1.EThe need to feed a growing population is putting much pressure on the world’s supply of water. With 97% of the world’s water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage（短缺）seems strange to someone fortunate enough to live in a high rainfull country, many of the world’s agricultural industries experience constant water shortages.Although dams can be built to store water for agricultural use in dry areas and dry seaons, the costs of water redistribution(重新分配)are very high. Notonly is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water many flow easily through pipes to fields,but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.This is particularly troubling ro countries with agricultural industries in areas dependent on irrigation（灌溉）. In Texas, farmers’ overuse of irrigation water be resulted in a 25% redcution of the water stores. In the Central Valley area of south eastern USA, a huge water engineering project provided water for farming in dry vallege, but much of the water use has been poorly managed.Saudi Arabia’s attempts to grow wheat in desert areas have been the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.72. From the first two paragraphs we learnt that _______.A.much of the world’s water is available for useB.people in high rainfll countries feel luckyC.the costs of water redistribution should be consideredD.water can be easily carried through pipes across the world

2.We drop a piece of metal into a jar full of water, the metal will float if it weighs less than______.A. an equal amount of silverB. an equal amount of goldC. all the water in the jar nowD. the water that leaves the jar

3.()must be familiar with these requirements of bilge water management, particularly those directly involved with such operations involving bilge water.A.All responsible personnelB.All the crew served in engine roomC.The masterD.The chief engineer

4.The text is mainly about .A.water supply and increasing populationB.water use management and agricultureC.water redistribution and wildlife protectionD.water shornages and environmental protection.

  • 第6题：

    问答题
    Research published in May 1998 by the Department of the Environment, Transport and the Regions (DETR) showed that reducing coastal and river pollution and ensuring a reliable water supply were among the top environmental priorities for the public.　　All discharges to water in the UK require the consent of the appropriate regulatory authority. In England and Wales the Environment Agency’s principal method of controlling water pollution is through the regulation of all effluent discharges, including sewage, into groundwater, and inland and coastal waters. The Agency maintains public registers containing information about water quality, discharge consents, authorizations and monitoring. Applicants for consents to discharge have the right of appeal if they are dissatisfied with the Agency’s decision; most of these appeals are dealt with by the Planning Inspectorate, an executive agency of the DETR. In Scotland control is the responsibility of the Scottish Environment Protection Agency (SEPA), and most appeals are dealt with by the Scottish Office. In Northern Ireland the Environment and Heritage Service is responsible for controlling water pollution.　　In 1997, there were 4,717 cases in England and Wales of discharges exceeding their consented limits, including a number of offences by water companies discharging insufficiently treated sewage. The majority of these breaches did not cause any significant environmental damage. However, the Environment Agency did bring 65 cases to court, of which 61 were successful, resulting in fines ranging from ￡ 440 to ￡ 12,000 and one prison sentence of two months. In Scotland, there were 2,734 pollution incidents in 1997; SEPA seeks prosecution in all significant cases.　　In 1997 and 1998, the Government introduced statutory Environmental Quality Standards (EQSs) for 33 substances in water. The new regulations give legal force for the first time to standards for some of the most dangerous pollutants found in the aquatic environment.　　In the UK, 96 percent of the population live in properties connected to a sewer, and sewage treatment works serve over 80 percent of the population. In England and Wales, the water industry is committed to an investment programme of some ￡ 11,000 million over ten years for improvements to water quality.  Progressively higher treatment standards for industrial waste effluents and new measures to combat pollution from agriculture are expected to bring further improvements in water quality. In Scotland, responsibility for the provision of all water and sewerage services lies with three Water and Sewerage Authorities, covering the north, east and west of the country.

    根据英国环境交通部于l998年5月公布的研究报告,减少沿海水域与河流的污染,保证供应安全用水,乃是广大公众在环保方面的当务之急。
    在英国,向水中倾倒任何东西,都需征得有关管理部门的同意。在英格兰和威尔士,环境署控制水污染的主要方法是监控一切流入地下水及内陆和沿海水域的废水,包括污水。环境署存有公开的记录,记载着水质、排放许可、授权单位、监督情况等事项。申请排放许可者如对环境署的决定不满,有权上诉,大多由计划督察团接受处理——督察团是部属的一个执行机构。在苏格兰,是由苏格兰环保署(SEPA)负责监控,上诉大多由驻苏格兰办事处接受处理。在北爱尔兰,水污染由环境与遗产局负责监控。
    1997年,在英格兰和威尔士共发生4717起超过许可限度的排污事件,其中有一些是水公司的过错,这些公司排放了未经充分处理的污水。这些违规行为绝大部分都没有对环境造成重大危害。然而,环境署也的确将65起违规事件送上法庭,其中61起环境署胜诉,判处的罚款自440镑至12000镑不等,还有一起判处败诉方两个月徒刑。在苏格兰,1997年共发生污染事件2734起;苏格兰环境保护署对情节严重者均予起诉。
    1997和1998年,政府实行法定环境质量标准,涉及水中33种物质。新规定使得关于在水中发现的几种最危险的污染物的标准第一次具有法律效力。
    在英国,96%人口的住宅与下水道系统相连,污水处理厂能为80%以上的人口服务。在英格兰和威尔士,水工业承诺在十年间将投资约110亿英镑,以改善水质。逐步提高工业废水处理标准,采取新措施以治理农业造成的污染,预计将会进一步提高水质。在苏格兰,三个给水排污管理局负责给水和排污的事宜,分管全国的北部、东部和西部地区。
