CELL phones help us easily find people anywhere at any time. A cell phone can include many things, such as games, music and Internet access. Today, 4.6 billion people around the world have cell phones, according to CBS News.
    However, cell phones may cause cancer（癌症）, according to the World Health Organization. In a 2010 study, people who used a cell phone for 10 years or more were more than two times as likely to get cancer, according to CNN.
    The following suggestions may help you reduce your risk of cancer:
    1. Use a headset（头带式耳机）or speaker
    Headsets give out much less radiation（辐射）than phones. Some wireless（无线的）headsets give out low-level radiation. However, you should take it off your ear when you’re not talking to anyone. Using your phone with a speaker will also make it safer.
    2. Listen more, talk less

Your phone gives out radiation when you talk or text, but not when you’re listening or getting messages. Listening more and talking less can lower the risk of cancer.
    3. Hold the phone away from your body

 Hold the phone away from your body when you’re talking, not against your ear. Also, don’t keep it in your pocket.
    4. Choose texting over talking
    Phones emit（发出）less radiation to send texts than to carry a person’s voice. Texting also keeps radiation away from your head.
    5. Poor signal? Stay off the phone
    Fewer signal bars on your phone mean that the phone needs to give out more radiation to work. Make and take calls when your phone has a strong signal.

“When can I get a cell phone?” The answer is when your parents think you need one, though many kids seem to be getting them around age 12 or 13. Some younger kids may have them because their parents see it as a matter of safety and convenience. For example, a kid can call mom and dad when sports practice is over. And a cell phone can give kids almost instant access(快捷通道) to their parents if something goes wrong or they need help. It can give parents quick access to their kids so they can check on them and make sure they’re OK.

If you do get a cell phone, make some rules with your parents, such as how many minutes you’re allowed to spend on the phone, when you can use your phone, when the phone must be turned off, and what you will do if someone calls you too often, and so on.

You’ll also have to learn to take care of the phone in your life. Keep it charged(充电) and store it in the safe place so it doesn’t get lost. And whatever you do, don’t use it in the bathroom. I know someone who dropped her phone in the toilet!

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.
