Then the barter（物物交换）system was replaced by coins, which still had real value since they were pieces of rare metal. Coins were followed by fiat money, paper notes that have value only because everyone agrees to accept them.Today electronic monetary（货币）systems are gradually being introduced that will transform （转换）money into even less tangible forms, redu cing it to a series of “bits and bytes”, or units of computerized information, going between machines at the speed of light. Already, electronic fund transfer allows money to be instantly sent and received by different banks, companies, and countries through computers and telecommunications（无线通讯）devices.6.Which of the following would be the best title for the passage?A.International Banking PoliciesB.The History of Monetary ExchangeC.The Development of Paper CurrenciesD.Current Problems in the Economy【批阅】回答正确！【答案】B7.According to passage, which of the following was the earliest kind of exchange of wealth?A.Bartered goodsB.Fiat money（纸币）C.Coin currencyD.Intangible forms【批阅】回答正确！【答案】D8.The author mentions food, tools and precious metals and stones together because they are all _________.eful itemsB.articles of valueC.difficult things to obtainD.material objects【批阅】回答错误！9.According to the passage, coins once had real value as currency because they _________.A.represented a great improvement over barterB.permitted easy transportation of wealthC.were made of precious metalsD.could become collectors’ items【批阅】回答正确！【答案】C10.Which of the following statements about computerized monetary systems is NOT supported by the passage?A.They promote international trade.B.They allow very rapid money transfer.C.They are still limited to small transactions（交易）.D.They are dependent on good telecommunications systems.【批阅】回答正确！【答案】CPassage 2In the old days, divers（潜水员）used to go down into the sea looking for ships that had sunk, because they hoped to find gold and jewels.
