Read the apssage and answer the questions :-

Sir Ranulph Fiennes, the man the Guinness Book of World Records has named "The World's Greatest Living Explorer," is certainly no stranger to cold. In 1982, he was one of the first people ever to go around the world from pole to pole. In 1980 and again in 1993, he crossed the entire Antarctic
alone! In 2000 he was attempting to walk to the North Pole, a 520-mile journey, on his own, in a record-breaking 80 days. He was doing it both for the challenge and to raise money for cancer research. He had supplies, clothes, maps, and sleds; but there was one thing he hadn't counted on. As
he pulled his two heavy sleds behind him, one of them unexpectedly broke through some thin ice. It quickly began to sink. Knowing that he couldn't last out in this frozen wilderness without it, Fiennes reached into the water with his left hand and pulled the sled back out.
Within a minute Fiennes' hand was frozen and completely useless. He knew that he only had a matter of minutes before his core temperature (the temperature of his major organs) would begin to fall. Disappointed, Fiennes knew he had only one real choice. He had to turn around and go back. This
was no small chore either. The return trip to base camp was 12 hours long. By the time he got there, his temperature was dangerously low, and he was in trouble. He radioed for help and was flown to Ottawa for medical attention. In his own words, "It was a very, very close run thing."

The two main dangers of winter are frostbite and hypothermia. When you are outside in winter weather, they are the ones to watch out for. They can attack while you are sledding, skiing, skating or just shoveling out the driveway.

Hypothermia is known as the "Killer of the Unprepared." If you are out in the cold for too long, and you aren't properly protected, your core body temperature will begin to go down. If your clothes or shoes are wet, this is especially dangerous. Wet clothes can make you lose heat 200 times faster
than if your clothes are dry. If conditions are right, hypothermia can happen even when the temperature is above freezing. The first sign to watch out for is shivering. Your blood begins to cool, and this means you will begin to lose control of your arms and legs. Your brain won't get the oxygen it needs. You will become clumsy and unable to think  straight. You will feel tired, and if your temperature goes low enough, you can faint. If you begin to shiver, get into a warm area to start bringing your body temperature back to normal. Change into dry clothing if your clothes
are damp or wet.

Frostbite is something quite different. It is not usually caused by how long you have been out in the cold, but by how much of your skin is exposed. Ice crystals can form on your skin and in the tissues underneath without you even knowing it. Your hands, feet, nose, ears, and cheeks are the most likely to get frostbitten. The blood vessels in these parts can get smaller, cutting off the supply of blood you need to keep warm. You may feel a tingling feeling in them, or even some pain. Another person may notice a very white or gray spot on your skin if you've been frostbitten. Your skin will feel soft and cold. Frostbite needs immediate attention. Don't wait! Get to a warm place and put on warm, dry clothing. Drink warm liquids. Check your skin. Get medical help if it is hard, blue, blotchy, or blistered.

The best way to protect yourself from a case of hypothermia or frostbite is by doing some simple things. Here are the basics for staying safe in winter weather:
 Dress in layers. Wear loose-fitting, lightweight clothes in three or four layers. You can take a layer or two off if you begin to overheat outside. Wool is the best fabric. It is dryer and warmer than others.
 Always wear a hat or cap. Between 20 and 50 percent of your body heat is lost through your head.
 Wear sunglasses and sun block to protect your eyes and skin. They aren't just for summertime.
 Wear lip balm to protect yourself from chapped lips.
 Wear mittens rather than gloves. They are warmer.
 Know the signs of frostbite and hypothermia and watch for them. Respond right away if you suspect either one.
 Watch the weather report carefully. Check out the wind chill factor (see chart), and talk to your parents about how safe it is to be outside.
 Learn first aid or take a first aid class in how to respond to frostbite and hypothermia.

Winter is a wonderful season. Nothing beats spending a couple of hours sledding with friends and then building a snowman before heading in for a cup of hot chocolate. Just make sure that you are staying safe while you are out there having fun!

Sometimes the weather report can be confusing. Many of the terms sound similar. Here are some common terms and their definitions: Winter Storm Watch: A storm is likely. Winter Storm Warning: The storm is entering the area or is already here.
Blizzard Warning: A combination of snow and wind will create limited visibility, drifting snow, and dangerous wind chills. Winter Weather Advisory: Conditions from recent winter weather can be hazardous (especially for drivers). Frost/Freeze Warning: The temperature will dip below freezing. Ice Storm Warning: There will be dangerous accumulations of ice.Heavy Snow Warning: There will be more than 4 inches in 12 hours or 6 inches in 24 hours.
