Electricity
电
Electricity is one of the most important inventions ever. It is the thing that powers the Earth. If there was no electricity, we'd be back in the dark ages. Few people stop and think just how amazing electricity is. With the flick of a switch, you can power almost anything. Think about what would happen if there was no electricity. We'd have no TV, no computers, no traffic signals. It would be like going back to living in caves. There are a few negative points about electricity, of course. Number one, it's dangerous. Thousands of people die each year from electrocuting themselves or in electrical fires. And number two, it isn't good for the environment. Most electricity comes from burning coal and that creates greenhouse gasses.
电是有史以来最重要的发明之一。它是地球的动力。如果没有电，我们就会回到黑暗时代。很少有人停下来想一想电是多么神奇。只要轻按一下开关，你几乎可以给任何东西供电。想想如果没有电会发生什么。我们将没有电视，没有电脑，没有交通信号灯。这就像回到穴居时期一样。当然，电也有一些不好的地方。第一，它很危险。每年有成千上万的人死于触电或电气火灾。第二，它对环境不好。大部分电力来自燃煤，这会产生温室气体。
