Do you know the movie I, Robot? It tells us a story about the future.
The year is 2035 and robots are just as common as mobile phones. People depend on their robots to do lots of things, for example, babysitting, cooking, and taking their dogs for a walk. Robots have to listen to humans' orders, because their inventors make them do so. A police officer called Spooner hates robots. He doesn't think humans can get on well with their robots at all! But the scientist Susan has different opinions. Susan works on robots' mind and she thinks one day robots will become more powerful (强大的) than humans and help humans to make improvements.
When Spooner and Susan work together, they find that something is wrong with the world's robots. A few robots have their own thoughts and they're trying to get out of humans control (控制)! Of course, these robots' dream doesn't come true. Humans work hard to control their robots again and they succeed at last.
