A few years ago, Ed Jones was shopping at a second-hand store. He (look) for something that might be valuable. If he found something valuable, he would buy it cheaply and then resell it. Suddenly, something caught is eye-—a large cardboard map.
The map (cover)with dust, so M. Jones wiped it clean. Under the dust was a color map of Paris. It looked old. On the back of the map: ＄3. Mr. Jones was quite certain that the map was worth more than three dollars, so he bought it.
The next day, Mr. Jones took the map to a geography professor. After looking at the map for a few minutes, the professor became very excited. "I've read about his map!" he exclaimed. Then he told Mr. Jones what he (know).
In 1671, the king of France, Louis XIV, asked a cartographer （制图者）（make）a map of Paris. The cartographer worked on the map for four years. The map was beautiful—it was not just a map, but a work of art as well. The cartographer carefully colored one of the copies, using blue for rivers, green for trees, and brown for buildings. The professor said that one black and white copy of the map was in the British Museum in London, and another was in the Bibliotheque Nationale in Paris. "I think, "the professor said, "you(find) the color copy of the map — in a second-hand store in the US!"
The professor suggested that Mr Jones take the map to New York City. Experts there could tell Mr Jones if the professor was right.
Mr Jones took the map to New York City. The New York experts told him that the map was extremely valuable. "How much do you think it's worth?" Mr. Jones asked the experts. Millions, "they replied. "It's impossible to say exactly how much the map (be) worth It's worth whatever someone is willing to pay for it"
Soon Mr. Jones discovered how much people were willing to pay for the map. The most recent offer even reached 19.5 million dollars.
Mr. Jones hasn't decided whether he (sell) his three-dollar map at that price or wait for a higher offer. He (think) it over.
