Confronted with the energy crisis, we should take a series of effective measures to save energy. For one thing, it is high time that people all over the world realized the severe fact that our natural resources have been fixed since the earth was created. For another, the governments of all countries are supposed to lay down the rules and regulations to restrict the amount of gas used by cars. Finally, scientific researches should be encouraged to work out efficient methods of saving fuels and to seek new sources of energy.

　　Personally, I believe that solar energy is a possible source of clean, inexpensive and abundant energy. It does not pollute the environment and costs only as much as the installation of solar panels to absorb the suns rays. Consequently, Im confident that a bright future is awaiting us because solar energy will be able to help us to solve the energy crisis.

　　10. Fire Accidents in Big Cities

　　In recent years there has been a marked growth of fire accidents in big cities of our country. Almost every day we see fire engines rushing through streets. Fires have not only resulted in heavy economic losses but also injured and killed many people.

　　What are the causes of fire accidents? Most of the fires are brought about by carelessness and violation of fire safety regulations. Others are due to the poor quality of home electrical appliances. By the way, some people dont know how to use them properly. Besides, there are quite a few businesses which focus so much of their attention on profits that they tend to neglect and even ignore fire precautions.

　　In my opinion, in order to prevent fires we should first of all foster peoples sense of fire prevention. The second thing we have to do is to increase the number of professional fire fighters, to whom regular training courses should be offered. Finally, we are to improve the existing fire engines and add more fire facilities to high-rise buildings. In this way, a reliable fire prevention system will be formed.
