Energy Is Everywhere! Written by Patricia Walsh
能源无处不在!帕特里夏·沃尔什
Energy is everywhere! You use energy to run. Energy turns on the lights. Energy moves sound to your ears. Energy cooks the food you eat.
能量无处不在!你跑步需要消耗能量。 能量把灯打开。 能量把声音传到你的耳朵。 能量能煮熟你吃的食物。
Energy makes work possible. Energy can also change things. There are many kinds of energy.
能量使工作成为可能。 能量也能改变事物。 能量有很多种。
Light is a kind of energy.
光是一种能量。
Open the curtains or turn on a lamp. Light fills your room. It's light energy. Light energy makes dark places bright.
打开窗帘或打开灯。 光线充满你的房间。它是光能。 光能使黑暗的地方明亮起来。
Light moves in a straight path. It goes through air. It can go through clear glass. It reflects off mirrors. But light stops when it hits your hand.
光沿直线运动。 它通过空气。它可以穿过透明的玻璃。 它被镜子反射。但当光线照射到你的手时就会停止。
