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 0 years from now, according to the BBC.

 Digital money      

      We used to pay with cash(现金) 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(电子的) 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 people in Sweden completely stopped using cash last year, and the US might be next.

Bionic(仿生的) eye    

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 eye only allows patients to see lights and unclear shapes. A high resolution(高清的) image could be just a few years away. 

Self-driving cars     

      Unlike a human driver, a self-driving car won't get 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 stick strictly (严格地遵守)to the rules of the road and keep a safe distance from other cars. This would greatly reduce（减少） the number of road accidents. You could even take a nap while the car drives itself. In the future, driverless cars would be widely accepted.

    The Legendary Berlnuda Triangle (百慕大三角): A Mystery No More

    For years, people have believed that an area of the Atlantic Ocean between Bermuda, Puerto Rico and Florida, USA was a dangerous place. They thought planes and boats passing through here were likely to disappear. By 1964, a writer had called the area the "'Bermuda Triangle". The name stuck, and so did the mystery.

    In 1945, five US Navy planes, called Flight 19 took off from Florida and never came back. After they disappeared into the Bermuda Triangle, different ideas had begun to spread that the area was a dangerous place. Even before this famous flight, several ships had disappeared in these waters. People had many different ideas about why this appended. Some people even believed that a huge octopus (章鱼) was responsible!

    However, scientists believe that weather is part of the problem. Unusually shaped clouds above the area create strong winds that go down into the water, creating huge tsunami (海啸) waves that can take down boats or low-flying planes. And many researchers believe that there's no mystery, at all Ship goes down and plane accidents happen all over the world. It just seems to happen more in the Bermuda Triangle because there's more traffic.

    The Bermuda Triangle is also one of the deepest areas of the Atlantic, with some areas being 8 km (5 mi.) deep. So, remains are hard to find which makes the disappearances seem even more mysterious. In 2011, the Flight 19 planes were found, showing that they didn't completely disappear. But no matter how much evidence（证据） there is that the Bermuda Triangle is no more dangerous than any other part of the ocean, many still believe that you mustn't go there.

    Sun bears(马来熊)are the smallest of the world's eight bears species(物种). They have a black coat and a white or golden colour on their bodies. Their homes are in the tropical(热带雨林)of Southeast Asia. They live in trees and eat both plants and animals. They can grow to be 1.4 metres in height and 65 kilograms in weight. They usually live alone and are happy to spend most of their time by themselves.

    Scientists studied sun bears in the Bornean Sun Bear Conservation Center. They found that although sun bears live alone, they have developed a surprising social skill. They can copy (模仿) other sun bear's facial expression (面部表情) as a form of communication. They can even copy exact muscular (肌肉的) movements that other sun bears make— such as making a face.

    The ability to copy facial expressions is found in humans, gorilla's (大猩猩), some monkeys and some other animals. But until now, only humans and gorillas have the ability to exactly copy facial expressions. However, scientists found that sun bears can copy facial expression as well as humans and gorillas. This surprised them because sun bears are alone and they have no close relationship with human beings.

    Although they live alone in the wild, the sun bears in the study often played gently with each other. Sometimes they played with faster actions as hitting and biting. Scientists are still not sure what messages the sun bears were sending to one another.

    We know people can be nice, but what about animals?

    Scientists say that some animals are capable(有能力的)of being nice. Animals that live in groups-like foxes, chimpanzees(大猩猩), and elephants-follow rules. They have to follow rules to get along and to survive(生存). However, animals can act nicely, even when they don't have to. Here are some surprising stories about animal behavior.

    Most people usually walk away when someone is unkind to them. Marc Bekoff, a researcher at the University of Colorado, saw a female(母的)red fox do just that. The female fox was unhappy because a male(公的)fox played roughly(粗鲁地)with her. When she walked away, the male fox showed her that he wanted to play nicely. He lowered his head and rolled on his back. The female fox gave him another chance, and this time, he played more gently.

    Geza Teleki is a scientist who studies chimpanzees in Tanzania. One day, Teleki hiked far away from his campsite. He didn't have any food. Teleki wanted some fruit from a tree, but the tree was too tall. A young chimpanzee watched him curiously as he tried to get something to eat. The chimpanzee climbed the tree, picked the fruit, and gave it to him!

    An elephant in Kenya hurt his trunk(象鼻子). He needed help because he couldn't put food into his mouth. Researcher Kayhan Ostovar watched silently. He saw the hurt elephant show his sore trunk to a healthy elephant. The healthy elephant didn't need any more information. He took a bush and put it carefully into his new friend's mouth.

    Hippos(河马)and crocodiles are usually good friends. They hang out together in rivers. But Karen Paolillo, a wildlife expert in Zimbabwe, saw something surprising. One day, a crocodile tried to eat a monkey that was next to a river. A hippo ran quickly to the crocodile and chased it away. Why did the hippo attack(攻击)the crocodile? Paolillo says hippos sometimes protect other animals from crocodiles.

    Every year on 15th October, over 200 million people around the world take part in Global Handwashing Day. But why do we have a day for something we do all the time? Well, research shows that not enough people often wash their hands with soap. Experts believe that this leads to the deaths of millions of people every year.

    Sidibe, a public health expert says soap is the most beautiful invention in public health. Washing your hands with soap can have a huge impact on reducing (减少) the spread of diseases. Handwashing with soap prevents babies from getting ill and keeps children healthy in school.

    However, washing hands with soap does not happen as often as you might think. This is partly because there aren't enough resources (资源) in poorer countries, but it's also because for many people, handwashing is simply not part of their everyday life. It's not easy to get people to change habits they learned in early childhood -- but this is what Global Handwashing Day wants to do.

    In 2008, the Indian cricket team joined around 100 million Indian schoolchildren in washing their hands to promote (促进) the first ever Global Handwashing Day. Every year since then, many different events have been held around the world. In 2014, Global Handwashing Day was used in the fight against Ebola, a very serious disease, with events held in affected (受感染的) African countries.

    Today, local and national leaders continue to use the day to spread the message about the importance of clean hands. The hope is that handwashing becomes a necessary part of people's lives and improves the health of millions around the world.
