二、英翻中：（15 分）Tariffs have a long history and were once an important source of fiscal revenue for many countries. Tariffs generally refer to the taxes imposed by governments on goods when they are imported. The purpose of a tariff can be to increase national fiscal revenue or to protect specific domestic industries. When a country’s domestic market is subject to dumping of certain foreign goods, a government may temporarily legislate to impose anti-dumping duties specifically to protect its own industries. This is a mixed tariff that both increases national revenue and protects its own economy.
