In the years since World War II, Americans have awakened, as never before, to the world’s art heritage, and have discovered the startling truth that a sizable and important :part of heritage in their own backyard. U.S. art, as Americans in general are beginning to realize, is neither a series of blurred engravings out of half-forgotten school histories nor a dim reflection of painting abroad. For the past two centuries it has stood on its own feet, comparing favorably with the art of every other nation except France. Drawing depth and drama from history it helps illustrate, it has reflected not European painting but American life - rough and smooth, tumultuous and diverse. And though it is a great river of many sources and many passing moods, its strongest single current throughout is a searching realism. The revered champion of that tradition in America today is Edward Hopper.Less recognized, but equally true, is the fact that, at 74, Edward Hopper, painter extraordinary, expresses the present moment of American life with all the vigor and attachment of youth. One remark of Emerson’s applies very well to Hopper’s painting: “In every work of genius we recognize our own rejected thoughts: they come back to us with a certain alienated majesty”. Hopper is clearly a genius of this kind; he paints not only what Americans have seen from the corners of their eyes, but also what they have dimly thought and felt about.Hopper has opened a whole new chapter in American realism, painting a new world of men, Cole a world of nature, and Homer a world of struggle between the two, Hopper paints the raw, uneasy world that Americans have built on this land.1. What truth did Americans discover in art field?2. What was the major characteristic of Americans’ paintings?3. What does the statement “It is a great river of many sources…?” Imply? (Para. 1)4. What is Hopper famous for?5. In which aspects can Hopper’s painting be regarded as genius work?

One of the most widespread and important types of learning is operant conditioning, which involves increasing a behavior by following it with a reward, or decreasing a behavior by following it with punishment. For example, if a mother gives a boy his favorite snack every day for his cleaning up his room, before long the boy may spend some time each day cleaning his room in anticipation of the snack. In this example, the boy’s room-cleaning behavior increases because it is followed by a reward.Unlike classical conditioning, in which the conditioned and unconditioned stimuli are presented regardless of what the learner does, operant conditioning requires action on the part of the learner. The boy in the above example will not get his snack unless he first cleans up his room. The term operant conditioning refers to the fact that the learner must operate, or perform a certain behavior, before receiving a reward or punishment.Some of the earliest scientific research on operant conditioning was conducted by American psychologist Edward L. Thorndike at the end of the 19th century. Thorndike’s research subjects included cars, dogs, and chickens. To see how animals learn new behaviors. Thorndike used a small chamber that he called a puzzle box. He would place an animal in the puzzle box, and if it performed the correct response (such as pulling a rope, pressing a lever, or stepping on a platform), the door would swing open and the animal would be rewarded with some food located just outside the cage. The first time an animal entered the puzzle box. It usually took a long time to make the appropriate response required to open the door. Eventually, however, it would make the appropriate response by accident and receive its reward: escape and food. As Thorndike placed the same animal in the puzzle box again and again, it would make the correct response more and more quickly. Soon it would take the animal just a few seconds to earn its reward.Based on these experiments, Thorndike developed a principle he called the law of effect. This law states that behaviors that are followed by pleasant consequences will be strengthened, and will be more likely to occur in the future. Conversely, behaviors that are followed by unpleasant consequences will be weakened, and will be less likely to be repeated in the future, Thorndike’s law of effect is another way of describing what modern psychologists now call operant conditioning.1. The difference between classical conditioning and operant conditioning is that _____.2. What’s the occupation of Edward L. Thorndike?3. Why could the animals in the puzzle box gibe correct response more and more quickly?4. Which of the following may be inferred according to the law of effect?5. The phrase “swing open” (Line 6. Para. 3) means _____.

Daydreaming is a healthy and natural act of the human psyche, according to American Health magazine. It is at its peak from noon to 2 pm, when body temperature is at its highest.The phenomenon also reveals a great deal about us. Some people use their fantasies to help them make decisions, while others “escape” to enhance their sense of well-being and creativity, says Pam L. Blondin, a clinical social worker and director of programs and services at the Child and Family Service of Sagisaw County, Michigan.“Daydreaming can be an escape that feels good in the midst of a hectic day”, Blondin explained. “It’s a good stress reducer at the desk. Getting away from it all for a while, so to speak, isn’t something that is going to hurt anyone. Sometimes it helps people tap into creativity that is not always conscious.”Daydreaming helps people cope with a wide range of problems, partly providing insight into our emotional needs, as well as unmet needs and goals, experts say. By some estimates, approximately half our waking thoughts consist of daydreams and fantasies.“Daydreaming keeps our personal agendas in front of us”, says psychologist Eric Klinger. Daydreaming plays an important role in organizing our lives, he says. “We can actually learn something by paying attention to the whimsical interludes that occasionally interrupt our more structured thought.”Active, imaginative lives are vital to children’s development, American Health reports. Most children start fantasizing between the ages of 2 and 5. “Children struggle to understand life’s complexities, from jet planes to the TV images flashed into their living rooms,” says Yale University psychologist Jerome L. Singer. He believes that make-believe helps youngsters break down elements to a level they can understand. “Unless a child’s daydreaming is interfering with progress in school or hampering his/her social skills, there is no need to discourage it,” Singer says.1. Daydreaming does all of the following except _____.2. What is the word “hectic” (Line 1, Para. 3) most likely to mean?3. Children may start to daydream as early as they are _____ years old.4. It can be inferred that _____.5. Which of the following statements is not true according to the passage?

