B
When we think of money, we think of coins and paper bills. That is what money is today. But in the past people used many things instead of money. Some countries used cows. Some countries used salt, tea or stones. Today there are still some places in the world that do not use paper money. One place is the Island of Yap(雅浦岛）in the Pacific Ocean.
On the Island of Yap, people use the heaviest money in the world—Yap stones. They are round, white stones with a hole in the middle. The Yap stones are not from the island. The Yap men have to go to the island four hundred miles away to get them. Big stones can be four meters high—as big as two tall men. Some stones are as big as a dinner plate. Rich people do not carry the Yap stones. Servants follow the rich. Each servant carries a stone on the pole(杆子）over his shoulder. Today the people on the island use paper money for everyday shopping. But for other things they still prefer stones.
