Over the last 70 years, researchers have been studying happy and unhappy people and finally found out ten factors that make a difference. Our feelings of well-being at any moment are decided to a certain degree by genes. However, of all the factors, wealth and age are the top two.

Money can buy a degree of happiness. But once you can afford to feed, clothe and house yourself, each extra dollar makes less and less difference. Researchers find that, on average, wealthier people are happier. But the link between money and happiness is complex. In the past half-century, the average income has sharply increased in developed countries, yet happiness levels have remained almost the same. Once your basic needs are met, money only seems to increase happiness if you have more than your friends, neighbors and colleagues.

“Dollars buy status (social position), and status makes people feel better,” say some experts, which helps explain why people who can seek status in other ways, scientists or actors, for example, may happily accept relatively poorly-paid jobs.

In his research, Professor Alex Michalos found that the people whose desires, not just for money, but for friends, family, job, health, rose furthest beyond what they already had, tended to be less happy than those who felt a smaller gap. Indeed, the size of the gap predicted happiness about five times better than income alone. “The gap measures just blow away the measures of only income.”says Michalos.

Another factor that has to do with happiness is age. Old age may not be so bad “Given all the problems of aging, how could the elderly be more satisfied?” asks Professor Laura Carstensen. In one survey, Carstensen interviewed 184 people between the ages of 18 and 94, and asked them to fill out an emotion questionnaire. She found that old people reported positive emotions just as often as young people. Some scientists suggest older people may expect life to be harder and learn to live with it, or they’re more realistic about their time running out. Older people have learned to focus on things that make them happy and let go of those that don’t.

“People realize not only what they have, but also that what they have cannot last forever,” she says. “A goodbye kiss to a husband or wife at the age of 85, for example, may bring far more complex emotional responses than a similar kiss to a boy or girl friend at the age of 20.”

1.Some actors would like to accept poorly-paid jobs because the jobs__________.

A. make them feel much better

B. provide chances to make friends

C. improve their social position

D. satisfy their professional interests

2.Professor Alex Michalos found that people feel less happy if _________.

A. the gap between reality and desire is bigger

B. they have a stronger desire for friendship

C. the hope for good health is much greater

D. their income is far below their expectation

3.We can infer from the passage that older people _________.

A. would like to have more goodbye kisses than young people

B. are used to living a hard life because they are kind to others

C. express their positive opinions just as some young people do

D. find it easier to feel happy because they are more realistic

4.According to the passage, the feeling of happiness _________.

A. increases gradually with age

B. is controlled partly by desires

C. has little to do with wealth

D. is decided mostly by genes

The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even eat it.

Man has been polluting the earth. The more people, the more pollution. Many years ago, the problems was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.

Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.

Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollutions. It is caused by heavy traffic. We are sure that if there are fewer people driving there will be less air pollution.
