参考范文
Nuclear energy plants provide about 17 percent of the world’s electricity. More than 400 nuclear energy plants around the world are under use now. In France, for instance, about 75 percent of the electricity is generated from nuclear energy. Many countries increasingly depend on nuclear energy for electricity. 1
Some hold that nuclear energy is a good choice for meeting increasing demand. 2 The rapid development of economy and society as well as the expanded population, causes heavy burden to the resource supply. In these conditions, nuclear energy shows its giant charm in providing energy efficiently and largely. But others are against nuclear energy because they think nuclear energy may be irreversibly harmful to people’s health and environment. 2 Once the unexpected situation happens, it may cause a tragedy to human beings. And the nuclear crisis of 2011 of Japan has supported their concern to some degree.
As for me, I am in favor of using nuclear energy. First, nuclear energy produces nearly no conventional air pollution, which can be called as “clean energy”. 3 Besides, due to advancements in technology, risks such as natural disaster can be avoided scientifically. 3 Last, compared with other energies like solar energy, wind energy and tidal energy, it is the best to solve the shortage of coal and natural gas. 3
核电站为我们提供了全球大约17%的电力资源。全世界目前投入使用的核电站超过了400座。以法国为例，该国75%的电力来自核电。很多国家越来越依赖核能发电。
一些人认为，核能是满足日益增长的能源需求的非常好的选择。经济与社会的飞速发展以及人口的膨胀，这些都对资源的供应造成了巨大的负担。在这样的条件下，核能的使用可以高效且大量地提供能源，展示出了它巨大的魅力。但另一些人则反对使用核能，因为他们认为核能可能会对人体健康和环境造成不可挽回的伤害，而且一旦发生意外，那将会是人类的悲剧。2011年发生的日本核危机一定程度上印证了他们的担忧。
对我而言，我支持核能的使用。首先，核能几乎不会造成传统的空气污染，可被称作“清洁能源”。其次，科技的发展也为科学规避自然灾难之类风险提供了帮助。最后，与其他传统能源，诸如太阳能，风能，潮汐等相比，核能是最好的选择，可解决煤炭和天然气的短缺问题。
范文点评

conventional adj. 传统的
in favor of 赞同；支持
句法点评
1. Once the unexpected situation happens, it may cause a tragedy to human beings.
once引导状语从句，表示条件，意为“一旦……”。
2. Last, compared with other energies like solar energy, wind energy and tidal energy, it is the best to solve the shortage of coal and natural gas.
过去分词短语compared with other energies like solar energy, wind energy and tidal energy作状语，表被动。
