What's going to happen in the future? Will robots control our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen in 10 to 30 years from now, according to the BBC.

Digital money

    We used to pay with cash for everything we bought. Now when we use a credit card(信用卡) to shop online, money is spent without us seeing it. That means we are already using digital money. Using a card is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.

    When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. It's reported that Sweden will first completely stopped using cash, and the US might be next.

Bionic(仿生的) eyes

    It's no longer something only in a science fiction movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.

    A blind eye can no longer sense light, but a bionic eye can use a camera to "see" the environment and send data (数据) to the mind. Now the bionic eyes only allow patients to see lights and unclear shapes.

Self-driving cars

    Unlike a human driver, a self-driving car won't get distracted(分神) by phone call, the radio or something outside the window. Sensors(传感器) and cameras on the car would allow it to reduce me number of road accidents. You could even take a nap while the car drives itself. In the future, driverless cars would be widely accepted.

    A young woman traveled and stayed in a hotel. All the rooms in the hotel were singles(单人间). So she lived in a single room.

    Just when she was going to bed, there was a knock at the door. She had no friends in the city. So she was quite surprised but still opened the door.

    The man who was standing at the door looked a little nervous. "Oh! I'm sorry. I thought this was my room," the man said and walked away in a hurry.

    The woman called the police at once. Soon, the man was caught. He was a thief(小偷)! But how did the woman know that?

    All the rooms in the hotel were singles. Who would knock at his own door if he was staying alone? Only a thief would do this. He wanted to see if anyone was inside before he broke into the room.

    Two men are walking in the park. One is Mr. Brown, a worker, the other is Mr. Black. Mr. Brown is going to a chair. It is beside the road. Mr. Black is after him. Mr. Brown finds Mr. Black. Now Mr. Black begins to walk faster (更快), because he wants to get to the chair before Mr. Black. Now Mr. Black begins to walk faster because he also wants to get to the chair first. Then they both run. Mr. Black runs faster than (比) Mr. Brown. So he gets to the chair first and sits down on it. Mr. Brown runs after Mr. Black. When he gets to the chair, he sees Mr. Black sitting on it. He is sorry to show a notice (通知) with the words "Wet Paint (油漆未干)" to Mr. Black. Now Mr. Black knows why Mr. Brown is going to the chair.

    Nigel is our new next-door neighbour. He's a pilot. He was in the R.F.A. He will fly to New York next month. The month after next he'll fly to Tokyo. At the moment, he's in Madrid. He flew to Spain a week ago. He'll return to London the week after next. He's only forty-one years old, and he has already been to nearly every country in the world. Nigel is a very lucky man. But his wife isn't very lucky. She usually stays at home!
