CGTN原文：

A group of Chinese material scientists have created a biodegradable and recyclable form of glass with a minimal environmental footprint, which may contribute to the sustainable economy if commercialized in the future. The researchers from the Institute of Process Engineering under the Chinese Academy of Sciences fabricated a family of eco-friendly glasses of biological origin, using biologically-derived amino acids or peptides through heating-quenching, a classic industrial procedure.

一群中国材料科学家发明了一种可生物降解、可回收的玻璃，这种玻璃对环境的影响最小，如果将来商业化，可能会对可持续经济做出贡献。中国科学院过程工程研究所的研究人员通过加热-淬火这一经典的工艺，使用生物来源的氨基酸或多肽，制造了一系列生态友好型生物起源玻璃。

1.a biodegradable and recyclable form of glass 一种可生物降解、可回收的玻璃（biodegradable adj.可生物降解的 recyclable adj.可回收的）

2.environmental footprint 环境影响（footprint n.足迹）

3.contribute to the sustainable economy 对可持续经济做出贡献

4.be commercialized 商业化

5.Chinese Academy of Sciences 中国科学院

6.eco-friendly adj.环境友好的

【拓展】

7.cause long-term environmental hazards 造成长期的环境危害

例句：Glass is essential to human life, but the widespread use of non-biodegradable glass that cannot be naturally eliminated causes long-term environmental hazards.

玻璃对人类生活至关重要，但无法自然消除的不可生物降解玻璃的广泛使用，会造成长期的环境危害。
