感谢等待，现为你提供忠实反映原文的正确译文。今后如有经济学方面的问题，欢迎提问后通知一声，会尽量抽时间帮你忙的。我们在第五栏里既包括了资本总额，也包括了会计标准。资本总量的系数与零再没有区别，其幅度降至第一栏资本总额的五分之一。当我们用国内私营部门的信贷取代资本总量时（系数不详），也获得了类似的结果。这表明，会计标准囊括了载于资本化措施中的发展情况信息。因此，我们将在本文下面部分采用会计标准作为我们衡量发展的尺度。不过，读者足可以放心，从质量上来说，所得出的结果跟使用资本化措施来衡量发展的结果是类似的。
Macroeconomics is a sub-field of economics that examines the behavior of the economy as a whole, once all of the individual economic decisions of companies and industries have been summed. Economy-wide phenomena considered by macroeconomics include Gross Domestic Product (GDP) and how it is affected by changes in unemployment, national income, rate of growth, and price levels. In contrast, microeconomics is the study of the economic behaviour and decision-making of individual consumers, firms, and industries. Macroeconomics can be used to analyze how to influence government policy goals such as economic growth, price stability, full employment and the attainment of a sustainable balance of payments. Macroeconomics is sometimes used to refer to a general approach to economic reasoning, which includes long term strategies and rational expectations in aggregate behavior. Until the 1930s most economic analysis did not separate out individual economics behavior from aggregate behavior. With the Great Depression of the 1930s, suffered throughout the developed world at the time, and the development of the concept of national income and product statistics, the field of macroeconomics began to expand. Particularly influential were the ideas of John Maynard Keynes, who formulated theories to try to explain the Great Depression. Before that time, comprehensive national accounts, as we know them today, did not exist . One of the challenges of economics has been a struggle to reconcile macroeconomic and microeconomic models. Starting in the 1950s, macroeconomists developed micro-based models of macroeconomic behavior (such as the consumption function). Dutch economist Jan Tinbergen developed the first comprehensive national macroeconomic model, which he first built for the Netherlands and later applied to the United States and the United Kingdom after World War II. The first global macroeconomic model, Wharton Econometric Forecasting Associates LINK project, was initiated by Lawrence Klein and was mentioned in his citation for the Nobel Memorial Prize in Economics in 1980. Theorists such as Robert Lucas Jr suggested (in the 1970s) that at least some traditional Keynesian (after British economist John Maynard Keynes) macroeconomic models were questionable as they were not derived from assumptions about individual behavior, although it was not clear whether the failures were in microeconomic assumptions or in macroeconomic models. However, New Keynesian macroeconomics has generally presented microeconomic models to shore up their macroeconomic theorizing, and some Keynesians have contested the idea that microeconomic foundations are essential, if the model is analytically useful. An analogy might be that the fact that quantum phisics is not fully consistent with relativity theory doesn´t mean that realtivity is false. Many important microeconomic assumptions have never been proved, and some have proved wrong. The various schools of thought are not always in direct competition with one another - even though they sometimes reach differing conclusions. Macroeconomics is an ever evolving area of research. The goal of economic research is not to be "right," but rather to be accurate. It is likely that none of the current schools of economic thought perfectly capture the workings of the economy. They do, however, each contribute a small piece of the overall puzzle. As one learns more about each school of thought, it is possible to combine aspects of each in order to reach an informed synthesis. The traditional distinction is between two different approaches to economics: Keynesian economics, focusing on demand; and supply-side (or neo-classical) economics, focusing on supply. Neither view is typically endorsed to the complete exclusion of the other, but most schools do tend clearly to emphasize one or the other as a theoretical foundation. • Keynesian economics focuses on aggregate demand to explain levels of unemployment and the business cycle. That is, business cycle fluctuations should be reduced through fiscal policy (the government spends more or less depending on the situation) and monetary policy. Early Keynesian macroeconomics was "activist," calling for regular use of policy to stabilize the capitalist economy, while some Keynesians called for the use of incomes policies. • Supply-side economics delineates quite clearly the roles of monetary policy and fiscal policy. The focus for monetary policy should be purely on the price of money as determined by the supply of money and the demand for money. It advocates a monetary policy that directly targets the value of money and does not target interest rates at all. Typically the value of money is measured by reference to gold or some other reference. The focus of fiscal policy is to raise revenue for worthy government investments with a clear recognition of the impact that taxation has on domestic trade. It places heavy emphasis on Say's law, which states that recessions do not occur because of failure in demand or lack of money. • Monetarism, led by Milton Friedman, which holds that inflation is always and everywhere a monetary phenomenon. It rejects fiscal policy because it leads to "crowding out" of the private sector. Further, it does not wish to combat inflation or deflation by means of active demand management as in Keynesian economics, but by means of monetary policy rules, such as keeping the rate of growth of the money supply constant over time. • New Keynesian economics, which developed partly in response to new classical economics, strives to provide microeconomic foundations to Keynesian economics by showing how imperfect markets can justify demand management. • Austrian economics is a laissez-faire school of macroeconomics. It focuses on the business cycle that arises from government or central-bank interference that leads to deviations from the natural rate of interest. • Post-Keynesian economics represents a dissent from mainstream Keynesian economics, emphasizing the role of uncertainty and the historical process in macroeconomics. • New classical economics. The original theoretical impetus was the charge that Keynesian economics lacks microeconomic foundations -- . its assertions are not founded in basic economic theory. This school emerged during the 1970s. This school asserts that it does not make sense to claim that the economy at any time might be "out-of-equilibrium". Fluctuations in aggregate variables follow from the individuals in the society continuously re-optimizing as new information on the state of the world is revealed. Later yielded an explicit school which argued that macro-economics does not have micro-economic foundations, but is instead the tool of studying economic systems at equilibrium. 宏观经济学是一种分场经济学的行为,研究是在整个经济中,一旦所有的个人的经济决策,为公司和产业被。宏观经济学认为经济现象包括国内生产总值(GDP)以及它是如何变化影响失业的国民收入的)经济成长率、价格水平。相反,微观经济学研究的就是经济行为和决策的个体消费者,公司和行业。宏观经济学可以用来分析如何影响政府的政策的目标,比如经济增长,价格稳定,充分就业和获取可持续国际收支差额。