      If you go into the forest (森林) with friends, stay with them. If you don't, you may get lost (丢失). 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 find you by staying in one place. There is another way to help your friends or other

people to find you. You can shout or whistle (吹口哨) three times. Stop. Then shout or whistle three times

again. Any signal (信号) given three times is a call for help.

      Keep up shouting or whistling. Always three times together. When people hear you, they will give you two

shouts or two whistles. When a signal is given twice, it is an answer to call for help.

      If you don't think that you will get help before night comes, try to make a little house with branches (树枝).

Make yourself a bed with leaves (树叶) and grass.
