单选题When an invention is made, the inventor has three possible courses of action open to him. he can give the invention to the world by publishing it, keep the idea secret, or patent it. 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 that period terminates. Only in the most exceptional circumstances is the lifespan of a patent extended to alter this normal process of events. The longest extension ever granted was to Georges 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 colour TV to receive and thus 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 repatent. 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 19th 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.

单选题Many phrases used to describe monetary policy, such as "steering the economy to a soft landing" or "a touch on the brakes", makes it sound like a precise science. Nothing could be further from the truth. The relation between interest rates and inflation is uncertain. And there are long, variable lags before policy changes have any effect on the economy. Hence the analogy that likes the conduct of monetary policy to driving a car with a blackened windscreen, a cracked rearview mirror and a faulty steering wheel. Given all these disadvantages, central bankers seem to have had much to boast about. Average inflation in the big seven industrial economies fell to a mere 2.3% last year, close to its lowest level in 30 years, before rising slightly to 2.5% this July. This is a long way below the double-dig- it rates which many countries experienced in the 1970s and early 1980s. It is also less than most forecasters has predicted. In late 1994 the panel of economists which The Economist polls each month said that America"s inflation rate would average 3.5% in 1995. In fact, it fell to 2.6% in August, and is expected to average only about 3% for the year as a whole. In Britain and Japan inflation is running half a percentage point below the rate predicted at the end of last year. This is no flash in the pan; over the past few years, inflation has been continually lower than expected in Britain and America. Economists have been particularly surprised by favourable inflation figures in Britain and the United States, since conventional measures suggest that both economies, and especially that of America, have little productive slack. America"s capacity utilisation, for example, hit historically high levels earlier this year, and its jobless rate (5.6% in August) has fallen below most estimates of the natural rate of unemployment—the rate below which inflation has taken off in the past. Why has inflation proved so mild? The most thrilling explanation is, unfortunately, a little defective. Some economists argue that powerful structural changes in the world have up-ended the old economic models which were based upon the historical link between growth and inflation.