宏观经济学有时用来指一个经济理论的主要途径,包括长期战略的期望和理性综合行为。直到30年代为止,大部分的经济分析没有独立的个人经济综合行为举止。与1930年代的经济大萧条,遭受了在所有发达国家,发展国民收入的概念和产品的统计数据,但是研究领域的宏观经济学开始扩展。具有特殊影响力的想法是,约翰•梅纳德凯恩斯理论,努力向他们解释制定了经济大萧条。在那时候,综合国民经济核算,如同我们知道他们今天,是不存在的。经济学的一个挑战是一场斗争调和宏观经济政策和微观经济政策,模型。开始于20世纪50年代,macroeconomists发达micro-based模型的宏观经济行为(如消费函数)。1月Tinbergen荷兰经济学家第一个全面发展国家宏观经济模型,该模型他第一次建成为荷兰和后应用于美国和英国二战之后。第一个全球宏观经济模型,沃顿计量预测伙伴联系工程项目,发生在劳伦斯发起克莱恩和被提及他的嘉奖经济学诺贝尔经济学奖1980年。理论家如罗伯特·卢卡斯认为(是在上世纪70年代),认为至少有一些传统的凯恩斯(英国经济学家约翰梅纳德凯恩斯)宏观经济模型都是可疑的,因为他们不是来源于假设的个人行为,虽然现在还不清楚这些失败在微观经济的假定,或是对宏观经济模型。然而,最新凯恩斯主义的宏观微观模型提出了大致以支持他们的宏观经济理论有争议,一些凯恩斯主义者的想法,微观经济基础是必要的,如果模型是分析有用的。打个比方可能是,这样的事实,即量子phisics并不完全符合相对论´,并不代表没有realtivity是假的。许多重要的微观经济假设从来没有被证明,而有些人的证明是错误的。各种各样的思想学派并不总是在彼此的直接竞争,尽管他们有时会达到不同的结论。宏观经济学是一种前所未有的领域的研究。研究经济学的目标不是"正确",而是是精确的。很有可能是学校目前尚无一个经济思想完全捕捉运作方式的经济。不过,他们的贡献每一小块整体难题。当你学会更多关于每个思想学派,它能把方面的每一个为了达到一个通知的合成。传统的区别是留给经济学两种不同的方法,重点凯恩斯经济学和供方需求;(或古典)经济学、关注供应。也都是典型的观点完全排除其他,但大多数学校都往往清晰地强调一个或另一个是的理论基础。•凯恩斯经济学交融在总需求,以解释失业率和商业周期。商业周期波动,应减少通过财政政策(政府花费或多或少根据实际情况)和货币政策。早期凯恩斯主义的宏观经济学是“活动家,定期使用《召唤的政策稳定资本主义经济,虽然有些凯恩斯主义要求使用收入政策。•供给的经济学的作用很明显地在当前货币政策与财政政策。关注于货币政策应该是完全对价格的钱所确定的货币供应的需求的特点,为了金钱。它提倡货币政策,直接目标钱的价值,不目标利率。典型的钱的价值在于用参考金或其他参考。财政政策的重点是提高政府农业投资价值的收入为一个明确的认识税收的影响在国内贸易。它设置了过度强调了说的法律,它表明不会发生经济衰退需求下降、因为没有缺钱。•货币主义的带领下,由弗里德曼,认为始终通货膨胀是一种货币现象。财政政策拒绝,因为会导致“挤退”的私人生活。此外,它不希望对抗通货膨胀或通货紧缩采用主动需求管理在凯恩斯经济学,通过货币政策规则,即坚持的增长速度恒定的钱。凯恩斯•新经济发达的部分原因是为了适应新古典经济学、致力于提供凯恩斯现代经济学的微观经济基础显示出了市场的不完善就能名正言顺的需求管理等。•奥地利经济学是个自由放任主义的学校的宏观经济。它侧重于商业周期,而政府或中央银行的干扰导致偏离自然失业率的兴趣。•Post-Keynesian经济学所代表了凯恩斯经济学主流的作用,强调历史过程中不确定性和宏观经济。•新古典经济学。原理论动力的费用是凯恩斯经济学缺乏有效的微观经济基础——亦即其断言不成立于基本经济理论。这所学校出现在20世纪70年代。这所学校断言它是没有道理的主张经济会随时out-of-equilibrium”。波动的总变量遵从的在这个社会的个人不断re-optimizing新信息的状态的世界就会显现出来。后来取得了一个显式学校一样,认为宏观经济学没有微观经济基础,反而学习经济系统的工具在平衡。

Cultural integration of the Yangtze River Delta region and of regional economic cooperation Abstract: The regional cultural integration of the Yangtze River Delta to promote regional economic cooperation. Analysis of the cultural integration of the Yangtze River Delta region and status of the foundation to explore the cultural integration of regional economic cooperation to promote the role. On this basis, the proposed cultural integration of the Yangtze River Delta regional economic cooperation to promote the four initiatives: to build the cultural circle, a win-win situation of cultural industries, cultural organizations and co-prosperity, as well as the sharing of cultural achievements. Key words: Yangtze River Delta region; cultural integration; for Economic Co-operation At present, the Yangtze River Delta (hereinafter referred to as the Yangtze River Delta) regional economic cooperation is in full swing to start the economic integration is also shown a good trend. But to maintain this momentum forward to a higher level, from regional economic cooperation towards regional economic integration, there are many areas to be strengthened. Integration of regional culture, and for regional economic cooperation and provide more and better opportunity, which is an important part. First, the regional cultural integration of regional economic cooperation to promote the role of Sources of cultural integration is different, different in nature, as well as goal orientation, different cultural values, through mutual absorption, melting, and tend to reconcile the process of integration. Cultural integration can be reflected in the cultural industries, cultural organizations, cultural achievements, such as "浅层次" also can be reflected in the cultural circle, and cultural concepts such as "deep-seated" as well. For a region, economic cooperation and cultural integration is the "catalyst" and "lubricant" of regional economic cooperation with the meaning of the following aspects. (A) cultural integration of regional economic cooperation is one of the forms in many cases, regional economic cooperation and cultural integration are complementary to each other, and cultural integration in itself is one form of economic cooperation through regional and cultural integration can be a different economic regions resources linked to the regional business, travel, culture, after the market opened up, speed up passenger flow, goods flow, information flow, capital flow of the operation, to attract more participation of social resources in order to produce good results. In this regard, the Yangtze River Delta region had a number of useful attempts. For example, in 2004, Shanghai Circus City Performing Arts Group and Jiangsu Province, Zhejiang Province total acrobatics Mission quyi signed the "Yangtze River Delta Cultural Cooperation Agreement", to form the introduction of the project tour "industry chain", joint venture, co-operation. Fox brothers introduced animals white tiger magic show, the Netherlands, Hans • Crocker "magic history" programs, in Jiangsu, Zhejiang and Shanghai to perform, due to increased screening performance, effectively reducing the cost of the introduction of the project, resulting in a very good cost-effectiveness . Like the West Lake Expo in Hangzhou in Zhejiang Province, Haining international tide Festival, Summer Xinanjiang Jiande, Zhoushan International Sand Sculpture Festival and other cultural activities in Shanghai has attracted a large number of inputs of capital and social resources. Shanghai International Arts Festival, International Film Festival, Television Festival, travel section and so on, as well as the capital of Zhejiang's private investment to create a broad space, has brought about tremendous business opportunities. The above project is a regional cultural integration process, but also the process of economic cooperation, a strong culture and economy to achieve a win-win. (B) cultural integration can enhance the overall competitiveness of the regional inter-regional competition in the future more power in the culture, systems, and management, and opening up and the order of 5 and so the "soft power" elements of the cultural force which the Home the first five elements in regional development in the increasingly important to highlight the status and role. • well-known American sociologist Daniel Bell has said that "culture has become part of our civilization's most dynamic component, the energy than the technology itself," "the ultimate direction for the economy but not the price system in which survival cultural value system "[1] 79. And integration of regional culture is an important function of a regional community, will force different cultures together. After the integration of cultural cohesion in regional economic cooperation is an indispensable element, it will help to mobilize all social resources for regional economic and social coordination, as well as common development. At the same time, cultural integration for deeper regional economic cooperation in a spirit of power, its influence is not only realistic, but also far-reaching. Especially for an inter-regional administration, the cultural integration of the cohesion is very important for cooperation. Only the cities in the Yangtze River Delta region to form joint regional culture can be in the increasingly intense domestic and international competition in the region to gain a head start, and even the formation of China's economic growth the world economy.
