40、 could tie them together.篇章导读：本文是一篇说明文，文章主要按照时间顺序讲述了中国和世界上其他国家货币发展的历史。1F根据设空前一句“people used many different kinds of things for buying and selling”及设空后一句“This exchange of goods and services for other goods and services is called bartering (物物交换)”可知，此处主要讲的是“物物交换”，F选项中“buying a chicken might cost sever

41、al potatoes”是“物物交换”的一个例子，符合上下文语境，故选F项。2E由前文可知，本文第一段讲的是“物物交换”；由设空下一句“In 1200 BC, people in China began to use shells (贝壳) as money. Usually the shells used as money were very small.”可知，第二段讲的是“贝壳作为货币的使用”，故此空的作用是承上启下。E项中的“such exchanges”与第一段句末的“This exchange”相呼应，选项中的“However”以及“impractical”表明物物交换有局限性，所

42、以出现更加方便携带的贝壳货币，符合上下文语境，故选E项。3C根据设空前一句“many other countries around the world began to do the same”可知，许多其他国家也开始这样做了。to do the same指的就是“也开始用贝壳买卖”，故C项(他们也使用小贝壳作为货币进行买卖)符合上下文语境，故选C项。4G根据设空前一句“It wasnt long before the Chinese made round coins out of metal.”可知，中国出现了金属的圆形钱币；根据设空下一句“By 500 BC, metal coins ha

43、d begun to appear in countries like Persia and Greece, and later in the Roman Empire.”可知，到公元前500年这种金属钱币开始在其他国家出现。故G项(这种首次出现的钱币中经常有孔以便人们把它们串起来。)符合上下文语境，故选G项。5D根据空前句“the first paper banknotes were produced by the Chinese people”可知，此处讲到了纸币的出现，故D项(很多年后纸币才出现在欧洲。)符合上下文语境，故选D项。语法填空Two weeks after the popul
