The worst danger is a house on fire when people are asleep. Always be ready to leave through a window into the garden by making sure you can open it if necessary. If you should be on holiday in a tall building or hotel,     1     you know where the fire escape is. When you can’t find any way out, try to     2     a window and shout for help. If you find a big fire burning in your home, get out right away. When you get out in the smoke, try to crawl on your hands and knees because smoke rises and the air will be     3     near the floor. Smoke is a killer and more people have died from breathing it in than actually being burnt.

In recent years, there has been a marked growth of fire accidents in big cities. What are the causes of fire accidents? Most of the fires are brought about by carelessness and violation (违反) of fire safety regulations. Others are due to the poor     6     of home electric 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 (防范).

In order to prevent fires, we should first of all     7     people’s awareness of fire prevention. The second thing we should do is to train professional fire fighters. Finally, we should     8     the existing fire engines and add more fire facilities to high-rise buildings. In this way, a reliable fire prevention system will be formed.
