Section C 26 It is only right that the stars should be paid in this way

15、. Dont the top men in industry earn【 B1】 _salaries for the services they perform to their companies and their countries? Pop stars earn vast sums in foreign【 B2】 _ often more than large industrial concerns - and the taxman can only【 B3】 _their massive annual contributions to the finance. So who woul

16、d envy them their rewards? Its all very well for people in【 B4】 _jobs to moan about the successes and rewards of others. People who make【 B5】 _remarks should remember that the most famous stars represent only the tip of the iceberg. For every famous star, there are hundreds of others struggling to e

17、arn a living. A man working in a steady job and【 B6】_a pension at the end of it has no right to expect very high rewards. He has chosen security and peace of mind, so there will always be【 B7】 _what he can earn. But a man who attempts to become a star is taking enormous risk. He knows at the outset

18、that only a【 B8】 _of competitors ever get to the very top. He knows years of concentrated effort may【 B9】 _complete failure. But he knows, too, that the rewards for success are very high indeed: they are the rewards for the huge risks involved and if he achieves them, he has certainly earned them. T

However, nearly all require some break in ones career in order to attend sc

20、hool full time. Part-time education, that is, attending school at night or for one weekend a month, tends to drag the process out over time and puts the【 C1】 _of a degree program out of reach of many people. Additionally, such programs require a【 C2】 _time commitment which can also impact negatively

21、 on ones career and family time. Of the many approaches to teaching and learning, however, perhaps the most flexible and accommodating is that called distance learning. Distance learning is an educational method, which【 C3】 _the students the flexibility to study at his or her own pace to achieve the

22、 academic goals, which are so【 C4】 _in todays world. The time required to study may be set aside at the students【 C5】 _with due regard to all lifes other requirements. Additionally, the student may enroll in distance learning courses from【 C6】 _any place in the world, while continuing to pursue thei

23、r chosen career. Good distance learning programs are characterized by the inclusion of a subject evaluation tool with every subject. This【 C7】 _the requirement for a student to travel away from home to take a test. Another characteristic of a good distance-learning program is the【 C8】 _of the distan

24、ce-learning course with the same subject materials as those students taking the course on the home campus. The resultant diploma or degree should also be the same whether distance learning or on-campus study is【 C9】 _. The【 C10】 _of the professor/student relationship is another characteristic of a g

25、ood distance-learning program. In the final analysis, a good distance learning program has a place not only for the individual students but also the corporation or business that wants to work in partnership with their employees for the educational benefit, professional development, and business grow

27、ection B 46 Does the World Face a Future of Water Wars? AThroughout history, people have fought bitter wars over political ideology, national sovereignty and religious expression. How much more intense will these conflicts be when people fight over the Earths most indispensable resource water? We ma

28、y find out in the not-too-distant future if projections about the availability of water in the Middle East and other regions prove correct. BLess than three percent of the planets stock is freshwater, and almost two-thirds of this amount is trapped in ice caps, glaciers, and underground aquifers(含水层

29、 )too deep or too remote to access. In her book, Pillars of Sand Can the Irrigation Miracle Last?, Sandra Postel outlines three forces that drive tension and conflict over freshwater: CUsing up the water “resource pie“. In India, the worlds second-most-populous nation, with over 1 billion inhabitant

30、s, the rate of groundwater withdrawal is twice that of recharge, a deficit higher than in any other country. DAlthough water is a renewable resource, it is not an expanding one. The freshwater available today for more than 6 billion people is no greater than it was 2,000 years ago, when global popul

31、ation was approximately 200 million.(The current U.S. population is 287 million.) EGlobal agriculture accounts for about 70% of all freshwater use. In five of the worlds most water-stressed, contentious areas the Aral Sea region, the Ganges, the Jordan, the Nile and the Tigris-Euphrates population i

32、ncreases of up to 75% are projected by 2025. With the fastest rate of growth in the world, the population of the Palestinian territory will more than double over the next generation. FMost experts agree that, because of geography, population pressures and politics, water wars are most likely to erup

33、t in the Middle East, a region where the amount of available freshwater per capita will decrease by about 50% over the next generation. Canadian writer Marq de Villiers notes that “it is now widely accepted that the 1967 Arab-Israeli War had its roots in water politics as much as it did in national

