Section C 26 Advertisement can be thought of “as the means of making known in order to buy or sell goods or services“. Advertisement aims to increase peoples awareness an

The press offers a fairly cheap method, and magazines【 B2】 _reach special sections of the market. The cinema and【 B3】 _radio are useful for local market. Television, although more expensive, can be ve

Other ways of increasing consumer interest are through exhibitions and trade fairs as well as direct mail advertisement. There can be no【 B6】 _that the growth in advertisement is one of the most striking features
19、 of the western world in this century. Many businesses such as those handling frozen foods, liquor, tobacco and medicines have been built up【 B7】 _by advertisement. We might ask whether the cost of advertisement is paid for by the producer or by the customer. Since advertisement forms part of the co
20、st of production, which has to【 B8】 _the selling price, it is clear that it is the customer who pays for advertisement. However, if large-scale advertisement leads to increased demand, production costs are reduced, and the customer pays less. It is difficult to measure exactly the influence of adver
21、tisement on sales. When the market is growing, advertisement helps to increase demand. When the market is【 B9】 _, advertisement may prevent a bigger fall in sales than would occur without its support. What is clear is that businesses would not pay large sums for advertisement if they【 B10】 _its valu

I do not just mean gallons of water leaking from the pipes of my local water authority. I【 C1】 _tumbling waterfalls, f
23、oaming fountains and rushing streams with no point except to look good. So I have taken the【 C2】 _and gone to see the most famous water garden in Europe, the Villa dEste at Tivoli near Rome. When I told a【 C3】 _garden designer that I was going to the villa, he looked【 C4】_pained and told me that I r
24、eally should not bother. It was the sort of place, he thought, that was only popular with tours and coaches. I think he was mixing the villa with all those later copies called Tivoli Gardens, which make a much feebler use of water. In fact, the villa gardens are magnificent. They are even more【 C5】
25、_than when I last visited because they have been given a new life as part of Italys millennium(千禧年 )clean-up. In Britain, we got the【 C6】_Millennium Dome. In Italy they got clean buildings and garden fountains that really work. At the Villa dEste, more of them work at one time than I have seen in th

It resulted from the ambitions of a frustrated【 C8】 _for the papacy(罗马教皇职位 )and an untied attitude to the surrounding landscape, ruining anything in its

Actually it is a world monument that has deserved the【 C10】_of millions of visitors since it was completed. A)defied I

