参考译文
如今大部分人在生活中很难看到天空中的繁星，这真是一件憾事。星光灿烂的夜空只有在图片里才能见到。不仅城市和郊区是这样，连乡村也是如此。我们不但看不到星星，同样这也污染了夜空的环境。如果光污染是人类进步所不可避免要付出的代价，那么这种损失或许可以被接受，但事实并非如此。大多数人工白昼是不必要的，因为它们并非是用来增加夜晚安全或照明的，它们只是发出耀眼的光。仅在美国一年就在此项上花费十亿多美元。光污染给科学带来的影响更加严重。科学家们需要用精密仪器观察极其细微的物体，这种观测需在没有空气污染和城市灯光的环境下才能进行。例如，一些物体的影像可以提供宇宙遥远角落的信息，帮助我们了解地球实际形成的方式。然而，这些物体发出的光线可能在到达地球时被人工光源所覆盖而消失。减少光污染并不难，需要政府官员和公民们意识到这个问题并面对它。就个人而言，仅在必要时使用照明，就能有助于大幅减少人工白昼现象。闪耀在我们上空的星星是无价的文明遗产，我们必须尽我们所能去保护它。
26.C【精析】本题考查介词词义辨析。on“在…之上”;from“来自…”;in“在…里”;at“在(场合)”。根据句意，应是“在图片里”，C选项符合题意，故选C。

29.C【精析】本题考查的是情态动词用法。此句中的if是非真实条件句，是一种虚拟和假设，如果光污染是进步所必须付出的代价，那么这种损失或许可以接受，might符合题意，故选C。
30.A【精析】本题考查的是上下文语义的衔接。此句是虚拟，事实并非如此，所以应用转折，故选A。、
31.D【精析】本题考查形容词辨析。inadequate“不恰当的”;invisible“看不见的”;unpredictable“不可预知的”;unnecessary“不必要的”。由上下文可知，此处应表达的是许多人工照明其实是不必要的，unnecessary符合题意，故选D。
32.A【精析】本题考查名词词义辨析。由上文说人工白昼是不必要的，下文解释原因，“它们并非是用来增加夜晚安全或照明的，它们只是发出耀眼的光”。nighttime“夜晚”;lifetime“一生”;peace—time“和平时期”;longtime“长时间”。由题意可知A选项正确，故选A。
33.A【精析】本题考查动词词义辨析。cost“花费”;make“制作”;put“放置”;raise“提高”。此处是说花费美国十亿美金，故选A。
34.C【精析】本题考查介词词义辨析。at“在(场合)”;from“来自…”;over“超过，在…之上”;for“对…来说”。此处是对于科学来说，for符合题意，故选C。
35.B 【精析】本题考查动词搭配。此处的动词是跟前面的observations搭配的，只有make符合，故选B。
36.D【精析】本题考查固定搭配。四个选项中，只有free可以和后面的of搭配，表示“没有、免除”，故选D。
37.B【精析】本题考查动词词义辨析。collect“收集”;offer“提供”;share“分享”;save“保存”。此处意为一些物体的影像可以为研究提供信息，0ffer符合题意，故选B。
38.D【精析】本题考查定语从句的引导词。此引导词要修饰先行词way，前面又有in搭配，应为in which表示一种方式，故选D。
39.D【精析】本题考查连词用法。根据上下文意思，此处应为转折，besides“而且”;instead“而不是”;therefore“因此”;yet“然而”。故选D。
40.C【精析】本题考查名词词义辨析。march“行进”;visit“参观”;joumey“旅途”;flight“飞行”。此处意为这些物体的光线可能在到达地球的途中被覆盖，只有journey有旅途之意，故选C。
