It is interesting to think about how people
(travel) in the future. I think cars
(use) hydrogen or electricity, not gas. They
(be) much cleaner and better for the environment. Taxis
(not have) drivers. Instead they
(move) on tracks. Planes
(probably fly) from the UK to Australia in only two hours. But people
(not stay) on Earth. Spaceships
(carry) passengers to other planets.