The banking revolution in America is as much about attitudes and assumptions as about size and structure. For centuries, Americans have distrusted banks. In the 1830s, Andrew Jackson denounced and destroyed the Second Bank of the United States, which existed “to make the rich richer” at the expense of farmers, mechanics and laborers”. In the 1930s, banks were blamed for helping cause the Depression. The wonder, then, is that the latest wave of bank mergers—the largest ever—has inspired little more than a bewildered and, perhaps, irritated shrug from the public.As banks grow bigger, they seem less fearsome. Why? The answer is that banks have shrunk in power even as they have expanded in size. Traditionally, banking has been a simple business. Deposits come through one door, loans go out through another. Profits derive from the “spread” between interest rates on deposits and loans. If savers and borrowers cannot go elsewhere, banks are powerful. And if there are other choices, banks are less powerful. And so it is.We inhabit an age of superabundant credit and its purveyors. A century ago, matter were different. Small depositors could choose from only one or several local banks; getting a loan meant winning the good graces of the neighborhood banker. Even big corporations depended on a few big banks or investment houses.John Reed or Huge McColl—the heads of Citicorp and Nations Bank—are not controlled through stock and positions on corporate boards—a third of U.S. railroads and 70% of the steel industry. A railroad executive once cheerfully confessed his dependence on Morgan’s capital: “If Mr. Morgan were to order me tomorrow to China or Siberia...I would go.”No bankers today inspired such awe or fear. Time, technology and government restrictions weakened bank power. In the 1920s, auto companies popularized car loans. National credit cards originated in 1950 with the Dinners Club card. In 1933, the Glass pensions and the stock market competed for consumer savings. As a result, banks command a shrinking share of the nation’s wealth: 20 percent of assets of financial institutions in 1997, down from 50 percent in 1950.1. Traditionally, Americans’ altitude towards banks is one of _____.2. Why are John Reed and Hugh McColl not as well-known as J. P. Morgan?3. The word “spread” in Para. 2 most probably means _____.4. Which of the following statements is true? 5. What does the author mainly talk about in the passage?

American researchers report limited success using gene therapy to treat the genetic blood disease hemophilia.Hemophilia results when a gene fails to produce the protein needed for the blood to clot, or change from a liquid to a solid. The defective gene is passed from parents to children. People with hemophilia suffer uncontrolled bleeding. This can result in pain, tissue swelling and permanent damage to joints and muscles. One in every ten-thousand males has the most common kind of hemophilia. It is extremely rare for females to have it. Patients can be treated with the missing clotting substance. They generally can lead normal lives.Scientists say gene therapy may be a possible way to cure hemophilia in the future. Most gene therapies use a virus to place a good copy of a gene into a cell that needs it. The new gene helps the body operate normally. For people with hemophilia, this means that clotting genes placed in the body would result in blood cells that clot normally.Researchers consider hemophilia the best disease for gene therapy because it is caused by a single defective gene. Also, only a small increase in the missing clotting substance could provide good results. Scientists at the Beth Israel Deaconess Medical Center in Boston, Massachusetts carried out the experiment. They reported the results in the New England Journal of Medicine. They tested gene therapy in six patients with severe hemophilia.First, they removed skin cells from the patients’ arms. The researchers grew the cells in the laboratory. The added copies of the needed gene taken from healthy people. Then they created hundreds of millions of genetically changed cells. They placed these cells into the patients’ stomachs. After four months, the amount of blood clotting substance in the blood increased in four of the six patients. Some of the patients reported a decrease in bleeding problems. However, ten months later, the clotting substance was no longer in the patients’ blood. It is not clear if the implanted cells died or the added genes slopped working.The researchers say the study showed that gene therapy is safe for people with the most common kind of hemophilia. But others expressed concern about the treatment because the effects were only temporary.1. In a family where the father is with hemophilia, which one is most likely to suffer from it?2. Which among die following can be a symptom of hemophilia?3. Which among the following is NOT one step of gene therapy?4. What does the result of the experiment show?5. Which is true according to the passage?
