Unit 2 working the land导读：民以食为天，粮食是人类立足之本。中国泱泱农业大国，你了解粮食的重要性吗？ The development of agriculture and the balance between food and population are Chinas fundamental economic problems. The classical histories praise emperors for devotion to agriculture and much of Chinas modern history is the story of the unfolding struggle to feed a peasant population, which has been growing steadily. Today, although agriculture accounts for only a quarter of the Gross National Product, it is still the main determinant of the standard of living and the principal occupation of at least 70 percent of population. Agriculture also determines the progress of industry because industry needs both agricultural raw materials and food for its work force. The failure of agriculture to supply raw materials and food halted and later reversed the industrial progress of the 1950s. After 1960 new emphasis was placed on agriculture, and the slogan “Agriculture is the foundation of the economy” has remained a central Chinese economic policy ever since. In addition to the direct links between agriculture and industry, there is an indirect link due to therelationship between agriculture and foreign trade. Many of Chinas exports are either agricultural raw materials or consumer goods based on them. Flourishing agriculture, therefore, promotes exports. 请根据语义及提示写出单词 1.
