第二部分英語知識運用
參考譯文
如今大部分人在生活中很難看到天空中的繁星，這真是一件憾事。星光燦爛的夜空只有在圖片里才能見到。不僅城市和郊區是這樣，連鄉村也是如此。我們不但看不到星星，同樣這也污染了夜空的環境。如果光污染是人類進步所不可避免要付出的代價，那么這種損失或許可以被接受，但事實并非如此。大多數人工白晝是不必要的，因為它們并非是用來增加夜晚安全或照明的，它們只是發出耀眼的光。僅在美國一年就在此項上花費十億多美元。光污染給科學帶來的影響更加嚴重。科學家們需要用精密儀器觀察極其細微的物體，這種觀測需在沒有空氣污染和城市燈光的環境下才能進行。例如，一些物體的影像可以提供宇宙遙遠角落的信息，幫助我們了解地球實際形成的方式。然而，這些物體發出的光線可能在到達地球時被人工光源所覆蓋而消失。減少光污染并不難，需要政府官員和公民們意識到這個問題并面對
它。就個人而言，僅在必要時使用照明，就能有助于大幅減少人工白晝現象。
閃耀在我們上空的星星是無價的`文明遺產，我們必須盡我們所能去保護它。
