C. Three years ago, Mr Johnson retired(退休). He returned to his hometown with his wife. Bad luck! The old woman died five months ago and now he had to live in the small town alone. His son asked him to live with them in the city, but he refused. He hated the noisy life there. He had some new friends and thought he enjoyed himself. So the young man bought a nice vat(缸) with about fifty goldfishes (金鱼) in it. They could never make any noise in the night and his father could have a good sleep.
　　Mr Johnson liked the goldfishes and took good care of them. He bought some books and did all what’s said in them. He often told his friends about his goldfishes and they went to visit them. He was very happy.
　　A few days later, the old man looked worried. A cat of his neighbour’s stole(偷) his goldfishes at night. He tried to catch it, but he couldn’t. He had to sleep near the vat. It made him very tired. So the angry old man went to a shop and said, “Excuse me, sir. Where can I buy a shark(鲨鱼), please?”
　　“Oh?” the man in the shop said in surprise. “What do you have it for?”
　　“I want to teach the cat a lesson(教训)!”
