Davidson’s article is one of a number of pieces that have recently appeared making the point that the reason we have such stubbornly high unemployment and declining middle-class incomes today is largely because of the big drop in demand because of the Great Recession, but it is also because of the advances in both globalization and the information technology revolution, which are more rapidly than ever replacing labor with machine or foreign workers.
In the past, workers with average skills, doing an average job, could earn an average lifestyle. But, today, average is officially over. Being average is just won’t earn you what it used to. It can’t when so many more employers have so much more access to so much more above average cheap foreign labor cheap robotics, cheap software, cheap automation and cheap genins. Therefore, everyone needs to find their extra – their unique value contribution that makes them stand out in whatever is their field of employment.
Yes, new technology has been eating jobs forever, and always will. But there’s been an acceleration. As Davidson notes, “ In the 10 years ending in 2009, factories shed workers so fast that they erased almost all the gains of the previous 70 years; roughly one out of every three manufacturing jobs – about 6 millions in total – disappeared.”
There will always be change – new jobs, new products, new services. But the one thing we know for sure is that with each advance in globalization and the I.T. revolution , the beat jobs will require workers to have more and better education to make themselves above average.
In a world where average is officially over, there are many things we need to do to buttress employment, but nothing would be more important than passing some kind of G.I. Bill for the 21st century that ensures that every American has access to post-high school education.
The joke in Paragraph 1 is used to illustrate
A.the impact of technological advances
B.the alleviation of jobs pressure
C.the shrinkages of textile mills
D.the decline of middle-class incomes
But in a society of rapidly changing social and moral values, parents and children often disagree about what is important and what is fight.
(77) Arguments may concern such unimportant matters as styles of dress or hairdos. But quarrels may also concern school work, after school jobs, decisions, use of the family car, dating, and sex behavior. Some families have serious problems with teenagers who drop out of school, run away from home, or use illegal drugs. Because so much publicity is given to the problem teenager, one gets the impression that all teenagers are troublemakers. Actually, relatively few adolescents do anything wrong, and nearly all grow up into "solid citizens" who fulfill most of their parents' expectations. In fact, recent studies show that the "generation gap" is narrowing. The vast majority of teenagers share most of their parents' values and ideas. Many parents feel that they get along with their adolescents quite well.
According to the writer, conflicts between husband and wife usually reflect ______.
A．feeling of hatred
B．power struggle
C．that they don' t care for each other
D．that they may appeal to divorce
Bacteria (细菌) are extremely small living things. While we measure our own sizes in inches or centimeters, bacterial size is measured in microns. One micron is a thousandth of a millimeter: a pinhead is about a millimeter across. Rod-shaped bacteria are usually from two to four microns long, while rounded ones are generally one micron in diameter. Thus, if you enlarged a rounded bacterium a thousand times, it would be just about the size of a pinhead. An adult human magnified by the same amount would be over a mile (1.6 kilometers) tall.
Even with an ordinary microscope, you must look closely to see bacteria. Using a magnification of 100 times, one finds that bacteria are barely visible as tiny rods or dots. One cannot make out anything of their structure. Using special stains, one can see that some bacteria have attached to them wavy-looking "hairs" called flagella. Others have only one flagellum. The flagella rotate, pushing the bacteria through the water. Many bacteria lack flagella and cannot move about by their own power, while others can glide along over surfaces by some little-understood mechanism.
From the bacterial point of view the world is a very different place from what it is to humans.To a bacterium water is as thick as molasses (糖蜜) is to us. Bacteria are so small that they are influenced by the movements of the chemical molecules around them. Bacteria under the microscope even those with no flagella often bounce about in the water. This is because they collide with the water molecules and are pushed this way and that molecules move so rapidly that within a tenth of a second the molecules around a flagellum have been replaced by new ones. Even bacteria without flagella are thus constantly exposed to a changing environment.
Which of the following is the main topic of the passage？
A．The characteristics of bacteria.
B．How bacteria reproduce.
C．The various functions of bacteria.
D．How bacteria contribute to disease.
The high point in railroad building came with the construction of the first transcontinental sys tem. In 1862 congress authorized two western railroad companies to build lines from Nebraska west ward and from California eastward to a meeting point, so as to complete a transcontinental crossing linking the Atlantic seaboard with the Pacific. The Government helped the railroads generously with money and land. Actual work on this project began four years later. The Central Pacific Company, starting from California, used Chinese labor, while the Union Pacific employed crews of Irish labourers. The two groups worked at remarkable speed, each trying to cover a greater distance than the other. In 1869 they met at a place called Promontory in what is now the state of Utah. Many visitors came there for the great occasion. There were joyous celebrations all over the country, with parades and the ringing of church bells to honour the great achievement.
The railroad was very important in encouraging westward movement. It also helped build up industry and farming by moving raw materials and by distributing products rapidly to distant markets. In linking towns and people to one another it helped unify the United States.
The major problems with America' s railroad system in the mid-19th century lay in ______.
A．poor quality rails and unreliable stopping systems
B．lack of financial support for development
C．limited railroad lines
D．lack of a transcontinental railroad

A．passes
B．goes
C．flashes
D．moves

Given the inclination toward change, it is not surprising that tradition plays a limited role in the American culture. Those who try to uphold traditional pattern of living or thought may be seen as rigid or "old-fashioned". In a society where change is so rapid, it is not uncommon for every generation to experience a "generation gap". Sometimes parents struggle to understand the values of their children, even religious institutions have had to adapt to contemporary need of their followers. Folk singers in church services, women religious leaders, slang versions of the Bible, all reflect attempts made by traditional institutions to "keep up with the times".
High rates of change, particularly in urban areas, have contributed to a focus on the future rather than the past or present. Some Americans believe that the benefits of the future orientation are achievement and progress which enable them to have a high standard of living. Others believe that high blood pressure and stomach ulcers are the results of such a life style.
As individuals in a culture, we all have an intuitive understanding about how time is regulated, usually we do not think about the concept of time until we interact with others who have a different time orientation. Although individuals from any now cultures may view time similarly, we often sense that in another culture, life seems to proceed at either a slower or faster pace. Knowing how time is regulated, divided, and perceived can provide valuable insights into individuals and their culture.
The American orientation toward the future might be demonstrated by ______.
A．the presence of religious institutions
B．the preference for "old-fashioned" parents
C．the limited role of tradition
D．the presence of folk singers in church services
Cream and butter contain pretty much the same substances, so why cream should sour much faster has been a mystery. Both are emulsions—tiny globules(小球) of one liquid evenly distributed throughout another. "The difference lies in what's in the globules and what's in the surrounding liquid", says Brocklehurst, who led the investigation. In cream, fatty globules drift about in a sea of water. In butter, globules of a watery solution are locked away in a sea of fat. The bacteria which make the food go bad prefer to live in the watery regions of the mixture. "This means that in cream, the bacteria are free to grow throughout the mixture", he says.
When the situation is reversed, the bacteria are locked away in compartments(密封仓) buried deep in the sea of fat. Trapped in this way, individual colonies cannot spread and rapidly run out of nutrients. They also slowly poison themselves with their waste products. "In butter, you get a self-limiting system which stops the bacteria growing", says Brocklehurst. The researchers are already working with food companies keen to see if their products can be made resistant to bacterial attack through alterations to the food's structure. Brocklehurst believes it will be possible to make the emulsions used in salad cream, for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning it into a solid lump.
The significance of Brocklehurst's research is that ______.
A．it suggested a way to keep some foods fresh without preservatives
B．it discovered tiny globules in both cream and butter
C．it revealed the secret of how bacteria multiply in cream and butter
D．it found that cream and butter share the same chemical composition
