单选题{{B}}Part B{{/B}} In the following article some paragraphs have been removed. For questions 66—70, choose the most suitable paragraph from the lists A—F to fit into each of the numbered gaps. There is one paragraph which does not fit in any of the gaps. Mark your answers on ANSWER SHEET 1. The ten-year battle over baby-milk that has pitted the champions of breast feeding against more than a dozen powerful multinational companies will reach its climax next week. At a meeting of the World Health Organization, 157 governments will vote on a code backed by consumer groups, churches and health experts — which would prohibit companies from all direct advertising and promotion of baby milk, from issuing samples and gifts to health workers, from using company "nurses", and even from paying sales commission to their staff. Almost certainly, the code will be passed. The result, its backers hope, will reverse the trend away from breastfeeding — especially in the Third World, where it is reckoned that more than a million lives could be saved each year if mothers abandoned artificial substitutes. 66.____________ In the United States, they argue that a ban on advertising would be contrary to constitutional freedoms — which, they say, includes the "freedom of Commercial speech." But even the companies no longer dispute the medical facts. Infant formula — a powered mixture based on cow's milk — is indisputably inferior to human milk because it lacks the natural antibodies, which protect babies against many common diseases including measles and diarrheas. In Third World countries, where mothers without refrigerators or detergents are diluting the mixture with polluted water, baby milk is a risk to children's health. A leading world paediatrician, Dr. Derrick Jeliffe, estimates that about 10 million cases a year of infants malnutriton and infectious diseases can be attributed to improper bottle-feeding. The companies emphasize that baby milk has an important role for working mothers and for women who cannot breastfeed. 67.____________ The poorest are in any case those least able to afford commercial substitutes. For a typical Third World agricultural worker, feeding one child on baby milk requires between 20 and 50 percent of the family budget. The result, often, is that older children go hungry. For the companies, baby milk is big business. The Third World market, growing at 15 percent a year, is already worth about 700 million — double the sales in the US. For the poor countries the trade is a multimillion dollar drain on their foreign exchange, and the avoidable child diseases caused by baby milk increase the strains on the health services. 68.____________ They have used aggressive marketing throughout the Third World — creating, their critics claim, a "need" which in all but a handful of cases does not exist. Advertising is the central target of the Geneva code. It makes no attempt to ban the sale or use of baby milk, or to resist sales to chemists or government-controlled outlets. The companies say the code is therefore unnecessary, because in October 1979 their umbrella organization, the International Council for Food Industries, agreed on a voluntary code which included the adandonment of direct advertising in developing countries. Since that date, however, the International Baby Food Action Network claims to have documented more than 1,000 violations of the voluntary code. 69.____________ Some companies, including Cow and the US could still vote against the code. Above all, the companies fear that the code will apply equally to the lucrative Western market. This is far from certain because the WHO bowing to pressures from some industrialised countries and milk-surplus producers in the Common Market, has presented its code as a recommendation, not a legally-binding regulation. 70. ____________ [A] This means that it is up to individual governments whether or not to apply it. [B] The companies disclaim responsibilities for the misuse of their products and for their use in dangerous conditions. [C] The companies are lobbying strongly against the code because it would virtually eliminate legitimate competition and because it pays no attenion to different countries' conditions. [D] But detailed and international restrictions cannot be the answer. National measures based on a set of internationally agreed general principles is the realistic approach and one which has already been shown to work in countries like Malaysia and Singapore. [E] Besides, medical sales workers still do the rounds of hospitals and clinics, leaving piles of booklets, posters and free samples. [F] Yet recent research shows that only a minute percentage of mothers are unable to feed their babies, even among the badly under-nourished.

