What are the things going to be like in the future?Can you guess?
You wake up at seven o'clock.Your breakfast may be ready for you to eat.People needn't cook.Now you start for work.But you don't go by car.You get in a moving sidewalk（自动人行道）.It carries you to a train station.There you take a train.
Three o'clock comes.Your work is over in the day. "I'll call my friend，John." You say.John answers the picture phone.You and he can hear and see each other. "What will you do this Saturday?" You ask， "Will you come and visit the under water park with me?" John may says， "I want to take a spaceship!Let's fly to the Moon!"
