　　【课文】

　　First listen and then answer the following question.

　　听录音，然后回答以下问题。

　　What is the most important factor, both in government or business, for keeping running costs low?

　　If a nation is essentially disunited, it is left to the government to hold it together. This increases the expense of government, and reduces correspondingly the amount of economic resources that could be used for developing the country. And it should not be forgotten how small those resources are in a poor and backward country. Where the cost of government is high, resources for development are correspondingly low.

　　This may be illustrated by comparing the position of a nation with that of a private business enterprise. An enterprise has to incur certain costs and expenses in order to stay in business. For our purposes, we are concerned only with one kind of cost -- the cost of managing and administering the business. Such administrative overheads in a business are analogous to the cost of government in a nation. The administrative overheads of a business are low to the extent that everyone working in the business can be trusted to behave in a way that best promotes the interests of the firm. If they can each be trusted to take such responsibilities. and to exercise such initiative as falls within their sphere, then administrative overheads will be low. It will be low because it will be necessary to have only one man looking after each job, without having another man to check upon what he is doing, keep him in line, and report on him to someone else. But if no one can be trusted to act in a loyal and responsible manner towards his job, then the business will require armies of administrators, checkers, and foremen and administrative overheads will rise correspondingly. As administrative overheads rise, so the earnings of the business after meeting he expense of administration, will fall; and the business will have less money to distribute as dividends or invest directly in its future progress and development.

　　It is precisely the same with a nation. To the extent that the people can be relied upon to behave in a loyal and responsible manner, the government does not require armies of police and civil servants to keep them in order. But if a nation is disunited, the government cannot be sure that the actions of the people will be in the interests of the nation; and it will have to watch, check, and control the people accordingly. A disunited nation therefore has to incur unduly high costs of government.

　　如果一个国家实际上处于分裂状态，使之联合起来就是政府的事了。这样的一来就增加了政府的开支，从而相应地减少了可以用来发展国家的那部分经济资源。不应忘记，在一个贫穷落后的国家里，那部分财力是很有限的。凡是政府管理费用高的地方，用于发展国家经济的资金就会相应地减少。

　　把国家的状况同私人企业的状况加以比较，就可以看清这个问题。一个企业为了继续经营，不得不支出一定的费用和开销。就我们的目的而言，我们只关心一种费用 -- 企业行政管理费。一家企业的行政管理开支类似于一个国家的政府管理所用的开支。如果企业中的每个人都在真诚地为提高企业利润而工作，那么企业的管理费用就会降低到相应的程度。如果企业的每个人都信得过，人人都认真负责，在各自的工作范围内发挥主动性，行政管理费用就会降低。行政管理费用降低的原因是：每项工作只需要一个人去完成，用不着另外再有一个人检查工作。督促他遵守章程，或向有关人士汇报他的工作。但是，如果企业中谁也不可信赖会对工作尽忠守职，那么企业就会需要大批的管理人员、检查人员和带班人员，管理费用就会相应地增加。管理费用增加了，那么在扣除管理费用后，企业的收入就降低了。因此用于分红的金额或直接用于将来开拓和发展的投资就相应地减少了。

　　一个国家的情况也完全相同。如果人民忠于职守，举止规矩，能受到政府的信赖，那么政府就不需要大批的警察和文职人员去促使人民遵纪守法。但是，如果一个国家处于分裂状态，政府不能相信人民的行动有利于国家，那么政府就不得不对人民进行监督、检查和控制。因此，一个处于分裂的国家必须要支付过高的行政管理费用。

新概念第四册Lesson38课文翻译及学习笔记

　　【课文】

　　First listen and then answer the following question.

　　听录音，然后回答以下问题。

　　What does this text describe?

　　Contamination of water supplies is usually due to poor sanitation close to water sources, sewage disposal into the sources themselves, leakage of sewage into distribution systems or contamination with industrial or farm waste. Even if a piped water supply is safe at its source, it is not always safe by the time it reaches the tap. Intermittent tap-water supplies should be regarded as particularly suspect.

　　Travellers on short trips to areas with water supplies of uncertain quality should avoid drinking tap-water, or untreated water from any other source. It is best to keep to hot drinks, bottled or canned drinks of well-known brand names -- international standards of water treatment are usually followed at bottling plants. Carbonated drinks are acidic, and slightly safer. Make sure that all bottles are opened in your presence, and that their rims are clean and dry.

