导语：我们每天都在呼吸空气，你知道空气是什么吗?下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!
Air is all around us. It is around us as we walk and play. From the time we were born air is around us on every side. When we sit down, it is around us. When we go to bed, air is also around us. We live in air. We can live without food or water for a few days, but we cannot live for more than a few minutes without air. We take in air. When we are working or running we need more air. When we are asleep, we need less air. We live in air, but we cannot see it. We can only feel it when it is moving. Moving air is called wind. How can we make air move? Here is one way. Hold an open book in front of your face, close it quickly. What can you feel? What you feel is air.
空气
我们周围到处都是空气。当我们走路和玩耍时，它就在我们身边。从我们出生的那一刻起，空气就在我们身边。当我们坐下时，它就在我们身边。当我们上床睡觉时，空气也在我们周围。我们生活在空气中。没有食物和水我们可以活几天，但是没有空气我们不能活上几分钟。我们接受空气。当我们工作或跑步时，我们需要更多的空气。当我们睡着的时候，我们需要更少的空气。我们生活在空气中，但我们看不见它。只有在移动时我们才能感受到它。移动的空气叫风。我们怎样使空气运动?这里有一条路。把一本打开的书放在你面前，快把它合上。你能感觉到什么?你所感受到的是空气。