With the development of economic globalization and China's accession China, world economic and trade activities frequently, goods import and export increased gradually, China foreign trade is in a rapid development phase of the rise, the profound influences of economic globalization on China's economic development. In recent years, with China's opening-up, further liberalization of foreign trade import and export rights, more and more small and medium-sized enterprises and private enterprises began to direct foreign trade business, so the international trade documents is one of the key points in foreign trade. The sale in foreign trade documents, has become an importantbasis and guarantee the transaction, and the work of the business documents and personnel demand also increases, thus improve the quality of business documents, improve the quality of business documents and knowledge level is the inevitable requirement of the development of China's foreign trade, some when documentsoften determines the success of transaction, so the international trade documents in modern international tradeoccupies the position play a decisive role, we need to master the various documents in international a kind of trade documents file, it constitutes a trade circulation program. The documents work throughout the enterprise for export, purchase, transport, in the whole process, workload, time is strong, involve wide, in addition to the coordination between the various departments of foreign trade enterprises, and the bank must also,customs, transportation department, the insurance company, the commodity inspection authorities, the relevant administrative institutions in many aspects contact. Interlocking, mutually affects, mutually for the condition. The documents for delivery and payment for a payment of goods. The documents can prove whether exportersperformance, the performance level, the goods from the importer to documents as evidence of the right goods, thedocuments that have the goods. International trade documents is the important documents of foreign tradebusiness activities, is the original certificate of commodity circulation, it reflects the whole process of commoditycirculation, is the main part of the purpose and significance of this research lies in the practice of their own in Ningbo Huating outdoor products limited experience were summarized, in order to better understand the role and the various types of documents, so as to improve their English level in the application documents, and strive for greater benefits for the company!

主要标准
翻译是语际交流过程中沟通不同语言的桥梁。一般来说，翻译的标准主要有两条：忠实和通顺。
忠实
是指忠实于原文所要传递的信息，也就是说，把原文的信息完整并且准确地表达出来，使译文读者得到的信息与原文读者得到的信息大致相同。
通顺
是指译文规范、明白易懂，没有文理不通、结构混乱、逻辑不清的现象。
实践产生理论，欧美许多国家的翻译理论是五花八门的。从大的方面来看，可以分为两大派：一派是翻译可能论，一派是翻译不可能论。其实，完完全全百分之百的可能是没有的，完完全全百分之百的不可能也是没有的。
世界上一切翻译活动都是在这两个极端之间进行的。欧洲许多著名的人物，比如马丁·路德、M.阿诺德、.纽曼、.波斯特加特、H.白洛克、.诺克斯、V.那巴可夫等等，都对翻译提出了自己的理论。据《开塞尔世界文学百科全书》的意见，这些理论中有些是刚愎自用的。
就是引用一篇跟你的论文题目相关的英文文献，一般是附在论文后面，你所引用的文献就是原文，引用之后需要在原文之后跟着是你翻译出来的翻译稿，就是译文。一般要求都是在5000单词以上，我做毕业 论文的时候对英文文献的题目要求是只要是跟论文题目的所涉及的内容相关就可以。这些东西可以在学校图书馆里或者图书馆网络资料库里找到，就是翻译比较费力，走运的话可以找到带译文的稿子。
就是和你所写的论文有关的英文文献，并将它翻译成中文教你一个讨巧的办法，先找一篇字数差不多的中文文章，然后上GOOGLE的在线翻译把它翻译成英文，这样的话，中文也有了，英文也有了，岂不方便。

On December 3rda Falcon 9 rocket made by SpaceX thundered into the sky. On board were 64 small satellites, more than any American company had launched before in one go. They have an array of uses, from space-based radar to the monitoring of radio-frequency emissions.

