Tom likes eating fish very much. He often buys fish in the shop and takes them home. One day, his wife(妻子) saw the fish and thought," Good! Now, I can ask my friends to have lunch and we can eat the fish. They like fish very much. "
When Tom came home from work in the evening, the fish was not there and his wife said, "Oh, your cat eats it. "And then she gave him some bread for his supper. Tom was angry(生气). He took the cat and his wife to a shop near his house and weighed(称) the cat. Then he turned to his wife and said, "My fish weighs one kilo(公斤). The cat weighs one kilo, too. My cat is here, you see, then, where is my fish?"
