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
想像一下，如果你有一座用積木拼成的大城堡，現在你想把它拆成一顆一顆最初始的零件，以便重新組裝。在英文中，我們會用哪一個動詞組來形容這種「將複雜整體拆解回原始單位」的動作呢？

太棒了！你能精準捕捉到科學文本中的動詞變化，代表你對文意脈絡的掌握非常敏銳。這題的關鍵在於理解該細菌對 PET 塑膠所做的「動作」。
物質分解的精準表達
在科學描述中，當我們提到將一個複雜的聚合物轉換成較小的分子或「基本元素（basic elements）」時，這就是一個分解的過程。選項 (C) break down 正是「分解、瓦解」的意思，完全符合文章中描述 I. sakaiensis 處理塑膠的機制。相較之下，其他選項如 break with（斷絕關係）、break into（闖入）或 break out（爆發）在語義上都無法與後續的科學還原過程銜接。
