A company called CLF Aggregates makes a product for roads, and 30% of the material is crushed glass.

一家叫做CLF Aggregates的为道路提供产品的公司用到了30%的细碎玻璃作为材料。

Now something snuffled, then it crackled, and again the thin layer of ice resounded like a mass of crushed glass.

一会儿有什么东西在吸鼻子，一会儿又噼啪作响，薄薄的冰层又一次像一堆碎玻璃一样回响。
