Some people, in all seriousness, say that humans

years. Planet Earth will be crowded, dirty and lack of 【S1】______
resources. A sort of exodus (移居) of mankind will
begin.

the first space bus launch in April 1981. This was 【S2】______
"Columbia", it made several orbits around the earth and 【S3】______
then returned, landing on a huge dry lake bed in
California. "Columbia" will be used again. Previous
spaceships have been abandoned, only the nose cone
being used to bring the crews back to earth. 【S4】______
Upon established, each space station will generate 【S5】______
its own atmosphere and have its own agriculture. It will
need to rotation to provide an artificial gravity; people 【S6】______
will be forced inwards from the centre by centrifugal 【S7】______
(离心力) force.
The moon and Mars could become new sources of
new materials. Driving through space will no longer 【S8】______

work magnetic rockets.
That all sounds quite fantastically but, with the 【S10】______
rapid development of modern technology, who knows
about what the future holds? [br] 【S9】
