In both modern and ancient thinking, light and brightness are viewed positively. _(1)_
The ideal situation for any astronomer 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 both amateur and professional astronomers. Even the Royal Observatory in Greenwich, England, has been affected. _(3)_
An amateur astronomer in the US became so frustrated with light pollution that she decided 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. _(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 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 to science.
(C) The IDA also advises governments, cities, and companies on how they can light outdoor areas with minimal 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.

a.advise sb on sth 就某事給予某人建議,就某事提供某人意見
例: My accountant always advises me on how to invest my money.
(我的會計師總會給我投資方面的建議。)

中文翻譯&標準答案
無論古代或現代,都對光和明亮抱持正面的想法。然而,太多光線卻會妨礙科學。
對任何天文學家來說,最理想的狀況是觀察天空時沒有任何人造光線的阻礙。在充斥著街燈與霓虹燈招牌的現代世界中,這幾乎是不可能的事。在人口密布的地區(qū)過度使用光線造成所謂『天空輝光』的現象。天空輝光會降低明暗對比的可見度。對天文學家來說,在深邃宇宙中看見由星星、星球和其它物體反射的光線是很重要的。這些困擾讓業(yè)余和專業(yè)天文學家感到很挫敗。就連英國的格林威治天文臺都受到影響。因光害限制了天文臺所做的觀測,因此必須遷移臺址。
一名美國業(yè)余天文學家因光害問題感到很沮喪,因此決定發(fā)起一年一周不開燈保持暗黑天空的活動。雖然她當時只是一名中學生,仍設法架設網站喚起大眾的認知。她的努力最后促使『暗天周』在 2003 年四月首次實行。
暗天周是由國際暗天協(xié)會協(xié)辦。該協(xié)會致力于減少光害逾二十年。國際暗天協(xié)會也提供意見給全球政府、城市與公司行號,如何在產生最少量的天空輝光下照亮戶外的方法。探討光害問題不僅對天文學家有幫助,也對全球人口有益。有越來越多證據顯示光害也會導致健康問題。
在星光熠熠的夜晚,當我們抬頭朝北極星和其它肉眼可見的星星望去之際,還必須運用想象力。因為宇宙中還有數百萬個星體,只要關上燈,我們就能親眼目睹。
