The World Is Getting Smaller and Smaller
With the development of science and technology, transport has hecome more and more sophisticated. The jet airliner, high-speed train, etc. were invented to meet the people's increasing need of speed. Nowadays people can travel from China to Peru within a day. Therefore, modem transport greatly facilitates people's travel from place to place. With the development of modem transport, contact between people and nations have become more frequent than ever before. In the old days only national leaders visited foreign countries. Nowadays mutual visits between nations are not limited to the national level, even grass-roots levels. Even individuals often go sightseeing abroad or go to visit their relatives abroad. It seems as if the whole world became a big family. The rapid development of modem transport may be partly responsible for these changes. However, in turn, the people's increasing need of transport promotes the development of transport.