This month’s launch is just a taste of what is planned. SpaceX and OneWeb, a communications firm, plan to launch satellites in their thousands, not hundreds (see briefing). The pair are set to double the total number of satellites in orbit by 2027. 这些都属于最新型的近地轨道卫星，在距地表仅几百公里的轨道上绕行。本月发射的只是计划中的以下部分。SpaceX和卫星通信公司OneWeb计划发射几千而不是几百颗卫星。两家公司的目标是让轨道卫星的综述到2027年增加一倍。 【此次发射的卫星都属于最新型近地轨道卫星（LEO），运行轨道距离地面不过几百公里。此次发射活动也只是更宏大计划的牛刀小试。SpaceX和通信公司OneWeb打算发射数以千计的卫星，几百个尚不足为道，到2027年，它们要把在轨卫星的数量增加一倍。】That promises to change things dramatically on Earth. LEO satellites can bring internet connectivity to places where it is still unavailable or unaffordable. This will also be an enduring source of new demand for the space economy. Morgan Stanley, a bank, projects that the space industry will grow from $350bn in 2016 to more than $ by 2040. New internet satellites will account for a half this increase. 这会给地球带来巨大改变。近地轨道卫星可以为目前还未接入互联网或者联网成本过高的地区提供网络连接。而这也将是太空经济新需求的持久源泉。摩根士丹利预测，航天业的规模将从2016年的3500亿美元增长至2040年的超过万亿美元。其中一半的增长将源自新兴互联网卫星。 【这将给人类社会带来巨大改变。有了近地轨道卫星，目前没有网络或者网络太贵的地区就能联网了。太空经济也将因此获得源源不断的新需求。摩根士丹利预测，到2040年，太空行业规模将从2016年的3,500亿美元增长到超过万亿美元，其中一半将来自互联网卫星。】For that to happen, however, three worries must be overcome. Debris is the most familiar concern. As long ago as 1978, Donald Kessler, a scientist at NASA, proposed a scenario in which, when enough satellites were packed into low-Earth orbits, any collision could cause a chain reaction which would eventually destroy all space craft in its orbital plane. The syndrome which bears Mr. Kessler’s name weighs heavily on the minds of executives at the new satellite firms. Debris could conceivably render entire tracts of space unusable for decades. (Collisions have already happened. In 2009 an American satellite and a Russian one crashed into each other above Siberia, sending over a tonne of metal fragments swirling around the planet at thousands of kilometers per hour.) 然而，要实现这一点必须解决三大忧患。其中最为人熟知的一个是空间碎片。早在1978年，美国国家航空航天局的科学家DO哪来的Kessler就提出，当足够多的卫星进入近地轨道时，任何碰撞都可能引起连锁反应，最终破坏所在轨道平面内的所有航天器。这一被命名为“凯斯勒综合症”的理论是压在新型卫星公司高管心头的一块大石。碎片可能导致整个太空轨道在几十年内都无法使用。（碰撞事件已有发生。2009年一颗美国卫星和一颗俄罗斯卫星在西伯利亚上空相撞，产生的一吨多金属碎片以每小时数千公里的速度在地球上空旋转。） 【然而，要实现这一愿景，尚需解决三大问题。太空垃圾首当其冲。1978年，美国国家航空航天局的科学家唐纳德·凯斯勒（Donald Kessler）就曾提出，当近地轨道卫星达到一定的密集程度，一旦发生碰撞，连锁反应将摧毁该轨道平面上的所有航天器。这种情景被命名为“凯斯勒综合症”，给新兴卫星公司高管的心头投下了一片阴影。一旦太空轨道上挤满了碎片，或许数十年都不能再发射航天器了。（太空碰撞已经不再是设想。2009年，一颗美国卫星和一颗俄罗斯卫星在西伯利亚上空相撞，留下了一吨多金属碎片以每小时数千公里的速度在地球上空飞速旋转。）】Solutions exist. One is to grab malfunctioning satellites and pull them down into Earth’s atmosphere. Another is to monitor space more intensively for debris; a US Air Force programme called Space Fence is due to start in 2019. But technology is only part of the answer. Rules are needed to govern the safe disposal of old satellites from low-Earth orbit. The United States’ Federal Communications Commission is revising its regulations with this in mind. Other countries should follow suit. 解决办法是有的。一个方案是“捉住”故障卫星，将其下拉至地球大气层中。另一个方案是更严密地检测太空中的碎片，美国空军一项名为“太空篱笆”（Space Fence）的相关计划将于2019年启动。但技术只是解决方案的一部分，还需要制定规则来管理近地轨道就卫星的安全处置问题。为此美国联邦通信委员会（FCC）正在修订相关规定。其他国家也应效仿。 【解决办法还是有的。首先，可以将发生故障的卫星抓住并拖入地球大气层中。其次，更严密地监控太空碎片；美国空军就将在2019年启动Space Fence（太空篱笆）计划。但是科技只是一个方面。要安全清除近地轨道上的旧卫星，还需要相关政策加持。美国联邦通信委员会（FCC）正在沿着这个思路修订相关规定。其他国家也应如此。】Cyber-security is a second, long-standing worry. Hackers could take control of a satellite and seal intellectual property, redirect data flows or cause a collision. The satellite industry has been slow to respond to such concerns. But as more of the world’s population comes to rely on the infrastructure of space for access to the internet, the need for action intensifies. 第二个担忧存在已久——网络安全。黑客可能劫持卫星，窃取知识产权，重新定向数据流，或者让卫星相撞。卫星行业对这类问题反应迟缓。但随着世界上越来越多人口依赖太空基础设施接入互联网，就此类风险采取行动变得愈加迫切。 【其次，网络安全隐患存在已久。黑客可能劫持卫星，窃取知识产权，重新定向数据流，甚至让卫星相撞。对于这些问题，卫星行业的反应一直很缓慢。但是，越来越多的人口需要依赖太空基础设施才能连接互联网，因此，采取行动已变得十分紧迫。】The third issue follows from the first two. If a simple mistake or a cyber-attack can cause a chain reaction which wipes out hundreds of billions of dollars of investment, who is liable? Underwriters are studying the plans of firms that wish to operate large numbers of satellites. But there is a long way to go before the risks are well understood, let alone priced. 第三个问题因前两者而生。如果一个简单错误或一次网络攻击就可能导致连锁反应，令数千亿美元的投资化为乌有，那么谁该为此负责？保险公司正在研究那些想要运营大量卫星的企业提出的计划。但要充分了解其中的风险尚需时日，更别说要为这些风险定价了。 【问题之三与前两者联系密切。如果一个小小的错误或者一次网络攻击就能引发连锁反应，足以让数百亿美元投资化为乌有，那么这笔账该找谁来算呢？保险公司正在帮助有意运营大量卫星的公司研究保险计划，但是充分了解其中风险尚需时日，要给风险定价岂不是难上加难。】As space becomes more commercialized, mind-bending prospects open up: packages shuttled across the planet in minutes by rocket rather than by plane, mining equipment sent to asteroids, a stream of paying passengers launched to orbit and beyond. All that and more may come, one day. But such activities would raise the same questions as LEO satellites do. They must be answered before the space economy can truly blossom. 随着太空空间变得更商业化，让人脑洞大开的前景渐现：通过火箭而不是飞机在几分钟之内横跨地球递送包裹；把采矿设备发射到小行星上；把付费乘客“发射”到地球轨道或更远的地方。某一天，这些乃至更多的想法也许都会一一实现。但这些活动会和近地轨道卫星引发同样的问题。必须首先回答这些问题，太空经济才能真正开花结果。 【太空的商业化程度越来越高，千奇百怪的想法也纷纷涌现：用火箭代替飞机送快递，几分钟就能穿越地球；把采矿设备发送到小行星上去；花钱买票就能去地球轨道甚至更远的地方。未来某天，或许再光怪陆离的想法也能成真。但是那时，人们还是要面对近地轨道卫星今天面对的问题。只有尽快找到解决办法，太空经济才能真正百花齐放。】

