No one knows what would happen in the future for sure. But we often 41 the future and wonder 42 the world would be like in the future.
Think of space. Perhaps a permanent station on the moon will have been 43 . Perhaps people will be able to visit the moon as 44 . Cheap rockets for 45 travel will have been developed, permitting long 46 throughout the solar system. When that time comes, people will be 47 holidays in space and visiting other planets, 48 the Mars and the Venus.
Scientists of the future will almost certainly find other ways to make life last 49 . They probably will find cures 50 most diseases. Hospitals will probably have "body banks" that can give you almost 51 new part you need to keep on living. People of the future may live to be 52 older than 100 years.
Maybe the most wonderful surprise in the future will be 53 control. Cities may have giant plastic domes(圆屋顶) 54 them to keep out snow, rain, or storms.
The entire world will have been developed— 55 Antarctica. There will be large cities in Antarctica. We already have supersonic(超音速的) flight, but in a hundred years' time we will have supersonic land travel 56 .
We will have 57 most of the earth's land to build our cities, so floating 58 will have been built. Monaco has already built homes, stories, and offices 59 the water of the Mediterranean(地中海). And an architect has proposed a 60 for constructing buildings on bridges over the Tokyo Bay. And there will be cities under the sea.
