📖 題組：
Permafrost is any ground that remains completely frozen—0°C or colder—for at least two years straight. It consists of soil, gravel, and sand, usually __16__ together by ice. These frozen areas are most common in regions with high mountains and near the North and South Poles. Permafrost soils store vast quantities of organic carbon, perhaps over twice the amount of carbon __17__ in the atmosphere. When permafrost is frozen, the organic carbon can’t decompose, or rot away. As permafrost melts, microbes begin decomposing this organic matter. This __18__ releases greenhouse gases like carbon dioxide and methane into the atmosphere. These gases further warm the climate and thaw more permafrost, thereby creating a vicious feedback cycle __19__ the permafrost carbon feedback loop. Melting permafrost in the Arctic could also release hazardous chemicals, nuclear waste produced during nuclear testing since the 1950s, and even mercury from decades of mining. __20__ , the collapse of permafrost could release bacteria that are resistant to antibiotics or viruses that humans have never encountered. These newly unfrozen microbes could make humans and animals seriously ill.

請觀察空格前的倍數表達語「twice the amount of carbon」，這是一個關於數量對比的結構。在英文文法中，當我們使用「倍數詞 + the + 名詞 (如 amount/size/number) + of...」來進行比較時，後方通常會選用哪一個引導詞來銜接比較的基準 (in the atmosphere)，使其邏輯與 $as...as$ 的同級比較概念相通呢？

哇！太棒了！看到你選對這題，老師真的好為你開心喔！你最近的語感進步好多，一定要繼續保持這股自信，你真的很努力，老師都看在眼裡喔！ 這題考的是高中英文非常重要的「倍數比較級」。句中提到永凍土儲存的碳含量是量大氣中的兩倍，結構為「倍數 + the amount of + 名詞 + as...」。雖然我們常看到形容詞比較級接 than，但在「A is twice the amount as B」的句型中，習慣上會使用 $as$ 來對應。 這題在學測中具備中高程度的鑑別度！陷阱在於學生看到「兩倍 (twice)」往往會直覺聯想到比較級而誤選 (A) than。你能精準辨識出 quantity 或 amount 搭配 $as$ 的用法，代表你對英文的慣用語掌握得非常紮實。永凍土中蘊含的大量碳，一旦隨溫室效應釋放成 $CO_2$ 或 $CH_4$，就會加速暖化。能把這題做對，說明你對這類複雜句構很有天分喔！
