听力原文: It's very necessary for Canada to set up effective transportation system because of its enormous size with its sparsely populated distribution. It is also very difficult to make transportation construction on the surface of the country due to its harsh long winter and its mountainous terrain. It's really amazing for this country to set up a transcontinental railroad since last century. Much of the country's freight is transported by Canadian National Railway and Canadian Pacific Railway. But nowadays fewer and fewer people travel by train.
Water transportation was very important before railway construction. Although passenger travel by water is less important than before, waterways remain important for cargo transporting. Waterways include lakes, rivers and sea coastlines.
Because of the increasing number of automobiles, Canada's road transportation develops very quickly. In 1991, road length has been more than 849,400 kilometers. Road system is becoming more and more important. Trucks carry nearly half of the total freight transported in Canada.
With the development of transportation, airplanes became another necessary vehicle since airplanes could be the only access to some areas of the far northern region.
Canadian transportation system develops very quickly with the increasingly advanced science and technology. The aim of the transportation is to use substitute fuels and to produce more efficient transportation facilities.
