［误］ Farmers live in the countries.

［正］

Farmers live in the country.

［析］ 但作为"国家"讲时则可有单、复数形式，例如：Japan is an Asian country. Japan, China, and India are Asian countries.另外，country一般指的是地理概念上的国家，如：New Zealand is an agricultural country. 而nation多指民族组成的国家，如：The Chinese nation(中华民族)。state多侧重于政权方面的区域、国家范围，如：the state farm(国营农场)
