核动力;

核能(Nuclear Energy) Nowadays,energy can be obtained through various sources such as oil,coal,natural gas,solar heat,wind,etc.But the conventional energy like oil,coals are being used up rapidly,and solar heat can"t become widely used immediately for technological reason.In my opinion,unclear energy will take the place of conventional energy,because people now can control this energy freely,and unclear energy is non-polluting,inexhaustible,and it"s much safer than coal and oil.Coal and oil are burned,they also produce many harmful gases,and the air has been seriously polluted by such gases,which will threaten people"s living environment.And many accident happened because of the wrong use of such energies. However,such things can"t happen when we use nuclear energy,Though when the nuclear leaks out,it will do great harm to people" s health and the environment.We can do enough work to avoid such things,and limited such things at a low percentage.

核能通常指原子核的能量，可以透过核聚变、核裂变或放射性核衰变释放出来。核能也可以指：核结合能，将原子核里的核子分开所需的能量核势能，粒子在原子核里的势能核动力（nuclear power）也称原子能或核能，使用持续的核裂变产生热和电核技术，核能的应用，包括核动力、核医学、核武器图中＋－号代表不可分割的最小正负电磁信息单位-量子比特（qubit）（名物理学家约翰.惠勒John Wheeler曾有句名言:万物源图于比特 It from bit量子信息研究兴盛后,此概念升华为，万物源于量子比特）注：位元即比特

In physics, energy is defined as the amount of work that can be performed by force, whereas power is defined as the rate at which work is performed. The unit of energy is Joule = Newton*Meter or Joule = Watt*Time, while the unit of power is Watt = Joule/Time.For example, the power of my air conditioner is 1 kW, and the electric bill is 1 kWh for 1 hour.

Nuclear Energy Nowadays, energy can be obtained through various sources such as oil, coal, natural gas, solar heat, wind, etc. But the conventional energy like oil, coals are being used up rapidly, and solar heat can"t become widely used immediately for technological reason. In my opinion, unclear energy will take the place of conventional energy, because people now can control this energy freely, and unclear energy is non-polluting, inexhaustible, and it"s much safer than coal and oil. Coal and oil are burned, they also produce many harmful gases, and the air has been seriously polluted by such gases, which will threaten people"s living environment. And many accident happened because of the wrong use of such energies. However, such things can"t happen when we use nuclear energy, Though when the nuclear leaks out, it will do great harm to people" s health and the environment. We can do enough work to avoid such things, and limited such things at a low percentage. I believe if we use the nuclear energy in the right way, it will provide us enough energy without doing any harm to us.

　　Nuclear power plants provide about 17 percent of the world"s electricity.Some countries depend more on nuclear power for electricity than others. In France, for instance, about 75 percent of the electricity is generated from nuclear power. There are more than 400 nuclear power plants around the world. 　　To build a nuclear reactor (核反应堆),what you need is some mildly2 enriched uranium(铀). Uranium is a fairly common element on Earth,incorporated3 into the planet during the planet"s formation(形成). U-235 is one of the few materials that can undergo4 induced fission(诱发性核裂变). Raising and lowering the control rods(杆,棒条) allow operators to control the rate of the nuclear reaction.When an operator (操作员) wants the uranium core to produce more heat,the rods are raised out of the uranium bundle(捆,束). To create less heat, the rods are lowered into the uranium bundle.The rods can also be lowered completely into the uranium bundle to shut the reactor down in the case of an accident or to change the fuel. The uranium bundleactsasanextremely high-energy source of heat. It heats the water and turns it to steam. The steam drives a steam turbine(汽轮机), which spins5 a generator(发电机) to produce power. 　　Well-constructed nuclear power plants have an important advantage when it comes to electrical power generation——they are extremely clean. Compared with a coalfired power plant, nuclear power plants are a dream come true from an environmental standpoint (立场,观点). Unfortunately, there are significant problems with nuclear power plants. Mining and purifying(提纯) uranium has not, historically, been a very clean process. Improperly func- tioning nuclear power plants can create big problems. The Chernobyl6 disaster is a good example.Spent fuel from nuclear power plants is toxic (有毒的) for centuries, and, as yet, there is no safe, permanent(永久的) storage facility for it.

核动力的英文是nuclear power。核动力（英语：Nuclear power，也称原子能）是利用可控核反应来获取能量，从而得到动力、热量和电能。产生核电的工厂被称作核电站，将核能转化为电能的装置包括反应堆和汽轮发电机组。核能在反应堆中被转化为热能，热能将水变为蒸汽推动汽轮发电机组发电。因为核辐射问题和现在人类还只能控制核裂变，所以核能尚未得到所有国家、民众的认可，在大部分的国家暂时未有大规模的利用。利用核反应来获取能量的原理是：当裂变材料在受人为控制的条件下发生核裂变时，核能就会以热的形式被释放出来，这些热量会被用来驱动蒸汽机。蒸汽机可以直接提供动力，也可以连接发电机来产生电能。世界各国军队中的某些潜艇及航空母舰以核能为动力。核动力是利用可控核反应来获取能量，从而得到动力，热量和电能。因为核辐射问题和现在人类还只能控制核裂变，所以核能暂时未能得到大规模的利用。利用核反应来获取能量的原理是：当裂变材料在受人为控制的条件下发生核裂变时，核能就会以热的形式被释放出来，这些热量会被用来驱动蒸汽机。蒸汽机可以直接提供动力，也可以连接发电机来产生电能。来源铀是一种常见的化学元素，陆地上和海洋中的每个地方都存在着铀。它就跟锡一样常见，储量比金高500倍。大部分种类的岩石和土壤都包含着铀，尽管浓度极低。比较经济的铀储藏地的铀浓度至少为0.1%。以花费速度来算，地球上可被提取的铀还可用50年。将铀的价格提高一倍对核电站的运行成本不会有什么影响，但可以使地球上可被提取的铀能持续使用几百年。在这种情况下，将铀的价格提高一倍会将核电站的运行成本提高5%。但是，如果将天然气的价格提高一倍，那么天然气的供应成本会提高60%。

