能源无处不在!帕特里夏·沃尔什

Introduction You skip and hop. You turn on lights and listen to a radio. You watch TV and eat food cooked on a stove. All of these things use energy. Energy is everywhere.

你又跳又跳。 你打开灯，听收音机。 你看电视，吃炉子上煮的食物。 所有这些都需要消耗能量。 能源无处不在。

What Is Energy? Energy is the ability to do work or to make a change. There are many kinds of energy. For example, energy gives you light, and it carries sound to your ears. Energy gives power to things that move. It keeps you warm and runs your computer. Let's think about the many ways you use energy in your everyday life.

什么是能源?能量是做功或做出改变的能力。 能量有很多种。 例如，能量给你光，它把声音传到你的耳朵。 能量给运动的物体以动力。 它可以让你保持温暖，运行你的电脑。 让我们想想你在日常生活中使用能源的多种方式。

Light Energy When light comes in through your window, your room becomes bright. You may turn on a light in the bathroom. These things use light energy. Light makes dark places bright. It can come from the Sun or from a lamp. Wowser! The light from the Sun has to travel for about 8 minutes before it reaches us on Earth.

当光线从你的窗户射进来时，你的房间变得明亮起来。 你可以打开浴室的灯。 这些东西使用光能。 光使黑暗的地方明亮。 它可以来自太阳或灯。 老古板!来自太阳的光要经过大约8分钟才能到达地球。

Light travels in a straight path. It travels through air, and it can go through clear glass. It reflects off mirrors. But it stops when it hits your hand. That's why you can make shadows with your hands.

光沿直线传播。 它可以在空气中传播，也可以穿过透明的玻璃。 它被镜子反射。但当它碰到你的手时就停止了。 这就是为什么你可以用手制造阴影。

Sound Energy When you leave for school, you might hear the noise of cars and trucks. You may hear birds singing, music playing, or a friendly voice saying, "Good morning." All of these things are kinds of sound energy. Sounds happen when air vibrates, or moves back and forth.

当你去上学的时候，你可能会听到汽车和卡车的噪音。 你可能会听到鸟儿在唱歌，音乐在演奏，或者一个友好的声音在说:“早上好。” 所有这些都是声音能量的一种。 当空气振动或来回移动时，声音就会产生。
