Tom got a fishing rod （鱼竿） for his birthday. He decided to go ice fishing to make good use of his gift. Early the next morning, he took all things for fishing to the ice. When he arrived, he dug a large hole in the ice and put the rod in. Suddenly he heard a voice, "There are no fish in it. " So he moved to another place and dug another hole, but then the same voice spoke again and told him there were no fish in it. So he moved again, and the voice told him there were no fish a third time. Tom looked up in surprise and saw an angry man looking down at him. "How do you know there are no fish？" asked Tom. The man said coldly, "Well, first of all, this is a hockey rink （冰球场）, and second of all, you must pay for those holes. "