Why We Should Use Nuclear EnergyThe growth of nuclear energy in the United States suffered a double whammy in 1979 with the almost simultaneous occurrence of the Three Mile Island accident and the release of the movie The China Syndrome.The Three Mile Island accident, which is most significant accident in the nuclear power industry in the United States, in retrospect was a very minor incident that resulted in zero deaths or injuries. However, it was used by anti nuclear activists to basically kill off any new nuclear plants in this country.Jane Fonda, the star of The China Syndrome, used the incident to campaign against nuclear power and promote her movie. Most of the opposition to nuclear power comes from irrational fear, a fear that is fed by those opposed to nuclear power.Many people who formerly were opposed to nuclear power are now strong supporters of it. Among these people are:Patrick Moore, a co founder of Greenpeace, who stated in a September 2006 appearance before the U.S. House of Representatives, Subcommittee on Energy and Water Development:In the early 1970s, I believed that nuclear energy was synonymous with nuclear holocaust, as did most of my Greenpeace compatriots.That"s the conviction that inspired Greenpeace"s first voyage across the North Pacific coast to protest the testing of U.S. hydrogen bombs in Alaska"s Aleutian Islands.But a lot has changed in the 35 years since then, and my views have changed along with these new circumstances.As a co-chair of the Clean and Safe Energy Coalition along with Gov. Christy Todd Whitman, I make it known often that I strongly believe the rest of the environmental movement needs to update its views, too, because now—more than ever before—nuclear energy is the electricity source that can save our planet from another possible disaster: potentially harmful climate change.James Lovelock, known for proposing the Gaia hypothesis, in which he postulates that the Earth functions as a kind of superorganism. Lovelock states:“The important and overriding consideration is time; we have nuclear power now, and new nuclear building should be started immediately. All of the alternatives, including fusion energy, require decades of development before they can be employed on a scale that would significantly reduce emissions. In the next few years, renewables will add an increment of emission-free energy, mainly from wind, but it is quite small when compared with the nuclear potential.”Stewart Brand, founder, publisher, and editor of The Whole Earth Catalog. Brand states:“Now we come to the most profound environmental problem of all … global climate change. Its effect on natural systems and on civilization will be a universal permanent disaster. … So everything must be done to increase energy efficiency and decarbonize energy production. Kyoto accords, radical conservation in energy transmission and use, wind energy, solar energy, passive solar, hydroelectric energy, biomass, the whole gamut. But add them all up and it"s still only a fraction of enough. … The only technology ready to fill the gap and stop the carbon dioxide loading of the atmosphere is nuclear power. … It also has advantages besides the overwhelming one of being atmospherically clean. The industry is mature, with a half-century of experience and ever improved engineering behind it. … Nuclear power plants are very high yield, with low-cost fuel. Finally, they offer the best avenue to a ‘hydrogen economy," combining high energy and high heat in one place for optimal hydrogen generation.”Much is always made about the issue of nuclear waste and what to do with it.The United States only generates about 20% of its electricity from nuclear. Here is a sample of the percentage of electricity generated by nuclear power in other countries:Country PercentFrance 76.8Lithuania 64.4Slovakia 54.3Belgium 54.0Ukraine 48.1Sweden 46.1Armenia 43.5Slovenia 41.6Switzerland 40.0So why don"t these countries have a problem of nuclear waste storage larger than the US? It is because they recycle their nuclear waste. Something that was banned in the US during the Carter Administration. The ban has since been lifted, but US policy still opposes recycling.About 95% of nuclear waste can be recycled and reused. Using recycling, France estimates that all the nuclear waste generated to provide electricity for a family of four, for 20 years, can be stored harmlessly in a glass cylinder the size of a cigarette lighter.Here are some more facts about nuclear energy from the Clean and Safe Energy Coalition:Nuclear energy is:CleanNuclear energy is an environmentally clean option to produce electricity choice – it produces no harmful greenhouse gases suspected to cause global warming and no gases that could cause ground-level ozone formation, smog or acid rain.Nuclear already accounts for 73 percent of the nation"s emission-free electricity generation and needs be used in compliment with other renewables. Alternative renewable energy sources are important, but can only take us so far – wind and solar can be unreliable and geothermal power isn"t well-suited for all applications. The other major sources of emission-free electricity are hydroelectric plants, which provide 6.6 percent of our nation"s electricity; wind energy, 0.4 percent; and solar energy, 0.01 percent.Safe and SecureNuclear energy is a safe choice. For example, you would have to live near a nuclear power plant for more than 2,000 years to get the same amount of radiation exposure that you receive from a single diagnostic medical x-ray.Nuclear energy is secure. A two-day national security simulation in Washington, D.C., in 2002 conducted by the Center for Strategic and International Studies (CSIS) concluded nuclear plants “are probably our best defended targets,” with the industry spending $1.2 billion in security since September 11, 2001.Affordable and Reliable With rising energy costs a concern for every American, nuclear energy is an affordable and reliable economic choice for electricity. Nuclear power has the lowest production cost of the major sources of electricity. Nuclear plants are the most efficient on the electricity grid and their costs are more predictable than many other energy sources.Economically BeneficialNuclear energy brings economic benefits. From new jobs around new plants to adding $500 million a year to the economy for each new plant brought on line, nuclear plants bring significant economic benefits. Additionally, employees at the plant earn an average of 36 percent more than average earnings in the surrounding communities, so the jobs are high-paying. Perhaps that is why an opinion survey, conducted by Bisconti Research Inc., found that 76 percent of Americans living in close proximity to nuclear power plants are willing to see a new reactor built near them.Nuclear power is a technology that exists now. Nuclear energy can fulfill all of our electrical needs now and into the future. The fuel is readily available in the United States. It is safe and clean. It is recyclable. It is very affordable. In short there is no good reason not to use nuclear power

