　　核电站的一次性投资确实比火电站大一些。衡量电站的经济价值，还要核算电站运行后消耗的燃料、设备折旧、运行管理等费用。30年来，国际上对煤电成本与核电成本所作的等值比较，显示出修火电站实际出现的低投入经济效应的负走向，修建核电站则正相反。目前，已有几十个国家建成300余座核电站，总功率达2亿千瓦左右，绝大多数核电站已使核电成本降至煤电的60%左右。现代经济价值观取得了又一次胜利。

　　至于核电站所出现的事故，不足以否定其安全性。从核反应形式看，原子弹可以和核电站类比，但原子弹所用的铀-225浓度在弹体中高达90%，因此造成核链式反应的不可控性；而核电站采用的燃料是浓度低于4%的铀-235，这样反应效应就与原子弹有有根本的区别。从实际情况看，任何形式的电站，只要设计、管理出了问题，都可能导致事故发生。1979年印度一座大坝水电站爆炸竟使1.5万人丧生，当然这不是说切尔诺贝利核电站核物质外泄夺走了人的生命就值得庆幸。值得庆幸的是核电站系统工程技术有了新突破，核电站安全保险系数优于火电站。说到环境保护，最先进的火电站也难以让人作乐观的承诺，而核电站则别具优势。

文中“低投入经济效应的负走向”是指（）。

A．低投入势必造成高成本

B．低投入造成的成本逐渐增加的趋势

C．煤电成本低的优势难以持久

D．煤电成本高于核电成本

     Driving to a friend's house on a recent evening, I was attracted by the sight of the full moon rising just

above my friend's rooftops. I stopped to watch it for a few moments, thinking about what a pity it was

that most city people, myself included, usually miss sights like this because we spend most of our lives

indoors.

     My friend had also seen it. He grew up living in a forest in Europe, and the moon meant a lot to him

then. It had touched much of his life.

     I know the feeling. Last December I took my seven-year-old daughter to the mountainous jungle of

northern India with some friends. We stayed in a forest rest-house with no electricity or running hot water. Our group had campfires outside every night, and indoors when it was too cold outside. The moon grew

to its fullest during our trip. Between me and the high mountains lay three or four valleys. Not a light shone

in them and not a sound could be heard. It was one of the quietest places I have ever known, a bottomless well of silence. And above me was the full moon, which struck me deeply.   

     Today our lives are filled with glass, metal, plastic and fibre-glass. We have televisions, cell phones,

pagers, electricity, heaters and ovens and air-conditioners, cars, computers.

     Struggling through traffic that evening at the end of a tiring day, most of it spent indoors, I thought:

before long, I would like to live in a small cottage. There I will grow vegetables and read books and walk

in the mountains And perhaps write, but not in anger. I may become an old man there, and wear the

bottoms of my trousers rolled and measure out my life in coffee spoons. But I will be able to walk outside on a cold silent night and touch the moon.