AEver since humans ea
29、rly ancestors first peeled shellfish along the southern coast of France 300,000 years ago, food has been the measure of the bounty(物产 )of the sea. These days, however, the notion of that bounty is expanding. Increasingly, it includes genetic building blocks contained in unique deep-sea creatures tha
30、t thrive under conditions once thought impossible for sustaining life. BBut as biotech companies begin to eye these organisms as a potential source of raw material for medicines and other products, calls are emerging for rules of the road to help ensure that the benefits of deep-sea gene prospecting
31、 are shared globally. Admittedly, most biotech and pharmaceutical companies are not yet rushing to hydrothermal(热液的 )vents, sea mounts, and other unique habitats to dig up organisms and figure out if they can be useful. The vast majority of marine bio-prospecting these days is done in shallower wate
32、rs within a countrys 200-mile limit, notes Sam Johnston, a senior research fellow at the Institute of Advanced Studies of United Nations University, based in Japan. CYet as marine scientists learn more about deep-sea habitats and the variety of organisms that live there, commercial interest is likel
33、y to grow. Moving now on some sort of regulatory scheme is a chance to get ahead of the curve, he says. And it would provide an antidote(解毒剂 )to regulatory uncertainty, which is preventing some companies and research groups from pursuing deep-sea bio-prospecting more vigorously. “We have a window of
34、 opportunity,“ says Dr. Johnston, who coauthored a UN report on the issue that was released last week. “The issues are much easier to deal with before commercial interests become heavily vested(既得的 )in the hunt for deep-sea genetic material.“ DThe issue carries echoes of debates over mining minerals
35、, such as manganese(a kind of mineral), in the deep ocean, which formed part of the background for the international Law of the Sea Treaty in 1982. Costly venture EYet today, manganese remains on the seafloor. In the push to negotiate the treaty “people forgot the economics of it. Its unbelievably e
36、xpensive to do deep-sea mining,“ says Andy Solow, director of the Marine Policy Center at the Woods Hole Oceanographic Institution in Woods Hole, Mass. “That is also true of bio-prospecting in the deep ocean its expensive.“ He also says, “The real prospects for bio-prospecting in the deep oceans, es
37、pecially in the near-and-medium-term, are fairly low.“ FBut it differs from mining in significant ways. If the targets are deep-sea bacteria, for example, they can be cultured and preserved once theyve been hauled to the surface. Exploiting the genetic information they contain doesnt require a conti
38、nuous presence on the seafloor. Oceans cover 70 percent of the planets surface at an average depth of slightly more than two miles. Little wonder that the oceans contain the majority of Earths biodiversity. Thus the appeal of the deep can be powerful, even for scientists whose main interest is in un
39、derstanding how these creatures and their ecosystems work. Their efforts can yield insights into the difficulties associated with bio-prospecting on the seafloor. GDoug Bartlett, for example, focuses his work on bacteria from ocean trenches long, deep gashes in the undersea crust. “The physical rule
40、s that govern existence are so different compared with what humans experience,“ says the researcher at Scripps Institution of Oceanography in La Jolla, Calif. “Temperatures are close to freezing, the pressure is enormous, they live in perpetual darkness, and food is so variable that their physical b
41、asics are controlled in very different ways.“ HStudying these creatures is a costly proposition. Ship time runs roughly $10,000 a day. Once bacteria are brought to the surface, they must be prepared quickly for culture before they begin to die. Once the preparations are complete, the Petri dishes(皮氏
42、培养皿 )they now inhabit must be placed in steel-and-titanium vessels that can reproduce the temperatures and pressures the bacteria normally experience as high as 7.5 tons per square inch. And it takes time to process and analyze samples. “If all youre doing is going out to collect DNA, youll really b
43、e limited in what youll discover,“ he says. More-targeted searches might yield better results, he says. But the investment of time and money remains large. IIndeed, even in-shore prospecting can tax wallets and local sea life. The UN study notes that a compound derived from sea sponges, known as spo
44、ngistatin(软海绵素 ), is used as an anticancer agent. During research, it took 2.5 tons of sea sponges to isolate less than 1 ounce of the compound. Still, the study notes that the number of potentially useful compounds for every compound tested is higher for marine organisms than for land-based organis
45、ms. This has led to global sales for marine biotech products worth roughly $ 100 billion a year. Deep-sea ethics JOver time, as technology improves for sampling and analyzing deep-sea organisms, interest in hunting for genes in trenches, along hydrothermal vents, along the slopes of sea mounts, and
46、at cold seeps(地下水 )on the seafloor is expected to grow. KSome analysts point out that the Law of the Sea Treaty draws a distinction between mineral resources under the sea and biological resources namely fish. Mineral resources outside a countrys exclusive economic zone belong to everybody. Internat
47、ional panels were set up to ensure that a portion of the proceeds from mining would be channeled into aid or other help for developing countries. Fish hooked on the high seas, however, belonged to whoever caught them. Genetic material falls into the realm of biology and so should be available to who
48、ever can haul it up and turn it into something useful. LYet the UNs Dr. Johnston notes that in addition to costs, the lack of clear rules governing deep-sea bio-prospecting is preventing many companies from taking the plunge delaying the potential benefits experts envision for building new marine bi
49、ological compounds into medicine, farming, industry, environmental clean-up, and cosmetics. Such research is important to undertake, he says. Beyond these stumbling blocks lie what Johnston and his coauthor Charlotte Salpin see as overriding ethical and environmental issues. MBiological materials under the high seas are “not just open-and-free access. They are actually the resources of the world community“,
