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.

Many strong and out-of-control emotions are recognized as an illness. People who are always very sad have depression (抑郁症); those who worry a lot have anxiety.
But what about anger problems? Anger is largely viewed as a secondary emotion – one caused by other emotions. People are thought to be angry because they are sad, anxious or stressed. In the past, many doctors didn’t accept the idea that anger could be a problem all on its own.
Today, though, a growing number of mental health experts think that anger is a serious problem that needs its own treatment.
How to tell the difference between “normal” anger and “anger problem” is difficult. After all, everyone gets really mad from time to time. Experts point out a few ways.
Disordered anger, as it is sometimes called, tends to be of greater intensity (强度). It takes very little to set off a person with an anger problem, and their responses (反应) are very strong. An example: While most people would get upset if a driver cut them off, someone with disordered anger might try to chase down the car and force it off the road.
And in cases of disordered anger, the person gets angry more frequently and his/her anger lasts longer. For most people, angry feelings disappear quickly. But people with anger problems often stay angry for days, weeks or even years; their feelings of anger don’t disappear over time.
Consequences are also important to consider: Disordered anger often damages people’s lives. “It interferes (干扰) with people’s relationships and their jobs,” says Raymond Chip Tafrate, a US psychologist. “Even their health is affected.”
Anger clearly increases the risk of certain health problems, as many studies have shown. “When a person is angry, their heart beats faster and their blood pressure goes up,” says Howard Kassinove, a professor at Hofstra University in New York. Over time, these changes take their toll on the body, he adds.
Experts suggest that people with an anger problem take anger-management programs. The programs teach people to control their responses to stressful situations through the use of relaxation techniques. The programs sometimes include life-skills training as well: increasing someone’s level of competence (竞争)– whether on the job or as a parent or partner – helps bring down stress and cut angry feelings.
