英语翻译
For example,the United States is a major consumer of coffee,yet it does not have the climate to grow any or its own.Consequently,the United States must import coffee from countries (such as Brazil,Colombia and Guatemala) that grow coffee efficiently.On the other hand,the United States has large industrial plants capable of producing a variety of goods,such as chemicals and airplanes,which can be sold to nations that need them.If nations traded item for item,such as one automobile for 10,000 bags of coffee,foreign trade would be extremely cumbersome and restrictive.So instead of batter,which is trade of goods without an exchange of money,the United State receives money in payment for what it sells.It pays for Brazilian coffee with dollars,which Brazil can then use to buy wool from Australia,which in turn can buy textiles Great Britain,which can then buy tobacco from the United State.
Third,one nation can sell some items at a lower cost than other countries.Japan has been able to export large quantities of radios and television sets because it can produce them more efficiently than other countries.It is cheaper for the United States to buy these from Japan than to produce them domestically.According to economic theory,Japan should produce and export those items from which it derives a comparative advantage.It should also buy and import what it needs from those countries that have a comparative advantage in the desired items.
Finally,foreign trade takes place because of innovation or style.Even though the United States produces more automobiles than any other country,it still imports large numbers of autos from Germany,Japan and Sweden,primarily because there is a market for them in the United States.
For most nations,exports and imports are the most important international activity.When nations export more than they import,they are said to have a favorable balance of trade.When they import more than they export,an unfavorable balance of trade exists.Nations try to maintain a favorable balance of trade,which assures them of the means to buy necessary imports.

例如,美国是咖啡的主要消费国,但是它的气候并不适合自己种咖啡.其结果是,美国必须从盛产咖啡的国家（比如,巴西,哥伦比亚,危地马拉）进口.从另一方面说,美国有很庞大的工业工厂生产各式各样的商品,比如化学药品,飞机,这些都可以卖给需要它们的国家.如果国与国之间直接使用物品交易,如一辆车交换10000袋咖啡,对外贸易将变得十分地笨重和受限制.因此,美国接受使用钱来支付它所卖的东西,而不是采用不使用货币的方式.美国支付美元买巴西人的咖啡,巴西使用这些钱买澳大利亚的羊毛,澳大利亚可以买英国的纺织品,英国可以从美国买烟草.
第三,一个国家可以以更低的价格出售某些物品.日本能够出口大量的收音机和电视机,因为与其它国家相比,它的生产效率更高.美国直接从日本买这些比在本国生产还更便宜.根据经济理论,出于比较的优势,日本应该生产并出口这些物品.它也可以从那些拥有比较优势的国家买入和进口它所需要的其它物品.
最后,对外贸易也因为创新或流行样式而发生.即使美国比其它国家生产更多的汽车,它仍需要从德国、日本、瑞典进口大量的汽车,主要因为美国有它们的市场.
对大多数国家来说,进出口是最重要的国际活动.当一些国家出口大于进口,称它们有贸易顺差.当它们的进口大于出口,则存在贸易逆差.国家总是尝试保持贸易顺差,以确保它们购买必需的进口物品的财富.