As human activities become more frequent, the demand for energy is growing. Use of nuclear energy will undoubtedly solve the energy shortage problem, it can provide significant energy and no pollution, making it the 21st century, the most promising new energy However, nuclear energy is a blessing to human beings or disaster? Although the advantages of nuclear energy can not be underestimated, but the number of nuclear leak caused untold sufferings to the people we had to attach importance to 1984 Chernobyl nuclear accident in Ukraine to make tens of millions of local residents were forced to move home, thousands of people because of leakage of radioactive material and infectious cancer, environmental pollution has not yet subsided; recent Japanese nuclear power plant leak, the environment and human health again faced with severe challenges, excessive radiation levels in the air, resulting in a series of food exceeded the amount of radiation; risking human lives with dangerous nuclear radiation. In my opinion, compared with the nuclear energy service brought to mankind, nuclear energy is the human disaster. More resources like solar energy, tidal energy, have greater development potential, do not worry about any pollution, and inexhaustible, do not worry about leaking, do not worry about waste storage.

The sense of doom in us today is not a fear of nuclear power but a fear of war. Nuclear weapons have enlarged the mechanism of war by threatening to kill more people more secretly and more horribly than those of the past. The nightmare of Hiroshima is vivid memory and there is no way to outlaw a war， so the only alternative is to go nuclear in the hope that nuclear weapons hidden in stock somewhere serve to maintain world peace by theory of counter-attack. And yet， going nuclear serves the purpose of energy supply. Now the classic question： "To be or not to be？"

conserve electricityCustomers are asked to conserve electricity between 3 p. m. and 7 p. m. when demand usually peaks.消费者被要求在下午3点-7点的用电高峰期时节约用电。

可再生能源，因为链式反应可以无限进行下去

有区别的

Many country have their own nuclear power station,which has advantages and disadvantages. Before built the nuclear power stations, many countrys can"t provide the enough energy for their people.With the help of nuclear power station,we can get enough energy to do what we like and enjoy everything that we need . It"s also benefical to the country"s economic development. But it also have many disadvantages,if the earthquake disappear where nuclear power station lie in, will produce great disaster which make people suffered the exepected result.Nuclear contamination is a better example ,so we must take it seriously and Completes the measures in advanced as possible as we can. I believe that with the development of technology ,nuclear power station can benefit from people better.

能量的英语可以说：energy拓展：能量，是物质在运动中所具有的量度，是事物运动的本质。它可以区别于物质，是独立于物质的，可以储存在物质中，也可以独立于物质存在于宇宙空间中。能量的概念具有相对性，不同的参考系中，物体的能量可能发生变化。因此，人们对能量做了许多分类和划分，比如机械能、热能、电能、化学能、核能等等。我们生活中常见的能量是热能和动能。热能是物体内部无序运动的能量，是由物体分子间相互碰撞、摩擦等运动所产生的能量。我们热水、汽车发动机、灶台上的火都是热能的体现。动能是物体运动时的能量，是独立于重力势能和位置因素的，它具有质量、速度等物理量决定，常见的有飞机、气球进行的机械运动等。能量在人类社会中也扮演着极其重要的角色，是支撑现代社会建设和经济增长的基础。先进的能源技术可以大大促进人类的生产和生活，为社会的发展提供了强大的动力和保障。现代高速公路、大型机器设备、发热材料，都离不开能源的支持。在如今人类污染、资源匮乏和气候变暖等问题日益严峻的情况下，我们必须采取科学的能源有效利用方式，推进绿色能源技术的开发使用，减少对环境的不良影响。同时，我们也应当逐步掌握能源作为一种战略资源的重要性、敏感性和特殊性，并加强能源的科学管理。现代社会生活中的高水平消耗和能源需求，往往会导致资源短缺、利用过度和环境灾难。为了更好地保护环境、节约能源，我们应该少用一次性的不可再生能源，改用更为可持续性和环保的能源，如太阳能、风能、水能等。

网上查到的(建议):nuclear fuel = 核燃料; a substance that will sustain a fission chain reaction so that it can be used as a source of nuclear energy. [ depleted nuclear fuel = 贫化核燃料; 废核燃料 ( spent nuclear fuel).] uranium =铀; the chemical element of atomic number 92, a gray, dense radioactive metal used as a fuel in nuclear reactors. [ depleted uranium=耗乏铀; 贫化铀; depleted uranium ammunition = 贫化铀弹（贫铀弹）.]

Television must be the most popular pastime for human beings today. Just about every household has a televison set and everyday people glue their eyes on the sets watching their favourite shows. So television exerts a very large influence on us. It is fine if we just use television as a source of entertainment or to be informed about things happening around the world. Programmes such as documentaries are very informative and educating, news keep us up date to the latest developments, while cartoons keep children entertained. However some programmes should be watch under parents guidance such as movies which has violence scenes, nudity scenes or political issues. There is nothing wrong with watching these programmes but they must be done in moderation. We must use television wisely and do not get attached to it. To be addicted or attached to television is to abuse it, that is one feels compelled to have the television on. In other words one becomes a kind of a slave to it and may spend hours just watching it. Only we know whether we are making use of television wisely or are we abusing it. Whichever it is we reap the results of our action.大约意思： 电视可说是人类最普片的消遣。差不多每家每户都有电视。每天人们都会盯着电视看他们喜爱的节目所以电视对我们的影响很大。 倘若我们把电视当成一种娱乐消遣或知道时事的通道是无害的。节目如纪录片是很有教育性质的，新闻能让我们与时事俱进，卡通能娱乐小朋友。但有些电视节目需要父母的监督和引导下观看因为有暴力，色情或政治的话题。 看电视节目是无害但是要适可而止。我们要聪明的选择电视节目，和善于利用时间看电视。不要太依赖电视不然就会染上电视的瘾。换句话说就是成了电视的奴隶，必须要每时每刻看电视。 只有我们自己知道是否我们有善于利用电视。无论那个选择，后果自负（华语表达太差了，我不会把最后一句翻来华文，大约意思就是种什么因就有什么果）华语表达烂。。。。请包涵啊。。。=）

