They are attracted by the American writer’s 21 of the millennia-old glaciers.
答案：(B) descriptions
語意「被這位美國作家對千年冰川的『描述』所吸引」，descriptions（描述）符合，呼應海明威的文學作品描寫；situations（情況）、translations（翻譯）、calculations（計算）都不合。
看到 the American writer's ______ of...，你可能沒細看結構就直接掃選項，挑一個「跟作家有關」的。translations 也跟文字工作有關，於是在它和正解之間猶豫。
先把結構看懂：X's 加名詞再加 of Y，是名詞化的說法，所有格 the American writer's 是動作的發出者，of the millennia-old glaciers 是動作的對象。還原成句子就是 The American writer described the millennia-old glaciers.（這位美國作家描寫了那片千年冰河）。碰到這種名詞化的結構，一律還原成「誰對什麼做了什麼」，語意馬上浮出來。線索其實在上一句就給了：tourists visit Mount Kilimanjaro... to witness the scenes depicted in Earnest Hemingway's The Snows of Kilimanjaro（遊客前來親眼看看海明威「吉力馬札羅的雪」裡所描繪的景象）。depict 就是「描繪」，descriptions 正是它換個說法。空格解不出來時，先回頭找上一句有沒有同義字被換過說法，這是克漏字最常見的線索安排方式。
situations（情況）：作家的「情況」與冰河搭不上，X's situation of Y 這種說法也不成立。translations（翻譯）：海明威用英文創作，而且人翻譯的是文字，不是冰河。calculations（計算）：小說家不做冰河的數據計算，這是科學報告才有的動作。
be attracted by（被…吸引）、give a description of（描述…）、beyond description（無法形容）、centuries-old（有數百年歷史的）、depict somebody as（把某人描繪成…）、witness a change（見證一項改變）。
Every year tens of thousands of tourists visit Mount Kilimanjaro, the highest mountain in Tanzania, Africa, to witness the scenes depicted in Earnest Hemingway's The Snows of Kilimanjaro. They are attracted by the American writer's 21 of the millennia-old glaciers.
However, this tourist attraction will soon 22 . According to the Climate Change Group, formed by environmentalists worldwide to document the effects of global warming, Mount Kilimanjaro's snows and glaciers are melting and are 23 to disappear by 2020.
Not only will the summit lose its tourist attraction, but the disappearance of the snows will also cause major damage to the ecosystem on the dry African plains at its base. 24 the snow covering the peak, there will not be enough moisture and water to nourish the plants and animals below. Rising temperatures, an effect of global warming, 25 threaten the ecosystem of this mountain area. The loss of snows on the 5,892m peak, which have been there for about 11,700 years, could have disastrous effects on Tanzania.
