听力题 One Saturday morning a careless motorist threw a lighted cigarette out of his car ten miles west of town. The forest at the side of the road was dry because there was no rain for many days. Within a few minutes the trees were on fire. A truck driver saw the fire when he was on his way to the town. As soon as he reached the town, he told the police about the fire. Soon firemen were hurrying westwards. When they reached the fire, they saw it was very big. It could not spread to the north because of a lake or the south because of a wide river. But a west wind was carrying the fire towards the town and the firemen could not stop it. When they realized this, one of the firemen sent a message back to the town by radio. The chief fire officer and hundreds of people hurried to a place about half a mile west of the town. There they used dynamite to blow down the trees and clear a wide path or break through the forest. When the fire reached the break, it began to die down, because there was nothing left to burn. The wind blew some sparks across the break, but the firemen soon put out the fire and saved the town.
