阅读理解。 At a few minutes past five. Dave noted that the blanket of darkness was lifting. He was just able to make out the heavier masses that ually appeared as the familiar trees that lined the road at the base of the hill. The upper reaches of the sky showed lighter shades of gray. Dave got out of bed quietly and dressed quickly. He mixed a spoonful of instant chocolate into a glass of cold water, and his impatience forced him to finish the drink in gulps. As he walked down toward the lake. Dave paused to reach for the fishing pole and gear box on the bench where he had left them the night before. By the time where he reached the small boat, a thick white mist (雾气) had spread over the suce of the water. He stepped into the boat, sat down, and rowed out of the weed beds that lined the edge of the shore. The outer fringe (边缘) of the lake disappeared as the boat moved forward noiselessly. All he could see was the enveloping whiteness. He could not tell where the boat and the surrounding air met the suce of the lake. Dave rowed steadily ahead, relying of a mental picture of the surroundings. Then the mist began to rise, slowly it soon rested inches above the still suce of the lake. The heavy silence was now being broken by the fish breaking through the suce as they leaped out of the water for low-flying insects. The magic time had arrived. Dave raised his pole. Davn was broken.