　　Boiling is always a good way of treating water. Some hotels supply boiled water on request and this can be used for drinking, or for brushing teeth. Portable boiling elements that can boil small quantities of water are useful when the right voltage of electricity is available. Refuse politely any cold drink from an unknown source.

　　Ice is only as safe as the water from which it is made, and should not be put in drinks unless it is known to be safe. Drink can be cooled by placing them on ice rather than adding ice to them.

　　Alcohol may be a medical disinfectant, but should not be relied upon to sterilize water. Ethanol is more effective at a concentration of 50-70 per cent; below 20 per cent, its bactericidal action is negligible. Spirits labelled 95 proof contain only about 47 per cent alcohol. Beware of methylated alcohol, which is very poisonous, and should never be added to drinking water.

　　If no other safe water supply can be obtained, tap water that is too hot to touch can be left to cool and is generally safe to drink. Those planning a trip to remote areas, or intending to live in countries where drinking water is not readily available, should know about the various possible methods for making water safe.

　　【参考译文】

　　水源的污染通常是由于接近水源的地方卫生条件太差而造成的：污水排入水源，污水渗入给水系统或工农业污水造成污染。即使管道供水系统在水源处安全的，等水到达龙头时就不一定总是安全的了。断断续续的水管应该被视为是非常可疑的。

　　短途旅行到水质不保险的地区时，应避免饮用水龙头的水或未经处理任何其他来源的水。仅饮用开水，瓶装或罐装水 -- 装瓶厂通常遵循国际水处理的标准。碳酸饮料是酸性的，就更安全一些。确保瓶子是当你面开启的，瓶口清洁干燥。

　　烧开一直是水处理的一种好办法。有的酒店根据要求可提供开水，这些开水可用于饮用和刷牙。如果有相配的电压，可以煮少量水的便携式热水装置是有用的。应谢绝任何不明来源的冷饮。

　　冰块只有当制造冰块的水安全时才是保险的，只有知道冰块安全时才能加入饮料。可以把饮料置于冰块之上来冷却，而不是把冰块加进饮料之中。

　　酒精可能是医学上的消毒剂，但决不可用来消毒饮用水。乙醇的浓度为50%至70%时比较有效，浓度低于20%时，杀菌能力基本上就不存在了。强度标为95的酒中含有47%的酒精。要提防甲基化酒精，那是剧毒的，永远不能掺入饮用水。

　　如果没有其他安全的饮用水，水管中流出的烫手的水可以留下来冷却。这种水一般是安全的。那些计划去偏远地区旅行，或在饮用水不现成的国家居住的人，应该知道如何使水适于饮用的各种办法。

新概念第四册Lesson39课文翻译及学习笔记

　　【课文】

　　First listen and then answer the following question.

　　听录音，然后回答以下问题。

　　What does the 'uniquely rational way' for us to communicate with other intelligent beings in space depend on?

　　We must conclude from the work of those who have studied the origin of life, that given a planet only approximately like our own, life is almost certain to start. Of all the planets in our solar system, we ware now pretty certain the Earth is the only one on which life can survive. Mars is too dry and poor in oxygen, Venus far too hot, and so is Mercury, and the outer planets have temperatures near absolute zero and hydrogen-dominated atmospheres. But other suns, start as the astronomers call them, are bound to have planets like our own, and as is the number of stars in the universe is so vast, this possibility becomes virtual certainty. There are one hundred thousand million starts in our own Milky Way alone, and then there are three thousand million other Milky Ways, or galaxies, in the universe. So the number of the stars that we know exist is now estimated at about 300 million million million.

　　Although perhaps only 1 per cent of the life that has started somewhere will develop into highly complex and intelligent patterns, so vast is the number of planets, that intelligent life is bound to be a natural part of the universe.

　　If then we are so certain that other intelligent life exists in the universe, why have we had no visitors from outer space yet? First of all, they may have come to this planet of ours thousands or millions of years ago, and found our then prevailing primitive state completely uninteresting to their own advanced knowledge. Professor Ronald Bracewell, a leading American radio astronomer, argued in Nature that such a superior civilization, on a visit to our own solar system, may have left an automatic messenger behind to await the possible awakening of an advanced civilization. Such a messenger, receiving our radio and television signals, might well re-transmit them back to its home-planet, although what impression any other civilization would thus get from us is best left unsaid.