新能源的各种形式都是直接或者间接地来自于太阳或地球内部伸出所产生的热能。包括了太阳能、风能、生物质能、地热能、核聚变能、水能和海洋能以及由可再生能源衍生出来的生物燃料和氢所产生的能量。也可以说，新能源包括各种可再生能源和核能。相对于传统能源，新能源普遍具有污染少、储量大的特点，对于解决当今世界严重的环境污染问题和资源（特别是化石能源）枯竭问题具有重要意义。同时，由于很多新能源分布均匀，对于解决由能源引发的战争也有着重要意义。　　据世界断言，石油，煤矿等资源将加速减少。核能、太阳能即将成为主要能源。 　　联合国开发计划署（UNDP）把新能源分为以下三大类：大中型水电；新可再生能源，包括小水电、太阳能、风能、现代生物质能、地热能、海洋能（潮汐能）；穿透生物质能。　　一般地说，常规能源是指技术上比较成熟且已被大规模利用的能源，而新能源通常是指尚未大规模利用、正在积极研究开发的能源。因此，煤、石油、天然气以及大中型水电都被看作常规能源，而把太阳能、风能、现代生物质能、地热能、海洋能以及核能、氢能等作为新能源。随着技术的进步和可持续发展观念的树立，过去一直被视作垃圾的工业与生活有机废弃物被重新认识，作为一种能源资源化利用的物质而受到深入的研究和开发利用，因此，废弃物的资源化利用也可看作是新能源技术的一种形式。　　新近才被人类开发利用、有待于进一步研究发展的能量资源称为新能源，相对于常规能源而言，在不同的历史时期和科技水平情况下，新能源有不同的内容。当今社会，新能源通常指核能、太阳能、风能、地热能、氢气等。

不可再生.不过想用完几乎也不可能~呵呵

正如京都议定书承诺要在2010年将温室气体的排放减少8%一样，白皮书也旨在2010年内将可再生能源的市场占有率从1995年的6%增加到到12%.绿皮书同时也指出，核能在如今的情况下，不会有更大的发展。这个要归功于能源市场的自由化，还有对比其他能源（例如：天然气），其竞争性地位，公众接受能力和对可能衍生出来的核废料问题的解决方案。在当今的政治局面下，（此部门由指定成员国决定废除）核能的利用在2020年之前可能会有轻微的变动。 运输业对能源的要求增加（到2010要增加50%)和其98%对石油的依赖，这些迫使了我们对可再生能源的更深远的要求，（例如生物燃料）。这些要求具备了很特殊的重要性，因为欧盟现在76%的原油是靠进口，并且这个数据有可能在2010年增加到94%。 对于世界能源市场，欧盟也在推动促进可再生能源的发展上扮演了举足轻重的角色。因为欧盟十分依赖进口能源，在国际市场里，对供需条件的依赖将会列入考虑范围之内。因此，预测的增加65%将会超过20年实现，从2000年的93亿吨，增长到2020年的150亿吨。由于世界人口的增长、发展中国家的需求，这将造成对化石燃料价格的重大影响。因此，有必要通过国际共同的努力来提升可再生能源和可再生能源的利用。 下面就是如今一些提升可再生能源利用的方法。我翻了好久，晚饭都没吃才翻完。希望能帮的到你。

核电站在运行时不能出半点差池。乌克兰的切尔诺贝利核电站的核泄漏事故就是最好不过的前车之鉴。问题是" 人有失手，马有乱蹄"，世界本身不稳定的特性决定了人必然是有失误的时候。我们可以通过诸多努力将这种情况的出现尽可能地减少或推迟，但是做到绝对杜绝人为失误是不可能的。混沌学说揭示了世界的复杂性和不确定性。根据混沌学说的基本原理，系统内充满了对某一事件未来结果具影响力的诸多不可预测和不可认知的因素。我们对所有安全措施的严守都只能是为我们提供一种近似的而非彻底的安全。核电站自身潜在的高危特性是不能允许:作人员有丝毫失误的，这与世界本身的不确定性是严重背离的，因此也就谕示着核电站隐含了不可避免的危险。 核物质高强度的放射性对人体和环境的毁灭性不用赘论了。核能从经济的角度上讲也并非完全可行。人们不了解的是，建一座核电站相对容易，拆除它却要花费数倍乃至十数倍于建造的费用。拆除核电站要将整座核电站用特殊的工具切割成一块一块的小砖头，然后一块一块地用特殊仪器检测，未发现含有过量核辐射的才可以运走。若发现其含有超量核辐射的则要按核废料处理。 提到核废料，极少有人知道它处理的难度，这也是造成公众对核电站抱无所谓态度的主要原因。核废料不同于废电池，统一收集密闭封存就可以高枕无忧了。核废料中不能被完全用尽的核物质仍具有极强的放射性，且具有残留时间长、毒性剧烈的特点。核废料即使贮存过百万年，其残留物质中的核辐射剂量仍能超过允许剂量的一千万倍以上，这是一般人难以想象和理解的。比起核电站的运转来，世界本身所具有的不稳定特性，必将给核废料的安全贮存带来难以预测、不可避免的破坏。基于此，许多原来率先建造核电站的国家正在考虑停建缓建核电站。国外一些专家也呼吁人类在对核能的使用上要慎之又慎。因为核技术不仅是用于军事上才会威胁到人类安全，核技术本身就是极度危险的。

1.it"s efficient, just a small amount of uranium can generage huge amount of energy.2.it"s clean. there is no emission of greenhouse gas,which means it help reduce the effects of global warming.in more technical terms:1.Fissile atoms contain vast amounts of energyNuclear fission, the splitting of a heavy atom"s nucleus, releases great amounts of energy. For example the energy it releases is 10 million times greater than is released by the burning of an atom of fossil fuel. Besides it would take many hectares of land covered with solar collectors, wind farms or hydro-electric dams to equal this power. 2.No greenhouse gases are released by nuclear power plants. According to some, even when accounting for the fossil fuel used in mining uranium, processing it, building and decommissioning of the nuclear plant, the picture remains good from this perspective. Less than one-hundredth of carbon dioxide gas is produced by nuclear power plants compared to coal or gas-fired energy plants. This means nuclear energy also emits less greenhouse gas than renewable energy sources such as hydro, wind, solar and biomass. Ofcourse, others have contrary views to these claims about the advantages of nuclear energy.

