Question

Last night’s meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothsclild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.

 “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment. ”

       Astronomers—scientists who study stars and planets—-have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.

 There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(遷徙的)birds. According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers. ”

 Countless more animals casualties(傷亡）result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer.

        Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff,Arizona,has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.

1.D

2.B

3.C

【解析】

試題分析：本文敘述了戶(hù)外照明的危害。戶(hù)外照明不僅影響天文學(xué)家的觀測(cè)，還影響了動(dòng)物的遷徙，對(duì)動(dòng)物的生活是一種威脅�？茖W(xué)家還說(shuō)照明對(duì)人體有害，易導(dǎo)致癌癥。因此人們開(kāi)始采取措施，實(shí)施一些光照條例，能過(guò)讓人與動(dòng)物共同享受夜晚。

1.推理判斷題。根據(jù)第四段的This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(遷徙的)birds.可知戶(hù)外照明已經(jīng)影響了動(dòng)物的遷徙，對(duì)動(dòng)物的生活是一種威脅。故選D。

2.推理判斷題。根據(jù)最后一段的For years, Flagstaff,Arizona,has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.可知美國(guó)亞利桑那州的弗拉格斯塔夫市為了幫助天文學(xué)家在洛厄爾天文臺(tái)的觀測(cè)，執(zhí)行了照明條例。從中看沖這樣是為了創(chuàng)造一個(gè)好的觀測(cè)的環(huán)境。故選B。

3.推理判斷題。根據(jù)第五段的Countless more animals casualties(傷亡）result from the use of artificial lighting.可知戶(hù)外照明對(duì)動(dòng)物有危害。根據(jù)最后一段的Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night. 可知人們已經(jīng)意識(shí)到照明的危害，開(kāi)始采取措施。因此可概括為本文是想告訴我們?nèi)祟?lèi)的活動(dòng)要環(huán)保。故選C。

考點(diǎn)：科普環(huán)保類(lèi)短文閱讀。
