　　Powering a City? It's a Breeze

　　The graceful wooden windmills that have broken up the flat Dutch landscape for centuries—a national symbol like wooden shoes and tulips—yielded long ago to ungainly metal-pole turbines.

　　Now, windmills are breaking into a new frontier. Though still in its teething stages, the “urban turbine” is a high-tech windmill designed to generate energy from the rooftops of busy citles. Lighter, quieter, and often more efficient than rural counterparts, they take advantage of the extreme turbulence and rapid shifts in direction that characterize urban wind patterns.

　　Prototypes have been successfully tested in several Dutch cities, and the city government in the Hague has recently agreed to begin a large-scale deployment in 2003. Current models cost US$8,000 to US$12,000 and can generate between 3,000 and 7,000 kilowatt hours of electricity per year. a typical Dutch household uses 3,500 kilowatt hours per year, while in the United States, this figure jumps to around 10,000 kilowatt hours.

　　But so far, they are being designed more for public or commercial buildings than for private homes. The smallest of the current models weigh roughly 200 kilograms and can be installed on a roof in a few hours without using a crane.

　　Germany, Finland and Denmark have also been experimenting with the technology, but the ever-practical Dutch are natural pioneers in urban wind power mainly because of the lack of space. The Netherlands, with 16 million people crowded into a country twice the size of Slovenia, is the most densely populated in Europe.

　　Problems remain, however, for example, public safety concerns, and so strict standards should be applied to any potential manufacturers. Vibrations are the main problem in skyscraper-high turbine. People don't know what it would be like to work there, in an office next to one of the big turbines. It might be too hectic.

　　Meanwhile, projects are under way to use minimills to generate power for lifeboats, streetlights, and portable generators. “I think the thing about wind power is that you can use it in a whole range of situations,” said Corin Millais, of the European Wind Energy Association. “It's a very local technology, and you can use it right in you backyard. I don't think anybody wants a nuclear power plant in their backyard.”

　　1. What are the symbols of Netherlands according to the first paragraph?

　　A. The flat landscape.

　　B. Wooden shoes and wooden windmills.

　　C. Metal-pole turbines.

　　D. Both A and B.

　　2. Which statement is best describes the urban turbine mentioned in the second paragraph?

　　A. It is a windmill put on rooftops of buildings for energy generation.

　　B. It is a high-tech machine designed to generate energy for urban people.

　　C. It is light and quiet and therefore more efficient.

　　D. It is driven by urban wind.

　　譯文：

　　風(fēng)力發(fā)電?輕而易舉

　　與木鞋、郁金香一起被視為荷蘭象征的風(fēng)車，在荷蘭平原上優(yōu)雅地矗立了幾個世紀(jì)，可是，它的作用早已為笨拙的金屬渦輪所代替。

　　現(xiàn)在，風(fēng)車已經(jīng)進入了一個新的疆域。雖然還處于萌芽階段，城鎮(zhèn)使用的渦輪機已經(jīng)是一種高科技的風(fēng)車，它們從大城市的平頂房上產(chǎn)生能量。它們利用了城市中的風(fēng)所特有的亂流和快速轉(zhuǎn)向，比起鄉(xiāng)村風(fēng)車來，更輕，更安靜，更有效率。

　　這種風(fēng)車的樣品已經(jīng)成功地在荷蘭的幾個城市得到測試。海牙市政府最近已經(jīng)同意在2003年開始大規(guī)模發(fā)展這種風(fēng)車。目前的風(fēng)車模型大約花費8000到112000美元，每年能夠產(chǎn)生3000到7000千瓦時的電。一個典型的荷蘭家庭每年使用3500千瓦時的電，而在美國，這個數(shù)字則要上千到大約10000千瓦時。

　　但是到目前為止，這些風(fēng)車的設(shè)計更適合于公共或商務(wù)設(shè)施，而不是家庭。目前最小的風(fēng)車模型大約有200公斤重，而且不需要吊車就可以將它安裝在屋頂。

　　德國、芬蘭和丹麥都已經(jīng)開始這項技術(shù)的實驗，但是，荷蘭的空間狹小使得它在城市風(fēng)力發(fā)電上始終是最實際的先驅(qū)。荷蘭擁有1600萬的人口，是斯洛文尼亞的兩倍，是歐洲人口密度的國家。

　　盡管如此，問題仍然存在。比如，公共安全問題，以及對潛在的制造商制定嚴(yán)格的標(biāo)準(zhǔn)。高聳入云的渦輪機最主要的問題是振動。人們無法想像在一個巨大的渦輪機旁邊的辦公室里如何工作。那一定是鬧哄哄。

　　與此同時，使用小型風(fēng)車為救生船、路燈和便攜式發(fā)電同提供能量的計劃也在進行之中。“我認(rèn)為使用風(fēng)力就是能讓人在任何情況下都可以使用。”歐洲風(fēng)能協(xié)會的CorinMillais說，“這是一種因地制宜的技術(shù)，人們能在自己家的后院使用。我想沒有人希望自己家的后院里是一個核電站。”
