Passage 57
(吉林省实验中学2007届高三第四次模拟考试B篇)
Many deaths from home fires are
the result of burns and panic, but most are caused by deadly smoke and gases.
These fatal fires are often caused by such careless acts as throwing away a
lighted match or cigarette, allowing rubbish to pile up, overloading electrical
wires, or misuse of healing and cooking equipment.
Few families go to bed at night
without first checking to make sure that the doors and windows are locked, but
they overlook a very basic fire safety rule. This rule states that people
should sleep with their bedroom doors closed. Nighttime fires are most serious
because the family is asleep and the discovery of fire is usually too late.
A closed bedroom door gives extra
protected by delaying the gases and fire, thus giving the family a few minutes
to escape.
At the first sight of fire in a
home, it is necessary for everyone to get out of the house, especially children
and elderly persons who may need help. Not everyone flees quickly from a
burning home. Children often panic and hide in closets or under beds. Being
prepared or knowing what to do in case fire breaks out can mean the difference
between life and death. All members of the family should know certain basic
steps.
Everyone should know an escape
route and second route from each room in the house. Very young children and old
persons should receive careful thought when mapping out family escape plans.
Both groups will need special help in escaping from home fires. A family should
determine a way in which any members can sound an alarm. It is likely that fire
may block hallways and prevent a person from reaching other bedrooms : Family
members should be taught not to waste time getting dressed or collecting
valuable possessions. Speed is necessary in escaping from fire.
