Text 3The farm is a major marketplace for millions of tons of synthetic fertilizers and pesticides (杀虫剂),and advanced machinery and the fuel required to run it. The modem superfarm, large and highly capitalized, is resource dependent compared with the diversified small farms that were once dominant. On diversified farms, major energy needs may be supplied by resident humans and animals. Soil fertility may be maintained by alternating cash crops and restorative crops, and also by returning animal manure (肥料) to the soil. This farming model of relatively self- sufficient agriculture, and the way of life associated with it, are still economically viable (可行 ), as demonstrated by prosperous Amish farmers and other practitioners of "alternative" agriculture. Particularly relevant to today’s mainstream agriculture are the energy-saving practices on large "organic" farms, which are thoroughly mechanized but which minimize the use of pesticides and synthetic fertilizers.By comparison, mainstream American agriculture has until lately been careless in its use of energy, water, and land. When fossil energy was cheap, applications of fertilizers and pesticides paid large dividends, so farmers were encouraged to use these products. Soon most farmers used too much fertilizer and pesticide. Farmers in dry regions enjoyed an era of cheap water, obtained from publicly subsidized irrigation systems or from pumping groundwater using, inexpensive energy. The soil too was expendable as demand grew f6r U.S. agricultural products.The period of extraordinary profligacy in the use of soil, water, and fossil fuels may well be at an end. The new structure of large farms is quite sensitive to cost factors. These adaptive farms, whose development was assisted by public tax, subsidy, and research policies, have access to capital, technologies, and management skills, enabling them to switch relatively quickly to resource-conserving practices -- for example, to a low-tillage system that requires less fuel, that shepherds soil moisture, and that may reduce soil erosion (侵蚀). It seems likely that federal programs that have enlarged our farms, therefore, have had a further result of creating the potential for a more conserving agriculture. With respect to energy use, for example, energy costs per unit of output are lower for large farms, mainly because these farms quickly economized on energy as costs rose. In the future, according to one authoritative assessment, "agricultural production is likely to use capital and land more intensively but energy, fertilizer and labor less intensively." The main difference between the modem superfarm and diversified farms is（）
Text 1Computer people talk a lot about the need for other people to become “computer literate”, in othe words, to learn to understand computers and what make them tick. But not all experts agree, however, that this is a good idea.One pioneer, in particular, who disagrees is David Tebbutt, the founder of Gomputer-town UK. Although many people see it’that way. He says that Computer-town UK was formed for computer, but David does not see it that way. He says that Computer-town UK was formed for just the opposite reason to bring computer to the people and make them “People-literate”.David first got the idea when he visited one of America’s best-known computer “guru”figures Bob Albrecht, who had started a project called Computer-town USA in the local library.Over here, in Britain, Computer-towns have taken off in a big way, and there are now about 40 scattered, over the country. David Tebbutt thinks they are most successful when tied to a computer club. He insists there is a vast and important difference between the two, although they complement each other. The clubs cater for the enthusiasts, with some computer knowledge already, who get together and eventually form an expert computer group. This frightens away non-experts, known as "grockles" (游客) who are happier going to Computer-towns where there are computers available for them to experiment on, with experts available to encourage them and answer any question; they are not told what to do, they find out.David Tebbut finds it interesting to see the two different approaches working side by side. The computer experts have to learn not to tell people about computers, but have to be able to explain the answers to the questions that people really want to know. People are not having to learn computer jargon (行话), but the experts are having to translate computer mysteries into easily understood terms; the computers are becoming "people--literate". About the computer towns and the computer clubs, David Tebutte thinks that（）
