阅读理解 Was he dreaming? David Ewart saw a red ball of fire. He shot out of a deep sleep and heard his ten-year-old daughter, Heather, screaming. Ewart jumped out of bed on the second floor of  his home. Downstairs he heard loud popping noises, glass bulbs, furniture, appliances exploding as fire consumed them. Three hundred and fifty people, including friends and family members, had attended Ewart's annual Christmas party at his home in Valencia, California. David was a giver. They all enjoyed themselves. After the party, he and his 77-year-old mother, Esther, put out the candles all but one, missed and left burning on a holiday paper tablecloth. Now, as Ewart started down the hall to alert his parents and three children, he said a silent prayer: God, if it is your will, save us. The heat was hellish(地狱般的). But then he felt a hand on his shoulder and something that was not quite a voice guiding him, giving him the direction: the bedroom window. He kicked out the window screen and told Heather to jump onto the patio(院子) cover, crawl to the edge and drop to the ground, the feet below. Next he headed for his two sons, Jonathan, 13, and Michael, 15, who were screaming with pain. David led Jonathan to the window. He returned for Michael, who was now helping his grandparents, trapped in their room behind a jammed door. Michael threw himself against it and finally burst through. David guided his mother, then Michael, to safety. Only his father remained. The 81-year-old's face was badly burned. He lost his footing and fell. David took his hand and helped him to the window. Too weak to hold on, his father rolled off the patio cover to the ground. Finally,David escaped. Second later, the second floor exploded, yet all the while, he felt he was being led, under protection. The family survived and firefighters said they were mystified(迷惑) as to how the family survived. David Ewart was not.. 1. Why did the fire take place?