　　1、核能不是可再生能源；核燃料是矿产资源，属于非可再生资源；所以核能属于非可再生能源。 　　2、可再生能源(英语:Renewable Energy)为来自大自然的能源，例如太阳能、风力、潮汐能、地热能等，是取之不尽，用之不竭的能源，是相对于会穷尽的不可再生能源的一种能源，对环境无害或危害极小，而且资源分布广泛，适宜就地开发利用。 　　3、核能是人类最具希望的未来能源之一。人们开发核能的途径有两条：一是重元素的裂变，如铀的裂变；二是轻元素的聚变，如氘、氚、锂等。重元素的裂变技术，己得到实际性的应用；而轻元素聚变技术，也正在积极研究之中。

核动力是利用可控核反应来获取能量，从而得到动力热量和电能。

核动力（英语：Nuclear power，也称原子能）是利用可控核反应来获取能量，从而得到动力、热量和电能。产生核电的工厂被称作核电站，将核能转化为电能的装置包括反应堆和汽轮发电机组。核能在反应堆中被转化为热能，热能将水变为蒸汽推动汽轮发电机组发电

Nuclear power stations have been spread everywhere.But their safety has caused a heated discussion about their existance. First,I think that nuclear power stations can provide more electricity than the traditional thermal power stations.They cost less non-renewable resources and produce more electricity.Second,they can push the development of science and technology.Because the nuclear power is a new technology,it can develop fast.Last but not least,nuclear power stations can decrease pollution.Because they rarely produce waste gas and water.Nuclear power stations can benefit us more in the future if government can take safer measures to prevent from accidents.翻译：核电站在世界上分布很广。但是它们的安全性引发了一场关于其是否应该存在激烈讨论。 首先，我认为相比传统热电站，核电站可以提供更多的电能。它们消耗更少的不可再生资源，产出更多的电能。第二，它们可以推动科技的发展。因为核能是一项新技术，它可以发展很迅猛。最后，核电站可以减少污染。因为它们几乎不排放废水废气。 如果政府可以采取更安全的措施来防止事故的话，在不久的将来，核电站会让我们受益匪浅。绝对原创，望采纳，谢谢！！

燃料是铀钍锆等放射性元素，在大剂量的照射下，放射性对人体和动物存在着某种损害作用。如在400rad【拉德（辐射吸收）】的照射下，受照射的人有5%死亡；若照射650rad，则人100%死亡。照射剂量在150rad以下，死亡率为零，但并非无损害作用，往往需经20年以后，一些症状才会表现出来。放射性也能损伤剂量单位遗传物质，主要在于引起基因突变和染色体畸变，使一代甚至几代受害。

1、核动力（英语：Nuclear power，也称原子能）是利用可控核反应来获取能量，从而得到动力、热量和电能。产生核电的工厂被称作核电站，将核能转化为电能的装置包括反应堆和汽轮发电机组。核能在反应堆中被转化为热能，热能将水变为蒸汽推动汽轮发电机组发电。 2、因为核辐射问题和现在人类还只能控制核裂变，所以核能尚未得到所有国家、民众的认可，在大部分的国家暂时未有大规模的利用。利用核反应来获取能量的原理是：当裂变材料（例如铀-235）在受人为控制的条件下发生核裂变时，核能就会以热的形式被释放出来，这些热量会被用来驱动蒸汽机。蒸汽机可以直接提供动力，也可以连接发电机来产生电能。世界各国军队中的某些潜艇及航空母舰以核能为动力（主要是美国）。 3、核动力是利用可控核反应来获取能量，从而得到动力，热量和电能。因为核辐射问题和现在人类还只能控制核裂变，所以核能暂时未能得到大规模的利用。利用核反应来获取能量的原理是：当裂变材料(例如铀-235)在受人为控制的条件下发生核裂变时，核能就会以热的形式被释放出来，这些热量会被用来驱动蒸汽机。蒸汽机可以直接提供动力，也可以连接发电机来产生电能。世界各国军队中的大部分潜艇及航空母舰都以核能为动力，同时，核能每年提供人类获得的所有能量中的7%，或人类获得的所有电能中的15.7%。

The possibility of increases in the cost of uranium in addition to the cost of greater safety provisions could price nuclear power out of the market.铀价的可能上涨加上更好的安全措施的成本可能事核能的成本过高而无人问津。 In the long run, environmentalists argue, nuclear energy may bring about the destruction of the human race. 环境工作者争论道，从长远来看，核能可能给人类带来毁灭性的伤害。Thus, if we wish to survive, we cannot afford nuclear energy.因此，如果我们想存活，我们不能提供核能 In spite of the case against nuclear energy outlined above, nuclear energy programmers are expanding. 尽管存在上述反对核能的言论，核能项目依然正在扩张Such an expansion assumes a continual growth in industrial production and consumer demands.这样的扩张是以工业生产和消费需求的持续增长为假设的 However, it is doubtful whether this growth will or can continue. 但是，这种增长能不能、会不会持续是不确定的。Having weighed up the arguments on both sides, it seems there are good economic and ecological reasons for sources of energy other than nuclear power.在权衡双方的争论后，可以看出，有非常好的经济和生态方面的原因去寻找不同于核能的能源。63选B64 D65 没有前面的文章，我无法判断希望对你有帮助

