Unnecessary labor will make you sweat and make you cold.Find a hiding place around you before trying to start your own construction.If you are in a snow-covered area，you may be able to dig a cave in deep snow for protection from the wind.You should try to hide yourself in the middle of the mountain if possible.Stay out of the valleys—cold air falls，and the valley floor can be the coldest area on the mountain.

　　SIGNAL RESCUERS FOR HELP

　　The best time to signal rescuers is during the day.Signal for help from the highest point possible—it will be easier for rescuers to see you，and any sound you make will travel farther.If you take a box of matches and a space blanket(a special blanket for traveling)，build three smoky fires and put your blanket—gold side facing out—on the ground.

　　DO NOT WALK AWAY

　　It will make finding you more difficult if you have gone off in a different direction，as search teams will be trying to follow your path.Searchers often end up finding a car with no one in it.

　　If you get frostbite，do not re-warm the affected area until you’re out of danger.You can walk on frostbitten feet，but once you warm the area and can feel the pain，you will not want to walk anywhere.Try to protect the frostbitten area and keep it dry until you are rescued.

　　Title What should you do when 1.______ in the mountains？

　　Theme Don’t get frightened in 2.______.
