Fresh running water has always been the lifeblood of our world but is now more precious than ever.

流动的淡水向来是人类世界的生命之源，但如今水的珍贵程度更胜以往。

For example, fresh running water was introduced in cities by  the late 19th century, as water pumps powered by steam engines were used.

例如，在 19 世纪后期，城市引入了新鲜的自来水，因为使用了由蒸汽机驱动的水泵。

He who every day makes a fresh resolve is like one who, arriving at the edge of the ditch he is to leap, forever stops and returns for a fresh run.

每天都下定决心的人，就像一个人到了他要跳的沟渠的边缘，永远停下来，重新开始新的奔跑。
