  What Would Happen If There Were No Power

  Ever since early this century, electricity has become an essential part of our modern life. It plays an important role in many fields such as industry, agriculture and the daily life of men. Electricity is a source of energy that makes it possible for the factories to turn out products and for people to create comfortable living conditions, for example.

  If there were no electric power, things would be quite different. Machines could not run and people would have to fall back on their hands to produce what is essential for them to keep alive. Traffic would have to stop at night because there would be no lights in the street. A world in darkness would no longer be a pleasant one. In a word, things would be in a mess.

  Therefore, we should realize the importance of electricity. As electricity is insufficient in our country, we should be frugal in using electricity. We should make great efforts to produce more electricity.
