Freezing weather can mean frostbite and _ unless a person is prepared. Do you know how to stay warm, dry and safe in such cold winter? 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 small cases of frostbite that affect only the skin may not suffer any lifelong damage. But if deeper tissue is affected, a person is likely to feel pain every time the area gets cold. If blood vessels are damaged, people can suffer an infection of gangrene . Sometimes, doctors have to remove frostbitten areas like fingers and toes. 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 unclear thinking. If not treated properly, Hypothermia can be deadly. A simple way to avoid cold-related injuries is to remember four basic steps. 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 instead of gloves. In gloves, the fingers are separated, so the hands might 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. L is 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. Can you guess what the D in C.O.L.D. stand for? D is 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. And here are two other things to keep in mind -- one for children and the other for adults. 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. Which of the following is NOT true about the C.O.L.D. according to the text? A) They are four basic steps to keep warm. B) Gloves can't protect us from cold sometimes. C) We should keep ourselves as dry as possible. D) They can protect us from injuries completely.

(Question)
What will city life be like in the future? Some people think that life in the cities is going to be horrible. They say that cities will become more and more crowded. As the number of people increases, there will be less space for each person. This overcrowding will cause other problems -- more crime, dirtier streets , and worse problems with traffic than we have now. How will people find enough drinking water, energy (such as gas and electricity ), and housing? Because life will be hard, people who live in cities will worry more, and they may become sick. For these reasons, some say that nobody will want to live in city areas. How can we deal with such problems as overcrowding, crime, and traffic? In some cities, thousands of people are already sleeping in the streets because there is little suitable housing -- and because houses are too expensive. The crime rate isn't going down. Instead, it is increasing so fast that many people are afraid to go out at night. Traffic is also getting worse. More and more often, traffic jams are so bad that cars don't move at all for several streets. These problems have been getting worse, not better, so many people see no hope for the future of the city. Los Angeles, California, for example, has no subway system and buses are slow. Instead, many commuters (, ) drive many miles from their homes to work. Many of these drivers spend several hours each day on busy freeways. New York, however, has a big transport system -- buses, commuter trains, and subways. Because the public transportation is crowded and dirty, many people drive private cars, and the traffic jams are worse than that in Los Angeles. A taxi driver complains, "I was driving home, but in forty-five minutes I moved only two miles! Finally, I turned off the engine and just sat there. A lot of people left their cars where they were in the middle of the street and went into a bar for a few beers!" On the other hand, some cities have clean, fast and pleasant public transportation systems. In Paris, France, and Toronto,... Which of the following sentences is NOT TRUE? A) Thousands of people are already sleeping in the streets. B) The crime rate isn't going down. C) The traffic jams are so bad that cars don't move at all for several streets. D) Many people have a positive attitude towards the future of the city.
