She has free air under her diaphragm.

她横隔膜下有游离气体。

This also keeps the air, soil, water and crops free from chemicals.

同时还可以让空气、土壤、水以及农作物不受 化学物质的污染。

Then out in the free fresh air they swing, Under the sunny sky.

然后他们在自由的新鲜空气中荡秋千， 在晴朗的天空下。

" He may not heed your words, but he will hear them" . Val kissed him lightly on the cheek. " You have my thanks, Lord Snow. For the half-blind horse, the salt cod, the free air. For hope" .

" 他可能不上心，但至少会听听。" 瓦迩轻轻吻了他的脸颊。" 我感谢你，雪诺大人。为了半盲的马，为了腌鳕鱼，为了自由的空气。为了希望。"

That was not long. I declined joining their breakfast, and, at the first gleam of dawn, took an opportunity of escaping into the free air, now clear, and still, and cold as impalpable ice.

我没有待多久。我谢绝与他们进早餐。等到曙光初放，我就抓紧机会，逃到外面的自由的空气里，它现在已是清爽、宁静而又寒冷得像块无形的冰一样了。
