I. Read the text, then do the tasks. The home of the future When you're out of the house, is the fridge on the phone to the supermarket? Is the heating system having a word with the bath? And when you get back home, does the doorknob recognise you and say hello? Probably not, but in the house of the future all this - and more - is possible. Researchers say that technology will transform your home in ways you can only dream about. Nanotechnology will play an important role. It will clean your windows.
