A naughty dog went into the back of a butcher’s shop(肉铺). He saw a big meaty bone. He decided to take it with him. 60 He ran out of the shop, carrying the bone in his mouth, and rushed into the forest. 61 He looked down from the bridge and he saw another dog! The dog was carrying a big meaty bone. He thought, “That bone is much better than mine. It’s got more meat on it, and I think it’s longer too! 62 I’m going to take that bone!” So saying, he jumped off the bridge. He opened his mouth to bite(咬) the other dog, letting go of his bone. But as soon as he hit the water, the other dog disappeared. And his bone sank into the river. 63 .“You saw another dog and another bone, but they were just reflections! Now you’ve lost your bone, and got soaking (浸湿) wet too!”
