Four students are talking about the future after class.

Deng Yu:  In 2050, China will be richer than it is now. Beijing will be getting ready for the 40^th Olympic Games in 2050. We will see the blue and clear sky and smell the fresh air. There will be more pandas living happily in China. I believe that 2050 will be the year of China.

Liu Yan:  A holiday to the moon will no longer be a dream. We can also travel far to other planets and talk with spacemen. We might also eat something like pills instead of today’s meals. Everyone will enjoy a longer life.

Sun Wei:  Robots will be more popular. They will do what people don’t want to do. We’ll build new homes on other planets. By then, I’ll be sixty years old.

Zhang Lan:  By the year of 2050, cloning will have been used in many ways. It will bring back animals which disappeared many years ago. There will be no pollution. The whole world will be one big family. There will be no wars. We’ll live a much easier and better life.
