     Freezing weather can mean frostbite(凍瘡)and hypothermia (低體溫)unless a person is prepared.
Today we talk about how to stay warm,  dry and safe.
     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.
     People with minor cases of frostbite that affect only the skin may not suffer and permanent damage.
But if deeper tissue is affected, a person is likely to feel pain every time the area gets cold.
     Hypothermia happens when the body cannot produce as much heat as it releases. The condition
comes on slowly. Signs of hypothermia include uncontrollable shaking, very slow breathing and difficulty
thinking clearly. If not treated, hypothermia can be deadly.
     To avoid coldrelated injuries, here is a simple way to remember four basic steps to stay warm, Think
of COLD-C.O.L.D.
     The C stands for cover.Wear a hat and a scarf to keep heat from escaping through the head, neck
and ears.And wear mittens(連指手套)instead of gloves.In gloves, the fingers are separated, so the
hands may not stay as warm.
     The O stands for overexertion. Avoid activities that will make you sweaty. Wet clothes and cold
weather are a bad mix.
     The L stands for layers. Wearing loose, lightweight clothes, one layer on top of another, is better
than wearing a single heavy layer of clothing. Also, make sure outerwear is made of material that is
water resistant and tightly knit.
     The D stands for dry.In other words, stay as dry as possible. Pay attention to the places where
snow can enter, like the tops of boots, the necks of coats and the wrist areas of mittens.
     Hypothermia can be mild, moderate or severe. Mild hypothermia is something that most people
have experienced if they live in cold climates. You feel so cold that your body starts to shake-not very
much, but uncontrollably.
     The treatment for mild hypothermia starts with getting out of the cold and, if necessary, changing into
dry clothes.Drinking warm, nonalcoholic liquids and eating something sugary can stop the shivering.
     Taking a warm bath or sitting by a fire or doing some exercise can also help the body warm up.
These are all common sense treatments.
     But the treatment needs change when people enter the moderate or severe stages of hypothermia.
In that situation,  their body temperature drops below thirtyfive degrees Celsius. They lose the ability to
think clearly. Their muscles become stiff.They might bump into things or fall over objects.
     It is important to work fast to get people out of the cold.Hypothermia victims need medical help as
soon as possible. But it is equally important to move them slowly and gently.

Marley is a businessman. His business is freezing people. He works for a company in California called Trans Time. Trans Time freezes people after they die. Why does Trans Time freeze people? Doctors today can cure many diseases, but they cannot cure all diseases. People still get sick and die. Maybe in the future doctors will have medicine for all diseases. Some people think so. They want Trans Time to freeze their bodies after they die. Maybe 100 or 200, or 300 years later, Trans Time doctors will bring the people back to life. The doctors will cure their diseases, and the people will be alive and healthy again.

People often ask the scientists at the Trans Time, “How will Trans Time bring dead people back to life?” They say, “We can freeze a healthy animal and bring it back to life. We think that someday it will be possible with human.” When they say “someday”, they mean years from now — maybe 100 or 200 years. How can Trans Time keep people frozen for 200 years?

After a person dies, workers at Trans Time cool the body with ice and chemicals. When the body is very cold, workers put the body into a capsule (密封艙). They fill the capsule with liquid nitrogen (液氮). The temperature in it is 196 degrees centigrade below zero. Every two weeks workers add more liquid nitrogen. The liquid nitrogen keeps the bodies frozen.

Trans Time charges $21,000 to freeze a body and $59,000 to keep a body frozen. That’s $80,000 all together. It is a lot of money. But some people think that $80,000 is a fair price. It’s a fair price for a chance to live again, isn’t it?

1.What kind of people does Trans Time serve? (No more than 2 words)

2.How much should one pay together, if he wants his body to be cooled and kept by Trans Time?

(No more than 2 words)

3.Why do people want to be frozen? (No more than 9 words)

4.What is the main idea of Paragraph 3? (No more than 6 words)
