(2017·泰安中考)
Once a very rich man and his son collected valuable paintings of famous artists like Picasso, Van Gogh and Monet.
Later, the son left to join the army. After a few weeks, the old man received a letter saying his son had died while taking another soldier to a hospital. The old man became very lonely and sad.
One day, a soldier visited the old man and gave him a painting—it was a portrait(肖像) of his son. The painting of his son became the old man's most valuable item. He told his neighbours it was the greatest gift he had ever received. The following spring, the old man died.
