Full steam ahead.

Nowadays, there are so many means of transport, from bicycles and buses to sports cars and jet airplanes, that travellers arc spoilt for choice. In fact, 1)..........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.

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".

Fortunately, a small number of there are being used today to offer river cruises so 9)..........people can get a feel of what it's like to travel by steamboat.
