Introduction We use electricity every day. We use electricity in lamps, computers, and refrigerators. We use electricity to cook, to watch television, and to listen to music. What do you use electricity for? How do we make electricity? Discover! Now read and discover more about electricity!

我们每天都要用电。 我们在灯、电脑和冰箱中使用电。 我们用电做饭、看电视、听音乐。 你用电做什么? 我们是如何发电的? 发现!现在阅读和发现更多关于电的知识!

Chapter 1 Electricity Electricity is a type of energy. Energy makes things work. We use electricity to make machines work. We use electric machines in our homes, schools, and offices. We can use electricity in trains, cars, and some buses, too! Electric machines help us to do many things in the kitchen. We use a kettle to make water hot. We use a refrigerator to keep our food cold, and we use a stove to cook our food. We use a washing machine to wash our clothes, and we use a dishwasher to wash our dishes. How many electric machines can you see here?

电是一种能源。 能量使事物运转。我们用电使机器运转。 我们在家里、学校和办公室使用电机。 我们可以在火车、汽车和一些公共汽车上使用电力!电动机器帮助我们在厨房里做很多事情。 我们用水壶把水烧热。 我们用冰箱冷藏食物，用炉子做饭。 我们用洗衣机洗衣服，用洗碗机洗盘子。 你在这里能看到多少台电动机器?

Chapter 2 Electricity in Nature There's electricity in nature. In the Arctic and the Antarctic, electricity from the sun makes red and green colors in the sky. The colors are amazing! Lightning is a type of electricity in the sky, too. Lightning has lots of energy. It's very, very hot. When you see lightning in the sky, go into your home. Lightning can give you an electric shock. That's when electricity goes into your body. Then it can kill you! Discover! The electric ray has electricity in its body. It uses electricity to catch and eat other fish!

自然界有电。 在北极和南极，来自太阳的电使天空呈现红色和绿色。 颜色太棒了!闪电也是天空中的一种电。 闪电有很大的能量。 非常非常热。当你看到天空中有闪电时，赶紧回家。 闪电会使人触电。 那就是电流进入你身体的时候。 然后它会杀了你!发现!电鳐体内有电。 它用电来捕捉和吃掉其他的鱼!

Chapter 3 How We Make Electricity We make electricity in power stations. We use this electricity to make machines work. Many power stations use coal to make electricity. We burn the coal to make water hot. Hot water makes steam. The steam turns a turbine. The turbine turns a generator. Then the generator makes electricity. Some power stations don't use coal. This power station uses water from a river. The water in the river turns turbines. We can use wind to make electricity, too. This is a wind farm. The wind turns turbines to make electricity.

第三章我们如何发电我们在发电站发电。 我们用这种电使机器运转。 许多发电站用煤发电。 我们烧煤使水变热。 热水产生蒸汽。蒸汽使涡轮机转动。 涡轮机带动发电机运转。 然后发电机发电。 有些发电站不使用煤。 这个发电站用的是河水。 河水使涡轮机转动。 我们也可以利用风来发电。 这是一个风力发电厂。风带动涡轮机发电。
