答案　B

解析　推理判断题。由文章最后一句"More and more people will try to improve their lives through educational opportunities outside of their homeland-an idea usually uncommon in developing countries."可知，现在越来越多的人通过本国之外的教育机会来改善他们的生活，这一点在过去的发展中国家是不常见的。由此可以推断出，过去发展中国家的人们很少想到通过接受国外的教育来改变自己的命运。

China，endowed with rich agricultural resources，has a long history of farming.The traditional farming practice with intensive(精细的) cultivation(耕作) as its essence is one of the most important achievements of the human civilization.The development of agriculture and rural areas in China is faced with many problems.The Chinese government has made a number of important policies and measures to cause a faster growth of farmers' income and narrow the ever­enlarging income gap between rural and urban residents as soon as possible mainly through finishing a strategy of balanced social and economic development.We'll give top priority in all work to solving problems facing agriculture，farmers and rural areas，focusing on the following seven aspects.

Firstly we'll promote faster increase of farmers' income.Secondly we'll protect and increase the overall capacity of grain production.Thirdly we will continue to promote strategic restructuring of agriculture.Fourthly we'll actively promote progress in agro­science and enhance research work of agricultural high­tech and key research programs，and increase its reserve level.Fifthly we'll further open agriculture to the outside world and actively develop agricultural trade with other countries.Sixthly we'll speed up the transfer of rural labors and develop rural secondary and tertiary(第三的) industries.Seventhly we'll continue to deepen rural reforms.

Priorities(优先权) will be placed on reform of rural land system，tax and administrative charges，grain distribution system and rural financial system.However，agricultural development has difficult tasks and a long way to go.The road ahead is by no means smooth.Nevertheless，China's agriculture will give full play to its advantages，overcome any difficulties，enter a new stage of development and match towards a brighter new future in the new century!
