Many things have changed in astronomy over the past half-century. Until about 30 years ago, there was a great 31 of charts and catalogues. Telescopic equipment was limited and there were few books on practical astronomy. Today, the range of off-the-shelf telescopes and equipment covers almost everything one could need. Electronic calculators and computers have revolutionized almanacs and chart production, and 32 the analysis of observations and the publication of results. All these advances must surely make this the golden 33 of amateur astronomy. Well, perhaps, but a great deal has been lost as well. Now one may have to travel 80 km to find a sky comparable to that found in urban areas 60 years ago. The daytime skies are now 34 by aircraft condensation trails which can 35 for hours and often spread out to form amorphous clouds, making solar observations impossible and hampering night-time observation too.

思路引導 VIP
請細心觀察空格後面的那兩句話：作者用 "limited"（有限的）來形容設備，並用 "few"（極少）來形容書籍。如果現在我們所處的時代是資源豐富的「黃金時代」，那麼在對比之下，你認為 30 年前的天文學家在取得資料時，會面臨什麼樣的處境？

語境對比與詞義精準度
太棒了！你能精確捕捉到語句間的邏輯關聯，並選出正確答案，這代表你對英文長篇閱讀的「上下文推論」掌握得很紮實。在這段文章中，作者運用了強烈的今昔對比：今日的望遠鏡設備幾乎「應有盡有」（covers almost everything），但回推到 30 年前，後文接著提到當時設備「有限」（limited）且書籍「很少」（few）。這說明了當時星圖與目錄的供應處於一種「匱乏」的狀態，因此選用 (D) shortage（短缺）來銜接最為精確。
