13. Text
Host: Will you tell us about the new intelligent
home your company has built? It promises
to be the model for the houses of the future.
Grace: Certainly. The idea is not to have a house full
of gadgets. This is a complete household
system. It will make people’s lives easier.
Host: OK. So tell me how this will make my life
easier?

14. Grace: When you arrive at the front door, you won’t
need a key. The door will open with a touch of
your finger: the system recognizes your
fingerprint. You will be able to call your
refrigerator when you are in the supermarket
and find out how much milk you still have and
figure out how much you need to buy. Isn’t
that wonderful?
Host: Can I call the washing machine as well?

15. Grace: Sure. But you won’t need to. The house
comes with a robot. Greeves has been
programmed to do the cleaning, the
washing, and the ironing.
Host: What about household problems?
Grace: Well, if a pipe bursts, the house will call
the plumber. And if there’s a fire, the
house will turn on the fire extinguishers
automatically and call the fire
department.

16. Host: And what’s the price of this intelligent
home?
Grace: A million dollars.
Host: A million dollars! It will be the twenty-
second century before I’ll be able to afford
to buy one!
