听力原文： Robert Edwards became blind in an car accident nine years ago. He was also partially deaf because of old age. Last week, he was taking a walk near his home when a thunderstorm approached. He hid under a tree and was struck by lightning. He was knocked to the ground and woke up some twenty minutes later, lying face down in bed. A short time later, he awoke; his legs were unfeeling and he was trembling, but, when he opened his eyes, he could see the clock across the room fading in and out in front of him. When his wife entered, he saw her for the first time in nine years. Doctors confirm the flash of lightning, but they are unable to explain the occurrence. The only possible explanation offered by one doctor was that, since Edwards lost his sight as a result of injury in a terrible accident, perhaps the only way it could be restored was by another injury.