这篇文章有几个非常有意思的句子和表达，我贴出来，大家一起赏析一下： 佳句篇： Sentence 1. He helped popularise the idea that some diseases not previously thought to have a bacterial cause were actually infections, which ruffled many scientific feathers when it was first suggested. 解析： Ruffle弄皱的意思 Ruffle one’s feathers惹怒（想想逆毛流撸猫） The idea that ...用的是同位语从句，不太多，常用搭配是the evidence that，the concept that 等。That后从句解释idea, concept或evidence等。 Which的指代问题。Which指代的不是上文任何一个出现的单词或词组，而是Dr. Cochran的这波操作。Sentence 2. Ashkenazim generally do well in IQ tests, scoring 12-15 points above the mean value of 100, and have contributed disproportionately to the intellectual and cultural life of the West, as the careers of Freud, Einstein and Mahler, pictured above, affirm. disproportionately不成比例地 主干and复合句+非谓语动词scoring+as引导的从句（插入后置定语） 每个部分都不难，集合到一起就对理解产生障碍了。Sentence 3. But in the Middle Ages, success in Christian society tended to be violently aristocratic (warfare and land), rather than peacefully meritocratic (banking and trade). 这个句子不难，为什么拿出来是因为这个violently的用法。简单来讲，这一个单词乍一看是作aristocratic的副词，实则在翻译（以及理解）当中，我们必须单独翻译成一个实意的成分，而且作副词处理。 Aristocratic贵族统治 Meritocratic德治Sentence 4. That small, reproductively isolated groups of people are susceptible to genetic disease is well known. 主语从句，注意 5. Most of the dozen or so disease genes that are common in them belong to one of two types: they are involved either in the storage in nerve cells of special fats called sphingolipids, which form part of the insulating outer sheaths that allow nerve cells to transmit electrical signals, or in DNA repair. 典型长句，如何解析？ Most of the dozen or so disease genes that are common in them belong to one of two types: Or so大约 斜体作的是disease genes they are involved either in the storage in nerve cells of special fats called sphingolipids, which form part of the insulating outer sheaths that allow nerve cells to transmit electrical signals, or in DNA repair. either or后面是两个in... 第一个in后面的which form part of the insulating outer sheaths解释的是Sphingolipids that allow nerve cells to transmit electrical signals解释的是sheaths。 也就是说，（非限制性）定语从句后面紧接另一个定语从句。 第二个in后面很简单，但！！！文章最后一段有解释，对于 文章结构 至关重要。Sentence 6&7. Thus, the theory goes, the pressure to keep the sickle-cell gene in the population because of its malaria-protective effects balances the pressure to drive it out because of its anaemia-causing effects. It therefore persists without becoming ubiquitous. 两句话放一起。 主干已加黑。很有意思的句子，工整、对仗，而又解释非常清楚。 下一句，persist和ubiquitous用词极其精准，整句话像外科手术般，精准简练。作者还是怕读者一下子没读懂，用简单而又高效的句子总结下。写作手法很老练高超，字字玑珠，像极了宝马M3。Sentence 8. Genes that promote intelligence in an individual when present as a single copy create disease when present as a double copy. 乍一看没什么稀奇，再一看，把一个comparison分别放在了主语和谓语的修饰成分中，可谓老辣。 作何解？ That promote intelligence对genes做了一个限定，指的是genes的其中一种特征，然后用when说明了适用情况。 Create谓语的主语也是genes，但这时候是没有限定的genes。Create disease做的是限定，其实对应的是promote intelligence。后面同样用一个when来说明范围。 简单来讲，genes的含义做了一个缩小和限定，又在create的时候恢复了genes的双重功能含义。 Promote intelligence和create diseases一个对应，尽管成分差别很大。 两个when的对比。 可谓神句。Sentence 9. An Israeli clinic devoted to treating people with Gaucher's has vastly more engineers, scientists, accountants and lawyers on its books than would be expected by chance. Than (what) would be expected by chance. 省略了what。。。你能理解吗？ 还有这个books，这个同语境关联强烈。好的表达： 1. ruffle one’s feather 2. Tremble at the thought 3. Affirm作不及物动词（Ashkenazim generally do well in IQ tests, scoring 12-15 points above the mean value of 100, and have contributed disproportionately to the intellectual and cultural life of the West, as the careers of Freud, Einstein and Mahler, pictured above, affirm. ） 4. aristocratic . meritocratic 5. Exact a price类似用法 exert influence附原文及翻译： Natural genius? 天生我才？ The high intelligence of Ashkenazi Jews may be a result of their persecuted past 德系犹太人的高智商或许是因为曾经遭受迫害的后果 THE idea that some ethnic groups may, on average, be more intelligent than others is one of those hypotheses that dare not speak its name. But Gregory Cochran, a noted scientific iconoclast, is prepared to say it anyway. He is that rare bird, a scientist who works independently of any institution. He helped popularise the idea that some diseases not previously thought to have a bacterial cause were actually infections, which ruffled many scientific feathers when it was first suggested. And more controversially still, he has suggested that homosexuality is caused by an infection. 某些少数民族的平均智商高于其他民族这一说法，是很多不敢公开的假设之一。不过著名的科学狂人Gregory Cochran 决意要做第一个吃螃蟹的人。他很特别，总是独立工作而不属于任何机构。某些曾被诊断并非病菌引起的疾病，其实病源来自传染病。这一观点因他的推动受到了关注。此观点一经提出，就受到了许多科学家的反对。这还不算，更具争议的是，他认为同性恋也是由传染病引起的。 Even he, however, might tremble at the thought of what he is about to do. Together with Jason Hardy and Henry Harpending, of the University of Utah, he is publishing, in a forthcoming edition of the Journal of Biosocial Science, a paper which not only suggests that one group of humanity is more intelligent than the others, but explains the process that has brought this about. The group in question are Ashkenazi Jews. The process is natural selection. 然而就算是Cochran，也为自己接下来要做的事捏了一把汗。他准备同Utah大学的Jason Hardy与Henry Harpending一同，在最新一期的《生物社会科学杂志》发表一篇论文，文中不仅提出了某一少数民族比其他民族更聪明这一观点，还解释了这一结果产生的过程。