Light pollution
We usually think of pollution as a harmful waste substance that threatens the air and water．But some people have become concerned about another kind of pollution．It can be everywhere，depending oil the time of day．And it is not thought of as a substance．It is light．
The idea of light pollution has developed with the increase of lights in reties．In many areas，this light makes it difficult or impossible to observe stars and planets in the Hiight sky．In l988，the International Dark—Sky Associations formed．This organization wants to reduce light pollution in the night sky．It also urges the effective use of electric lighting．
There are a number of reasons why reducing light pollution is important．One has become clear at the Mount Wilson Obsmvatory near Los Angels，California．Mount Wilson Observatory was home to the largest telescopes in the world during the first half of the l900s．
During that period，Los Angeles grew to become one of America’s biggest cities．
Today，light from Los Angeles makes the night sky above Mount Wilson very bright．It is no longer all important research center because of light pollution．
Light pollution threatens to reduce the scientific value of research telescopes in other important observatories．They include Like Observatory near San Jose，California and Yorkers Observatory near Chicago，Illinois．
Light pollution is the result of wasted energy．Bright light，that shines into the sky is nol being used to provide light where．it is needed Oil Earth．Poorly designed lighting causes a great deal of light pollution．Lights that are brighter than necessary also cause light pollution．
Recently，two Italian astronomers and an American environmental scientist created a world map of the night sky．
The map shows that North Ameriea，Western Europe and japan have the greatest amount of light pollution．
Most people in America are surprised to find out，that they are able to see our OWn galaxy，the Milky Way，with their own eyes．But about three—fourths of Americans cannot see the Milk),Way because of man—made light．
Objects in the night sky are resources that provide everyone with wonder．But light pollution threatens to prevent those wonderful sights from being seen．

2．Light pollution results entirely from the ineffective use of electric lights．
A．Right
B．Wrong
C．Not mentioned
3．Bright light from such big cities as Los Angeles has reduced the scientific value of some important observatories nearby．
A．Right
B．Wrong
C．Not mentioned

1．A．該信息判斷句說“根據(jù)文章內(nèi)容來看，城市里的燈光越來越多，而‘光污染’這個(gè)概念也就隨之出現(xiàn)了．”與該信息判斷句相關(guān)的內(nèi)容出現(xiàn)在第2段的第1句：The idea of light pollution has developed with(與“come with”意義相近)the increase of lights in cities．該句說“城市的燈光越來越多，而‘光污染’這個(gè)概念也就隨之逐漸形成”，因此該信息判斷句提供了正確信息．
2．B．該信息判斷句說“光污染完全是由于沒有有效地利用電燈照明而造成的．”第2段的最后兩句與該信息判斷句的內(nèi)容相關(guān)：This organization wants to reduce light pollution in the night sky．It also urges the effective
use of electric lighting．這兩句話說“這個(gè)組織想要減少夜空中出現(xiàn)的光污染．這個(gè)組織也力勸人們有效地使用電燈照明”．根據(jù)這兩句話的內(nèi)容可以推斷出“造成光污染的一個(gè)原因是人們沒有有效地使用電燈照明”．文章第7段段首句說：Light pollution is the result of wasted energy(能量浪費(fèi)是造成光污染的原因)．由此可知造成光污染的另一個(gè)原因是因?yàn)槟芰坷速M(fèi)．因此光污染至少是由2個(gè)原因造成的，由此判斷該信息判斷句沒有提供正確信息．
3．A．該信息判斷句說“自洛杉磯這種大城市里發(fā)出的明亮燈光已經(jīng)降低了附近一些重要天文臺(tái)的科學(xué)價(jià)值”．與該信息判斷句相關(guān)的內(nèi)容出現(xiàn)在第5段：Today，light from Los Angeles makes the night sky above Mount Wilson very bright．It is no longer an important research center because of light pollution．該段說“來自洛杉磯的燈光使Wilson山頂上的夜空非常明亮，而洛杉磯也因?yàn)楣馕廴径辉谑且粋€(gè)重要的研究中心．”雖然該句中沒有提到天文臺(tái)臺(tái)，但是接下來的句子提到了：Light pollution threatens to reduce the scientific value of research telescopes in other important observatories．該句說“光污染可能會(huì)減少在其它重要天文臺(tái)中使用的研究望遠(yuǎn)鏡的科學(xué)價(jià)值”，根據(jù)該句內(nèi)容可以推斷出在洛杉磯也有天文臺(tái)，它們的科學(xué)價(jià)值也因?yàn)楣馕廴径唤档土耍虼嗽撔畔⑴袛嗑涮峁┝苏_的信息．
4．A．該信息判斷句說“天文學(xué)家創(chuàng)作出的世界夜空?qǐng)D顯示發(fā)達(dá)國家光污染的程度最嚴(yán)重．”與該問題相
關(guān)的內(nèi)容在倒數(shù)第3段：Recently，two Italian astronomers and an American environmental scientist created a woad map of the night sky．The map shows that North America,Western Europe and Japan have the greatest amount of light pollution．劃線句說“美國，西歐和日本光污染最嚴(yán)重”，這些國家都是發(fā)達(dá)國家，因此該信息判斷句提供了正確信息．加入收藏
5．A．該信息判斷句說“最后一段內(nèi)容表明過于明亮的夜空會(huì)剝奪掉我們看見宇宙中神奇自然景象的機(jī)會(huì)”．文章最后一段最后一句說“光污染會(huì)使人們看不見那些神奇的景觀”，而those wonderful sights(那些神奇的景觀)就是回指前句中提到的0bjects in the night sky(夜空中的物體)，因此該信息判斷句提供的內(nèi)容正確．
6．C．該信息判斷句說“空氣污染與光污染造成的危害性的程度相同．”文章中沒有把這兩種污染的危害性進(jìn)行比較，因此只能判定該信息判斷提供的信息在文章中沒有被提到．
7．C．該信息判斷句說“中國的大城市也正遭受到光污染”．China一詞在文章中根本沒有出現(xiàn)，由此可以判斷該信息判斷句提供的信息在文章中沒有被提到．
