總結(jié)：做閱讀理解時(shí)大家需要牢牢抓住文章的中心或核心詞，只要被選項(xiàng)中有核心內(nèi)容的出現(xiàn)就可以推測為正確答案！

　　4. How does light pollution affect wildlife? Which of the following is NOT correct?

　　A . Animals may go off course due to the attraction of artificial lights

　　由于受到人造光的吸引，動(dòng)物們可能偏離航向．

　　B . Animals might be attracted by artificial lights to go into cities．

　　動(dòng)物們可能會(huì)受到人造光的吸引而進(jìn)入城市

　　C. Artificial lights at night may make migrating birds lose their way．

　　夜間的人造光可能會(huì)使遷徙的鳥類們迷路

　　D Attracted by artificial lights，birds fly into lighted buildings．

　　由于受到人造光的吸引，鳥類飛進(jìn)有光的建筑物里。

　　分析：題目是說：光污染是如何影響野生動(dòng)物？下列哪個(gè)說法不正確？

　　關(guān)鍵詞就是wildlife，在最后一段里，可以找到內(nèi)容：

　　Light pollution doesn’t only affect star visibility．It can harm wildlife too．It’s clear that artificial light call attract animals，making them go off course”（答案A）．There’s increasing evidence．For example， that migrating birds use sunsets and sunrises to help find their way， says Sydney Gauthreaus Jr.， a scientist at Clemson University in South Carolina．“When light occurs at night，” he says， “it has a very disruptive（破壞性的） influence（答案C）．”Sometimes birds fly into lighted towers（答案D），high rises，and cables from radio and televisioll towers．Experts estimate that millions of birds die this way every year.

　　所以，答案B并未提到。

　　5．Which of the following is closest(最接近的) in meaning（意思） to the title"Light Night，Dark Stars"?

　　A. The night sky is light colored and stars are black夜空是淺色的而星星是黑色的．

　　B. Lights appear at night and stars are seen in the dark

　　光顯現(xiàn)在夜晚而在黑暗中人們看見星星．

　　C. Cities lights illunfinate the night sky and make stars invisible

　　城市的燈光照亮了夜空而使得星星已經(jīng)無法看見．

　　D City lights at night illuminate stars in the sky．

　　夜晚的城市的燈光照亮了天空中的星星。

　　分析：本題是唯一的一道主旨題，所以需要縱觀全文。通過我們對(duì)前4題的解答，完全可以判斷出文章的主題就是說：由于不斷擴(kuò)大的城市，越來越多的城市燈光，已經(jīng)成為一種污染，使得天空中的星星黯然失色，所以答案就是C.
