Andy rode slowly on his way to school, day-dreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.

He rode along until a strange sound drew him to the present. He came to a stop and looked up to the sky. What he saw frightened him. A huge group of bees filled the sky like dark cloud and seemed to be heading angrily towards him.

With no time to waste Andy sped off in the opposite direction, riding quickly without knowing how to escape the group. With a rapidly beating heart and his legs pumping quickly, he sped down the rough road. As the bees came closer, his fear increased. Andy knew that he was sensitive(敏感的) to bee stings (蜇). Last time a sting had put him in hospital—and that was only one bee sting! He had been forced to stay in bed for two whole days. Suddenly, his father’s words came to him. “When you are in a dangerous situation, don’t panic. Stay calm, use your brain and think your ways out of it. ”

On a nearby hill, he could see smoke waving slowly from the chimney(烟囱) of the Nelson family home. “Bees don’t like smoke,” he thought. “They couldn’t get into the house.” Andy raced towards the Nelson house, but the bees were gaining around. Andy knew he could not reach the house in time. He guessed that the bees would catch up with him soon.

Suddenly, out of the corner of his eyes, he saw a small pond used by Mr. Nelson to water his vegetable garden. Off his bike and into the cool water he jumped, disappearing below the surface and away from the bees. After holding his breath for as long as he could, Andy came up for air and noticed the bees have gone. Pulling himself out of the water, he walked up the hill and rang the doorbell. Mr. Nelson took him inside and rang his mother.

“You’ll really need that fishing break to help you recover(恢复),” laughed his mother. “Thank goodness you didn’t panic!” But Andy did not hear her. He was dreaming once again of the fish he would catch tomorrow.