34、territorialism.“ Speaking in 1996 of regional and global tensions arising from environmental damage, the U.S. Secretary of State Warren Christopher stated that “nowhere is this more evident than in the valleys of the Middle East, where the struggle for water has a direct impact on security and stabi

35、lity.“ GPostel estimates that the almost 2.4 billion world population increase projected over the next 35 years will require the water equivalent of 20 Nile Rivers or 97 Colorado Rivers. These astonishing numbers begin to make sense upon consideration that the production of one ton each of grain and

36、 rice require approximately 1,000 and 3,000 tons of water, respectively. It is hardly surprising that, of the 34 countries classified as “water-stressed,“ 32 are net grain importers. HIn his award-winning book, Environment, Scarcity, and Violence, Thomas Homer-Dixon states that water is the resource

37、 most likely to trigger interstate warfare, a sentiment echoed by Jacques Leslie: “Oil belongs to whoever owns the land above it; water complicates ownership.“ IAlmost 40% of the worlds population resides in the 214 river basins that flow through two or more countries. All but three percent of Egypt

38、s freshwater comes from the Nile, a river that originates in Ethiopia and makes its way through Sudan before reaching the ancient land of the pharaohs. To date, only the poverty in Ethiopia and Sudan has prevented a water war. What will happen when these two nations commence water-intensive drives t

39、oward modernization as well as strive to satisfy the thirst of a projected 139 million more people(the equivalent of four Californias)by mid century? Canadian water and security analyst Steve Lonegran of British Columbias Victoria University has stated: “I dont doubt that if Ethiopia starts building

40、 water projects that restrict the flow of the Nile, Egypt will bomb them.“ JDe Villiers reminds us that two-thirds of Israels water comes from the Golan Heights and the West Bank, territories it gained via military conquest. Noting the restrictions imposed on groundwater withdrawals from the West Ba

41、nk by Israel, Homer-Dixon states: “These restrictions have been far more severe for Palestinians than for Israeli settlers. They have contributed to the rapid decline in Palestinian agriculture in the region, to the dependence of Palestinians on day laborers within Israel, and, ultimately, to rising

42、 frustrations in the Palestinian community.“ While numerous political, economic, and ideological factors also must be taken into account, he concludes that “water scarcity“ has been a factor in at least one uprising in the West Bank and Gaza territories. KAs citizens of an advanced industrial societ

43、y, we tend to look for a technological “fix“ to problems, and the escalating(逐步增长的 )freshwater shortfall is no exception. Cleansing seawater of its salt and mineral content would provide a never-ending supply of potable water. The basic desalinization(脱盐 )process, as de Villiers notes, is simple hig

44、h school chemistry: Water is heated, evaporated to remove salt and other dissolved minerals, and then cooled back to water. However, this distillation method is full of difficulties. Approximately 60% of the 11,000 desalinization plants that collectively account for less than one percent of the worl

45、ds freshwater needs are in the Middle East, where fuel is affordable and abundant. Even if the cost and availability of fuel were not problematic, adding plenty of additional greenhouse gases to the atmosphere would make global warming even worse and increase the evaporation of groundwater. Reverse

46、osmosis pumping sea water at high pressure through a series of membranes(薄膜 )that trap salt and other minerals is less energy-intensive than distillation, but removes almost everything from seawater, leaving the remaining freshwater susceptible to “fouling“. LThe problem as well is how purified wate

47、r can be cost-effectively transported hundreds of miles inland to agriculture regions. How will desalinization help poor and landlocked Mali, Niger and Chad? The management and costs of desalinization indicate that this process will supply no more than a fraction of humanitys freshwater needs in the

48、 coming years. MThe United Nations estimates that there are currently more “water refugees than war refugees, and all indications are that the destabilizing consequences of the water-driven migration of people will increase. Poor people forced to leave their homeland are rarely welcomed by equally p

49、overty-stricken individuals who resent the added competition for scarce resources. NAlthough it is unlikely that water issues alone will lead to a major war, shortages of this most essential resource will elevate tension in parts of the planet already plagued by deep hatred and suspicion. This, in turn, could increase the chances that some other issue or incident will trigger a conflict. OThomas Osborne, a
