Question

　　Some building designers are thinking about building whole cities under glass domes(圆顶) in the desert. Of course those heating and cooling systems(系统) will be necessary to control the climate in the domes. However there will never be any rain or snow and the temperature will always be comfortable.

　　Perhaps everyone will live in high vertical(垂直) cities that are so large that they can contain all the necessities of life. Since vertical cities will use less land than horizontal(水平的) cities and provide homes for people they will be practical for small countries that have a large population.

　　Another idea that will be helped to small countries and island countries is the floating city. Monaco has already built homes stores and offices on the water of the Mediterranean Sea. And a Japanese designer has suggested a plan for constructing building on bridges over Tokyo Bay(湾).

　　There are some people who think we will go back to live in caves. But the caves of future will be very different from the caves of the Stone Age. Computers will control light and climate. Farms and parks will be on the land over the cave city. When people want to go to the country or a park a short ride in a lift will take them there.
