Cut the Carbon Footprint

Everything you do leaves a “ carbon footprint”(碳足迹). For example, When you travel in a taxi, the car gives off (排放) CO₂ into the air. CO₂ is a greenhouse gas. Greenhouse gases make the earth become warm. To protect our environment, we need to leave less of a “carbon footprint”. How big is your carbon footprint? To get an idea, take a look at the following numbers.

Living areas

l  TV sets and DVD players produce 723kg of CO₂ a year.

l  If you turn them off when you’re not using them, you can cut that number by 108kg.

Laundry room (洗衣房)

   Drying clothes in a dryer produces a lot of CO₂

l  If you use your dryer five times per week, you produce 185kg of CO₂ per year.

l  Dry your clothes in the sun instead.

Bathroom

l  If you take an eight-minute shower every day, you produce 616kg of CO₂ a year.

l  If you only use six minutes to take a shower, you can cut that number by 154kg a year.

根据短文内容，判断下列句子的正误，正确的用“T”，错误的用“F”。 1 CO₂ is a greenhouse gas that can make the earth warm.

2 Watching TV and traveling in a taxi can produce little CO₂.

3 If we use a dryer five times per week, we produce 154kg of CO₂ per year.

4  If we spend less time taking a shower, we can cut the number of CO₂.

5 The less of a “ carbon footprint” we leave, the better our environment will become.

The world is becoming smaller by using modern traffic, TV, telephone and so on. Life today is easier than it was hundreds of years ago, but it has also brought new problems. One of the biggest is pollution. Pollution comes in many ways. We see it, smell it, drink it and even hear it.

The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. Man is now slowly polluting the whole world.

Air pollution is still the most serious. It’s bad to all living things in the world. Water pollution kills our fish and pollutes our drinking water, noise pollution makes us become angry more easily. The pollution of SO₂ is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is true that if there are fewer people driving, there will be less air pollution.

Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city. So the less pollution there is, the better life people will have.

It is very important to be able to control yourself. Losing control may bring things that would never want to see. We can learn something from the following story.

Once a boy often made trouble. His mother gave him many nails （钉子）. She told him to hammer （锤，钉） one in the garden fence （栅栏）, every time he lost his patience （耐心） and fought with someone. The first day he hammered 27 nails. In the following weeks he learned how to control himself better and the number of the nails he hammered became smaller and smaller. He learned it was easier to control himself than to hammer nails.

The day finally came when he didn’t hammer any nails. He went to tell his mother about it. Then his mother told him to pull off a nail from the fence each time he didn’t lose his patience. After some days he told his mother that all the nails had been pulled off. Thus, she took him to the fence and said to him, “You’ve behaved（表现） well, but look at all the holes in the fence. The fence will never be again like it was before. When you fight with someone, you leave wounds（伤口） in him like these. The trouble may be over, but the wounds will always be there.”

So, learn to control yourself before you hammer the nails in the fence. Try not to leave any holes in your past.

    A man once had a dream about the Black Forest In Germany. In his dream he was walking in the forest when two men ran out and tried to throw him to the ground. He ran off as fast as he could, but they followed him. He reached a place where he saw two roads in front of him, one to the right and the other to the left. Which road should he take? He heard the two men behind him, getting nearer, and at the same time he heard a voice in his ear. It told him to go to the right, and he did so. He ran on and soon came to a small hotel. He was received there kindly and given a room, and he was saved from the two men. That was the dream.

Dogs can also go to school to learn how to help people who cannot hear. If a person cannot hear, we say he or she is deaf.

Dogs who help deaf people must learn many different sounds. Then they must be able to show the deaf person what is making the sound. When they hear a visitor at the door, dogs learn to walk to the deaf person and then walk to the door. And if a telephone rings, they walk to the deaf man or woman and then walk to the telephone. These dogs can also help deaf mothers. If a baby is crying in another room, dogs walk to the mother and then to the baby. These dogs wear a yellow coat to show that they are special dogs that are helping a deaf person. There have been many times when these dogs have saved a life. You may see in a newspaper that a dog heard a fire alarm and lay down near the deaf person's feet. That is the sign for danger. The person knows that something is wrong and can go away from the fire.

Special dogs can also help people who are disabled in various ways. For example, dogs can pull off their gloves or socks! Think how difficult your life would be if you were blind, deaf or disabled! But if you had a special dog like this to help you, your life would be much easier.
