You will go to the kitchen when you are hungry. You will give orders to the kitchen robot. The robot will find a special food for you in a few minutes. Then it will bring it to you.

In the kitchen you will find a special food machine. The food machine will tell you what your body needs. It will help you eat healthily. The food machine will be connected with (连接) the kitchen robot. The robot can get messages from the food machine.

After having a meal, you can go to your home office. You will work at home and you don’t need to go out to work anymore.

You will have a special information screen. When you receive a message from a friend in America, your information screen will be turned on automatically(自动地). Your friend’s face appears on the screen. Then you can talk to your friend easily.

Today we find that school students hardly spend much time on sports. Is it because they aren’t interested in sports?   No, they often say they have other more important things to do.

What are important things? Exams! They have to spend a lot of time on all kinds of exams at school. So many of them almost become bookworms (书呆子). Books stop them from going out for sports. Because of the pressure from their parents and teachers, the students have to work harder and spend most of their time on books. As for the students, they want to improve their studies. So it is necessary for them to give their free time to their studies and stop their school sports.

In fact, education can’t go without exercise, because a quick mind hardly goes along with a weak body. If you don’t have a strong body, you can never get anything or any great success in your life.

The expression “ Excuse me” is more often used in the United States than in China.
