D
We often think of future. We often wonder what the world would be like in a hundred years’time.
Think of space，perhaps a permanent(永久的) station on the moon will have been set up. Perhaps people will be able to visit the moon as tourists. Cheap rockets for space travel will have been developed，permitting long journeys throughout the solar system(太阳系). When that time comes，people will be taking holidays in space and visiting other planets. Great progress will have been made in medicine，too. Perhaps a cure will have been discovered for the most terrible of all diseases—cancer. Pollution is a problem we must solve. In a hundred years’time it will have been controlled.
All the world will have been developed — even 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 as well.
We will have used up most of earth’s land to build our cities， so floating cities will have been built. The Japanese already have plans for cities of this kind. And there will be cities under the sea. The first of these will have been completed.

London Underground
    The world’s first subway was built in London in 1863. At the time，the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages to get through. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to go to and from work， they would relocate their homes outside of the city. This would help ease(减轻) the pressure of too many people living in the poor parts of London. From these problems，the idea of the London Underground，the first subway system，was born.
    The plans for building the Underground met with several problems and delays， but the fast track was finally opened in January 1863. A steam train pulled the cars along the fast underground track which was 6 kilometers (3.7 miles) long. About 30，000 people got on the subway the first day. Riders were treated to comfortable seats (standing up while the train was moving was not allowed),and pleasant decorations inside each of the cars. However，the smoke from the engine soon filled the air in the tunnels with ash and soot(煤灰)，as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems，riding in the Underground did catch on. It carried  9 million riders in its first year.
