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

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

has 277 stations and it is 244 miles long.
