Question

英语翻译
Glaciers may form in permanently cold areas,and these slowly moving masses of ice cut out valleys,carrying with them huge quantities of eroded rock debris.
1.them 指代什么,为什么.
2.翻译全句.

Answer 1

them 指代masses of ice,因为“huge quantities of eroded rock debris”是伴随着masses of ice移动的.
全句翻译为：
冰川可以永久存在于寒冷地区,而这些缓慢移动的大量冰块却切削着峡谷,它们带走了大量被侵蚀的岩石碎片.
