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.

No one knows when the first kite was made. The first record of a kite was more than 2,000 years ago in China. Han Xin, the leader of an army, wanted to bring down a king. He decided to dig a tunnel (隧道)into the king's palace. He flew a kite over the wall of the palace to make sure the length (长度)of its string (线).In this way, he could determine how long the tunnel should be. His men in the tunnel took the kite string with them. When they reached the end of the string, they knew to dig up.

    Kites have been flown in Japan for hundreds of years. In the 1700s, kites were flown in autumn to give thanks for a good harvest. They were also flown to send good wishes to couples who had their first son. Today in Japan, kites are often flown as part of a celebration, such as the beginning of a new year. And kite festivals are held each year in many parts of the country.

    Kites have been used for scientific purposes in the western world. In 1752，Benjamin Franklin tied a key to a kite and flew it in a storm to find out that lightening was a form of electricity. In the 1890s, Lawrence Hargrave invented the box kite to test ideas about flight. From 1898 until 1933, the United States Weather Bureau (气象局) used box kites to collect weather data. The Wright brothers also experimented (试验)with kites. What they learned helped them make the first airplane flight in 1903.

    Give your dead batteries a new life. Recycle them！

    Batteries(电池) are used to power clocks, computers, tools and more. However,

Your batteries have some serious power when their lives are over.

WHY TO RECYCLE BATTERIES

    Remember, batteries are harmful waste. This mean you could properly throw away. You may not think one little battery can cause that much pollution. But don't think of it as just one battery—there can be millions. In Canada, each person uses about 20 single-use batteries every year. That's about 700 million batteries! If all these batteries end up in landfills(垃圾填埋场), the heavy metals inside them can get into the water, land and air. It can be harmful to humans and wildlife.

    By recycling single-use batteries instead of throwing them away, you can cut down pollution and also help save energy. All batteries are mainly made of plastic and valuable metals. Through recycling programs, dead batteries can be changed into something useful like steel products, or even new batteries!

    HOW TO RECYCLE BATTERIES:

    Make a difference by starting to collect batteries at your home or school today. You can prepare a box for battery collection and invite friends, family and classmates to bring in old batteries to be recycled.

    There are many safe ways to deal with your batteries. You can:

    Find a Call 2 Recycle public collection station near you.

    Ask the store where you bought the batteries if you can return them there.

    Communicate with your local city government to find out if there are special programs for recycling used batteries!

    China's first artificial intelligence (AI) textbook series designed for primary and secondary school students is expected to be introduced into hundreds of campuses across the country in 2019. The textbooks will be used for elective courses or as part of school﹣based curriculums.

    Significant progress is being reported in China in AI technological research and development, with authorities now moving to promote AI﹣related education.

    According to the publisher, East China Normal University Press, the series will have 10 volumes, with six volumes published so far. Each has its own theme, with 12 to 14 main chapters and 2 to 4 chapters of activities. This series covers the educational demands of students from primary school to high school on AI and provides a systematic framework of AI knowledge.

    The books have been used in three schools in Shanghai as a pilot program and well received by students, according to Wang Jiqing, chief editor of the series.

Language learning begins with listening. Children are greatly different in the amount(数量) of listening they need before they start speaking, and children who start speaking late are often long listeners. Most children will"obey (服从)"spoken instructions some time before they can speak, although the word"obey"can almost not describe the cooperation (合 作)shown by the children. Before they can speak, many children will also ask questions by gestures and by making noises.

People agree that babies enjoy making noises, and that during the first few months babies use one or two special noises to show their happiness, pain, friendliness and so on. But since these are not a kind of communication, language. From about three months old they play with sounds for enjoyment, and by six months they are able to add new sounds to their words. This self-imitation (自 我 模 仿) leads to deliberate(故意的) imitation of sounds made or words spoken to them by other people. The problem then appears — can people take these imitations as speech?

It is a problem we need not get our teeth into. The meaning of a word depends on what a special person means by it in a special situation, and what a child means by a word will change as he or she gets more experience of the world.

Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself or herself. I wonder, however, whether anything is gained when parents try to use this ability to teach new sounds.
