Life in the twenty-first century
The World Future Society is a group of people from more than 80 countries who are interested in how modern technology is making our world better, and who write reports about how it will change our lives.                                                                                                                                            The things that we will be able to do in the twenty-first century (since the year 2000) should help us live better lives in many ways, at home and at work, in our own country and around the world. Here are just some of them, put into five groups.
People
People may live for up to 120 years and use new technology to help when people go blind, deaf and have other problems. The number of people over a hundred years old could go from 135,000 today to 2.2 million people by 2050. By 2015 people think that 100 million workers will be able to work from home for a company in a different country by using the Internet.
Money
Worldwide e-business will become even more successful with online shops that sell special products for each person, which will be brought to their house the next day.
Environment
The technology for making energy from wind and the Sun is growing very quickly. In the future wind and Sun energy could become much cheaper and many more countries could use it. This would be very useful in poor countries. The air in big cities would also become much cleaner and healthier as a result.
Society and culture
The Internet will help to create more worldwide friendships. Families may spend more time together as people will be able to do 24-hour online banking and shopping.
Technology      
The new science of “nanotechnology” (very small robots or machines) will make all sorts of products smaller and lighter. Very, very small machines could take away rubbish, make things in factories, and help inside the human body by taking away fat. By 2012 people will be able to wear these small machines that look like watches, which will give them lots of information about their body and keep them healthy

One Sunday morning, I decided to buy a computer to use for school. I went to the biggest store in town, which sold all kinds of computers. There were so many computers there that I didn’t know how to choose a right one.
“Hi! What can I do for you?” A young man greeted me with a sweet smile. He looked like not a salesman but a student like me. I had a strange feeling—as if I had met him before. He began patiently showing me each model. With his help, I decided to buy one computer with enough functions at a very low price. I enjoyed this shopping experience because of his smile. A few months later, something was wrong with my computer. I went back to the store to have it fixed. When I arrived there, what I saw first was still his smile. As soon as I told him my problem, he comforted me immediately and tried his best to solve the problem for me. I was quite grateful to him for his sweet smile and good service (服务).
When I went back to school, his smile often appeared in my mind. I don’t know whether we’ll meet each other again, but his sweet smile will stay there in my memory and deep in my heart. Smiling is the most peaceful language in our life.
