[听力原文]The Interstate Highway System In the United States it is possible to drive more than four thousand kilometers from the east coast on the Atlantic Ocean to the west coast on the Pacific Ocean. You can also drive more than two thousand kilometers from near the Canadian border south to the Mexican border. You can drive these distances on wide, safe roads that have no traffic signals or stop signs. In fact, if you did not have to stop for gasoline or sleep, you could drive almost anywhere in the United States without stopping at all. This is possible because of the Interstate Highway system. This system has almost seventy thousand kilometers of roads. It crosses more than fifty-five thousand bridges and can be found in forty-nine of America’s fifty states. The Interstate Highway system is usually two roads, one in each direction, separated by an area that is planted with grass and trees. Each road holds two lines of cars that can travel at speeds between one hundred and one hundred twenty kilometers an hour. The Interstate Highway system has been an important part of the nation’s economic growth during the past forty years. Experts believe that trucks using the system carry about seventy-five percent of all products that are sold. Jobs and new businesses have been created near the busy Interstate Highways all across the United States. These include hotels, motels, eating places, gasoline stations and shopping centers.