文中两大主角就是德系犹太人和自然选择。 History before science 不管是否科学，先来看看历史 Ashkenazim generally do well in IQ tests, scoring 12-15 points above the mean value of 100, and have contributed disproportionately to the intellectual and cultural life of the West, as the careers of Freud, Einstein and Mahler, pictured above, affirm. They also suffer more often than most people from a number of nasty genetic diseases, such as Tay-Sachs and breast cancer. These facts, however, have previously been thought unrelated. The former has been put down to social effects, such as a strong tradition of valuing education. The latter was seen as a consequence of genetic isolation. Even now, Ashkenazim tend to marry among themselves. In the past they did so almost exclusively. 德系犹太人不仅在IQ测试上表现不俗，正常人一般在100分左右，而他们大多都能得个112-115分，而且虽然人数不多，但他们在欧洲知识、文化生活中的地位却举足轻重。想想弗洛伊德、爱因斯坦、马勒，我们就会点头称是了。但同时，他们中患有如泰-萨克斯病、乳腺癌这类严重的遗传疾病的比率明显高于其他种族。这些事实，最初被人们认为是毫无联系的。前者被说成是社会原因引起的，如浓烈的价值观教育的传统；后者则被说成是基因隔离的结果，不过即使是现在，德系犹太人还是愿意同本族人结婚，在过去，就更是如此了。 Dr Cochran, however, suspects that the intelligence and the diseases are intimately linked. His argument is that the unusual history of the Ashkenazim has subjected them to unique evolutionary pressures that have resulted in this paradoxical state of affairs. 但Cochran博士对以上两点表示质疑，并认为德系犹太人的天赋异禀与痛病缠身联系密切。他认为正是异常的历史环境强加给了德系犹太人独有的进化压力，才导致了这些看似奇怪的现象。 Ashkenazi history begins with the Jewish rebellion against Roman rule in the first century AD. When this was crushed, Jewish refugees fled in all directions. The descendants of those who fled to Europe became known as Ashkenazim. 德系犹太人的历史源于公元1世纪。犹太人在反对罗马人的统治失败后，犹太难民四散而逃，逃亡欧洲的犹太后裔就是如今的德系犹太人。 In the Middle Ages, European Jews were subjected to legal discrimination, one effect of which was to drive them into money-related professions such as banking and tax farming which were often disdained by, or forbidden to, Christians. This, along with the low level of intermarriage with their gentile neighbours (which modern genetic analysis confirms was the case), is Dr Cochran's starting point. 在中世纪，欧洲的犹太人在法律上地位很不平等，结果之一就是他们不得不从事与金钱相关的职业，如被人看不起或不准基督徒涉足的银行或征税工作，此外，他们只能与邻居中社会地位较低的非犹太人通婚（这种状况通过现代基因学分析得到了证实）。上述就是Cochran 博士论文的起点。 He argues that the professions occupied by European Jews were all ones that put a premium on intelligence. Of course, it is hard to prove that this intelligence premium existed in the Middle Ages, but it is certainly true that it exists in the modern versions of those occupations. Several studies have shown that intelligence, as measured by IQ tests, is highly correlated with income in jobs such as banking. 他认为欧洲犹太人从事的职业都是些需要一定智商的职业，虽不能证明这些职业在中世纪时就是这样了，但在当代它们确实如此。一些研究表明，智力水平（按智力测试的标准来算）与工资水平（如那些从事银行工作的人）联系密切。 What can, however, be shown from the historical records is that European Jews at the top of their professions in the Middle Ages raised more children to adulthood than those at the bottom. Of course, that was true of successful gentiles as well. But in the Middle Ages, success in Christian society tended to be violently aristocratic (warfare and land), rather than peacefully meritocratic (banking and trade). 这些历史记录证明了，那些在欧洲工作地位较高的犹太家庭子女存活率要高于那些地位较低的犹太家庭。情况对于那些其他种族的也是一样的。但在中世纪，基督教社会中所谓的成功多是贵族通过战争与土地强争豪取，而非通过量才而用（如从事银行或贸易工作）和平地获得。 Put these two things together—a correlation of intelligence and success, and a correlation of success and fecundity—and you have circumstances that favour the spread of genes that enhance intelligence. The questions are, do such genes exist, and what are they if they do? Dr Cochran thinks they do exist, and that they are exactly the genes that cause the inherited diseases which afflict Ashkenazi society. 把智力与成功的关联以及成功与生殖力的关系合二为一，你就具备了有利于智商提高的基因传播的条件。问题是这种智商基因确实存在吗？假如它果真存在的话，那究竟是什么呢？科克伦博士认为它们的确存在，而且正是那种引起折磨德系犹太人遗传疾病的基因。 That small, reproductively isolated groups of people are susceptible to genetic disease is well known. Constant mating with even distant relatives reduces genetic diversity, and some disease genes will thus, randomly, become more common. But the very randomness of this process means there should be no discernible pattern about which disease genes increase in frequency. In the case of Ashkenazim, Dr Cochran argues, this is not the case. Most of the dozen or so disease genes that are common in them belong to one of two types: they are involved either in the storage in nerve cells of special fats called sphingolipids, which form part of the insulating outer sheaths that allow nerve cells to transmit electrical signals, or in DNA repair. The former genes cause neurological diseases, such as Tay- Sachs, Gaucher's and Niemann-Pick. The latter cause cancer. 众所周知，越是人口稀少并且生育范围狭小的种族就越易患遗传疾病。总是于同族人通婚，就算不是近亲，也会较少遗传的多样性，同时也会使某些致病基因没有规律地在该种族内部泛滥起来。而这种无规律性意味着人们不知道何类致病基因会被大量传播。但对德系犹太人来说，Cochran 医生指出，情况却并非如此。他们当中最常见的十几种疾病基因基本上可以归结于两类：一类参与神经细胞中鞘脂类特殊脂肪）的储存。鞘脂组成一部分绝缘外层鞘，允许神经细胞发射电子信号。另一类参与DNA 的修复。前者基因会引发神经性疾病，如泰萨二氏病、脑苷脂沉积病和神经鞘磷脂沉积病；而后者会导致癌症。 That does not look random. And what is even less random is that in several cases the genes for particular diseases come in different varieties, each the result of an independent original mutation. This really does suggest the mutated genes are being preserved by natural selection. But it does not answer the question of how evolution can favour genetic diseases. However, in certain circumstances, evolution can. 