If you go into the forest with friends who are older than you, stay with them. If you don't,
you may get lost. If you get lost, this is what you should do.
Sit down and stay where you are. Don't try to find your friends-let them find you. You can
help them to find you by staying in one place.
There is another way you can help your friends or other people to find you. Give them a
signal (信号) by shouting three times. Stop. Then shout three times again. Any signal given
three times is a call for help.
Keep up the shouting, always three times together. Then the people who hear you will know
that you are not just making noise for fun. They will let you know that they have heard your signal.
They will give two shouts. When a signal is given twice it is an answer to a call for help.
If you don't think you will be found before nights comes, get some branches (树枝).Try to put
them together so that they make a little house. Cover up the holes with branches that have lots of
leaves. Make yourself a soft bed with leaves and grass.
What should you do if you get hungry or need drinking water? You should leave your little branch
house to look for a river. Don't just walk away. Make a trail (痕迹) for yourself so you find your
way back. Do this by picking off small branches and dropping them as you walk.
