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(逃脱) 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.

You hurry into the kitchen,open the refrigerator and suddenly you forget why you open it.“What am I looking for?”You ask yourself.“What am I doing here?”Don't worry.You are not losing your mind.We have all had this kind of thing.If you think about something very quickly,it goes into your short-term memory and it goes right back out in just a few seconds.You have not moved things from short-term to long-term memory,so you won't be able to remember it later on.
What can you do to help get back your missing short-term memory?You may go back to where you were.So,for example,if you were sitting in a chair listening to the music in the living room,just go back into the living room.This will help you remember,and when you are back in the living room,you will suddenly think,“Oh,yes,I was thirsty and I wanted something cold to drink.That is why I went to the fridge.”If,sometimes,you can't go back to where you were before,just try tracing your steps back in your mind.Think back to things you did before,and this may help you.
