Mr. Wang and his wife went to the supermarket the last Sunday. They arrived home very lately. On the way upstairs, Mrs. Wang said, “Listen! I can hear someone talk in kitchen.” Then they went downstairs and quiet stood there outside the room. “Yes, you are right,” said Mr. Wang. “There are two boy. They are talking!” Then they call out. “Who’ s there?” And no one answered. Mr. Wang opened the door quickly and turned on the light. The room is empty. When they saw the radio, they laughed. The radio was still on. “Oh, dear,” he said, “I forgot to turn it off when they left.”