　　But here we come up against the most difficult of all obstacles to contact with people on other planets -- the astronomical distances which separate us. As a reasonable guess, they might, on an average, be 100 light years away. (A light year is the distance which light travels at 186,000 miles per second in one year, namely 6 million million miles.) Radio waves also travel at the speed of light, and assuming such an automatic messenger picked up our first broadcasts of the 1920's, the message to its home planet is barely halfway there. Similarly, our own present primitive chemical rockets, though good enough to orbit men, have no chance of transporting us to the nearest other star, four light years away, let alone distances of tens or hundreds of light years.

　　Fortunately, there is a 'uniquely rational way' for us to communicate with other intelligent beings, as Walter Sullivan has put it in his excellent book, We Are not Alone. This depends on the precise radio frequency of the 21-cm wavelength, or 1420 megacycles per second. It is the natural frequency of emission of the hydrogen atoms in space and was discovered by us in 1951; it must be known to any kind of radio astronomer in the universe.

　　Once the existence of this wave-length had been discovered, it was not long before its use as the uniquely recognizable broadcasting frequency for interstellar communication was suggested. Without something of this kind, searching for intelligences on other planets would be like trying to meet a friend in London without a pre-arranged rendezvous and absurdly wandering the streets in the hope of a chance encounter.

　　【参考译文】

　　根据研究生命起源的人们所作的工作，我们必然会得出这样的结论：如果设想有一颗行星和我们地球的情况基本相似，那几乎肯定会产生生命。我们目前可以肯定的是，在我们太阳系的所有行星中，地球是生命能存在的行星。火星太干燥又缺氧，金星太热，水星也一样。除此之外，太阳系的其他行星的温度都接近绝对零度，并围绕着以氢气为主的大气层。但是，其他的太阳，既天文学家所说的恒星，肯定会有像我们地球一样的行星。因为宇宙中恒星的数目极其庞大，所以存在着产生生命星球的这种可能性是肯定无疑的。仅我们的银河系就有1000亿颗星，况且在宇宙中还有30亿个天河，即银河系。因此，我们所知道的现有恒星数目估计约有30亿X1000亿颗。

　　虽然在已经产生生命的某个地方，可能只有1%会发展成高度复杂有智力的生命形态，但是行星的数目是那么庞大，有智力的生命必然是宇宙的自然组成部分。

　　既然我们如此坚信宇宙中存在着其他有智力的生命，那么我们为什么还未见到外层空间来访的客人呢?首先，他们可能在几千年前或几百年前已来过我们地球，并且发现我们地球那时普遍存在着的原始状态同他们的先进的知识相比是索然无味的。美国一位重要的射电天文学家罗纳德.布雷斯韦尔教授在《自然》杂志上提出了这样的观点：假如有如此高级文明生命访问了我们的太阳系，很可能会在离开太阳系时留下自动化信号装置，等待先进文明的觉醒。这种自动化信息装置，在接收到我们的无线电和电视信号后，完全有可能把这些信号发回到原来的行星。至于其他文明行星对我们地球会有什么印象，还是不说为好。

　　然而，在和外星人联系中我们遇到的困难是分隔我们的天文距离。据合理推算，外星人离我们平均距离也有100光年之远(1光年是光以每秒186，000英里的速度在一年内走的距离即6万亿英里)。无线电波也是以光速传播的。假定外星人的这种自动化信息装置接收了我们二十世纪二十年代的第一次广播信号，那么这个信号在发回到原来的行星途中刚刚走了一半路程。同样，我们目前使用的原始化学火箭，虽然把人送入轨道，但尚不能把我们送到离我们最近、相距4光年的其他星球上去，更不用说几十光年或几百光年远的地方了。

　　幸运的是，有一种我们可以和其他智力生命通迅联系的“合理的方法”，正如活尔特.沙利方在其杰作《我们并不孤独》中阐述的。这种通迅联系要靠21厘米波段，即每秒1420兆周的精确无线电频率。这个频率是空间氢原子释放的自然频率，是在1951年被人类发现的。这个频率是宇宙中任何射电天文学家都应该熟悉的。

　　一旦这种波长的实际存在被发现，提出把它作为星际间可辨认的广播频率就为期不远了。没有这手段，要想寻觅其他星球上的智力生命，就如同去伦敦见一位朋友，事先未约定地点，而荒唐地在街上游逛，以期待碰巧遇上一样。
