Have you ever been to the forest alone or with your friends during your holiday? If you go into the
forest with your friends, stay with them. If you don't, you may get lost. If you really 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 by staying in one
place. There is another way to help your friends or other nearby people to find you. Give them a signal
(信号) by shouting or whistling(吹口哨) three times. Stop. Then shout or whistle three times. Any signal
given threetimes is a call for help.
Keep up the shouting or whistling, always three times together. When people hear you, they will
know that you are not just making noise for fun. Theywill let you know that they have heard your signal.
They will give two shouts, two whistles or two gun shots(枪声). When someone gives such a signal, it is an
answer to a call for help.
If you don't think that you will get help before night comes, try to make a little house with branche
(树枝). Make yourself a soft bed with leaves and grasses. What should you do if you get hungry or need
drinking water? You would have to leave your little branch house to look for a river. Don't just walk away.
Pick off small branches and drop them as you walk so that you can find your way back.
