In the future, we live in amazing new homes. Our houses will use the sun or the wind to make electricity. We won’t

have cookers, dishwashers or washing machines. We will have robots to cook our dinner and wash our clothes. We will have

robots to look after our children, and to feed our cats and dogs.

We won’t use computers. We will have special remote control units. We can surf the Internet, send and receive e-mails and

order food from the markets without getting out of bed.

We won’t have TVs or CD players because we will have watches that play music, take pictures and tell time. Our cars might

not use gas. They might use energy from air, water or plants.
