空氣-Air
Air
Air is all around us. It＇s around us as we walk and play. From the time we were born, air was around us on every side. When we sit down, it is around us. We live in air.
All living things need air. Living things can＇t live without air. We can go without food or water for a few days but we can＇t 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 can not see it.
We can only feel it. We can feel it when it is moving. Moving air is called wind. How can you make air move? Here is one way. Hold an open book in your hands in front of you. Close it quickly. What can you feel? What you feel is the air.
空氣
空氣包圍著我們，當我們走路和玩耍的時候，它在我們周圍。從我們誕生之日起，空氣就在我們周圍了。當我們坐下時，它在我們身邊。我們生活在空氣中。
所有生物都需要空氣，沒有空氣生物就不能生存。沒有水和食物，我們可以生存幾天，但是沒有空氣幾分鐘我們都無法生存。我們吸進空氣。當我們工作或跑步時，需要較多空氣。當我們睡著時，需要的空氣會少一些。
我們生活在空氣中，但我們看不見它。
我們只能感覺到。當空氣運行時，我們可以感覺到它。運動的空氣形成風。你怎樣使空氣運動呢?有一種辦法，手中拿一本展開的書放在面前，快速合上書，你能感覺到什么?你感覺到的就是空氣。
