Transportation and Communication Guide

Look at the pairs of pictures, talk about them in groups making comparisions.

Answer - The train is depicted in the first image while the bullet train is in the second. With the aid of the bullet train, we are able to travel at an extremely high speed, but it is also expensive. Traditional train travel is inexpensive but slow. Similarly, the bus is shown in the final image while the car is shown in the third. In a car, we can travel easily, quickly, and at our own pace, but owning and maintaining a car is expensive. Contrarily, although taking the bus is less expensive, we cannot travel at our own convenience and will. On the bus, we must adhere to the predetermined and fixed route (and on the train as well).

Pilots are increasingly accustomed to learning to fly with innovations like ground proximity warning systems, automatic pilot, and GPS as technology has advanced with the launching of satellites and the development of lighter materials in the space age. Greater speed and flight stability have been made possible by winglets and sleeker designs, and the needle-nosed supersonic Concorde has appeared to hint at a future dominated by turbojets. Consequently, the airplanes have made much more progress at the present.
