Most Americans get what money they have from their work; that is, they earn an income from wages or salaries. The richest Americans, however, get most of their money from what they own — their stocks, bonds, real estate, and other forms of property, or wealth. Although there are few accurate statistics to go by, wealth in American society appears to be concentrated in very few hands. More than 20 percent of everything that can be privately owned is held by less than one percent of the adult population and more than 75 percent of all wealth is owned by 20 percent of American adults. The plain fact is that most Americans have no wealth at all aside from their homes, automobiles, and a small amount of savings.
Income in the United States is not as highly concentrated as wealth. In 1917 the richest 10 percent of American families received 26.1 percent of all income, while the poorest 10 percent received 17 percent, mainly from Social Security and other government payments. The most striking aspect of income distribution is that it has not changed significantly since the end of World War II. Although economic growth has roughly doubled real disposable (可自由使用的) family income (the money left after taxes and adjusted for inflation) over the last generation, the size of the shares given to the rich and the poor is about the same. By any measure economic inequality is great in the United States.
The reality behind these statistics is that a large number of Americans are poor. In 1918, 14 percent of the population was living below the federal government’s poverty line, which at that time was an annual income of $ 9 287 for a nonfarm family of two adults and two children. In other words, about one out of seven Americans over 31 million people was officially considered unable to buy the basic necessities of food, clothes, and shelter. The suggested poverty line in 1981 would have been an income of about $11 200 for a family of four. By this relative definition, about 20 percent of the population or more than 45 million Americans are poor.
What does the majority of the Americans have in terms of wealth?
A. Their income and savings.
B. Everything they own in their homes.
C. Actually, they have no wealth at all.
D. Their house, cars and small amounts of savings.
What is the percentage of wealth that is in the hands of most Americans?
A. More than 25%. B. Less than 25%.
C. More than 75%. D. Less than 20%.
Why is economic inequality still great in the US in spite of the economic growth?
A. Because the proportion of income received by the rich and the poor remains almost the same as in 1917.
B. Because the economic growth has widened the gap of the family income between the rich and the poor.
C. Because income in the US is still concentrated in the hands of the richest 10% of American families.
D. Because some Americans made great fortunes during the Second World War.
What can we learn from comparison of the two poverty lines in the last paragraph?
A. The poverty line of 1918 is more favorable to the poor than that of 1981.
B. The 1981 line didn’t leave much to the poor.
C. There were more Americans who were officially poor by the 1981 line.
D. There were more Americans who were officially poor by the 1918 line.
From the last two sentences we can see that 1981 government’s poverty line _______.
A. was of no good for the poor B. was not put into operation then
C. was officially approved D. was not helpful to the poor

People have been painting pictures for at least 30,000 years. The earliest pictures were painted by people who hun??ted animals. They used to paint pictures of the animals they wanted to catch and kill. Pictures of this kind have been found on the walls of caves in France and Spain. No one knows why they were painted there. Perhaps the painters thought that their pictures would help them to catch these animals. Or per??haps human beings have always wanted to tell stories accord??ing to pictures.
About 5,000 years ago the Egyptians and other people in the Near East began to use pictures as a kind of writing. They drew simple pictures or signs to represent things and ideas, and also to represent the sounds of their language. The signs these people used became a kind of alphabet(字母表).
The Egyptians used to record information and to tell sto??ries by putting picture-writing and pictures together. When an important person died, scenes and stories from his life were painted and carved on the walls of the place where he was bur??ied. Some of these pictures are like modem comic-strip sto??ries. It has been said that Egypt is the home of the comic-strip. But, for the Egyptians, pictures still had magic power. So they did not try to make their way of writing simple. The ordinary people could not understand it.
By the year 1,000 BC, people who lived in the area a-round the Mediterranean Sea had developed a simpler system of writing. The signs they used were very easy to write, and there were fewer of them than in the Egyptian system. This was because each sign, or letter, represented only one sound in their language. The Greeks developed this system and formed the letters of the Greek alphabet. The Romans copied the idea, and the Roman alphabet is now used all over the world.
These days we can write down a story, or record informa??tion, without using pictures. But we still need pictures of all kinds: drawings, photographs, signs and diagrams. We find them everywhere: in books and newspapers, in the streets, and on the walls of the places where we live and work. Pic??tures help us to understand and remember things more easily, and they can make a story much more interesting.
6. Pictures of animals were painted on the walls of caves in France and Spain because ________.
A. the hunters wanted to see the pictures B. the painters were animal lovers
C. the painters wanted to show imagination D. the pictures were thought to be helpful

A. the former was easy to write B. there were fewer signs in the former

8. Which of the following statements is TRUE?
A. The Egyptian signs later became a particular alphabet.
B. The Egyptians liked to write comic-strip stories.
C. The Roman alphabet was developed from the Egyptian one.
D. The Greeks copied their writing system from the Egyp??tians.
9. In the last paragraph, the author thinks that pictures __________.
A. should be made comprehensible B. should be made interesting
C. are of much use in our life D. are disappearing from our life

Our surroundings are being polluted faster than nature and man’s present efforts cannot prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials.
What can explain and solve this problem? The fact is that pollution is caused by man, by his desire for a modern way of life. We make “increasing industrialization”(工业化)our chief aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the countryside into the cities, eager for the benefits of our modem society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourselves where we are going and why? It makes one think of the story about the airline pilot (飞行员) who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour.

In the 1960s,medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They found out that any major change can be stressful. Negative events like “serious illness of a family member” were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not show how you deal with stress—it only shows how much you have to deal with. And we now know that the way you deal with these events has a great effect on your chances of staying healthy.
By the early 1970s,hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Women's magazines ran headlines like “Stress causes illnesses”.If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. ven if stressful events are dangerous, many—like the death of a loved one—are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription(处方) for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be ?completely? free of stress would never marry, have a child, take a new job or move.?
The idea that all stress makes you sick also takes no notice of what we know about people. It is supposed that we're all weak and passive in the face of difficulty. But many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change or challenge can lead to boredom, and physical and mental damage.?
The result of Holmes-Rahe's medical research tells us _______.?
A. the way of dealing with major events may cause stress?
B. what should be done to avoid stress?
C. what kind of event would cause stress?
D. how to deal with sudden changes in life?
The studies on stress in the early 1970's led to_______.?
A. widespread worry over its harmful effects?
B. great fear about the mental problems it could cause?
C. a deep research into illnesses connected with stress?
D. popular avoidance of stressful jobs?
According to the passage people who have experienced ups and downs may become_______.
A. discouraged when faced with difficulty
B. physically and mentally weak?
C. more experienced in the face of difficulty
D. uninterested in what happens to them?
What's the purpose of writing the text??
A. To tell people the discoveries about stress.?
B. To tell people how to keep healthy.?
C. To help people avoid stressful events.?
D. To help people view stress properly.
