Read the article and title a–f each paragraph 12–16. There is one title you do NOT
need to use.
a) Saving sea resources
b) Distant operating
c) No kitchen
d) Replacing meat
e) New eating habits
f) More veggies
What’s cooking?
(12) Tomorrow’s children will eat differently from their parents. Many modern
homes don’t have a dining room because the occupants usually eat meals in front of
the television. In the future, families eating together at home will be an unusual event.
Food will be heated in a microwave. If there is a cooker, it will be on a dining table
rather than in the kitchen.
(13) The kitchen of the future will be intelligent! Thanks to automation, it may
be possible to call home on a mobile to start a cooking programme. There is nothing
better than to come home after a long working day to see your dinner ready. With
such a kitchen you can easily organize a party for your friends.
(14) In the future, fewer Europeans will eat meat because they think that other
foods are better for their health. In addition, farmers will realise that growing crops is
a more efficient use of land than raising cattle. “Every time a person gives up eating
beef,” says food expert Brian Ford, “three thousand square metres of land are freed
for crop production.”
(15) But meat is a major source of protein. How will we get the protein we
need without meat? The answer is: from plant sources. Mushrooms and other fungi
will be specially grown, fortified with vitamins and artificially flavoured. Artificial
flavouring will become widespread.
(16) According to Ford, fish will always be popular. “Fish, especially oily fish,
have much to contribute to the diet of the future. The problem is that we are catching
too many fish. We need to reestablish sanctuaries – “national parks” – in the oceans
where fish are free to multiply.”
