Four students are talking about the future after class.

Deng Tao	In 2050, China will be richer than it’s now. Shanghai will be getting ready for the 40th Olympic Games in 2052. We’ll see the blue and clear sky and breathe the fresh air. There will be more pandas living happily in China. I believe that 2050 will be the year of China.
Lin Hong	A holiday on the moon will no longer be a dream. We can also travel far to other planets and talk with the spacemen. We might also eat something like pills that take the place of today’s meals. Everyone will enjoy a longer life.
Wang Jun	Robots will be very popular. They’ll do what people don’t want to do. We’ll build new homes on other planets. By then, I’ll be fifty years old. Maybe we’ll have an exciting talk in my new home on another planet!
Li Ping	By the year of 2050, clothing() will be used in many ways. It’ll bring back animals that disappeared many years ago. There will be no pollution. The whole world will be one big family. There will be no wars. As time passes, we’ll live a much easier and better life.
