Traditional markets still function in many parts of the world. Even in the United Sales, during summer months there are farmers' markets where direct selling and buying take place between producers and consumers. Most service industries still operate at this market level. Manufacturing industries and most agricultural enterprises are more distant from the consumer. Their products pass through several hands—truckers, warehouse wholesalers, and retailers before reaching the final consumer. Products, or commodities are usually divided into two types: consumer and industrial. Consumer goods are those that are sold to final users, the customers. These goods include food, clothing, automobiles, television sets, appliances, and all those things people go to stores to purchase. Industrial goods are those that are sold to companies or other businesses for use in manufacturing or other purposes. Automobile makers buy many of the parts used to assemble cars. A tire manufacturer buys rubber, synthetic or otherwise, with which to make tires. Eventually these materials will end up in the hands of final users: the owners of the cars. The nature of industrial goods depends on the nature of the goods to be made for final users. The price of industrial goods and raw materials will influence the price of final goods, those that the consumer buys.

单选题The UK government has some way to go in building trust in its handling of genetic modification in agriculture. Lessons learnt in Britain ( and no doubt elsewhere ) from the BSE (疯牛病) crisis were evident in the UK government's announcements last week of plans to change the way it regulates genetically modified crops. Out goes any lingering assumption that the technology is inherently safe, and in comes a new requirement for industry to demonstrate practically that its products will not have adverse ecological effects. In a welcome move, a new steering group of scientists will be able to commission research it considers necessary on the ecological impacts of genetically modified crops. The government, in turn, promises not to allow the commercialization of any crop until the scientists are reasonably satisfied that it is safe to proceed. The government's attempts to build public trust in its scientific advice, and to include public views in its policy decisions, however, leave some questions open. It has chosen to set up a new forum of 'environmental stakeholders' whose view would contribute to decisions about genetic modification in agriculture. This forum, spanning the spectrum of interests and opinion, will need to make constructive suggestions, and avoid well-trodden, predictable and ultimately time wasting disputes between industry and environmentalism. The government is already poised to embark on a survey of the public--as opposed to environmentalist--perception of the biosciences. Ministers would be wise to wait for its outcome before putting more flesh on the stakeholders' forum. But the latter should eventually be encouraged to make constructive contributions to the research agenda. In doing so, it will not only address public concerns about the risks of genetically modified crops, but should also help rebuild public trust in the application of science to foods. Here again, however, the government will need to ensure that the chance to influence research is not used as an unyielding instrument of obstruction by fundamentalist opponents of genetic modification. Scientists on the whole are supportive of the changes, particularly the decision to authorize research trials on a commercial scale. They rightly seek better security arrangements following recent incidents of crop destruction. They should cautiously welcome, rather than oppose, increased public awareness and scrutiny of their activities while being themselves watchful over the details of the processes the government is putting in place.

单选题The explosion of a star is an awesome event. The most violent of these cataclysms, which produce supernovae, probably destroys a star completely. Within our galaxy of roughly 100 billion stars the last supernova was observed in 1604. Much smaller explosions, however, occur quite frequently, giving rise to what astronomers call novae and dwarf novae. On the order of 25 novae occur in our galaxy every year, but only two or three are near enough to be observed. About 100 dwarf novae are known altogether. If the exploding star is in a nearby part of the galaxy, it may create a "new star" that was not previously visible to the naked eye. The last new star of this sort that could be observed clearly from the Northern Hemisphere appeared in 1946. In these smaller explosions the star loses only a minute fraction of its mass and survives to explode again. Astrophysicists are fairly well satisfied that they can account for the explosions of supernovae. The novae and dwarf novae have presented more of a puzzle. I shall describe recent investigations that have provided important new information about these two classes of exploding star. The picture that emerges is quite astonishing. It appears that every dwarf nova--and perhaps every nova--is a member of a pair of stars. The two stars are so close together that they revolve around a point that lies barely outside the surface of the larger star. As a result the period of rotation is usually only a few hours and their velocities range upward to within a two-hundredth the speed of light, Astronomers use the term "cataclysmic variable" to embrace the three general classes of exploding star: dwarf novae, novae, and supernovae. A cataclysmic variable is defined as a star that suddenly and unpredictably increases in brightness by a factor of at least 10. Dwarf novae are stars that increase in brightness by factor of 10 to 100 within a period of several hours and decline to their former brightness in two or three days. In this period they emit some 1038 to 1039 ergs of energy. At maximum brilliance a dwarf nova shines about as intensely as our sun, previously it had been only about a hundredth as bright. The number of outbursts ranges anywhere from 3 to 30 a year, but for any one star the intervals have a fairly constant value. Moreover, the maximum bright ness from outburst to outburst is the same within a factor of two for a given star. The dwarf novae are often referred to, after their prototypes, as U Geminornm or SS Cygni stars. (The stars of each constellation are designated by letters or numbers.) A subgroup of dwarf novae, called Z Camelopardalis stars, do not always descend to minimum bright ness between outbursts but may stay at some intermediate level for several months.
