Прочитайте текст и выполните задания к нему.WHAT IS INTERNATIONAL TRADE?Switzerland, they can use the money they earn to importSwiss chocolate — or to pay for Kuwaiti oil or a vacation in Hawaii. The basic idea ofinternational trade and investment is simple: each country produces goods or services that can beeither consumed at home or exported to other countries.The main difference between domestic trade and international trade is the use of foreigncurrencies to pay for the goods and services crossing international borders. Although global tradeis often added up in U.S. dollars, the trading itself involves various currencies. Japanesevideocassette recorder is paid for in German marks in Berlin, and German cars are paid for inU.S. dollars in Boston. Indian tea, Brazilian coffee, and American films are sold around theworld in currencies as diverse as Turkish liras and Mexican pesos.Whenever a country imports or exports goods and services, there is a resulting flow of funds:money returns to the exporting nation, and money flows out of the importing nation. Trade andinvestment is a two-way street that, with a minimum of trade barriers, usually makes everyonebetter off.In a interlinked global economy, consumers are given the opportunity to buy the best products atthe best prices. By opening up markets, a government allows its citizens to produce and exportthose things they are best at and to import the rest, choosing from whatever the world has tooffer.Some trade barriers will always exist as long as any two countries have different sets of laws.However, when a country decides to protect its economy by erecting artificial trade barriers, theresult is often damaging to everyone, including those people whose barriers were meant toprotect.The Great Depression of the 1930s, for example, spread around the world when the United Statesdecided to erect trade barriers to protect local producers. As other countries retaliated, tradeplumpered, jobs were lost, and the world entered into a long period of economic decline.
