Means of communication
People use various means of communication to go from one place to another. In the old days
people had to travel several days, weeks and months to get to the place they needed. They either
went on foot, by coaches driven by horses or on horseback or by boats and ships. Then trains, trams,
cars, buses, airplanes, underground and other means appeared.
Many people like to travel by air as it is the fastest way of travelling. A lot of people like to
travel by train because they can look at passing villages, forests and fields through windows. Some
people like to travel by car. There they can go as slowly or as fast as they like. They can slop when
and where they want.
People who live in big cities use various means of communication to get from one place to
another. Do you know what means of communication Londoners use? Londoners use the
underground railway. They call it 'the tube'. London's underground is the oldest in the world. It was
opened in 1863.Londoners use buses. The first bus route was opened in London in 1904. Today
there are hundreds of routes there. The interesting thing is that some of the routes are the same as
many years ago.
London's buses are double-decked buses. Londoners do not use trams, though London was the
first city where trams appeared. And now it is one of the biggest cities in the world where there are
no trams. The last tram left the streets of London many years ago. Londoners use cars. You can see
a lot of cars in London streets. When Londoners leave the town, they use trains, ships or airplanes.
