in 2002 ，thousands of fire happened all over the country， of which 50 percent was caused by smokers who left cigarette-ends everywhere。 those who smoke should make sure that the cigarettes are stubbed out before being thrown away。 also， smoking should not be allowed in public places。 30 percent of fire was caused by defective insulation。 workers should know the importance of good insulation for people's lives。 at homes we must pay special attention to electric wires and make sure that they are safe。 20 percent of fire are caused by children playing with matches。 we should warn children of the danger of playing with matches。
no matter what type of the reason it was， there was one thing in common:carelessness。 so if everyone in the country is careful enough， more fire could be avoided。
