Questions
1. What is the difference between a bus and a coach
The main difference between the two is that a bus often travels on a fixed route while a coach is the means of transport for people who travel to a relatively faraway place. Both of them look very similar, but in most cases a coach is designed for long-distance travellers, so you won’t be surprised to find a coach equipped with air conditioning, seats with cushions and DVD players. In contrast, a bus appears very plain.
There are two reasons. First, air travel is quicker. Businessmen who value time regularly travel by aeroplane 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.
2. Why do you think people would choose to travel by aeroplane rather than by ship
Different types of transport can meet different customers’ needs. Each type of transport has its own strengths and limitations.
3. Why do you think we need all these different types of transport

Transport and Weather
Weather conditions have a strong influence on transport. It is very important that drivers are aware of weather conditions such as wind, rain or a typhoon. Ship captains need to know about wave conditions. Airplane pilots want to know about the condition of the atmosphere. Automobile drivers and railroad engineers have to know if rain or snow is going to fall. Without correct, timely weather information, transportation equipment cannot be safely operated. That's why operators of such equipment and passengers may pay very close attention to weather reports.
