If you go into the forest with friends, stay with them .If you don’t, you may get lost. If you do 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 stay in one place.

There is another way to help your friends or other people to find you. Give them a signal(信号)outing or whistling (吹口哨) three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help.

Keep on shouting or whistling, always three times together. When people hear you, they will give two shouts or two whistles. When a signal is given twice, 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 small room with branches.（树枝）
