What's going to happen in the future
What's going to happen in the future？Here are some things that scientists say is most likely to happen 10to 30 years from now.
1 Digital money
We used to pay with cash for everything we bought. In fact，we are already using one type of digital money，when we swipe（刷卡）our bus pass or use a credit card to shop online.
You have to admit that using a card is much easier than searching your pocket for change. It is also safer than carrying a lot of cash on your person. People in Sweden completely stopped using cash last year and the US might be next.
2 Bionic（仿生的）eye
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 into the brain.
Although the bionic eye that's out now only allow patients to see lights and unclear shapes，a high resolution（分辨率）version could be just a few years away.
3 Self-driving car
Unlike a human driver，a self-driving car won't be distracted（分神）by a phone call，the radio or something outside the window. Sensors（探测器）and cameras on the car would allow it to keep strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents Many vehicle companies are now planning self-driving cars. By 2040，driverless vehicles will be the main vehicles on the road.

We have always been interested in the Moon. 2,000 years ago people already knew it circles around the Earth and it is in different places in the sky at different times of the year. At that time, everything about the Moon was learned by watching it carefully in the sky.
When scientists could use telescopes to study the Moon more clearly, their ideas began to change. They could see that there were lots of rocks on the surface of the Moon. Most scientists thought Moon rocks would be different from the rocks on the Earth.
In 1969, Moon rocks were finally brought to the Earth and studied. Much to their surprise, scientists found that, except for water, the Moon and the Earth were made of the same things. Once again new ideas came out according to the new information.
After years of study, most scientists now think that the Moon was once part of the Earth. They believe about 4 million years ago, something of the same size as Mars hit the Earth. This sent billions of rocks into space around the Earth. These rocks slowly joined together and finally became the Moon.
In the future, our ideas about the Moon may change again. However, we will still be interested in the Moon.