核动力就是用核能推动潜艇的动力装置，目前大多使用的是压水型核反应堆，整个流程原理是：由核反应堆中的铀一235核燃料进行链式核反应并产生高温，高温把核反应堆内密闭循环的纯净水“煮开”变为蒸汽后，经喷嘴加速变为蒸汽流推动汽轮机运转。汽轮机的转速经过减速齿轮减速后带动螺旋桨。能量转换全过程大致为：核能热能机械能动能。

Prudent to promote development and utilization of nuclear energy. Advantages of nuclear energy are recognized the world: nuclear energy is not like coal and oil and other fossil fuels that produce air pollution, not emissions of greenhouse gas carbon dioxide; nuclear stability, efficiency, nuclear fuel, fossil fuel energy density is hundreds of times; in the normal operation, the nuclear power plant on the surrounding radiation dose produced by the public is not a threat to people.In fact, every energy development and utilization are accompanied by risks and drawbacks. In the process of development and utilization of nuclear energy, the biggest worry is that the public, artificial or extreme environmental factors may lead to leakage of radioactive material, harmful to the environment and human health. Further improve the use of nuclear energy capacity of human security to prevent potential hazards.

I don"t know is the questioner is how to answer, and each of us look at the question of when the angle is different, but I think it is happy, is happy.一千年前人们的生活因为简单而快乐,他们相互之间的联系需要通过飞鸽传书,从上海到北京也是跋山涉水,一路艰辛.若是患上了肺炎,便是无药可医只能全家祈福,但是他们不会担心自己的孩子因沉迷网络而耽误学业,不会为核武器扩散而大伤脑筋,更不会为了争抢石油而毁了整个国家人民的安定与幸福.这样的快乐很单纯.A thousand years ago, people"s life because it is simple and happy, the contact between them need by Dove Chuanshu, from Shanghai to Beijing is also an arduous journey, the hard way. If suffering from pneumonia, no medicine can cure only family praying, but they will not worry about their children addicted to online and delay academic, not for the spread of nuclear weapons and big nerve racking, not in order to compete for oil ruined stability and happiness of the people of the whole country. Such a happy is very simple.话虽如此,生活在当今的我们仍然是快乐的.我们的快乐很直接.Nevertheless, we are still living in today"s happy. Our happiness isdirectly.发展至今的医疗技术,几乎可以将生活中所有常见的疾病通通治愈,被延长了寿命的人们,拥有更多的时间去拓展生命、享受生命.生物、化学等自然学科技术发展的突飞猛进,给原本好奇心强烈的人们带去了丰富多彩的精神食粮.人类在探索与发明的同时给自我价值以肯定,人们在享受科技带来的福祉的同时也收获着快乐.Since the development of medical technology, almost will be all of life common disease Tongtong cure, was extended life of the people, have more time to extend life, enjoy life. Biological and chemical science and technology development by leaps and bounds, to the original curiosity strong people to rich and colorful spiritual food. Human exploration and innovation at the same time to self value to be sure, the people in the enjoyment of welfare brought by science and technology at the same time also harvest the happiness.人类拥有如此伟大的智慧,发现、创造了那么多的“奇迹”.DNA分子的双螺旋解密,因特网施益于千家万户,第一宇宙速度送航天飞机进入宇宙,克隆技术发展助疾病患者重获新生.Humans have such great wisdom, and create the double helix decryption of so many "miracle" of the DNA molecule, the Internet application benefits to millions of households, the first cosmic speed send the shuttle into the universe, the development of cloning technology to assist disease patients rebirth.科学,让生活更美好.但是与此同时,它又将那么多附加的忧虑与恐慌带入了原本纯粹的生活.这样说并不假,但又实实在在冤枉了科技.让人们对科技的感情变得复杂的并不见得就是科技本身,而是去选择如何运用它的人.Science for a better life. But at the same time, it will be so much additional anxiety and panic into the original pure life. To say this is not false, but real wronged technology. Let the people of science and technology of the feelings become complex is not the technology itself, and is to choose how to use it.科技是一门永无止境的学科,它的发展是无法用简单的好坏去评判的.它可以挽救人类,那么它也同样可以毁灭生灵.当爱因斯坦研究出核能量,欲将其运用于宇宙科学研究的同时,法西斯那边已经有人在苦思冥想该怎样将这种技术运用于战争了.就核技术本身而言是无所谓好与坏的,但由于它而在世界上引发出来的争端,使得整个世界上国家间的关系少了一份融洽.就拿二十世纪八十年代的美苏冷战来讲,在反导条约签订之前,整个世界都为之紧绷着神经,一颗导弹的爆炸,毁灭的是一个城市、一个国家,更是千年积淀下来的人类文明.但是人类对核能的恐慌与紧张是完全可以避免的,核能本身一点也不可怕,甚而至于它可以帮助人类缓解甚至解决能源危机,它能作为一门辅助学科,成为其它领域里重要的研究工具.只要没有人动邪念,一切科学技术都将是美好的,它们都将有助于世界的和平与和谐发展.照这么看来,为什么我们还会担心机器人技术的进步和克隆技术的突破呢?科技是一门永无止境的学科,它的发展是无法用简单的好坏去评判的.它可以挽救人类,那么它也同样可以毁灭生灵.当爱因斯坦研究出核能量,欲将其运用于宇宙科学研究的同时,法西斯那边已经有人在苦思冥想该怎样将这种技术运用于战争了.就核技术本身而言是无所谓好与坏的,但由于它而在世界上引发出来的争端,使得整个世界上国家间的关系少了一份融洽.就拿二十世纪八十年代的美苏冷战来讲,在反导条约签订之前,整个世界都为之紧绷着神经,一颗导弹的爆炸,毁灭的是一个城市、一个国家,更是千年积淀下来的人类文明.但是人类对核能的恐慌与紧张是完全可以避免的,核能本身一点也不可怕,甚而至于它可以帮助人类缓解甚至解决能源危机,它能作为一门辅助学科,成为其它领域里重要的研究工具.只要没有人动邪念,一切科学技术都将是美好的,它们都将有助于世界的和平与 Harmonious development. So, why do wehave to worry about the progress of robot technology and the breakthrough of cloning technology?科学,之所以能使生活更美好,是因为有一批又一批合理使用科学技术的善良人们.他们将美丽的科技运用于对社会和谐的建设、对人类物质及精神的丰富与塑造、对真理永不停息地正确的追求.Science, the reason can make our life more beautiful, because there is another batch of rational use of science and technology to the good people of. They will beautiful technology using in to harmonious society construction, rich and shaping of human material and spiritual, pursuit of truth will never cease to correct.当有人提问你,是觉得生活在什么时期的人更快乐的时候,请不要犹豫地告诉他,现在.因为你将用你自己的力量,去约束自己并影响他人,使科学让生活更美好.When someone ask you is feel happier people living in what period of time, please don"t hesitate to tell him now. Because you will use your own power, to restrain themselves and others, make science for a better life.我们也有理由相信,科学技术的迅猛发展将百分百用于造福人类、造福自然、造福世界,让科学绽放最美丽、最纯粹的光彩!We also have reason to believe, the rapid development of science and technology will be 100 percent for for the benefit of mankind, for the benefit of the natural, for the benefit of the world, make scientific bloom the most beautiful, the most pure brilliance.

