參考范文
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
核電站為我們提供了全球大約17%的電力資源。全世界目前投入使用的核電站超過了400座。以法國為例，該國75%的電力來自核電。很多國家越來越依賴核能發(fā)電。
一些人認為，核能是滿足日益增長的能源需求的非常好的選擇。經(jīng)濟與社會的飛速發(fā)展以及人口的膨脹，這些都對資源的供應造成了巨大的負擔。在這樣的條件下，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。但另一些人則反對使用核能，因為他們認為核能可能會對人體健康和環(huán)境造成不可挽回的傷害，而且一旦發(fā)生意外，那將會是人類的悲劇。2011年發(fā)生的日本核危機一定程度上印證了他們的擔憂。
對我而言，我支持核能的使用。首先，核能幾乎不會造成傳統(tǒng)的空氣污染，可被稱作“清潔能源”。其次，科技的發(fā)展也為科學規(guī)避自然災難之類風險提供了幫助。最后，與其他傳統(tǒng)能源，諸如太陽能，風能，潮汐等相比，核能是最好的選擇，可解決煤炭和天然氣的短缺問題。

句法點評
1. Once the unexpected situation happens, it may cause a tragedy to human beings.
once引導狀語從句，表示條件，意為“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.
過去分詞短語compared with other energies like solar energy, wind energy and tidal energy作狀語，表被動。
