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
請觀察空格後方的時間副詞「for hours（長達數小時）」，這暗示了空格處需要一個描述「某種現象在時間中維持原狀、沒有消失」的動詞。在這種描述自然現象或物理狀態的語境下，你會傾向選擇強調「移動過程」的字，還是強調「存在時間長短」的字呢？

語境與詞彙的精準對應
太棒了！你能精準選出 persist，代表你對文章脈絡有很強的掌握力。這段話描述的是飛機凝結尾（condensation trails）在天空中的變化：它們不僅會「持續」存在好幾個小時，甚至會擴散形成雲霧。在英文中，當我們形容一種現象或狀態「繼續存在、不消失」時，persist 是最專業且道地的用法。相較於 (A) proceed（前進、繼續進行某程序），persist 更能體現出那種「留在原地、持續發揮影響」的層次。