核燃料肯定会用完的

He infected the flu, didn"t he?译文1： 许多国家用核能来发电译文2：你可以这样来解决这个问题。

2014年6月四级翻译 　　翻译一： 　　为了促进教育公平，中国已经投入360亿元，用于改善农村地区教育设施和加强中西部地区农村义务教育(compulsory education)。这些资金用于改善教学设施、购买书籍，使16万多所中小学收益。资金还用于购置音乐和绘画器材。现在农村和山区的儿童可以与沿海城市的儿童一样上音乐和绘画课。一些为接受更好教育而转往城市上学的学生如今又回到了本地农村学校就读。 　　知识点分析： 　　1、 为了促进：“为了”除了in order to之外还可以用for/for the purpose of，还可以将这部分放在句尾to promote......“促进”除了可以用promote,还可以用further/boost。 　　2、公平：这里姚明名词形式，equal是形容词，名词形式为equality，或是equity。 　　3、360亿元，十亿是billion，即36 billion。后面billion不需要用复数。更不能写360000000（后面不知道多少个0） 　　4、教育设施：educational facilities 　　5、使.....受益：be beneficial to或者直接用动词benefit，并且“使16万多所中小学收益”这句可以用定语从句加以修饰。 　　6、山区：mountainous areas，沿海城市：coast是海岸，所以沿海城市翻译成coastal cities 　　7、转往：transfer，或者用更简单的词语“go to”都可以，翻译只要做到达意，顺畅便可，在句式没有问题的情况下，词语可以低端化。 　　参考译文： 　　In order to promote equality in education, China has invested 36 billion Yuan to improve educational facilities in rural areas and strengthen rural compulsory education in Midwest areas. These funds are used to improve teaching facilities, and purchase books, which benefit more than 160,000 primary and secondary schools. Funds are used to purchase musical instrument and painting tools as well. Now children in rural and mountainous areas can have music and painting lessons just like children from coastal cities. Some students who have transferred to city schools to receive a better education are now moving back to their local rural schools. 　　翻译二： 　　中国教育工作者早就认识到读书对于国家的重要意义。有些教育工作者2003年就建议设立全民读书日。他们强调，人们应当读好书，尤其是经典著作，通过阅读，人们能更好地学会感恩、有责任心和与人合作，而教育的目的正是要培养这些基本素质。阅读对于中小学生尤为重要，假如他们没有在这个关键时期培养阅读的兴趣，以后要养成阅读的习惯就很难了。 　　知识点分析： 　　1、重要意义：直接翻译重要性即可，所以可以翻译成importance。 　　2、经典著作：classic works。 　　3、感恩：grateful，或者thankful也是可以的，学会同义替换。 　　4、基本素质：素质就是人的品德，能力，所以可以翻译成quality，capability。 　　5、关键时期：这里的关键除了翻成important之外，key/critical/crucial都是对的。 　　6、养成习惯：form或者develop都可以表示养成。这一篇翻译相对来说是难度不大，句式把握住，就不会有太大的问题。 　　参考译文： 　　China"s education workers have realized for a long time the importance of reading to the country. Some of them have suggested that a National Reading Day be set up since 2003. They stressed that people should read good books, especially the classic works. Through reading, people can better learn to be grateful, responsible and cooperate with others. However, the purpose of education is to cultivate these basic qualities. Reading is particularly important for primary and middle school students. If they don"t develop the interest of reading during this crucial period, it is difficult to form the habit of reading later. 　　翻译三： 　　中国应进一步发展核能，因为核电目前只占其总发电量的2%，该比例在所有核国家中居第30位，几乎是最低的。 　　2011年3月日本核电站事故后，中国的核能开发停了下来，终止审批新的核电站，并开展全国性的核安全检查。到2012年10月，审批才又谨慎地恢复。 　　随着技术和安全措施的改进，发生核事故的可能性完全可以降低到最低程度。换句话说，核能是可以完全开发和利用的。 　　知识点分析： 　　这篇难度相对比较大，首先一来 核能 这个词语就把学生整懵了。但是其实这个词语不仅是在日常新闻报道还是以前高中课文之中，甚至是前一年四级考试的图画作文之中都出现过。而碰到其他难的词语的时候，就假设把这些词语要解释给小学生听，这样翻译了一遍中文之后，这个中文就会很简单，再翻译成英文就会相对容易： 　　核能：nuclear power或者nuclear energy核电站：nuclear power plants，这里把plant替换成station同样可以发电量:the total generating capacity终止审批：suspend the approvals，终止也可以用terminate,再或者用stop也可以，只是相对于其他两个stop还不够正式。安全检查:safety inspection利用：utilize或者use 　　China should further develope nuclear energy, because nuclear power currently accounts for only 2% of the total generating capacity. The proportion is in 30th among all nuclear-capable countries, which almost the lowest。 　　In March 2011, after the accident of Japanese nuclear power station, China stopped its nuclear energy development, with approvals for new nuclear power plants suspended, and national nuclear safety inspection carried out. Examine and Approval has been restored carefully since October, 2012. 　　With the improvement of technology and safety measures, the possibility of nuclear accidents can be dropped to a minimum extent. In other words, the nuclear energy can be exploited and utilized safely.