上述看起来并非毫无规律。而且更趋于规律的表现就是，在一些病例中，特殊疾病的致病基因来自于不同的变体，而每个变体都是独立的原基因变异的结果。这就印证了变异基因是自然选择保留下来的结果，可它却不能回答自然选择为什么会成了遗传疾病的帮凶，但在一些特殊的条件下，进化能够产生这样的结果。 West Africans, and people of West African descent, are susceptible to a disease called sickle-cell anaemia that is virtually unknown elsewhere. The anaemia develops in those whose red blood cells contain a particular type of haemoglobin, the protein that carries oxygen. But the disease occurs only in those who have two copies of the gene for the disease-causing haemoglobin (one copy from each parent). Those who have only one copy have no symptoms. They are, however, protected against malaria, one of the biggest killers in that part of the world. Thus, the theory goes, the pressure to keep the sickle-cell gene in the population because of its malaria-protective effects balances the pressure to drive it out because of its anaemia-causing effects. It therefore persists without becoming ubiquitous. 如西非人以及他们的后代易患一种叫做镰状细胞性贫血的疾病，这种病在西非之外几乎都没人听说过。贫血症发于那些红血球中含有一种特殊的血红蛋白，其蛋白质中含有氧气的人。但这种镰状细胞性贫血症只会发生在同时有两组这种致病的血红蛋白（父母都有这种血红蛋白）的人身上。而那些只有一组的人不但不会患这种贫血症，也不会患疟疾，该病被称为非洲的头号杀手。因此，我们可以这样说，抵御疟疾的特性使得镰状细胞在得以人体中存活下来，同时这种细胞导致贫血症的特性也会被人体排斥，只有在为保持这两种状态而产生的压力达到平衡时，才不会有任何一个特性占据上风。 Dr Cochran argues that something similar happened to the Ashkenazim. Genes that promote intelligence in an individual when present as a single copy create disease when present as a double copy. His thesis is not as strong as the sickle-cell/malaria theory, because he has not proved that any of his disease genes do actually affect intelligence. But the area of operation of some of them suggests that they might. Cochran博士认为，德系犹太人也面临着同样的情况，他们的某些基因如果以单组出现就可以提高智力，一旦以双组出现就会引起疾病。显然，该理论并不如他的镰状细胞/疟疾理论那样具有说服力，因为他尚未证明任何一种致病基因确实能够影响智力，但是某些基因的活动区域显示它们或许真能影响智力。 The sphingolipid-storage diseases, Tay-Sachs, Gaucher's and Niemann-Pick, all involve extra growth and branching of the protuberances that connect nerve cells together. Too much of this (as caused in those with double copies) is clearly pathological. But it may be that those with single copies experience a more limited, but still enhanced, protuberance growth. That would yield better linkage between brain cells, and might thus lead to increased intelligence. Indeed, in the case of Gaucher's disease, the only one of the three in which people routinely live to adulthood, there is evidence that those with full symptoms are more intelligent than the average. An Israeli clinic devoted to treating people with Gaucher's has vastly more engineers, scientists, accountants and lawyers on its books than would be expected by chance. 鞘脂储存类疾病，如泰萨二氏病、脑苷脂沉积病和神经鞘磷脂沉积病，都涉及到连接神经细胞的凸起的多余生长和分叉。显然，这种生长和分叉太多的话就会引起疾病。但是，也有可能，仅有单份致病基因的人会出现比较有限的、但仍然加强了的凸起生长。这将有助于加强脑细胞之间的连接，或许因此导致智力提高。实际上，在脑苷脂沉积病的例子中，在三分之一能够活到成年的患者中，确实有证据表明完全发病的人拥有高于平均值的智商。根据一家专门治疗脑苷脂沉积病的以色列诊所的医疗记录，患者中的工程师、科学家、会计和律师的比例多于常人。 Why a failure of the DNA-repair system should boost intelligence is unclear—and is, perhaps, the weakest part of the thesis, although evidence is emerging that one of the genes in question is involved in regulating the early growth of the brain. But the thesis also has a strong point: it makes a clear and testable prediction. This is that people with a single copy of the gene for Tay-Sachs, or that for Gaucher's, or that for Niemann-Pick should be more intelligent than average. Dr Cochran and his colleagues predict they will be so by about five IQ points. If that turns out to be the case, it will strengthen the idea that, albeit unwillingly, Ashkenazi Jews have been part of an accidental experiment in eugenics. It has brought them some advantages. But, like the deliberate eugenics experiments of the 20th century, it has also exacted a terrible price. 为什么基因修复系统失灵会提高智力，现在还不清楚原因何在。虽然，陆续有证据表明产生问题的基因之一参与了调节大脑的早期发育，但是这仍是该论题最薄弱的环节。不过，该理论也有令人信服的地方：它对于拥有单份泰萨二氏病或脑苷脂沉积病或神经鞘磷脂沉积病基因的人会比普通人更聪明做出了明确而可检验的预测。Cochran 博士和他的同事认为，这些人的智商因此会比平均水平高出5 个点。尽管有人不愿接受，假如确实如此的话，它将有力地证明，德系犹太人在不经意间经历了优生实验，而这为他们带来了智商上的优势。但是，如同发生在20 世纪的人为的优生实验一样，它同样让他们付出了可怕的代价。

On December 3rda Falcon 9 rocket made by SpaceX thundered into the sky. On board were 64 small satellites, more than any American company had launched before in one go. They have an array of uses, from space-based radar to the monitoring of radio-frequency emissions. One, designed by Trevor Paglen, an artist, will soon unfurl a 30-metre reflective structure that will shine down on Earth like an artificial star, visible to the naked eye. 太空正变得越来越拥挤。12月3日，SpaceX制造的一枚猎鹰九号火箭轰隆升空。它上面装载了64颗小型卫星，超过之前任何一家美国公司单次发射卫星的数量。从天基雷达到无线电发射监测，这些卫星的用途多种多样。其中一颗由艺术家Trevor Paglen设计，内嵌的30米场反射器不久将会打开，变成一颗肉眼可见的人造星星，在地球的上空闪光。 【太空越来越拥挤了。12月3日，SpaceX发射了一枚猎鹰9号火箭，这一次共有64颗小型卫星随之升空，创下了美国公司单次发射卫星数量的新纪录。这些卫星用途多样，从天基雷达到无线电监测等十分广泛。其中还包括一颗由艺术家特雷弗·裴格伦（Trevor Paglen）设计的艺术卫星，它将在太空中释放约30米长的反射器，变身为肉眼即可观赏到的人造卫星。】