Lesson 2 Economy of the USA. The Numerals. The United States has been the world's leading industrial nation since early in the 20th century. Until the second half of the 19 century, agriculture remained the dominant US economic activity. After the Civil War, great advances were made in the production of basic industrial goods. By World War 1, exports of manufactured goods had become more important than the export of raw materials, as manufacturing grew, agriculture became increasingly mechanized and efficient, employing fewer workers. The most important development in the economy since World War 11 has been the tremendous growth of service industries, such as government services, professional services, trade and financial activities. Today, service industries are the most important sector of the economy, employing almost three quarters of the workforce. Manufacturing employs proximately 17 per cent of the labour force and agriculture less than 3 per cent of the workers. Beginning in the 1930s, the government of the United States played an increasingly active role in the economy. Even though the US economy in the 1990s was based on free enterprise, the government regulated business in various ways. Some government regulations were drawn up to protect consumers from unsafe products and workers from from unsafe working conditions, others were designed to reduce environmental pollution. The US economy consists of three main sectors - the primary, secondary and tertiary. Primary economic activities are those directly involving the natural environment, including agriculture, forestry, fishing and mining and usually contribute about 4 per cent of the yearly GDP. Secondary economic activities involve processing or combining materials into new products and include manufacturing and construction, this sector accounts for approximately 23 per cent of the GDP. Tertiary economic activities involve the output of services rather than goods. Examples of tertiary activities include wholesale and retail trade, banking, government and transport. The tertiary is the most important sector by far and accounts for almost 73 per cent of the annual GDP. Answer the questions: 1. When according to the author, the US became a world's leading industrial nation? 2. What tendency took place by the end of the Civil War? 3. What is said in the text about the development of the service industry? 4. What is said about the size of the manufacturing sector of the economy? 5. What role does the government play in the modern economy of the USA? 6. What was the US GNP in 1993? 7. What according to the text, are the three major sectors of American economy? 8. What are the examples of tertiary activities? Помогите пожалуйста ответить на вопросы по тексту
