Our Future Homes
 What kinds of homes will we live         the future? Nobody can be sure,         architects, and scientists are         new ideas now.
  Some architects are thinking about          whole cities under huge glass domes. Of course, complicated heating and        systems will be necessary to control the climate in the domes.        , there will never be any rain      snow, and the temperature will be always        .
  Perhaps everyone will live in vertical(立体的)       . High rises are so large that they can contain all the necessities of life. Since vertical cities will use        land than horizontal cities, and provide homes for more people, they will be       for small countries that have     populations.
Another idea that will be helpful to        countries (and island countries) is
the      city. Monaco has already built homes, stores, and offices         the water of the Mediterranean Sea. And a Japanese       has made a plan for constructing buildings on bridges over Tokyo Bay.
  There are some people who think we will go back to living in       . But the caves of the future will be quite      the caves of the Stone Age. Computers will control light and climate. Farms and parks will be on the land      the cave city. When people want to go to the country or to a park, a short ride in       will take them there.