These objects are part of the latest breed of low-Earth-orbit (LEO) satellites, which are designed to whizz around the planet only a few hundred kilometers above its surface. This month’s launch is just a taste of what is planned. SpaceX and OneWeb, a communications firm, plan to launch satellites in their thousands, not hundreds (see briefing). The pair are set to double the total number of satellites in orbit by 2027. 这些都属于最新型的近地轨道卫星，在距地表仅几百公里的轨道上绕行。本月发射的只是计划中的以下部分。SpaceX和卫星通信公司OneWeb计划发射几千而不是几百颗卫星。两家公司的目标是让轨道卫星的综述到2027年增加一倍。 【此次发射的卫星都属于最新型近地轨道卫星（LEO），运行轨道距离地面不过几百公里。此次发射活动也只是更宏大计划的牛刀小试。SpaceX和通信公司OneWeb打算发射数以千计的卫星，几百个尚不足为道，到2027年，它们要把在轨卫星的数量增加一倍。】That promises to change things dramatically on Earth. LEO satellites can bring internet connectivity to places where it is still unavailable or unaffordable. This will also be an enduring source of new demand for the space economy. Morgan Stanley, a bank, projects that the space industry will grow from $350bn in 2016 to more than $ by 2040. New internet satellites will account for a half this increase. 这会给地球带来巨大改变。近地轨道卫星可以为目前还未接入互联网或者联网成本过高的地区提供网络连接。而这也将是太空经济新需求的持久源泉。摩根士丹利预测，航天业的规模将从2016年的3500亿美元增长至2040年的超过万亿美元。其中一半的增长将源自新兴互联网卫星。 【这将给人类社会带来巨大改变。有了近地轨道卫星，目前没有网络或者网络太贵的地区就能联网了。太空经济也将因此获得源源不断的新需求。摩根士丹利预测，到2040年，太空行业规模将从2016年的3,500亿美元增长到超过万亿美元，其中一半将来自互联网卫星。】For that to happen, however, three worries must be overcome. Debris is the most familiar concern. As long ago as 1978, Donald Kessler, a scientist at NASA, proposed a scenario in which, when enough satellites were packed into low-Earth orbits, any collision could cause a chain reaction which would eventually destroy all space craft in its orbital plane. The syndrome which bears Mr. Kessler’s name weighs heavily on the minds of executives at the new satellite firms. Debris could conceivably render entire tracts of space unusable for decades. (Collisions have already happened. In 2009 an American satellite and a Russian one crashed into each other above Siberia, sending over a tonne of metal fragments swirling around the planet at thousands of kilometers per hour.) 然而，要实现这一点必须解决三大忧患。其中最为人熟知的一个是空间碎片。早在1978年，美国国家航空航天局的科学家DO哪来的Kessler就提出，当足够多的卫星进入近地轨道时，任何碰撞都可能引起连锁反应，最终破坏所在轨道平面内的所有航天器。这一被命名为“凯斯勒综合症”的理论是压在新型卫星公司高管心头的一块大石。碎片可能导致整个太空轨道在几十年内都无法使用。（碰撞事件已有发生。2009年一颗美国卫星和一颗俄罗斯卫星在西伯利亚上空相撞，产生的一吨多金属碎片以每小时数千公里的速度在地球上空旋转。） 【然而，要实现这一愿景，尚需解决三大问题。太空垃圾首当其冲。1978年，美国国家航空航天局的科学家唐纳德·凯斯勒（Donald Kessler）就曾提出，当近地轨道卫星达到一定的密集程度，一旦发生碰撞，连锁反应将摧毁该轨道平面上的所有航天器。这种情景被命名为“凯斯勒综合症”，给新兴卫星公司高管的心头投下了一片阴影。一旦太空轨道上挤满了碎片，或许数十年都不能再发射航天器了。（太空碰撞已经不再是设想。2009年，一颗美国卫星和一颗俄罗斯卫星在西伯利亚上空相撞，留下了一吨多金属碎片以每小时数千公里的速度在地球上空飞速旋转。）】Solutions exist. One is to grab malfunctioning satellites and pull them down into Earth’s atmosphere. Another is to monitor space more intensively for debris; a US Air Force programme called Space Fence is due to start in 2019. But technology is only part of the answer. Rules are needed to govern the safe disposal of old satellites from low-Earth orbit. The United States’ Federal Communications Commission is revising its regulations with this in mind. Other countries should follow suit. 解决办法是有的。一个方案是“捉住”故障卫星，将其下拉至地球大气层中。另一个方案是更严密地检测太空中的碎片，美国空军一项名为“太空篱笆”（Space Fence）的相关计划将于2019年启动。但技术只是解决方案的一部分，还需要制定规则来管理近地轨道就卫星的安全处置问题。为此美国联邦通信委员会（FCC）正在修订相关规定。其他国家也应效仿。 【解决办法还是有的。首先，可以将发生故障的卫星抓住并拖入地球大气层中。其次，更严密地监控太空碎片；美国空军就将在2019年启动Space Fence（太空篱笆）计划。但是科技只是一个方面。要安全清除近地轨道上的旧卫星，还需要相关政策加持。美国联邦通信委员会（FCC）正在沿着这个思路修订相关规定。其他国家也应如此。】Cyber-security is a second, long-standing worry. Hackers could take control of a satellite and seal intellectual property, redirect data flows or cause a collision. The satellite industry has been slow to respond to such concerns. But as more of the world’s population comes to rely on the infrastructure of space for access to the internet, the need for action intensifies. 第二个担忧存在已久——网络安全。黑客可能劫持卫星，窃取知识产权，重新定向数据流，或者让卫星相撞。卫星行业对这类问题反应迟缓。但随着世界上越来越多人口依赖太空基础设施接入互联网，就此类风险采取行动变得愈加迫切。 【其次，网络安全隐患存在已久。黑客可能劫持卫星，窃取知识产权，重新定向数据流，甚至让卫星相撞。对于这些问题，卫星行业的反应一直很缓慢。但是，越来越多的人口需要依赖太空基础设施才能连接互联网，因此，采取行动已变得十分紧迫。】The third issue follows from the first two. If a simple mistake or a cyber-attack can cause a chain reaction which wipes out hundreds of billions of dollars of investment, who is liable? Underwriters are studying the plans of firms that wish to operate large numbers of satellites. But there is a long way to go before the risks are well understood, let alone priced. 第三个问题因前两者而生。如果一个简单错误或一次网络攻击就可能导致连锁反应，令数千亿美元的投资化为乌有，那么谁该为此负责？保险公司正在研究那些想要运营大量卫星的企业提出的计划。但要充分了解其中的风险尚需时日，更别说要为这些风险定价了。 【问题之三与前两者联系密切。如果一个小小的错误或者一次网络攻击就能引发连锁反应，足以让数百亿美元投资化为乌有，那么这笔账该找谁来算呢？保险公司正在帮助有意运营大量卫星的公司研究保险计划，但是充分了解其中风险尚需时日，要给风险定价岂不是难上加难。】As space becomes more commercialized, mind-bending prospects open up: packages shuttled across the planet in minutes by rocket rather than by plane, mining equipment sent to asteroids, a stream of paying passengers launched to orbit and beyond. All that and more may come, one day. But such activities would raise the same questions as LEO satellites do. They must be answered before the space economy can truly blossom. 随着太空空间变得更商业化，让人脑洞大开的前景渐现：通过火箭而不是飞机在几分钟之内横跨地球递送包裹；把采矿设备发射到小行星上；把付费乘客“发射”到地球轨道或更远的地方。某一天，这些乃至更多的想法也许都会一一实现。但这些活动会和近地轨道卫星引发同样的问题。必须首先回答这些问题，太空经济才能真正开花结果。 【太空的商业化程度越来越高，千奇百怪的想法也纷纷涌现：用火箭代替飞机送快递，几分钟就能穿越地球；把采矿设备发送到小行星上去；花钱买票就能去地球轨道甚至更远的地方。未来某天，或许再光怪陆离的想法也能成真。但是那时，人们还是要面对近地轨道卫星今天面对的问题。只有尽快找到解决办法，太空经济才能真正百花齐放。】
