[填空题]Foreign Exchange Trading
Without foreign exchange trading, international trade itself could not exist. In former times trade was based on bartering—goods were exchanged for other goods.

Unfortunately，the real world of economics outpaced this system．The U.S.dollar suffered from inflation(its value relative to the goods it could purchase decreased)，while other currencies became more valuable and more stable．Finally，in 1971，the U.S.took away
