　　參考文章:

　　Ever since early last century, electricity has become an essential part of our modern life.The most obvious example is that electricity lamps give us light at night. Besides, electricity is needed when we watch TV or listen to the radio. Electricity is also essential for many household appliances such as air-conditioners, refrigerators and microwave stoves. In a word, there is hardly anything in our modern life that has nothing to do with electric power

　　If there were no power, our world would be in a state of confusion. For one thing, machines in factories would stop running and we would have to go without many essential industrial products. For another, our life would be seriously affected. For example, all the modern communications were shut up, running water would stop, and all the banks, schools, hospitals and post offices were closed. Without power, the result would be terrible.

　　Therefore, people should realize the importance of electricity and do everything to guarantee a steady supply of power. On the one hand, we should cultivate a sense of saving electric power. On the other hand, more power stations should be built and other energy resources must be found so as to provide sufficient power for the increasing demand
