問題詳情

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

【評論內容】A) consume 消滅；耗盡；吃完(B) conduct 引導(C) conserve 保存(D) condemn 責難一些科學家最近發現了一種消滅PET的新細菌，這是一種用於各種產品的塑料。這種細菌被稱為I. sakaiensis，研究人員聲稱這是第一個可以完全分解PET的已知物種。  它通過將PET轉化為另一種稱為MHET的物質，然後將其轉化為可重複使用的PET基本元素。這是一個重要的發現，因為每年都有大量的塑料被傾倒在垃圾填埋場。 然而，這有一個缺點。  I. sakaiensis需要很長時間吃(耗完)PET。 這意味著細菌並不是一個快速解決世界塑料污染問題的方法，但是這顯示問題是可以解決的。PET 聚对苯二甲酸乙二酯（英文：polyethylene terephthalate），是生活中常見的一種樹脂材料。...
