nowadays, Al is already being applied in many fields: finance, health care, machine translation and art, to name but a few. From autonomous vehicles to domestic robots, from recommendation systems to computers writing novels, Al has an unlimited number of applications. Ordinary people are now using Al to get instant translations of text in foreign languages, and machines can recognize fingerprints and even faces.In short, this technology is transforming the way 13 we live. It is clear 14 we are at a turning point in history. 15 machines like AlphaGo now capable of thinking and learning from their mistakes, we are getting closer to the dividing line between humans and machines. The question is, where will all this lead While Al enthusiasts promise us a bright future where intelligent robots will be working 16 our advantage, these undoubted benefits also bring concerns and fears. Could machines really develop human-like intelligence And what would happen if they did Would thinking machines work alongside humans or threaten the 17 （exist) of humans How would they be punished if they committed crimes or even murdered humans As we become more and more 18 （depend） on computers, some scientists are urging us to think about the dangers 19 （pose） by the advances in Al. Stephen Hawking, for example, warned, “The development of ... ...
