第26题选

A．on
B．from
C．in
D．at

参考答案C

解析: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。
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。
