常春藤解析英语【17】光害危机
时间:2018-12-08 作者:英语课 分类:常春藤解析英语
by Ilse van Wyk
In both modern and ancient thinking, light and brightness are viewed positively 1. _(1)_
The ideal situation for any astronomer 2 is to be able to observe the sky when there is no interference from artificial light. In the modern world of streetlights and neon signs, this is nearly impossible. The overuse of lights in populated areas causes a phenomenon called skyglow.
_(2)_ For an astronomer, it is vital to see the reflected light from stars, planets, and other objects in deep space. These difficulties frustrate 3 both amateur and professional astronomers 4. Even the Royal Observatory 5 in Greenwich, England, has been affected 6. _(3)_
An amateur astronomer in the US became so frustrated 7 with light pollution that she decided 8 to campaign for one week of dark skies every year. Although she was only a high school student, she managed to set up a website to raise public awareness 9. _(4)_
The National Dark-Sky Week is supported by the International Dark-Sky Association (IDA). This association has aimed to cut down on light pollution for almost 20 years. _(5)_ Addressing the problem of light pollution is helpful not only to astronomers but also to millions worldwide. There is mounting evidence that light pollution may contribute to health problems as well.
On a starry 10 night, when we look up to the North Star and all the others visible to the naked eye, we have to use our imaginations. There are millions of other things in space that we would be able to see if we just turned off the lights.
(A) Her efforts eventually yielded National Dark-Sky Week, which was first held in April 2003.
(B) However, too much light can be a hindrance 11 to science.
(C) The IDA also advises governments, cities, and companies on how they can light outdoor areas with minimal 12 skyglow.
(D) The site of the observatory had to be moved since light pollution limited the observations that could be made.
(E) Skyglow lowers the ability to see the contrast between light and dark.

中文翻译&标准答案
无论古代或现代,都对光和明亮抱持正面的想法。然而,太多光线却会妨碍科学。
对任何天文学家来说,最理想的状况是观察天空时没有任何人造光线的阻碍。在充斥着街灯与霓虹灯招牌的现代世界中,这几乎是不可能的事。在人口密布的地区过度使用光线造成所谓『天空辉光』的现象。天空辉光会降低明暗对比的可见度。对天文学家来说,在深邃宇宙中看见由星星、星球和其它物体反射的光线是很重要的。这些困扰让业余和专业天文学家感到很挫败。就连英国的格林威治天文台都受到影响。因光害限制了天文台所做的观测,因此必须迁移台址。
一名美国业余天文学家因光害问题感到很沮丧,因此决定发起一年一周不开灯保持暗黑天空的活动。虽然她当时只是一名中学生,仍设法架设网站唤起大众的认知。她的努力最后促使『暗天周』在 2003 年四月首次实行。
暗天周是由国际暗天协会协办。该协会致力于减少光害逾二十年。国际暗天协会也提供意见给全球政府、城市与公司行号,如何在产生最少量的天空辉光下照亮户外的方法。探讨光害问题不仅对天文学家有帮助,也对全球人口有益。有越来越多证据显示光害也会导致健康问题。
在星光熠熠的夜晚,当我们抬头朝北极星和其它肉眼可见的星星望去之际,还必须运用想象力。因为宇宙中还有数百万个星体,只要关上灯,我们就能亲眼目睹。
