单选题 Once upon a time there lived a fisherman in a village near the sea. One day the fisherman set out in a small boat. After he had got to a good place for fishing, he threw a long rope, then the rope became very heavy. He thought it seemed too heavy to be a fish, and began to draw in the rope.
When the hooks(鱼钩)came out of the water, he was surprised , for the hooks were holding some golden chains (链子). When he pulled them, more and more golden chains came out. Soon there was a long pile of golden chains in his boat.
"I shall be very rich, "he said to himself. "I can sell the chains for a lot of money. With the money I shall buy a new boat and some new nets. I shall build a house. I shall be the richest man in the world."
He went on drawing in more golden chains. But he felt so pleased that he did not notice what was happening to his boat. It began to sink(下沉). As he was pulling the golden chains, the boat sank into the sea. He lost not only all the golden chains but also his boat and his life.
