1. Modern people use various means of transportation to get 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 so on. Then trams, cars, buses, planes,
underground and other means appeared.
2. Many people like to travel by plane as it is the fastest way of traveling. A lot of

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 stop when and where they want.

has 277 stations and it is 244 miles long.

cities in the world where no trams have been used for many years. Londoners
