sports cars and jet airplanes, that travellers arc spoilt for choice. In fact, many of us don't even think about how we travel; plane or train, it doesn't matter. Because, at the end of the day, it's just about getting from one place to the other.

There are, however, some means of transport that have made an impression on people and have taken their place in history. One means of transport that truly won the hearts of many Americans was the river steamboat. A steamboat, as its name indicates, is a boat that is powered by steam. The steam rotates a paddlewheel or propeller that in turn causes the boat to move forward.

In the 18th century, there were many attempts to build better vessels, but it wasn't until 1807 that the first successful steamboat, The Clermont, made a commercial voyage. These riverboats became popular in the next few years and were used to transport passengers and merchandise on the major rivers of America. The Mississippi River was especially known for its riverboats, and Mark Twain celebrated three steamboats in his book "Life on the Mississippi".

Steamboats have now disappeared from most American rivers, but they have become a symbol of the Mississippi River. Many people think of these boats when they hear the name Mississippi. Fortunately, a small number of them are being used today to offer river cruises so some people can get a feel of what it's like to travel by steamboat.

these institutions did not exist, many companies would not at all be able to go international. The U.S. government created the Export-Import Bank(Eximbank) in order to reduce unemployment in the country. Eximbank makes loans to U.S. exportrers and foreign buyers of U.S. imports if private financing is not available. A firm can also buy insurance from the Foreign Credit Insurance Association (FCIA) to cover political risk (such as expropriation and loss due to war).The exporter can also buy insurance coverage on credit sales to foreign customer.

construct wondeful cathedrals - the best example of Gothic architecture. During the 14 century guns appeared in europe. From the 15 to the 17 century the period of Renaissanse spread in New World was discovered and explored.The printed books helped the development of European cultural life.The Renaissanse saw a new interest in technology, and the new technology led to new problem. One problem was that shipbuilding and iron industry needed a lot of wood and Europe soon lost its forests. Another problems was the need in more powerful engines. the 18 century in Europe was the time of the Industrial revolution, the time when technology developed very fast.In 1712 Thomas Newcomen, an Englishman,invented the steam engine.In the 1760, James Watt improved the Newcomen engine, which opened the way to constructing steamboat and locomotives in the early 19 century. The Industrial Revolution gave rise to the engineering profession. More and more universities began to train engineers. During the 19 and 20 centuries peoples lives have greatly changed thanks to science and technology. Achievements in transportation, comemunications and use of energy have had a great influence on the modern society. Medical knowledge has given people longer and healthier lives. Computers are giving us new opportunities at work and at home. Now people have better living standards and much more free time. On the other hand, a lot of people may argue that such great technological achievements do not come without a price. New technology has led to creating weapons of mass destruction, new communication technology and spread of information have brought with them less privacy, the great use and abuse of natural resources is now damaging the environment, the great intensity of human life leads to stresses and makes us question the advantages of high technology.
