| Ann's grandpa was very rich and he had some shops. The old man began to learn drawing when he was sixty, and he loved it very much. For twelve years he drew a lot and there were many pictures in his workroom. He was pleased with them and kept them well. One day, the old man was ill. He had to stay in hospital. Before he died (死), he said to Ann, "I want to give my pictures to a school as gifts. Then the students can remember me forever. But I don't know which school I'm going to give them to. Can you help me?" "Well," said the little girl, "you'd better give them to a blind (瞎的) school." |
