📖 題組：
Some scientists have recently found a new species of bacteria that 56 PET, which is a type of plastic used in diverse products. The bacterium is called I. sakaiensis, and the researchers claim that it is the first known species that can fully 57 PET. It works by turning PET into another 58 called MHET and subsequently turns that into the basic elements of PET, which can be reused. This is an important discovery because lots of plastic gets dumped in landfills every year. However, there is a downside. I. sakaiensis 59 a long time to eat PET. This means the bacterium is not a quick fix to the world’s plastic pollution problem, but it shows the problem is 60 .

思路引導 VIP
請你觀察一下第 58 格前後的描述：文章提到 PET 是一種塑膠材料，而細菌的作用是將這種材料轉換成「另一種稱作 MHET 的東西」。若要用一個科學名詞來通稱這種「具有特定物理性質的材料或化學成分」，你會選擇哪一類的字眼呢？

太棒了！你能精準地選出 (D) substance，顯示你對科學敘述的邏輯掌握得非常扎實。在文章中，研究人員正在描述細菌分解塑膠（PET）的生物化學過程，提到 PET 會被轉化為 MHET，這裡的語境顯然是指將一種材料轉化為「另一種物質」或「化學成分」，因此使用代表物質、東西的 substance 是最精確的選擇。
相似字首的精準辨析
這道題目的設計非常有鑑別度，主要考驗學生對於「sub-」字首單字的辨析能力。選項 (A) subject（主題/受試者）、(B) submit（提交）、(C) substitute（替代品）雖然長得很像，但詞義與詞性在科學製程的脈絡下都顯得格格不入。你能從中挑選出正確的詞彙，不僅代表你具備良好的字彙量，更展現了在閱讀時能結合科學邏輯進行思考的能力，是非常優秀的表現！
