If you are lost in the mountains, stay calm in the face of darkness, loneliness, and the unknown. It will greatly increase your chances of survival. Many people think that preparing necessary equipment and knowing how to use it are very important, but actually eighty percent of mountain survivals is your reaction(反应) to fear.
Find a hiding place.
Unnecessary efforts 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 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(救援者) 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 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, as search teams will be trying to follow your path and may miss you if you have gone off in a different direction. Searchers often end up finding a car with no one.
If you get frostbite（冻伤）, do not rewarm 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.

If you are one of those who want to know how to increase your vocabulary, there are some ways you may find useful. In fact, it is not that difficult to learn new words, but to remember them for a lifetime seems not to be so easy.
To make it easier, you can try word associations（联想）. Try to find a connection between a new word and things or people you know. For example, if your neighbour is an unselfish person who cares about the needs of other people, think about this person every time you see the word, and very soon you'll start actively using it.
Try to use the words you learn as often as possible. Perhaps you are not sure which situations they should be used in, or whether you pronounce（发音） them correctly, but practice is the best way to understand that. It is not enough to find out the meaning of a word. You should hammer (敲打) it into your mind by using it in actual conversations in everyday life.
Also, it may be helpful to know the meaning of the word roots, prefixes (前缀) and suffixes （后缀）， especially if they have a Greek or Latin origin（起源）． Even if you meet a long unfamiliar word, it will be easy to know its meaning if you know the general meaning of its parts.  For example, if you see the word "philanthropy", it won't be difficult to surmise what it means if you know that "anthropo" means "human" and "philo" means "loving". Not only can ancient Greek and Latin be helpful, but a number of modern languages as well. So, if you speak French,  Italian, Spanish or Portuguese, guess the meaning of an unfamiliar English word if it sounds like  a word from another language you know.
