[1]Freezing weather can mean frostbite(冻伤)and hypothermia(体温过低)unless a person is prepared. Today we talk about how to stay warm，dry and safe．
[2]Frostbite is damage that happens when skin is exposed to extreme cold for too long．It mainly happens on the hands，feet，nose and ears．If deeper tissue is affected, a person is likely to feel pain every time the area gets cold．Hypothermia is a condition that develops when the body cannot produce as much heat as it：releases．Signs of hypothermia include uncontrollable shaking，very slow breathing and difficulty thinking clearly．
[3] To avoid cold-related injuries，here is a simple way to remember four basic steps to staying warm．Think of COLD—C．O．L．D．
[4]The C stands for cover．Wear a hat and scarf to keep heat from escaping through the head，neck and ears．And wear mittens(连指手套)instead of gloves．
[5]The O stands for overexertion(用力过度)．Avoid activities that will make you sweaty．Wet clothes and cold weather are a dangerous combination．
[6] L is for layers．Wearing loose，lightweight clothes，one layer on top of another，is better than wearing a single heavy layer of clothing.
[7]D is for dry．In other words，stay as dry as possible．Pay attention to the places where snow can enter clothing．These include the tops of boots，the necks of coats and the wrist areas of mittens or gloves．
[8] And here are two other things to keep in mind-one for children and    ．Eating snow might be fun but it lowers the body’s temperature．And drinking alcohol might make a person feel warm．But what it really does is weaken the body’s ability to hold heat．
