Question

英语翻译
Most economists from the time of Adam Smith have favored free international trade and have opposed tariffs and quotas.A tariff is a tax on an import and a quota is a limitation on the number of units that may be imported.On the other hand,a great many people over the years have argued for some form of restriction on international trade,for "protection" from foreign producers.Politicians have at times been persuaded by economists and others who have been in favor of free trade,and have been persuaded at other times by those arguing for restrictions.The United States and other Western nations have had sizable fluctuations in the average level of tariffs.
