A foolish dog
Long long ago，a dog had a large piece of meat in his mouth. When he was walking across a small bridge，he looked down and saw himself in the water. He thought it was another dog. That dog also had a large piece of meat in his mouth. He said to himself，“I want to get his meat. Then I can have two pieces of meat.” He opened his mouth to bark（吠叫）at the dog in the water，and his meat fell（掉落）into the water at once.
