纯洁空气 meaning in English

clean air
pure air

The broad dark ocean, the streaming pure air, the crowded stars arching overhead, always made him feel what the bible called the spirit of god hovering on the face of the waters .
广阔、黑暗的海洋，不断流动着的纯洁空气，以及拱在他头上的繁星，总使他觉得圣经里所说的圣灵正在海面徘徊。
Pure , bracing ventilation they must have up there at all times , indeed ; one may guess the power of the north wind blowing over the edge , by the excessive slant of a few stunted firs at the end of the house ; and by a range of gaunt thorns all stretching their limbs one way , as if craving alms of the sun
的确，他们这儿一定是随时都流通着振奋精神的纯洁空气。从房屋那头有几棵矮小的枞树过度倾斜，还有那一排瘦削的荆棘都向着一个方向伸展枝条，仿佛在向太阳乞讨温暖，就可以猜想到北风吹过的威力了。