核物理专业对英语口语的要求不太高，只要你会说一些专业的用英语就可以口语简简单单的会说一些就可以了

With the fast development of our society, life-long learning has become very important for everyone. This is because one needs lo acquire new knowledge continuously in order to meet the needs of his work.There are several ways for one to learn life-long. One way is to take a part-time education program. That means, one is studying part time while he is working. The program could be at undergraduate level or graduate level. The second way is to study by yourself. You can learn whatever you need for your work on your own. You can learn from books, from TV programs or from radio.I think that life-long learning is very necessary to us. We can choose either of the two ways mentioned above, It depends on your personal preference and interest. I prefer the first one because this kind of learning is systematic and formal. With the help of the teachers, it is easier to learn and quicker to get what you need for your work..There is no doubt that English is one of the world"s most widely used languages. People use a language in one of three ways: as a native language, as a second language, or as a foreign languge. English is spoken as a native language by over three handred million people in the United States, Britain, Australia, New Zealand, Canada, some caribbean countries and South Africa. As a second language, English is often necessary for official business, education, information and other activities in many countries, it is one of the few "working" languages of the United Nations. It is said that English has become the language of international trade and transport. Most pilots in planes travelling from one country to another use it to talk with airports. All ships sailing on the oceans call for help by radio in it. It has been said that 60 percent of the world"s radio broad casts and 70 percent of the world"s mail uses English. At international sports meets, and international of scientists English is the language most commonly used and the most widely used. English has in fact become the language of international cooperation is science and technology. The most advanced resuits in space, nuclear and computer research are published in it. A scientist who speaks and writes English is in closer touch with the scientists in other countries than one who doesn"t.英语的重要性 毫无疑问，英语是世界上使用最广泛的语言之一。人们使用语言无非有二种情况：作为母语，作为第一语言，再就是作为一门外语。英语，作为母语，有3亿多人在使用。他们分别在美国、英国、澳大利业、新西兰、加拿大还有一些加勒比海国家及南非等。作为第一语言，英语在很多国家的官方事务、教育、信息和其他活动中都是必不可少的。它是联合国仅用的几种工作语言之一。 人们说英语已经成为国际商贸和交通运输语言。大部分飞行于各国间的飞行员使用英语来与飞机场联络。在大洋上航行的轮船都用英语发出求救信号。据说世界上百分之六十的无线电广播和百分之七十的邮递业务用的是英语。在国际体育比赛中和国际科学家大会上，英语使用得最多也最为广泛。 事实上，英语已成为国际科学技术合作的通用语。太空、核能及计算机方面最先进的研究成果都用英语来发表。会用英语交谈和写作的科学家比不会使用英语的科学家，与其他国家的同行们联系要密切得多。The importance of learning English English is the most widely used language in the world. Therefore, having great English skills will have numerous advantages. Luckily, I have realized the importance of learning English and worked hard on it since I was a child. However, 13 years of learning English experience didn"t lead me to success, but being a person who can hardly communicate in English and definitely unable to write an essay. Once I came to the USA, I knew that I had made too many mistakes in learning English. Those mistakes are translating English into different languages, don"t learn vocabulary as much as I can, and don"t read and write enough. First of all, every language is unique. They usually have different grammar and use of vocabulary, which means learning English by translating it into different languages will lead to an inevitable defeat. For example, I have worked hard on learning a lot of vocabulary by translating them into Chinese. I thought it was a good idea to build up my vocabulary in order to read and write better. However, those translation processes were hugely disappointing. At that time, I failed to express my idea accurately by those translated vocabulary. As a consequence, good grade and improvement seemed untouchable. Also, when I either wrote or read, I had to use Chinese to think about the passage. As a result, I didn"t do it well and did it very slowly. When I came to the USA, I desperately and completely stopped translation. Just a year of time, my English was obviously and generally improved. I attribute my success to the stop of translation. Second, I would like to show about how best we can utilize our English skills by learning more vocabulary. When I came here, I bought a book about the Second World War. The book is very thick and has too many new words for me. While I started reading, I could only read 5 pages per half an hour. However, I had never been frustrated. Whereas, I worked hard on it and learned 10 new words from it every day. Subsequently, I can probably read 12 pages per half an hour. On the other hand, the vocabulary can also help me in different aspects. Whenever I read a newspaper, a magazine or other books, they help me to understand more about the context. In addition, they also work when I write. They enable me to write in various ways for the same meaning and provide me with more word choices to write accurately. So my essay is generally improved. In my opinion, my reading and writing improvement are partly from the extension of my vocabulary. Finally, I am going to talk about reading and writing. They are undoubtedly the key element to learn English comfortably and effectively. In the past, I put majority of time on doing grammar exercises, but improvement is near invisible. Once I put my heart into reading and writing, I can feel my English is leaping over many steps. On the other side of the coin, let"s talk about soccer. If I just tell you how to control and shot the ball, but don"t give you any chance to practice. Do you think you can still play it well? Improving English from only doing grammar exercises is usually inferior to reading and writing practice. Only practices can help us to react to the reality. Therefore reading and writing are crucial to our English. In conclusion, stopping translation processes, learning more vocabulary, reading more, and writing more are the most effective way or even the only way to improve our English. The advice is invaluable and learnt painfully. If I have learnt them before, my English must be much better than now. Anyway, I hope you guys can pay heed to me and have a good future.这一篇有点长，你可以摘抄其中的几个句子，希望对你有所帮助！
