三年级英语阅读:小学三年级英语阅读阅读理解 Air空气

Air

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.

空气就在我们身边，我们散步玩耍它都环绕着我们。从我们出生开始空气就在我们周围的每个角落，当我们坐下，它在我们身边，当我们睡觉，空气也在我们身边。我们生活在空气中。我们生活中可以几天没有水和食物，但离开空气超过几分钟我们就没法生存。我们呼吸空气，当我们工作或跑步的时候需要更多空气，当我们睡觉时，需要的空气会少一些。我们生活在空气中，但我们不能看到它。只有在活动的时候才能感受到它，流动的空气称为风。我们怎样才能使空气流动呢？这里有一种方法。在你的面前放置一本打开的书，迅速将其关闭。什么感觉？你感受到的就是空气。
