Achievements have been made in the development of transport: Before the Industrial Revolution, animals such as horses and mules were used for public transport.

After the Industrial Revolution, because of Watt’s invention, steam trains soon played an important role in public transport. Buses and ships then became popular as well. Underground trains also became popular as the traffic became too crowded in cities.

There are now many means of transport from which people can choose. The speed is also much faster.

Work in groups to discuss. 1. What do you know about high-speed trains? High-speed trains can run very fast — at the speed of over 200 kilometres per hour. The speed of the train which runs from Beijing to

Tianjin reaches more than 300 kilometres per hour. Though a high- speed train is not as fast as an airplane, it is quite convenient for people to use to travel from one city to another nearby city. A high- speed train produces almost no pollution because it uses electricity.

2. Why would many people choose to travel by airplane rather than by ship? There are two reasons. First, air travel is quicker. Businessmen who value time regularly travel by airplane because of its speed.

Second, travelling by plane is more comfortable than by ship. With the improvement of technology, many airline companies offer excellent services at a reasonable price.

Different means of transport can meet different customers’ needs. Each mean of transport has its own strengths and limitations. 3. Why do we need all these different means of transport?
