If you see a group of kids riding bikes on a city street, and there's one adult with them, also on a bike, this is a bike bus.
It's not a real bus, but one group of 1 together does what the bus does. Take the following bike bus as an example.
Devin Olson is a dad in the US. He organizes a bike bus for local schools. It drops off students at 2 primary schools. “We 2 at 8 a.m. to play soccer and eat breakfast,” Olson says. “Then we check our 3 and start our ride. It's nothing but laughing.”
The group makes about 8 stops along the way to 4 children. “We want kids to enjoy going to school. They can ride with their parents, brothers or sisters. And they can 5 with students in different grades,” says Olson.
Recently, pictures and videos of bike buses got lots of attention 6 they were posted online. “What a simple idea it is! How 7 it is to get started,” says one internet user.
Now, many parents agree with the idea. And more 8 are giving up cars for a ride. This helps fight climate change, 9 exercise and reduce school drop-off traffic. And it also makes the children 10 than before.

What's going to happen in the future? Will robots control(控制) our planet? Will computers become smarter than us? Not possible. But scientists say something will probably happen in 10—30 years from now.
Bionic(仿生的) Eyes
They are no longer something only in a science fiction movie. The blind(盲人) may have a chance to see things clearly 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 information to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A bionic eye with very clear pictures could be just in a few years away.
Digital(数字) Money
We paid with cash(现金) for everything we bought. Now we use WeChat Pay or Alipay to shop. That means we are already using digital money. People only need to take a mobile phone wherever they go. Using these ways is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.
It's reported that people in Sweden completely stopped using cash last year, and the US might be the next.
Self-driving(自动驾驶) Cars
Unlike a human driver, a self-driving car won't be influenced by a phone call, the radio or something outside the window. Sensors(探测器) and cameras on the car will make it follow the traffic rules and keep safe. So fewer road accidents will happen. You could even take a short rest while the car drives itself. In the future, more people will use driverless cars.
