问题     Is nuclear energy better than other energy resources in meeting the ever-increasing needs of the globe? This has been intensely discussed for years. The following are the supporters’ and opponents’ opinions. Read carefully the opinions from both sides and write your response in about 200 words, in which you should first summarize briefly the opinions from both sides and then give your view on the issue.

    Yes:
    Nuclear energy by far has the smallest impact on the environment since it does not release any gases like carbon dioxide or methane which are largely responsible for greenhouse effect.
    Nuclear energy is more powerful and efficient than other alternative energy resources. Advancement of technology has made it a more viable option than other energy resources.
    Unlike traditional energy resources like solar energy and wind energy which require sun or wind to produce electricity, nuclear energy can be produced from nuclear power plants even in the case of unfavorable weather conditions.
    No:
    The waste produced by nuclear reactors needs to be disposed of in a safe place since it is extremely hazardous and can release radiation if not stored properly.
    While so many new technologies have been put in place to make sure that nuclear accidents won’t happen again like what happened in Chernobyl, the risk associated with nuclear energy is still relatively high.
    There are power reactors called breeders, which produce plutonium. It is an element that is not found in nature. It is a by-product of the chain reaction and is very harmful if introduced in to nature.

答案 Is Nuclear Energy Better than Other Energy Resources? As the world’s demand for energy continues to rise, nuclear energy begins to play an increasingly important part in solving that issue. It is considered as the worthiest alternative energy for its lower greenhouse gas emission, high efficiency and reliability when compared with traditional energy resources. But the use of nuclear energy has also met with fierce opposition for its intractable radioactive waste, disastrous nuclear accidents and fearsome nuclear radiation. In my view, the nuclear option at the moment is better than other energy resources. First of all, nuclear energy is of low cost because its production requires less raw materials and the expense of running a nuclear power plant is rather low, even though the cost of establishing one is fairly high. Secondly, since producing nuclear energy only requires little amount of uranium, its transportation is much easier than fossil fuels. Lastly, this energy has a continuous supply. With huge reserves, its supply is believed to last much longer than that of fossil fuels. In brief, there are certain advantages of using nuclear energy in place of conventional energy resources. Nevertheless, the difficulty in disposing of radioactive waste is still its big drawback. Hence, international cooperation is required to make sure nuclear energy is developed in strict adherence to the relevant safety standards.
解析     本题讨论的是与其他能源相比，核能是否能更好地满足全球日益增长的能源需求。在具体行文方面，考生应首先概述正反双方的观点。然后给出自己的观点：目前核能要比其他能源更好。最后总结全文。
    开头部分阐述背景并概述正反双方的观点。正方观点：与其他能源相比，核能具有更低的温室气体排放、高效并且可靠等优势。反方观点：核能的使用遭到了强烈的反对，因为它会产生棘手的放射性废弃物，并导致灾难性的核事故以及可怕的核辐射。
    中间部分通过“In my view…”提出自己的观点：目前核能要比其他能源更好。并用“First of all…” “Secondly…”和“Lastly…”阐述理由：核能的成本低，这是因为生产核能只需要非常少量的原材料，并且核电站的运行成本也相对较低；由于生产核能只需要少量的铀，其运输要比化石燃料容易得多；由于储量大，核能可以源源不断地供应，其供应时间要远超化石燃料。
    结尾部分通过“In brief…”总结全文，并提出建议。
