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.

★ when，while，as引导时间状语从句的区别
when，while，as都可以引导时间状语从句，但用法有区别：
⑴ when可以和延续性动词连用，也可以和短暂性动词连用；而while和as只能和延续性动词连用。
① He was reading in the park when I saw him. （see为短暂性动词）
② Sorry，I was out when you called me．（call为短暂性动词）
③ He comes while we are watching T V.
④ The students took notes as they listened．学生们边听课边做笔记。
⑵ when从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while和as从句的谓语动作必须是和主句谓语动作同时发生。
① When he had finished his homework，he had a short rest．当他完成作业后，他休息了一会儿。
② When I got to the airport，the plane had left． 当我赶到飞机场时，飞机已经离开了。
③ When ／While ／As we were dancing，a stranger came in．当我们跳舞时，一位陌生人走了进来。
2 ④ When ／While ／As she was making a phone call，I was writing a letter．当她打电话时，我在写信。
⑶ 当主句、从句动作同时进行，从句动作的时间概念淡化，而主要表示主句动作发生的背景或条件时，只能用 as。这时，as常表示“随着……”；“一边……，一边……”之意。
① As the time went on，the weather got hotter．（as表示“随着……”之意）
②As years go by，China is getting stronger and richer．随着时间一年一年过去，中国变得越来越富强。
④The little girls sang as they walked in the street．小姑娘们一边走，一边唱。
