大城市的火灾事故(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 the 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 don't 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 people's 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.
