We all know the dangers of fires. It’s good and necessary for a family to learn how to prepare for a fire. Here are some suggestions.
Put a smoke alarm(火警) in the house. Smoke from a fire causes the alarm to go off. The alarm makes a loud sound. The sound tells everyone to leave the house at once.
Make escape plans. We should know all the ways out of the house. If there is a fire, everyone follows the plan to get out. Part of the plan is to check all the windows to make sure they can be opened easily.
Buy fire extinguishers(灭火器) in the house. Everyone in the family should know how to use them.
Practise for a fire. We do fire practice because we teach children about fire safety. Everyone in the family should know the following fire rules:
★Don’t open a hot door! The fire can grow more quickly if you open the door.
★Stay close to the floor! Smoke can be more dangerous than fire. The best air is near the floor because smoke rises.
★What will you do if your hair or clothes start to burn? First, stop! Don’t run! The fire burns faster because of more air. Drop! Fall to the floor. Then roll! Turning over and over will make the fire go out. Put a blanket(毯子) around you to keep air away from the fire that may still be on you.
There are many possible causes for fires. A wise family is ready all the time. If there is a fire, don’t forget to call 119 for help.

Besides calling 911, here is what to do in some life-threatening emergencies when no oneis
|
Lost in the wilderness
First, you’ve got to acknowledge you’re in trouble. Stay where
you can be seen clearly and remember to rest. Keeping a sense
of humor helps too—it reduces stress and helps creative thinking.
In a wide open area, make a colorful cross out of rocks to show
your present position.
|
Aim to hit the top of the chair against your stomach, in the soft part
below the bony upside-down V of the ribs(肋骨). Make a sudden
push against the chair. If you still can’t breathe after six tries, call 911,
even if you can’t talk. Write the word choking somewhere nearby, and
leave the line open until help arrives.
|
Use your hand or clean cotton, or paper towels, or a scarf,
or any cloth you can find, and push down on the wound
until the bleeding stops. But if you put a band around
your leg tightly, you’re going to close the vessels(血管)
to the entire leg. In this way, you could lose your foot.
Bear attack
|
Instead, stand up and back away slowly, without looking the
bear in the eyes. If it does charge at you, stick out your chest,
raise your arms, and spread your legs. Shout at the bear, to
frighten it. If it’s going to attack, lie facedown, with your hands
held firmly behind your neck. Play dead until you’re sure the bear
is gone.