单选题 Shortages of flu vaccine are nothing new in America, but this year' s is a whopper. Until last week, it appeared that 100 million Americans would have access to flu shots this fall. Then British authorities, concerned about quality-control problems at a production plant in Liverpool, barred all further shipments by the Chiron Corp. Overnight, the U.S. vaccine supply dwindled by nearly half and federal health officials found themselves making an unusual plea. Instead of beseeching us all to get vaccinated, they' re now urging most healthy people between the ages of 2 and 64 not to. "This reemphasizes the fragility of our vaccine supply," says Dr. Martin Myers of the National Network for Immunization Information, "and the lack of redundancy in our system." Why is such a basic health service so easily knocked out? Mainly because private companies have had little incentive to pursue it. To create a single dose of flu vaccine, a manufacturer has to grow live virus in a 2-week-old fertilized chicken egg, then crack the egg, harvest the virus and extract the proteins used to provoke an immune response. Profit margins are narrow, demand is fickle and, because each year's flu virus is different, any leftover vaccine goes to waste. As a result, the United States now has only two major suppliers ( Chiron and Aventis Pasteur)--and when one of them runs into trouble, there isn' t much the other can do about it. "A vaccine maker can't just call up and order 40 million more fertilized eggs," says Manon Cox, of Connecticut-based Protein Sciences Corp. "There's a whole industry that's scheduled to produce a certain number of eggs at a certain time. " Sleeker technologies are now in the works, and experts are hoping that this year's fiasco will speed the pace of innovation. The main challenge is to shift production from eggs into cell cultures--a medium already used to make most other vaccines. Flu vaccines are harder than most to produce this way, but several biotech companies are now pursuing this strategy, and one culture-based product (Solvay Pharmaceuticals' Invivac) has been cleared for marketing in Europe. For Americans, the immediate challenge is to make the most of a limited supply. The government estimates that 95 million people still qualify for shots under the voluntary restrictions announced last week. That' s nearly twice the number of doses that clinics will have on hand, but only 60 million Americans seek out shots in a normal year. In fact, many experts are hoping the shortage will serve as an awareness campaign--encouraging the people who really need a flu shot to get one.

单选题Koalas, an Australian tree-climbing animal, are very particular about what they eat, devoting themselves entirely to a diet of the leaves of eucalyptus trees. But there are problems associated with an exclusive diet of leaves, especially if, like the koala, you happen to be a relatively small animal. One of these problems is that the leaves of trees are rich in fibre, and so resist digestion. Eucalyptus leaves are worse than most, for they contain large amounts of lignin, the indigestible, woody material found in the cell walls of many plants. But there is another drawback for the koala. The ratio of an animal's gut volume to its energy requirements depends on body mass; the smaller it is, the lower the ratio. So tiny leaf-eaters are likely to have difficulty processing sufficient quantities of their poor-quality food to meet their metabolic needs. S. J. Cork and T. J. Dawson of the University of New South Wales and I. D. Hume of the University of New England have made a study of the koala's digestion. They have identified three major factors that allow koalas to exploit its fibre-laden diet. In the first place, the koala has a discerning digestive system; like the rabbit, it can regulate the passage of food through its gut in a way that discriminates between particles of different sizes. The alimentary canal retains and solutes smaller, more digestible particles, while expelling unwanted, coarser matter. This is probably a space-saving exercise; it has the effect of increasing the rate at which raw material can be fed into the system. The second factor behind the koala's success is that it has a low overall requirement for metabolic energy, compared to other Australian animals of similar size. So it saves on its fuel needs. In this respect, the koala is not dissimilar to another slow-moving, leaf eating mammal, the three-toed sloth. Thirdly, eucalyptus leaves have hidden qualities. Despite the large quantity of lignin, such leaves are rich in digestible energy -especially in the form of fatty substances. Not all such resources are available to the koala's metabolic machinery; essential oils are passed out, for example. But some fatty substances are available, as are sugar and starch. It is these compounds that satisfy the bulk of the koala's energy needs. Surprisingly, constituents of the eucalyptus's cell walls, such as cellulose, are less important. Some cellulose is digested, but the koala's accomplishments in this field do not rival those of other animals that reshow.

单选题Cyberspace, data superhighway, multi media — for those who have seen the future, the linking of computers, television and telephones will change our lives for ever. Yet for all the talk of a forthcoming technological Utopia, little attention has been given to the implications of these developments for the poor. As with all new high technology, while the West concerns itself with the "how", the question of "for whom" is put aside once again. Economists are only now realizing the full extent to which the communications revolution has affected the world economy. Information technology allows the extension of trade across geographical and industrial boundaries, and transnational corporations take full advantage of it. Terms of trade, exchange and interest rates and money movements are more important than the production of goods. The electronic economy made possible by information technology allows the haves to increase their control on global markets — with destructive impact on the have-nots. For them the result is instability. Developing countries which rely on the production of a small range of goods for export are made to feel like small parts in the international economic machine. As "futures" are traded on computer screens, developing countries simply have less and less control of their destinies. So what are the options for regaining control? One alternative is for developing countries to buy in the latest computers and telecommunications themselves — so-called " development communications" modernization. Yet this leads to long-term dependency and perhaps permanent constraints on developing countries'' economies. Communications technology is generally exported from the U. S. , Europe or Japan; the patents, skills and ability to manufacture remain in the hands of a few industrialized countries. It is also expensive, and imported products and services must therefore be bought on credit — credit usually provided by the very countries whose companies stand to gain. Furthermore, when new technology is introduced there is often too low a level of expertise to exploit it for native development. This means that while local elites, foreign communities and subsidiaries of transnational corporations may benefit, those whose lives depend on access to the information are denied it.
