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.

How green are you? Do you know how to be green?
We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.
Reduce
Reduce means “use less”. Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse
Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup of a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
Recycle
Recycle means “change things into something else”. Though it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
So please remember these three words: reduce, reuse and recycle.
