The building crane, which has become the most striking feature of the urban landscape in Switzerland, is beginning to alter the mountain landscape as well. Districts of the Swiss Alps, which up to now have consisted of only a few disconnected small communities content with selling cheese and milk, perhaps a little lumber and seed potatoes, are today becoming parts of planned, developing regions. The new highway, the new skylift, the new multi-nationally-owned hotel will diversify the economy and raise the standard of living in the mountain areas, or so many Swiss regional planners and government officials hope.The mountainous area of Switzerland, which accounts for nearly two-thirds of the total area of the country and only 12% of the total population, has always been the problem area. According to the last census in 1970, 750,000 people lived in the Swiss mountains. Compared with the rest of the country, incomes are lower, services are fewer, employment opportunities are more limited and populations are decreasing. In fact, in only one respect do mountain districts come out ahead. They have more farmers, which many people do not consider to be an advantage. 17% of the Swiss mountain population works in primary occupations, in contrast to only 8% of the total population of the country.The mountain farmers are a special breed of men. They work at least twelve hours a day in topographical and weather conditions which kill most crops and which only a few animals will tolerate. About half of them work at some other jobs as well, leaving ’their wives and children to do the bulk of the farm work. In the Rhone Valley in the canton of Valais in south-western Swizerland nearly four-fifths of the farmers commute daily from their mountain farms to the large factories in the valley. In other parts of Switzerland this pattern of life is not as common, but almost everywhere n. on-farm wintertime employment is the rule.With all the difficulties inherent in working in the Swiss mountains, why should anyone resist any extension of the mountain economy The answer, as Andress Werthemann, editor of the Swiss mountain agriculture magazine Alpwirtschafiliche Monatsblatter states, is that "when tourism becomes too massive, farming disappears". And basically there are three reasons why Switzerland needs its mountain farmers: they contribute to the food supply, they preserve the landscape, and they represent the Switzerland of nostalgia and holiday dreams.But in the real world, and especially in highly industrialized Switzerland where mountain farmers are aware of the "benefits" of city living, is it possible to maintain mountain agriculture and still solve the problems of mountain communities The Swiss government has come to the conclusion that other kinds of employment in addition to farming must be emphasized. Yet whether it is possible to create other jobs that will not completely destroy agriculture is unknown. The majority of farmers in the Rhone Valley ().

A. do the great part of the farm work in the valley
B. work in factories in the valley and travel from their farms in the mountains daily
C. work long hours a day
D. work at some other jobs besides farm work

A granted patent is the result of a bargain struck between an inventor and the state, by which the inventor gets a limited period of monopoly and publishes full details of his invention to the public after the period terminates.Only in the most exceptional circumstances is the life-span of a patent extended to alter this normal process of events.The longest extension ever granted was to George Valensi. His 1939 patent for color TV receiver circuitry was extended until 1971 because for most of the patent’s normal life there was no hope of reward for’ the invention.Because a patent remains permanently public after it has terminated, the shelves of the library attached to the patent office contain details of literally millions of ideas that are free for anyone to use and, if older than half a century, sometimes even re-patent. Indeed, patent experts often advise anyone wishing to avoid the high cost of conducting a search through live patents that the one sure way of avoiding violation of any other inventor’s right is to plagiarize a dead patent. Likewise, because publication of an idea in any other form permanently invalidates further patents on that idea, it is traditionally safe to take ideas from other areas of print. Much modern technological advance is based on these presumptions of legal security.Anyone closely involved in patents and inventions soon learns that most "new" ideas are, in fact, as old as the hills. It is their reduction to commercial practice, either through necessity or dedication, or through the availability of new technology, that makes news and money. The basic patent for the theory of magnetic recording dates back to 1886. Many of the original ideas behind television originate from the late 18th and early 20th century. Even the Volkswagen rear engine car was anticipated by a 1904 patent for a cart with the horse at the rear. George Valensi's patent lasted until 1971 because().

A. there were not enough TV stations to provide color programs
B. the color TV receiver was not available until that time
C. nobody would offer any reward for his patent prior to that time
D. his patent could not be put to use for an unusually long time
